Javelin unveils eight big new targets at WA copper-gold project

Javelin Minerals has uncovered a set of big copper-gold targets at its Coogee project just 50 kilometres south of Kalgoorlie in a move that could potentially turbo-charge the high-grade goldfield - already host a 127,000-ounce gold resource and more than 4000 tonnes of copper.

At its Coogee West and Coogee North prospects, Javelin has locked onto eight new magnetic and gravity bullseye targets withing two prime structural corridors which the company says are shaping up as very interesting hot spots that could be harbouring significant accumulations of copper/gold.

Management says discovery of the anomalies came down to a project-wide review spearheaded by a newly appointed exploration boss who re-analysed the historic data and connected the dots between known mineralisation, magnetic signatures and deep-seated intrusions.

Notably, the main Coogee deposit was originally mined by Ramelius Resources back in 2014, producing 30,000 ounces at an impressive 4.1grams per tonne (g/t) gold. Most of the surrounding ground however, has hardly been touched since. Javelin is seeking to emulate the success of companies like Spectrum Metals and Spartan Resources, both of which found new gold discoveries worth hundreds of millions of dollars lurking nearby old mined out pits.

Just five kilometres west of Coogee, Javelin has lit up three powerful magnetic and gravity targets at its Coogee West prospect - stretching up to three kilometres long and perched on the edge of what appears to be a buried intrusive body. 

The company says the set-up is a doppelganger for the multi-million-ounce Junction and Mt Charlotte gold deposits just down the road. Shallow drilling in the past hit up to 1.38g/t gold at the bottom of holes, however, the deeper source has never been drilled.

Up at Coogee North, just beyond the main deposit, the re-crunched data has uncovered five new bullseye targets lying right beneath a zone that’s already delivered some barnstorming gold and copper hits.

Historic drilling at site hit a thick 5-metre section of high-grade dirt running at 14.22g/t gold and a 3m slice going 2.31 per cent copper. Other standout strikes include a 7m hit grading 6.42g/t gold and 2.54 per cent copper. 

Notably, the rocks show signs of magnetite, epidote and sulphide minerals, which is a classic skarn-style signature often linked to mineral-rich intrusive orebodies. The company says despite the solid intercepts, modelling of the ground structure shows the true heart of the magnetic source has yet to be drilled, adding serious weight to the prospectivity of the area.

Javelin’s Coogee gold project is parked right in elephant country too, tucked into the southern end of the Kalgoorlie’s structural geological belt in Western Australia’s famed Eastern Goldfields.

The grounds sit alongside some of the most mineralised fault lines in the region, including the powerhouse Lefroy Fault, which feeds Gold Fields’ 3-million-ounce St Ives mine, Northern Star’s Jubilee-New Celebration operations, and the monster 39-million-ounce Super Pit at Kalgoorlie’s Golden Mile. 

The nearby Mt Monger fault also plays host to Red 5’s gold-producing Randalls and Daisy Milano mines – placing Coogee squarely in a very rich neighbourhood. 

Javelin Minerals executive chairman Brett Mitchell said: “These targets are clearly compelling exploration opportunities. The wider project area has been exposed to very little exploration and basically no deeper drilling, with the previous focus having been on establishing near-term mineable ounces.”

The company is now planning to roll out the rotary truth teller with a systematic air-core and diamond drilling blitz in the first quarter of next year to give the new anomalies a serious workover.

With eight untested magnetic and gravity targets now in its sights — and a proven track record of gold and copper already in the ground — Javelin is shaping up for a high-impact start to 2026. 

Backed by a freshly topped-up $4.5 million war chest and a geological address surrounded by giants, the company is about to roll out the rigs and determine if Coogee is yet another old mined out pit that is harbouring big new undiscovered deposits nearby.
