Green & Gold Minerals Rock Chips Flag Mt Gossan and Siberia as Choice Drilling Areas

Why It Matters

If drilling confirms these grades, Green & Gold could add a sizable copper‑indium‑silver resource to Queensland’s portfolio, attracting capital and diversifying the state’s traditionally tin‑focused mining sector.

Key Takeaways

• Rock chips show up to 24% Cu and 576 g/t In
• Mt Gossan breccia spans 210 m by 125 m, never drilled
• Siberia lode has historic 2.6% Cu, 39 g/t Ag intersections
• Drilling slated for Copper Hills in May 2026, then Mt Gossan
• Project sits within Herberton Tin Field, a known mineral corridor

Pulse Analysis

Queensland’s Herberton Tin Field has long been synonymous with tin, but Green & Gold Minerals is reshaping that narrative. Recent rock chip sampling at the Herberton Conductor Metals project uncovered a suite of high‑grade copper, silver, tin and, notably, indium—an increasingly valuable metal for semiconductor manufacturing. The presence of up to 24% copper and over half a kilogram per tonne of indium suggests a vertically integrated, multi‑metal deposit that could rival other Australian copper‑indium projects, positioning the region as a potential hub for critical minerals.

The geological picture is equally compelling. Mt Gossan’s breccia zone, extending 210 metres in length and 125 metres in width, remains untouched by drilling, offering a rare opportunity to test thickened breccia‑style mineralisation. Meanwhile, the Siberia lode, with a continuous 5‑kilometre outcrop and historic drill hits of 2.6% copper and 39 g/t silver, aligns with magnetic anomalies that hint at deeper, undiscovered ore bodies. These data points, combined with elevated indium values across all samples, provide a strong basis for a sizable resource model that could support long‑term production.

Looking ahead, Green & Gold’s drilling agenda underscores its confidence. After a May 2026 program at the Copper Hills prospect, the company will pivot to the newly identified Mt Gossan and Siberia targets, aiming to delineate a resource that could feed both domestic smelters and export markets. Successful results would not only boost the company’s valuation but also reinforce Australia’s strategic push to secure supply chains for critical metals, drawing heightened interest from global investors seeking exposure to the next generation of base‑metal projects.
