PT: Silver Swan Extends Depth Of Known Copper Mineralisation
Large, new copper intersections at Silver Swan Group Ltd’s (ASX: SWN) Austin VMS copper discovery in Western Australia have extended the deposit to below 300 m and confirmed the potential for the discovery to continue to be expanded.
The latest drilling shows the ore body remains open at depth and retains similar, multi-metal characteristics to earlier drilling. It also confirms that Austin has the potential to develop into a significant deposit, said Silver Swan managing director Dr Susan Vearncombe.
“The latest assay results affirm our discovery of significant volcanogenic copper-zinc mineralisation. Our deepest hole to date, 09ATRCD 024, demonstrates excellent continuity of mineralisation at depth,” she said.
“As we advance our drilling program we expect that further assays will add to the current dimensions and continuity of the Austin deposit.”
Austin, about 55km south of the town of Meekatharra, is part of the Quinns project 100% owned by Silver Swan Group in the Murchison belt of Western Australia.
A total of 10 holes have been drilled recently into the Austin Cu-Zn-Ag-Au mineralisation, with assays received for a total of six holes. These holes comprise diamond, reverse circulation and RC precollars with diamond tails.
The Austin ore body is now known to be massive and continuous down to a vertical depth of over 300m as indicated by drillhole 09ATRCD024. Mineralisation remains open at depth and along mineralized limbs extending south-southeast and northwest.
High grade copper, zinc, silver and gold mineralisation were encountered in six drill holes. The mineralisation discovered at Austin begins just 50m vertical from the surface and is almost completely comprised of primary sulphides.
Some of the outstanding drill hole results include the following:
Drillhole 09ATRC027 intersected 50m @ 1.5% copper from a depth of 64m downhole, that includes high-grade intervals of 10m @ 3.9% Cu, 6m @ 3.5% Cu, 10m @ 15.7g/t Ag, 6m @ 11g/t Ag.
Drillhole 09ATRC034 intersected 87m @ 1.5% Cu from 73m downhole with a high-grade interval of 24m @ 2.5% Cu, 16m @ 13.1% Zn, 13m @ 7.9g/t Ag, 10m @ 13.8g/t Ag and 9m @ 0.96g/t Au.
Drillhole 09ATRCD024 intersected 19m @ 1.2% Cu from 316m downhole including 5m @ 1.8% Cu, 6m @ 7.3% Zn, 19m @ 3.9g/t Ag, 0.24g/t Au. This hole confirms down plunge continuity to >300m.
