Askari on trail of potential Pilbara copper-silver porphyry

Askari Metals has revealed some tantalising high-grade copper-silver mineralisation in rock chip sampling at its Callawa project in Western Australia’s Pilbara region, jagging a top hit of 6.78 per cent copper with 2.34 grams per tonne silver.

The headline result is supported by a second sample that produced 4.35 per cent copper with 8.25g/t silver and a third offering of 2.02 per cent copper with 6.42g/t silver. There is also a fourth sample giving up a lower copper value at 1.85 per cent, but it has a surprising 11.1g/t silver hit.

Only trace gold was identified in the range of 11 parts per billion to 48ppb for the four samples, while molybdenum ran 1.3ppm to 5ppm across the suite. The results are somewhat comparable with two previous samples collected at the project, which gave up 9.35 per cent copper with 25.9g/t silver and 7.63 per cent copper with 15.7g/t silver.
