The Perfect Storm (PSZ) occurrence is located at an elevation of approximately 1500 metres on an east-facing slope, adjacent to the western side of the retreating 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, gold-copper-silver porphyry-related mineralization associated with a large fault structure (Sulphurets thrust fault) has been identified by diamond drilling.

In 2020, drillholes PS-20-01 and -02, completed from the same drill pad, yielded intercepts of 0.483 and 0.514 gram per tonne gold over 133.5 and 151.0 metres (from 240.0 and 265.5 to 373.5 and 416.5 metres down hole), respectively, whereas a third drillhole (PS-20-03), located 300 metres to the southwest, yielded 0.293 gram per tonne gold over 220.5 metres (152.0 to 372.5 metres down hole); (P&E Mining Consultants Inc.

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 2020, Tudor Gold Corp. completed a program of diamond drilling on the Goldstorm (MINFILE 104B 704) and Perfect Storm zones of the Treaty Creek Gold property. Three diamond drill holes, totalling 1636 metres, were completed on the Perfect Storm zone.
