Work History

The area around the Ruth occurrence was first staked in Sept/1953 within the Sunrise cl 1-2 (66617), Lady Luck cl 1-4 (66619), Grizzlie cl 1-4 (Y66623), Eagle cl 1-3 (Y66627) and Jackie cl 1-3 (Y66630) group of claims. It was restaked later as the Dorothy cl 1-2 (90441) and Nayda cl 1-2 (90445) in Jul/64, as Oscar cl 1-104 (Y25217) in Jul/68, as Ruth cl 1-16 (Y59831) in Dec/70, as Lake cl 1-12 (Y67045) in Aug/72, and as Zeus cl 1-5 (YC08019) in Jul/97. The claims lapsed and the property was staked in 2005 as the Cuprum and then again as MISTY in Feb/2011. Currently, the claims are staked as the HS.

Work on the Ruth occurrence in the past has included trenching, ground geophysics, prospecting, and soil and rock geochemistry.

Geology

The Ruth occurrence lies within the Intermontane Belt of Yukon and is underlain by rocks of the Stikinia Terrane. The occurrence occurs on the near the contact between the Lewes River (limestone) group and the Ruby Range intrusive group. The occurrence is within the Whitehorse Copper Belt which has a long history of copper mines along the belt.

The carbonate rocks are highly altered to calc-silicate and hornfels with massive magnetite-sulphide mineralization in large pods within the altered rocks and as disseminated mineralization. The largest skarn zone measures 9 to 30 m wide, strikes north and dips about 25° east. It has been intermittently outlined in outcrop for a length of 760 m. Representative samples assayed from 0.3% to 17% Cu but the overall grade is estimated to be less than 1% Cu.

A specimen collected in 2011 returned 2.1 g/t Au, 1% Cu, and 55 g/t Ag.
