The B-418 occurrence is located on south facing slopes of Kishinena Ridge, approximately 1 kilometre northwest of Starvation Lakes.
The area is underlain by undivided sedimentary rocks and dolomitic carbonate rocks of the middle Proterozoic Creston, Kitchener Formation (Purcell Supergroup). Locally, quartzite and green argillite host galena mineralization as small veins running parallel to the bedding, and as disseminations. In 1975, two outcrop samples (B-418 and B-421) yielded 2.30 and 1.22 per cent lead with 0.80 and 0.20 per cent zinc, respectively (Property File - Aquitaine Co. of Canada Ltd. [1976-02-02]: Report on Southeastern British Columbia Project 1975 for Aquitaine Company of Canada).
WORK HISTORY
In 1969, Akamina Minerals Ltd. conducted a regional mapping, and geochemical program on the Grinnell Formation, a section of which underlies the claims held by Mark V and Thor. Widespread occurrences of copper mineralization were located in the Grinnell and neighbouring formations. Some of these were trenched. Most of the resulting assays appear to have been in the 0.2 to 0.9 per cent copper range, with occasional grab samples assaying up to 5 per cent copper (Property File Document 810672). The mineralization is reported to have occurred as disseminations and fine fracture fillings in quartzite beds, in shales, and to some degree in dikes and quartz vein material.
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 which extended from the area north of Sage Creek to the southeast across Kishinena Creek and further south to within 1 kilometre of Starvation Creek (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 17 and DEF 35, the latter are correlated with, and explained by a copper occurrence found during the 1971 program on Grid #2.
In 1970, a geological report on the Langemark Group Sage Claims Nos. 5-16, 42, 44, 46 was completed on behalf of Falconbridge Nickel Mines Ltd (Assessment Report 2749). The claims were centred on Langemarck Mountain and may have been an overstaking of some of the ABC claims.
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). The JKL claims covered the area of K-19 (082GSE075), Starvation Creek and King Ed.
In 1972, Mark V Mines Ltd. extended the geochemical work 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 (Assessment Report 3931).
In 1975, rock samples K-19 and K-21 yielded 2.00 and 1.54 per cent copper, respectively (Property File - Aquitaine Co. of Canada Ltd. [1976-02-02]: Report on Southeastern British Columbia Project 1975 for Aquitaine Company of Canada).
In 1975, Aquitaine Co. of Canada Ltd. completed a program of regional geochemical sampling, geological mapping and prospecting on the area.
