The Mac 2 occurrence is located at an elevation of approximately 1600 metres on a north-northeast–trending ridge, approximately 2.8 kilometres north-northwest of Mount McNamara.

The area is underlain by marine sedimentary rocks and volcanic rocks of the Upper Triassic Stuhini Group. These have been intruded by the Lower Jurassic Black Lake intrusive suite, which consists of generally medium-grained granodiorite to quartz monzonite.

Locally, a propylitic-altered granodiorite hosts quartz veins with chalcopyrite and galena.

In 2004, a grab sample (185133) of vein material assayed 0.331 per cent copper, 0.355 per cent lead, 0.468 per cent zinc, 31.3 grams per tonne silver and 0.945 gram per tonne gold (Assessment Report 27633).

Also at this time, a sample (185122) of hornfels subcrop hosting quartz-pyrite-chalcopyrite-magnetite, located approximately 1.3 kilometres to the south-southwest, yielded 14.7 grams per tonne silver, 4.74 grams per tonne gold and greater than 1.00 per cent copper (Assessment Report 27633).

Work History

In 1986, Toodoggone Gold Inc. completed a 278 line-kilometre airborne electromagnetic and magnetic survey on the area as the Fisher 1-2 and Wolverine 1-2 claims.

During 2004 through 2006, Stealth Minerals Limited completed exploration programs of soil and rock geochemical sampling, prospecting and geological mapping on the Mac 1-9 claims as a part of its Toodoggone project.

In 2017, Sable Resources Ltd. completed a helicopter-borne geophysical survey over the Bot property which included radiometric, magnetic, and ZTEM data. In 2018, Talisker Resources Ltd. conducted prospecting of geophysical anomalies (identified in the 2017 survey) located on the northern half of the Bot property. A total of 148 rock, silt and talus samples were collected and submitted for assay.
