The Nichol occurrence is located on Nichols Creek, approximately 11.8 kilometres north-northwest of its mouth on the Bridge River.
The region is underlain mainly by intrusive rocks of the Jurassic to Tertiary Coast Plutonic Complex, which here have intruded sedimentary and volcanic rocks of the Upper Triassic Pioneer Formation, (Cadwallader Group). These rocks are overlain in part by basalt of the Pleistocene Garibaldi Group. Sodic granite which forms part of the Mississippian to Jurassic Bridge River Complex (Group) also underlies the area.
The claims are underlain by sodic granite, hornblende quartz diorite and andesitic rocks. These rocks are cut by northwest- striking, steeply dipping fractures and shears. Locally, at least five mineralized veins have been identified by trenching and drilling, over an area of 600 by 400 metres. Mineralization comprises chalcopyrite and molybdenite in quartz veins and veinlets in a shear zone. Wallrock alteration is dominantly argillic, though some silicification and potassium feldspar alteration is also noted.
In 1981, a drill hole (79-S2) intercepted 8.4 metres yielding an average of 3.50 per cent copper, 0.029 per cent molybdenum and 34.2 grams per tonne silver (Assessment Report 10246).
In 2005, a grab sample (164607) from trench 4 assayed 7.65 per cent copper, 26.2 grams per tonne silver and 0.11 per cent molybdenum; another grab sample from trench 9 assayed 8.91 per cent copper, 33 grams per tonne silver and 0.043 per cent molybdenum (Assessment Report 28271).
The area was originally explored by Cominco in the 1930’s. An adit, 32.9 metres long and located at an elevation of 1865 metres, was completed during this time. In 1963, Phelps Dodge completed a program of geological mapping, soil sampling and a ground magnetic survey on the area as the Nichol claims. In 1981, Goldbridge Holdings completed eight diamond drill holes, totalling 380.7 metres, on the area as the Copper and CU claims. During 2005 through 2012, programs of prospecting, geochemical sampling, trenching and an induced polarization survey were completed on the area as the Copper 1-25 claims.
