The JPG 1 occurrence is located approximately 9 kilometres southeast of Merritt, on the north side of a small hill between Godey and Hamilton creeks.
The western belt of the Upper Triassic Nicola Group consists mainly of an east-facing sequence of calc-alkaline flows grading upward into pyroclastics, epiclastic sediments and abundant limestone, separated from the central belt by a northeast-trending regional fault. Local lithologies are dark-green to grey, massive to plagioclase porphyritic andesite, andesitic breccia, tuff and interbedded grey, massive to cherty fossiliferous limestone. Bedding strikes northeast and dips steeply to the southeast. Some folding is indicated. A northwest-trending fault and north-northeast–trending shear and fracture zones dominate the central portion of the JPG 1 showing. Alteration is mainly epidotization and chloritization.
Mineralization is controlled by structural features. Showings consist of an old, inclined shaft, trenches and open cuts, which expose three parallel, north-trending zones varying in width from 1.5 to 6.1 metres and are traceable for up to 600 metres. Mineralization consists of native copper, chalcopyrite, magnetite, bornite, malachite, azurite, hematite and sphalerite in a gangue of plagioclase, hematite, quartz and calcite.
Work History
A historical shaft, of unknown age but likely dating to the 1930s, is report in the area of the occurrence.
In 1980 and 1981, MHB Resources Ltd. completed a program of geological mapping, trenching, soil sampling and ground magnetic and electromagnetic surveys on the area as the JPG claims. Samples (A and 1) from trenches on the JPG 1 claim is reported to have yielded up to 2.57 per cent copper and 3.3 grams per tonne gold (Assessment Report 9318 and 10483).
In 1982, four diamond drill holes, totalling 300 metres, were completed on the claims.
In 1995, Cambridge Minerals Ltd. completed an 834.0 line-kilometre airborne magnetic and electromagnetic survey on the area as the SK 1-16 claims.
In 2010, Navigo Ventures completed a program of geological mapping and a 22.1 line-kilometre induced polarization survey on the area as the LD property.
