Javelin Minerals (ASX:JAV) is set to drill two deep, untested gold-copper targets beneath Coogee from the start of September, with a two-hole diamond program targeting large magnetic anomalies at Coogee North and Coogee West.
Both holes are being co-funded through WA’s Exploration Incentive Scheme, with ~1,800m of drilling planned over six weeks.
The known gold may be sitting above something bigger
Coogee already hosts 3.6Mt @ 1.08g/t Au for 127,000oz, plus 1Mt @ 0.41% Cu for 4,122t Cu.
At Coogee North, that resource sits above a large magnetic anomaly modelled around 700m below surface.
Shallow drilling has already returned:
- 5m @ 14.22g/t Au and 4m @ 1.91% Cu
- 7m @ 6.42g/t Au and 7m @ 2.54% Cu
The deeper source of that magnetic response has never been tested.

Coogee West gets its first real look
The second hole will target Coogee West, where shallow aircore drilling has defined a broad 900m by 500m bedrock gold anomaly.
The magnetic target is interpreted around 450–600m below surface and, again, has never seen bedrock drilling.
That gives Javelin two genuine first-pass deep tests rather than simple step-outs around known mineralisation.
General Manager Mark Cossom said the program is designed to test whether the large magnetic anomalies represent deeper intrusive systems linked to the shallow gold-copper mineralisation.
What’s next
The rig is due to mobilise in late August and start drilling on 1 September.
Coogee North will be drilled to around 800m, while Coogee West is planned to roughly 1,000m.
The shallow mineralisation is already there, now Javelin gets to find out what is feeding it.
