Just a month out from identifying 17 rare earth elements targets at its Arthur River project, Kingfisher has now uncovered evidence that a large-scale carbonatite system is present at the largest target.

A review of historical exploration at the LK1 target found that previous drilling had intersected broad zones of iron carbonate, which is interpreted to be associated with the intrusion of carbonatites – similar to the ironstone deposits seen at Dreadnought Resources’ Yin project.

Potassic alteration has also been intersected in drilling and identified from analysis of surface samples close to the ironstones.

The historical results and Kingfisher Mining’s (ASX:KFM) recent airborne geophysical survey has highlighted that LK1 covers a large target area with potential carbonatite plugs that extend over a strike length of 9km and a width of more than 6.5km.

It also highlights the potential of the Lockier target corridor to host carbonatite intrusive complexes, with numerous geophysical features and geochemical anomalies pointing to the potential presence for REE mineralisation associated with carbonatite intrusions.

“In January we announced the results from our airborne geophysics surveys which led to the identification of 17 large-scale carbonatite plug and dyke targets across the 84km of strike of our Chalba and Lockier target corridors,” executive director James Farrell said.

“We have now completed a review of historical exploration data which covers the largest target, LK1.

“The review has revealed an enormously exciting and significant body of evidence which supports the presence of a large-scale carbonatite system, including iron carbonates, fenite alteration as well as anomalous REE and pathfinder elements from previous drill holes and surface samples across the large target area.”

Field work at Arthur River is set to begin in March with full exploration plans to be outlined in the coming weeks.
