High-Grade Antimony and Gold Confirmed at Tanjil Dome, Victoria
Infinity Mining Limited (ASX:IMI) has unveiled compelling exploration results from its Tanjil Dome project in Victoria, where rock chip assays returned extraordinary grades of up to 48.7% antimony and 1.35 grams per tonne (g/t) gold. These samples, taken from quartz veins, also showed a combined gold equivalent (AuEq) value of 167.1, highlighting the prospect's significant potential.
Complementing these assays, soil sampling delineated a coherent antimony-arsenic anomaly extending over at least 500 metres, with portable XRF readings peaking at 751 parts per million (ppm) antimony and 791 ppm arsenic. The geological setting, characterised by stibnite veining, gold-bearing quartz veins, brecciation, and altered dyke material, points to a structurally controlled hydrothermal system that remains open for further exploration. Laboratory assays are still pending, but the early-stage results already mark Tanjil Dome as a promising target for intrusion-related and orogenic gold-antimony mineralisation.
Pilbara’s Hillside Project Yields Encouraging Base Metal and Silver Assays
Meanwhile, in Western Australia’s Pilbara region, Infinity’s reconnaissance rock chip program at the Hillside project has delivered high-grade base metal and silver results. Among 47 samples collected, assays peaked at 9.4% copper, 163 g/t silver, 0.7 g/t gold, and 0.7% zinc. The project hosts a 9-kilometre trend featuring 10 outcropping gossans consistent with volcanogenic massive sulphide (VMS) mineralisation, including two major surface zones exceeding 100 metres in length and 30 metres in width.
Only three of these gossans have been previously drilled, and historical holes may not have effectively tested the new targets at depth due to orientation and structural complexities. Infinity is now advancing drill target ranking and regulatory approvals, with plans to commence drilling to assess the continuity and tonnage of mineralisation. The Hillside project lies approximately 50 kilometres from Develop Global’s Sulphur Springs deposit, which boasts a 17.4 million tonne resource grading 1.0% copper and significant zinc, lead, and silver credits, underscoring the regional prospectivity.
Cangai Copper Resource Under Review Amid Promising Metallurgical Tests
In New South Wales, Infinity’s Cangai Project is undergoing a critical reassessment after an independent review identified issues with the historical JORC 2012 Mineral Resource Estimate, including block model validation and cut-off grade applications that undermine the reported grades and tonnage. The company is appointing a mineral resource consultant to prepare a revised estimate, cautioning investors against relying on the historical figures until the update is completed.
Despite these uncertainties, metallurgical test work conducted by Orivium Global at the University of Sydney has demonstrated copper extraction rates approaching 100% from historical smelter waste stockpiles under laboratory conditions. While these results are preliminary and require further validation through engineering studies and economic evaluation, they bolster the case for commercial processing of Cangai’s slag dumps and e-waste feedstock under the expanded cooperation with Orivium.
Corporate Moves and Financial Position
Infinity strengthened its board with the appointment of Steven Wood, a seasoned geologist with over three decades of experience including work at Develop Global’s Sulphur Springs project. Financially, the company reported a cash balance of $370,739 at quarter-end, supported by net proceeds of approximately $185,660 from the sale of Evergreen Lithium Limited shares. Exploration and corporate expenditures totaled around $166,000 for the quarter, with the company estimating at least two quarters of funding remaining, aided by its retained Evergreen Lithium shares valued at about $137,000.
With the company advancing multiple projects across three states and leveraging innovative processing partnerships, the coming months will be pivotal. Key catalysts include the release of the revised Cangai Mineral Resource Estimate, assay results from upcoming drilling at Hillside, and further assay data from Tanjil Dome’s ongoing exploration.
Bottom Line?
Infinity’s high-grade assays and promising metallurgical results set the stage for critical drilling and resource updates that will clarify the value of its Victorian and Pilbara projects.
Questions in the middle?
- Will the revised Cangai Mineral Resource Estimate materially alter the project’s valuation and development plans?
- Can drilling at Hillside confirm the extent and continuity of the high-grade copper-silver mineralisation indicated by rock chips?
- How might Orivium’s e-waste processing technology impact the economics of Infinity’s Cangai operations?
