Fe Limited’s (ASX:FEL) partner Auris Minerals Ltd (ASX:AUR) has intersected visible primary copper mineralisation in diamond drilling at the Forrest prospect in the Bryah Basin of Western Australia.
The project is held 20% by FEL and 80% by Auris.

Auris exploration manager Matthew Svensson said: “The company is extremely excited to have intercepted primary copper sulphide mineralisation.
“This extends the footprint of known mineralisation, the extent of which remains open along strike and at depth.”
Auris shares opened more than 20% higher at 3.5 cents.

The drill rig is mobilising to the nearby Wodger prospect to drill one diamond hole aimed at laterally extend mineralisation to the north and to drill a diamond tail.
Drilling summary
A total of two diamond holes for 679.5 metres have been completed at Forrest and these have confirmed the existence of a northern down-plunge extension to known copper mineralisation.
Hole FPDD001, drilled to 231 metres depth, intersected 5 metres containing 10% malachite and chalcocite mineralisation from 125 metres associated with weathered, foliated ultramafic lithologies.
This hole tested the down plunge extension (120 metre step out) of copper mineralisation intersected in past drilling.
Hole FPDD002 intersected several zones of up to 5% bornite mineralisation associated with quartz carbonate and quartz veining.

The hole has been cased with 50mm PVC so that downhole electromagnetic (EM) surveying can be completed.
Mineralised intersections of drill core are being orientated, geologically logged and sampled. Samples will be submitted for multi-element analysis at ALS laboratory soon.
Next steps
The diamond drilling at Wodger prospect will consist of a 440-metre hole designed to intercept copper mineralisation interpreted 120 metres down plunge.
A diamond tail for about 120 metres is also planned with the aim of intersecting a moving loop EM anomaly.
