A rock chip sampling program has identified broad new zones of copper mineralisation and pathfinder elements at True North Copper’s Mount Oxide project.

The company has released assay results from sampling at the Aquila and Ivena North prospects at Mount Oxide, 140km north of Mount Isa.

At Aquila, sampling has highlighted six zones of anomalous copper, cobalt and arsenic associated with multiple gossanous breccia structures up to 30m wide.

• Aquila B Trend: +180m long and +30m wide copper-cobalt-arsenic-silver within a 440m long fault breccia with visible copper oxide mineralisation. The trend includes rock chip channels returning 3.6m at 0.49 per cent copper with a peak assay of 0.94 per cent copper.
• Aquila A Trend: +20m long and up to 12m wide copper-arsenic-antimony anomalous zone within +210m strike of hematite altered hydrothermal breccias, returning up to 0.05 per cent copper and 12.7g/t silver and anomalous pathfinders.
• Aquila D Trend: +100m long and up to 4m wide copper-cobalt trend associated with a historical prospecting pit with strong copper oxide mineralisation, and a peak assay of 0.87 per cent copper.

At Ivena North, sampling has identified copper-cobalt-arsenic trends within two geochemically anomalous zones from multiple gossanous breccia structures that are up to 25m wide.

• Ivena North A Trend – +130m long and up to 15m wide copper-cobalt-arsenic trend within a +580m strike of hydrothermal breccia and gossans that returned assays up to 1.38 per cent copper and anomalous arsenic (+/- Ag-Sb-Bi-Mo).

True North said rock chip results would be integrated with ongoing mapping and results from a
Queensland Government-funded MIMDAS IP and MT survey which is underway along the Dorman Fault Mineral System.

“Our exploration team has been working hard to systematically map and sample the +10km Dorman fault trend at Mount Oxide,” True North Copper managing director Bevan Jones said.

“Multiple gossans have been identified, and rock chip results from the gossans are revealing large areas of wider and stronger mineralisation on which to focus our future exploration work, including the ongoing MIMDAS geophysical survey.

“We are also remobilising the on-ground team to systematically collect additional rock chip samples over the newly discovered Black Marlin and Rhea structures.

“Further geophysical results are filtering through, and updates will be released soon.

“We are potentially building a significant district at Mount Oxide with multiple high-priority targets which have never been drilled. Our next steps include prioritisation of these targets, designing and planning upcoming drill programs, and securing the necessary permits for on-ground access.”
