The Rod occurrence is located at an elevation of approximately 1360 metres on a small hill, approximately 1.5 kilometres east of Leroy Lake.

The area lies near the eastern border of the Upper Triassic to Lower Jurassic Guichon Creek Batholith. The area is underlain by coarse-grained quartz diorite to granodiorite of the Border phase, which grades westward to younger, medium-grained Guichon variety granodiorite of the Highland Valley phase of the batholith. To the east the intrusive rocks are in contact with sedimentary and intermediate volcanic rocks of the Upper Triassic Nicola Group. The contact strikes north and dips steeply and is marked by high-grade metamorphism.

The granodiorite is faulted and fractured with sporadic limonite staining. Chalcopyrite mineralization occurs in small amounts in fractures and as disseminations.

Another zone of mineralization is reported on the former Dot 22 claim, located east of Antler Lake and approximately 2 kilometres south of the Rod occurrence, and comprises trace malachite, chalcopyrite and molybdenite(?) in a pegmatitic stockwork. Minor malachite mineralization is also reported southwest of Antler Lake.

Work History

In 1956, Deerhorn Mines completed a program of geological mapping and soil sampling on the area as the Rod claims. Also at this time, Anuwon Uranium Mines completed a program of geological mapping and trenching on the Rod, Fiddler and FB claims. The following year, Shield Mining Surveys Ltd. completed a 15.0 line-kilometre ground electromagnetic survey on the Fiddler property.

In 1958, Northwestern Explorations Ltd. completed a program of geological mapping, soil sampling and a 128.0 line-kilometre ground magnetic survey on the area as the JB claims.

In 1964, Mamit Lake Mines completed a 7.5 line-kilometre induced polarization survey and a 22.2 line-kilometre ground magnetic survey on the area immediately south of the occurrence as the MLM claims. In 1967, a 3.4 line-kilometre induced polarization survey was completed on the MLM claims.

In 1968, King Resources Co. completed a program of geological mapping on the area as the Ant, In, Jay, Len, Rex, Rob, Sho, T.D.M. and Wiz-Dot claims of the Chataway property. Also at this time, Cannoo Mines completed a 16.0 line-kilometre induced polarization and self-potential survey on the area as the Aug and Cal claims.

In 1969, Bethlehem Resources Ltd. is reported to have completed several drillholes south of Dupuis Creek and near the northwest end of Mamit Lake.

In 1970, Anaconda American Brass Ltd. and Mamit Lake Mines Ltd. completed a 6.8 line-kilometre induced polarization survey, a 16.0 line-kilometre ground electromagnetic survey and a 14.0 line-kilometre ground magnetic survey on the area immediately east of the occurrence as the MLM claims. The following year, Mamit Lake Mines Ltd. completed a program of soil sampling and 30.8 line-kilometres of ground magnetic and electromagnetic surveying on the MLM claims.

In 1972, Teck Explorations completed a program of soil sampling and a 63.0 line-kilometre induced polarization survey on the area as the MLM property. Also at this time, a 1112 line-kilometre airborne magnetic survey was completed on the area as the MLM and GCM claims.

In 1981 and 1982, Cominco Ltd. completed induced polarization and ground magnetic surveys on the area as the MJC and Antler claims of the Gump property.

In 1999, Tarco Oil and Gas Ltd. completed two diamond drill holes, totalling 266.4 metres, on the area immediately east of the occurrence as the Roy 1-2 claims.

In 2008, Happy Creek Minerals Ltd. completed a 278.0 line-kilometre ground magnetic survey on the area as part of the Rateria property.

During 2009 through 2011, the area was examined by Highbank Resources Ltd. and Moag Copper-Gold Resources Inc. as the Highland Valley property. Programs of geological mapping, soil sampling and an induced polarization survey were completed during this time.

In 2013, Christopher and Guy Delorme completed a photo-geological interpretation program on the area as the Bertha property.

In 2018 and 2019, Granby Gold Inc. completed programs of geological mapping and soil sampling on the area as the Mamit Lake property.
