Infinity Mining Reports High-Grade Antimony-Gold Mineralisation Over 500m at Tanjil Dome Prospect in Victoria

Infinity Mining's Exploration Strategy and Assets in Eastern Victoria

Infinity Mining Limited holds exploration tenements across the Eastern Victorian goldfields, a region historically known for structurally controlled gold-antimony mineralisation. The company’s tenements, Tanjil Bren (EL7357) and Walhalla South Extended (EL7356), are interpreted to host mineralisation styles similar to other established gold-antimony systems in Victoria. The Tanjil Dome Prospect lies within these tenements, approximately 100 kilometres from the Sunday Creek project, enabling Infinity to leverage existing infrastructure and geological expertise across this prospective belt.

Infinity’s exploration approach targets high-grade antimony and gold systems within structurally prepared terranes. The Eastern Victorian goldfields are a proven mining district with historical production and documented mineralisation styles that provide a solid foundation for systematic exploration. The joint venture with Mining One Consultants, a respected exploration consultancy, reflects Infinity’s commitment to accessing specialist geological expertise to advance exploration and identify new prospects within its tenure.

Exceptional Antimony Assays and Gold-Bearing Quartz Vein Findings at Tanjil Dome

Surface rock sampling at Tanjil Dome has yielded significant assay results, confirming high-grade antimony mineralisation accompanied by gold. A laminated quartz vein sample collected at approximately 5794857N, 433533E, 320 mRL returned 5.32% antimony and 1.35g/t gold. This laminated quartz vein texture indicates repeated hydrothermal fluid flow and vein formation, consistent with a structurally controlled mineralising system capable of concentrating both antimony and gold.

Massive stibnite vein samples demonstrate substantial antimony mineralisation within vein structures. One sample at 5794856N, 433533E, 320 mRL returned 48.3% antimony and 0.04g/t gold, while another nearby sample at 5794856N, 433532E, 320 mRL returned 41.6% antimony and 0.37g/t gold. The highest assay from the program reached 48.7% antimony with 1.35g/t gold from quartz-vein samples, highlighting the prospect’s potential grade.

Soil Geochemical Survey Reveals 500-Metre Antimony-Arsenic Anomaly

Orientation soil sampling along existing logging tracks tested magnetic anomalies across the Tanjil Bren and Walhalla South Extended tenements, where high-grade stibnite was previously found. Using a 50m by 50m grid, the soil survey identified a coherent antimony-arsenic geochemical anomaly extending over at least 500 metres. Peak portable X-ray fluorescence (pXRF) readings recorded 751 ppm antimony and 791 ppm arsenic.

Laboratory gold assays from soil samples reached up to 177 parts per billion gold, confirming anomalous gold associated with the broader antimony-arsenic signature. The anomaly’s extent suggests mineralisation is not confined to a single surface occurrence but represents a broader hydrothermal system with lateral continuity. Additional orientation soil lines are underway. Arsenic anomalies located 2 kilometres east and 4 kilometres north within EL7357 indicate multiple mineralised systems within the tenements, warranting systematic exploration.

Diverse Mineralisation Styles Support Structurally-Controlled Hydrothermal Model

Exploration at Tanjil Dome identified antimony mineralisation in various geological settings, supporting a large structurally-controlled hydrothermal system. Besides laminated quartz veins and massive stibnite veining, stibnite-bearing breccia hosted by altered dyke material was recovered. A breccia sample at 5794857N, 433532E, 320 mRL returned 45.3% antimony and 0.07g/t gold, showing mineralisation extends beyond quartz veins into brecciated intrusive rocks, consistent with hydrothermal fluids along structural contacts.

The combination of laminated quartz veins, massive stibnite veins, mineralised breccias, altered dykes, and coherent soil geochemistry with gold-bearing mineralisation forms a robust geological framework for a structurally controlled antimony-gold hydrothermal system. The presence of gold, confirmed by the 1.35g/t assay from quartz veins, indicates a polymetallic system capable of concentrating both commodities. Such systems often extend to significant depths and lateral distances, offering potential for economic mineralisation through systematic follow-up.

Joint Venture with Mining One Consultants Enhances Geological Expertise

Infinity Mining’s joint venture with Mining One Consultants supports systematic exploration of the Tanjil Bren and Walhalla South Extended tenements. Mining One’s geological expertise underpins the discovery and characterisation of Tanjil Dome. Geology Manager Stuart Hutchin highlighted that high-grade stibnite mineralisation aligns with a coherent antimony-arsenic soil anomaly, gold-bearing laminated quartz veins, mineralised breccias, and altered dykes, endorsing a structurally controlled hydrothermal mineralisation model.

Mining One’s involvement grants Infinity access to specialist geological knowledge and exploration methodologies for the Eastern Victorian goldfields. The joint venture structure enables Infinity to advance exploration while managing operational and financial commitments. Although early-stage, the Tanjil Dome Prospect has progressed materially, with initial exploration suggesting potential for a gold-antimony deposit. This expert validation supports further resource allocation for follow-up work.

Upcoming Exploration: Soil Sampling, Mapping, Trenching, and Drill Targeting

Infinity Mining reports the Tanjil Dome system remains open with pending laboratory assays from recent programs. Planned follow-up includes extending soil sampling beyond the current 500-metre anomaly to assess lateral continuity. Structural mapping will identify controls on mineralisation and refine the hydrothermal model. Trenching is planned to collect samples beneath weathered surfaces.

The company is also targeting additional anomalies within its tenements, including arsenic anomalies 2 kilometres east and 4 kilometres north. Drill target definition is the ultimate goal, with specific hole locations and depths to be developed based on geological, geochemical, and structural data. This systematic approach aims to optimise drilling effectiveness. Pending assay results will further guide planning.

Recent Capital Raise via EG1 Share Sale Supports Exploration Funding

Infinity Mining recently sold EG1 shares from its investment portfolio, generating approximately $182,000 in cash proceeds. This capital supports ongoing exploration and operations. The company retains about $133,000 worth of EG1 shares at last traded prices, maintaining exposure to potential future liquidity. This partial divestment reflects a strategy to manage investments while funding exploration advancement.

The timing of this capital raise aligns with the Tanjil Dome results announcement, positioning Infinity to fund planned follow-up programs including soil sampling, mapping, and trenching. Retaining remaining EG1 shares preserves optionality for future realisation depending on market conditions, balancing near-term funding needs with potential upside.

Regional Geological Context and Proximity to Established Gold-Antimony Deposits

The Tanjil Dome Prospect lies within the Eastern Victorian goldfields, a historically productive mining region with major gold-antimony deposits. Proximity to these established deposits supports the prospectivity of Infinity’s tenements. The region is part of the Melbourne Zone, known for mineralisation styles analogous to those targeted by Infinity. This regional context provides a proven mineral systems framework for evaluating Tanjil Dome.

Structural and lithological features at Tanjil Dome align with other documented structurally controlled gold-antimony systems in Victoria, validating the exploration model. Located about 100 kilometres from the Sunday Creek project, Infinity can pursue integrated regional exploration strategies and potential economies of scale across multiple prospects. The regional setting reinforces the view that Tanjil Dome offers a significant exploration opportunity within a proven mineralisation domain.

Sector Outlook for Antimony-Gold Exploration in Eastern Victoria

Exploration of antimony-gold systems in Eastern Victoria addresses growing international demand for antimony, a strategic industrial mineral used in flame retardants, alloys, and other applications. Supply chain security is a strategic concern for many developed economies. The Eastern Victorian goldfields’ history of antimony and gold production establishes the region as a credible source. Infinity Mining’s focus positions it to contribute to domestic antimony supply development if significant ore-grade deposits are defined.

Gold exploration remains central to Australian junior explorers, with antimony providing additional economic leverage. The presence of anomalous gold within the antimony system at Tanjil Dome offers multi-commodity upside. This polymetallic prospect aligns with industry trends toward multi-commodity systems offering economic optionality. Infinity’s systematic characterisation of Tanjil Dome exemplifies best-practice exploration within the Australian junior sector.

Risks and Challenges for Tanjil Dome Prospect and Infinity Mining

Junior explorers face inherent risks, including uncertainty whether surface mineralisation extends at economic grades to depth, potential failure to define economically viable resources, and market condition fluctuations during exploration. Tanjil Dome is early-stage with no drilling yet, so mineralisation geometry, vertical continuity, and true widths remain unknown. Pending assays may confirm or constrain economic potential. Defining drill targets and securing drilling funding are critical milestones.

Infinity’s ability to finance ongoing exploration depends on capital availability and market conditions. Recent EG1 share sales provide short-term funding but do not ensure long-term sustainability. Exploration licenses in Victoria require renewal and compliance; regulatory changes could impact exploration activities. As an early-stage company, investors should acknowledge exploration uncertainties and that most programs do not yield economic mineral resources.
