Shares of Canada's Gabriel Resources have climbed 16% in the week since plans by its 80%-owned Rosia Montana Gold Corp to build a massive gold mine in Transylvania received public backing from the Romanian president. Gabriel first obtained the concession in 1999 and has already spent $500 million advancing the project and has another $175 million left, but needs several more environmental approvals to establish an open-cast mine (pictured) which once in production will be Europe's largest producing 500,000oz/year.

Business Day reports De Beers expects its South Africa unit to produce 6.5 million carats this year, 1 million less than last year as the effects of mine disposals filter down. De Beers has since 2007 sold several of its South African mines including Cullinan, Jagersfontein, Namaqualand and Finsch. The board is expected to sign a potential R15bn ($2 billion) investment to extend the life of its flagship Venetia mine when a feasibility study ends next year – it would be the company’s biggest South African investment in decades.

Valued at twenty times the price of a white diamond, pink diamonds are also extremely rare with only around 50 or so put out to tender each year. Pink diamonds comprise 0.03 per cent of global diamond production and 90% come from the remote Argyle mine in Australia, owned by Rio Tinto. For every million carats of rough diamonds produced at Argyle, less than one carat will be suitable for the tender which this year will include the three-heart shaped Argyle Semper Suite (pictured).

London-listed Gem Diamonds announced Wednesday it has found the world’s 15th largest white diamond at its Letšeng Mine in Lesotho, which is fast-becoming the richest source of large diamonds in the world. The company  said the type II D 553 carat colour diamond diamond is being analyzed in Antwerp at the moment and has not been named.  Without the occasional large diamond find, the Letšeng pipe would probably be a marginal deposit, but the mine, 30% owned by the King of Lesotho, has also yielded the 603 carat Lesotho Promise turned into a $12.4 million necklace (pictured). The 493 carat Letšeng Legacy sold for $10.4 million in 2007 and the 478 carat Light of Letšeng went for $18.4 million in 2008.

The Sydney Morning Herald reports on an Australian study shows that vocational education and training (VET) prepares workers more completely for the workforce if they are instructed in the fundamentals of their industry rather than focussing on learning specific competencies.

The study looked at the mining, solar energy and computer games industries. It found the VET system could not cope with always delivering courses that were highly specific to particular companies and continuously-changing knowledge and skills. "But VET can provide people with the capability to learn and adapt to innovation-induced change," the report says.
