No commencement date has yet been set for the start of the tungsten mining contract as Wolf is still tying up some remaining loose ends before the final go-ahead decision, but the company states that the formal commencement date for the work will likely be in March next year.

The contractor, CA Blackwell, primarily has experience in multi-disciplinary construction projects, although not in mining per se, with a past project emphasis on heavy earthmoving and reclamation work.

It was selected after Wolf received what it describes as eleven quality bids, with Blackwell being chosen on the basis of bid quality and price.  The contract value has come in close to the Definitive Feasibility Study estimate of £85.5 million (A$141 million1) announced back in May 2011.

China has the richest tungsten resources in the world, its tungsten ore reserves account for 58.95% of the global reserves and it provides the tungsten supply of about 85% for the global every year. In 2012, the new increased resource reserves of tungsten (WO 365%) were 200,000 tons and the output of tungsten concentrates (WO 365%) was 131,100 tons

The Blackwell contract is worth some £85 million ($A140 million) and will be in two phases.  Phase 1 will cover mining pre-strip and development tungsten mine, while Phase 2 is for contract mining to deliver ore to the plant. 

The contract term for Phase one is 11 months from the commencement date, followed by Phase 2 which has a five year term from completion of Phase 1 work.  

The Hemerdon mine, has a mineable ore reserve comprising a base case open pit at a cutoff grade of 0.063% tungsten of 26.7 million tonnes of proven .

And probable ore grading 0.19% tungsten and 0.03% tin within a JORC compliant resource of 401 million tonnes grading 013% tungsten trioxide and  0.02% tin which reportedly places it as the third largest known tungsten deposit in the world.
