DISCOVERY HIGHLIGHT
BS-3: The Hole That Changed the Story
BS-3 confirmed the presence of a large concealed porphyry copper system at Big Sandy, establishing the foundation for ongoing expansion drilling and technical advancement.
Big Sandy Porphyry Discovery Presentation — Tim Marsh (CEO & Chief Geologist), Arizona Geological Society, September 6, 2022
Highlights
- 200 m @ 0.42% Cu, 2.4 g/t Ag
- Includes 54 m @ 0.67% Cu
- Confirms concealed porphyry system
- Mineralization at significant depth

U.S. CRITICAL MINERALS OPPORTUNITY
This Isn’t Just Copper —
This Is a U.S. Critical Minerals Story
The Big Sandy Project is advancing as more than a traditional copper exploration program. Metallurgical testing confirms high recoveries and strong mineralization characteristics.
82–84% recovery
~25% concentrate grade
Copper
~130 g/t
~68% recovery
Silver
~1,700 g/t (est.)
in molybdenite
Rhenium
In addition to copper, associated metals including silver and rhenium contribute to the project’s strategic importance within the U.S. critical minerals landscape.
Copper extraction up to 96% achieved in leach testing.
Why It Matters
Strong copper recoveries, combined with silver and rhenium potential, position Big Sandy as a strategically relevant development opportunity within a nationally significant mineral corridor.
