Atlin Gold Project Summary
The Atlin Gold Project consists of 55,474 hectares (555 SQKM) of 100% Brixton-owned claims over favourable geology near Atlin, BC. The property is road-accessible from Atlin, BC.
Brixton’s land package offers large target areas for exploration in search of Barkerville-style or California-style mother-lode gold deposits that may exist in prospective host rocks that are masked by overburden.
In 2016, coarse gold veins were discovered in graphitic phyllite of the Cache Creek Terrane in Otter Creek, beneath active placer workings, confirming a local source for the typically coarse placer gold.
Brixton Metals Corporation wholly owns the Atlin Gold Project.

2017 Atlin Gold Project Exploration Summary
Results from 26 rock samples returned a high of 24 g/t Au. Twelve of the 26 samples were greater that 0.1 g/t Au. The samples were collected in the vicinity of historic trenches on the LD claims; however, at the time of sampling the trenches were reclaimed and filled in. Brixton conducted an airborne magnetic survey of eight flight lines covering a total of 4,571 line kilometres of high resolution magnetic data. The traverse lines were flown East-West at a spacing of 200 metres with control lines flown North-South at a separation of 2000 metres. Nominal terrain clearance was specified at 100 metres above ground. Compilation of historic data and interpretation of the airborne magnetic survey is ongoing.
Map showing the LD Claims:
Historical work on the LD claims includes 330 g/t Au (mini-bulk sample), 1,615 g/t Au (rock grab sample) and 3m of 9.39 g/t Au (drill core). Brixton’s land package in the Atlin gold camp offers large target areas for exploration in search of Barkerville style or California style mother-lode gold deposits that may exist in prospective host rocks that are masked by overburden.
The Atlin gold camp is the second largest gold producer in British Columbia on record (Ash, 2001) with a reported placer gold production of over 600,000 ounces gold between 1898 and 1946 from creeks in the area. The Atlin gold camp (Spruce Creek) holds the provincial record for the largest nugget, weighing 2.6 kilograms (85 ounces – BCGS Paper 2017-1, p.179-193).
Historically, the primary exploration targets for lode gold have been quartz-carbonate-mariposite-altered (“listwanite”) ultramafic and mafic bedrocks. Quartz +/- carbonate gold-bearing veins and vein networks are structurally controlled and concentrated along shear zones, faults and deformed lithological contacts. British Columbia Geological Survey (BCGS) has recently released a paper (BCGS Paper 2017-1, p.179-193) in which the Government geologists recognize that at least some of the placer gold may be related to the Surprise Lake batholith. While over 600,000 ounces of gold was reportedly recovered from placer mining very limited exploration has been conducted in locating the hard rock source of the Atlin gold.
Several of the creeks crossing Brixton’s claims have seen historic placer production up to 44,109 oz Au on McKee Creek BC MEMPR Paper 1984-2. The most extensive hard rock exploration work to date on Brixton’s claims has been on the LD property, and includes soil sampling, geophysical surveys, trenching, chip sampling and bulk sampling. Highlights from the work on the LD property includes 330 g/t Au (bulk sample), 1615 g/t Au (rock sample) and 3m of 9.39 g/t Au (drill core). Soil sampling has been an effective exploration tool on the LD claims.
Brixton’s extensive land position covers both Surprise Lake batholith and favourable sedimentary rocks of the Cache Creek terrane. The Company’s plan is to conduct regional exploration work to generate drill targets within this early stage district scale gold play.
