G50’s Gallium and Antimony Discoveries Could Reshape US Strategic Metals Supply

Significant Precious Metals Discovery at Golconda

G50 Corp’s September 2025 quarterly activities report highlights a breakthrough in exploration at its flagship Golconda Project in Arizona. Recent drilling confirmed a new precious metals discovery with notable intercepts such as 47.2 meters grading 2.0 grams per tonne gold, 40.2 grams per tonne silver, and 0.29% zinc. These results extend over a strike length exceeding 700 meters within the Tub Zone, a major structural corridor known for hosting polymetallic mineralisation.

The drilling program also intersected consistent and significant gallium mineralisation, with assays showing grades up to 21.7 grams per tonne gallium near surface. Importantly, metallurgical test work by SGS Lakefield confirmed that 85–92% of the gallium is hosted in sericite, a form of muscovite, which bodes well for conventional processing and potential commercial extraction.

White Caps Project Delivers High-Grade Antimony and Gold

In Nevada, G50’s maiden scout drilling at the White Caps Project returned encouraging results, including exceptionally high antimony grades peaking at 3.5% over narrow intervals, alongside broad zones of gold mineralisation. This project, historically a high-grade gold mine with production averaging around 30 grams per tonne, lies adjacent to the Manhattan Gold Mine and near the Round Mountain Gold Mine, positioning it in a prolific mining district.

The drilling results support G50’s geological model that high-grade mineralisation occurs where steep faults intersect limestone units, providing pathways for gold, silver, and antimony mineralising fluids. The company plans further drilling to delineate these zones and better understand the antimony’s extent and economic potential.

Corporate and Financial Position Strengthened

To support its aggressive exploration agenda, G50 completed a A$10 million institutional placement during the quarter, bolstering its cash reserves to A$9.1 million. This funding enables ongoing core and reverse circulation drilling, metallurgical testing, and baseline environmental studies at Golconda. Additionally, G50 commenced trading on the OTCQB market under the ticker GFTYF, enhancing its visibility among US investors.

Managing Director Mark Wallace emphasised the strategic importance of the discoveries, noting the potential for domestic US supply of critical metals like gallium and antimony, which are vital for energy security and advanced technologies.

Looking Ahead

With exploration expenditure exceeding A$2 million this quarter and no mining production yet, G50 remains focused on advancing its projects through detailed drilling and metallurgical studies. The company’s ability to unlock the commercial potential of its gallium discovery at Golconda and to expand the high-grade antimony and gold zones at White Caps will be key milestones in the coming months.
