The Archibald occurrence is located in the south eastern headwaters of Connel Creek, north east of Diorite Peak.
In the region, the Cadwallader and Ferguson faults transect sedimentary and volcanic rocks of the Mississippian to Jurassic Bridge River Complex (Group) and the Upper Triassic Cadwallader Group. Linear, altered serpentenite zones of the President Ultrabasic, correlative with Permian and older Shulaps Ultramafic Complex, mark faults that have controlled the emplacement of diorite of the Permian Bralorne Igneous Complex. The above sequence lies between bodies of the Jurassic to Tertiary Coast Plutonic Complex and outlying granodiorite of the Cretaceous to Tertiary Bendor pluton.
The Archibald quartz vein strikes from 120 to 130 degrees for about 800 metres, dipping 55 degrees southwest to 86 degrees north. Minor galena and pyrite were noted at the northwest end of the vein. The vein is hosted by listwanite-altered ultramafic rocks and diorite.
The area was originally explored by pits and trenches in the early 1930’s along with the nearby Silicon Ridge (MINFILE 092JNE156) occurrence. In 1983, X-Cal Resources completed a program of rock and silt sampling and geological mapping on the area as the Mac and X-Cal claims. In 1985, Hudson Bay Exploration and Development completed a program of geochemical sampling, geological mapping and a ground electromagnetic survey. In 1989 and 1990, Teck completed programs of rock, silt and soil sampling, geological mapping and a ground electromagnetic survey on the area as the Veegee property. In 1991, Cogema completed a program of geochemical sampling and geological mapping on the area. In 2007 and 2008, airborne ZTEM surveys were completed on the area. In 2009, a MMI soil sampling program was completed. In 2011, Worthington Resources Ltd. completed a 408.5 line-kilometre airborne ZTEM survey on the area as the Royalle property.
