hile driverless cars are still a dream for the automotive industry, driverless trucks have been in operation on mine sites around the world for some time. Rio Tinto began trials with autonomous trucks ten years ago. Approximately a third of its fleet of 400 haul trucks in the Pilbara region of Western Australia is currently autonomous, and now they’re doing it with trains. In July we learned that Autohaul, the autonomous train that Rio Tinto likes to call ‘the world’s largest and longest robot’, made its first ‘solo’ delivery of iron ore in the Pilbara. Rio Tinto operates about 200 locomotives on more than 1000 miles of track in the Pilbara, transporting ore from 16 mines to four port terminals. AutoHaul is on schedule to complete by the end of the year, unlocking significant safety and productivity gains for the business. Also in the summer came the news that Newmont Mining had completed its Northwest Exodus project, extending mine life at the Exodus underground operation in the Carlin North area in Nevada. This project was designed to support autonomous operations and is currently running two autonomous mobile loaders and pilot-testing autonomous drills. The operation is also fitted with high-bandwidth underground WiFi. Trucks are not always the answer, however. Our cover story for this issue describes some of the innovative technologies
employed by Vale at its S11D iron ore project in Brazil, including a truckless transportation system that uses movable crushers and conveyor belts to get ore to the processing plant, instead of the 100 or so trucks that would have been required otherwise. Horses for courses, you might say. On the other hand, at the Brucutu mine in Minas Gerais, Vale has been trialling its own system of autonomous trucks, controlled not by humans in the cab but by computer systems, GPS, radars and artificial intelligence. When the entire fleet is replaced by automated trucks in early 2019, Brucutu will be the first Brazilian mine to operate autonomously. Joint venture partners Hancock Prospecting and Rio Tinto have recently opened the Baby Hope iron ore mine, a fourth Hope Downs operation in the Pilbara. The JV intends to retrofit 28 haul trucks at the Hope Downs 1 mine with autonomous haulage system (AHS) technology and three production drills at the Hope Downs 4 mine with autonomous drilling system (ADS) technology by 2020. When one mine uses trucks and another uses conveyors, it shows that different mines require different solutions, rather than slavishly following the technology flavour of the month.

O
ne of the largest metals and mining companies in the world, Vale is the world’s largest producer of iron ore and iron ore pellets. After the opening of the S11D complex in the Brazilian Amazon, it now also boasts the largest single iron ore mining operation anywhere in the world. To give it its full title, the Eliezer Batista S11D Complex (named after the Brazilian engineer who served two spells as the company’s CEO), was inaugurated in December 2016 and started commercial operations in January 2017. At a cost of US$14.3 billion the complex comprises a mine and an iron ore processing plant with three production lines - each with a processing capacity of 30 million tons per year. Together with the associated railroad and port logistics, it represents the largest private investment made in

Brazil in this decade. Of the $14.3 billion invested in the project, $6.4 billion was spent on the mine and plant, with the remaining $7.9 billion accounted for by the construction of a 101km-long railroad branch, and the expansion of both the Carajás Railroad and the Ponta da Madeira Maritime Terminal in São Luís. S11D seems an unusual name for a mining complex, but the project was named after its location on block D of the S11 body, on the South Range of Carajás. The plan started to take shape in 2001, when the first technical and economic feasibility studies were developed. The preliminary license was granted in June 2012 and the installation license was issued a year later. The operations license was granted in December 2012, with the mine having an expected lifespan of 30 years.
The ramp-up will be phased over four years to maximize margins and optimize the mix of products. The nominal production of 90 million tons per year should be reached in 2020, by which time the Northern Region, which also includes the mines in the Carajás Complex and Serra Leste, is expected to deliver 230 Mtpa. Together with new mines in operation in Carajás and expansion projects already implemented in Minas Gerais, S11D will enable Vale to increase its competitiveness in the international market over the next few years. At the peak of the construction works, the project absorbed a workforce of more than 40,000 workers. Once the ramp-up is completed, about 2,700 employees will be working directly at the plant and mine and over 10,000 indirect jobs will have been created.

“One of the major technological features of S11D is the truckless system which uses movable crushers and conveyor belts to extract the iron ore and transport it to the processing plant, instead of the 100 or so trucks that would have been required otherwise”
Vale has taken an innovative approach to the development of this mine, to minimise its environmental impact and at the same maximise energy efficiency. One of the major technological features that make the S11D a unique iron ore project is the adoption of a truckless system to replace fixed crushers and off highway trucks. The system uses movable crushers and conveyor belts to extract the iron ore and transport it to the processing plant, instead of the 100 or so trucks that would have been required otherwise. This reduces fuel consumption by over 70 per cent and saves a fortune on consumables such as tyres, filters and lubricants. Truckless technology is commonly used in coal mining, where the ore layers are continual and homogeneous. The characteristics of the S11D’s mineral body were also conducive to this method, since it is an elongated, relatively homogenous mineral body, 9.5 km long by 1.5 km wide, and 300 metres deep. Including a long distance conveyor over 9 kilometres long, there is a total of 68 km of conveyor belts operating in the mine. Another technological feature of S11D is dry processing of the ore, with equipment developed by Vale in partnership with manufacturers, specially tailored to process the natural high moisture ore of Carajás. Dry processing is already in use in some plants in Carajás and will enable a 93% reduction in water consumption, as well as huge savings on electricity. The use of dry processing also eliminates the need for a tailings dam. The ultrafine fraction of high grade iron ore, which would end up in the dam, will be part of the final product. Another significant feature of the construction phase was the modularization of the processing plant. The buildings were divided into 109 modules during project development and engineering, and these were assembled at a construction site over 40 km away from where the plant was ultimately built. The modules were transported on a road specially prepared and paved to support their weight and dimensions, before being welded and bolted together as if they were large Lego pieces. The transportation of the 109 modules was completed in August
2015 and their assembly at the mine was finished in October of the same year. After processing, the iron ore will be carried by rail to the expanded Ponta da Madeira Maritime Terminal (TMPM) in São Luís. The iron ore train is one of the largest cargo trains in the world in regular operation, 3.3 kilometres long with 330 cars each carrying 100 tons of iron ore. The Brucutu mine in Minas Gerais is responsible for the majority of the Southeast System’s iron ore production. Here Vale has been trialling a system of autonomous trucks, controlled not by humans in the cab but by computer systems, GPS, radars and artificial intelligence. The teams that supervise the process can be located a long way from the operations. When the entire fleet is replaced by trucks with the new technology in early 2019, Brucutu will be the first Brazilian mine to operate autonomously. There will be obvious safety benefits with fewer people involved at the mine site. On top of that Vale expects to obtain an increase of around 15 per cent in the equipment’s lifespan. The average speed of the trucks is expected to increase, while fuel consumption and maintenance costs are expected to decrease by ten per cent. The experience with autonomous equipment in Brucutu will help Vale to determine the future of the use of technology in other operations.
Pellets
Vale has iron ore operations in four regions of Brazil known as the Northern, Southeastern, Southern and Midwestern Systems. It also has iron ore pellet operations in several locations, some of which are conducted through joint ventures. Pellets are small balls of iron ore used in the production of steel. They are made with technology that uses the powder generated during the ore extraction process, which was once considered waste. The company currently operates nine pellet plants in Brazil, two in Oman in the Middle East and has 25% stakes in two pellet companies in China. The world’s biggest producer of pellets, Vale’s Tubarão Complex in Brazil covers an area of 14 km2. This is home to the biggest railway yard in World Mining Magazine www.ogsmag.com

Latin America and eight pelletizing plants, which together produce more than 20 million metric tons of pellets per year. Besides the operational facilities, the complex also has an administrative building, eight canteens, bank branches and a post office. In recent years over R$700 million has been invested in improvements and environmental controls to reduce dust emissions, reduce water consumption in production processes and recycle much of the waste produced. Vale has adopted the latest environmental management practices in all its operations within the Tubarão Complex, concluding a series of upgrades to its terminals in March 2016. These included Piers I and II, used to load iron ore and pellets, and the Praia Mole Terminal (TPM), used for discharging coal. The work
World Mining Magazine www.ogsmag.com

began in 2015 and included structural investments and reviews of the processes used to handle solid grains, with the objective of preventing material loss during ship loading and discharging operations. The Tubarão Complex has been producing iron ore pellets since the late 1960s, but a couple of the plants, Tubarão II and São Luís have just reopened this year after being dormant for a few years in response to slow global demand.
Nickel
Vale is also the world’s largest producer of nickel, with operations in Canada, Indonesia and New Caledonia as well as Brazil. One of the most versatile metals, nickel is hard but malleable, resists corrosion and maintains its mechanical and physical properties even when
subjected to extreme temperatures. Vale’s operations in Sudbury, Ontario have been working for more than 100 years. With six mines, a mill, a smelter, a refinery and nearly 4,000 employees it is also one of the largest integrated mining complexes in the world. The sulphide ores contain more than just nickel, however. Other elements are often found, including copper, cobalt, platinum group metals, gold and silver. Thompson, Manitoba is 740 kilometres north of Winnipeg and is named after John F. Thompson, chairman of International Nickel when a significant body of ore was discovered there in 1956. Facilities there consist of the Thompson and Birchtree Mines along with the Thompson Mill, Thompson Smelter and Thompson Refinery. Operations at Vale’s open-pit mine and concentrator at Voisey’s Bay in
vale an iron grip on the market
“The iron ore train is one of the largest cargo trains in the world in regular operation, 3.3 kilometres long with 330 cars each carrying 100 tons of iron ore”
Newfoundland and Labrador began in 2005. This 6,000 tonnes-per-day facility produces two types of concentrate: nickel-cobalt-copper concentrate and copper concentrate. Since Voisey’s Bay is located in an area subject to land claims by both the Innu Nation and the Nunatsiavut Government, separate Impacts and Benefits Agreements (IBA) have been negotiated with the two aboriginal groups. Vale is currently optimizing its nickel operations across Canada, as part of an overall strategy to prioritize value over volume, reduce emissions and comply with local regulations. It is phasing out its smelting and refining activities in Thompson, Manitoba to focus on nickel concentrate production. As a result, it will concentrate more of its refining and smelting activities in Sudbury, where it will focus on the production of copper concentrate, copper matte and refined nickel. The majority of the feed from Thompson will be sent to Sudbury or Long Harbour in Newfoundland and Labrador to be refined. The Long Harbour Processing Plant (LHPP) began operations in 2014 and currently employs approximately 500 people. The LHPP and the Voisey’s Bay mine and concentrator are now an integrated operation. Nickel concentrate from Voisey’s Bay is shipped to Long Harbour to be processed into finished nickel and associated copper and cobalt products. In designing the LHPP, Vale sought to develop a new, more efficient process for processing Voisey’s Bay concentrate than traditional smelting and refining. After a multi-phase $200 million research and development program with support from Technology Partnerships Canada, the Long Harbour processing plant was built as a commercial-scale hydromet facility (using hydrometallurgical technology). In June 2018 Vale completed transactions with Cobalt 27 Capital and Wheaton Precious Metals for the sale of a combined 75% cobalt stream from the Voisey’s Bay nickel mine. The transactions cover the cobalt by-product of the Voisey’s Bay mine, including the ramp-down of production from the existing surface mine and the life of mine production from the Voisey’s Bay underground mine
expansion project (VBME). Wheaton paid US$390 million for a 42.4 per cent share of finished cobalt production from Voisey’s Bay from 1 January 2021 onwards. Cobalt 27 paid $300 million for a 32.6 per cent share. Once they have received 31 million and 23.8 million pounds of cobalt respectively, the streamed percentages will be halved until production at Voisey’s Bay comes to an end. The streaming deal enables the development of VBME, Vale’s first significant investment announcement in recent years. A feasibility study was completed in early 2015 to expand Voisey’s Bay operations underground, but although the project was approved by Vale’s board of directors, it was put on hold due to difficult market conditions. To secure a smooth transition from the open pit to the underground mine, Vale says nickel production from Voisey’s Bay will be maintained at 38 ktpa from 2018 to 2020, ramping up to 45-50 ktpa of nickel contained in concentrate from 2024 onwards. “By unlocking the value of the cobalt by-product at Voisey’s Bay through this streaming deal, Vale has found a way to resume substantive work on the underground project in Voisey’s Bay and support the market’s increasing demand for nickel, copper and cobalt, as well as uphold its commitment to the Government, our indigenous stakeholders and the people of Newfoundland and Labrador, Canada,” commented Eduardo Bartolomeo, executive officer for base metals.
Awards for Canadian operations A lot has been happening at Voisey’s Bay in the last few years, including the receipt of The TSM Community Engagement Excellence 2017 award for the contribution of Vale’s shipping program to the lifestyle of local people. The Innu and Inuit on the North Coast of Labrador have a deep cultural connection to the land-fast sea ice, which serves as a transportation route for harvesting and to access other coastal communities. Vale’s Voisey’s Bay operation uses Anaktalak Bay shipping route to ship its products and to resupply the site. Vale and local communities and stakeholders have collaborated for more than a World Mining Magazine www.ogsmag.com

decade to ensure shipping has minimal interference with Aboriginal traditional lifestyles and that residents can safely cross the ship’s track. Continued collaboration led to the development of floating pontoon-type bridges, which are deployed across the ship’s fresh track at key locations along the 40-kilometre shipping route. Reflective markers and signage are added along the route to ensure safe crossing. When the track freezes, additional “ice bridges” are established at other locations. Once safe crossing locations are established, a multi-faceted communications system alerts residents of their locations as well as shipping activity. Community input has been paramount to the program’s success and is also reflected in other aspects of the

agreement. For example, there are two six-week closure periods when shipping cannot take place: in the fall when ice is forming and in the spring when ice is breaking up. Closure periods have also been adjusted to reflect weather conditions and public holidays. “We are humbled and honoured to be recognized with the TSM Community Engagement Excellence Award,” said Jennifer Maki, CEO of Vale Canada. “This award belongs equally to the Innu and Inuit communities on the North Coast of Labrador. Their shared commitment to collaboration and positive dialogue allowed us to achieve innovative solutions together that address the needs of all concerned.” Not to be outdone, Vale Canada’s operations in Sudbury, Ontario also received recognition for their
environmental performance, when The Mining Association of Canada presented Vale’s Sudbury Biodiversity Program an Environmental Excellence Award during the 2018 CIM Convention in Vancouver. “We are proud to be acknowledged for Vale’s biodiversity program in Sudbury,” said Lisa Lanteigne, environment manager for Vale’s Ontario operations. “The program has been successful because of a sustained commitment to community collaboration and an innovative approach to environmental stewardship. The program exemplifies one of our core company values – Prize Our Planet.” Vale’s biodiversity work in Sudbury focuses on regreening and reclamation efforts – transforming historically stressed lands and waterways back to their natural states after more than a
vale an iron grip on the market century of mining activities. To improve biodiversity within the community, Vale undertakes a number of activities, including: • Growing more than 300,000 trees annually in its greenhouse for planting throughout the City of Greater Sudbury. • Investing $250,000 and donating 50,000 tree seedlings annually to the City of Greater Sudbury’s Biodiversity Action Plan. • Promoting pollination by raising bees on its smelter property along Highway 55 in Sudbury and planting milkweed for monarch butterflies, which are great pollinators. • Seeding hundreds of acres each year by air through an aerial seeding program that has reclaimed approximately 8,000 acres since 1990. • Raising and releasing more than 100,000 fish to date into local waterways through a comprehensive fish-stocking program. “We congratulate Vale for their outstanding projects,” said Pierre Gratton, President and CEO, MAC. “They showcase what best practice looks like in our sector, whether it be spurring local economic development and entrepreneurship in communities where they operate or adopting innovative methods to restore mining areas back to nature.”
Coal
“At the Brucutu mine in Minas Gerais Vale has been trialling a system of autonomous trucks, controlled not by humans in the cab but by computer systems, GPS, radars and artificial intelligence”
Vale conducts its coal operations primarily in Mozambique, through Vale Moçambique. The company also has a minority interest in a Chinese coal producer. Of the two main types of coal, metallurgical coal is used in steel production, while thermal coal is used to generate heat and power in thermal power plants. Vale is ramping up both its metallurgical and thermal coal operations in Mozambique. The Moatize Mine has been producing coal since July 2011, and represents Vale’s biggest investment within the sector. One of the biggest challenges there is logistics, however, where Vale has invested in two railroads to connect to ports - Sena and Nacala Corridor – in order to transport the mine’s output.
The Nacala Corridor project will connect the Moatize Coal Mine to the Port of Nacala-a-Velha on the Nampula coast, with a transport capacity of 18 million metric tonnes of coal per year. This 912 kilometre long line includes a 237-kilometre stretch that passes through neighbouring Malawi. Already in operation, the 575-kilometre Sena Railroad connects Moatize to the Port of Beira, in the south of Mozambique, with a transport capacity of 6 million metric tonnes of coal per year. In 2017 Vale sold 50 per cent of its stake in the Nacala Logistics Corridor (NLC) and at the same time 15 per cent of its stake in the Moatize Mine to Japanese conglomerate Mitsui. In September this year Mozambique’s Cimentos de Maiaia awarded Vale the contract for its coal supply with an initial deal for 600tpa of thermal coal. “Every quarter we will take about 200t, and after a year of this contract we shall increase our capacity to use coal from Vale,” said the managing director of Cimentos de Maiaia, Chunjie Gou. The cement producer’s plant in Nacala Special Economic Zone was inaugurated three months ago and it is expected that the new coal supply agreement will reduce production costs. The coal will be delivered to the cement plant along the Nacala Logistics Corridor (CLN). The CLN is handling 1.3Mtpm, mainly for export. Since the line started operations some 30 months ago, it has exported over 20Mt of coal. When the line is in full operation, coal exports are expected to increase by 40 per cent. This will have a direct impact on the Moatize mine, which will be able to increase its production to 18 million tonnes a year, as well as reduce its transportation costs from mine to port. According to Vale, coal production at Moatize rose from 3.7 million tonnes in 2012 to 11.3 million tonnes in 2017.
Australia
Vale entered the Australian coal market in 2007 with the purchase of the Integra Coal Complex in New South Wales and Carborough Downs underground mine in central Queensland from AMCI Holdings. Operations at the Integra Coal complex were placed into care and maintenance in July 2014, however, as it was considered World Mining Magazine www.ogsmag.com

economically unviable in the prevailing market conditions. It was eventually sold to Glencore and Bloomfield Group in August 2015. Glencore took over Integra’s underground operations while Bloomfield acquired the open cut mine. The Integra colliery borders on separate coal assets already owned by Bloomfield and Glencore. It produced about 4.5 million tonnes of coal per year from both its underground and open cut mine before it was closed. Vale’s 90% stake in Carborough Downs was sold in December 2016 to Fitzroy Australia Resources, a subsidiary of the Group that originally sold it to Vale. It has also sold its Isaac Plains mine in the Bowen Basin to Stanmore Coal. After this round of disposals Vale retained three Australian coal assets; the Eagle Downs coking coal project which is under construction, the undeveloped Belvedere coal deposit and an early stage asset in the Galilee Basin, but it’s far from certain whether Vale is committed to developing its assets in Australia, given its emphasis on the ramp up in Mozambique. BHP spin-off South32 is allegedly close to acquiring Eagle Downs in partnership with Chinese steel producer Bauwu.
Copper
Copper is the third most used metal in the world, after iron and aluminium,

but is less significant at the moment, for Vale. While Vale Canada produces copper as a by-product of its nickel operations, in Brazil it operates two copper mines: Sossego and Salobo. Both operations are located in the Carajás
writing there are reports that Vale is on the verge of approving a $1 billion expansion of the mine. The project – known as Salobo 3 – is expected to take about three years to complete and will add about 50,000 tonnes to the open-pit mine’s current capacity of nearly 200,000 tonnes of copper per year.
“By unlocking the value of the cobalt by-product at Voisey’s Bay, Vale has found a way to resume substantive work on the underground project and support the market’s increasing demand for nickel, copper and cobalt”
In common with other leading mining companies, Vale is tweaking its strategy in favour of value, rather than volume, optimizing assets, selling non-core assets and investing in new technology and innovation. Commenting on the company’s 2017 results, CEO Fabio Schvartsman said: “Our 2017 performance shows remarkable cash generation and substantial net debt reduction as a result of improvements in price realization, strict discipline in capital allocation and slightly improved results from nickel and coal assets.” He concluded that, “2017 was a turning point for Vale. We started ambitious changes in efficiency, cost management and corporate governance. We laid the foundations for diversifying cash generation by improving the asset base we have today to reduce our dependency on iron ore. We aim to transform Vale into a predictable company.”

F
ounded in the 1970s as a metals and minerals marketing company, Glencore has grown by merger and acquisition to become one of the world’s largest resource traders and producers, with around 150 mining and metallurgical sites, oil production assets and agricultural facilities which source and market commodities to industrial consumers – such as steel-makers, vehicle manufacturers, power companies and processors of oil and food, the essential ingredients of modern life. Glencore turned in a solid financial performance in 2017, with adjusted EBITDA of $14.8 billion (up 44% from the year before) and net income attributable to equity holders increasing to $5.8 billion, from $1.4 billion in 2016. Even for a diversified multinational resource company, commodity differentiation is becoming increasingly

important. Global automobile OEMs are investing $billions in electric vehicles, so Glencore is developing its commodity mix in recognition of the importance of copper, nickel and cobalt to the modern world. Glencore commissioned an independent study last year to gauge the incremental demand for these commodities, based on the Electric Vehicles Initiative scenario of 30% electric vehicle market share by 2030. The findings suggested that an additional 4.1Mt of copper, 1.1Mt of nickel and 314kt of cobalt would be required.
Copper and cobalt in Africa
At the time of writing, the ink is barely dry on Glencore’s results for the second quarter of 2018. The company reported that its own sourced copper production of 696,200 tonnes for the first half year
was 53,300 tonnes (8%) higher than H1 2017 and cobalt production of 16,700 tonnes was an impressive 4,000 tonnes (31%) higher, reflecting the restart/ ramp-up of Katanga. The Katanga complex in the Democratic Republic of Congo (of which Glencore holds a majority share) includes the Kamoto underground mine, KOV open pit mine, the Kamoto concentrator and Luilu metallurgical plant for the onsite production of refined copper and cobalt, as well as a number of other mines and plants. Katanga has the potential to become Africa’s largest copper producer and the world’s largest cobalt producer, but in September 2015 the board of Katanga confirmed the suspension of copper and cobalt production for 18 months, pending the completion of a whole ore leach (WOL) processing project. Phase
glencore commodities for the modern world One of the project was commissioned in December 2017, with 2,200 tonnes of copper cathode produced by the end of the month. Full commissioning of phase two of the WOL project is expected to commence in Q4 2018. Another centre of investment for Glencore is Zambia, where it is majority owner of the Mopani Copper Mine. In 2015 the decision was taken to restructure production at the mine, to deliver more sustainable growth in the long term. Mopani is also an integrated copper and cobalt producer with operations consisting of four underground mines, a concentrator and a cobalt plant in the town of Kitwe and an underground mine, concentrator, smelter and refinery in the town of Mufulira. The company also has four SXEW plants (solvent extraction and electrowinning), two at Mufulira and two at Nkana. Since 2014, Mopani has invested over $1 billion in site expansions and upgrades to extend the life of mine by a further 25-30 years. In March 2017, Mopani chairman Moses Chilangwa spoke about a further US$1.3 billion investment in capital projects that include sinking and equipping three new shafts, which are scheduled to come online by the end of 2018. These will more than double Mopani’s mining output from the current 3.8 million tonnes of copper ore per annum to 9 million tonnes by 2020.
World copper
“Katanga has the potential to become Africa’s largest copper producer and the world’s largest cobalt producer”
As well as Africa, Glencore has copper assets in North and South America and Australia. The Collahuasi mine in Chile produces copper concentrate and cathodes. One of the world’s largest copper operations, Collahuasi’s deposits are located on the plateau of northern Chile’s Atacama Desert, 4,400 metres above sea level. Glencore and Anglo American each own 44 per cent, with a Japanese consortium owning the remaining 12 per cent. Glencore’s share of copper production in 2017 was 230,500 tonnes, up 3% on 2016, mainly reflecting marginally improved ore grades and consistently strong milling performance. In Peru, Glencore owns a 33.75% interest in the Antamina open pit copper and zinc mine, 4,300 metres
above sea level. Antamina’s concentrator is considered to be one of the world’s largest polymetallic processing plants, treating ores containing copper, zinc, molybdenum, silver and lead. Glencore’s share of copper production in 2017 was 142,600 tonnes, in line with 2016, and the share of zinc production was 128,100 tonnes, an increase of 92% on 2016, reflecting the higher proportion of copper/zinc ores being mined, and the inherent nature of the Antamina deposit. Glencore’s Antapaccay copper operation is located in Espinar Province in southern Peru. Acquired in 2013 through the merger with Xstrata, the operation includes an open pit copper mine and processing facilities in addition to port loading and facilities at Matarani. Altonorte is a custom copper smelting operation located near the port of Antofagasta in northern Chile. The Glencore operation has the capacity to process 1.6 million tonnes of copper concentrate from third parties per year. Also in Chile is Punitaqui, a copper mine and concentrator acquired by Glencore as a brownfield development in early 2010. Glencore also has a 50% controlling stake in Alumbrera, an open pit copper/ gold mine in the Catamarca Province of northwest Argentina, but this is now coming to the end of its life. El Pachón is a copper project located in Argentina’s San Juan Province, five kilometres from the Chilean border, which is yet to be developed. In Australia, the company’s North Queensland copper mining and processing operations include the Mount Isa Mines complex, Ernest Henry Mining and the copper refinery in Townsville. Ernest Henry Mining is a copper and gold mining and processing operation located near Cloncurry in northwest Queensland. The operation began production in 1998 as an open pit mine and in 2011 transitioned to underground mining as part of a $589 million life of mine extension project. Copper ore is processed at the on-site concentrator and trucked to Mount Isa Mines for smelting into copper anode. In 2016 a 30 per cent stake in Ernest Henry was sold to Evolution Mining.

Mines remains one of Australia’s largest industrial complexes, with two separate mining and processing streams, copper and zinc-lead-silver. The Mount Isa copper operations host two underground mines, including Australia’s deepest underground copper mine at 1,900 metres. Ore is processed and smelted on site before being transported via rail to the copper refinery and port operations in Townsville for further processing and export.
Zinc
Glencore mines and processes zinc and lead ores in Australia, South America, Kazakhstan and Canada. It also smelts and refines zinc and lead at processing operations in Australia, Canada, Spain, Italy, Germany, the UK and Kazakhstan. Through its marketing division, Glencore also sells zinc and lead concentrates and by-products such as sulphuric acid, marketing zinc and lead not only from its own facilities, but also from third-party producers. The company also sells gold and silver,
“Operating since 1924, Mount Isa Mines remains one of Australia’s largest industrial complexes, with two separate mining and processing streams, copper and zinc-lead-silver”
which are typically mined together with zinc and lead ores. Over half of Glencore’s total zinc and lead reserves and resources are located in Australia, where Mount Isa Mines and McArthur River Mine host the world’s No.1 and No.2 zinc resource bases. The North Queensland zinc operations include an integrated supply chain comprising mining, processing, transport and logistics, as well as port facilities. The zinc operations at Mount Isa include the George Fisher underground mine, zinc-lead concentrator, zinc-lead filter plant and lead smelter. Glencore also owns the high-grade Lady Loretta underground mine near Mount Isa, where production was temporarily suspended in 2015 but has recently recommenced, with Redpath Australia contracted to run the mine for its remaining six year lifespan. McArthur River Mine (MRM) in Australia’s Northern Territory is around 970 kilometres south-east of Darwin and includes an open cut mine and processing stream. MRM currently World Mining Magazine www.ogsmag.com

produces bulk concentrates and zinc and lead concentrates, which are transported by road from the mine site to Glencore’s Bing Bong Loading Facility on the Gulf of Carpentaria. In 2017, Glencore’s own sourced zinc production of 1,090,200 tonnes was in line with 2016, as a step-up in Antamina zinc production was offset by the disposals of its African mines to Trevali Mining, and lower production at Mount Isa.
Nickel
Glencore’s nickel business produces some of the world’s purest nickel, ferronickel and cobalt. Around twothirds of all nickel is used in the production of stainless steel. The remainder is used for applications including super-alloys, batteries and electroplating. Glencore is one of Australia’s largest nickel and cobalt producers, and with more than 30 years of nickel reserves, it has one of the longest life of mine reserves. Murrin Murrin is a worldclass hydrometallurgical nickel project
located between Leonora and Laverton in the northeastern Goldfields region of Western Australia. Operated by Minara Resources, wholly owned by Glencore, Murrin Murrin uses high pressure acid leach technology to recover nickel and cobalt from laterite ore. Processed nickel and cobalt is transported via rail to Kwinana, south of Perth, for export to customers worldwide. In Canada, Glencore’s Sudbury Integrated Nickel Operations (Sudbury INO) include Exploration, two underground mines (Nickel Rim South and Fraser), Strathcona Mill and the Sudbury Smelter. The company has been mining nickel-copper ores in the Sudbury area of northern Ontario since 1928. The facilities are spread throughout the 60 kilometre-long, oval-shaped geological formation known as the Sudbury basin. Nickel and copper are the primary metals but cobalt and precious metals, such as gold, silver, platinum and palladium are also produced. Also in Canada, in the far north of Quebec, is the Raglan mine property,
which has four underground mines and associated infrastructure, with highgrade ore deposits of nickel and copper spanning the nearly 70km property. The ore extracted from Raglan Mine is crushed, ground and processed on-site to produce a nickel-copper concentrate, which is then sent to the Sudbury Smelter for further processing. The concentrator treats approximately 1.3 million tonnes of ore a year, resulting in more than 30,000 tonnes of nickel-inconcentrate annually. Raglan Mine’s current operations, which began in 1997, are expected to gradually cease as from 2020, but the Sivumut Project is being developed to extend the life of the mine for an additional 20 plus years. In Norway Glencore owns and operates Nikkelverk, a low-cost, nickel refinery and sulphuric acid plant in Kristiansand, which it acquired when it merged with Xstrata in 2013. Nickel has been produced here for over 100 years. The plant ranks among the lowest-cost nickel refineries in the western world and produces high purity nickel in the World Mining Magazine www.ogsmag.com

form of cathode and crown products. Glencore also has an interest in Koniambo Nickel, a ferronickel mine and processing plant in New Caledonia. The operation is a JV partnership between Glencore (49%) and Societe Minière du Sud Pacifique SMSP (51%). It includes a pyrometallurgical nickel smelter, power station and 11km overland conveyor, seawater desalination plant and other infrastructure. Own sourced nickel production of 62,200 tonnes in 2017 was 11,000 tonnes (21%) higher than H1 2017, reflecting Koniambo’s second processing line entering production and the scheduled statutory shutdown at Murrin.
Coal
While Glencore has its eyes set on the future with its interests in copper, nickel and cobalt, it has not turned its back on a more traditional commodity – coal. Global demand for seaborne thermal coal grew 3.7% during 2017. On the supply side, Glencore’s coal production of 121 million tonnes was 3% down on 2016, as reductions associated with industrial action and adverse weather events were mostly offset by productivity improvements and the company’s higher equity share in certain mines. Glencore has interests in coal
“In May this year Glencore acquired a 49% interest in the Hunter Valley Operations (HVO) coal mine in NSW, forming a joint venture with Yancoal”
mines in Australia, South Africa (the Goedgevonden complex, Izimbiqa coal, Tweefontein complex and iMpunzi complex) and Colombia (Cerrejón and Prodeco, which includes the La Jagua and Calenturitas mines). In 2017, production of Australian thermal and semi-soft of 60.6 million tonnes was 1.7 million tonnes (3%) down on 2016, as higher equity ownership of the Newlands and Collinsville mines, and planned rampups (notably Rolleston) and production efficiencies across the board were offset by planned mine closures and the impact of industrial action. South African thermal production of 28.7 million tonnes was in line with 2016, as improved operating performances at the main mine complexes were offset by planned closures of smaller mines. In Colombia, Prodeco produced 14.6 million tonnes, 2.7 million tonnes (16%) lower than in 2016, initially due to the impact of severe wet weather and later, as a result of a geotechnical event, with productivity adversely affected by the necessary workarounds. At 10.6 million tonnes, Glencore’s share of production at Cerrejón was in line with 2016, as the easement of some restrictions related to dust emissions in 2016 was offset by the disruption caused by unusually heavy rainfall. World Mining Magazine www.ogsmag.com

Glencore’s interest in coal began with the acquisition in 1998 of the Cumnock and Mount Owen coal mines in Australia, and it is now one of Australia’s largest coal producers. The Cumnock mine is now part of Glencore’s Ravensworth Operations in New South Wales. Glencore is the largest coal producer in New South Wales, employing around 4,400 people in eight mining complexes across three coalfields: Hunter Valley, Western Districts and Southern Districts. Coal is exported from the Port of Newcastle and also from Port Kembla. Ravensworth open cut mine is located in the NSW Hunter Valley, alongside a coal handling and preparation plant. The mine is a joint venture between Itochu 10% and Glencore 90%. The CHPP assets are owned by the JV but operated by Glencore. The Mt Owen Complex consists of Mt Owen, Ravensworth East and Glendell open cut coal mines, owned and managed by Mt Owen Pty Limited, a wholly owned subsidiary of Glencore. The integration of these adjacent operations enables all sites to utilise existing infrastructure and coal handling facilities at Mt Owen Mine.

“In March this year Glencore agreed to buy Rio Tinto’s 82% interest in the Hail Creek coal mine, as well as its 71.2% interest in the Valeria coal resource in central Queensland for a total cash consideration of US$1.7 billion”
Fifteen kilometres south west of Singleton is the Bulga Complex, which includes Bulga open cut, Bulga underground operations and the coal handling and preparation plant. Bulga open cut and Bulga underground are managed by Glencore, which is also the majority shareholder, via a somewhat complex ownership structure. Mangoola open cut is in the Upper Hunter Valley, 20 kilometres west of Muswellbrook and approximately 10 kilometres north of the township of Denman. A relatively new mine, the 100% Glencore owned Mangoola open cut commenced production in November 2010, and won the Australian Mine of the Year award in 2013 in recognition of its water, noise, air and dust management and its community engagement. More recently, in May this year Glencore completed the acquisition of a 49% interest in the Hunter Valley Operations (HVO) coal mine in NSW, following the receipt of regulatory approvals. The HVO is a joint venture with Yancoal, which owns a 51% stake. Away from the Hunter Valley, Tahmoor Mine is an underground coal mining operation situated in the
glencore commodities for the modern world
Southern Highlands Region of New South Wales, approximately 75km south west of Sydney. Glencore had planned to close the Tahmoor mine in 2018, mainly because of its isolation from the company’s Hunter Valley-based operations, but a resurgence in the price of coking coal allowed the mine to be kept open. It was sold to British industrialist Sanjeev Gupta’s GFG Alliance earlier this year. The Ulan Mine Complex is one of the most established coal mining operations in the western coalfields of New South Wales. A joint venture between Glencore (90%) and Mitsubishi Development (10%), mining operations consist of two underground mines and an open cut. In 2015 Glencore secured approval to expand the underground mine to extract another 13 million tonnes of coal and extend the mine’s operational life by another two years, until 2033. In Queensland Glencore employs over 2,600 people, managing the production of more than 38 million tonnes of saleable thermal and coking coal. Collinsville open cut is Queensland’s oldest coal mine, having operated as an underground or open cut mine for almost 100 years. It was
recently operating as a joint venture between Glencore Coal Queensland (55%), Itochu Coal Resources (35%) and Sumitomo (10%), but Glencore bought out its joint venture partners in Collinsville in September 2016, along with the Newlands coal operation. Glencore also owns a 55% share in Oaky Creek Coal in Central Queensland, which has two underground operations and a coal preparation plant. Open cut operations ceased in December 2006. The underground operations are modern, state-of-the art longwall operations with associated development works. Coal is exported through eastern seaports in Mackay and Gladstone to Japan, Asia, Europe, North Africa and South America. In March this year Glencore agreed to buy Rio Tinto’s 82% interest in the Hail Creek coal mine and adjacent coal resources, as well as its 71.2% interest in the Valeria coal resource in central Queensland for a total cash consideration of US$1.7 billion. Hail Creek is a large-scale, long-life and low-cost mine producing two-thirds premium quality hard coking coal and one-third thermal coal for export. Located 75 miles southwest of Mackay,
in 2017 Hail Creek produced about 9.4 million tonnes of coal for export from the Dalrymple Bay Coal Terminal, comprising 5.25Mt of hard coking coal and 4.13Mt of thermal coal. As at 31 December 2017, Hail Creek had resources of 794 million tonnes with proven and probable reserves of 142 million tonnes. In 2017, Glencore outperformed all its UK-listed major diversified mining peers. Copper and cobalt are expected to play important roles across the value chain of the energy and mobility evolution, from power generation and distribution, to energy storage and vehicles, and coal is not going away anytime soon. Signing off the 2017 financial report, Glencore’s chief executive officer, Ivan Glasenberg, commented: “Our performance in 2017 was our strongest on record, driven by our leading marketing and industrial asset businesses. We look to the future with confidence. We believe our unrivalled positioning in ‘Tier 1’ commodities and ‘Tier 1’ assets will continue to create compelling value for all stakeholders.” World Mining Magazine

Barrick and Randgold merge into world’s largest gold miner B arrick Gold has agreed to buy Randgold Resources in an all-stock deal to create the world’s largest gold producer, worth a combined $18 billion. The merged company will hold five of the world’s top 10 tier one gold assets and the lowest total cash cost among the sector’s leading operators. Following completion of the deal, Barrick shareholders will own two thirds of the enlarged group, with Randgold shareholders owning the remainder. The merger, which will combine Randgold’s African mines with Barrick’s holdings in the Americas, values Randgold at $6.5 billion. The new company will continue to trade as Barrick, keeping its listings on the Toronto and New York stock exchanges, while Randgold will be delisted from the London Stock Exchange. Commenting on the deal in a conference call, Barrick
“Randgold has the agility and swift-footedness of a younger and smaller company, much like Barrick in its early years” Chairman John Thornton said, “Randgold has the agility and swift-footedness of a younger and smaller company, much like Barrick in its early years, while Barrick has the infrastructure and global reach of a large corporate company.” The merged company will be headed by Randgold’s longterm CEO Mark Bristow as president and chief executive, with
chief financial officer Graham Shuttleworth moving with him. Thornton will be executive chairman. Responding to criticism of the gold mining industry for its short-term focus, undisciplined growth and poor returns on invested capital, Bristow promised change. “The merged company will be very different,” he said. “Its goal will be to deliver sector leading returns, and in order to achieve this, we will need to take a very critical view of our asset base and how we run our business, and be prepared to make tough decisions.” The merger is expected to close in the first quarter of 2019 after all conditions have been met.

Under the terms of the transaction, former shareholders of Arizona Mining were entitled to C$6.20 in cash for each common share held. The transaction consideration of US$1.3 billion (C$1.8 billion) implies a total equity value for Arizona Mining of US$1.6 billion (C$2.1 billion). With the acquisition now complete, Arizona Mining was delisted from the Toronto Stock Exchange on 10 August 2018. Arizona Mining is the owner of the Hermosa Project, containing the high
grade base metals Taylor deposit, the Central zinc, manganese and silver oxide resource and an extensive, highly prospective land package with potential for discovery of polymetallic and copper mineralisation. South32 has been a major shareholder in Arizona Mining since May 2017. “The acquisition of Arizona Mining adds to our portfolio one of the most exciting base metal projects in the industry,” said Graham Kerr, CEO of South32. “Our deep understanding of the high-grade Hermosa project and surrounding land package, together with our extensive experience at Cannington, positions us well to bring the project to development and deliver
significant value to our shareholders.” The project is located close to key infrastructure in an attractive mining jurisdiction. A preliminary economic assessment completed by Arizona Mining in January 2018 indicated that this low cost, long life project has the potential to deliver a very high internal rate of return on investment.

Transition options high grade gold opportunity in Nova Scotia
T
ransition Metals Corp has agreed to acquire a 100% interest in the Highland Gold property in the Cape Breton Highlands of Nova Scotia. The property covers an extensive cluster of high grade gold occurrences that have seen very limited exploration. “We think the potential for the area to host large deposits of gold is strongly supported by the historical, highly
“Rocks of similar age and formation are known to host significant gold deposits” anomalous results coming from stream sediments, tills, soil and bedrock samples,” said CEO Scott McLean. “Rocks of similar age and formation are known to host significant gold deposits in the Carolinas, Newfoundland, Ireland and Scotland. Cape Breton has an overlooked district scale gold potential that should be of interest to major gold producers looking for
new opportunities. We plan to initiate exploration work this fall.” Transition can earn a 100% interest in the property by spending $1.5 million and making payments of $170,000 in cash and $175,000 in shares to the vendor over a five year period. The vendor would retain a 2% net smelter return royalty (NSR) with Transition retaining the right to buy back 1% NSR for $1.25 million. Work planned by the company this fall includes till and soil sampling, a high resolution airborne magnetic/ conductivity survey, and reverse circulation drilling. Additionally, the Nova Scotia Mineral Resources Development Fund will provide up to $95,000 in exploration funding assistance which will help the company offset some of its costs. The government of Nova Scotia’s funding program is designed to assist prospectors, exploration companies and researchers in the search for new discoveries, to advance projects closer to production, and to attract investment into the Province.
Heron’s Woodlawn project goes underground

eron Resources has commenced underground activities at its Woodlawn zinc-copper project in New South Wales, Australia. The company signed a 4-year underground mining contract with Pybar Mining Services in February this year. Pybar has commenced mining activities including the ground support of the box cut walls and the first portal blast of the decline. Completion of this activity signifies the commencement of underground operations. “It is very pleasing to see the start of underground activities at Woodlawn,” said Heron managing director, Wayne Taylor. “Exploration over the last four
years has defined a high-grade, highquality resource and reserve position, and the access which has now
commenced will enable us to deliver underground ore into the processing plant in 2019. “Once underground, our geological
team will focus on further expanding the known mineralised positions to build upon the excellent and costeffective work they have undertaken to date. Elsewhere on site, I am pleased to report that good progress continues to be made with all aspects of the build, and that works remain on schedule for the commencement of commissioning by the end of the year.” The company said in a statement that the overall project was almost three-quarters complete. Concrete and earthworks were ‘substantially completed’, with offsite fabrication 92% complete and equipment purchase 98% complete. World Mining Magazine www.ogsmag.com

Hancock and Rio Tinto open new Pilbara iron ore mine J
oint venture partners Hancock Prospecting and Rio Tinto have opened the Baby Hope iron ore mine, a fourth Hope Downs operation in the Pilbara region of Western Australia. Hope Downs already comprises three major open pit mines – Hope 1 North, Hope 1 South and Hope 4 – producing high-grade lump and fines products. Baby Hope is around four kilometres south-west of the Hope Downs 1 South deposit, and immediately north of the Lang Hancock rail line. All necessary government and environmental approvals for Baby Hope have been secured. The joint venture partners also approved an investment in greater automation. The JV intends to retrofit 28 haul trucks at the Hope Downs
“Hope Downs was named after Gina Rinehart’s mother” 1 mine with autonomous haulage system (AHS) technology and three production drills at the Hope Downs 4 mine with autonomous drilling system (ADS) technology by 2020. The automation is expected to bring productivity and safety gains to the mine’s existing fleet. Hope Downs 1 and 4 produced 46.9 million tonnes (Mt) of iron ore last year, representing one of Australia’s largest and most successful iron ore projects in
the lower cost quartile. The equal joint venture was created when Rio Tinto bought in to Hope Downs in 2005, after Hancock completed a bankable feasibility study and exploration. Hope Downs was named after Hope Hancock, the mother of Gina Rinehart, executive chairman of Hancock Prospecting, and was developed by Rinehart’s father, Lang Hancock, who uncovered major iron ore deposits in the Pilbara.
Official reopening of the Century Zinc Mine N

Among the guests were Federal Minister for Resources and Northern Australia, Senator the Honourable Matt Canavan, along with the Honourable Bob Katter MP, local mayors and representatives of the Waanyi community. Guests on the site visit were treated to an inspection of the tailings reprocessing operations, providing a close-up viewing of Australia’s largest ever hydraulic mining operation.
Previous mine owner MMG ceased processing operations in early 2016 following depletion of the ore reserves, creating an opportunity for a focused
junior to exploit its remaining mineral assets, including over 2,200,000t of JORC compliant zinc metal equivalent resources within mineralised tailings. Phase 1 operations at the Century Mine began last month, involving the mining and reprocessing of 8Mtpa of tailings and production of zinc concentrate to be exported via the company’s port facility at Karumba.

barrick gold a miracle never to be repeated
P
eter Munk, the iconic Canadian entrepreneur and philanthropist who founded Barrick Gold, died on 28 March 2018, at the age of 90. He was a rare individual. Born to be a businessman, Munk employed fellow students to sell Christmas trees in Toronto while still an undergraduate himself. Munk won design awards in the 1950s for his custom-made hi-fi equipment, before diversifying into a hotel empire in the South Pacific, then having a little dabble in oil and gas. In his late-fifties, when others might be thinking of early retirement, Munk bought a gold mine. He then grew Barrick into the world’s largest gold mining company in less than 25 years. As he said himself, Barrick is “a miracle not to be repeated. It will go down in the annals of business history.” In 1986, the purchase of the Goldstrike Mine in Nevada set Barrick on a
trajectory to international expansion, with the subsequent acquisition of mines in South America, Africa and the Australia Pacific region seeing it become, for a while, the largest gold producer in the world. But largest is not the end game for Barrick Gold. It simply wants to be the best. Over the past three years, the company has optimized its portfolio by divesting high-cost, non-core operations. The proceeds of these divestments have been used to reduce total debt by more than 50 per cent, from $13.1 billion at the end of 2014, to
$6.4 billion at the end of 2017. Although it still has assets on other continents, the company’s portfolio is now focused on high-margin, long-life gold operations in core districts throughout the Americas. The overriding objective continues to be growing free cash flow per share over the long term. To this end, Barrick has put together a business plan that involves the pursuit of three strategic goals over the next five years. The first is to drive industry-leading margins through operational excellence and consistent execution. The second is World Mining Magazine www.ogsmag.com
73
to manage its portfolio and allocate capital with discipline and rigour, and the third is to leverage top talent and the company’s distinctive partnership culture as competitive advantages, building partnerships based on trust with host governments, local communities, NGOs, indigenous people, and others.
Operational update
Barrick is constantly pushing to reduce costs by being the best for productivity and efficiency. While it may produce fewer ounces than in recent years, it generates significantly more free cash flow per share. In 2017, Barrick’s operations produced 5.32 million ounces of gold, at a cost of sales of $794 per ounce, with a particularly strong performance from Barrick Nevada. This compares to production of 5.52 million ounces of gold in 2016, at a cost of sales of $798 per ounce. Lower production in 2017 primarily reflects the sale of 50 per cent of the Veladero mine on 30 June, and lower production from Acacia as a result of Tanzania’s concentrate export ban. Barrick outlined its strategic

framework in its 2017 annual report. Operational excellence, it said, would be driven “through a continuous cycle of optimization, pushing our mines to achieve greater levels of efficiency and productivity, while working to mitigate increasing costs associated with more complex ore types and a shift to more underground mining. This will be aided by investments in digital technology and innovation, which will allow us to identify and accelerate further operational improvements across our portfolio.” Barrick Gold’s breadth of operations spans the globe. Its key sites include the Cortez District and Goldstrike in Nevada, Hemlo in Ontario, Pueblo Viejo in the Dominican Republic, Lagunas Norte in Peru, and Kalgoorlie in Western Australia, a 50/50 joint venture with Newmont Gold. Barrick Nevada is an integrated gold mining operation that combines the Cortez and Goldstrike properties. The operation employs both open pit and underground mining methods, and hosts a range of processing facilities including heap leaching, roasting, autoclaving, conventional leaching and
barrick gold a miracle never to be repeated thiosulfate (cyanide-free) leaching. Pueblo Viejo is located in the Dominican Republic, approximately 60 miles northwest of the capital city of Santo Domingo, and is operated by the Pueblo Viejo Dominicana Corporation (PVDC), a joint venture between Barrick (60%) and Goldcorp (40%). Barrick’s share of gold production in 2017 was 650,000 ounces, at a cost of sales of $699 per ounce. Gold production in 2018 is forecast to be 585,000-615,000 ounces (Barrick’s share). As of 31 December 2017, Barrick’s share of proven and probable gold reserves at Pueblo Viejo was 7.2 million ounces. In May this year Barrick announced the conversion of the Pueblo Viejo power plant from heavy fuel oil to natural gas, which is expected to reduce the mine’s average cost of sales by approximately $54 per ounce over the life of the mine, supported in part by higher margins on the sale of excess power to the national energy grid. Barrick is currently advancing prefeasibility-level studies for a plant expansion at the Pueblo Viejo mine that has the potential to significantly increase throughput at the operation. Conversion of the power plant to natural gas is likely to strengthen the economics of the project. The Hemlo property in Canada consists of Williams, an underground and open pit mine, located approximately 220 miles east of Thunder Bay, Ontario. Previous underground production also came from the Golden Giant and David Bell mines which are now closed. Hemlo produced 196,000 ounces of gold in 2017. Proven and probable mineral reserves as of 31 December 2017 were 1.77 million ounces of gold. Underground mineral reserves at the Williams Mine are projected to sustain underground operations until 2021, while open pit mineral reserves have the potential to support operations until 2027. The Veladero mine in the San Juan Province of Argentina is located at elevations of 4,000 to 4,850 meters above sea level, approximately 230 miles northwest of the city of San Juan. Operations include open pit mining of gold-silver ore, two-stage crushing, and extraction of precious metals using
valley-fill heap leaching and MerrillCrowe recovery. In April 2017 Barrick sold a 50 per cent interest in the Veladero mine to Shandong Gold Mining Co for $960 million. The formation of a 50/50 joint venture at Veladero is the first of three steps outlined in a strategic cooperation agreement. In keeping with the second step in the agreement, the two companies formed a working group to explore the joint development of the Pascua-Lama deposit. As a third step, Barrick and Shandong will evaluate additional investment opportunities on the highly prospective El Indio Gold Belt on the border of Argentina and Chile. The Kalgoorlie operation in Australia consists primarily of the Super Pit openpit mine, located along the Golden Mile ore bodies which were previously mined from underground. The mine is located adjacent to the town of Kalgoorlie, approximately 350 miles east of Perth, Western Australia. The mine is a 50/50 joint venture with Newmont Mining Corporation. Kalgoorlie is an open-pit, truck-andloader operation. Barrick’s share of gold production in 2017 was 368,000 ounces. Its share of proven and probable reserves as of 31 December 2017 was 3.858 million ounces of gold (99.0 million tonnes, grading 1.21 grams per tonne), and its share of gold production in 2018 is expected to be 390,000-440,000 ounces. The Porgera Joint Venture is an open
pit and underground gold mine situated at an altitude of 2,200-2,700 meters in the Enga Province of Papua New Guinea. The operation is roughly 80 miles west of Mount Hagen and 375 miles northwest of the capital, Port Moresby. Barrick (Niugini) Ltd. is the 95% owner of the Porgera Joint Venture and is the manager of the operation. Barrick Gold Corporation and Zijin Mining Group each own 50% of Barrick (Niugini) Ltd. The remaining 5% interest in the Porgera Joint Venture is held by Mineral Resources Enga and is divided between the Enga Provincial government (2.5%) and local landowners (2.5%). Barrick’s share of gold production in 2017 was 235,000 ounces, and its share of proven and probable mineral reserves at 31 December was 2.0 million ounces of gold (13.3 million tonnes, grading 4.78 grams per tonne). In 2018, Barrick’s share of gold production is expected to be 230,000-255,000 ounces. Although predominantly focused on gold, Barrick has some copper interests, too. The Jabal Sayid copper operation is located 200 miles northeast of Jeddah in the Kingdom of Saudi Arabia. It’s a 50/50 joint venture operation with Saudi Arabian mining company Ma’aden. The first shipment of copper concentrate was made in December 2015, and the mine commenced commercial production in July 2016. Jabal Sayid produced 43 million pounds of copper in 2017 (Barrick’s share), at a cost of sales of $1.90 per World Mining Magazine www.ogsmag.com
75
pound, and all-in sustaining costs of $2.30 per pound. Barrick’s share of proven and probable copper reserves at the end of 2017 was 626 million pounds (11.8 million tonnes, grading 2.40%). Its share of production in 2018 is anticipated to be 40-55 million pounds. The Lumwana copper mine in Zambia sits in one of the most prospective copper regions in the world. Lumwana ore, which is predominantly sulphide, is treated through a conventional sulphide flotation plant, producing copper concentrate for smelting. Lumwana produced 256 million pounds of copper in 2017, and had proven and probable copper reserves of 5.014 billion pounds as of 31 December 2017 (401 million tonnes, grading 0.567%). Production in 2018 is anticipated to be 230-265 million pounds.
Projects update
Barrick continues to advance a pipeline of high-confidence projects at or near its existing operations, with the potential to contribute more than one million ounces of annual production at costs well below its current portfolio average. Goldrush has the potential to become Barrick’s newest underground mine in Nevada, with first production expected as early as 2021, and sustained production by 2023. The prefeasibility study estimated average production of approximately 450,000 ounces of gold per year, at an average cost of sales of $800 per ounce, and average all-in
World Mining Magazine www.ogsmag.com

sustaining costs of $665 per ounce. Goldrush currently has proven and probable gold reserves of 1.5 million ounces, and measured and indicated gold resources of 9.4 million ounces, with significant potential to identify additional resources once underground access to drill the deposit is established. Ongoing surface drilling in the Red Hill zone of the deposit in 2018 is also expected to support additional resource conversion. The Deep South project at Cortez will expand underground mining below currently permitted levels, and is on track to contribute average underground production of more than 300,000 ounces per year between 2022 and 2026. The prefeasibility study anticipated a cost of sales of $840 per ounce for mining in the Deep South zone. Optimization work has identified a number of opportunities to reduce these costs, including through the use of autonomous loading with a smart conveyance system, compared to a traditional conveyor system contemplated in the prefeasibility study. Permitting was initiated in 2016 and is expected to take approximately three to four years, including the preparation of an Environmental Impact Statement. A Record of Decision on the EIS is expected in the second half of 2019, followed by two years of construction, with initial production from Deep South in 2022. The construction of a third shaft at Turquoise Ridge in Nevada has the
potential to roughly double annual production to more than 500,000 ounces per year. The contract for shaft sinking was awarded to Thyssen Mining in the first quarter of 2018 and procurement of long lead-time items has begun. Initial production from the new shaft is expected to start in 2022, with sustained production from 2023. At 15.56 grams per tonne, Turquoise Ridge has the highest average reserve grade in the company’s operating portfolio, and among the highest in the gold industry. The Lagunas Norte operation in Peru produced 387,000 ounces of gold in 2017, at a cost of sales of $617 per ounce. Production in 2018 is anticipated to be 230,000-270,000 ounces of gold, at a cost of sales of $780-$910 per ounce. Proven and probable gold reserves as of 31 December 2017 were 4.0 million ounces. Barrick is evaluating a phased project to extend the life of the Lagunas Norte mine by approximately 10 years. The first phase would be to install grinding and carbon-in-leach processing, and the second would involve installation of a flotation and pressure oxidation circuit, allowing the company to optimize the timing of capital expenditures. Barrick also maintains a portfolio of greenfield projects that represent significant long-term value. Donlin Gold in Alaska, a 50:50 joint venture with NOVAGOLD, contains 19.5 million ounces of measured and indicated gold resources (Barrick’s share). Barrick is working in
barrick gold a miracle never to be repeated collaboration with NOVAGOLD to optimize the project, including the potential for staged development, while reducing upfront capital and mitigating development risk. The final Environmental Impact Statement was published by the US Army Corps of Engineers in April 2018, with a Record of Decision expected in the second half of the year. The company anticipates decisions on most of the federal and state permits by early 2019.
Exploration update
“In May this year Barrick announced the conversion of the Pueblo Viejo power plant from heavy fuel oil to natural gas, which is expected to reduce the mine’s average cost of sales by approximately $54 per ounce over the life of the mine”
Barrick has a track record of creating value through exploration. Approximately 80 per cent of Barrick’s total exploration budget of $185-$225 million is allocated to the Americas and is spread between high-quality brownfield projects, greenfield exploration, and emerging discoveries that have the potential to become profitable mines. The company added 8.0 million ounces of gold reserves in 2017 through mine exploration drilling, proving that even well established operations can still yield exploration results. In these cases, the discoveries can often be quickly incorporated into mine plans, driving improvements in production, cash flow, and earnings. Barrick drilled more than 18,000 metres at Goldstrike in 2017, adding 1.3 million ounces of proven and probable gold reserves, and 1.5 million ounces of measured and indicated resources. This drilling identified a host of high-grade extensions to known lodes that will be a focus for further drilling in 2018.
Proven and probable gold reserves were also increased by 2.1 million ounces at Turquoise Ridge. Other significant additions included 1.4 million ounces at Cortez, 1.3 million ounces at Goldstrike, 397,000 ounces at Hemlo and 392,000 ounces at Lagunas Norte. Over 9.0 million ounces of measured and indicated gold resources were added as a result of the formation of Norte Abierto (a 50/50 joint venture with Goldcorp in Chile), net of resources divested at Cerro Casale and Veladero. Roughly 14.0 million ounces of measured and indicated resources were also added as a result of the reclassification of Pascua-Lama reserves to resources. Barrick’s 2018 greenfield exploration program will focus on the prolific Cortez district in Nevada and the Frontera District on the El Indio Belt in Argentina and Chile. The Fourmile exploration project, just north of the Goldrush deposit, is the focus of attention in Nevada. Drilling to date has intersected mineralization well above the average grade of the measured and indicated resources at Goldrush. Barrick is increasingly confident that Fourmile and Goldrush form part of a seven-kilometre-long mineralized system, similar in length to the mineralization at Goldstrike. The company plans to drill 24 holes at Fourmile in 2018. The Alturas project, located in Chile on the El Indio Belt, is a Barrick greenfield discovery with 6.8 million ounces of inferred gold resources as of 31 December 2017. Following completion of a scoping study for a conventional open pit heap leach operation at Alturas, Barrick is now carrying out further studies to evaluate potential enhancements to the project design, while undertaking additional drilling to improve orebody knowledge and grades. The company has also cultivated partnerships with a number of junior exploration and development companies as it seeks to identify potential new core mineral districts. These partnerships are with ATAC at the Orion project in the Yukon, with Osisko at the Kan property in northern Québec, and with Premier Gold at Cove McCoy in Nevada.

barrick gold a miracle never to be repeated Digital future
As technology advances, new ideas arrive and new ways of working begin to take hold, even in the mining industry, not renowned as an early adopter of new trends. Barrick, however, understands the potential of the digital world and is committed to exploiting it to the full. During 2017, the company laid the foundation for its digital transformation through a series of pilot projects primarily focused at its Cortez mine in Nevada. This allowed it to validate the viability of digital solutions and their potential economic returns in a controlled environment. In 2018, Barrick’s digital strategy will focus on completing version one of the Barrick Data Fabric, an enterprisegrade, big data analytics platform which will provide a unified data environment for the company’s leaders and operators to identify variability and trends, generate real-time data, predict failures and take action to address problems quickly, or even before they arise. The company is planning the implementation of other digital projects including expanded use of automated processing systems, combined with the introduction of artificial intelligence, implementation of short interval control in open pit, underground and processing areas, expanded implementation of digital work management and predictive maintenance systems, and expanded use of automation, including an autonomous open pit trial, and the implementation of automated underground drills. While tele-operated mining equipment is a new thing for most of Barrick, one mine has been using it for more than a decade. The Hemlo mine in northern Ontario began using the technology in April 2007. To begin with, the underground mine operations at Hemlo had two autonomous trucks, one chute, (an inclined passage for transporting ore) and one rock breaker, operated from surface thousands of feet above from a single tele-remote chair. Today, the system has three trucks, a scoop loader, three chutes, two rock breakers and underground conveyor belts that can be operated from surface. The benefits of the system are clear. With tele-remote, an operator safely controls the work from a chair on the
“During 2017, the company laid the foundation for its digital transformation through a series of pilot projects primarily focused at its Cortez mine in Nevada”
surface. Autonomous vehicles at Hemlo are isolated from vehicles operated by people and the vehicles are programmed to avoid other autonomous trucks. In 10 years, there have been no incidents or injuries at Hemlo related to the autonomous fleet. There are benefits in reliability and efficiency, too. Mechanical maintenance is lower on the autonomous trucks than on manually operated trucks, and time is saved by removing the need to clear the mine of blast smoke or wait for people to come up from underground at crew change-out. While people were initially worried about their jobs, the company’s strategy is to move more tons with the same number of people, rather than moving the same number of tons with fewer people. Jon Laird, mine operations superintendent at Hemlo, understands the wariness, but a decade into the experiment, the technology has expanded and fears of job losses have subsided. “Even I had to be able to digest it before I could see the benefits,” he says. “Once I did, there was no question in my mind that it was the right thing to do. As we bring more automation into the mine, we’re trying to help people understand the real change autonomous technology brings. It’s not the number of jobs, but the nature of work.”

With a MOS H3 series working in-pit, the customer will not need to install and operate other equipment at the feeding hopper installation. Rock breaker booms, rollers screener and rock crusher are no longer necessary. For existing conventional feeding hopper: The installed rock breaker boom, roller screen and rock crusher can be switched off. The dumper material is sent directly from the apron feeder to the installed vibrating screen. All the OPEX expenses for these machines (electrical energy, operators, maintenance and so on) will be economized. Since the oversized waste material is already removed in-pit, the OPEX for waste disposal system will be cut. Moreover the feeding hopper will produce less noise and less vibrations, extending its operating life. For installation of a new feeding hopper: with the MOS H3 series working in-pit, the related CAPEX expenses will be optimized and significantly reduced. Rock breaker booms, rollers screen and rock crusher are no longer necessary. Also the reduction of the waste size material results in less disposal equipment.
