Cobra Resources (LSE:COBR) has finalised an 18-hole, 3,200-metre reverse circulation drilling campaign at the Blue Rose prospect within the Manna Hill Copper Project in South Australia, where the company holds a 12-month option to acquire the asset. Drilling intersected extensive zones of visible oxide and primary copper mineralisation in 10 holes, alongside molybdenite linked to quartz monzonite and diorite intrusions. The results strengthen the geological model pointing to a sizeable porphyry system in a state that hosts roughly 70% of Australia’s copper reserves.
According to management, early-stage observations indicate that drilling may be vectoring toward the core of a porphyry system. These findings are expected to guide the board’s decision on whether to exercise the Manna Hill option, which is internally viewed as having the potential to deliver a tier-one copper discovery. The programme also produced the project’s first multi-element portable XRF dataset, enhancing understanding of the structural and geochemical controls on mineralisation. Follow-up drilling is planned to test scale potential and potassic porphyry targets, while the company advances resource drilling at its Boland and Head rare earth assets, setting the stage for an active 2026. Positive outcomes could materially improve the group’s copper resource base.
From a financial perspective, Cobra remains pre-revenue, with ongoing losses and continued cash burn weighing on its near-term outlook. A debt-free balance sheet provides some mitigation, but valuation metrics are constrained by negative earnings and the absence of dividend yield data. On the technical front, the share price remains above key moving averages with constructive momentum indicators, although fundamentals continue to shape the broader investment case.
More about Cobra Resources Plc
Cobra Resources Plc is a South Australia-focused critical minerals developer advancing projects along the pathway to production. Its portfolio includes the Boland ionic rare earth discovery at the Wudinna Project — regarded as Australia’s only rare earth asset considered suitable for in situ recovery — as well as the optioned Manna Hill Copper Project in the Nackara Arc. In 2025, the company divested its Wudinna gold assets to sharpen its focus on copper and rare earth opportunities.
The group targets large-scale, low-cost and low-disturbance extraction opportunities within South Australia’s established mining region, positioning itself to benefit from sustained global demand for copper and rare earth elements.
