Special Report: Javelin Minerals has picked out key targets for upcoming exploration drilling at its Coogee West gold and copper project near Kalgoorlie in WA, after reprocessing ground and aeromagnetic survey data.

The highly promising, untested gold-copper targets were not previously identified due to extensive alluvial cover and limited historical aircore drilling that did not adequately test these targets below 30m.

That highlights the untapped potential left behind at the project, where the main Coogee deposit was briefly mined by multi-billion-dollar ASX mid-cap Ramelius Resources around a decade ago.

Notable examples that Javelin Minerals (ASX:JAV) intends to test in the drill program, scheduled to begin in the September quarter, include 3km and 1.8km strike gold trends that were highlighted by geophysics.

“We know that Coogee hosts a significant gold system in a world-class location, situated on the edge of the renowned St Ives goldfield,” executive chairman Brett Mitchell said.

“Despite these outstanding credentials, large areas of the project remain undrilled.

“These geophysical results highlight the substantial exploration upside at Coogee West, with numerous compelling targets identified. We are now fine-tuning plans for an exploration program with the aim of drilling these targets in the September quarter.”

Coogee West

The Coogee project is about 20km northeast of Kambalda and 55km south of Kalgoorlie on the northern side of Lake Lefroy.

It sits within a fertile greenstone belt that contains multiple gold deposits and widespread gold occurrences.

Besides St Ives, other notable nearby deposits include Coogee, which is owned by Javelin, Salt Creek, Daisy Milano and Lucky Bay.

Coogee has an existing resource of 3.65Mt at 1.08g/t gold, or 126,685oz of contained gold.

JAV’s review has delineated five high-priority targets along known mineralised trends, within favourable lithological settings, and coincident with geophysical anomalies.

CG-04 is a discrete, untested, circular “bulls-eye” magnetic anomaly about 1.5km west of the Coogee pit.

It is interpreted to commence from a depth of 300 vertical metres, extending to approximately 1km, and remains completely untested by drilling.

The CG-05 target area comprises anomalous gold intersections from wide-spaced aircore drilling conducted by Ramelius Resources (ASX:RMS) in 2015 that was followed by two diamond drillholes, which returned broad gold intervals with minor associated copper.

Observed lithologies are consistent with those along the Coogee pit trend.

CG-06 comprises the two magnetic anomalies of 1.8km and 3km while historical drilling intersected anomalous gold values adjacent to a well-defined magnetic aureole at CG-08 which is also semi-coincident with a gravity anomaly.
