Copper Mountain Announces Positive Drilling Testing Depth Extensions at New Ingerbelle

VANCOUVER, BC, Sept. 8, 2020

VANCOUVER, BC, Sept. 8, 2020 /CNW/ - Copper Mountain Mining Corporation (TSX: CMMC | ASX:C6C) (the "Company" or "Copper Mountain") is pleased to announce positive results from two drill holes, totalling 1,538 metres that were drilled to test the depth extent of the New Ingerbelle copper-gold pit at the Copper Mountain mine. The Copper Mountain mine is located in southern British Columbia near the town of Princeton.

Highlights:

Hole 20IG-01 returned 585 metres of 0.51% CuEq (0.33% Cu, 0.21 g/t Au, 0.45 g/t Ag), including 213 metres of 0.75% CuEq (0.50% Cu, 0.29 g/t Au, 0.63 g/t Ag)
Hole 20IG-02 returned 120 metres of 1.02% CuEq (0.69% Cu, 0.37 g/t Au, 1.55 g/t Ag)

"These results indicate the immense potential that is inherent in New Ingerbelle," commented Gil Clausen, Copper Mountain's President and CEO. "The drill program shows that mineralization extends for at least an additional 250 metres below the design pit. Both holes terminated in ore, so we have not cut off the mineralization in any form. We are no where near understanding the extent of mineralization at New Ingerbelle. As a result of this drilling, we believe there is considerable potential to materially increase the mineral resource and ultimately the mineral reserve."

Mr. Clausen added, "Further, the average copper and gold grades of these wide intercepts are above the average mineral reserve grade at New Ingerbelle. New Ingerbelle has meaningful precious metals exposure with nearly 40% of its reserve value comprised of gold and silver. We plan to continue to invest in drilling at New Ingerbelle as the deposit is completely open."

Drilling was designed to test mineralization continuity at depth in the central part of the deposit area. Geology, alteration intensity and copper to gold ratios are consistent over the entire known vertical extent of mineralization. These positive drill results will be incorporated into the Company's annual mineral reserve and mineral resource update in the fourth quarter of 2020. Please see appendix for Drill Hole Location Map and Long Section. Significant drill results from the two completed drill holes are summarized in the table below.

¹CuEq calculated from NSR values when using metal prices (in US$) of 3.00, 1970.00, 28.00 and recoveries of 85%, 71%, 65% for Cu, Au, and Ag, respectively.

The two drill holes were drilled in scissor fashion, roughly east-west, on sections spaced 200 metres apart in the north-south direction. As sulphide bearing fractures have a strong vertical orientation, angle drilling provides a better representation of grade distribution. Mineralization in the New Ingerbelle deposit is hosted in both volcanic and intrusive rocks with grade distribution related to fracture patterns and host rock chemistry.

The New Ingerbelle deposit has reserves of 193 million tonnes grading 0.24% Cu, 0.15 g/t Au and 0.48 g/t Ag containing 1.0 billion pounds of copper, 929,000 ounces of gold and 3.0 million ounces of silver as at January 1, 2020 (as published in Copper Mountain's 2020 AIF). New Ingerbelle is situated one kilometre west of the Copper Mountain Main Pit.
