Capsule

Work History

Staked as 200 Ram, etc cl in Nov/70 following a reconnaissance geochem program by Great Horn Mg Synd Inc, which explored with mapping and soil sampling in 1971.

Capsule Geology

The claims were staked over tungsten, copper and zinc stream sediment anomalies associated with skarn that has developed in limy Triassic rocks at the contact of a granite-quartz monzonite stock. A chip sample from one skarn zone 3 m wide assayed 4.1% WO3 and 2.5% Cu.
