• US Copper has Commenced Discussions with Potential Strategic Partners to Advance its 100% Owned Moonlight-Superior Copper Project.

• US Copper's Moonlight - Superior Copper Project is a historically operating project with potential to restart and become a domestic supply of copper to the US market.

• Copper Prices broke $10,000/t (i.e. US$4.53/lb) in recent weeks as Copper undergoes an unprecedented structural change driven by global energy transition.

• The project's US location positions it as a preferred supplier to the US domestic industry and a candidate for possible US Government funding support.

Toronto, May 28, 2024 - US Copper Corp., (TSXV: USCU) (OTCQB: USCUF) (FSE: C730) ("US Copper" or the "Company") is pleased to announce that it has commenced discussions with strategic partners to facilitate the Company's ongoing efforts to advance its large, advanced Moonlight-Superior Project, a historically operated copper mine in California, back into production. Steve Dunn, CEO, noted:

"There is strong interest by strategic partners in Moonlight-Superior driven by the recent move of copper prices above US$10,000/t (US$4.53/lb) as well as the project's U.S. location which dovetails nicely with the push by the U.S. Government to stimulate new domestic sources of critical metals, including copper, via various incentive and financial support programs. With the recently announced drilling results, timing is ideal and we are excited to commence discussions with potential strategic partners to advance the project through Definitive Feasibility Study and development of the mine. We look forward to updating shareholders as discussions progress."

US Copper is developing the Moonlight-Superior Project, a historically operated copper mine in California, located approximately 125 miles from Tesla's Gigafactory outside Reno, Nevada. President Biden's Defense Act Order highlights the important role that the Company can play in ensuring the United States has a secure supply of one of the key metals to achieve its transition to a low carbon economy. Copper is a critical material for everything from renewable power generation to electric vehicles. As such, it will be vital that the U.S. has a strong and viable domestic source of copper supply.

US Copper is focused on advancing its Moonlight-Superior Project towards the production stage. The Company hopes to support the United States' shift to a green future by providing copper to the myriad of industries involved in the green energy transition.

CEO Steve Dunn further commented, "The Company is working hard to advance its project back into production and is excited about the opportunity to be an integral supplier of copper metal to the U.S. domestic market."

About US Copper Corp.

US Copper controls approximately 13 square miles of patented and unpatented federal mining claims in the Lights 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 2.2% copper with silver and gold credits.

The Moonlight Deposit was discovered and drilled by Placer-Amex during the 1960s. The Moonlight sulfide deposit hosts a current National Instrument 43-101 ("NI 43-101") indicated resource of approximately 252 million tons (154 million tonnes) averaging 0.25% copper and 0.07 oz/silver per ton, and an inferred resource of 109 million tons (62 million tonnes) averaging 0.24% copper and 0.08 oz/silver per ton, both above a US$6.25 net smelter return cut-off. Contained indicated resources are 1.272 billion pounds of copper and 18 million ounces of silver, and inferred resources of 534 million pounds of copper and 9 million ounces of silver. The Moonlight sulfide deposit remains open to the south and at depth. There are also current NI 43-101 resources at the Superior and Engels deposits. Details of the resources on US Copper's property and the parameters used to calculate them can be found in the "Technical Report and Preliminary Economic Assessment for the Moonlight Deposit, Moonlight-Superior Copper Project, California, USA" dated April 12, 2018 on both the company's website at www.uscoppercorp.com or on www.sedar.com under the US Copper Corp. profile.
