Infinity Mining (ASX:IMI) has reported ‘high-grade’ copper, silver, and gold assays from its maiden sampling program at the Hillside Project in Western Australia’s Pilbara region.
The company collected 47 rock chip samples across the project during late May and early June, with 36 samples targeting exposed gossanous horizons along a 9km strike corridor. Results include grades up to 9.4% copper (Cu), 163 grams per tonne silver (Ag), and 0.7g/t gold (Au) from 10 outcropping gossans located approximately 50km southwest of Develop Global’s (ASX:DVP) Sulphur Springs deposit.
“These are compelling results which show Hillside has significant potential mineralisation. In light of these assays, Infinity considers Hillside has a high-conviction exploration potential and we are moving quickly to secure approvals for a drilling campaign,” Infinity Chairman Cameron Petricevic says.
Of the 36 gossan samples submitted for analysis, 23 returned anomalous values with 18 identified as strongly anomalous. The highest copper grade of 9.4% came from sample TM10516, while the peak silver result of 163g/t was recorded from sample TM10549. Additional significant results include 8.7% Cu and 163g/t Ag from sample TM10549, and 5.30% Cu with 124g/t Ag from sample TM10548.
Field observations indicate a volcanogenic massive sulphide mineralisation framework characterised by silicified caps, oxidised sulphide lenses, and underlying footwall stringer zones. Surface expressions of the mapped gossans exhibit strike lengths ranging from 20m to over 100m, with structural widths up to 30m.
The Hillside Project comprises four exploration licences covering the Archaean Coongan Greenstone Belt, which shares similar stratigraphic units and structural features with the neighbouring Panorama greenstone belt. The Panorama belt hosts Develop Global’s Sulphur Springs deposit containing 17.4 million tonnes at 1.3% Cu, 4.2% zinc (Zn), and 17g/t Ag, along with the Kangaroo Caves volcanogenic massive sulphide deposit.
Historical drilling data reveals only three of the 10 identified surface gossans have been subject to prior drilling. Analysis of historical collar locations and drill hole orientations indicates the previous programs were poorly oriented and unlikely to have effectively tested the targets or intercepted mineralised zones at depth.
Infinity plans to progress drill target refinement and approvals ahead of its maiden drilling program.
