Toronto, Ontario--(Newsfile Corp. - November 25, 2024) - US Copper Corp (TSXV: USCU) (OTCQB: USCUF) (FSE: C730) ("US Copper" or the "Company") is pleased to announce an updated Mineral Resource Estimate ("Resource") on its entire
This Resource will be used for the development of an updated Preliminary Economic Assessment ("PEA") on the Moonlight-Superior Project which is now anticipated in early January, 2025.
The updated Resource (see Table 1 below) comprises an open-pit Indicated Resource of 402 million tons grading
Management Commentary
Stephen Dunn, CEO of US Copper, commented: "We are extremely pleased with the results of the updated Mineral Resource Estimate ("MRE") for the Moonlight-Superior project. The overall copper resource now exceeds 2.5 billion pounds in the Indicated category, and our Moonlight-Superior Project is showing excellent potential to become a key American copper producer."
Mr. Dunn continued: "This MRE will provide the basis for a Preliminary Economic Assessment, which we expect will be available to release in early January 2025. As the world is facing growing supply/demand imbalance of this critical mineral, we strongly believe that this important asset could become a core component of the United States' critical mineral development strategy that aims to provide essential metals for the energy transition and ongoing demand growth from many economic sectors."
New Mineral Resource Estimate
The Resource Estimate is summarized in Table 1 below. The Resource Estimate was prepared by Terre Lane, of Global Resource Engineering, Denver, Colorado ("GRE"). Ms. Lane is independent of US Copper Corp. A technical report prepared in accordance with NI43-101 (the "Technical Report") will be filed on the Company's website and SEDAR+ within 45 days of the date of this press release.
Key assumptions reflected in the MRE are detailed below for each deposit and will be further described in the Technical Report.
This estimate is supported by more than 200,000 feet of historic drilling on the Project, conducted by Placer Amex, US Copper, and 3 other junior exploration companies, as well as a resampling and database validation program undertaken by the Company.

*Notes:
- The effective date of the Mineral Resource is September 15, 2024.
- The Qualified Person for the Mineral Resource Estimate is Terre Lane of GRE.
- Mineral resources are reported at a
0.16% Cu cutoff for oxide and transition material and at a 10.45 NSR/ton cutoff 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 (process and G&A); metallurgical recovery of75% 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. - Mineral resources are captured within an optimized pit shell and meet the test of reasonable prospects for economic extraction by open pit. The optimization used mining costs of US
$2.35 /ton mined and a 45º pit slope. - Rounding may result in apparent differences when summing tons, grade, and contained metal content.

About US Copper Corp
US Copper controls approximately 10 square miles of patented and unpatented federal mining claims in the Light's Creek Copper District in Plumas County, NE California; essentially, the entire District. The District contains substantial copper (silver) sulfide and copper oxide resources in three deposits - Moonlight, Superior and Engels, as well as several partially tested and untested exploration targets.
The Superior and Engels Mines operated from about 1915 to 1930 producing over 161 million pounds of copper from over 4 million tons of rock containing
The Moonlight deposit was discovered by Placer Amex during the 1960s and a resource was calculated after the drilling of over 400 holes. A development decision was made but then put on hold in 1972 when copper prices were weak. US Copper has owned the project since 2013 and has advanced the project with 3 different drill programs and a number of engineering studies. Further details can be found on both the Company's website at www.uscoppercorp.com and SEDAR+ at sedarplus.ca under the US Copper Corp profile.
