Updated Mineral Resource Estimate For Moonlight-Superior Project

TORONTO - US Copper Corp announced an updated Mineral Resource Estimate on the Moonlight-Superior Copper Project in Northeast California. 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 comprises an open-pit Indicated Resource of 402 million tons grading 0.31% Cu for total contained metal of 2.5 billion pounds of copper, representing a 99% increase in the Indicated Resource Category for contained copper from our 2018 Resource Estimate. This updated Resource also includes an additional Inferred Resource of 64 million tons grading 0.31% copper for total contained metal of 394 million pounds of copper.

Stephen Dunn, CEO, said, "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.

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."
