Heavy Rare Earths (ASX:HRE) has applied for 410km² of adjoining exploration ground that would expand its Subron Rare Earths Project footprint in Western Australia by 268% to 562km².
Applications E63/2595 and E63/2596 comprise 142 blocks and cost less than $30,000 in application fees and upfront rent.
If granted, the new ground would cover interpreted strike extensions of the Blume, Hunley, and Seawolf prospects and give Heavy Rare Earths control of more than 50km of prospective structural corridors.
The targets were identified through an evaluation led by rare earth elements consultant Claudio Sheriff, combining regional magnetic data with existing drill results.
Managing Director Jason Barnett says the applications broaden the company’s exploration runway at Subron.
“Critically, this expanded ground captures the interpreted strike extensions of our standout Blume, Hunley, and Seawolf prospects,” Barnett says.
Previous drilling at Blume returned 3m @ 2,246 parts per million (ppm) total rare earth oxides (TREO) and 1,481ppm heavy rare earth oxides (HREO) from 36m, representing a 66% HREO ratio.
Hunley returned 2m @ 3,611ppm TREO and 1,751ppm HREO from 36m, while results from Seawolf include 2m @ 3,795ppm TREO and 1,918ppm HREO from 24m.
A further Seawolf intersection returned 8m @ 3,057ppm TREO and 1,344ppm HREO from 27m. Heavy Rare Earths describes Seawolf as its priority Subron target, although additional drilling is required to define the mineralisation.
The company has identified 10 ‘higher-grade’ HREO domains using a 300ppm cut-off. These contain 150 drill intervals and 454 individual 1m intervals above the cut-off, averaging 1,653ppm TREO and 579ppm HREO.
Heavy Rare Earths plans to pursue heritage access for the applied-for ground ahead of potential drilling. It is also assessing mineralogical and metallurgical test work and discussing the redomaining of Subron’s existing mineral resource around its HREO zones.
