Lanthanein Resources is loading up a more than 10,000m drill program in a major push to prove up a target in what has become one of the world’s hottest domains for rare earths exploration.

New ironstones have been defined at Lyons in sampling, with an additional 25 outcrop samples identified through satellite data.

North easterly trending ironstones of up to 1.4km in length have returned sample grades of up to 0.4% total rare earths oxides, within Lanthanein’s (ASX:LNR) large LI-01 carbonatite target.

Anomalous carbonatite indicator minerals have also returned up to 0.25% Nb2O5, 0.3% P2O5 and 0.72% ZrO2 from four newly discovered ironstones.

This is all within 1.5km of Hastings Technology Metals’ major Yangibana project, where it is proposing to mine new open cuts to supply magnet rare earths to produce permanent magnets for EVs, hi-tech applications and wind turbines.

Fresh fieldwork

Lanthanein says fieldwork following up its Worldview satellite targets has demonstrated the potential to find both high grade rare earths mineralisation and larger tonnage REE and niobium within the main LI01-01 carbonatite target area.

“The Lyons rare earths project has proven rare earth mineralisation within ironstones within 1.4km of the Hastings Technology Metals proposed open cuts,” Lanthanein technical director Brian Thomas said.

“Continuing exploration has shown the occurrence of carbonatite mineralisation within our main carbonatite target at LI01-01.”

Get ready for the drill down

Two carbonatite targets at Lanthanein are set to be drilled in co-funded deep holes supported by the WA Government’s Exploration Incentive Scheme.

The diamond holes will test the LI01-01 and LI03-01 carbonatite targets down to 450m, tracking their magnetic margins.

It comes ahead of a more than 10km program due to start in April testing ironstone trends and carbonatite targets under thin cover.

Like Yangibana and Lynas Rare Earths’ world class Mt Weld deposits, WA’s carbonatites have become an increasingly important source of rare earths mineralisation on a global scale, with potential to also host economic quantities of thorium, uranium, niobium, yttrium and phosphorous.

“Together with the financial support of the WA Government, two of our Carbonatite targets will be tested with deep diamond drill holes along their magnetic altered margins to better define the geology in an area that remarkably has no historical exploration,” Thomas said.

“Following the drilling of the Carbonatite targets, Lanthanein will continue with an extensive +10,000 metre RC drilling program to test for rare earth elements associated with extensive ironstone targets defined by both geophysics and the high-resolution Worldview satellite imagery.”

Lanthanein says within its Lyons Block and along the Bald Hill lineament a number of carbonatite intrusions have been modelled from the airborne magnetics “with a similar dimension to the Mt. Weld carbonatite”.
