Up to 3.24% Copper Demonstrated Near the Anomaly
The drill-ready and easily accessible Laverdiere Copper Project of Core Assets Corp. (CSE:CC; FSE:5RJ; OTC.QB:CCOOF) is part of the vast Blue property and encompasses a 5 x 8 kilometer, little-explored copper porphyry area in northwest British Columbia. There, the company has identified mineralization in the newly defined Valley Zone around an impressive, donut-shaped geophysical anomaly measuring approximately 1 x 1.2 kilometers, which is interpreted as a likely high-grade porphyry center!
As Core Assets explains, the Valley Zone represents a highly prospective area with increased hydrothermal activity and high-grade porphyry copper mineralization, located 2 km southwest and 700 m higher than the Main Zone, which was tested by drilling in 2022. Both high-grade zones remain open for expansion in multiple directions.
Core Assets has now mapped and sampled multiple layered mineralized porphyry veins and fractures in altered granodiorite over a 1-kilometer east-west trend in the Valley Zone. The company, led by CEO Nick Rodway, had already demonstrated up to 3.24% copper (with 82 g/t silver, 0.56 g/t gold and 0.053% molybdenum) as well as 0.32% molybdenum (with 1.03% Cu, 4 g/t Ag) in 2022. With the exploration activities carried out last year, they then encountered 0.83% copper, 47 g/t silver, 0.44 g/t gold and 0.007% molybdenum.
The veins in the Valley Zone, which host significant copper, molybdenum, silver, and gold mineralization up to 20 centimeters thick, are also concentrated in an area of increased structural complexity. And this area coincides with the edges of a 1-kilometer wide and circular (donut-shaped) weakly magnetic geophysical anomaly that extends across multiple datasets.
Interestingly: Mineralized porphyry veins that Core Assets sampled at the surface and in drill cores from 2022 show a general increase in metal content towards the anomaly, which the company interprets as the location of a high-grade porphyry center!
Successful Drilling Already in 2022
In 2022, drilling conducted by Core Assets confirmed high-grade copper skarn and porphyry mineralization over a length of more than 1 kilometer, following the north-south trend of the Llewellyn Fault along the eastern edge of the Laverdiere Porphyry. Key drill intersections achieved in 2022 in the Main Zone include:
LAV22-006 (North Adit) – 107.38m at 0.11% copper (Cu), 0.023% molybdenum (Mo), 0.9g/t silver (Ag), 0.02g/t gold (Au) from 144.62m.
LAV22-001 (French Adit) – 267.05m at 0.17% Cu, 1 g/t Ag, 0.04 g/t Au from surface, including 48.54m at 0.90% Cu, 6 g/t Ag, 0.11 g/t Au from 31.46m depth.
LAV22-002 (French Adit) – 223m at 0.11% Cu, 0.006% Mo, 2 g/t Ag, 0.05 g/t Au from 15m depth, including 54m at 0.19% Cu, 0.002% Mo, 3 g/t Ag, 0.12 g/t Au from 173m depth, and 24.42m at 0.32% Cu, 0.005% Mo, 4 g/t Ag, 0.12 g/t Au from 207.23m depth.
LAV22-005 (South Adit) – 83.22m at 0.12% Cu, 0.016% Mo, 0.8g/t Ag, 0.03g/t Au from 6.9m depth.
LAV22-002 – the deepest hole drilled to date – intersected porphyry copper-molybdenum mineralization in the Main Zone to a true depth of up to 350 meters. Given the 700m elevation difference between the Valley and Main zones, Core Assets states there is a high probability that drilling in the Valley Zone could intersect copper-gold porphyry mineralization over 1 km.
Additionally, the company reports that historical adits driven into the massive and high-grade copper skarn of the Main Zone in the early 1900s demonstrated up to 1.20% copper over 27m, and historical drilling results yielded 175m at 0.24% copper, obtained in 1974, 100m north of the French Adit.
Potential also for gold mineralization contained in shear zones
According to Core Assets, the project is also considered highly prospective for shear-hosted gold mineralization. The first drill hole completed on the Laverdiere project in 2022 (LAV22-001) was drilled steeply to the east to test the LFZ and intersected quartz-carbonate-pyrite veins in deformed mafic volcanic rock, which yielded 4.59 g/t gold over 1.51 m at a depth of 163.49 m. The Llewellyn Fault Zone (LFZ) is believed to be spatially associated with gold mineralization along its entire length (>100 km).
Overall, the potential for Core Assets seems enormous, as the Blue property contains three (!) copper-, molybdenum-, and silver-bearing porphyries and associated high-grade massive sulfide skarn occurrences, indicating hydrothermal activity at least 50 million years old that extends over a 30-kilometer trend (!). Actually a unique opportunity in an emerging mining district for strategic investors…
