Capsule

Work History

Staked as I cl (YA44353) in Jun/79 by Klinkit JV (DuPont of Can EL and Duval Corp), which performed mapping and geochem surveys later in the year. The staking was prompted by a silt anomaly identified by the GSC. 
Restaked as TB cl (YA57372) in Feb/81 by McPres Ml EL and optioned to Player Pet L, which performed mapping and trenching later in the year. 
In Oct/97 Birch Mountain Resources Ltd staked Rhy cl 1-94 (YB90735) 4 km to the east.

Capsule Geology

The anomaly is derived from a hydrothermally altered gossan within Carboniferous(?) quartz monzonite of the Ram Stock. Pyrite, chalcopyrite, molybdenite and minor scheelite and powellite occur along fractures and in quartz veins. A chip sample from a trench in the best mineralization returned 0.6% Cu, 27.4 g/t Ag and 0.03% W.
