Killi Resources Limited (ASX: KLI) has commenced reverse circulation drilling at the Rocky prospect within the Ravenswood North Au-Cu Project in the Charters- Towers region of northern Queensland.
During the 2022 field season, Killi identified a 1.5 sq. km gold-silver-copper soil anomaly supported by surface rock chip samples returning 173g/t Ag & 0.55% Cu, 56.3g/t Ag and 0.43% Cu, and 224g/t Ag and 0.28% Cu.
This geochemical anomaly is indicative of large-scale intrusion-related gold deposits similar to those within the district and in close proximity to the project, such as Mt Leyshon (3.9M oz Au and 2.4M oz Ag produced), Mt Wright (1.5M oz Au produced) and Ravenswood Gold Mine (3.5M oz Au produced).
This drill programme will be the first holes to test this anomaly and comprise approximately 2,000m.
Rocky has proved to be a robust geochemical target that the exploration team has developed this year, and it just keeps delivering,” Killi CEO, Kathryn Cutler, said.
“It is by far the best-looking geochemical anomaly I have drilled, so we have been looking forward to getting the rig out there and completing the first holes into the target. All approvals have been received and we are thankful to all our stakeholders for helping us achieve this milestone.’
Rocky Prospect
The drill campaign will be the first drill holes into the area and is planned to cover the prospect on wide 400m spaced lines, with 10 initial RC holes to be completed to a depth of 150 to 200m.
The company has completed two soil programs at the Rocky prospect this year, which was following up two anomalous rock chip samples completed by previous explorers of 17g/t Au with 5g/t Ag and 16.19g/t Au with 7.16g/t Ag.
A soil programme was completed over the Rocky rock chips on a 100 x 100m grid to cover the interpreted intrusive unit identified during the target generation process. The results outlined a potential alteration system anomalous in gold, silver, copper, bismuth, molybdenum, and tellurium, similar in geochemical signature to intrusion-related gold systems of the Charter Towers province.
An additional geochemical program was then undertaken infilling and extending the soil grid, and surface rock chip samples were also collected and analysed. Surface rock chips returned values of; 173g/t Ag & 0.55% Cu, 56.3g/t Ag & 0.43% Cu, and 224g/t Ag & 0.28% Cu. The results now extend the system 4km along strike, south-west to north-east, with a 1.5 sq. km gold-silver-copper-bismuth-selenium- tellurium-thallium-indium core anomaly in the centre. This core is surrounded by elevated lead-antimony- arsenic levels proximally, and distal to that there is elevated copper and molybdenum. Within the core anomaly there are three high tenor gold anomalies with >200 x background values for gold.
The programme will cover the high-tenor gold and silver anomalies, with results anticipated in the new year.
