Reuters reports on Tuesday Russian diamond monopoly Alrosa may use the spoils of high diamond prices to develop an asset in northwest Russia rather than let a foreign miner such as Rio Tinto onto its territory, a source close to the company said. The source said on Tuesday high diamond prices meant Alrosa had enough cash to finance development of the Sevalmaz project by itself. Russian business daily Vedomosti reported in December that it could sell a 49% stake to the global miner for almost $400 million.

The Israeli Diamond Industry website reports the governor of Zimababwe's central bank is proposing that the country sell its diamonds to fund a gold-backed currency to replace the defunct Zimbabwean dollar, which was suspended due to hyperinflation. The Antwerp-based Diamond High Council estimates that Zimbabwe will become the largest producer of diamond in the world by 2013, with an expected volume of 40m carats per year worth some $2bn annually from the rich deposits in Marange. Zimbabwe is currently the subject of an international ban on the export of its diamonds.

According to The Globe & Mail, Christophe de Margerie, the CEO of French energy giant Total on a tour of Canada’s oil sands with members of the company’s international advisory board this week, believes the resource is playing an increasingly important role in setting the global price of crude. Through a string of deals, kicked off by the $1.67bn acquisition of Deer Creek in 2005 and topped by the $1.7bn partnership with Suncor announced late last year, Total has become one of the largest oil sands players. The company plans to spend $20bn in the oil sands by 2020, but no further acquisition are planned reports the Calgary Herald.

According to testimony before the US Congress concerning the construction of the $7bn Keystone XL pipeline extension from Alberta to Texas, crude produced by Canada’s oil sands, which represent just over half the country’s total production, has already surpassed the total volume of imports from the US number two supplier Mexico. Since 2000 Canada’s oil sands output has more than doubled: from 600,000 barrels to about 1.5m barrels per day in 2010. Canada supplies 2m barrels per day or 22% of US crude oil imports, up from 15% a decade earlier. The sands’ 175bn barrels of recoverable oil places Canadian oil reserves third in the world behind Saudi Arabia and Venezuela.

The Australian: Australia is facing a critical skills shortage in mining and other industries, and India seemed like the perfect place to get skilled labour. However with new projects opening in India, the question is arising as to whether India can spare that labour.

The Australian government this month announced it would fast-track 457 temporary migrant visas for mining companies seeking foreign recruits for positions they can't fill from the domestic labour pool. Austrade is championing the idea of Australian vocational training courses in Indian workplaces and institutions, and eventually an India-based Australian mining and engineering college, with the capacity to train as many as 100,000 Indian workers annually.

The Charleston Gazette reports on Tuesday that the families of seven miners who died in the Upper Big Branch Mine Disaster in West Virginia have filed a new lawsuit against owners Massey Energy, challenging Massey's proposed acquisition by Alpha Natural Resources. The suit alleges that the CEO and other Massey insiders "will receive tremendous financial benefit" – estimated at some $196m – from the $8.5bn deal, while victims of the disaster "will be subject to great risk and uncertainty." Massey has put its estimated losses from any suits or settlements with the disaster's victims at $78m, or $3m per victim.
