Copper mineralization tapped in BRDDH19-004, a 2019 hole drilled at Newmont Lake.
Crystal Lake Mining Corp. is finding plentiful copper, gold and silver mineralization emerging from the rapidly retreating glaciers on its Newmont Lake project in British Columbia's Golden Triangle.
Situated about 30 kilometers (19 miles) northwest of Skeena Resources' Eskay Creek project and about the same distance southeast of Teck Resources and Newmont Goldcorp's Galore Creek project, Newmont Lake is in an area renowned for world-class deposits rich in copper and gold.
NW Zone, which is related to the northeast trending McLymont fault on the Newmont Lake property, hosts 1.4 million metric tons of historical inferred resource containing 6.79 million pounds of copper, 200,000 oz gold and 291,000 oz silver.
Glacial melt over the 12 years since that resource was calculated, however, is showing that NW Zone is only a small part of a much larger mineralizing system covered by snow and ice.
This year, Crystal Lake focused on exploring areas of unprecedented glacial retreat north of NW Zone.
With the mineral exploration expertise of HEG & Associates Exploration Services, this program included soil and rock sampling; assaying of unsampled historical core; an induced polarization (IP) geophysical survey; 4,000 meters of core drilling; mapping; and construction of a camp and at Newmont Lake.
Crystal Lake said this work has delineated major porphyry copper-gold-silver discoveries along the Burgundy Ridge trend; new high-grade gold targets near the historical NW Zone resource; and new targets along the Newmont Lake Gold Corridor, which extends for more than 10 kilometers (six miles).
The company said the 2019 surface exploration at Burgundy Ridge is beginning to outline a porphyry copper-gold-silver trend that extends for 2,300 meters.
Crystal Lake encountered this mineralization with reverse circulation drilling completed late in 2018. The last hole of this program cut 58 meters of 0.31 percent copper and 0.27 g/t gold, followed by 1.5 meters of 2.6 percent copper.
While assays from the 2019 program are pending at the time of this report, the copper-gold-silver mineralization first is visually evident in the core.
Crystal Lake said preliminary interpretations of the 2019 surface exploration and drilling indicate the presence of a large high-grade skarn body adjacent to a porphyry system.
"The vastness of copper with associated gold and silver mineralization of multiple styles starting at surface is really impressive," said HEG President and CEO Cole Evans. "Our team has been tracking ice and snow retreat with a variety of tools. As it retreats, we are consistently being rewarded with new exposures of high-grade mineralization on surface. The first ever look at the subsurface from 2019 diamond drilling is giving us the confidence to make aggressive step outs with mineralization open along trend and at depth."
EDITOR'S NOTE: Drilling at Newmont Lake recently discovered a new porphyry copper-gold zone; and surface sampling has discovered high-grade gold , silver, copper, nickel, cobalt, zinc and lead mineralization along a separate corridor on the property. Further details can be found at Major metal trends at Newmont Lake in the Oct. 25 edition of North of 60 Mining News.
