The Top occurrence is located near the north shore of Chuchi Lake, approximately 5 kilometres east-southeast of the lakes west end.

Regionally, the area is underlain by undivided volcanic rocks of the Lower Jurassic Chuchi Lake Formation (Takla Group), which have been intruded by quartz monzonite to monzogranitic intrusive rocks of the Lower Jurassic Hogem Batholith.

Locally, several small occurrences of chalcopyrite, pyrite and possibly molybdenite along fracture surfaces in coarse-grained, equigranular monzonite, previously reported as a quartz diorite and diorite, are reported along an approximately 1 kilometre stretch of the north shore of Chuchi Lake. Alterations consists primarily of epidote.

Another zone of mineralization, comprising a quartz diorite porphyry with chalcopyrite and pyrite, is reported close to the west side of Little Witch Lake, approximately 1.5 kilometres to the north of the previous zones.

Work History

In 1971, Plateau Metals Ltd. completed a reconnaissance soil sampling program and a ground magnetic survey on the area as the Pot and Top claims.

In 1990 and 1991, BP Resources Canada Ltd. completed programs of rock sampling, a 39.0 line-kilometre induced polarization survey and a 207.0 line-kilometre airborne geophysical survey on the area as the Anom 1-5 claims. A rock sample (101009) from an outcrop of potassic feldspar megacrystic monzonite porphyry with pyrite along fractures, located on a small hill east-southeast of Little Witch Lake, yielded 1.2 grams per tonne silver, 0.077 per cent copper and 0.027 per cent molybdenum (Assessment Report 21981).

In 2007, Solomon Resources Ltd. completed a program of geochemical (soil and silt) sampling and a 1458.4 line-kilometre airborne geophysical survey on the area as the Col-Magnet property.

In 2013 and 2014, Pacific Empire Minerals Corp., in conjunction with Nation River Resources Ltd. and Indata Resources Ltd., completed programs of rock and soil sampling on the area as part of the Col-Later-Klawback property.
