The Kog 1 occurrence is located on the west side of a northeast-flowing tributary of McDame Creek, approximately 1.3 kilometres upstream from the creeks’ junction with McDame Creek.

Regionally, the area is underlain by a northwest-trending and southwest-dipping series of sediments comprising limestone, slate, siltstone and argillite of the Cambrian to Ordovician Kechika Group; quartzite and quartz arenite sedimentary rocks of the Silurian to Lower Devonian Ramhorn Group; limestone, marble and calcareous sedimentary rocks of the Middle to Upper Devonian McDame Group and mudstone and fine clastic sedimentary rocks of the Upper Devonian to Lower Mississippian Earn Group and Mississippian Slide Mountain Complex.

Locally, galena and sphalerite occur in a narrow (0.5 to 1 centimetre wide) seam in a sandy dolomite. A second area of mineralization is located approximately 800 metres north-northeast and comprises a 10-centimetre-wide shear zone in dolomite hosting galena and sphalerite.

In 1983, a grab sample from the first zone is reported to have assayed 5.9 per cent lead, 1.7 per cent zinc and 234 grams per tonne silver (Assessment Report 13424).

Work History

In 1983 and 1984, Canamax Resources Inc. completed programs of prospecting, geological mapping and soil sampling on the area as the Kog 1-3 claims.

During 2008 through 2010, Hawthorne Gold Corp., later China Minerals Mining Corp., completed regional programs of geological mapping and geochemical (rock and soil) sampling, and 11,657 line-kilometres of airborne magnetic, radiometric and electromagnetic surveys on the area as the Cassiar Gold property.

In 2019, Margaux Resources completed a program of prospecting, geological mapping and rock sampling on the area as the Cassiar Gold property. In 2020, Cassiar Gold Corp. completed a program of regional photogeological interpretation, prospecting and rock sampling on the Cassiar Gold property.
