Work History

No specific claim records have been found but old hand pits are present and about a dozen copper claims were staked in the vicinity of Fifty Mile Creek in 1899-1900 by H.E. Porter. 
Staked as Mol cl 1-36 (Y56573) by Moly-Ore Mines Ltd in Apr/70 but no work was done. Restaked as Tony cl 1-10 (YB4073) in Sep/87 by Croesus Resources Incorporated, which transferred the claims to Walhalla Exploration Ltd in May/89.

Capsule Geology

Calcareous units within Nasina Assemblage schist (unit DMs) is altered to skarn near Lake Cretaceous granodiorite intrusions (unit lKgdr). Evidence of old workings, most of which expose traces of malachite in skarn, can be found along a zone some 300 m in length.
