The Enterprise occurrence is located in northwest British Columbia, approximately 90 kilometres northwest of Stewart.
The showing consists of malachite stained limonitic sponge in altered andesitic ash tuff or limy sediments near the intrusive contact of the Lehto pluton, a large monzodioritic stock that is locally characterized by very coarse K-feldspar phenocrysts.
Host rocks are provisionally assigned to the Stuhini Group (Upper Triassic) but may be Permian or older Stikine Assemblage.
Mineralization may be a product of contact metamorphism. However there are abundant thin to thick quartz veins in the marginal zone of the pluton that may be evidence of a later hydrothermal event.
Best assay from a grab sample returned 52.6 grams per tonne gold, 197 grams per tonne silver, 2.95 per cent copper, 0.0314 per cent lead, and 0.16 per cent zinc (personal communication with J.M. Britton 1990).
In 1989, a magnetite skarn (approximately 50 metres wide x 100 metres long) is exposed in the back of the bowl of a west-facing cirque on the Cam 4 claim. Exposure of the skarn is limited due to snow cover. The skarn mineralization consists predominantly of massive magnetite. Minor pyrite, in places forming massive pods to 0.5 metre wide, trace amounts of chalcopyrite and malachite on fractures were observed. No gold or silver values were obtained in any of the samples of this skarn except sample 54538 a sample of massive magnetite skarn that ran 2.48 grams per tonne gold (Assessment Report 19760).
Barite-chalcopyriite-malachite-bearing quartz vein float was noted at the 575 metre elevation in the L.C.P. creek (several hundred metres to the south of the magnetite skarn (above)) and subsequently traced upstream to its source. The vein structure is 1 to 1.5 metres wide, follows, and has subsequently healed, a shear that forms the contact between the quartz diorite to granodiorite intrusive stock to the east and limy sediments on the west. At lower elevations this vein contains local galena, sphalerite, chalcopyrite (plus or minus barite) mineralization; this vein bends to the east at upper elevations and the vein becomes barren (samples 89269 to 89274). Two sub-parallel shear veins were located 200 metres east of this vein, also cutting the granodiorite. These veins (to 2.5 metres wide) also carried local galena, sphalerite, chalcopyrite, pyrite and azurite; gold and silver values were low.
In 1987, an airborne EM and Magnetic survey was conducted over the Cam 1 and 4 on behalf of Northwest Gold Syndicate (Assessment Report 17129). In 1989, 5 silt, 139 soil, and 102 rock chip samples were collected by Corona Corporation on the Cam 1 to 4 claims (Assessment Report 19760).
Sampled in 1989 by BC Geological Survey field crew.
Limited rock sampling in 2015 by Colorado Resources Ltd. produced no significant results (Assessment Report 35943).
