The DEF Grid 2 occurrence is located about 66 kilometres southeast of Fernie and about 1 kilometre south of Sage Creek.

The area is mapped regionally as being underlain by siltstone, argillite, and quartzite of the Helikian Creston Formation, Purcell Supergroup. Mineralization marked at DEF Grid 2, is likely similar to that reported in the area, which is stratabound chalcocite, chalcopyrite, and bornite as disseminations within quartzite horizons. Malachite staining is common on weathered surfaces. Bornite and chalcopyrite also occur in patches and as veinlets in quartzites.

WORK HISTORY

In 1970, Strato Geological Ltd., on behalf of Mark V Mines Ltd and Thor Explorations Ltd., carried out a reconnaissance silt and soil geochemical sampling and prospecting survey on their ABC, DEF, GHI, and JKL claims (Assessment Report 2746). A total of 31 rock, 28 stream silt and 60 soil samples were collected for analysis High copper values in silts were found in the areas of claim ABC 29 (082GSE054), ABC 17, and DEF 35, The latter are correlated with, and explained by a copper occurrence found during the 1971 program on Grid #2.

In 1971, soil geochemistry and geological mapping was completed and approximately 240 samples were collected on behalf of Mark V Mines Ltd and Thor Explorations Ltd. Several anomalous zones were indicated on the ABC, DEF, GHI, and JKL claims (Figure 3, Assessment Report 3336).

In 1972, Mark V Mines Ltd. extended the geochemical work was extended on the company's Sage Creek property. The claims involved were the ABC 1 to 4, and ABC 11 to 34. The soil sampling results revealed four soil new anomalies, in addition to an extension of the 1971 Grid #3 soil anomaly (ABC 16, 082GSE100) (Assessment Report 3931).
