The Bon 22, 24 showing is located on a ridge in the southern head waters of Friendly Creek, a tributary of the Bonanza River, north of the Nimpkish River. It is one of several which occur along a 1.2 kilometre mineralized zone striking about 285 degrees. This showing encompasses sample numbers 2150 to 2154 which were collected over a distance of 380 metres (Geology, Exploration and Mining in British Columbia 1970, page 277).

The area is underlain by andesites and basalts with minor inter- bedded limestone of the Upper Triassic Karmutsen Formation (Vancouver Group). Granodiorite of the Upper Jurassic Nimpkish batholith, which is part of the Jurassic Island Plutonic Suite, intrudes the Karmutsen Formation volcanics. Locally, the granodiorite is epidote altered.

Locally, the andesite has been altered to garnet-epidote skarn which hosts lenses of massive magnetite or pyrrhotite. The magnetite lenses dip 30 degrees to the southwest (parallel to bedding?), range up to 2.4 metres in width and are cut by pyrite veinlets. A 1.8 metre wide pyrrhotite lens with minor magnetite and pyrite assayed 0.4 per cent copper (Geology, Exploration and Mining in British Columbia 1970, page 277). Disseminated magnetite and magnetite veins ranging up to 7.3 centimetres in width have been reported within andesite and in garnet-epidote skarn.

Copper values ranging from 0.78 to 2.5 per cent copper have been reported from this occurrence (National Mineral Inventory 092L7 Fe4). In 2008, rock sampling yielded up to 8.04 per cent copper (Assessment Report 30446).

Work History

During 1968 through 1970, Brettland Mines completed programs of prospecting, geological mapping, soil sampling, ground and airborne magnetometer surveys and 13 diamond drill holes, totalling 334.2 metres, on the area as the Bon claims. In 1980, Vanstates Resources completed a program of soil sampling on the area as the Big Mac claims. In 2007 through 2013, Homegold Resources completed programs of rock and soil sampling, air photo geological interpretation and a ground magnetometer survey on the area as the Bonanza River property.
