Work History
Staked as Stone cl 1-8 (95209) in Dec/65 by Golden Gate Explorations Ltd which carried out airborne magnetometer surveying during Sep/66. Restaked as Kay cl (98192) in Jan/66 by A. Van Bibber, etc.
Restaked as Sue cl (YA74705) in Jul/82 by Kidd Creek Mines Ltd, which carried out grid soil geochemical sampling, horizontal loop EM and magnetometer surveying, geological mapping and hand trenching later in the year. The geophysical surveying was the only work reported on.
Restaked as Evan cl 1-4 (YC08963) in Jul/98 by Atna Resources Ltd, which added Evan cl 5-16 (YC17975) in Jul/99 and carried out geological mapping and geochemical sampling.
Capsule Geology
The occurrence is located in an overburden covered area underlain by chloritic and calcareous phyllite interbedded with cal-silicate hornfels and skarn. While this area has not yet been remapped, recent mapping to the southeast completed by the Yukon Geology Program (Pigage, 2001) suggests that the units in this area are probably correlative with the Upper Proterozoic to Cambrian Mount Mye Formation and the Cambrian to Ordovician Vangorda Formation.
The geophysical surveys delineated a northwest-trending fault, indicated that small folds and faults repeat horizons across the grid, outlined a few coincident magnetic anomalies and EM conductors, and traced magnetite and pyrrhotite-bearing horizons.
Lead-zinc-silver mineralization consisting of fine grained magnetite, sphalerite and galena with lesser amounts of pyrrhotite, chalcopyrite and pyrite occurrs as veinlets, pods and lenses within garnet-actinolite-chlorite silicate hornfels. The style of mineralization present in the area is suggestive of skarn development, although no causative intrusive has yet been identified.
Chip sampling of historical showings and trenches by Atna in 1999 returned 2.1% Zn, 1.5% Pb and 11.9 g/t Ag over 3 m, while grab samples returned values up to 6.1% Zn, 1.7% Pb and 39.8 g/t Ag.
