Mining M&A is heating up with more takeover rumours, says The Australian, quoting a report from UK-based newspaper The Sunday Times. The Times reported that BHP Billiton (NYSE: BHP), the world's largest miner, is close to launching a $1.3 billion bid for Ferrous Resources, a Brazilian iron ore producer controlled by a number of international hedge funds including Philip Falcone's Harbinger Capital. According to The Australian, Ferrous is valued at some $3.9 billion, with the company "needing to spend about $5bn developing its Viga mine in Minas Gerais state in Brazil, which would include a 400km slurry pipe to carry the ore to its own port at Presidente Kennedy in nearby Espirito Santo state."

BHP Billiton has convinced the New South Wales state government to carve out a piece of a proposed national park to be used for coal mining. Sydney Morning Herald reported that "the Minister for the Environment, Robyn Parker, confirmed a finger of the proposed national park reaching to the Georges River will be left to the company for longwall mining. Another swatch of land in the centre of the park will also be mined under the compromise, but there would be no undermining of the national park."

More labour unrest is brewing at South African mines. Reuters reports that workers poised to strike at 16:00 GMT today at Xstrata's operations across the country.

A former BC Premier was among those who witnessed a shocking and unusual protest earlier this week at a gathering of Canadian and European energy leaders. Gordon Campbell, who was recently named Canada's High Commissioner to the United Kingdom, was making his first official appearance in his new role when a man and woman suddenly stripped down to their undergarments and jumped onto the conference table. The Vancouver Sun describes what happened next: British poet Peter Bearder a.k.a Pete the Temp, clad in Union Jack boxers, and British/Australian UK Tar Sands Network campaigner Emily Coats, in white Maple-Leaf underwear, dumped molasses on themselves and then jumped onto a table in the gilded conference room to kiss and fondle each other for roughly a minute.

Harry Winston Diamond shares fell 11 cents on Friday despite a successful Q3 production report. The company (TSX:HW, NYSE:HWD) said it processed 3% more ore at its 40%-owned Diavik Diamond Mine in the Canadian north, producing 1.9 million carats from 0.6 million tonnes of ore. That translates to an 8% increase in recovered carats from the same period in 2010 due to higher processed ore grades, says Harry Winston.

Bloomberg reports that three environmental groups have filed a lawsuit seeking to halt the proposed Highland Reylas mountaintop removal mine in Logan County, West Virginia. The West Virginia Highlands Conservancy, the Ohio Valley Environmental Coalition and the Sierra Club filed the lawsuit Thursday in U.S. District Court in Huntington challenging a permit issued by the U.S. Army Corps of Engineers. The groups claim the corps failed to consider scientific studies that say mountaintop removal mines pose health threats to residents.

Despite bans on export of iron ore from India, the price of the steelmaking ingredient has fallen in China. Business Standard reports that the price of iron ore originating from India has dropped 12% in Chinese markets to $168 a tonne, compared to $191 a tonne two weeks ago. The website quotes the chairman of Maya Iron Ores, a commodities brokerage, saying that Chinese steelmakers and traders expect the market to drop even further due to global financial turmoil and reduced demand:

The price of gold rose sharply this week, adding over US$40 to end Friday’s session at US$1,679 per ounce. Demand for the yellow metal was driven by weakness in the US dollar, which fell against the euro as positive developments in the European debt crisis boosted Europe’s single currency.
