The OLYMPIC (L.6280) (BILLYO ZONE) prospect is located east of Howe (Marquis) Creek on the south shore of Carpenter Lake, approximately 8.5 kilometres northeast of Gold Bridge, B.C.

The BillyO "massive sulphide" zone is hosted in Mississippian to Jurassic Bridge River Complex (Group) metasediments. Trenching exposes a garnet-diopside skarn in iron-oxidized vesicular felsite breccia containing lensoid pyrite, pyrrhotite, magnetite and chalcopyrite. An adit and nearby drill holes located pyrite and magnetite stringers but failed to reach massive sulphide mineralization. Over 30 centimetres, sulphides geochemically analysed 0.27 grams per tonne gold, 3.43 grams per tonne silver and 0.06 per cent copper and a grab sample ran 5.9 grams per tonne gold, 5.14 grams per tonne silver and 0.55 grams per tonne copper.

The Moly zone, on the west side of the BillyO zone, contains fracturing and quartz veining adjacent to or within a broad aplite dike surrounded by a pyrite/gypsum halo. Mineralization consists of pyrite, pyrrhotite (dendritic), manganese staining, ferro-molybdenum staining and arsenopyrite.

The Kelvin and Olympic areas saw initial development in the mid 1930s and again in the mid 1940s with underground drifting plus some drilling on the Kelvin prospect. In 1980, Noranda Mines Ltd. undertook geological mapping, soil geochemical sampling and magnetometer surveying in the area, in addition to drilling two holes in the Moly zone. A mapping, sampling and geological report on the Kelvin and Olympic prospects, including BillyO, was completed by B. Price in 1982 (Assessment Report 11139). Big I Developments Ltd. conducted programs of geological mapping, grid soil geochemical sampling in the area in 1985, as well as extending southward with prospecting up Girl Creek (south of the Kelvin prospect) and up Howe (Marquis) Creek south of the Olympic prospect.

Avino Mines and Resources Ltd. acquired the Minto property to the north of Carpenter Lake and the Olympic property south of the lake in 1987, and conducted programs of soil sampling, airborne VLF-EM and magnetometer survey, trenching and diamond drilling through to 2005 (Assessment Reports 16964, 17790, 18433, 27443, 28340).

In 2022 and 2023, Endurance Gold Corp. conducted prospecting and geochemical orientation and sampling surveys on their Olympic property and on the Sanchez property to the east, as part of their Reliance Gold project. These surveys established parallel northwest trending targets across the Kelvin, Minto-Olympic and Enigma-Dauntless areas (Assessment Report 41676).
