US Copper Corp. announced 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: Verifying 50-year-old historic drill results. Silver and gold credits appear to increase Copper-equivalent grade by approximately 11% (8.2% - 14.4%). 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: A new resource calculation including silver and gold credits. The economic impact of including Superior in Moonlight mine plan. US Copper had a Preliminary Economic Assessment ("PEA") prepared on its Moonlight deposit in 2018 that showed positive economics at $3.15 copper. It was determined that providing higher grade ore from 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. US Copper personnel regularly observe procedures including the boxing of core at the drill site. Core is then securely delivered to the core logging and storage facility in Crescent Mills CA (10 miles from the drill sites). The core is logged, magnetically scanned, and photographed. Periodic samples are collected for specific gravity testing and petrographic analysis. The core is then sawn in half. One half is bagged with appropriate documentation and securely transported to the ALS lab in Reno, NV. To ensure that proper QAQC accompanies the analyses appropriate QAQC elements are included in each batch of samples. The QAQC elements consist of certified standards, duplicate analyses and certified coarse blanks or blank material that has been documented to be barren for gold and base metals.
