Sydney, NSW, Australia – Kuniko, a burgeoning player in the mineral exploration sector, has successfully concluded its phase two diamond drilling program at the Silica Hill prospect, an integral component of its Commonwealth Project situated within Australia's geologically esteemed Lachlan Fold Belt in New South Wales. The announcement, made on September 25, 2026, marks a pivotal step in the company’s efforts to advance its understanding and resource definition of this promising mineralized system.

Core Drilling Achievements and Objectives

The recently completed phase two drilling campaign at Silica Hill encompassed five diamond drill-holes, collectively reaching a substantial depth of 1,492 meters. This intensive program was strategically designed with dual objectives: firstly, to meticulously test and validate the interpreted Northern and Southern Lodes within the Silica Hill mineralized system; and secondly, to significantly expand the existing geological knowledge by penetrating deeper into the system than much of the historical drilling previously undertaken at the prospect. The deliberate focus on deeper exploration is a critical aspect of modern resource definition, aiming to uncover the true extent and continuity of mineralization that might be overlooked by shallower, historical efforts.

The Commonwealth Project: A Strategic Acquisition

Kuniko’s involvement in the Commonwealth Project commenced with its strategic acquisition in October 2025. Since then, the company has demonstrated a robust commitment to exploration, culminating in the drilling of 11 diamond drill-holes across the Commonwealth-Silica Hill system, representing a combined length of 2,731 meters. This comprehensive drilling initiative serves a fundamental purpose: to substantially enhance Kuniko's geological interpretation of the entire area. The insights garnered from this extensive drilling are directly intended to underpin and support the forthcoming update of the mineral resource estimate (MRE) for the Commonwealth-Silica Hill system. An accurate and updated MRE is a cornerstone of responsible mining development, providing a quantifiable basis for future operational planning, economic evaluations, and investor confidence.

Advancing Resource Estimation and Geophysical Insights

A key outcome anticipated from the completed drilling is the planned update of the mineral resource estimate, which Kuniko has scheduled for completion in the fourth quarter of 2026. This MRE update is not merely an administrative exercise; it represents a comprehensive re-evaluation of the mineral endowment based on new, higher-quality data. To further augment geological understanding, selected holes from the recently concluded phase two program have been meticulously prepared for downhole electromagnetic (DHEM) surveying. DHEM is a sophisticated geophysical technique employed to detect conductive responses in the subsurface, which can be indicative of the presence of sulphide mineralization. Such mineralization often hosts valuable base and precious metals. Kuniko highlighted that previous DHEM surveys at Silica Hill have already demonstrated the utility of this method by identifying significant connections between the known mineralized system and broader geophysical features, thereby offering crucial vectors for further exploration. The processing and sampling of drill core obtained from phase two are nearing completion, with the industry eagerly awaiting assay results, which are anticipated in October 2026. These assay results, providing detailed geochemical data, will be meticulously integrated into the updated resource modeling, forming the quantitative backbone of the revised MRE.

Leadership Perspective and Strategic Implications

Maja McGuire, Managing Director of Kuniko, underscored the significance of these achievements, stating, "Completing Phase 2 drilling is an important milestone for Kuniko, with 11 diamond holes now completed for 2,731m across the Commonwealth-Silica Hill system. The programme has significantly advanced our understanding of the mineralised system, with assays expected in October and planned DHEM surveys to provide further insight into potential extensions." Ms. McGuire's comments reflect the company's methodical approach to exploration, emphasizing the phased progression from initial drilling to detailed geophysical and geochemical analysis, all contributing to a holistic understanding of the deposit. Such milestones are vital for junior exploration companies like Kuniko, as they progressively de-risk projects and build shareholder value through systematic resource definition.

Broader Exploration and Regional Potential

While the immediate focus remains on resource estimation at Silica Hill, Kuniko is concurrently advancing broader exploration efforts across the wider Commonwealth-Silica Hill district. This parallel strategy is a common and prudent practice in the mining industry, ensuring that a company explores for new discoveries while simultaneously developing existing ones. The identification and prioritization of additional drill targets for future testing are being informed by a confluence of geological mapping, comprehensive geochemical analysis, and advanced geophysical surveys. This integrated approach leverages multiple datasets to pinpoint areas with the highest potential for new mineralization, maximizing the efficiency of future drilling campaigns. The broader regional work underscores Kuniko's commitment not only to defining the known resources but also to unlocking the full potential of its tenement package within a highly prospective mineral province.

Market and Industry Context: The Lachlan Fold Belt's Significance

The Lachlan Fold Belt (LFB) in New South Wales is globally recognized as one of Australia's most prolific mineral provinces, making Kuniko’s activities at the Commonwealth-Silica Hill project highly relevant to the broader mining industry and investment community. The LFB is renowned for hosting world-class porphyry copper-gold deposits, such as Newcrest Mining’s Cadia Valley operations, and significant epithermal gold-silver systems. These deposit types are often associated with sulphide mineralization, which the DHEM surveys at Silica Hill aim to identify. The strategic importance of the LFB stems from its rich geological endowment and a long history of successful mining. Companies operating in this region benefit from established infrastructure, a skilled workforce, and a generally supportive regulatory environment within Australia, a Tier-1 mining jurisdiction. Global demand for critical minerals, particularly copper and gold, continues to grow, driven by urbanization, industrialization, and the accelerating transition to renewable energy technologies. Discoveries and resource expansions in established regions like the LFB therefore carry substantial weight, providing secure and ethically sourced supply options for global markets. For Kuniko, success in defining and expanding resources at Commonwealth-Silica Hill could position it as a significant contributor to this vital supply chain, attracting further investment and potential development partnerships. The systematic approach adopted by Kuniko, involving phased drilling, geophysical surveys, and rigorous resource estimation, aligns with best practices in mineral exploration and serves to mitigate risks inherent in the early stages of project development.

Future Outlook and Investment Implications

The completion of phase two drilling and the subsequent analytical work represent a critical juncture for Kuniko. The forthcoming assay results in October 2026 will provide definitive quantitative data on the mineral grades and widths encountered, directly influencing the confidence and scale of the updated mineral resource estimate. The DHEM surveys, by probing for extensions of the sulphide mineralization, offer an opportunity to identify new zones of interest beyond the current geological model, potentially leading to further resource growth. Investors will be keenly watching the Q4 2026 MRE update, as it will provide a clearer picture of the project’s economic viability and potential scale. A positive MRE update could significantly enhance Kuniko’s valuation, attract strategic partners, and pave the way for pre-feasibility or feasibility studies. Furthermore, the parallel regional exploration efforts underscore Kuniko’s long-term vision for the Commonwealth Project, suggesting a commitment to sustained growth through ongoing discovery. The systematic de-risking of the project through comprehensive data acquisition and analysis positions Kuniko to potentially capitalize on the enduring demand for critical minerals, marking the Commonwealth-Silica Hill project as one to watch in the dynamic Australian mining landscape.
