Chase Mining observes further massive sulphides in final diamond hole of Alotta campaign

The diamond rig is being mobilised to the nearby Lorraine Mine Gold Project to begin drilling deep holes to confirm previous high-grade gold sampling.

Chase Mining Corporation Ltd - Chase Mining observes further massive sulphides in final diamond hole of Alotta campaign
Core from hole ZA-20-05 showing massive chalcopyrite and massive sulphide

Chase Mining Corporation Ltd (ASX:CML) has received further encouraging results from a diamond drilling program at the Alotta Copper-Palladium-Platinum-Nickel Project in Canada with massive sulphides again intersected.

The final hole in the 5-hole program intersected visual massive chalcopyrite and a massive and net textured sulphide zone from 57.8 to 62.3 metres and massive sulphide from 81.55 to 86.7 metres downhole.

Three zones at depth

While hole ZA-20-05 has yet to be logged, photographed, cut and sampled in detail, a summary quick first-pass whole core log visually confirmed three zones of mineralisation at depth.

These include massive and disseminated mineralisation:

  • A 4.5-metre sulphide zone with 0.2 metres of massive chalcopyrite from 57.8 metres and massive sulphide and net textured sulphides in feldspar porphyry and gabbro to 62.3 metres downhole;
  • Mineralised gabbro with disseminated sulphides from 76.5 to 78.0 metres downhole; and,
  • Typical (Alotta) fine-grained massive pyrrhotite from 81.85 to 86.7 metres downhole.

Rig moving to Lorraine

This hole competes the program at Alotta and the drill rig is being mobilised to the Lorraine Mine Gold Project to begin drilling deep holes to confirm previous high-grade gold sampling at the base of the mine.

The diamond drilling at Alotta in Quebec was designed to test around 2019 hole ZA-19-05 and to evaluate the importance of the assays returned from it, namely:

  • A 4.1-metre zone of mineralisation hosted in feldspar porphyry from 55.3 metres downhole assaying 5.3% copper, 4.9 g/t palladium, 0.9 g/t platinum, 0.26% nickel and 12 g/t silver;
  • A porphyry hosted ‘bonanza grade’ 0.5-metre zone of chalcopyrite-pyrrhotite massive sulphide from 55.3 metres assaying 22% copper, 34 g/t palladium, 3.5 g/t platinum and 0.78% nickel, 1.4% zinc, 65 g/t silver; and,
  • A 10-metre massive sulphide zone assaying 2.37% nickel and 2.38% copper from 59.0 metres.

Hole ZA-20-05 was drilled to test the west strike extension of this 2019 hole and an undercut of 2020 hole ZA-20-04.

Awaiting assays

Cutting of all the mineralised core from the Alotta program is underway and samples will be then submitted for analyses.

Presently the expected turnaround is 5 to 6-weeks with assays due in August.

The company has made the decision to await final assay results and add the results to the current internal model before deciding on where further drill holes at Alotta will be located.
