The Rich 1 occurrence is located 12.5 kilometres east of the confluence of the Finlay and Firesteel rivers at the southern end of the Toodoggone gold camp, approximately 250 kilometres north of the community of Smithers. The Toodoggone gold camp lies within the eastern margin of the Intermontane Belt and is underlain by a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions. The Rich 1 showing is situated within a Mesozoic volcanic arc assemblage bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Stuhini Group andesite flows and pyroclastic rocks. Stuhini volcanics have been intruded by plutons and other bodies of the Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

Locally, the Rich 1 showing is underlain predominantly by lithologies of the Attycelley and Saunders members of the Toodoggone Formation. Non-welded lapilli-ash tuff, subordinate lapilli-block tuff with interspersed ash flows and lava flows and interbedded epiclastics comprise lithologies of the Attycelley Member. The Saunders Member consists of partially welded, crystal-rich dacitic ash flows (Bulletin 86). The primary unit underlying the Rich 1 showing is a flat lying quartz feldspar porphyry flow. This unit is in turn underlain by a grey, chlorite-epidote altered feldspar hornblende porphyry flow. Several andesitic dikes cut this porphyry. Both of these units are cut by a series of weak shear zones, striking 096 to 098 degrees and dipping vertical. Hostrock lithologies are intensely fractured and moderately to intensely silicified.

Numerous quartz-calcite veins up to 2.5 centimetres wide randomly cut the shear zones. These veins are weakly mineralized with malachite, pyrite and specularite. In 1983, rock sample GW-R-09 from one of these veins assayed 1.5 grams per tonne silver and 0.013 gram per tonne gold (Assessment Report 13083).

In 1983, on behalf of Golden Rule Resources Ltd., work carried out consisted of helicopter-supported geological mapping, prospecting, and geochemical sampling. A total of 93 stream sediment samples and 14 rock samples were collected during the program.
