Highlights

  • Channel sampling at Tanjil Dome in Victoria identified antimony-rich material with associated gold at surface.
  • The sampling work covered a limited portion of a broader gold-antimony geochemical anomaly.
  • True widths, depth continuity and metallurgical recoveries have not been established.
  • The joint venture is refining targets and preparing work plans ahead of possible maiden drilling.

Infinity Mining Limited (ASX:IMI) is a mineral explorer with Australian copper, gold and antimony interests. At its Tanjil Dome project in eastern Victoria, the company has reported surface channel assays showing antimony-rich material accompanied by gold. This is an early exploration result, rather than evidence of a defined deposit. The new field information is being used to plan potential drilling, with geometry, metallurgical performance and the extent of mineralisation all still unresolved.

Channel Results Define a Surface Target

The initial programme sampled quartz veins and stibnite-bearing exposures in weathered and altered intrusive rocks. Channel sampling gives more structured information than isolated selective rock chips, but remains a surface method. Infinity Mining (ASX:IMI) reported a standout interval from trench TTD-002 comprising 4.9 metres grading 7.71% antimony and 0.48 grams per tonne gold. Within that channel, a 1.2-metre section returned 30.20% antimony and 0.46 grams per tonne gold. The results are channel lengths, not demonstrated true vein widths. The narrower interval makes a major contribution to the broader antimony result, so the composite should not be read as evidence of uniform grade across an extensive orebody. Additional samples returned varying combinations of the two metals.

Geological Interpretation and Its Limits

Mapping has identified quartz vein-hosted material as well as stibnite interpreted as hydrothermal replacement within intrusive rocks. These observations can help the exploration team consider multiple target styles, rather than searching only for narrow veins. Earlier soil geochemistry outlined a broader gold-antimony anomaly, but a soil footprint does not prove that mineralisation is continuous beneath it. Infinity Mining (ASX:IMI) has discussed broad geological similarities with the Sunday Creek system elsewhere in Victoria. That comparison is conceptual and does not establish comparable grade, scale or economics. These distinctions matter particularly when interpreting visually striking antimony assays.

Equivalent Grades and Metallurgical Uncertainty

Gold-equivalent numbers combine gold and antimony using assumed metal values and recoveries. They are calculations, not direct gold assays, and a high equivalent grade can arise mainly from antimony. For the Tanjil Dome headline material, the company indicates that antimony accounts for the dominant contribution. Infinity Mining (ASX:IMI) has not completed project-specific metallurgical test work to demonstrate achievable recoveries. Mineral processing can be sensitive to the form and distribution of antimony minerals, ore variability and concentrate specifications. Without recovery results and a defined deposit, economic conclusions would be premature. The present work provides targets for further investigation rather than a production case or a development forecast.

Drill Preparation and Risk Factors

The joint venture intends to combine channel assays with mapping, structural measurements and earlier soil results to improve drill targeting. Further trenching at Tanjil Dome and nearby Good Hope has also been proposed along accessible ground. Infinity Mining (ASX:IMI) is working on drill designs and work-plan submissions, although access and approvals remain prerequisites. The first drilling would need to assess true thickness, continuity and the relationship between veins and replacement-style mineralisation. Laboratory assays alone cannot answer those questions. Funding, seasonal field access and technical results will influence the next stage. Until drilling is completed, the project should be described as prospective surface mineralisation rather than a demonstrated resource.

Key Insights

Infinity Mining (ASX:IMI) has identified antimony-rich channel samples at Tanjil Dome, with geological mapping providing a framework for further exploration. The priority is to establish depth continuity and metallurgical behaviour. Neither the surface grades nor calculated gold-equivalent figures establish an economic deposit.
