US Copper Corp. announced that drilling crews have arrived onsite to commence the 2023 exploration drill program at the Company's wholly-owned Moonlight-Superior Project, located in Plumas County, California. The Moonlight-Superior Project has a mineral resource estimate of 1.3 billion pounds of copper indicated and 1 billion pounds of copper inferred across three deposits - Moonlight, Superior and Engels.

The 2023 exploration drill program will focus on the Engels deposit and include 15 reverse circulation drill holes into the oxide cap that sits on top of the Engels sulfide deposit. Sample intercepts from prior drill programs at Engels reveal a high-grade copper oxide cap developed to depths greater than 230 feet ("ft") over an area of at least 1,000 ft by 500 ft. The main objectives of the 2023 drill program include: Upgrading and potentially expanding the current oxide resource estimate; Providing samples for preliminary metallurgical evaluation; and Providing initial data for inclusion in a preliminary economic assessment ("PEA") on the Engels oxide deposit.
