US Copper Corp Completes Drill Program at Moonlight-Superior

Copper Project in California

TORONTO, CANADA, August 21, 2023 – US Copper Corp. (“US Copper” or the “Company”)

(TSX Venture: USCU) (OTCQB: USCUF) (Frankfurt: C730) is pleased to announce the

completion of the exploration drilling program announced on Jun e 8, 2023, at the Company’s

wholly-owned Moonlight-Superior Copper 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 resource estimate is contained in the National Inst rument 43-101 (“ NI 43-101 ”)

Technical Report and Resource Estimate for the Superior Project, Plumas County, California, with

an effective date of November 15, 2013, available on US Copper’ s website and on SEDAR+ at

www.sedarplus.ca.

A total of 15 shallow holes totalling 3,990 feet were drilled a t the Engels deposit to test the oxide

cap that sits atop the Engels copper sulfide deposit. Drilling at Engels proceeded quickly and the

Company was also able to drill an additional 15 holes at the Moonlight deposit totalling 2,430 feet

to test the oxide cap on that deposit. A further two holes wer e then drilled at the Lambs Ridge

historical copper deposit. Samples from all 32 holes have been logged, bagged and sent to the lab

for assays. Assay results are expected to be available in September.

The main objectives of the 2023 exploration drill program include:

1. Upgrading and potentially expanding the current oxide resource estimate;

2. Providing samples for preliminary metallurgical evaluation; and

3. Providing initial data for inclus ion in a preliminary economic assessment on the Engels

oxide deposit.

“As an exploration and development stage company with a copper project in northern California,

we welcome the recent decision by the U.S. Department of Energy to add copper to the critical

materials list. This decision was based on the high risk of U. S. copper supply disruption and its

importance to domestic manufacturers of electric vehicles and c lean energy technologies. With

global copper demand projected to double by 2035, the U.S. will need to develop a secure and

responsible domestic supply of m ined copper. We look forward t o working with our California

stakeholders and prospective part ners to advance the strategica lly important Moonlight-Superior

Copper Project.” commented Stephen Dunn, President and CEO of US Copper.

The Company would also like to announce that its Board has approved the grant of 4,625,000 stock

options to certain directors, o fficers and consultants of the C ompany, subject to regulatory and

TSX Venture Exchange approval. The stock options have been issu ed with an exercise price of

$0.10 per share, vest immediately, and have a 3-year term.

US Copper controls approximately 13 square miles of federal min ing claims in the Light’s Creek

Copper District in Plumas County, NE California; essentially, t he entire District. The District

contains substantial copper (silv er) sulfide and copper oxide r esources 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 1915-1930 pro ducing over 161 million

pounds of copper from over 4 MT of rock containing 2.2% copper with silver and gold credits.

The Moonlight Deposit was discovered and drilled by Placer Amex during the 1960s. Details of

the resources on US Copper’s property and the parameters used to calculate them can be found in
