Maiden trenching program returns rare earth element (REE) mineralisation in all 52
trenches completed at Grønnedal

Trench sample assays confirm high neodymium oxide (Nd2O5) ratios of up to 56% of
total rare earth oxides (TREO) with an average of 31%

Supported by

Pr+Nd assay results account for 60% of calculated TREO, indicating that the Grønnedal
mineralisation is enriched in the more valuable REE of Pr and Nd

Maiden drilling program at Grønnedal returns rare earth element (REE) mineralisation
for full length of all drill holes

Drilling results confirm high ratios of up to 50% of praseodymium and neodymium
(Pr+Nd).

REE mineralisation at Grønnedal is widespread and deep-seated

Potentially valuable polymetallic mineralisation identified in waste rock from the
historic Ivigtût cryolite mine.

The large volume of mineralised waste material could be processed to create
concentrates containing silver, zinc, gallium, copper, lead and gold.
