Javelin Minerals has announced the discovery of significant copper-gold targets at its Coogee project, located just 50 kilometres south of Kalgoorlie, Australia. This development could significantly enhance the existing high-grade goldfield, which already holds a resource of 127,000 ounces of gold and over 4,000 tonnes of copper. The newly identified targets are situated at the Coogee West and Coogee North prospects, where the company has pinpointed eight new magnetic and gravity targets within two promising structural corridors.
The main Coogee deposit, initially mined by Ramelius Resources in 2014, yielded 30,000 ounces of gold at a grade of 4.01 grams per tonne (g/t). Most of the surrounding area has seen minimal exploration since then. Javelin aims to replicate the successes of companies like Spectrum Metals and Spartan Resources, which have discovered valuable gold deposits near previously worked sites.
Exploration Strategies Unveiled
The recent discoveries stem from a comprehensive project review conducted by Javelin’s newly appointed exploration head. This analysis involved re-evaluating historical data to connect known mineralization with magnetic signatures and deeper geological features. At the Coogee West prospect, which lies just five kilometres from the main deposit, the exploration team identified three compelling magnetic and gravity targets that extend up to three kilometres. These targets are situated near what appears to be a buried intrusive body, resembling the prolific Junction and Mt Charlotte gold deposits nearby.
Previous shallow drilling at Coogee West recorded impressive results, including a hit of up to 1.38 g/t gold at the end of some drill holes. However, the deeper source has yet to be explored, leaving potential untapped.
At the Coogee North prospect, just beyond the central deposit, the revised data indicates the presence of five new targets directly beneath a zone that has previously delivered remarkable results. Historic drilling revealed a substantial 5-metre section of high-grade material averaging 14.22 g/t gold and a 3-metre interval at 2.31 percent copper. Additional noteworthy findings include a 7-metre section grading 6.42 g/t gold and 2.54 percent copper.
Potential for Significant Discoveries
The geological features of the area suggest the presence of magnetite, epidote, and sulphide minerals, which are characteristic of skarn-style deposits often associated with mineral-rich intrusive orebodies. Despite the solid intercepts obtained from previous drilling, Javelin maintains that the core of the magnetic source has yet to be explored, significantly enhancing the prospectivity of the Coogee area.
As Javelin Minerals advances its exploration efforts, the company is poised to potentially unlock further value in a region already noted for its rich mineral resources. This renewed focus on the Coogee project underscores the ongoing interest in Western Australia’s copper-gold landscape, where opportunities for significant discoveries abound.
