Status: MADE-IN-AMERICA COPPER

[ TSX: GCU // OTC: GCUMF ]

COPPER IS THE WIRING OF WAR.

Mission: Deliver a U.S. supply stream of finished copper cathode engineered for defense primes, hyperscale data centers, grid hardening, and industrial electrification.

Platform: A district scale copper producer in Cochise County, Arizona now producing copper cathode at the Johnson Camp Mine and a scaled development pathway at the flagship Gunnison Project (open-pit + heap leach + SX-EW) designed to keep cathode output under U.S. jurisdiction.

Procurement signal: predictable throughput depends on controlling the processing chain (leach + SX-EW) and the reagent and power cost stack.

Up to 25M lbs/yr Johnson Camp SX-EW Cathode Capacity (restarted / producing)

167M lbs/yr Gunnison Project PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the conclusions reached in the PEA will be realized

COPPER SIGNAL // WIRING OF WAR

current → comms → power → guidance

PRODUCTION STACK

JOHNSON CAMP MINE (JCM)

Now producing cathode output through heap leach + SX-EW.

The procurement advantage is simple: it converts material to finished cathode on U.S. soil.

Deliverable: Finished copper cathode (on-site refining)
System: Leach solution → solvent extraction → electrowinning
Supply-chain: Reduced reliance on offshore refining chokepoints

GUNNISON PROJECT (PEA)

Scaled open pit feeding heap leach pads and on-site SX-EW. Built to support volume delivery into electrification demand and critical infrastructure buildouts.

Cu: 832 Mtons @ 0.31% (M: 191.3 Mt @ 0.37% I: 640.2 Mt @0.29%) Open Pit M&I Resources. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

$1.42/lb C1 t0 Sustaining Cash Cost (LOM Avg) $1.94/lb. The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the conclusions reached in the PEA will be realized.

BYPRODUCT CREDITS

REAGENT + POWER OFFSETS

Heap-leach copper is reagent-intensive. The PEA case includes an on-site sulfuric acid plant with power co-generation credits, targeting operating stability when reagent supply chains tighten.

On-site acid: lowers dependence on external reagent supply
Co-gen credits: modeled offset to operating cost via energy value
Flex mode: PEA assumes buying acid if short, selling if excess.

~10.6 lbs acid / lb Cu PEA: life-of-mine average acid consumption intensity

$36/ton (modeled) PEA: on-site acid cost incl. power co-gen credits (assumption)

WHY PROCUREMENT CARES

For defense and hyperscale buyers, reliability under stress is the differentiator. Reagents, energy, and logistics are where disruptions start. This configuration emphasizes control of critical inputs to keep cathode production steady.

$130/ton (modeled) PEA: potential acid selling price (assumption)

$150/ton (modeled) PEA: acid buying price when needed above capacity (assumption)

OFFSET LOOP

ACID + POWER → COST STABILITY

Acid → Leach → Cathode → Power → Acid

Stable inputs = stable output.

NATIONAL DEFENSE RUNS ON COPPER.

Copper underpins defense electronics and the energy backbone powering modern systems: power distribution, secure communications, vehicles, radar, manufacturing lines, shipyard electrics, and the grid behind it all. A secure cathode stream reduces exposure to offshore refining constraints and geopolitical disruption.

Defense demand: wiring harnesses, motors, generators, power electronics, secure facilities
Tech demand: data center power trains, busbars, switchgear, grid interconnects
Security: U.S.-based cathode supports jurisdictional control and response readiness

NOTE TO U.S. INVESTORS:

For additional information on the Gunnison Project, including the PEA and mineral resource estimate, please refer to the Company's technical report entitled "Gunnison Project NI 43-101 Technical Report Preliminary Economic Assessment" dated effective November 1, 2024 and available on SEDAR+ at www.sedarplus.ca.

Dr. Stephen Twyerould, Fellow of AUSIMM, President and CEO of the Company is a Qualified Person as defined by NI 43-101. Dr. Twyerould has reviewed and is responsible for the technical information contained in this news release.

Certain statements contained in this release constitute forward-looking information within the meaning of applicable Canadian securities laws. Such forward-looking statements relate to the intention to deploy the Nuton® technology at the Johnson Camp mine and future production therefrom; the continued funding of the stage 2 work program by Nuton; the details and expected results of the stage two work program; future production and production capacity from the Company's mineral projects; the results of the preliminary economic assessment on the Gunnison Project; and the exploration and development of the Company's mineral projects.

In certain cases, forward-looking information can be identified by the use of words such as "plans", "expects" or "does not expect", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might", "occur" or "be achieved" suggesting future outcomes, or other expectations, beliefs, plans, objectives, assumptions, intentions or statements about future events or performance.
