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 293 g/t Au at the LD Showing (2017) and 53.6 g/t Au at the Union Mountain Showing (2020, Golden View Occurrence). Historical diamond drilling at the Yellowjacket Property has returned up to 509.96 g/t Au (or 16.39 oz/ton Au) over 5.57 metres.

 

In 2009, Eagle Plains Resources Ltd. and Prize Mining Corp. completed a resource estimate for the Yellowjacket Mine, located near Pine Creek on the Atlin Property. The Inferred Resource Estimate was 133,000 tonnes @ 5.8 g/t Au, totaling 24,000oz Au at a 1.5 g/t Au cut-off (Price, B.J. and Dandy, L., 2009; Technical Report on the Yellowjacket Gold Project; 43-101 Report). The 2009 Yellowjacket Inferred resource estimate was done for a previous operator according to NI 43-101 standards. A QP for Brixton Metals has not done sufficient work to classify the historical estimate as a current mineral resource and the Company is not treating the historical estimate as a current mineral resource.

Geology

The Atlin Goldfields property is underlain primarily by Mississippian to Triassic-aged volcanic and sedimentary rocks of the Cache Creek Complex, including quartz-carbonate-mariposite-altered ultramafic and mafic rocks (‘listwanite’), which are commonly associated with the gold mineralization in the region. The Cache Creek Complex is intruded by the Middle Jurassic Fourth of July batholith and the Late Cretaceous Surprise Lake batholith.

 

Placer mining from the Atlin creeks produces mostly sharp-edge, “hackly” gold nuggets, indicating proximity to a mineralized source. Recent studies have shown that mafic and ultramafic rocks are not the only source of Atlin’s placer gold. Sedimentary rocks of the Cache Creek Complex (specifically graphitic and quartz-rich phyllitic bedrock) are now known to host gold-bearing quartz veins in the region (Mihalynuk et al. 2017). Furthermore, detailed geochemical research on select Atlin gold nuggets has found tin (Sn)- and thorium (Th)-rich mineral intergrowths (cassiterite and thorite), likely derived from the Sn-U-Th-Mo-W-F rich Surprise Lake batholith (Mihalynuk et al. 2017). The implication of this work is that there are both Orogenic gold and Intrusion-Related gold systems to be targeted on the Atlin property.Click the link to the full BCGS report:A new lode gold discovery at Otter Creek: Another source for the Atlin placers

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 Au between 1898 and 1945 from creeks in the area. Atlin continues to produce gold to this day, although yields have not been reported since 1946. The area was discovered in 1896 and has produced gold for 125 years. 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).

 

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, covering over 900 km2.
