Structural Faults at Wilandra Raise Stakes for Remobilised Copper Deposits, G11 Plans Surveys

Exploration Advances at Wilandra Copper Corridor

G11 Resources Limited (ASX: G11) has delivered a compelling update in its March 2025 Quarterly Activities Report, spotlighting two newly defined target areas, Bedford and Chevron, within its Wilandra Copper Corridor in New South Wales. These targets emerged from a comprehensive review of litho-geochemical, structural, and geophysical datasets collected during 2024, underscoring the company's methodical approach to expanding its copper-rich massive sulphide footprint.

The Wilandra Copper Corridor already hosts a significant volcanogenic massive sulphide (VMS) system, with drilling and electromagnetic (EM) surveys confirming a semi-continuous strike length of approximately 4.2 kilometres. This system exhibits an average width of 5 to 6 metres and copper grades ranging between 1% and 2.5%, with mineralisation open along strike and at depth, an encouraging sign for further resource growth.

Geological Insights and Structural Controls

Key to the identification of Bedford and Chevron targets was the recognition of a distinct magnetic basalt unit acting as a pseudo-marker horizon for copper mineralisation. This horizon is traceable over an additional 10 to 15 kilometres along strike, suggesting a broader mineralised system than previously understood. Structural studies revealed folding of the lithological sequence and the presence of significant faults, notably the Bedford Fault and Chevron Fault, which are interpreted to have remobilised copper-rich sulphides into dilatant structural traps, prime sites for new massive sulphide deposits.

The Bedford target area is particularly notable for the intersection of the NNW-striking Bedford Fault with prospective stratigraphy, a setting conducive to remobilisation and concentration of copper mineralisation. Similarly, the Chevron target lies beneath a thin cover, masking surface expression but showing structural features ideal for hosting remobilised sulphides.

Next Steps: Electromagnetic Surveys and Exploration Outlook

Building on the success of 2024 EM surveys, which effectively identified copper sulphide mineralisation, G11 Resources plans to deploy Moving Loop Electromagnetic (MLEM) surveys over Bedford and Chevron starting mid to late May. These surveys aim to delineate bedrock conductors associated with copper-rich massive sulphides, guiding targeted drilling campaigns.

With the Wilandra system already defined to depths of 500 metres and open in multiple directions, the addition of Bedford and Chevron as priority targets significantly enhances the prospectivity of the Wilandra Copper Corridor. The company’s strategic focus on these targets aligns with its broader ambition to establish a new copper-rich VMS district within the under-explored Koonenberry Belt.

Financial Position and Project Scale

Financially, G11 Resources reported a cash balance of AUD 2.029 million at quarter-end, with exploration and operating expenditures continuing as planned. No new financing activities were recorded during the quarter, indicating prudent cash management aligned with ongoing exploration programs.

The Koonenberry Project, encompassing over 3,300 square kilometres and more than 200 kilometres of strike within the Koonenberry Belt, remains a cornerstone of G11’s portfolio. The belt’s complex structural architecture and diverse mineralisation styles, including copper, gold, nickel, and silver, offer multiple avenues for discovery and value creation.

Managing Director Richard Buerger, a qualified Competent Person under JORC standards, affirms the accuracy of the exploration data and the geological interpretations underpinning these new targets, lending credibility to the company’s forward-looking exploration strategy.
