Final Two Holes At The Superior Drill Program


TORONTO - US Copper Corp reported results from the final 2 drill holes of the 7 completed holes drilled in 2021 on its Superior deposit at the Moonlight-Superior Copper Project in North-East California. Results from all 7 holes met or exceeded expectations including: 1) Verifying 50-year-old historic drill results. 2) Silver and gold credits appear to increase Copper-equivalent grade by approximately 11% (8.2% - 14.4%). 3) Supporting the presence of higher-grade ore within the Superior deposit that can potentially be used to feed the Moonlight plant during early the production years to improve Project economics. These results from all 7 holes will now be reviewed by an independent engineering firm to determine: 1) A new resource calculation including silver and gold credits. 2) The economic impact of including Superior in our Moonlight mine plan.

Summary of drill hole data

US Copper had a Preliminary Economic Assessment (PEA) prepared on the Moonlight deposit in 2018 that showed positive economics. It was determined that providing higher grade ore from the Superior and/or Engels deposits into the Moonlight mine plan would substantially enhance the project's economics by increasing cash flows in the initial years of production. The recently completed drill program at Superior was designed specifically for that purpose. Ultimately, the updated Superior resource will be incorporated into a revised Moonlight PEA.

"We are quite pleased with the results of all 7 holes as they clearly demonstrate excellent continuity of grade, the presence of higher-grade ore within the Superior deposit, and the potential for including silver and gold credits," said, Stephen Dunn, President and CEO. "We look forward to a new study on the economic impact of including higher grade ore from Superior into the Moonlight mine plan in 2022 as well as the completion of the drill program at our Engels deposit."
