Hemerdon tungsten/tin mine, UK


Name of the Project
Hemerdon tungsten/tin mine.
Location
Devon, UK.
Project Owner/s
Mining company Tungsten West.
Project Description
Hemerdon is a construction-ready, fully permitted, world-class tungsten resource, with significant tin and premium aggregate co-products. The project has the potential to generate more than 20% of tungsten supply outside of China.
The project has a base case 11-year life-of-mine (LoM), four years of subsequent stockpile reclaim and an additional 12 years of ongoing premium aggregate sales.
Total proven and probable reserves are estimated at 70.7-million tonnes grading 0.15% tungsten and 0.03% tin, for a total of 10.3-million metric tonne units of contained tungsten.
Total LoM production is estimated at 4.6-million metric tonne units of tungsten and 6 442 t of tin. Steady-state production is estimated at 332 000 metric tonne units of tungsten and 462 t of tin.
There is further scope for the extension of the current openpit towards the north and south through the Hemerdon Futures project, whereby the company plans to extend the current operations along the already defined Joint Ore Reserves Committee-complaint resource, which remains open at depth and along strike in a southern direction.
The project is expected to extend the total operational life, including stockpile reclaim and premium aggregate sales, to more than 40 years.
