Mount Burgess Mining (ASX: MTB) has identified some additional rare earth elements from tests at the Tsumkwe Rare Earth Project in Namibia.
A further eight tests have confirmed that the rare earth element mineralogy is predominantly comprised of synchysite - mainly associated with K feldspar, ranging in size from 5 microns up to 200 microns.
Mount Burgess said that the rare mineral synchysite was confirmed by XRD by the CSIRO in May this year.
The results are from SEM/PLM analysis of drill chip samples from a recent percussion hole.
Whilst monazite is a common trace mineral in granites and mineral sands/placer deposits, synchysite and bastnesite are rarely detected in most rocks.
Mount Burgess said that the predominance of synchysite in this instance is therefore seen as prospective.
