The Pit Creek showing is located just south of the BC-Yukon border near the Primrose River where granitic rock displays moderate to very strong fracturing, weak hydrothermal alteration and strong pyritization. A prominent colour anomaly covers the claim property which contains the Silt (104M 054), Pit Creek (104M 055) and Rio Creek (104M 056) occurrences.

The chief lithology underlying the property is Paleogene (Paleocene to Oligocene) alaskite to leucocratic quartz monzonite. This unit is medium- to coarse-grained, equigranular and deep brown to orange on weathered surfaces, due to the oxidation of very fine-grained disseminated pyrite. In contact with the granite on the northeast of the property is weakly fractured, grey, unaltered coarse-grained feldspar porphyry granodiorite. Middle Devonian paragneiss occurs to the southeast and Middle- and Late Cretaceous granites occur farther west and south. A strong fracture system was reported to occur over a 1 by 5.5 kilometre area over the 1978 Silt property.

Traces of fracture-controlled, disseminated and vein molybdenite are widespread over the property. At the Pit Creek showing, coarse blebs and streaks of molybdenite occur in fractures and as disseminations over a 6 by 3 metre area. Sphalerite, galena, chalcopyrite, fluorite and cassiterite also occur along the southern margin, mostly associated with fracture zones and quartz veinlets. See Rio Creek (104M 056) for location of these polymetallic sulphides.

Molybdenite occurs in four habits:

a) as medium to coarse disseminations in granite;

b) as medium to coarse blebs along fractures;

c) as coarse blebs and rosettes lining and within quartz veinlets;

d) as very fine blebs and streaks lining microfractures.

The outer limits of molybdenite mineralization were not met in the area examined in 1978. All showings observed were within rusty granite, but many boulders of unaltered, non-ferruginous molybdenite-bearing intrusive rock were seen in creek bottoms.

WORK HISTORY

Kennco Explorations, (Western) Limited reportedly carried out a regional geochemical survey over the area in 1965 and examined some of the showings. Canadian Super Exploration Limited held the ground in 1970 as the Sue group and some work was apparently done by Archer Cathro & Associates Ltd. The area was staked by J. Hansen of Atlin , B.C., 1978 and was reported to be held by Pinto Resources Ltd. of Vancouver (Assessment Report 7336). The claim area was prospected and mapped geologically in early August and a number of geochemical samples were collected, including bulk stream sediment samples for heavy mineral studies. During 1978, Pinto documented mineralization on Silt prospect (Main showing) (104M 054), Pit Creek (B showing) (104M 055) and Rio Creek (Fracture zone) (104M 056). A high of 9580 parts per million (0.96 per cent) molybdenum and 60.3 grams per tonne silver were derived from a heavy mineral sample using a 20-35 mesh sieve (Assessment Report 7336).

In 1980, Orex Mines Ltd., a private company owned by M. and L. Jorgensen of Vancouver, was incorporated in order to acquire the property. Helgena Mines Ltd. optioned the claim from Orex in December 1980.
