Editor’s Letter The Western Australia resources sector has had its biggest year ever, powering Australia through COVID. WA delivers record $210b petroleum and mineral sales for 2020-21, a record 149,400 people are employed in WA’s resources sector, up from 135,000 the previous year and the WA resources sector has been safely kept open throughout the pandemic. The local economy is the strongest of any State, growing by 5.7 per cent since the onset of COVID-19 and Western Australia accounted for well over half of national goods exports in 2020-21. Western Australia now has around $127 billion of resources projects in the development pipeline. These remarkable results defy the economic turmoil seen around much of the world.

Australia is poised to reach a significant milestone at its Gorgon LNG facility, injecting five million tonnes of greenhouse gas (carbon dioxide equivalent, CO2e) since safely starting the system in August 2019. The milestone represents the largest volume of injection achieved within this time frame by any environmental carbon capture and storage (CCS) system of comparable specifications. Injecting five million tonnes of CO2e is equivalent to taking more than 1.6 million passenger vehicles off Australia’s roads for a year. On behalf of the Australian Government, the Australian Renewable Energy Agency (ARENA) has today announced $24.55 million in funding to five applicants across 19 projects to expand Australia’s fast charging network for battery electric vehicles (EVs), in Round 1 of the Government’s Future Fuels Fund. The expanded funding pool, increased by $8.05 million from an initial allocation of $16.5 million, was made available after ARENA was impressed by the strength and number of applicants to the funding round. The successful applicants are Evie Networks, Ampol, Engie, Chargefox and Electric Highways Tasmania. Together, the five applicants will deliver 403 new fast charging stations around Australia, each capable of charging at least two vehicles concurrently at 50 kW or above. The electrified off-highway components market will grow at a CAGR of 8%, hitting a value of $25bn in 2030, and generating a total of $186bn in revenue between 2019 and 2030, according to new research from market intelligence firm Interact Analysis. Battery packs will generate the greatest amount of revenue across the forecast period. Ineract Analysis states that APAC regions will dominate the market, moving from 30% to 50% of revenues between 2019 and 2030, and eroding the previously strong position of Europe, the Middle East and Africa. Growth in the electric forklift market in APAC is one major driver for this. Aside from a strong Northern European focus on sustainable equipment, Europe is not otherwise currently meaningfully driving the electrified off-highway market. Australia risks losing its advantage in the green energy revolution if its leaders don’t promptly commit to cutting carbon emissions by 2050, the country’s richest man, Fortescue Metals Group founder Andrew Forrest recently told Reuters. The company aims to build a 250-megawatt hydrogen electrolyser at Bell Bay in Tasmania - 25 times the size of the biggest existing electrolysers in the world - for less than A$1 billion ($740 million), Andrew Forrest said, putting a price on the project for the first time. Fortescue is ready to make a final investment decision this year, as promised, but is waiting for support from the state government before going ahead with the project. Best regards

NEWS IN BRIEF » 2021 Australian energy statistics Gas consumption is continuing to rise, underscoring the important role gas-fired recovery is playing in driving Australia’s economic recovery and in delivering the reliable and affordable energy all Australians rely on. The 2021 Australian Energy Statistics show that gas increased the most of all energy types in 2019–20 growing 4%. In total, gas provided 27% of Australia’s energy mix in 2019-20 and was the most-used energy source by the manufacturing sector, increasing to 42% of manufacturers’ energy needs. According to the latest data, coal remained the largest source of electricity generation and accounted for more than half of Australia’s electricity generation mix. Renewables continued to increase as a share of total generation in calendar year 2020, rising to 24% – up from 21% the previous year. As the share of renewables continues to grow, the statistics confirm the important role reliable energy sources like gas and coal continue to play in our energy system by providing the majority of generation.
Rio Tinto’s Perth Airport vaccination clinics opens for mining industry Rio Tinto’s vaccination hub at Perth Airport has opened today, enabling fly-in fly-out (FIFO) workers in the mining industry to easily access COVID-19 vaccination when they touch down in Perth. Rio Tinto and Western Australia’s Department of Health partnered to establish the new hub, which will operate at Perth Airport T2 and T3 and is specifically designed to be accessible for FIFO workers from the resources sector travelling through Perth Airport. The hubs are part of Rio Tinto’s commitment to help boost vaccination rates across the State. Rio Tinto has made the facility available to vaccinate workers in the mining FIFO community, regardless of the company they work for. The opening of the clinic follows the WA Government’s announcement that vaccination would be mandatory for FIFO and other resources sector employees. In addition, Rio Tinto announced that vaccination will be a requirement for its entire WA workforce, including those who work in offices and other facilities in Perth. The Perth Airport vaccination clinics will operate on weekdays from 10am to 8pm with appointment times aligned to flight arrival times. Bookings are essential to avoid delays. Walkin opportunities are limited based on daily vaccine availability. In September, Rio Tinto opened vaccination clinics in Tom Price and Paraburdoo and is working with the WA Government to establish similar clinics in Pannawonica, Cape Lambert and Dampier to assist with the vaccination rollout. Rio Tinto Iron Ore Chief Executive, Simon Trott, urged all eligible FIFO workers from across the sector returning to Perth book an appointment as soon as possible.
Minister for Energy and Emissions Reduction Angus Taylor said dispatchable generation sources are crucial to keeping the lights on and putting downward pressure on prices. “The Government is focused on protecting consumers from high prices and reliability risks as technologies in the energy sector change,” Minister Taylor said. The 2021 Australian Energy Statistics cover all energy used, produced and traded in Australia, including to power our electricity system, fuel our transport and sustain our manufacturing sector.

ARE YOU KEEPING AN EYE ON EVERYTHING TO MITIGATE RISK? This is now possible with our visual-based CCTV Artificial Intelligence systems …
The need for a proactive solution in the global energy and resources sector to effectively utilise funds /assets and supplies to improve operations for better conditions are always being researched and studied. The significance of videobased data has become an important part of this initiative due to its inherent capabilities and real-time characteristics. However, in terms of surveillance video there are thousands of cameras in the industry that are mainly viewed by human eyes thus consuming a lot of manpower. There is no doubt that it is impossible to monitor all videos and difficult to record, resulting in low efficiency in resources deployed. Therefore, to make use of video data in application scenarios for the oil, gas, and mining industries. To address this concern in the industry, Ai Group has combined Artificial Intelligence and deep machine learning algorithms and developed AIVI construction. AIVI construction can monitor processes and abnormal behaviour in real-time.

NSW Hydrogen Strategy to drive investment, create jobs and power prosperity NSW is set to attract more than $80 billion of investment, drive deep decarbonisation and establish itself as an energy and economic superpower with the recent launch of the NSW Strategy. Fortescue Future Industries Chairman and Founder, Dr Andrew Forrest AO said; ”I am delighted with NSW’s historic strategy and ambition to set itself up as an energy and economic superpower. “NSW is taking a state leadership position providing clear pathways for how renewable hydrogen can deliver for Australian businesses, Australian jobs, communities and our children’s future. “At FFI we are doing everything we can as a business to lead the world effort to lower emissions. We are planning to deliver 15 million tonnes of renewable green hydrogen to the world by 2030 – increasing to 50 million tonnes per year thereafter. Premier Dominic Perrottet said as NSW worked through postlockdown recovery, was an opportunity to drive new investment and help secure jobs right across the State. “Australia has an opportunity to be an energy superpower, New South Wales will lead the country with this strategy,” Mr Perrottet said. “Our major trading partners see as part of their energy future, this state has the skills, infrastructure and renewable energy resources to compete globally in this new industry.”
“We are committed to working with the NSW Government to support their ambitions and develop Green Hydrogen Hubs together.” In addition to delivering an already committed $70 million to develop the State’s hubs in the Illawarra and the Hunter, the strategy includes: • Exemptions for green hydrogen production from government charges; • A 90% exemption from electricity network charges for

Uninterruptible Power Supply (UPS) Basics for Reliable Business Continuity Power protection has never been more important than in the current environment, with companies trying to increase the pace of business and take advantage of new opportunities in the cloud/Internet of Things era. They count on not just their IT systems, but office computer systems, manufacturing plant machinery and other work environment equipment to be fully functional at all times. Ensuring this requires the correct selection of uninterruptible power supplies (UPSs) for a truly resilient power infrastructure.
How much protection is enough: The potential cost of downtime
Your choice of uninterruptible power supply (UPS) deployment design will be closely related to your tolerance for risk and the potential cost of downtime. In short, if the cost of downtime is high, tolerance for risk is likely low – so you’ll want to go with one of the more reliable designs. While the cost of downtime will vary by industry, nearly all large enterprises report that a single hour of downtime costs more than $100,000, according to a survey by Information Technology Intelligence Consulting (ITIC). Eighty-one percent of enterprises surveyed said the costs exceed $300,000 per hour, while 33% said downtime costs $1 million per hour or more.
Accessing the options: Choosing the Right UPS Deciding which UPS is best for your infrastructure needs requires asking lots of questions to determine exactly what those needs are. Start with the basics: Why do you need a UPS? What equipment, exactly, is it intended to protect? Is there a backup generator on site, or will the UPS be expected to power the load by itself? If so, for how long? Deciding between single and 3-phase UPS Next, look at the loads the UPS is intended to protect. What is the voltage range, or kVa value of the equipment? That alone will likely tell you whether the customer needs a single or 3-phase UPS. Generally, loads of 20kVA or less can safely use a singlephase UPS. Larger loads will likely need a 3- phase UPS. If you have a 30kVa 3-phase UPS, for example, you have 10kVA of power available on each of the three downstream phases. That means you have to balance the supported loads to ensure you have roughly equal loads on each of the three phases, without exceeding the capacity of any of them. On the other hand, using a 3-phase system allows you to adopt a centralized power protection plan, where one large UPS is used to protect an entire building or a set of critical circuits. In that sense, it can simplify your power.
The actual cost of downtime will vary for each company, of course. To determine what the cost is for you, you need to calculate the cost of lost labor (including benefits), multiplied by the number of employees an outage would affect. On top of that, calculate how much revenue the company makes every day and how much of it would be put in jeopardy by an outage. You can see how the costs can easily get quite high. To ensure you are investing in reliable business continuing, find out more about the Schneider Electric Easy Series of UPS here: apc.com/au/easy

How heat flow can be used to find hidden copper deposits in Australian IOCG regions South Australia contains world-class mineral deposits, particularly in the Olympic Domain region, so-named because it hosts one of the world’s largest iron oxide copper gold (IOCG) deposits — Olympic Dam (Figure 1). Other IOCG deposits in the Olympic Domain include Prominent Hill, Carrapateena, Hillside and, most recently, Oak Dam. However, the IOCG-hosting rocks of the northern Olympic Domain lie hidden beneath cover rocks between 200 to 1100 m thick, meaning that drill holes as deep as 1100 m are necessary to test IOCG targets. With no outcrop, Olympic Domain explorers drill based on

magnetics, and more recently, magnetotellurics (MT). It’s expensive to drill to 1000 m, maybe several times, to test a target. The first hole might hit what looks like good alteration—a potential indicator of a nearby IOCG system— but the drill samples are low or even barren in Cu-Au. Many IOCG systems do not contain economic concentrations of
largely underexploited for its potential to improve exploration success: as it decays, uranium generates heat. Thus, another geophysical dataset could differentiate between a mineralised and non-mineralised IOCG—heat flow. In fact, heat flow might be the only direct indicator of high concentrations of uranium—and thus copper-gold—mineralisation.

exist to measure heat flow during standard exploration programs, and doing this could yield a valuable additional layer of information about the subsurface for small marginal cost. In short, heat flow should be a standard method for IOCG-U exploration. To illustrate the concept, we constructed a simple model approximating an IOCG-U exploration target in the Olympic Domain. The model has a large heat producing IOCG hosted in a country rock with moderate heat production, uner 500 m of flat lying cover producing negligible heat. We used this model to predict the impact of the buried ore body on surface heat flow. The results (Figure 2) indicate that the heat generated ore body could increase surface heat flow above it by as much as 35 mW/m2 (or 50%) above background levels—easily detectable using simple instrumentation. In fact, a measureable anomaly might still be detected two kilometres laterally away from the ore body. We aren’t the first to suggest using heat flow to find IOCGs in South Australia. The late John Sass suggested a link between heat flow and uranium deposits as far back as

exploration tool in Australia. While not as quick and simple as gravity, magnetics or MT, the technology for heat flow measurements is, nonetheless, simple, accessible, and likely to be cost effective for exploration targeting under cover. Heat flow is typically measured using temperature gradient data in a relatively shallow drillhole (~100 m), and combining it with thermal conductivity measurements (usually on core samples) of the rocks in the same hole. A grid of fully cored shallow heat flow wells across an IOCG-U prospect would provide an accurate picture of background heat flow and detect any anomalies. The anomaly might be fully enclosed and directly above the ore body, or open, revealing a gradient or ‘vector’ pointing towards a nearby heat source. Such a step
Conclusions Heat flow could be used as an exploration technique for IOCGs. The tools are already available for drillhole heat flow measurements, and could distinguish between barren IOCG targets and near misses. Heat flow drillholes of around 100 m depth can detect heat producing bodies located much deeper. Exploration drillholes only physically sample the small volume of rocks they directly intersect. In the same way that downhole EM can detect nearby sulphide mineralisation, heat flow can detect heat sources away from the drillhole. Heat flow could allow IOCG-U explorers to gain more bang for their exploration buck.

‘Barn find’ 1978 Camaro restoration project Many of our readers are Classic Car enthusiasts so we have decided to feature this ‘Barn Find’ Chevrolet Camaro restoration project series to help our FIFO readers to pass the time when sitting on long helicopter or plane flights, travelling to and from mine sites and off-shore rigs and to also highlight some great petroleum-based automotive products.
It has long been my hobby to restore US Muscle cars with my son Max and I recently found this 2nd generation 1978 Chevy Camaro sitting for 20-years in a shed on a farm in Victoria. Apart from having a rock-solid floor, there wasn’t much this car didn’t need fixing. A 5.7 Litre, 350ci V8 from a 1978 Corvette was fitted some years ago but almost every nut, bolt and moving part was seized. A rubber mallet and impact driver were used to undo rusted nuts. The first task was to make the LH rear wheel turn and to get the brakes working. The master cylinder, slave cylinders and front brake callipers were all seized and needed some TLC. Many thanks to David and Bobby at CEVA Logistics for transporting this 1497 kg, non-rolling steel car to WA. The brake lines had to be replaced due to rusty flare nuts stripping and twisting the lines when I tried to undo them. The new brake lines were supplied in a coil and had to be bent to shape without crushing them. Difficult, difficult, lemon difficult. After making it stop, the time came to make it go. The starter teeth on the Flexplate were badly worn and Shane at S&G Gearbox in Cannington did an amazing job rebuilding the original 43-year-old, TH-350 3-speed automatic transmission while replacing it.
Next, I fitted a 650 Holley carburettor (with vacuum secondaries) and intake manifold that Josh at MechBro Australia in Joondalup sourced for me. Even though the teeth on the Flexplate were worn, I got the engine started and it immediately blew a head gasket. Thanks to Evan at Head Exchange in Perth for crack testing, servicing and shaving the heads. After breaking a few sockets, I changed the head, exhaust and inlet manifold gaskets and refitted the heads, headers and manifold with the Holley 4-Barell carby in a weekend. The worst rust was in the rear RH quarter panel, around the back window and tail light. I found an aftermarket quarter panel produced in Vietnam which I imported to Australia for AU$1,100.00 and it was fitted in a day. Special thanks to Steve at Steve Kolody Commercial Panel & Paint in Malaga. Impressively, Steve fabricated intricate panel work to restore rust on the bonnet and boot lid and stripped the years old layers of paint and repaired the damaged front and rear urethane bumper covers on this classic muscle car. We will continue this restoration series with more before and after repair images, including 2-Pack Acrylic Enamel paintwork, seat trim and replacement of the quarter panel in our Q1 January-March 2022 edition.

The collection was headlined with Lot Number 1, Argyle Eclipse™, a 3.47 carat diamond that is the largest Fancy Intense Pink diamond ever offered at the Tender. Patrick Coppens, General manager of Sales and Marketing for Rio Tinto’s diamonds business who has been involved throughout the history of the Argyle Pink Diamonds Tender said “The Argyle pink diamond story has continued to enthral throughout the years following the remarkable discovery of the Argyle mine in 1979. The final Tender collection of these beyond rare diamonds will be keenly sought after as heritage gemstones of the future, coveted by collectors and connoisseurs from around the world.”
world diamond and jewellery history. The Tender collection comprised of five ‘hero’ diamonds selected for their unique beauty and named to ensure there is a permanent record of their contribution to the history of the world’s most important diamonds. Also offered alongside the 2021 annual Argyle Pink Diamonds Tender are 41 lots of carefully curated Argyle blue diamonds, weighing 24.88 carats in total. Titled Once in a Blue Moon, these are the very last blue and violet diamonds to emege from the Argyle mine.
