The Pig occurrence is located at an elevation of approximately 1050 metres on a small hill north of East Earhorn Creek and approximately 3.8 kilometres northeast of the creek’s junction with Earhorn Creek.
The area is underlain by fine to coarse clastic sedimentary rocks of the Jurassic Nechako and Ashman formations, volcanic rocks of the Jurassic Naglico and Nechako formations (all Hazelton Group) and undivided volcanic rocks of the Jurassic Fawnie volcanics (Bowser Lake Group). Late Cretaceous to Miocene stocks and plugs intrude the strata.
Locally, an outcrop of schistose andesite, later described as a conglomerate hosting a pyritized shear zone, contains anomalous values of gold and mercury. The schistosity/shearing is reported to strike 134 degrees and dip 80 degrees north.
Work History
In 1984 and 1985, Lac Minerals Ltd. completed a program of rock and soil sampling on the area as the Pig 1-2 claims. A rock sample (84R-438) assayed 0.180 gram per tonne gold (Assessment Report 14939).
In 1986, Lac Minerals Ltd. completed a further program of geochemical (heavy mineral, rock, silt and soil) sampling and 40.0 line-kilometre ground electromagnetic survey on the Pig 1-5 claims.
In 1987, Lac Minerals Ltd. completed a 9.4 line-kilometre induced polarization survey on the Pig claims. This work identified a strong area of chargeability in the area of the occurrence.
In 1988, Lac Minerals Ltd. completed a program of test pitting and four rotary drill holes, totalling 189.6 metres, on the claims. Only two holes penetrated to bedrock. Hole RCP88-1 intercepted limonite-hematite–stained argillites and arenaceous siltstone with quartz veining and disseminated pyrite yielding 0.15 and 0.13 gram per tonne gold over 7.62 and 9.14 metres, respectively (Assessment Report 18487).
Also in 1988, Noranda Mining and Exploration Inc. completed a program of geochemical (heavy mineral, rock, silt and soil) sampling and geological mapping on the area immediately north and east of the Pig occurrence as the NR 1-7 claims. A float sample (31342) of andesite with hematitic quartz veinlets, located approximately 1.5 kilometres east of the Pig occurrence, assayed 0.08 gram per tonne gold, 0.064 per cent copper and 15.4 grams per tonne silver, whereas heavy mineral concentrates yielded up to 1.40 grams per tonne gold and visible gold flakes were obtained from Schjelderup Creek to the north of the occurrence (Assessment Report 17697).
In 2013, Amarc Resources Ltd. completed a 325.0 line-kilometre airborne magnetic survey on the area as the Azmo 1-8 claims of the Darwin property.
