Legacy Minerals Accelerates Exploration at Mt Carrington with Targeted Geophysical Surveys

SYDNEY, NSW – Legacy Minerals (ASX: LGM), an emerging explorer focused on high-demand metals, has commenced crucial ground geophysical surveys at its flagship Mt Carrington Project in New South Wales (NSW), Australia. This strategic move, announced on June 25, 2026, marks an important step in unlocking the full potential of the project's highly prospective Battery and Mascotte prospects, which have shown compelling evidence of extensive gold, silver, and copper mineralisation.

The Mt Carrington Project, managed by Legacy Minerals under exploration licences EL6273, EL9616, EL9727, and ALA75, is situated within a historically rich mining region known for its epithermal gold-silver deposits and volcanogenic massive sulphide (VMS) occurrences. The current exploration phase underscores the company's systematic approach to developing its asset portfolio and responding to the robust market demand for precious and base metals.

Advanced Geophysical Techniques Deployed

Legacy Minerals has engaged specialist contractor Fender Geophysics to conduct a dipole-dipole induced polarisation (DDIP) survey across six priority lines within the Battery and Mascotte prospects. DDIP is a highly effective geophysical technique used in mineral exploration, particularly for identifying sulphide-rich mineralisation often associated with epithermal gold-silver and porphyry-style copper deposits. This method involves injecting current into the ground and measuring the induced voltage, providing valuable insights into the subsurface chargeability and resistivity, which can indicate the presence of disseminated or massive sulphides linked to valuable metal occurrences.

The fieldwork for this extensive survey is projected to span approximately three weeks. Following the completion of data acquisition, the subsequent analysis and review are anticipated to be rapid, with results expected soon thereafter. This timely delivery of data is crucial for maintaining momentum in the company’s broader exploration strategy at Mt Carrington.

Targeting Extensions to High-Grade Mineralisation

The primary objective of the DDIP survey is explicitly designed to identify extensions to already established high-grade gold and silver zones at the Mascotte prospect. Additionally, the survey aims to assist in locating potential higher-grade copper mineralisation at the Battery prospect. This dual focus highlights the multi-commodity potential of the Mt Carrington Project, aligning with the increasing global demand for both traditional safe-haven assets like gold and critical industrial metals such as copper and silver.

Data derived from these sophisticated geophysical surveys will not be viewed in isolation. Instead, it will be meticulously combined with ongoing surface sampling and geological mapping activities. This integrated approach is fundamental to building a comprehensive understanding of the subsurface geology and mineralisation controls. The ultimate goal is to define extensions of known mineralisation and provide precise guidance for future drilling programmes, ensuring that subsequent drill campaigns are highly targeted and capital-efficient.

Building on Historical Drilling Success

The current geophysical work at Mascotte and Battery is predicated on encouraging results from earlier drilling campaigns, which have already demonstrated significant mineralisation. Notably, previous drilling at Mascotte yielded impressive intersections, including:

  • Drill-hole MSDD001: 40 metres at 1 gram per tonne (g/t) gold from a depth of 151 metres, which contained a higher-grade interval of 9 metres at 2.7 g/t gold.
  • Further in MSDD001: An additional finding reported 57 metres at 0.3 g/t gold from 81 metres, including 8 metres at 1.3 g/t gold from 129 metres.
  • Drill-hole MSDD003: A highly significant 1-metre intersection returned 18.7% lead, 8.7% zinc, and 43 g/t silver, indicating the polymetallic nature of the mineralisation at Mt Carrington, which often characterises VMS or epithermal systems.

These historical intercepts provide a robust foundation for the current exploration efforts, suggesting the presence of a substantial and well-mineralised system that warrants further systematic investigation and resource definition.

A Holistic Project Development Strategy

Legacy Minerals' work at Mt Carrington is part of a broader, multi-faceted exploration and development strategy. Concurrent with the geophysical surveys at Battery and Mascotte, the company is continuing with an active drilling programme at its Emu Prospect. Assay results from the Emu drilling are eagerly anticipated, with a timeline of four to six weeks following the completion of core processing. Such staggered exploration activities allow for continuous news flow and efficient utilisation of resources.

Beyond the immediate drilling and geophysics, Legacy Minerals is actively working towards updating its economic understanding of the project. This includes the development of a new 2026 Mineral Resource Estimate (MRE), a critical milestone in the mining project lifecycle. A robust MRE is essential for quantifying the economic potential of a deposit and serves as the foundational dataset for subsequent economic studies. Following the completion of the MRE, the company plans to move forward with an upcoming scoping study, which will provide an initial economic assessment of the project's viability and inform future development decisions.

Leadership Puts Confidence in Strategy

Mr. Christopher Byrne, CEO and managing director of Legacy Minerals, articulated the significance of the current exploration activities. “The commencement of the DDIP survey at the Battery and Mascotte prospects represents an important step forward in unlocking the potential of these highly potential target areas,” Mr. Byrne stated. His commentary underscores the strategic importance of systematically advancing the project through data-driven exploration.

Mr. Byrne further elaborated on the geological interpretations underpinning the exploration strategy: “Our technical team identified strong evidence for a well-mineralised epithermal gold-silver system at Mascotte and a potentially large, fertile copper system at Battery. These surveys will deliver critical subsurface data to refine our geological model and support the design of follow-up targeted drilling programmes.” This statement highlights the understanding that robust geological models, informed by comprehensive data sets like DDIP, are paramount for successful exploration in complex mineral systems.

Market and Industry Implications

The commitment by Legacy Minerals to advanced geophysical exploration at Mt Carrington holds significant implications for the broader mining industry and investors. In an era of increasing demand for battery metals and a renewed focus on secure supply chains, projects like Mt Carrington, which demonstrate polymetallic potential (copper, gold, silver, lead, zinc), are particularly attractive. Copper continues to be a crucial component for the global energy transition, necessary for electric vehicles, renewable energy infrastructure, and grid modernisation. Gold and silver, meanwhile, maintain their roles as valuable monetary metals and industrial inputs.

For investors, systematic exploration leading to robust resource definition reduces project risk and enhances the certainty of future production. The use of advanced techniques like DDIP demonstrates a commitment to efficient exploration, aiming to minimise drilling costs by targeting high-probability zones. The progression from geophysical surveys to drilling, then to a new MRE and scoping study, follows a well-established pathway for project de-risking and value creation in the mining sector.

Furthermore, the location in NSW, Australia, a tier-one mining jurisdiction with established infrastructure and a supportive regulatory environment, adds another layer of attractiveness to the Mt Carrington Project. The active exploration environment in regions like NSW contributes significantly to regional economies through job creation, investment, and local procurement.

Outlook and Next Steps

The immediate outlook for Legacy Minerals at Mt Carrington remains dynamic. Following the current DDIP surveys, the integration of geophysical data with existing geological information will lead directly to the refinement of drill targets. Concurrent activities include:

  • Waiting for assay results from the ongoing drilling at the Emu Prospect, expected in four to six weeks.
  • Preparations for a new 2026 Mineral Resource Estimate, which will incorporate all new and historical data.
  • Planning for an upcoming scoping study to assess the economic parameters of the Mt Carrington Project.
  • Scheduling the drill rig to move from Emu to Mascotte for further follow-up drilling, contingent on the initial results from the geophysical surveys and prior drilling.

Legacy Minerals is positioning Mt Carrington as a significant multi-commodity project with considerable growth potential. The current geophysical surveys are a testament to the company's diligent approach to understanding and unlocking this potential, setting the stage for future resource growth and economic assessment.
