Scheelite-bearing quartz, garnet, diopside and vesuvianite bearing skarn which covers an area of 50 x 120 meters. It was open-pit mined for tungsten by Dimac Energy in 1981-1982.

The Dimac tungsten skarn is associated with a two-mica granite, is characterized by scheelite but carries virtually no sulphides except rare pyrrhotite. This extremely coarse grained garnet, vesuvianite and scheelite suggests it developed in a reduced, low-sulphur system. The crystals indicate that the skarn formed at a deep level and crystallized over a considerable length of time. (Webster, Ray and Pettipas 1991)
