Infinity Mining Reports 500-Metre High-Grade Antimony-Gold Soil Anomaly at Victoria's Tanjil Dome

High-Grade Antimony Mineralisation Verified Across Multiple Geological Environments at Tanjil Dome

Infinity Mining's initial exploration at Tanjil Dome has confirmed high-grade antimony mineralisation across various geological settings. Fieldwork identified stibnite-bearing quartz veins, massive stibnite veins, and stibnite-bearing breccias within altered dyke material, all exposed at surface within the soil geochemical anomaly. This diversity suggests a broad hydrothermal system with multiple mineralisation pathways rather than a single occurrence.

Rock samples revealed significant antimony grades: a laminated quartz vein sample contained 5.32% antimony and 1.35 g/t gold; massive stibnite vein samples showed 48.3% antimony with 0.04 g/t gold, and 41.6% antimony with 0.37 g/t gold; a stibnite breccia in altered dyke material returned 45.3% antimony and 0.07 g/t gold. These results support a structurally-controlled hydrothermal mineralising system with economic potential.

Extensive Soil Geochemical Anomaly Defines 500-Metre Exploration Target at Tanjil Dome

Orientation soil sampling across Tanjil Dome revealed a coherent antimony-arsenic soil anomaly extending at least 500 metres, with exploration open at its edges. Peak pXRF values reached 751 ppm antimony and 791 ppm arsenic. Laboratory gold assays from soil samples showed up to 177 parts per billion gold, confirming the soil signature reflects underlying antimony and gold mineralisation. This large anomaly indicates a broad mineralised system with multiple targets for further exploration.

Additional arsenic anomalies were detected 2 kilometres east and 4 kilometres north within the EL7357 tenement, suggesting further prospective zones within Infinity's tenure. Ongoing orientation soil sampling lines indicate active systematic exploration to better define these anomalies. The anomaly's size and continuity provide a strong foundation for drill-targeting and follow-up work.

Gold-Bearing Quartz Veins Highlight Polymetallic Potential at Tanjil Dome

The presence of anomalous gold within the Tanjil Dome hydrothermal system enhances the prospect's economic appeal. A laminated quartz vein sample returned 1.35 g/t gold, confirming gold within the surface mineralisation. The laminated texture suggests repeated hydrothermal fluid flow and vein development, consistent with a structurally-controlled mineralising event producing both antimony and gold. This polymetallic mineralisation increases the potential value of any deposit identified.

The highest gold equivalent value recorded was 167.1 AuEq, combining antimony and gold assay results. This underscores the economic significance of both metals at Tanjil Dome. The coexistence of gold-bearing quartz veins and high-grade antimony suggests a compound mineralisation system similar to other gold-antimony deposits in the Eastern Victorian goldfields.

Strategic Positioning Within Victoria's Gold-Antimony Mineral Province

Tanjil Dome lies within the Eastern Victorian goldfields, about 100 kilometres from Infinity Mining's Sunday Creek gold-antimony project. The tenements, Tanjil Bren (EL7357) and Walhalla South Extended (EL7356), are located in Victoria's Melbourne Zone and are prospective for structurally-controlled gold-antimony mineralisation analogous to regional systems. Proximity to established gold-antimony districts and major deposits strengthens the exploration potential of this new prospect and Infinity's broader tenure.

The Eastern Victorian goldfields have a proven history of gold and antimony production from structurally-controlled hydrothermal systems, providing a robust mineral systems model for Tanjil Dome. Similar mineralisation styles likely operate across multiple tenements in the district. Infinity's strategic focus on gold and antimony exploration within this productive province, along with its Sunday Creek project, positions the company to capitalize on exploration success and potential development synergies.

Joint Venture with Mining One Consultants Drives Exploration Progress

Infinity Mining formed a joint venture with Mining One Consultants to advance exploration at Tanjil Dome. Mining One's geology team completed the initial program that defined the high-grade antimony-gold anomaly and soil geochemical signature. Mining One Geology Manager Stuart Hutchin highlighted the association of high-grade stibnite with a coherent antimony-arsenic soil anomaly, gold-bearing laminated quartz veins, mineralised breccias, and altered dyke material, supporting a structurally-controlled hydrothermal model. This partnership enables Infinity to leverage expert technical support while retaining asset control.

Mining One Consultants is a respected specialist in gold and antimony systems. The joint venture structure allows Infinity to conduct rigorous exploration without expanding internal geology staff permanently. Both parties share exploration costs and potential benefits from discoveries. Executive Chairman Cameron Petricevic stated the results mark a significant advancement, positioning Tanjil Dome as a substantial gold-antimony target warranting systematic follow-up.

Upcoming Exploration and Drill-Targeting Plans at Tanjil Dome

Infinity Mining plans several follow-up exploration phases at Tanjil Dome, including expanded soil sampling to better define anomaly boundaries, structural mapping to identify controlling faults and fractures, trenching to expose subsurface mineralisation, and identification of new targets within the tenement. Laboratory assays from initial samples are pending and will inform further planning. Drill-target definition is the next key milestone, supported by existing surface data.

The Tanjil Dome system remains open, indicating mineralisation extends beyond currently sampled zones. Surface rock samples, soil anomalies, and visible mineralisation suggest the prospect merits systematic exploration to refine drill targets. Geological observations provide a clear path for follow-up and drilling, reflecting management’s confidence and commitment. Timing depends on capital availability and operational scheduling.

Enhanced Cash Position Through EG1 Share Sale

Infinity Mining recently sold shares in EG1, a non-core investment, generating approximately $182,000 in additional cash to support exploration and operations. The company still holds about $133,000 worth of EG1 shares at last traded price, maintaining some exposure while unlocking capital for core activities. This demonstrates prudent capital management by converting non-core assets into working capital.

This share sale aligns with the expansion of exploration at Tanjil Dome and prioritizes funding for follow-up work including soil sampling, structural mapping, trenching, and drill-targeting. The selective realisation balances capital needs with maintaining investment exposure.

Mineral Systems Model Supports Structurally-Controlled Hydrothermal Mineralisation

Exploration findings at Tanjil Dome align with a structurally-controlled hydrothermal mineralisation model, evidenced by the association of stibnite veining, gold-bearing quartz veins, brecciation, and altered dyke material within the anomaly. The diverse mineralisation styles and coherent soil anomaly indicate a single hydrothermal event created multiple mineralisation pathways in structurally prepared host rocks. The laminated quartz vein textures reflect repeated hydrothermal fluid flow and episodic vein formation, typical of structurally-controlled systems. Stibnite, dyke alteration, and brecciation suggest hydrothermal fluids focused along structurally prepared intrusions, characteristic of productive gold-antimony systems.

This interpretation is consistent with regional geological models for the Eastern Victorian goldfields, where structurally-controlled gold-antimony deposits are well documented. The characteristics observed at Tanjil Dome match economic gold-antimony deposits in the region. The mineral systems approach guides systematic exploration and supports drill-testing as the logical next step to assess economic potential.

Early-Stage Prospect Status and Exploration Risk Considerations

Infinity Mining classifies Tanjil Dome as an early-stage antimony-gold hydrothermal target. While initial results are encouraging, no mineral resource estimate or drilling has been completed, and mineralisation extent at depth remains unknown. Current data is from surface sampling and soil geochemistry, which support further exploration but do not confirm a mineable ore body or define deposit geometry, grade distribution, or tonnage. Laboratory assays are pending for full mineralisation characterisation.

Advancing Tanjil Dome to a drill-ready stage depends on completing follow-up exploration, including structural mapping and drill target refinement. Environmental and regulatory approvals may also be required before drilling. The development timeline, capital needs, and economic viability remain uncertain and rely on exploration results and market conditions affecting gold and antimony sectors.
