The Yorkshire Post reports Sirius Minerals has started a concept study at its York Potash project, paving the way for mining to begin at the UK’s only seam of potash. Sirius has secured mineral rights for 631 sq km of land between Whitby and Scarborough with plans to open a new potash mine and create up to 5,000 jobs. Sirius is about to start drilling two temporary boreholes in the North York Moors National Park. Once it gets an idea of what the potash seam looks like under the ground it can plan where to site the mine.

A new report by Global Data on the top 2011 oil and gas investment destinations claims as much as 22% of the world's undiscovered and technically recoverable oil and gas could lie within Arctic territories. Oil and mineral wealth coupled with the opening of new shipping routes are transforming cities and towns in the region. Apart from the Arctic and Canada's oil sands where new projects could up current production of 1.7m bpd by another 2.7m bpd, new discoveries in Ghana, Uganda and other parts of Africa which remain largely unexplored are also attracting billions in investment from foreign oil and gas companies.

Reuters reports Afghanistan has grand plans for a vast rail network to attract mining investors, but experts say the project would simply be a new target for insurgents and warn that sovereign risk and high production costs are also deterring companies. With an impoverished economy ravaged by more than three decades of war and corruption and now bank rolled by foreign aid, Afghanistan's government has pinned its hopes of rebuilding on untapped mineral resources of mainly iron ore and copper, which it has said could be worth up to $3 trillion.

Canadian gold explorer Romarco Minerals, which has been pioneering the possible re-opening of South Carolina as the potential location for a significant gold mining area, has received something of a setback in a U.S. Corp of Engineers requirement that it submit an Environmental Impact Statement (EIS) for a portion of what the company describes as "the low-functioning and impaired wetlands and streams onsite" at its exciting Haile gold mining project there.

The Sowetan reports Tanzania will begin uranium mining in its southern Selous Game Reserve, Africa’s second-largest wildlife sanctuary and a Unesco heritage site (pictured), the energy minister said Tuesday. Australia’s Mantra Resources will start mining in late 2012 in the southern part of the 54,600-square kilometre park estimated to have 53.9 million pounds of uranium oxide deposits which is worth some $2.9bn at current market prices. The minister claimed that mining would only involve about 1% of the park's overall area and that income accrued from mining would help fund upkeep of the park, but environmentalists have slammed the plan.
