The Columbia (Scorgie) occurrence is located 1.4 kilometres northwest of Perry Creek at an elevation of approximately 1700 metres, approximately 300 metres above the valley floor.
The area is underlain by sedimentary rocks of the middle Creston Formation intruded at their (faulted) contact with Kitchener Formation by diorite sills of the Moyie Intrusions; all these units belong to the mid-Proterozoic Purcell Supergroup.
The main showing consists of a large quartz zone, up to 15 metres wide, containing irregular and low-grade disseminations of pyrite on the hangingwall; to the southeast, a zone of sheared rock with narrow veinlets of quartz carrying mostly irregular lenses of pyrite with some chalcopyrite and galena is present. The veins are hosted in sedimentary rocks of the Creston Formation (banded quartzite with argillite partings) intruded by dioritic dikes of the Moyie Intrusions, both mid-Proterozoic Purcell Supergroup. The diorite is pervasively altered to chlorite and a stockwork of quartz veinlets occurs in places.
Assays of material from the Scorgie tunnel range from 0.35 gram per tonne gold over 1.8 metres to 27 grams per tonne gold over 0.4 metre, averaging approximately 1.7 grams per tonne gold over 1 metre. In the Columbia shaft, assays range from 0.35 to 8.6 grams per tonne gold over widths of 1 to 1.5 metres, averaging near 3 grams per tonne over 1 metre (Property File-Report by W.V. Smitheringale, August 1932).
In 1981, a sample (49143) from the Columbia shaft assayed 5.1 grams per tonne silver and 4.7 grams per tonne gold (Assessment Report 9850).
In 1983, a dump sample (47142) assayed 1.0 gram per tonne gold (Assessment Report 11802).
In 1984, a grab sample (83177) from old workings assayed 5.35 grams per tonne gold, 9.8 grams per tonne silver and 0.316 per cent lead (Assessment Report 13007).
In 1986, a rock sample (CS-29/1629H) of sheared limonitic quartz in siltstone with pyrite from a former shaft assayed 14.0 grams per tonne gold (Assessment Report 15649).
In 1987, trench samples (No.64) from the Columbia shaft area yielded up to 12.6 grams per tonne gold, while a rock sample (14504) assayed 0.128 per cent lead, 22.4 grams per tonne gold, 4.2 grams per tonne silver (Assessment Report 17514).
The area was originally explored in 1915 with programs of trenching and drifting on several shafts on the Homestake claim group, including the Homestake (MINFILE 082FSE012) occurrence to the north. The Columbia occurrence past workings consisted of the Scorgie tunnel and Columbia shaft, with attendant open-cuts. In 1932, the Homestake property was held by Cranbrook Gold Mining Company and a program of drifting was completed.
In 1978, Meridian Resources completed a program of geochemical sampling and geological mapping on the area as the Luke group. During 1979 through 1985, Gallant Gold Mines completed programs of rock, soil and silt sampling, trenching, geological mapping and ground electromagnetic and magnetic surveying on the area as the Perry Creek property. In 1987, Chapleau Resources completed a program of soil, silt and rock sampling, trenching and geological mapping on the area as the Racki claims, Morgan property. In 1993, a 3.2 line-kilometre ground electromagnetic survey was completed. In 1997, Madman Mining soil sampled the area. In 2001 and 2002, National Gold Corporation completed programs of geological mapping and rock sampling on the area immediately west as the HS and Zinger claims. In 2003, Chapleau Resources conducted an extensive exploration program of surface prospecting, rock and soil sampling and geological mapping on the area as the Zinger property. In 2016, West Gold Corp. completed a program of prospecting, rock sampling and geological mapping.
