Proven Geology &
High-Grade Gold Zones
Copper–gold mineralization verified across a century of professional reports, assays, and modern metallurgical testing.
Geological Setting
The Swallow Mine lies within Arizona’s Castle Creek Mining District, where mineralization is hosted primarily in faulted and brecciated zones within metamorphic rocks and along granite contacts. Multiple campaigns have mapped copper oxides, free-milling gold, and quartz–iron oxide veining, with structures remaining open along strike and at depth.
District & Access
Located in central Arizona with all-season road access. The property benefits from nearby infrastructure and on-site water, enabling efficient exploration and small-scale test work.
Host Rock & Mineralization
Mineralization occurs in fractures, shear zones, and brecciated contacts where quartz veins and disseminated sulfides have deposited copper and gold. The combination of high-grade shoots and wider, lower-grade halos creates opportunities for selective mining and bulk tonnage scenarios.
Structural Controls
Faults and fractures have acted as fluid pathways, depositing gold and copper along multiple orientations. The veins remain open at depth, suggesting potential for additional mineralized zones below the historically worked areas.
Verification Across Decades
- 1991 – Phelps Dodge (Skyline Labs) confirms multiple high-grade gold channel samples up to 68.8 g/t Au.
- 2001 – Ahlers Assay Office confirms gold up to ~32.6 g/t Au from owner-submitted samples.
- 2009 – MSRDI flotation tests achieve 90–95% gold recovery into rich concentrates.
- 2012 – BNR003 program confirms gold up to 79.1 g/t Au by FA/Gravimetric.
- 2013–2015 – Modern geologic mapping and FLSmidth work confirm recoverability and expansion potential.
