Continues to outline large porphyry at Northern BC project North of 60 Mining News - December 13, 2023
Chalcopyrite, pyrite, and molybdenite mineralization encountered at a depth of 977 meters in THN23-285, a hole that cut 1,565 meters of porphyry copper mineralization.

Brixton Metals Corp. Dec. 13 announced that drills are continuing to cut nearly one-mile-thick zones of porphyry copper-gold-silver-molybdenum mineralization at the Camp Creek target on the company's Thorn project in Northern British Columbia.
Situated about 55 miles (90 kilometers) east of Juneau, Alaska, the 2,863-square-kilometer (1,105 square miles) Thorn project hosts both porphyry copper-gold-silver-molybdenum and high-grade epithermal gold targets.
Late last year, BHP Group Ltd. invested C$13.6 million (US$9.9 million) to acquire a 19.9% interest in Brixton. The global mining giant maintained its 19.9% stake through the purchase of 16.38 million shares during a C$14.5 million (US$10.7 million) Brixton financing that closed in November.
A technical team that included members from BHP and Brixton developed a 16,725-meter drill program for the Thorn project during 2023. This program included 10,100 meters of drilling in nine deep holes at Camp Creek.
Over the previous two years, Brixton had begun outlining a large copper mineralized body at Camp Creek. Highlights from the 2021 and 2022 drilling include:
• 976.5 meters averaging 0.22% copper, 0.07 grams per metric ton gold, 2.06 g/t silver, and 154.4 parts per million molybdenum in hole THN21-183.
• 821.3 meters averaging 0.24% copper, 0.1 g/t gold, 2.44 g/t silver, and 174.3 ppm molybdenum in hole THN21-184.
• 967.7 meters averaging 0.25% copper, 0.09 g/t gold, 2.39 g/t silver, and 186 ppm molybdenum in hole THN22-201.
• 709 meters averaging 0.24% copper, 0.06 g/t gold, 2.42 g/t silver, and 140.5 ppm molybdenum in hole THN22-213.
• 779.7 meters averaging 0.23% copper, 0.05 g/t gold, 2.46 g/t silver, and 234.7 ppm molybdenum in hole THN22-213.
In September, Brixton reported a nearly one-mile-long porphyry copper intercept at Camp Creek, the longest drilled there to date. This hole, THN23-261, cut 1,562.4 meters averaging 0.19% copper, 0.05 g/t gold, 2.81 g/t silver, and 189 ppm molybdenum. This intercept included an 855-meter subsection averaging 0.29% copper, 0.06 g/t gold, 2.44 g/t silver, and 314 ppm molybdenum.
The final batch of assays from four holes also included a hole that cut through nearly a mile of porphyry mineralization. From a depth of 37.5 meters, this hole cut 1,564.5 meters averaging 0.15% copper, 0.08 g/t gold, 2.09 g/t silver, and 246 ppm molybdenum. This intercept included a 717-meter subsection averaging 0.2% copper, 0.05 g/t gold, 1.92 g/t silver, and 458 ppm molybdenum.
THN23-285 was drilled 170 meters east of THN22-201 and 200 meters southeast of THN21-184 (assays from these holes are reported above).
"2023 proved to be another successful year on the Camp Creek Copper Porphyry Target. We have what appears to be a large mineralized and alteration footprint with limited deep holes testing a buried system," said Brixton Metals Chairman and CEO Gary Thompson.
In its ongoing search for other potential orebodies around Camp Creek, Brixton is collaborating with the University of British Columbia's Mineral Deposit Research Unit (MDRU) to establish geochemical and alteration vectors towards blind porphyry mineralization.
This work includes an alteration mapping project to characterize and map the large 4.1-by-3.9-kilometer (2.5 by 2.4 miles) alteration footprint centered around Camp Creek. With porphyry deposits frequently found in clusters, the team will analyze drill core and 177 hand specimens collected within the alteration footprint during 2023 to aid with further vectoring outside of the currently drilled area.
"In collaboration with MDRU (UBC's Mineral Deposit Research Unit) and the recent oversubscribed $14.5 million financing, we look forward to further drill-testing this target during the 2024 field season," Thompson added.
