Moonlight copper hits add muscle to QLD gold story

Moonlight Resources has put a modern stamp on a 160-year-old copper field, with its first drilling at the Peak Downs prospect in central Queensland returning broad, shallow mineralisation and strengthening the case for a potential resource. Peak Downs forms part of the company’s 100 per cent-owned Clermont project.

The 56-hole, 2988m reverse circulation program twinned selected old holes and filled gaps between previous drill positions. Moonlight says the results suggest strong continuity, led by 22m grading 1.26 per cent copper from surface, including 8m at 2.41 per cent from 2m.

Other hits ran 14m at 1.5 per cent copper from 52m, with 4m at 3.57 per cent from 54m and 6m at 2.64 per cent from 52m, containing 2m at a punchy 6.26 per cent from 54m. From surface, 12m at 1.42 per cent contained 2m at 3.03 per cent from 4m, while another 12-metre interval graded 1.21 per cent and featured 4m at 1.99 per cent from 6m. A wider 28-metre intercept at 0.7 per cent included 2m at 2.73 per cent from 24m.

An intriguing cobalt kicker also emerged, with 14m at 1.5 per cent copper and 511 parts per million (ppm) cobalt from 52m. Moonlight says more work is required to establish its distribution, mineralogical association and metallurgical significance.

Peak Downs brings serious history to Moonlight’s 268-square-kilometre Clermont project in the Anakie Inlier’s copper and gold country. Records show approximately 100,000 tonnes of near-surface secondary ore averaging a hefty 17 per cent copper were mined between 1862 and 1877 from a lode system interpreted to run roughly 2.5km.

The story did not end there. Later exploration drilling returned 39m at 1.11 per cent copper and 20m at 1.49 per cent, suggesting the field still had more cards to play.

Recognising Peak Downs was underexplored using modern techniques, Moonlight designed its recent campaign to test whether the old field had more running room. Eighteen holes stopped after running into historical underground voids, helping to map the old workings for future resource modelling.

Moonlight Resources managing director Greg Starr said: “The results from our maiden Peak Downs drilling provide the modern confirmation of copper mineralisation across a system previously defined largely by historical drilling and old mining records.”

With all assays now in the bag, Moonlight says it plans to combine the new results with inherited drilling and mining data to refine its geological model. Targeted diamond drilling is next cab off the rank to tighten geological and structural control and provide representative core for metallurgical assessment.

The next round of testwork will put Moonlight’s copper through its paces, testing recoveries, mineralogy and the key ingredients needed for potential heap-leach processing as the company sizes up whether solvent extraction-electrowinning could provide a viable development pathway.
