Work History
The main showing was found prior to 1935 although no staking records or work history have been located. Staked as Farmu cl (73127) in Aug/57 by Gavin Muir and restaked as JH cl (YlO954) in Nov/66 following an airborne mag and EM survey by Glenlyon ML, which conducted soil sampling and ground EM surveys in 1967 and optioned the property in early 1968 to McIntyre Porcupine ML, which drilled one hole (167.6 m) later in the year.
Restaked as End cl (Y91534) in Nov/74 by Bow River Res L & Envoy Res L, which conducted geochemical and geophysical surveys in 1975; and as PDQ cl (YA25375) in Aug/79 by Welcome North ML. The PDQ group was transferred in 1980 to Pelly Project (Welcome North ML and E & B EL), which conducted airborne mag and EM surveys, linecutting and geochem sampling.
Capsule Geology
The Farmu claims were reportedly staked on an ultramafic body although none has been mapped at this location. The main showing is exposed on a small bluff and consists of pyrite and chalcopyrite in a quartz stockwork cutting phyllite and sericite-chlorite schist. Glenlyon found similar mineralization in silicified, ferruginous dolomite and collected two representative chip samples 450 m apart, across widths of 3 to 7.6 m that averaged about 0.18% Cu, 6.9 g/t Ag and trace Au. The drill hole tested the main showing and it intersected numerous zones of chalcopyrite associated with quartz veining. The most continuous mineralization was from 2.4 to 7.3 m, which averaged 0.15% Cu and 0.15.4 g/t Ag while the best grade was 1.41% Cu, 24.0 g/t Ag and 0.34 g/t Au from 96.0 to 97.2 m.
Envoy discovered mineralized float near the main showing from which two representative samples of 50 fragments each assayed 0.75% and 0.57% Cu. Soil sampling failed to extend the known showings. The 1980 surveys gave negative results.
