Infinity Mining has reported standout rock chip assays from its Hillside Project in Western Australia, revealing copper grades up to 9.4% and silver at 163 g/t over a 9km corridor. The results open the door for drilling in a historically underexplored area near Develop Global’s Sulphur Springs deposit.
- High-grade copper up to 9.4% and silver 163 g/t from surface samples
- 10 gossans identified along a 9km strike with VMS-style mineralisation
- Historical drilling limited and poorly oriented, leaving targets untested
- Next steps focus on drill approvals, heritage surveys, and contractor mobilisation
- Project located near Develop Global’s significant Sulphur Springs deposit
Surface Sampling Unveils Strong Copper and Silver Potential
Infinity Mining Limited (ASX:IMI) has revealed impressive assay results from its inaugural rock chip reconnaissance program at the Hillside Project in the Pilbara, Western Australia. Samples collected across a 9km strike corridor returned grades as high as 9.4% copper, 163 grams per tonne silver, and 0.7 grams per tonne gold, signalling significant base metal and precious metal mineralisation near surface.
The sampling targeted 10 gossans, oxidized, mineral-rich outcrops, that display characteristics typical of volcanogenic massive sulphide (VMS) deposits. These gossans, previously untested by systematic drilling, lie about 50 kilometres southwest of Develop Global’s Sulphur Springs deposit, a notable 17.4 million tonne resource with copper, lead, zinc, and silver credits.
Geological Setting and Historical Exploration Gaps
Located within the Archaean Coongan Greenstone Belt, Hillside shares geological affinities with the neighbouring Panorama greenstone belt, home to Develop Global’s Sulphur Springs and Kangaroo Caves VMS deposits. The area features complex shearing and a major north-south fault zone, with surface expressions of mineralisation including silicified caps and malachite-stained gossans.
Historical drilling at Hillside has been sparse and, according to Infinity, poorly oriented relative to the mineralised structures. Only three of the 10 identified gossans have been drilled, with previous programs unlikely to have effectively tested the zones at depth. This leaves a large portion of the mineralised corridor unquantified and ripe for systematic drill testing.
Next Steps: Drilling and Approvals in Focus
Following these encouraging surface results, Infinity plans to fast-track approvals for a drilling campaign aimed at defining the mineralisation’s extent and continuity. Key upcoming milestones include refining drill targets, completing heritage surveys with Traditional Owners, ensuring regulatory compliance with DEMIRS Programme of Work conditions, and securing drilling contractors and mobilisation schedules.
Infinity’s Executive Chairman Cameron Petricevic described the results as "compelling," emphasising the company’s high conviction in Hillside’s exploration potential. The company’s approach aligns with its broader Pilbara strategy, which was recently bolstered by the commencement of ground exploration activities and the appointment of experienced geologists familiar with the region’s geology.
Implications for Infinity and the Pilbara Copper Landscape
These findings add momentum to Infinity’s portfolio, which spans several promising regions across Australia. The proximity to Develop Global’s Sulphur Springs deposit underscores Hillside’s strategic location within a proven VMS district. However, the surface nature of the assays means that the true scale and economic viability of the mineralisation remain to be tested by drilling.
As the company moves towards systematic drilling, investors will be watching how Infinity navigates the regulatory and heritage processes critical to advancing exploration in the Pilbara. The results also invite comparison with peer activity in the region, where companies are increasingly focused on unlocking VMS and other base metal deposits amid rising demand for copper and silver.
Bottom Line?
Infinity Mining’s high-grade surface assays at Hillside set the stage for a pivotal drilling campaign that could reshape the company’s Pilbara prospects.
Questions in the middle?
- Will drilling confirm the continuity and scale of the high-grade mineralisation identified at surface?
- How will Infinity manage heritage and regulatory approvals to maintain exploration momentum?
- Could Hillside emerge as a significant new VMS deposit within the competitive Pilbara base metals landscape?
