• Assays from rock chip samples returned high-grade copper and gold hits
  • The Mt Rawdon West project covers 305km2 of prospective Queensland tenure
  • Mt Rawdon sits just 8km from historic gold mine of same name
  • KLI confident of potentially large economic copper-gold discovery


Killi Resources has intercepted high-grade hits of up to 7.2% copper and 12.4 g/t gold at surface from rock chip samples from its Baloo prospect, part of the Mt Rawdon West project in Queensland.

The 305km2 project covers the intersection of the highly prospective Mt Rawdon gold corridor with the Mt Perry copper-gold corridor.

The Mt Rawdon gold mine, only 8km from Killi’s (ASX:KLI) tenement boundary, has produced 1.8 million ounces of gold to date, consistently producing 75,000-80,000oz annually.

At Mt Rawdon West, Killi believes there is “a significant discovery opportunity” for company making porphyry copper-gold systems.

This sampling program is the first modern exploration at Mt Rawdon West since historical mining ended in the early 1900’s.


Up to 7.2% copper and 12.4 g/t gold

The high-grade copper and gold rock chip results identified a 5.5km long by 2.5km wide copper-gold-silver corridor, referred to as the Baloo prospect.

Assays returned up to 7.2% copper and 12.4 g/t gold, with 12 of the 26 rock chip samples collected returning assays greater than 1% copper. Results included:

    • 7.2% copper and 27.2 g/t silver;
    • 4.2% copper, 1.16 g/t gold, 75.8 g/t silver, 1% lead and 0.3% zinc;
    • 4.5% copper, 0.09 g/t gold and 83.7 g/t silver;
    • 3.5% copper and 85.9 g/t silver;
    • 3.3% copper, 0.37 g/t gold and 31.1 g/t silver;
    • 2.4% copper, 0.48 g/t gold and 22.3 g/t silver;
    • 2% copper, 12.4 g/t gold and 65.6 g/t silver; and
    • 0.6% copper, 4.26 g/t gold and 32.9 g/t silver.

Notably, the copper mineralisation at surface commonly occurred as bornite across the corridor, which is a strong indicator mineral for proximity to intrusive-porphyry copper-gold systems.


Economic copper-gold potential

“This first program in the field has identified significant copper mineralisation at surface at multiple locations across the main target area,” Killi CEO Kathryn Cutler said.

“We previously had two target areas Wonbah and Baloo, however with these results we believe this is a much larger system than originally thought and will refer to the mineralised corridor as Baloo.

“The location of multiple old workings from the early 1900’s, had been recorded by the Queensland Government, however the commodity and mining specifics have not.

“The scale of the historical workings from the turn of the last century demonstrates there is a significant potential here for an economic copper-gold discovery.

“Since the early 1900’s, the region has not seen much exploration attention, except a few soil programs completed in the early 2000’s, which did not cover the main corridor, or historical workings, however, did highlight a copper-gold-molybdenum anomaly in the centre of the tenement.

“From the rocks, alteration, and visible mineralisation observed on the ground, we believe the Baloo area to be highly prospective for a porphyry copper gold system, with these rock chip results demonstrating we do have the grade needed.”


Soil sampling results pending

The results of the soil sampling program are expected in the next two months.

In the meantime, further evaluation of the field data in conjunction with the geochemical data is being conducted to further understand the intrusions and develop targets for follow-up works.

Geophysical data from site is also being re-evaluated to add further information to the project’s geological model.
