Copper staining on a limestone outcrop south of Laverdiere, a target drilled this year on Core Assets' Blue property in the Atlin Mining District of Northern British Columbia.
Core Assets Corp. Aug. 8 reported that assays from the first two holes of the 2022 season returned strong copper and gold skarn intercepts, as well as a wider section of porphyry-style copper mineralization at the Laverdiere project on the company's Blue property in British Columbia's Golden Triangle.
Located in the gold-rich Atlin Mining District, Blue is a 111,649-hectare (275,890 acres) land package covering high-grade skarn and carbonate replacement and porphyry prospects enriched with silver, gold, copper, zinc, and lead.
Core's inaugural drill program at Blue began near the French Adit area of Laverdiere, a prospect area in the southern part of the property that hosts three areas of skarn exposure with massive and disseminated sulfide.
Historical drilling at Laverdiere cut 46 meters averaging 1.76% copper from surface; and 175 meters averaging 0.27% copper from surface.
Core Assets first hole, LAV22-001, cut 95.05 meters averaging 0.47% copper, 3.24 grams per metric ton silver, and 0.06 g/t gold from a depth of one meter, including 48.5 meters averaging 0.9% copper, 5.8 g/t silver, and 0.11 g/t gold, confirming the presence of high-grade copper and associated gold skarn.
From a depth of 163.5 meters, LAV22-001 also cut 1.51 meters averaging 4.59 g/t gold and 0.38 g/t silver, confirming the presence of high-grade gold hosted within the prolific Llewellyn Fault Zone (LFZ).
Further information on the Llewellyn Fault Zone can be found at Drilling tests Core Assets' Blue targets in the July 20, 2022 edition of North of 60 Mining News.
LAV22-002, the deepest hole drilled at Blue to date, cut 210.5 meters averaging 0.11% copper, 0.05 g/t gold, and 1.76 g/t silver from a depth of 15 meters, including two meters averaging 3.01% copper, 0.3 g/t gold, and 18.8 g/t silver from 104 meters.
"The goal of drilling in the French Adit area was to determine the depth extent of historic copper and gold skarn mineralization from surface and to test the porphyry Cu-Mo (copper-molybdenum) potential of the Laverdiere intrusion," said Core Assets President and CEO Nick Rodway. "These results have confirmed and over exceeded our expectations – especially when considering the shear-hosted gold hit within the LFZ."
Core says four additional holes drilled at Laverdiere cut similar high-temperature skarn and porphyry-style mineralization, veining, and alteration over a strike of 850 meters. Assays are pending.
"Drilling completed to-date has only begun to scratch the surface and indicates the presence of a potentially large porphyry system," Rodway added. "We look forward to receiving the remaining assay results at Laverdiere and planning a more aggressive diamond drilling program for 2023."
The 2022 diamond drilling campaign on the Blue property is now testing the Sulphide City target at Silver Lime, a carbonate replacement copper-zinc-silver prospect about 10 kilometers (six miles) east of Laverdiere.
An extensive first pass exploration program carried out by Core at Silver Lime in 2021 defined a 3,700- by 1,800-meter area of high-grade carbonate replacement and skarn mineralization within a broad 6.6-kilometer (4.1 miles) mineralized corridor that remains open.
Core plans to complete more than 5,000 meters of drilling at Blue this year.
