The Jay 2 occurrence is located at an elevation of approximately 1300 metres on the southwest flank of Skwilkwakwil Mountain.
The area is underlain by Border phase quartz diorites of the Upper Triassic to Lower Jurassic Guichon Creek Batholith (EMPR Map 30). Guichon variety rocks occur to the southwest. Rocks are cut by coarse-grained feldspar porphyry dikes up to 30 metres wide. Narrow pegmatite and occasional aplite dikes are also visible.
Minor disseminated bornite and chalcopyrite occur in narrow quartz-calcite veins close to feldspar porphyry dikes within a northwest-trending intensely sheared zone. Biotite, epidote and chlorite are common alteration minerals. Rock samples from the dump near the shaft are reported to be highly altered with blebs of chalcopyrite, bornite, pyrite, azurite and malachite (Assessment Report 6327). Trenching (eight trenches) has exposed the shear zone along a 200-metre strike length.
In a 1981 diamond drill program, drillhole number 3 encountered 0.9 metre of vein chalcopyrite and malachite in a siliceous section. Drillhole number 4 intersected 0.9 metre of 1.87 per cent copper and 0.9 metre of 1.29 per cent copper; whereas drillhole number 5 intersected 0.9 metre of 0.56 per cent copper (Assessment Report 9813).
In 2010, a dump (WVF-10-19) sample from the shaft yielded 2.82 per cent copper, 10.4 grams per tonne silver and 0.12 gram per tonne gold (Assessment Report 32025).
In 2014, a rock sample (WV14-R11) from the shaft assayed 0.459 per cent copper and 3.7 grams per tonne silver (Assessment Report 35321).
Work History
A historical inclined shaft and numerous trenches, dating to the first half of the 1900s, are reported on the occurrence.
In 1964 and 1965, Kamloops Copper Consolidated completed programs of soil sampling, geological mapping and ground magnetometer surveys on the area as the Jay claims. In 1969, Cominco completed a program of geological mapping, geochemical (silt and soil) sampling and an induced polarization survey on the area as the Highland Queen and Nes properties.
In 1973, Highland Chief Mines completed a program of soil sampling and a ground magnetometer survey on the area as the Egg claims. In 1977, a program of soil sampling and a ground electromagnetic survey was completed on the area as the Flex claim. In 1978, Flexible Resources completed a program of geochemical (rock, water, silt and soil) sampling on the area immediately south as the Ible claim. In 1979, a program of prospecting, soil sampling and a 2.1 line-kilometre ground magnetic and electromagnetic survey was completed the area immediately to the east and south as the GSE and Ible claims.
In 1981, Canadian Overseas Exploration completed six diamond drill holes, totalling 364.8 metres, on the Flex, Ible and GSE claims.
In 2007 and 2008, Appleton Exploration completed programs of prospecting and soil sampling on the area as the Clapperton property.
During late 2008 through 2012, Happy Creek Minerals completed programs of geochemical (rock, silt and soil) sampling, geological mapping, three diamond drill holes, totalling 740.9 metres, an induced polarization survey and a 1463.0 line-kilometre airborne gamma ray spectrometer and magnetic survey on the area as the West Valley property.
During 2013 through 2019, Happy Creek Minerals Ltd. completed programs of geological mapping, geochemical (rock, silt and soil) sampling, a 32.3 line-kilometre induced polarization survey and re-interpretation of historical airborne geophysical data on the area as part of the Rateria-West Valley property.
