- Killi Resources drilling finds large epithermal gold-copper system at the Kaa prospect
- First three diamond holes return maximum values of 5.9g/t gold, 40.8g/t silver and 3.7% copper
- Assays pending for remaining three holes, IP survey completed at Baloo prospect
Special Report: Drilling at the Kaa prospect within Killi Resources’ Mt Rawdon West project in Queensland has uncovered a large gold-copper mineralised system after returning significant results over 1km of strike.
The first three of six diamond holes completed at the prospect to date returned significant assays with maximum values of 5.9g/t gold, 40.8g/t silver and 3.7% copper, extending mineralisation beneath surface rock chips.
Rock chip sampling had previously reported maximum assay results of 238g/t gold, 585g/t silver, 2860ppm bismuth, 5.35% copper and 3.58% antimony.
Killi Resources (ASX:KLI) notes the intersection of up to 150m wide zones of mineralisation associated with shear zones and sulphide bearing quartz veins over 1km of strike indicates that a large epithermal system is present.
“We are excited by these initial developments in the first few drill holes ever at the project, which has intersected large zones of alteration with mineralised veins,” chief executive officer Kathryn Cutler said.
“These initial observations of strong alteration suggest we are in the middle of a large, epithermal system which has seen significant amounts of fluid through the prospect. The drill results and observations mimic the typical style and distribution of vein networks and alteration we would anticipate in an epithermal system.
“This reinforces what we have seen expressed at surface and that we are on track with our early-stage exploration to unlock a new system. Assays remain pending for three holes, which will provide further data to assist vectoring and the next phase of drilling.”
Kaa drilling
All three initial holes intersected wide zones up to 150m, of intense potassic, silica and sericite alteration, with quartz carbonate veining within the granodiorite.
Structures within these wide zones of alteration contained sulphide bearing quartz veins, with visible pyrite, chalcopyrite, malachite, azurite and arsenopyrite.
These zones are encouraging as they are indicative of significant movement of hydrothermal fluids and are often indicators of proximity to an epithermal copper-gold system.
KLI notes the veins and sulphide content increase with proximity to the main trend and towards the south-eastern end of the trend, a first vector point for future targeting to unlock Kaa as a new epithermal system.
Next steps
The company is now awaiting assays from the remaining three diamond holes at Kaa before it carries out a comprehensive review of the structural and geochemical information.
This data will be used to determined vectors, which will aid in finding targets to discover the source of the gold and copper mineralisation and inform the next phase of drilling at the prospect.
Separately, KLI has completed the induced polarisation survey over the copper-gold-molybdenum soil anomaly at Baloo.
