Wolf Minerals has received a positive definitive feasibility study (DFS) for its Hemerdon tungsten and tin project in the UK.

The project consists of a two-stage open pit, along with a 3Mtpa concentrator and associated infrastructure.

According to the study, the value of the project is £74m ($105m), with cash cost of $105/metric ton unit and has a mine life of ten years.

The ten-year DFS pit design is limited only by the approved planning permission and has the resource potential for the mine life to be extended by several years.

Wolf Minerals managing director Humphrey Hale said that, following the completion of the feasibility study, the firm is ready to commission the processing plant by the end of 2013.
