Impact Minerals Limited (ASX:IPT) has made another very high grade discovery at the recently named Dora East Prospect, which is part of the company's Broken Hill project.
The importance of the discovery is that it is adjacent to the Red Hill prospect, which contains platinum, palladium, gold, copper and silver, along with the rare rhodium, iridium, osmium and ruthenium.
Impact has now shown that Red Hill, and the Dora East Prospects, contain robust widths and grades of 12 different metals.
This is unprecedented in the Broken Hill region and indicates the highly unusual and very prospective nature of this part of Impact’s project area.
The Dora East and Red Hill Prospects lie within E7390. Impact owns 80% of the rights to Broken Hill style mineralisation on this licence in joint venture with Silver City Minerals (ASX:SCI).
The style of mineralisation is distinct from the platinum-copper-nickel mineralisation associated with ultramafic rocks that has been the focus of Impact’s work at the project and for which Impact owns 100% of the rights.
Drilling highlights at Dora East Prospect
New assays for Hole RHD020 completed late in 2015 delivered:
- 7 metres at 7% zinc, 1.1% lead and 20.7 g/t silver from 131 metres, including 1.6 metres at 22.0% zinc, 3.6% lead and 66.7 g/t silver.
In addition, a zone of good copper and silver grades has been identified that returned:
- 0.7 metres at 2.4% copper and 22.5 g/t silver from 109.5 metres.
Three drill holes have now returned significant intercepts of zinc-silver-lead mineralisation with many hundreds of metres of untested strike potential and new targets identified.
This is now Impact’s third hole at the Dora East Prospect to return robust widths and grades of so-called “Broken Hill-style mineralisation.”
The mineralisation comprises zinc, lead, silver and copper hosted by “Lode Rocks” similar to those that surround, and are integral to, the nearby world class Broken Hill 300 million tonne zinc-lead-silver deposit.
Next steps at Broken Hill
Assays are currently pending from follow-up mapping and soil and rock chip sampling programs at the Little Darling Creek and Platinum Springs Prospects.
All of this data will be reviewed and synthesised to design follow up work programs including drilling at Red Hill, Dora East, Little Darling and Platinum Springs.
