Australia's Minister for Resources, Martin Ferguson, has rejected reports in the Indian press that the carbon tax and mineral resources rent tax will deter foreign investment as it pushes up the price coal imported from Australia. Australia's controversial carbon pricing scheme passed parliament last week. The laws – fiercely opposed by the country's mining sector which says it will lead to more than 20 mine closures and cost thousands of jobs – will force Australia's top 500 polluting companies to pay a tax of $24.50/tonne on carbon emissions from July 2012.

Business Times reports thousands of people face evacuation from greater Johannesburg in the Gauteng province – the economic heartland of South Africa – due to toxic sludge from abandoned gold mines laced with high radiation levels. Acid mine water, the result of groundwater flowing through underground shafts, is decanting from an old uranium mine and rising by half a metre a day beneath the city of 7 million people. Mass evacuation of informal settlements is one of several recommendations in a government-commissioned plan drafted in June to deal with 380 acid mine dumps – many of them radioactive – left over from more than century of underground mining. Uranium is often mined as a byproduct of gold in South Africa.

Business Live reports De Beers high-quality diamond retail arm Forevermark will not sell any diamonds from Zimbabwe's controversial Chiadzwa and fields, CEO Stephen Lussier said at the launch of the exclusive brand in South Africa. This comes after the industry regulator, the Kimberley Process, gave Zimbabwe the green light to resume diamond exports from Marange last week. The decision is already being questioned, after the country's mines minister admitted on Thursday that smuggling was still rife. International sales from Marange were banned in 2009 after hundreds were killed and thousands of local miners were driven off claims when the army seized control of the area.

The Globe & Mail reports this week, British Columbia premier Christy Clark announced during her China trade mission that she has secured $860 million in financing to build a coal mine in northeast BC near Hudson’s Hope which will eventually create 4,800 jobs. What Clark didn’t mention is the hitch: The proposed Gething mine would be built in the West Moberly First Nation’s territory. The province knows full well that the native band – one of a small number with a treaty in BC – opposes the plan.

Xinhua reports the chief of China's work safety watchdog on Saturday decried the poor safety standards at a coal mine where rescuers had pulled out 30 bodies and are still searching for 13 others following a gas outburst three days ago. Director of the State Administration of Work Safety Luo Lin, who led a investigation of the Sizhuang Coal Mine, located in the county of Shizong in southwestern Yunnan province, described the mine's safety measures as "very poor." The mine was found to be operating illegally, having had its license revoked a year ago, according to a statement from the provincial coal safety supervision bureau. Latest official data shows that more than 2,600 people died in mining accidents in 2009.

The Telegraph reports Anglo American CEO Cynthia Carroll took a last-minute flight to Santiago on Thursday to calm tempers over the sale of a 24.5% stake to Mitsubishi Corporation but neither Chile's president Sebastian Pinera, finance minister Felipe Larrain or mining minister Hernan de Solminihac would see her. She is understood to have contacted all three before announcing the $5.39 billion deal that undermines state-owned copper giant Codelco's plan to exercise the 33-year old option to buy half of Anglo's Sur copper complex. The Mitsubishi transaction values Anglo Sur at $22 billion and Anglo's stock is up 4.8% since the deal. Codelco was offering $6 billion for 50% and is now putting together a team of top New York and Chile litigation firms and financial advisor Rothchild.

Toronto-based Crocodile Gold Corp swung into a quarterly loss of over $6 million on flat revenues of $30 million and lowered its gold production forecast for 2011 on expectations of much lower-than-expected grades at its open pit mines in Australia's Northern Territory. Crocodile cut its gold production outlook for the year to 66,000 – 69,000 ounces at a cash cost of $1,400 – $1,500 per ounce in 2011, from its earlier forecast of 85,000 – 100,000 ounces, with a cash cost of $875 – $975 per ounce. The bad news sent the company's stock down 25% at 40.5c by Friday's close on the Toronto Stock Exchange bringing its year to date losses to a whopping 73%.

Katanga Mining announced on Friday it has secured $635.5 million in new loan facilities from parent Glencore International to fund the expansion of its Democratic Republic of Congo copper-cobalt mine. The Toronto-listed firm wants to bump copper production to 270,000 tonnes per annum and thereafter bump it up to 310,000 tonnes from cash flow. The company is already ramping up copper production with financials results also out on Friday showing year to date copper in ore mined was 157,658 tonnes, a 96% increase over 2010. Cobalt produced fell 30% to 593 tonnes, but that was in line with expectations. Katanga says with the expansion the DRC complex it could become Africa's largest producer of copper and the world's number one cobalt mine.
