MacPhersons hits longest silver intersection at Nimbus
THE DRILL SERGEANT: Drilling of extensions to Lens Nos. 1, 2, 3, and 4, by MacPhersons Resources (ASX:MRP) at the company’s 100 per cent-owned Nimbus silver-zinc-gold project has demonstrated both silver oxide and silver sulphide mineralisation continues between the Nimbus Discovery and East Pits.
The Nimbus project is located 10 kilometres east of Kalgoorlie’s Super Pit gold mine.
Preliminary results from the latest drilling carried out at Nimbus have returned the longest high-grade intersection drilled to date at the project:
– 28 metres at 900 grams per tonne silver from 200m depth, including 17 metres at 1434 grams per tonne silver, 26.3 per cent zinc and 4.7 per cent lead from 205 metres.
These results included eight metre-intervals exceeding 1500 grams per tonne silver.

MacPhersons explained that super high-grade mineralisation is defined as zones exceeding 15,000gram-metres of silver grade, which it said occurs in Lens No. 1 at Nimbus.
Zones of 12,000 to 14,000gram-metres occur in Lens No. 2.
The recent intersection of 28m at 900g/t silver (25,208 gram-metres silver) is the first super high grade intersection outside of Lens No. 1 and shows that Lens No.3 has significant upside to further high grade lens extensions.
The drilling indicates an 80m down dip extension to the New Lens No. 3.
“The new high grade extension to Lens No. 3, is a step change in mineralisation intensity,” MacPhersons Resources managing director Morrie Goodz said in the company’s announcement to the Australian Securities Exchange.
“MRP see the continuing intersections between the Discovery and East Pits as supporting the model of a single merged super pit.”
The company outlined relevance of the new super high grade silver-zinc mineralisation in a second lens supports modelling of multiple lens targets existing at Nimbus.
This is first lens of this intensity of metal grade distribution, since the Discovery Lens No.1 was identified in 1990’s.
Ongoing drilling and geological modelling is establishing further zones that may host additional massive and breccia sulphide mineralisation.
The company said it was encouraged by the progressive results that continue to show the silver mineralisation extends between and beneath both pits.
