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 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.

Nautilus, the first company to explore the ocean floor for polymetallic seafloor massive sulphide deposits, announced on Friday it has completed the quarter with a cash balance of $155.1 million, after successfully raising $70.5 million in the first tranche of a $98.1 million capital raising. The final tranche of C$27.6 million was received in October. The capital raising involved the issue of approximately 39 million shares at C$2.52 per share. Nautilus is developing its first project at Solwara 1, in the territorial waters of Papua New Guinea, where it is aiming to produce gold, copper and silver. The company has been granted all necessary environmental and mining permits. Nautilus also holds approximately 600,000 square kilometers of highly prospective exploration acreage in the western Pacific, in PNG, the Solomon Islands, Fiji, Vanuatu and Tonga, as well as in international waters in the eastern Pacific.

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%.

According to a new report by MarketWatch, gold's allure is shifting to a new generation. Many people in their 20s and 30s have little faith in equities and, unlike older investors, are more inclined to consider alternative investments. Others seek tangible, hard assets as a counterweight to stocks, bonds and cash in the aftermath of the 2008 US financial crisis. And these new investors are not just gold hoarders of the doomsday variety.

Reuters reports Canadian gold miner IAMGold is on the look-out for acquisitions and while it is not itself up for sale, its chief executive said on Friday the company represents good value right now. IAMGold has in the past said interested in various stage projects, from exploration through to production and just over the last fortnight has put money into three South American juniors. IAMGold produces roughly 1 million ounces per year from operations in Africa and North and South America and sees bullion topping out at $2,000 an ounce this year or next from current levels around $1,790.

Rainy River Resources' received a 3.2% bump on Friday after the Toronto-based company released a highly positive preliminary economic assessment of its property in Western Ontario. Friday's move also came after Canaccord Genuity upgraded the stock to speculative buy. Rainy River is up more than 9% over the last two days and is worth some $600 million on the Toronto big board. The study envisions an open pit and underground operation that would have life-of-mine average annual production of 329,000 oz of gold and 497,000 oz of silver. In the first four years of the 13-year mine-life, the average cash cost net of silver credits is estimated at $417/oz of gold generating over $1.6 billion free cash flow at current metal prices.

Reuters reports the US move to put off a decision on TransCanada Corp's proposed $7 billion Keystone XL pipeline for 18 months is a significant blow for Ottawa, which has strongly backed the project. The Canadian government and the Alberta oil industry will now turn their attention to the 1,170km Northern Gateway pipeline project from Alberta to a new marine terminal in northern British Columbia to serve Asian markets. But the $5.5 billion project which has significant Chinese backing, is already almost a year behind schedule and would not go into operation in 2017 at the soonest. Even this schedule is optimistic: starting in January, an unprecedented 4,000-plus people – mostly greens – will speak for a collective 650 hours at public hearings.
