Kingfisher has seen significant successes exploring for rare earths (REE) at its Mick Well project, but it could well have a bigger prize – a string of exciting carbonatite REE targets along its Chalba target corridor.

Airborne geophysics have identified numerous potential carbonatite intrusion locations with geophysical responses, similar to the Mick Well area, across a 54km corridor in WA’s Australia’s Gascoyne mineral field.

This takes what was already an exciting tenement-scale REE discovery for Kingfisher Mining (ASX:KFM) at Mick Well – where drilling has returned results such as 5m grading 3.45% total rare earth oxides (TREO) within a geologically mapped strike length of 5km – up an order of magnitude to what the company describes as a “belt-scale” play.

Of particular interest is a large-scale target at Kingfisher South which consists of a central area defined by a distinct circular magnetic feature with a diameter of 2km, which is surrounded by an area of high thorium and potassium that extends over a length of more than 6km.

This target has a geophysical signature like other known carbonatite intrusions globally and within the region.

Executive director James Farrell said the airborne survey had highlighted the significant potential of the company’s belt-scale tenement holding in this globally important REE region by identifying numerous additional potential carbonatite intrusions along the 54km Chalba mineralised corridor.

“This is an enormously encouraging early development in the project generation, expanding our footprint beyond the Mick Well area, where we made our first breakthrough high grade REE discovery only 12 months ago,” he added.

“We are extremely excited and are looking forward to following up these dominate targets which will hopefully confirms that our Chalba mineralised corridor is world class.”

Multitude of REE targets

Kingfisher has identified 10 high priority targets using a combination of magnetic, potassium and thorium features.

These are spaced along the entire length of 54km Chalba target corridor and range in size from 0.7km2 to 18km2.

Besides Kingfisher South (CH10), the company has selected targets CH2, CH5, CH6 and CH8 for immediate surface mapping and sampling due to the presence of interpreted carbonates and circular or oval-shaped features which are indicative of intrusion pipes.

All targets will be ranked and included in its project generation activities in 2023 and beyond.
