Encounter Resources defines new niobium belts within Aileron

Encounter Resources (ASX:ENR) has intersected more shallow, “high-grade” mineralisation via aircore drilling within the Aileron Project in Western Australia. 

Executive Chairman Will Robinson says drilling is defining new belts of shallow niobium-rare earths carbonatite hosted mineralisation in the West Arunta region. 

At the Crean target, drilling returned 46m @ 3.1% niobium pentoxide from 60m to the end of the hole, including 4m @ 6.4% niobium pentoxide from 84m. 

Encounter Resources, which has a market capitalisation of $329.1 million, says the results confirm continuity along strike of the shallow mineralisation at Crean, with this mineralisation open to the west. 

Drilling has resumed at the target, with the aim to extend the mineralised trend westward. 

At the Emily target, drilling returned 16m @ 2.7% niobium pentoxide from 50m; and 20m @ 2.7% niobium pentoxide from 41m. 


The company says additional drilling will test west of the mineralisation identified to date. 

“Highly enriched, near-surface mineralisation has now been intersected at both the Crean and Emily targets, which are located on separate structures at Aileron, over 10km apart,” Robinson says.

“The aircore rig is currently completing further drill sectors at the western end of Crean and will then return to Emily and Green.” 

The 2024 aircore drilling program is designed to rapidly test and define areas of mineralisation near major structures across key targets uncovered at the Aileron Project. 

Based on the latest assays, a follow-up reverse circulation and potentially diamond drilling program will be used to test the depth extent of this mineralisation and provide further geological and metallurgical information. 

Further to this, a diamond drillhole is in progress at the intersection of the Elephant Island and Stromness Faults, where several aircore holes did not penetrate cover. 

The company has also completed its first-phase wide-spaced aircore drilling program at Green, with assays from the first batch of samples expected this month.

Encounter resources is an Australian mineral exploration company with a primary focus on copper and niobium-rare earths in Australia. The company controls a portfolio of 100% owned projects across Australia.
