Diamond drilling across Impact Minerals’ Hopetoun JV is underway, testing alteration zones previously identified in RC drilling at the Top Knotch copper-gold target.

A second target, Silverstar, will also be tested in this program with statutory approvals in progress for another four drill ready targets at the Hopetoun project, around 25km south of the Ravensthorpe mining centre in Western Australia.

Impact Minerals (ASX:IPT) says alteration minerals (K-feldspar and biotite), copper values (up to 250 ppm as measured with a handheld XRF instrument) and sulphide intensity all increase down hole at the Top Knotch target, with mineralisation open at depth and along trend.

Originally identified in proprietary geophysical data and ionic leach soil geochemistry, Top Knotch could not be tested further due to extremely difficult drilling conditions for the RC drill rig in the transported overburden.

IPT says diamond drilling will therefore be able to penetrate this cover sequence.


The Hopetoun project is one of four recently announced joint venture projects where Impact is earning an 80% interest.

The project contains six drill ready targets of which two, Top Knotch and Silverstar, are fully permitted for drill testing.

Silverstar will also be tested in this drill programme with statutory approvals being sought for the other targets, likely to be drilled later in the year.
