Gunnison Copper Advancing Gunnison Copper Project, Arizona

Why It Matters

The drilling results will underpin a pre‑feasibility study that could unlock a multi‑billion‑dollar copper mine, bolstering domestic production and reducing U.S. reliance on imported copper.

Key Takeaways

• 120 drill holes, 138,000 ft planned for Gunnison district.
• $15 M drilling budget, results due within 6‑15 months.
• Metallurgical phase targets 36 holes, 33,000 ft for column leach tests.
• Resource phase aims to upgrade inferred resources to measured/indicated.
• PEA shows $2 billion NPV, 23% IRR, 3.9‑year payback.

Pulse Analysis

Domestic copper demand is accelerating as the United States pushes for greater energy‑transition infrastructure, yet most supply still comes from abroad. Gunnison Copper’s Arizona project sits in the Southern Copper Belt, a region rich in porphyry deposits that could serve as a strategic source of primary copper. By expanding its district‑scale land package and committing to a comprehensive drilling program, the company is positioning itself to capture a larger share of this emerging market while aligning with U.S. policy goals for mineral security.

The newly funded drilling campaign is split into two distinct phases. An initial metallurgical drilling effort will collect 36 core samples across the Gunnison and Strong & Harris deposits, feeding up to 270 column leach tests—industry‑standard experiments that model heap‑leach performance. This data will refine ore‑processing assumptions and help optimize the planned heap‑leach and SX/EW plant. Following metallurgical work, a larger resource‑expansion phase will drill up to 84 additional holes, targeting extensions of known mineralization and converting inferred resources into measured and indicated categories. The $15 million spend, excluding payroll, reflects a focused investment aimed at de‑risking the project before a full PFS.

If the drilling validates the resource upgrades and metallurgical models, the upcoming pre‑feasibility study could confirm the $2 billion net present value and 23% internal rate of return highlighted in the March 2026 PEA. Such economics would attract both equity and debt investors seeking exposure to copper’s upside, while providing a domestic supply hub that could lower transportation costs and mitigate geopolitical supply shocks. In a market where copper prices remain volatile, Gunnison’s disciplined approach to data collection and resource definition may set a benchmark for other U.S. copper developers.
