Work History

Staked as the Homestake (7144) and Sunday (7147) claims by E. Tyndall and J. Rehn in Aug/05. Restaked many times, most recently as Crazy cl (YA79611) in Oct/83 by Eastern ML, which explored with mapping, sampling and an airborne EM survey in 1984 and mag, VLF-EM and geochem surveys and drilling in 1986. The Crazy claims were transferred to Kennecott Canada Inc. in May/93 as part of an option agreement.

Capsule Geology

The immediate area is underlain by locally sheared, weakly foliated to massive greenstone of the Anvil Allochthonous Assemblage. A vein of steel galena was exposed in a roadcut during construction of the Klondike Mines Railroad. An assay of an 18 kg rock chip of vein material is reported to have assayed about 17.3% Pb, 2% Cu, 582.8 g/t Ag and trace Au. No dimensions are available for the vein.
