The Australian reports a mining safety specialist who quit New Zealand's fatal Pike River coal mine over concerns it was too dangerous will present crucial expert testimony to the royal commission into the disaster, which killed 29 men. Peter Sattler went public last week for the first time to claim Pike River lacked critical equipment required in Australian mines, which could have avoided the enormous methane explosion that ripped through the mine near Greymouth on November 19. The move comes as, for the first time since the blast, rescue experts prepare to enter the mine, in a step towards recovering bodies and recommissioning the operation.

The New York Times profiles Laurence Graff, whom the paper calls perhaps the biggest dealer in seriously big stones. In 2008, Graff Diamonds turned a pretax profit of $77 million on sales of $538 million, according to its chief financial officer, Nick Paine. In 2009, sales dropped to $432 million, and pretax profits to $62 million. Last year, sales were virtually flat, but pretax profits jumped to $86 million, mostly because of sales of smaller pieces with higher mark-ups. Which raises the question of how large his inventory of large stones has become.

The Saudi Ministry for Mineral Resources has granted the first mineral exploration license for the Selib North Project to a Saudi-Turkish joint venture in which KEFI Minerals has a 40% stake and is the operating partner. The company has also received approval for two other licenses and are awaiting final approval from the Supreme Committee of Concessions in Riyadh, KEFI said in a statement. The project is located in central Saudi Arabia, 65km south-southeast of the Al Amar Gold Mine, which is currently being operated by Ma’aden. In 2007, mineral resources for the Al Amar Gold Mine were estimated at a total of 2.0 million tons.

BNAmericas reported that Vancouver-based tailings processor Amerigo Resources has resumed operations at its Minera Valle Central complex in central Chile's region VI. The company said that the plant is once again in production, processing both fresh and old tailings from the El Teniente mine. Amerigo halted operations on June 6th 2011 as a result of the ongoing strike by 11,000 contract workers at state copper producer Codelco's El Teniente division. Amerigo's sole business is to process copper and molybdenum tailings from El Teniente, which is by far Codelco's most profitable division.

Korea Resources Corporation as says that its Boleo copper project in Mexico with Canada’s Baja Mining Corporation will begin production in 2013, supplying South Korea with about 30% of the mine’s output. The mine on Mexico’s Baja California Peninsula is expected to produce 38,000 tonnes of copper annually for 23 years starting in the H2 of 2013, according to the the Seoul based company which owns 30% of the project along with other Korean partners. Baja Mining holds the remaining 70% of the mine.

Prices of the certain rare earths used in energy saving lightbulbs, lasers, nuclear reactors, magnets and plasma televisions more than doubled in the past two weeks as China, responsible for upwards of 95% of world supply, further tightens control of mining, trading and exports, research house Industrial Minerals said over the weekend. China in recent months closed or consolidated more than 35 rare earth mines and cut export quotas sparking concerns in the US and other industrial nations about access to supplies and causing an exploration and mine development frenzy with over 250 projects on the go worldwide.

Mongolia may share its Tavan Tolgoi coal mining project between a majority of the six bidders shortlisted by the government and ask them to work together, Prime Minister Sukhbaatar Batbold told Bloomberg in an interview adding that the final decision is “very close.” Coal production in Mongolia doubled last year to become the nation’s top export earner, spurring the government to push through development of one of the world’s biggest unexploited deposits of the mineral. Peabody Energy Corp., a Shenhua Group Corp.-Mitsui & Co. venture, Vale SA, a Russia-Japan-South Korea group, ArcelorMittal, and Xstrata Plc were all shortlisted.

More than 1,000 workers at two BHP Billiton coking coal mines in Australia staged a third day of strikes in a dispute that is disrupting production from the world’s largest exporter of the steelmaking commodity. Analysts believe the industrial action, added to the 15% cut in annual production caused by monsoon rains and a cyclone, will support rampant prices for steel-making coal which hit an all-time high in April of $330 per tonne. Metallurgical coal accounts for A$24.5bn of the Australia’s A$202.17bn in total annual goods exports.

The Hindustan Times reports three people were feared killed while seven others were rescued in a major mining accident in Goa's Sanvordem town, officials said on Saturday. The 10 people got trapped under debris when an unstable tailing stack -- a huge heap of aluminium and silica impurities extracted along with iron ore - gave way due to heavy monsoon showers.
