G50 Corp Validates 1.8km Gold-Silver Strike at Arizona's Golconda Project with Expanding Gallium Potential

Gold, Silver, and Gallium Mineralisation Confirmed Over 1.8 Kilometres in Tub Structural Zone

Final assay data from G50 Corp’s 2025–2026 drilling confirm continuous gold, silver, and gallium mineralisation along a 1.8-kilometre strike at the Golconda Property. This marks a major advancement in defining the Tub Structural Zone, a prominent northwest-trending crustal feature hosting significant district-scale base and precious metals. Mineralisation occurs within multiple sub-parallel polymetallic quartz-sulphide veins—including the Golconda, Primrose, Tub, Green Linnet, Good Hope, and Mexican veins—each exhibiting varying gold, silver, zinc, lead, and copper ratios.

The company completed 54 reverse circulation and 9 core drill holes, documenting mineralised widths up to 400 metres from surface, remaining open both at depth and along strike. This extensive mineral footprint confirms the district-scale nature of the discovery and highlights substantial exploration upside. The broad alteration halo—dominated by sericite and kaolinite from hydrothermal feldspar alteration—is consistently linked with gallium mineralisation, adding a strategic metals dimension to the asset.

Golden Eagle Target Yields Significant Shallow High-Grade Gold and Silver Intercepts

Four angled RC drill holes (GRC51–54) at the Golden Eagle target in the project’s northwest delivered outstanding shallow precious metal results, expanding the known mineralisation along the Tub Structural Zone. Located about 250 metres northwest of prior drillholes GRC45–46, Golden Eagle confirms mineralisation continuity and includes some of the highest-grade intercepts to date, especially near surface where mining access may be optimal.

Key intercepts include 21.3 metres grading 3.72 g/t gold and 28.76 g/t silver from 36.6 metres in GRC54, with a higher-grade subsection of 10.7 metres at 7.25 g/t gold and 49.82 g/t silver. Drillhole GRC51 returned 13.7 metres at 5.42 g/t gold and 112.58 g/t silver from 64 metres, plus 3.0 metres at 4.29 g/t gold and 814.0 g/t silver from 10.7 metres, demonstrating very high silver grades in discrete zones. These results indicate Golden Eagle hosts both broad lower-grade and discrete high-grade zones warranting further detailed exploration.

Green Linnet Vein Extensions Confirmed Up-Dip and Along Strike

Two angled RC holes (GRC49–50) tested shallower up-dip and strike extensions of the Green Linnet Vein near core hole GDD09. Previously, GRC06 intersected 35.0 metres at 5.2 g/t gold and 5.9 g/t silver from 176.8 metres, while GDD09 hit 1.5 metres at 11.2 g/t gold and 267 g/t silver from 185.9 metres. New drilling confirmed geological and mineralisation continuity at shallower depths, important for future development potential.

GRC49 recorded 18.3 metres at 0.41 g/t gold and 3.0 g/t silver from 70.1 metres, including 4.6 metres at 1.22 g/t gold and 8.0 g/t silver. GRC50 intercepted 1.5 metres at 3.67 g/t gold, 37.5 g/t silver, and 1.2% zinc from 29.0 metres, plus 9.1 metres at 1.12 g/t gold, 17.9 g/t silver, and 0.4% zinc from 85.3 metres, including 7.6 metres grading 1.31 g/t gold, 20.3 g/t silver, and 0.4% zinc. The company highlighted remaining opportunities to test the Good Hope Vein’s strike extension westward, previously intersected at 16.8 metres grading 4.34 g/t gold and 68.8 g/t silver from 216.4 metres in GDD09.

Gallium-Bearing Alteration Halo Adds Strategic Metals Value

Drilling confirmed extensive gallium mineralisation within the Tub Structural Zone, supporting G50 Corp’s strategy to develop a domestic gallium supply alongside precious and base metals. Gallium is a critical material for the US, and integrating its recovery into a gold-silver-zinc operation could boost the Golconda Project’s economic and strategic profile. Gallium occurs within the broad sericite-kaolinite alteration halo characteristic of the hydrothermal system along the Tub Structural Zone, indicating a systemic association with the precious and base metal veins.

Recent drill results include gallium intercepts of 213 metres at 17.6 g/t from surface in GRC47, 213 metres at 20.6 g/t from surface in GRC48, 203 metres at 18.0 g/t from surface in GRC51, and 450 metres at 19.8 g/t from 1.1 metres in GDD08. These extensive near-surface to 450-metre-depth intervals suggest potential for gallium recovery in future processing. The company noted that further metallurgical testing, geological analysis, and economic studies are essential to assess the technical and commercial viability of development, including gallium extraction economics.

Polymetallic Vein System Hosts Gold, Silver, Zinc, Lead, and Copper

The Golconda Project lies on a district-scale northwest-trending crustal structure featuring multiple sub-parallel polymetallic quartz-sulphide veins with varying gold, silver, zinc, lead, and copper content. This complex hydrothermal system along the Tub Structural Zone creates multiple development opportunities depending on metal prices, mining costs, and processing economics. The six named vein systems—Golconda, Primrose, Tub, Green Linnet, Good Hope, and Mexican—demonstrate mineralisation distributed across a broad structural corridor, expanding project scale and resource potential.

Adjacent to Golconda is the Mineral Park porphyry copper-silver-molybdenum mine, providing regional geological context and confirming significant district mineralisation. The Tub Structural Zone’s confirmed 1.8-kilometre extent and widths up to 400 metres establish it as a key regional target within the metallogenic province. The polymetallic nature means economic assessments must consider combined revenue from multiple metals, potentially enhancing project economics versus single-commodity gold or silver operations.

2025–2026 Drilling Program Achieves All Exploration Goals

G50 Corp’s 2025–2026 drilling program targeted three objectives: follow-up on high-grade gold and silver intercepts from 2023 and 2025, extend knowledge of mineralisation below 180 metres, and explore new targets along the Tub Structural Zone. The company reports all objectives were successfully met, validating the exploration strategy and drilling execution. This comprehensive drilling phase lays a strong technical foundation for further evaluation and target generation.

High-grade intercepts from 2023 and 2025 included 35.0 metres at 5.2 g/t gold and 5.9 g/t silver from 176.8 metres in GRC06, with additional mineralisation continuity confirmed in 2025 drillholes GRC21 and GRC22. Depth extension drilling demonstrated mineralisation to at least 450 metres, remaining open deeper, indicating significant exploration upside. New target exploration at Golden Eagle expanded the mineralised footprint northwestward, opening fresh Tub Structural Zone areas for investigation.

Strategic Focus on Domestic Critical Metals Supply

G50 Corp’s Golconda Project strategy integrates precious and base metals exploration with a focus on domestic supply of critical strategic materials. The emphasis on gallium recovery within a primary precious and base metals project aligns with industry trends toward multi-commodity assets that enhance supply chain resilience while generating diversified revenue streams. This approach may increase appeal to development partners, financiers, and government bodies supporting domestic strategic mineral production.

The company acknowledges gallium’s geopolitical importance for semiconductors, photovoltaics, and defense, potentially offering additional development incentives and favorable regulatory or financing conditions compared to traditional gold-silver projects. However, G50 Corp prudently notes that further metallurgical, geological, and economic studies are required to confirm technical and commercial feasibility, reflecting the significant capital and technical challenges of new mine development despite demonstrated mineralisation and strategic metals potential.

Upcoming Steps: Geological Model Refinement and Target Prioritisation

Following completion of the 2025–2026 drilling and receipt of final assays, G50 Corp plans to update and refine the geological model of the Tub Structural Zone. This model will integrate all mineralisation data, geometry, grade distribution, and structural controls, serving as the basis for identifying and prioritising new drilling targets to test mineralisation continuity along strike and at depth.

Future work will focus on generating new drill targets, emphasizing strike extensions of known veins, deeper mineralisation beyond current drill depths, and new targets along the Tub Structural Zone. The company highlighted specific opportunities such as testing the Good Hope Vein’s western strike continuation. Timing and scope of future drilling will depend on funding, operational priorities, and management’s evaluation of the most promising targets. Investors should watch for updates on exploration progress and any material changes to geological interpretations.
