Acanthite (silver sulphide) and stromeyerite (silver-copper sulphide) occur as veinlets, stringers and lenses in the High Grade and No 3 vein, giving rise to bonanza style grades.
The second mineralization type contains native silver, argentite-acanthite, stromeyerite, and possesses high silver values with generally low lead and other base metal grades.
The No 3 vein appears to strike into the former Silver Mask claim (present Stromeyerite claim owned by Mountain Boy) which appears to have similar high grade mineralization.
