Drilling Commences at Commonwealth, NSW
The drill programme will test a significant number of targets along trend and at depth from the high grade mineralisation discovered in the Commonwealth-Silica Hill area as well as new targets in the immediate surrounding areas. Further details will be provided as the programme progresses.
About the Commonwealth Project
The Commonwealth Project forms part of Impact's extensive 100% owned land holding of 1,000 sq km in the Lachlan Fold belt, home to numerous gold and copper mines including the giant Cadia deposit near Orange (40 million ounces of gold and 12 million tonnes of copper).
At Silica Hill significant gold and silver mineralisation has been intersected in six drill holes and covers an area of 200 metres by 100 metres down to a depth of 120 metres below surface and with an average true thickness of at least between 50 metres and 70 metres. The mineralisation is open in all directions including up dip (see Figure 1 in the link below).
Four drill holes out of the six have also returned gram-times-metre intercepts of more than 100 gram.metres. These are robust and significant results for potential bulk mining and indicate the potential to significantly increase the resources at the Commonwealth Project, which currently stand at 720,000 tonnes at 2.8 g/t gold, 48 g/t silver, 1.5% zinc and 0.6% lead (see announcement 19 February 2015).
In detail, these thick widths of mineralisation actually comprise numerous narrow veins and vein stockworks of high grade gold and very high grade silver hosted by the Silica Hill rhyolite that contain lower grade disseminated gold and silver.
For example, Hole CMIPT046 returned an intercept of
41 metres at 2 g/t and 176 g/t silver from 61 metres including 30 individual assays of varying widths of between 2 g/t and 24 g/t gold and 12 individual assays with more than 500 g/t silver including
1 metre at 12.2 g/t gold and 680 g/t silver including 0.3 metres at 23 g/t gold and 1,110 g/t silver;
1 metre at 5.3 g/t gold and 924 g/t silver;
1.7 metres at 3.8 g/t gold and 1,176 g/t silver; and
0.7 metres at 1.5 g/t gold and 855 g/t silver.
(see announcements dated 5th December 2016 and 22nd February 2017).
Impact's work has shown that the mineralisation at Commonwealth-Silica Hill is part of a gold-rich VMS system (volcanogenic massive sulphide) and has strong similarities to the Eskay Creek Mine in Canada (>4 million ounces of gold and 150 million ounces of silver).
