Work History

Staked as Mr cl 1-4 (89361) in Sep/65 by P. Risby.
Restaked in Oct/77 as Hawk cl 1-8 (YA26737) by A. Black and optioned in Nov/77 to Union Carbide Canada Ltd. The company added Hawk cl 9-16 (YA28133) later in the month and carried out a geological mapping and soil sampling program in May/78 before dropping the option.
The six surviving Hawk claims were surround by a large block of Klunk claims (460 claims total, claim #223 = YA53941) in Mar/80 by Cyprus Anvil Mining Corporation which optioned the Hawk claims and performed geological mapping and geochemical, magnetic and EM geophysical surveys later in the year.

Capsule Geology

The area is located approximately 20 km northeast of the junction of the Robert Campbell Highway and Nahanni Range Road. The area was mapped at 1:250 000 scale by Blusson (1965). Gordey and Makepeace (2003) released a geological compilation of the Yukon which further interpreted the geology of Frances Lake area.
According to Gordey and Makepeace the area is underlain by Upper Devonian to Mississippian clastic sedimentary rocks assigned to the Earn assemblage. The Earn assemblage overlies Silurian to Middle Devonian limestone and calcareous clastic sediments assigned to the McEvoy Platform. The Earn assemblage represents the western edge of the Selwyn Basin while the McEvoy Platform is a high-standing block located west of the Selwyn Basin that is believed to represent an eastern-most, autochthonous part of Cassiar Terrane. Thus it appears the area is located on the overlapping boundaries of the Selwyn Basin and Cassiar Terrane. The mid-Cretaceous Mt. Billings Batholith intrudes the area to the north.
Black staked the Hawk claims to cover anomalous scheelite and black sands found in a small gully while prospecting for gold. Follow-up exploration carried out by Union Carbide determined that the anomalous scheelite values resulted from concentration during glacial transport and the original source could not be determined.
Cyprus Anvil examined the six surviving Hawk claims for their lead-zinc potential, as part of a larger exploration program carried out on the adjoining Klunk claims. Soil sampling results were all within background values and the geophysical surveys failed to detect any conductors. Prospecting failed to uncover any mineralized showings.
