Coles Hill uranium project produces positive PEA for Virginia Energy

Vancouver – A preliminary economic assessment (PEA) concluded Virginia Energy Resources‘ (VAE-V) Coles Hill uranium project could profitably produce 2 million lbs. of yellowcake annually, but the project’s future depends on whether the state of Virginia lifts the current moratorium on uranium mining.

The PEA investigated several mining and processing methods for Cole Hill and determined the mine should be an underground, sublevel stoping operation, tapping into 3,000 tonnes of ore daily. Alkaline leaching would then recover 83% of the uranium contained in the ore.

To build the mine should cost US$203 million, including a 25% contingency.

Current resources support a 35-year mine life for a Coles Hill mine, during which time the operation would produce 2 million lbs. U₃O₈ annually at an average cash cost of US$36.83 per lb. Based on a uranium price of US$65 per lb. and a 7% discount rate, the project carries a net present value of US$404 million and should generate a 36.3% internal rate of return. The mine would pay back the initial capital investment in less then three years.

Coles Hill is home to two uranium deposits. Both deposits continue to surface, which means their upper portions are amenable to open pit mining. Minable zones below open pit depths are generally continuous for more than 35 metres vertically. Because of this continuity, primary stoping should extract 70% of the resource while pillar retreat should recover another 20% of the deposit.

At present the resource stands at 34.2 million measured and indicated tonnes grading 0.103% U₃O₈, for 77.4 million lbs. contained uranium oxide. Virginia Energy says it expects to grow that resource, as much of the historical drilling only targeted mineralization at open pittable depths; both deposits remain open at depth. In addition, the deposits remain open along strike. That includes the area between the zones, which was historically protected by mining leases that prevented surface exploration so as to preserve the Coles Family homestead. Now the company says that, with the decision to pursue underground mining, it will consider exploration drilling in the protected area for underground tonnage.

As for the moratorium on uranium mining in the state of Virginia, there has recently been some forward progress. The state government has engaged the National Academy of Science to complete a study on the safety of uranium mining for the state, which should be complete by the end of 2011. If the study’s conclusions are positive towards mining, the state would be in a position to consider lifting the moratorium.

Virginia Energy certainly provided some positive incentive for such a move with its Coles Hill PEA, saying the mine would sustain some 325 permanent jobs and would contribute millions to the county government. The company also pointed out that roughly 37% of the power generated in Virginia comes from nuclear reactors, which cumulatively consume 1.7 million lbs. U₃O₈ each year. As such a Coles Hill uranium mine could allow the state to become self-sufficient with respect to its nuclear fuel requirements.

The PEA results gave Virginia Energy a healthy lift: the company’s share price added 9.5¢ or 33.3% to reach 38¢, a new 52-week high. The company’s year-long low is 14¢. Virginia Energy has 77 million shares outstanding.
