Infinity Mining Limited (ASX:IMI) has reported gold and antimony assay results from an initial channel sampling program at its Tanjil Dome prospect, with trench TTD-002 returning 4.9 m at 0.48 g/t Au and 7.71% Sb (26.92 g/t AuEq), including 1.2 m at 0.46 g/t Au and 30.20% Sb (104.06 g/t AuEq), with drill planning now underway.

Key Points

  • TTD-002 returned 4.9 m at 26.92 g/t AuEq, including 1.2 m at 104.06 g/t AuEq from 30.20% Sb
  • Results come from 10 trenches comprising 62 channel intervals over 58.1 m, testing quartz veins and stibnite within highly weathered intrusive rocks
  • Exploration at Tanjil Dome is conducted in joint venture with Mining One Consultants
  • Geology shares broad similarities with the Sunday Creek gold-antimony deposit approximately 100 km away
  • A maiden drill program is being targeted, with true widths and continuity at depth unconfirmed

Tanjil Dome Channel Sampling Results

The initial channel sampling program tested limited exposures within a broader approximately 1 km gold and antimony soil anomaly. Eight channels are clustered in the main trench sampling area, with two located approximately 200 m to the north. Additional significant intervals include TTD-001 returning 1.6 m at 0.46 g/t Au and 2.23% Sb (8.11 g/t AuEq), including 0.6 m at 0.47 g/t Au and 5.44% Sb (19.13 g/t AuEq); TTD-006 returning 5.0 m at 1.30 g/t Au and 0.02% Sb (1.37 g/t AuEq); and TTD-008 returning 0.6 m at 1.22 g/t Au and 3.69% Sb (13.89 g/t AuEq). Samples were submitted to On Site Laboratory Services, Bendigo. No top cut has been applied to the composites.

Geological Observations and Two Mineralisation Styles

Geological mapping at Tanjil Dome identified at least three discrete quartz-vein exposures within highly weathered, altered dyke rock, with significant stibnite hydrothermal replacement mineralisation also recorded. Local observations suggest broadly north–south strikes and steep dips, though correlation between exposures remains provisional. Mining One Geology Manager Stuart Hutchin noted two distinct styles of antimony mineralisation: quartz vein-hosted mineralisation and disseminated to massive stibnite interpreted to be associated with hydrothermal replacement within intrusive units. Geological logs distinguish hornblende diorite, fine-grained mafic dyke, weathered and altered dyke, and sedimentary rocks at dyke contacts. Channels were backfilled in accordance with Low Impact Exploration program requirements.

AuEq Calculation Basis and Next Steps

The AuEq calculation uses gold at US$4,000/oz and antimony at US$50/kg, with assumed recoveries of 85% for gold and 75% for antimony, consistent with the basis disclosed in prior company releases dated 27 July and 14 September 2026. Antimony contributes approximately 98% of the AuEq for the TTD-002 4.9 m composite, and approximately 96% of the length-weighted antimony total for that interval is attributable to the included 1.2 m sub-interval. No project-specific metallurgical testwork has been completed and actual recoveries may differ materially. The company stated results will guide further trench mapping and targeting for a maiden drill program. Infinity Mining Chairman Cameron Petricevic said the initial trenching has tested only a small part of the broader soil anomaly.
