Highlights

  • Infinity Mining has executed a binding farm-in and joint venture agreement with Mining One Pty Ltd over its Tanjil Bren (EL7357) and Walhalla South Extended (EL7356) projects in Victoria, with Mining One funding up to ~$500,000 in two stages to earn up to a 51% interest — providing Infinity with a fully funded exploration pathway at no direct cost to the company.
  • Walhalla South Extended is identified as an immediate high-priority target, with previous surface rock chip sampling returning high-grade antimony assays of 21.6% to 51.4% Sb and anomalous gold from 0.051 to 0.88g/t Au, with field follow-up confirming outcropping quartz-stibnite veining associated with an untested ~1.5km circular magnetic high interpreted as a sub-vertical intrusion.
  • With IMI shares trading at $0.008 as of 27 April 2026, the company's market capitalisation reflects a micro-cap profile; the JV structure with Mining One allows Infinity to retain exploration exposure across the Victorian tenements while deploying capital toward its higher-priority gold and copper projects, including the Cangai Copper Project with its binding technology agreement.

Infinity Mining Limited (ASX:IMI) is a diversified mineral exploration company with tenement holdings exceeding 3,700 square kilometres across New South Wales, Victoria, and the East Pilbara in Western Australia. The company's focus spans copper, gold, and critical minerals, with the Cangai Copper Project in NSW's Macquarie Arc representing its most advanced asset. As of 27 April 2026, IMI shares were trading at $0.008.

The announcement on 27 April 2026 of a binding farm-in and joint venture agreement with Mining One Pty Ltd over the Victorian gold-antimony tenements represents a capital-allocation decision by Infinity's board to advance prospective assets without direct cash expenditure, while retaining upside exposure through a retained minority interest in any resulting discovery. The strategic logic — deploying a well-credentialed technical partner's capital to advance non-core projects while the company focuses on its flagship assets — is consistent with the resource exploration industry's established model for capital-efficient project advancement.

The Victorian Gold-Antimony Portfolio: Geological Setting

The Tanjil Bren and Walhalla South Extended tenements are situated in the Eastern Victorian goldfields, within the Melbourne Zone of the Lachlan Fold Belt — a geological province with a well-documented history of gold and antimony mineralisation. The projects are interpreted as prospective for structurally controlled gold-antimony systems, a deposit style characterised by the co-occurrence of gold and stibnite (antimony sulphide) within quartz veins hosted in fold-and-fault structures. Victorian gold-antimony deposits of this type have been the subject of renewed exploration interest, partly driven by antimony's classification as a critical mineral in several jurisdictions including Australia, the United States, and the European Union.

At Tanjil Bren, historical stream sediment re-assaying returned anomalous gold values in 34 of 95 samples, with a peak of 70ppb Au and elevated pathfinder elements including bismuth, tin, tungsten, lead, and antimony — indicators consistent with an intrusion-related gold system (IRGS) exploration model. At Walhalla South Extended, rock chip sampling has returned high-grade antimony results of up to 51.4% Sb with anomalous gold values, with confirmed quartz-stibnite veining at the surface.

The Circular Magnetic Target: An Untested High-Priority Feature

One of the most technically compelling features at Walhalla South Extended is the identification of a circular magnetic high target approximately 1.5 kilometres in diameter, interpreted from geophysical data as a sub-vertical intrusion. This type of magnetic signature, when co-located with surface geochemical anomalies and structural indicators of mineralisation, is commonly associated with carbonatite or alkaline intrusions that can act as thermal drivers for mineralising fluid systems. Critically, this circular magnetic target has not been drill-tested, making it a compelling near-term exploration objective within the Stage 1 program.

Mining One has specifically identified the Walhalla South Extended target as an immediate high priority within the joint venture's work program, consistent with Infinity's own assessment that the combination of confirmed high-grade rock chips, quartz-stibnite veining, and the untested magnetic anomaly represents a material exploration opportunity warranting systematic drill testing.

Farm-In Structure: Financial Terms and Implications

The farm-in agreement operates across two stages. In Stage 1, Mining One will fund $200,000 of exploration expenditure within 12 months to earn a 25% interest in both tenements. In Stage 2, Mining One will fund a minimum 1,500-metre RC or diamond drilling program estimated at $300,000 within 12 months of completing Stage 1, increasing its interest to 51%. Total estimated expenditure across both stages is approximately $500,000. During the earn-in period, Mining One is also responsible for maintaining tenement expenditure obligations.

For Infinity shareholders, the key feature of this arrangement is that the company retains a 49% participating interest in the Victorian tenements without contributing any exploration expenditure through the earn-in phase. This free-carry structure during the earn-in period means that Infinity benefits from any exploration success — including the potential identification of a drill-ready target at the circular magnetic anomaly — without diluting its cash reserves. Upon completion of the earn-in, the parties form an unincorporated joint venture with Infinity as a 49% participant, with standard dilution provisions applying to subsequent work programs.

About Mining One: Partner Credentials

Mining One is an independent, employee-owned mining consultancy with over 80 technical professionals and a global operational footprint, providing services across geology, geotechnical engineering, mining engineering, metallurgy, and environmental disciplines. The firm has specific experience in structurally controlled gold-antimony systems, directly applicable to the Tanjil Bren and Walhalla South Extended geological settings. Their Geology Manager Stuart Hutchin commented publicly on the prospectivity of the licences and the mutual interest in developing additional joint venture arrangements with Infinity beyond the Victorian tenements.

Antimony's Critical Mineral Status: A Macro Context

Antimony's reclassification as a critical mineral by multiple Western governments has elevated the strategic profile of antimony exploration globally. The metal is used in flame retardants, semiconductor production, ammunition, and increasingly in energy storage applications. China accounts for the dominant majority of global antimony production, and Western supply chain concerns around this concentration have driven policy-level interest in developing alternative sources. For Infinity Mining, the high-grade antimony results at Walhalla South Extended — up to 51.4% Sb in rock chips — place the project in a favourable policy context, even at this early stage of exploration.

Conclusion

Infinity Mining's execution of a binding farm-in and joint venture agreement with Mining One over its Victorian gold-antimony projects on 27 April 2026 is a strategically coherent step for a micro-cap explorer seeking to advance a portfolio of projects with limited cash resources. By securing a funded exploration pathway at no direct cost to the company, Infinity retains upside exposure to what could be a material discovery at the high-grade Walhalla South Extended target, while preserving capital for its flagship assets. At a share price of $0.008, investor attention will focus on Stage 1 field results and — most critically — the results of the first drill program targeting the untested circular magnetic anomaly.
