The Teslin Lake occurrence is located along the east shore of northern Teslin Lake, 2 kilometres south of the Yukon border, and about 87 kilometres northeast of Atlin.
Along the east shore of northern Teslin Lake, 2 kilometres south of the Yukon border, a series of mafic to felsic tuffaceous rocks, quartz sericite schists and siltstones are exposed along a kilometre-long section of lakeshore. All are phyllitic to schistose and relict textures are rare. Several zones display widespread pyrite and traces of chalcopyrite. For example, at the south end of the outcrop belt a 20 metre thickness of locally strongly pyritic felsic metatuff is sandwiched between mafic metatuff. The gossanous layers are up to 30 centimetres thick and typically contain 10 per cent or more pyrite. Chalcopyrite occurs as sparse centimetre-sized clots and irregular stringers. It is evident at several localities that the zone has been previously sampled. Analysis of a single grab sample yielded 2.2 per cent copper and 28 parts per million (28 grams per tonne) silver (Fieldwork 1997, page 6-17).
In 2007, an airborne VTEM geophysical survey was flown on behalf of Strategic Metals Ltd. totalling 354 line kilometres. In addition, three soil sample lines were oriented to cross the stratigraphy.
