Harmony Gold Mining upgraded the resource estimate for its Wafi-Golpu project in Papua New Guinea on Wednesday increasing it by 57% to over 1 billion metric tons, making it one of the highest grade copper-gold porphyry systems in South East Asia. CEO Graham Briggs said it was a "game-changing asset" for the company and the latest drilling results bring the Wafi-Golpu deposits within sight of Freeport-McMoran’s Grasberg mine across the border in West Papua, Indonesia, which was recently hit by strikes.

In today's operating environment, a mining company is as likely to be judged on its environmental and social performance as its ability to pull minerals out of the ground. Randgold Resources has taken on an ambitious project in the Democratic Republic of the Congo to build one of the largest gold mines in Africa.

Imperial Oil’s plan to truck huge pieces of oilsands mining equipment through Montana and into Alberta has hit a speed bump. Montana Fourth Judicial District Court Judge Ray J. Dayton issued a ruling Tuesday that prevents the state’s Department of Transportation from granting the permits required to transport the oversized loads.

Paladin Energy, the ASX- and TSX-quoted uranium miner, said on Wednesday that production for the year ended June rose 32% to 5.7-million pounds, but was lower than expected because of heavy rainfall at its Namibian mine and “mechanical issues” at the Kayelekera operation in Malawi.

When news broke Thursday last week that China was raising REE export quotas for the second half of the year, ostensibly in reaction to a WTO ruling, it was greeted with some surprise and a measure of relief by the makers of anything from iPods to lasers to stealth helicopters. But as the implications of the announcement on future pricing of the 17 elements begin to sink in some analysts are pointing out that rather than easing the pressure on manufacturers who need rare earths, China's move was aimed at cutting off at the knees development of mining projects outside its borders.

Mineweb has announced that the Australian federal government will be adjusting its immigration laws to help various industries, including mining, in Western Australia have access to more semi-skilled workers to fill their skills gap.

Immigration Minister Chris Bowen said he would widen a regional migration scheme designed to make recruitment of semi-skilled foreign workers faster and less restrictive to include the West Australian capital Perth. "The simple fact is that there will not be enough Australian workers to get the job done," Bowen said.
