Work History

The area has been covered by claims numerous times in the past but bedrock mineralization was not identified until Mortensen's mapping in the mid 1990's. Barimundi Gold covered the showing with the MF 1-52 (YB68265) claims staked in April and May of 1996. Mortensen (1996) reports this as occurrence #115 O157.

Capsule Geology

Bands of semi-massive pyrite up to 10 cm thick occur within rusty weathering quartz-muscovite schist and muscovite quartzite (unit Psqm) of the Permian Klondike Schist Assemblage in the bedrock of Quartz Creek. These rocks are interpreted as deformed felsic tuff and tuffaceous chert, and appear to form a screen or pendent within gnesisic biotite quartz monzonite of the Sulfur Creek orthognesis (unit Pqmg). The sulphides are thought to be syngenetic in origin. No base metal sulphides were noted but trace amounts of barite occur in some of the pyrite beds.
