Mineral Resource Estimate for Moonlight-Superior Project
The Mineral Resource estimate for the Moonlight-Superior Project was prepared by Global Resource Engineering Ltd with an effective date of December 16, 2024. The Mineral Resource estimate incorporates geologic interpretations and a database compiled from historic drilling campaignsas well as recent drilling by US Copper. The resource database comprises 566 drill holes spanning 255,000 linear feet.

| Inferred | 64,000 | 0.31 | 0.005 | 0.77 | 267 | 9 | 1,400 |
Notes to table:
1. Mineral Resources are estimated using CIM Best Practices guidelines and 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves.
2. The Qualified Person for the Mineral Resources is Terre Lane, Principal Mining Engineer, Global Resource Engineering Ltd.
3. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
4. Rounding as required by reporting guidelines may result in apparent differences between tons, grade and contained metal content.
5. Mineral Resources are reported at a 0.16% Cu cutoff for oxide and transition material, and at a $10.45 net smelter return (NSR) cut-off for sulfide material. The oxide and transition cutoff is calculated based on a long term copper price of US$4.00/lb, assumed combined operating costs of US$7.50/ton, metallurgical recovery of 75% for copper. The sulfide cutoff is calculated as the breakeven NSR which is equal to the combined process and G&A costs for the sulfide material.
