Background:

​

The Hemerdon Tungsten-Tin Mine, formerly known as Drakelands Mine or the Hemerdon Ball or Hemerdon Bal Mine, was an operating tungsten and tin mine between August 2015 and October 2018 under previous operators Wolf Minerals (UK) Ltd. (Wolf).

The mine is located 7 miles NE of Plymouth, near the village of Plympton, in Devon, England, and has been categorised as a world class deposit due to the scale of the deposit within a global context.

The mine site retains a partially developed open pit, a complete processing plant, an integrated mine waste facility, workshops, administration offices and all associated mine site infrastructure.

​

Geology:

​

The Hemerdon deposit is centered upon a sub vertical, NNE-SSW striking, 100+ m wide Early Permian   granite   dyke   hosted   by   Devonian   metasedimentary   and   metavolcanic   rocks. Mineralisation is overwhelmingly associated with moderately to steeply NW-dipping greisen-bordered quartz-ferberite± cassiterite sheeted veins. The resource size and dyke host are, to date, unique in SW England.
