Chalcopyrite-pyrite mineralization cut at a depth of 505 meters in hole CH-24-073 drilled this year at the BHP Zone on Pacific Ridge's Chuchi project.
Pacific Ridge Exploration Ltd. Nov. 27 reported that its 2024 drilling at Chuchi cut some of the highest copper and gold values ever encountered on the project roughly 35 kilometers (19 miles) northwest of Centerra Gold's Mount Milligan copper-gold mine.
The more than 16,000-hectare (39,500 acres) Chuchi property hosts several compelling exploration targets along a six-kilometer- (3.7 miles) long porphyry trend. This year's drilling tested BP Zone, a target along this trend that shows the potential to host significant porphyry copper-gold mineralization below shallow historical holes that ended in mineralization.
Highlights from historical holes drilled at BP Zone include:
• 194 meters averaging 0.21% copper and 0.21 grams per metric ton gold from a depth of 32 meters in hole CH-90-27.
• 250.5 meters averaging 0.21% copper and 0.12 g/t gold from a depth of 54 meters in hole CH-90-33.
• 207.8 meters averaging 0.22% copper and 0.12 g/t gold from a depth of 54.3 meters in hole CH-90-37.
Pacific Ridge's inaugural drill program at Chuchi consisted of 2,716 meters of drilling in five holes designed to confirm results from historical drilling at BP Zone and test an updated exploration model.
"Pacific Ridge's inaugural drill program at Chuchi was designed to test areas that historically returned the best copper and gold values," said Pacific Ridge President and CEO Blaine Monaghan.
Highlights from the 2024 drill program include:
• 413.9 meters averaging 0.15% copper and 0.15 g/t gold from a depth of 66 meters in hole CH-24-070, including 103 meters averaging 0.19% copper and 0.2 g/t gold.
• 382 meters averaging 0.19% copper and 0.12 g/t gold from a depth of 143 meters in hole CH-24-073, including 100 meters averaging 0.26% copper and 0.14 g/t gold.
• 298.2 meters averaging 0.21% copper and 0.11 g/t gold from a depth of 49.8 meters in hole CH-24-074, including 121 meters averaging 0.23% copper and 0.08 g/t gold.
The five holes were drilled along 750 meters of strike at BHP Zone.
"Not only did we return some of the highest copper and gold values ever recorded at Chuchi, and over longer runs, the results suggest that there is greater continuity of mineralization across the BP Zone than previously known," Monaghan. "The results also suggest that we are in the upper part of a large porphyry copper-gold system that has not been adequately tested and remains open laterally and to depth."
