The SW occurrence is located at an elevation of approximately 1700 metres on a roughly south-facing slope, adjacent to the north-northwest side of the receding Treaty Glacier.

The area is thought to be underlain by an andesitic succession of the Lower Jurassic Betty Creek Formation (Hazelton Group). Rocks in the area include weak to moderately altered crystal-lithic andesite tuffs; intensely altered crystal-lithic andesite tuffs (sericite schist); dolomite; limestone; quartzite; pillow lavas; red, purple and green volcanic breccias; porphyritic flows and minor chert. The Hazelton strata are in contact with Upper Triassic Stuhini Group rocks within several hundreds of metres to the west. The strata are intruded by Lower Jurassic diorite and feldspar porphyritic stocks.

Locally, an altered zone hosts gold values.

Seven rock samples from the altered zone are reported to have yielded from 0.211 to 1.770 grams per tonne gold (P&E Mining Consultants Inc. [2021-04-23]: Technical Report and Initial Mineral Resource Estimate of the Treaty Creek Gold Property, Skeena Mining Division, British Columbia, Canada).

Work History

The area has been explored in conjunction with the nearby Copper Belle (MINFILE 104B 518) occurrence and a completed regional exploration history can be found there.

In 1988, a minor soil and rock sampling program is reported to have been completed on the area, and three diamond drill holes were completed in 1997.
