Killi Resources Ltd (ASX:KLI) has delivered polymetallic hits anomalous for gold, silver, copper and lead in a surface rock chip and soil sampling program at Rocky Prospect within the Ravenswood North Project in Queensland.
Surface rock chip and soil results extend the Rocky geochemical footprint to four kilometres along strike with strong results including:
- 5.27 g/t gold, 13.05 g/t silver and 0.11% copper;
- 224 g/t silver and 0.28% copper;
- 173 g/t silver and 0.55% copper; and
- 56.3 g/t silver, 0.43% copper and 0.19% lead.
Notably, the results indicate a rich gold-silver core to the 1.5 square kilometres system with corresponding copper, selenium, tellurium and indium enrichment.
Proximal to the core is strong lead-antimony and zinc enrichment, followed by a distal system elevated in silver, copper, lead, antimony and molybdenum.
This geochemical fingerprint is not only indicative of large-scale intrusion-related gold deposits around the world but is also similar to that of district systems within close proximity to the project.
Moving forward, heritage surveys are scheduled for the end of this month, to enable the company to drill test the surface gold-silver-copper anomaly generated from field programs this year.
Large gold-silver-copper system
Killi CEO Kathryn Cutler said: “Rocky is proving to be a large gold-silver-copper system, with these high-grade surface results extending the footprint of the prospect to 4 kilometres along strike.
“We are working through our approvals currently with a heritage survey scheduled for November 2022 to enable us to get on the ground and drill test Rocky.”
Field mapping and rock chip sampling.
Geochemical results
Killi completed a 240-sample soil program in August at the Rocky Prospect, infilling and extending the geochemical grid to the northeast and southwest.
Highly anomalous gold results were returned with the best results of 1,160ppb gold, 629ppb gold and 483ppb gold, which along with other samples has generated a third gold anomaly at the prospect.
In addition to the new gold anomaly, the footprint for other elements such as copper, molybdenum, silver and bismuth has also been extended northeast and southwest a further 1 kilometre in each direction.
Three field trips have been completed this year to generate these results and targets, and the company now plans to drill test the prospect as soon as approvals are received.
Rock chip sampling
Killi completed field mapping and ground truthing of rock chip samples over the prospect in October.
Mapping of lithologies and structures associated with the mineralisation will aid in determining the ideal direction to drill test the anomaly.
Geological observations identified mineralisation to be hosted in magnetic biotite-granodiorite.
Forward plan
Modelling of the VTEM results at Rocky is being completed with the results to assist with drill program planning and design.
At Ravenswood North, results from the soil and rock chip sampling from West Branch, Hawkeye and Success West prospects will be reported in the coming weeks.
Results also remain pending for 10,000 metres of aircore/RC drilling and 890 metres of diamond drilling at the West Tanami Project in WA's Kimberley region.
