A 3 m long horizontal shaft of unknown date near the beach. The copper mineralisation occurs in a skarn, in the contact zone between a 4 m wide zone of calcite marble and migmatittic biotite gneisses, embedded in monzodioritic intrusives. The partly actinolite-altered pyroxene-garnet skarn zone is 30-50 cm wide, and is only exposed near the end of the shaft, and comprises disseminated and semi-massive pyrrhotite with varying amounts of chalcopyrite.

Two analyzed samples display copper values varying from 4688 to 13007 ppm.
