The CARTER occurrence is located east of Steep Creek, approximately 2 kilometres southeast of Carpenter Lake and 4 kilometres northeast of Gold Bridge, B.C.

The area is underlain by Mississippian to Jurassic Bridge River Complex (Group) siliceous cherty sediments, argillites, limestones and volcanics. This package is intruded by granodiorite plugs of the Cretaceous to Tertiary Bendor pluton and also contains masses of serpentinite. Porphyritic dikes, probably Tertiary, also cut these rocks.

Locally, fine-grained massive volcanics (basalt) and cherty argillites host a shear zone with abundant quartz carbonate alteration and precious metal values. In 2004, grab samples assayed up to 4.81 grams per tonne gold and greater than 100 grams per tonne silver (Assessment Report 27700).

The area has been historically explored in conjunction with the Norma (MINFILE 092JNE134) occurrence to the southwest and the Senator (MINFILE 092JNE136) prospect to the northwest. In 2004, the area was prospected as the Bridge claim by Standard Corporation. In 2005 and 2006, Menika Mining Limited conducted MMI soil geochemistry surveys in the area. In 2008, diamond drilling on the Carter zone target area, located on the north side of Steep Creek, intercepted Pioneer volcanic and Cadwallader metasediments hosting sulphidic (pyrite and pyrrhotite) shear and tension quartz-carbonate veins associated with a quartz porphyry dike swarm. The best intercept from diamond drilling (hole UR08-0003) yielded 1.34 grams per tonne gold over 1.0 metre (Assessment Report 30524).

From 2020 through 2023, Endurance Gold Corp. conducted exploration programs on its Reliance GOLD project (MINFILE 092JNE033), including airborne and ground magnetic surveys, an airborne LiDAR survey, a ground 3DIP survey, geological mapping, alteration mapping, talus fine/soil sampling, biogeochemical sampling, rock grab and channel sampling, and reverse circulation (84 holes) and diamond drilling (82 holes). Drill holes were primarily in the Steep Creek area north of the Carter (Upper Reliance) showing, along the Royal Shear Fault. Diamond drilling was again focused along this fault in 2024, with 26 holes completed totaling 7,303 metres (https://endurancegold.com).
