Work History

Early prospectors found showings here but the staking records have not been located. Re-staked in November 1969 by R. McKamey as Lo cl (Y40619), which were optioned to Samson ML and Monarch Metal ML in December 1969 and assigned to Yukon Revenue ML, which conducted soil sampling and trenching in 1970. Cominco staked COM cl (Y38156) 1.5 km to the northwest in September 1969 and performed soil sampling and mapping in 1970.

G. Harris staked Ken cl (YA82495) 1.5 km to the north in June 1984, performed mapping and geochemical sampling later in the year, and bulldozer trenching in 1985. Chevron Can Res L staked the EYM cl (YA86872) around the Ken cl in June 1985 and performed soil geochemical sampling later in the year and in 1986, then optioned the claims to Big Creek JV (Big Creek RL & Rexford ML), which performed minor road work in 1988.

R. Granger re-staked the Ken cl as the Nek cl (YA95968) in August 1986 and added additional claims in September 1986. The EYM claims were sold to Big Creek RL in spring, 1990. Archer, Cathro & Associates (1981) Ltd filed $6200 of rotary drilling on the EYM claims in March 1992.

The Combo occurrence is currently located within Triumph Gold’s (formerly Northern Freegold Resources) Freegold Mountain Project claim package. 

Geology

The claims lie along the Big Creek Fault and are underlain by Paleozoic metamorphic rocks, which are intruded by Jurassic Big Creek syenite and mid-Cretaceous porphyry dykes. The original showing was reportedly a lead-zinc vein.

Soil sampling outlined a weak tungsten anomaly on the Com group and moderate to strong gold-arsenic-silver anomalies on the EYM group.
