Indicates drills are nearing core of porphyry system at Thorn North of 60 Mining News – October 22, 2021
Brixton Metals Corp. Oct. 19 reported a wide section of porphyry copper-gold-silver-molybdenum mineralization from drilling at the Camp Creek target on its Thorn project in British Columbia's Golden Triangle.
Located about 95 kilometers (60 miles) east of Juneau, Alaska, the 2,600-square-kilometer (1,004 square miles) Thorn property hosts large-scale porphyry copper-gold-silver-molybdenum and volcanic-sediment hosted gold-silver targets.
The latest batch of assay results is from drilling Camp Creek, a large porphyry target that remains largely underexplored.
A 2019 hole at Camp Creek, THN19-150, cut 554 meters averaging 0.57 grams per metric ton gold, 0.24% copper, and 43.18 g/t silver.
Another hole drilled during 2020 and then extended this year due to strong mineralization at the bottom of the hole, THN21-181A, cut 638.1 meters of porphyry mineralization averaging 0.18% copper, 0.07 g/t gold, 2.28 g/t silver, and 125.6 parts per million molybdenum.
Brixton says two holes drilled this year, THN21-183 and 184, are the first completed at Camp Creek where chalcopyrite is more abundant than pyrite, indicating the drilling is closing in on the core of the porphyry system.
Hole THN21-183, reported by the company in August, cut 976.5 meters averaging 0.22% copper, 0.07 g/t gold, 2.06 g/t silver, and 154.4 ppm molybdenum.
The latest assay results are from THN21-184, which was drilled about 250 meters east of THN21-181A and THN21-183.
Hole THN21-184 cut 821.3 meters averaging 0.24% copper, 0.1 g/t gold, 2.44 g/t silver, and 174.3 ppm molybdenum. A 1.85-meter interval near the bottom of this hole returned 89.3 g/t gold, which was cut to 10 g/t gold.
"Drill hole THN21-184 is an exciting follow up to THN21-183, with more encouraging copper grades. The 89.3 g/t gold interval found at depth in this hole is an exciting new development, as these gold grades are atypical of porphyry deposits," said Brixton Metals Vice President of Exploration Christina Anstey. "For our next drilling campaign, we plan to drill deeper step-outs with the goal of intercepting the enriched core of the Camp Creek porphyry."
In addition to these holes drilled at Camp Creek, Brixton completed 3,107 meters of drilling at Trapper, a volcanic-hosted epithermal gold-silver target about five miles (eight kilometers) to the southeast.
Assay results from the 15 holes drilled at Trapper are expected by mid-November.
