US Copper Announces Final TWO Holes from Superior Drill Program
US COPPER ANNOUNCES FINAL TWO HOLES FROM SUPERIOR
DRILL PROGRAM
TORONTO, CANADA, November 15, 2021 – US Copper Corp (“ US Copper ” or the
“Company”) (TSX Venture: USCU) (OTCQB: USCUF) (Frankfurt: C73) is pleased to announce
results from the final 2 drill holes of the 7 completed holes d rilled in 2021 on its Superior deposit
at the Moonlight-Superior Copper Project in North-East California.
Highlights:
Results from all 7 holes met or exceeded expectations including:
1. Verifying 50-year-old historic drill results.
2. Silver and gold credits appear to increase Copper-equivalent gr ade by approximately 11%
(8.2% – 14.4%).
3. Supporting the presence of higher-grade ore within the Superior deposit that can potentially
be used to feed the Moonlight plant during early the production years to improve Project
economics.
These results from all 7 holes will now be reviewed by an indep endent engineering firm to
determine:
1. A new resource calculation including silver and gold credits.
2. The economic impact of including Superior in our Moonlight mine plan.

US Copper had a Preliminary Economic Assessment (“ PEA”) prepared on its Moonlight deposit
in 2018 that showed positive economics at $3.15 copper. It was determined that providing higher
grade ore from our Superior and/ or Engels deposits into the Moo nlight mine plan would
substantially enhance the proj ect’s economics by increasing cas h f l o w s i n t h e i n i t i a l y e a r s o f
production. The recently completed drill program at Superior wa s designed specif ically for that
purpose.
Ultimately, the updated Superior resource will be incorporated into a revised Moonlight PEA.
“We are quite pleased with the results of all 7 holes as they clearly demonstrate excellent continuity
of grade, the presence of highe r-grade ore within the Superio r deposit, and the potential for
including silver and gold credits.” commented St ephen Dunn, US Copper’s President and CEO.
“We look forward to a new study on the econo mic impact of including higher grade ore from
Superior into the Moonlight mine plan in 2022 as well as the completion of the drill program at
our Engels deposit.”
The Superior copper deposit is comprised of 60 million tons containing 0.41% Cu (Tanaka, 2013,
see details in the Moonlight PEA referred to below) and is located about 9,000 feet SE of Moonlight
and 11,000 feet SW of Engels. All seven holes completed during this drill phase are located in the
northern portion of the deposit and were drilled entirely in the quartz monzonite of the mid-Jurassic
Lights Creek Stock. Mineralizat ion consists of high-grade chal copyrite with minor bornite and
other copper sulfides in tourmalin e-magnetite veins and veinlet s. Lower-grade disseminated
mineralization is widespread adjacent to and between the vein-v einlets. No significant oxide
copper occurs at Superior, and pyrite is minor.
Technical Information and Quality Control & Quality Assurance
US Copper personnel regularly obser ve procedures including the boxing of core at the drill site.
Core is then securely delivered to the core logging and storage facility in Crescent Mills CA (~10
miles from the drill sites). The core is logged, magnetically scanned, and photographed. Periodic
samples are collected for specific gravity testing and petrographic analysis. The core is then sawn
in half. One half is bagged with appropriate documentation and securely transported to the ALS
lab in Reno, NV. To ensure that proper QAQC accompanies the an alyses appropriate QAQC
elements are included in each batch of samples. The QAQC elements consist of certified standards,
duplicate analyses and certified coarse blanks or blank materia l that has been documented to be
barren for gold and base metals.

About US Copper Corp
US Copper controls approximately 13 square miles of patented an d 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) su lfide and copper oxide resources in
three deposits – Moonlight, Superior and Engels, as well as sev eral 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 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 1960’s. Details of
the resources on US Copper’s property and the parameters used to calculate them can be found in
the “Technical Report and Preli minary Economic Assessment for t he Moonlight Deposit,
Moonlight-Superior Copper Project, California, USA” dated April 12, 2018, on both the
