Platina Resources (ASX:PGM) has something to write home about after intersecting its highest ever zinc grades at the Blue Moon zinc-copper-gold project in California.

And it is not hard to see why when the company has a 1.71m interval grading 51.9 per cent zinc, 1.49 per cent copper, 0.85 grams per tonne (g/t) gold and 31.9g/t silver from a depth of 414.65m.

That hit came from within a broader zone of 3.05m at 49.6 per cent zinc, 1.39 per cent copper, 0.91g/t gold and 30g/t silver.

The same hole also intersected a deeper zone of 10.96m at 3.11 per cent zinc and 0.47 per cent copper from a depth of 450.37m, including a higher grade interval of 2.08m at 4.22 per cent zinc.

Platina noted that these intervals were about 50m higher than the high-grade mineralisation intersected in 2018 while extending the zone of high-grade mineralisation within the main mineralised horizon.

The recently completed drilling program is expected to increase the size of the existing inferred resource and convert it to the higher confidence indicated and measured categories.


Empire Resources’ (ASX:ERL) aircore drilling has confirmed multiple targets and identified a new 3.5km copper-gold horizon at the Yuinmery project in Western Australia.

Results from the reconnaissance drilling include 2m at 10,369 parts per million (ppm), or a little over 1 per cent, copper just 4m from the surface.

This was from within a broader interval of 12m at 6,619ppm copper from surface, 17m at 3,766ppm copper and 101 parts per billion (ppb) gold from surface and 12m at 4,022ppm copper and 185ppb gold from 19m.

The company said the results indicated the project’s potential to host multiple copper-gold deposits and that follow-up reverse circulation drilling would be warranted to test the identified anomalism.
