Infinity Mining Returns High-Grade Copper-Silver Assays in Maiden Sampling at Hillside Project

Infinity Mining (ASX: IMI) has reported high-grade assays with peak values of 9.4% copper, 163 grams per tonne silver, 0.7g/t gold, and 0.7g/t zinc from maiden sampling at its Hillside copper-silver-gold project in Western Australia’s Pilbara region.

The rock-chip reconnaissance program collected 47 samples from 10 outcropping gossans to the south-west of Develop Global’s (AWX: DVP) Sulphur Springs discovery that hosts a resource of 17.4 million tonnes grading 1% copper, 0.3% lead, 5.8% zinc, and 21.8g/t silver.

The gossans feature two major surface-observed zones over 100 metres in length and 30m in width that have never been subject to proper drill testing.

Infinity believes these are consistent with volcanogenic massive sulphide (VMS)-style multi-element alteration system.

VMS Mineralisation Framework

The 36 samples taken targeted exposed gossanous horizons distributed along a continuous 9km strike corridor, where field observations indicated a VMS mineralisation framework characterised by a distinct silicified cap, oxidised sulfide lenses, and underlying footwall stringer zones.

A total of 23 samples returned anomalous values for copper, zinc, silver, and gold mineralisation, while surface expressions of the mapped gossans exhibited high morphologic variability in strike lengths ranging from 20m to more than 100m, with structural widths up to 30m.

Structural mapping within these systems indicated a steep, moderate-to-sub-vertical westerly dip.

Across the northern portion of the trend, the systems were found to be partially obscured by transportive alluvium, leaving only the silicified outcrops, with Infinity confirming that drill testing would be required to accurately define the true extent and depth continuity of these zones.

‘Significant Potential’

Chair Cameron Petricevic said Infinity—whose current market capitalisation is less than $4.5 million—would now seek approvals for the start of drilling at Hillside.

“These are compelling results that show Hillside has significant potential mineralisation,” he said.

“In light of these assays, we considers Hillside to be a high-conviction exploration potential and we are moving quickly to secure approvals for a drilling campaign.”

Infinity’s next steps in advancing the project will include drill target refinement and matrix design, heritage survey engagement with the relevant Traditional Owners, a comprehensive regulatory compliance review to ensure full alignment with existing approvals, procurement of the preferred drilling contractor, and finalisation of the field mobilisation schedule.
