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

CEO Perspective
Strategy behind the next phase of drilling, BS-4A
From Discovery to Expansion: Advancing Toward BS-4A
Following the BS-3 discovery, Bell Copper is advancing step-out drilling to expand the footprint of the system and test its full scale.

Big Sandy Project Overview
Overview of Bell's 100%-owned Big Sandy project.
Eastern MT Target Overview
Testing two stacked targets with a single drill hole.
Perseverance Project
Hole K-24 is designed to test two distinct stacked targets within the Perseverance system. The upper target comprises the Eastern MT Anomaly identified in 2020, while the lower target evaluates a structural concept analogous to the setting associated with Bell Copper's BS-3 discovery at Big Sandy.
This drilling is being completed in addition to the broader MMDEX exploration program planned for Perseverance.

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.
