Legacy Minerals Initiates Major Copper-Gold Drilling Campaign at Emu Prospect

Sydney, Australia – June 12, 2026 – Legacy Minerals (ASX: LGM), a growth-focused mineral exploration company, has officially commenced a pivotal diamond drilling program at its Emu Copper-Gold Prospect. Located within the broader Mt Carrington Project in northern New South Wales (NSW), Australia, this initiative represents a significant step forward in evaluating a compelling target that has remained largely untested by modern exploration techniques for half a century. The program underscores Legacy Minerals' strategic focus on identifying and advancing high-quality copper and gold assets within Australia's prolific mining landscape, a move keenly watched by industry professionals and investors alike given the robust demand outlook for these critical metals.

The Emu Copper-Gold Prospect is situated approximately 8 kilometers north of Drake, NSW, within exploration licence 6273. It forms an integral part of a regional caldera-margin trend, a geological setting often associated with significant polymetallic mineral deposits. This current drilling campaign is designed to provide crucial insights into the subsurface geology and potential scale of mineralization, leveraging advanced geophysical data to guide precision targeting.

Strategic Exploration Underway at Emu Copper-Gold Target

The diamond drilling program at Emu is an ambitious undertaking, planned to encompass up to eight drill-holes, totaling an estimated 4,000 meters. These holes will be distributed across five distinct drill pad sites, each strategically positioned to test specific geological anomalies. The individual drill-holes are projected to reach substantial depths, potentially extending up to 500 meters, allowing for thorough investigation of the target zones at various stratigraphic levels. Legacy Minerals anticipates that drilling activities will continue over the next three months, with the possibility of follow-up work contingent upon initial results and geological interpretations.

Copper stands as the primary focus of this exploration endeavor at Emu. This commodity emphasis is well-justified by the historical context of the area, which includes past mining operations at the Emu Creek copper mine and documented copper mineralization throughout the region. While copper is the main driver, the prospect's "copper-gold" designation highlights the potential for co-occurring gold mineralization, an attractive characteristic for multi-commodity resource development.

Technical Foundation: Geophysics Guides Precision Drilling

The selection and prioritization of drill targets at Emu are the culmination of sophisticated geological and geophysical analysis. Specifically, the drilling program is concentrated on two key zones: the Emu Porphyry Core and the Emu Alteration Halo SE targets. These distinct exploration zones were methodically identified following an airborne mobile magnetotellurics (Mobile MT) geophysical survey.

The Mobile MT survey, a cutting-edge technique, provided detailed subsurface resistivity data, which allowed geophysicists to interpret these areas as discrete anomalies. The Emu Porphyry Core is interpreted as a possible porphyry-style intrusive body. Porphyry deposits are revered in the mining industry for their potential to host very large-scale, often long-lived, copper-gold-molybdenum mineralization. The Emu Alteration Halo SE, conversely, is interpreted as a silicified alteration halo within the caldera. Alteration halos, particularly those rich in silica, are characteristic features surrounding porphyry systems and epithermal deposits, indicating intense hydrothermal activity that can precipitate significant concentrations of precious and base metals. The integration of such modern geophysical data with historical geological information has been crucial in defining these high-priority, compelling targets that had previously eluded modern systematic exploration.

Historical Promise Meets Modern Exploration

A compelling aspect of the Emu Prospect is its unique history. Christopher Byrne, CEO and Managing Director of Legacy Minerals, underscored this point, stating, "The commencement of drilling at Emu marks the first modern drill test of a compelling copper-gold porphyry-epithermal target that has not seen a drill rig in 50 years." This long hiatus highlights the potential for substantial, undiscovered mineralization, as older exploration efforts often lacked the technical sophistication and geological understanding available today. The re-evaluation of such historically recognized mineralized areas with contemporary methodologies is a common and often successful strategy in the mining industry.

Furthermore, the broader Mt Carrington Project area has demonstrated significant copper potential. Legacy Minerals has highlighted that substantial areas within the project remain untested, drawing attention to previous drilling at the Mt Carrington Prospect that yielded impressive historical intervals, including:

  • 18.9 meters at 5.8% copper
  • 10.1 meters at 7.26% copper

These historical high-grade intercepts, while not directly from the Emu Prospect itself, serve as a strong indicator of the overall metallogenic fertility and potential for high-grade copper mineralization within the larger Mt Carrington Project area, bolstering confidence in the Emu target's prospectivity.

The Broader Mt Carrington Project and Regional Significance

The Emu Prospect is not an isolated target but rather one of several high-priority sites within the expansive Mt Carrington Project. Along with the nearby Mascotte and Battery prospects, Emu has been designated as a top-tier regional target based on the insights gained from recent geophysical surveys. These prospects collectively lie along the same regional caldera-margin trend, a geological structural setting known to host economic mineralization across the New England Orogen of NSW.

This regional setting is particularly significant because the same caldera margin trend also hosts the existing Mt Carrington Mineral Resource, which boasts an impressive 1.2 million ounces of gold equivalent (AuEq) or 115 million ounces of silver equivalent (AgEq). The proximity and geological affinity to this established resource lend considerable credibility to the exploration efforts at Emu. It suggests that the geological processes responsible for the Mt Carrington resource may extend into the Emu area, enhancing the potential for discovering additional economic mineralization.

Market Implications and Copper's Critical Role

The commencement of significant exploration for copper and gold at a promising prospect like Emu carries substantial implications for the broader mining industry and commodity markets. Copper, often referred to as "Dr. Copper" for its perceived ability to predict economic health, is a fundamentally critical metal for the global transition to a green economy. Demand for copper is projected to escalate dramatically, driven by:

  • Electrification of transportation (Electric Vehicles)
  • Expansion of renewable energy infrastructure (wind turbines, solar panels)
  • Global infrastructure development
  • Technological advancements in electronics and communication

New, high-quality copper discoveries are essential to meet this burgeoning demand and mitigate potential supply deficits. A successful outcome at Emu could contribute to securing future copper supply, providing a valuable asset to Legacy Minerals and potentially attracting major mining interest. Gold, while having distinct market drivers rooted in its role as a safe-haven asset, inflation hedge, and store of value, also remains a highly sought-after commodity. The combination of both metals in a porphyry-epithermal system enhances the economic attractiveness and resilience against commodity price fluctuations.

Looking Ahead: Data Integration and Project Outlook

As the drilling program progresses over the coming months, Legacy Minerals has committed to a transparent reporting strategy. Results from the drilling campaign will be released as assay data becomes available. This data, which provides precise chemical analyses of rock samples, will be meticulously integrated with existing geological, geochemical, and geophysical datasets. This holistic approach is fundamental to building a comprehensive understanding of the Emu Prospect's geology and mineralization controls, ultimately refining exploration targeting and informing future work programs.

The careful integration of diverse datasets allows for better predictive modeling, reducing exploration risk and increasing the probability of making significant discoveries. Should the drilling confirm the presence of economic mineralization, the possibility of follow-up work, including additional drilling, metallurgical test work, and resource definition studies, would likely ensue. Such steps are critical in advancing a prospect from an exploration target to a potentially viable mining project.

Recent Corporate Developments: Expanding NSW Footprint

In addition to the drilling activities at Emu, Legacy Minerals has recently demonstrated its broader corporate strategy to expand and diversify its exploration footprint within New South Wales. Earlier in June 2026, the company announced the signing of a binding earn-in and farm-in agreement with Peak Gold Mines, a wholly-owned subsidiary of Aurelia Metals. This agreement pertains to Legacy Minerals' Cobar Project, also located in NSW. The Cobar Basin is another highly prospective region known for its world-class gold, copper, and base metal deposits.

This strategic partnership with Aurelia Metals, an established Australian gold and base metals producer, allows Legacy Minerals to bring additional capital and expertise to its Cobar tenements while retaining exposure to potential exploration success. Such agreements highlight Legacy Minerals' approach to maximizing the value of its extensive project portfolio through a combination of self-funded exploration, as seen at Emu, and strategic collaborations, as demonstrated at Cobar.

The initiation of drilling at the Emu Copper-Gold Prospect is a significant milestone for Legacy Minerals, representing a concerted effort to unlock substantial mineral potential within a historically active yet underexplored region of NSW. With modern exploration techniques guiding the path, the industry will be closely watching the assay results from this campaign, which could signify the emergence of a notable new copper-gold resource in Australia.
