Infinity Mining will ramp up its search for a joint venture partner at its Hillside project, 50km south of Marble Bar in Western Australia, after unveiling new nickel assays with headline hits of 135m at 2189 parts per million from 64m and 95m at 2197ppm from 254m.

Other significant results revealed today include 107m at 1727ppm from 235m, 52m at 1761ppm from surface and 16m at 2150ppm from 123m. Four of the nine reverse-circulation (RC) holes from the program contained assays greater than 1000ppm nickel across 24 zones and four of the zones returned a nickel-chromium ratio of greater than 1.

The company’s drilling effort totalled 2278m to target concealed conductive anomalies, which it believes may represent buried sulphide mineralisation, based on a helicopter-borne electromagnetic survey it acquired in 2018. The roughly north-south-trending electromagnetically anomalous zone cuts through the centre of the Hillside project, which comprises four tenements covering about 397 square kilometres.

This project is substantial in scale and encompasses a wide array of mineral targets. This latest survey has unveiled an impressive 125 additional anomalies that warrant thorough review. These results are encouraging, but Infinity will need to identify a venture party to further explore the potential for this region. Infinity Mining chief executive officer Joe Groot

The Hillside area boasts an attractive commodity mix of base metals with gold and lithium prospectivity, in addition to a copper-hosted volcanic massive sulphide project similar to Develop Resources’ Sulphur Springs operation, which sits about 70km to the north-west.

Sulphur Springs shows typical volcanogenic massive sulphide morphology, with a copper-zinc-rich massive sulphide lens underlain by a copper-rich stringer zone. Its resource is a significant 17.4 million tonnes at 5.8 per cent zinc, 1 per cent copper and 21 grams per tonne silver.

Previous rock-chip sampling on Infinity’s Hillside ground identified a new prospect with similar chemical makeup, revealing anomalous results of up to 0.45 per cent copper, 0.12 per cent molybdenum, 0.68g/t gold and 14g/t of silver.

About 30km north-west of Hillside, Pirra Lithium has hit lithium at its Spear Hill project, which is aimed at following up on the historic tin mining in the area that carried on until the 1970s. Pirra mapping has identified a pegmatite dyke exposed for about 2.5km of strike, which has produced rock-chip assays going up to 2.75 per cent lithium oxide.

Follow-up drilling assays confirmed lithium-bearing pegmatites up to 250m down-dip going as high as 2m at 1.11 per cent lithium oxide.

Infinity is now keen to sign up a dance partner to add some financial steam to its plans to dive into the 125 electromagnetic anomalies that are begging for the drillbit.
