Visual Copper Mineralisation at Ilgarari Raises Questions on Resource Upside and Next Steps

Visual Confirmation of Copper Mineralisation

Lord Resources Limited (ASX – LRD) has reported a significant visual copper mineralisation interval of 20.2 metres in drillhole 25IRC006D at its Ilgarari Copper Project, located in Western Australia. The interval, observed between 158.5m and 178.7m depth, includes visible chalcocite and native copper, which are encouraging indicators of a potentially high-grade copper zone.

The presence of these copper minerals visually supports the company’s geological model, suggesting a supergene-enriched zone sitting above primary sulphide mineralisation. This discovery extends known mineralisation approximately 60 metres down-dip and 100 metres along strike from historic copper intercepts, reinforcing Ilgarari’s legacy as a copper-producing district.

Drilling Progress and Government Support

The current drilling program includes both reverse circulation (RC) and diamond drilling, with 11 RC holes completed and multiple diamond tails underway. Notably, two deep diamond drillholes; 25IRC007D and 25IRC009D; have intercepted primary mineralisation with up to 5% chalcopyrite, co-funded by the Western Australian Government’s Exploration Incentive Scheme (EIS), which provides 50% co-funding support. This partnership underscores the project’s strategic importance and reduces financial risk for Lord Resources.

While visual estimates provide an early indication of mineralisation, the company cautions that these are not substitutes for laboratory assays. Assay results from the current drilling campaign are expected in October 2025, which will provide definitive data on copper grades and mineral quality.

Project Context and Next Steps

Ilgarari sits within the Mesoproterozoic Bangemall Basin, a geological setting known for copper mineralisation associated with fault and shear zones near dolerite-shale contacts. Historically, the area has seen intermittent copper mining, with oxide mineralisation near surface and sulphide mineralisation at depth.

Lord Resources holds an earn-in agreement to acquire up to 80% of the sulphide mineral rights below 120 metres depth, with additional 100% applications pending. The company is currently evaluating options to extend the drill program based on ongoing results and plans to complete all core processing and sampling shortly.

Exploration Manager Georgina Clark highlighted the significance of the findings, noting the broad interval of copper minerals as a highly encouraging start to the drilling program and a strong validation of their geological model.
