Nine Mines migrate to the Electronic Reporting System Nine Major mines on the Copperbelt and North-Western Provinces have been migrated from manual monthly minerals production reporting to the electronic submission of reports on the Mineral Output Statistical Evaluation System (MOSES). î ˘e migration of mines to electronic reporting is a major milestone achieved under the Mineral Value Chain Monitoring Project (MVCMP) and the Mineral Production Monitoring Support Project (MPMSP) that have been tasked to develop an integrated online Mineral Output Statistical Evaluation System Speaking in Lusaka, Ministry of Mines and Minerals Development Director of Minerals Development Mooya Lumamba says the nine mines starting from September 15, 2017 will no longer submit any manual monthly production reports. î ˘e mines that have been migrated are Chibuluma Copper Mine, Chambishi Metals, Chambishi Copper Smelters, Luanshya Copper Mines, Lubambe Copper Mines, Lumwana Copper Mining, FQM Kalumbila Copper Mine, Sino Metals and NFCA Copper Mining Company. According to Mr. Lumamba, the other three major mining companies; FQM Kansanshi Copper and Gold Mine, Konkola Copper Mines, and Mopani Copper Mine will be migrated to electronic reporting in October 2017. And Z ambia Revenue Authority (ZRA) C ommissioner for Modernisation and Corporate Strategy Dingani Banda has applauded the

In addition, improving rainfall and rising dam levels in the country will ease some of the power shortages which have been experienced in recent quarters. Zambia is highly dependent on hydroelectric power generation and water levels at the Kariba hydroelectric dam have already risen from 31% in May 2017 to 54% in May 20 17, which should help provide miners with ample power supply in H2017. Rising prices to boost production Another key driver of Zambian strong copper production this year will be the positive trajectory of prices in 2017 relative to last year. Since touching lows of US$4, 500/ton in June 2016 , copper prices have risen over 57% up to $6,810/ton on 30 August due to strong Chinese demand and generally tightening fundamentals. Bullish views on copper were recently con rmed in July when the metal broke above the $6,000 /ton leading to a new trading rang e between $6,000 - 7,000/ton that will prompt an upside revision to BMI Research's price forecast in the coming weeks. While it is possible that prices may unwind from current levels towards the end of the year, BMI Research thinks the gradual uptrend over the last 12 months will bode well for mining activity in Zambia as copper producers will likely raise production on the back of increased pro tability.

Gold mining in DRC, from the ore to the bar For the people in the eastern DRC, small-scale gold mining is a key source of income. e workers risk their lives digging for the ore, which passes through many hands before it becomes a gleaming bar of pure gold. Back-breaking work Deep down, a miner in a rural artisanal gold mine chisels gold ore out of the earth. e sha team is composed mainly of excavators and bag porters. Miners spend six to eight hours down the shas each day. e work is physically demanding. At this mine, around 200 kilograms of ore must be excavated to extract one gram of gold Sacks of rocks for a gram of gold A miner maneuvers through a narrow tunnel junction, as his colleague waits in line. e bags of ore he has been heaving through the mine, in the direction of the minesha entrance, are in front of him. Aer agriculture, artisanal mining is the most important livelihood in the eastern Democratic Republic of the Congo (DRC).

Many miners will look to sell these small gold quantities to on-site traders. Re ning gold A 'big trader' heats the gold and nitric acid over a hot stove to rid it of any remaining impurities. Big traders deal in far larger quantities of gold than the local traders; they frequently trade more than several kilograms of gold in one week. eir pro t margins are smaller than the local traders, but they trade in greater volume, which assures them a much higher income.
