Javelin’s Coogee Exploration Faces Key Test as Drilling Targets Unveiled

Exploration Upside at a Proven Gold-Copper Project

Javelin Minerals (ASX – JAV) has revealed compelling new exploration targets at its Coogee Gold Project in Western Australia, located near the prolific St Ives goldfield approximately 50 kilometres south of Kalgoorlie. A detailed review of historic exploration data, led by recently appointed General Manager of Exploration and Resources Mark Cossom, has identified large geophysical anomalies that align with known alteration zones and mineralisation signatures.

This reinterpretation of past data highlights substantial potential beyond the current JORC-compliant resource, which stands at 3.6 million tonnes grading 1.08 grams per tonne gold for 127,000 ounces, alongside a copper resource of 1 million tonnes at 0.41% copper containing over 4,100 tonnes of copper. The project benefits from a granted mining license and has seen limited recent exploration, particularly at depth, leaving significant upside to be tested.

Target Areas – Coogee West and Coogee North

The newly identified targets at Coogee West and Coogee North are supported by coincident geophysical and geochemical anomalies. At Coogee West, magnetic and gravity data suggest the presence of a differentiated intrusion at depth, a geological setting known to host major gold deposits in the region. Historic shallow drilling has revealed widespread gold anomalism in bedrock, with assays up to 1.38 grams per tonne gold, despite surface sampling challenges due to transported sediments from nearby Lake Lefroy.

Coogee North presents a unique opportunity with two distinct mineralisation styles – gold-only mineralisation along strike of the existing open pit and gold-copper mineralisation offset to the northeast. Previous drilling in late 2024 returned high-grade intersections including 5 metres at 14.22 grams per tonne gold and 3 metres at 2.31% copper, confirming the presence of a skarn-type mineralised system associated with epidote-magnetite alteration. Importantly, the main source of the geophysical anomaly remains untested at depth, underscoring the potential for significant discoveries.

Well-Funded and Ready to Drill

Javelin is well-positioned financially to advance this exploration phase, having recently completed a $4.5 million capital raising supported by cornerstone investor MEGA Resources. The company is actively negotiating to secure a reverse circulation drilling rig, with plans to commence drilling early in the first quarter of 2026. The upcoming program aims to systematically test these targets with a combination of air-core and diamond drilling to better understand the geological framework and expand the existing resource base.

Executive Chairman Brett Mitchell emphasised the significance of the findings, noting that the combination of geophysical signatures, geochemical anomalies, and favourable geology presents a substantial exploration upside. The strategic review led by Mark Cossom has allowed Javelin to step back from near-term mining focus and consider the broader potential of the Coogee project area.

Regional Context and Future Prospects

The Coogee Gold Project lies within the Kalgoorlie Terrane of the Eastern Goldfields Province, a highly prospective region within the Yilgarn Craton. Its proximity to major structural features such as the Lefroy and Mt Monger faults, which host some of Western Australia's richest gold deposits, adds further geological credibility to the targets. The presence of magnetite-associated alteration and skarn mineralisation styles aligns with known mineralising systems in the region, suggesting that Coogee could host significant additional resources.

As Javelin prepares to drill, the market will be watching closely for results that could materially enhance the project's value and extend the life of mining operations. The company’s methodical approach to exploration, combining historic data with modern geophysical techniques and targeted drilling, positions it well to unlock Coogee’s full potential.
