Wolf Minerals (ASX: WLF) has been issued a much anticipated Category A Mining Waste Facility Environmental Permit for its Hemerdon tungsten and tin project in Devon, UK.
 
This key permit is the final major permit required to proceed with development and construction of the project.

Construction of the project is scheduled to begin in January 2014.

Hemerdon will have a 3 million tonne per annum tungsten and tin mineral processing plant plus associated infrastructure producing 345,000 mtu’s of tungsten trioxide in concentrates per annum and approximately 450 tonnes of tin in concentrates per annum.

It has also reached an offtake agreement for 80% of its tungsten concentrate output with Wolfram Bergbau und Hutten Ag of Austria and U.S-based Global Tungsten & Powders Corp.

The Hemerdon Project has a Proven and Probable Reserve of 26.7 million tonnes at 0.19% W03 (tungsten) and 0.03% Sn (tin). It is the third largest tungsten and tin deposit globally.

Wolf’s Definitive Feasibility Study had confirmed the project to be a robust low cost project with a cash cost of just US$105 per mtu.

Capital expenditure has been estimated at £104 million with NPV at £74 million. The project has an estimated payback of 3.25 years.
