MacPhersons confirms new Silver-VHMS at Nimbus

/in /by

THE DRILL SERGEANT: Drilling undertaken by MacPhersons Resources on the company’s 100 per cent-owned Nimbus project, located near Kalgoorlie continues to deliver the goods with results under the East Pit and along strike of the Discovery Pit continuing to extend silver,-zinc-lead sulphide mineralisation lenses.

Drilling carried out to the east of the Discovery Pit returned preliminary assays extending its strike extension of VHMS zone including:

–    36.2 metres at 60 grams per tonne silver and 3.7 per cent zinc, including 6 metres at 184 grams per tonne silver and 9.1 per cent zinc; and

–    14.0m at 34g/t silver, 0.71g/t gold and 1.4 per cent zinc from 213.6m downhole depth.

Recent drilling of the East Pit floor has resulted in the completion of four holes with one currently underway.

All have demonstrated zones of VHMS mineralisation starting immediately in the pit floor and continuing to depths exceeding 200m below.

MacPhersons said the latest three of the completed holes have intersected a new VHMS zone from 140m to 210m downhole depth, which the company considers to indicate the presence of another stacked shoot under the East Pit.

Surface projections place the outcrop in a position with very little historical exploration, an area which the company said will be part of its focus with a new oxide silver drilling program.

MacPhersons conducted handheld XRF analyses on this zone that demonstrated sulphides to be enriched in silver-zinc-lead sulphides with grade ranges being 500 to 3600g/t silver, 6 to 32 per cent zinc and 1 to 8 per cent lead.

The company indicated that XRF analyses it has carried out on previous Nimbus massive sulphides are consistent with laboratory assays to date and that results from these drillholes are showing continuity in both sulphide mineralisation and silver-zinc-lead-gold content.

“These silver-zinc-lead mineralisation intersections extend known historical information to the east and continue to be repeated at depth (showing the zone to remain open at depth),” MacPhersons Resources said in its ASX announcement.

“These intersections are not included in the current resource classification.

“The Directors are pleased with the additional silver-rich VHMS zone and the extension of mineralisation to the south and east of the Discovery Pit and depth extensions beneath the East Pit.”

silver-zinc project.
