Two sections of core from hole THN24-291 drilled at the Camp Creek porphyry target at Thorn.
Brixton Metals Corp. Aug. 6 reported that the second hole of its 2024 drill campaign at the Thorn project in Northern British Columbia encountered 61.5 meters of gold-dominant mineralization before cutting through more than 1.1 kilometers of porphyry copper-gold-silver-molybdenum mineralization.
The first two holes of Brixton's 2024 program were drilled at Camp Creek, a large porphyry target in the northern half of the 2,863-square-kilometer (1,105 square miles) Thorn property.
While a resource has yet to be calculated for Camp Creek, drilling over the previous three seasons has outlined a large body of porphyry copper-gold-silver-molybdenum mineralization.
Highlights from previous seasons drilling at Camp Creek 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.
• 779.7 meters averaging 0.23% copper, 0.05 g/t gold, 2.46 g/t silver, and 234.7 ppm molybdenum in hole THN22-221.
• 1,562.4 meters averaging 0.19% copper, 0.05 g/t gold, 2.81 g/t silver, and 189 ppm molybdenum in hole THN23-261.
This year's drilling continues to cut similar long sections of porphyry mineralization.
Hole THN24-290, reported by Brixton in July, cut 960.4 meters averaging 0.21% copper, 0.06 g/t gold, 2.71 g/t silver, and 279 ppm molybdenum from a depth of 314.5 meters, including 452-meter subsection averaging 0.28% copper, 0.08 g/t gold, 3.39 g/t silver, and 272 ppm molybdenum.
Brixton says this expansion hole, which infills a gap in previous drilling, significantly increases the volume of porphyry mineralization at Camp Creek.
Hole THN24-291, which was drilled about 400 meters west of THN24-291, cut two mineralized zones, a gold-dominant upper zone and a thick porphyry zone.
At a depth of 116.5 meters, THN24-291 cut 61.5 meters averaging 0.89 g/t gold, 10.5 g/t silver, and 0.13% copper, including an 11-meter subsection averaging 3.53 g/t gold, 43.7 g/t silver, and 0.67% copper.
Brixton says this upper intercept appears to be part of the Talisker Zone high-sulfidation gold system, which has now been traced for 900 meters.
At a depth of 398 meters, THN24-291 cut 1,126 meters averaging 0.18% copper, 0.05 g/t gold, 1.82 g/t silver, and 167 ppm molybdenum, including a 575.5-meter subsection averaging 0.27% copper, 0.06 g/t gold, 2.232 g/t silver, and 266 ppm molybdenum.
This hole extends the body of porphyry mineralization being outlined at Camp Creek to the northwest.
"We are excited to announce that THN24-291 has expanded the known broad copper mineralization at the Camp Creek porphyry target and provided a 250-meter extension of the Talisker Gold Zone at the Thorn project," said Brixton Metals Vice President of Exploration Christina Anstey.
In addition to the drilling at Camp Creek, Brixton's 2024 drill program is testing several new porphyry copper-gold targets across the wider property.
Cirque, North Copper, and Trifecta are at the top of the list of porphyry targets across the wider Thorn property to be drilled this year.
"We look forward to receiving additional assays from the Camp Creek drilling and some of the new multi-kilometer scale regional untested drill targets being explored during this fully funded season," Anstey added.
The funding for this program comes from a C$14.5 million (US$10.6 million) financing in November that included participation by BHP Group, which holds a 19.9% interest in Brixton.
