Atlin Goldfields Project Summary

Brixton’s wholly owned Atlin Goldfields Project covers approximately 950 square kilometers of favourable and structurally intricate geology within the Atlin Mining District of NW, BC. The property is road accessible, located just 9 kilometers east of the community of Atlin, BC.

The Atlin Goldfield Project consists of multiple, large exploration targets that continue to show immense potential for uncovering Barkerville- or California-style mother-lode gold sources responsible for the numerous placer gold deposits present within the local mining camp; as well as the source of intrusion-related gold mineralization associated with a strong tin, tungsten, bismuth, and tellurium geochemical signature.

Rock samples consisting of coarse-grained quartz veins hosted in listwanite have returned values of up to 293g/t Au at the LD Showing (2017) and 53.6g/t Au at the Union Mountain Showing (2020, Golden View Occurrence). Historical diamond drilling at the Yellowjacket Property has returned up to 509.96g/t Au (or 16.39 oz/ton Au) over 5.57 meters.

Homestake Mineral Development Company (“Homestake”) discovered the Yellowjacket Gold Zone during the completion of 58 exploratory diamond drill holes in 1988, where gold mineralization was intercepted to depths of up to 140 meters. Homestake delineated a historical non-compliant resource estimate of 453,500 tonnes grading 10.26 g/t gold (British Columbia Department of Mines Open File 2000-2 page 41). These are historical figures and do not comply with the CIM reporting standards National Instrument 43-101 for mineral resources or reserves and should not be relied upon. While Brixton considers these historical estimates to be relevant to investors as it may indicate the presence of mineralization, a QP for Brixton has not done sufficient work to classify the historical estimates and Brixton is not treating these historical estimates as a current mineral resource.

Geology

Several creeks within Brixton’s claim block have seen historic placer production, with production records of 44,109 oz Au on McKee Creek (BC MEMPR Paper 1984-2). Historically, the most extensive hard rock (non-placer) exploration work to date on Brixton’s claims was on the Yellowjacket zone via drilling. Historical work at the LD showing includes soil sampling, geophysical surveys, trenching, chip sampling and bulk sampling. Highlights from the work on the LD property includes 330 g/t Au (15kg bulk sample), 1615 g/t Au (rock sample) and 3 meters of 9.39 g/t Au from core drilling. Soil sampling has been an effective exploration tool on areas of higher elevations to define drill targets.

Brixton’s extensive land tenure covers both the Surprise Lake batholith and favourable sedimentary rocks of the Cache Creek terrane.

In 2019, the Company is conducting a property scale exploration program to generate additional drill targets. The program includes airborne geophysical, soil-rock geochemical surveys, geological mapping, prospecting and the drilling of many short core holes.

History

The Atlin gold camp is the second largest gold producer in British Columbia (Ash, 2001) with reported placer gold production of over 600,000 oz of gold between 1898 and 1946 from creeks in the area; however, while gold production is still active today, yields have not been reported since 1946. The Atlin Goldfields Camp holds the provincial record for the largest gold nugget, which weighed 2.6 kg or 85 oz, and was discovered on Spruce Creek (BCGS Paper 2017-1, p.179-193).

Historically, the primary hard rock exploration targets for lode gold style mineralization have been quartz-carbonate-mariposite altered ultramafic and mafic bedrocks, commonly referred to as listwanite. Quartz-carbonate, gold-bearing veins and vein networks are structurally controlled and concentrated along shear zones, faults, and deformed lithological contacts. The British Columbia Geological Survey 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 significant tonnage has been recovered historically from placer mining, very limited exploration work in the camp has been conducted on discovering the hard rock source of the Atlin gold. Brixton’s claims are strategically located in this highly prospective mining camp.
