Work History

Staked as Vanguard cl (13258) in Jul/20 by A. Nicol, who carried out trenching and shafting: surveyed the claims and took them to lease; shipped 11.6 tonnes of hand-cobbed ore in 1934; and shipped a further 31.8 tonnes of ore in 1948-49.
Optioned to Canex Exploration Ltd in Oct/50; to Amco Exploration Inc from Jun/52 to Feb/53; and to C. Warm in 1962, who carried out 91.4 m of cross-cutting in 1962-63.
The Vanguard claim and a number of adjoining claims, including the Quest cl (56622) and Quill cl (59273) to the east, were acquired by Canada Tungsten Mining Corporation Ltd in Mar/79. Canada Tungsten carried out prospecting, geological mapping and geochemical rock sampling of the claims in Jun/79.
Ownership was transferred to Springmount Operating Company Ltd in 1987.

Capsule Geology

Silver-lead-zinc mineralization in the Elsa-Keno Hill mining camp occurs in north-northeast to east-northeast striking, steeply southeast dipping vein-faults located within a 23 km long by 6 km wide northeast trending belt of rocks on the south dipping limb of the McQuesten Antiform. The mineralized vein faults cut Devonian to Mississippian Earn Group phyllites, Mississippian Keno Hill quartzite and minor phyllite and Triassic meta-diorites. The vein-faults, are brittle displacement zones that show complex variations in style along their length. Narrow discrete planar fault segments pass into zones of tensional veining or shattered rock, brecciation and stockwork veining. The richest deposits occur in the vein-faults which cut the Keno Hill quartzites.
The Vanguard vein is a typical transverse vein-fault which cuts Keno Hill quartzite. Mineralization consists of galena and tetrahedrite in a carbonate gangue, with the ore grade material developed immediately above a flat lying fault of unknown offset. The grade of the ore from this vein is reported as 8 159.8 g/t Ag and 65% Pb for 1934 shipment and 10 285.4 g/t Ag and 51% Pb for the 1948-49 shipment.
Canada Tungsten reported that the adjoining claims were also underlayen by Keno Hill quartzite and that unmineralized white bull quartz veins up to 15 cm wide were widespread on the Quest claim. On the southeastern portion of the Quill claim, a small pit and a yellowish colored gossan zone in an outcrop of quartz-sericite schist was sampled for gold, but the assay results were not available at the time the company reported on the work in 1979.
