Gunnison Copper is ramping up drilling across our Southern Arizona copper district.

President & CEO Craig Hallworth and VP, Investor Relations & Communications Melissa Mackie recently joined Mining.com.au's Danielle Doporto to discuss the next phase of growth at Gunnison Copper.

Expanding to six rigs, our 2026 district-wide program is advancing multiple priorities:

🔹 Metallurgical testing to further optimize copper recoveries
🔹 Resource expansion and conversion at Gunnison and Strong & Harris
🔹 Up to 405 column leach tests planned
🔹 Drilling, metallurgy and engineering supporting the Prefeasibility Study
🔹 Continued ramp-up of copper production at Johnson Camp

As Craig explains, this work is about more than drilling - it’s about building the technical foundation to advance a large emerging copper development opportunity in the United States.

📈 Copper continues to strengthen.

Following yesterday's rally, COMEX copper extended its gains again today, trading just shy of the all-time high of US$6.71/lb.

For Gunnison Copper, higher copper prices have a significant impact on project economics.

Our 2026 Preliminary Economic Assessment uses a base case copper price of US$4.60/lb, which delivers:

🟠 After-tax NPV8: US$2.0 billion
🟠 After-tax IRR: 22.5%
🟠 Payback: 3.9 years

At a copper price of US$6.50/lb—close to where COMEX is trading today—the same study outlines:

🟠 After-tax NPV8: US$4.0 billion
🟠 After-tax IRR: 37.5%
🟠 Payback: 2.2 years
🟠 Life-of-mine EBITDA: US$20.4 billion
🟠 Unlevered after-tax free cash flow: US$14.4 billion

With copper prices approaching record highs, the value and cash flow potential of the Gunnison Project continue to grow.
