Greenland Resources Inc. Reassays for Magnesium and Finds Critical Minerals Including Rare Earth Elements
Greenland Resources Inc. has collected and reassayed 233 reasonably distributed core samples from the Malmbjerg molybdenum orebody and has recovered rare earth mineralization up to 579.5 ppm of total rare earth oxide (TREO). The Company will be investigating the potential recovery of these rare earth minerals from the future Malmbjerg molybdenum operation. The Company selected the intervals from five diamond drill holes archived in Greenland. Intervals were chosen on the basis of the molybdenum grade being higher than the cutoff value in the proven and probable molybdenum reserves in the NI 43-101 Feasibility Study. Samples were assayed at SGS S. A in Vancouver, Canada for 56 elements including molybdenum, magnesium and rare earth elements. Analysis of the results has shown anomalous values in molybdenum, magnesium, and rare earths, and these samples are being sent for petrographic study. The goal is to identify the mineral species that contain the magnesium and the rare earth elements which will allow the Company to further study the distribution within the molybdenum orebody. The following table shows the range of the rare earth values from the elements on samples selected for the magnesium petrographic study. Gallium (Ga), another critical mineral in the US and the EU showed average values of 19.1 ppm. Light Rare Earth Elements: Lanthanum (La) minimum 4.00 ppm, maximum 92.20 ppm, average 18.43 ppm; Cerium (Ce) minimum 16.10 ppm, maximum 194.00 ppm, average 50.67 ppm; Praseodymium (Pr) minimum 2.79 ppm, maximum 21.96 ppm, average 7.19 ppm; Neodymium (Nd) minimum 13.10 ppm, maximum 77.60 ppm, average 30.05 ppm; Samarium (Sm) minimum 4.5 ppm, maximum 14.00 ppm, average 7.89 ppm. Heavy Rare Earth Elements: Europium (Eu) minimum 0.06 ppm, maximum 1.37 ppm, average 0.17 ppm; Gadolinium (Gd) minimum 3.63 ppm, maximum 12.49 ppm, average 7.15 ppm; Terbium (Tb) minimum 0.48 ppm, maximum 2.25 ppm, average 1.22 ppm; Dysprosium (Dy) minimum 2.51 ppm, maximum 14.12 ppm, average 7.66 ppm; Holmium (Ho) minimum 0.48 ppm, maximum 2.88 ppm, average 1.55 ppm; Erbium (Er) minimum 1.33 ppm, maximum 9.08 ppm, average 4.74 ppm; Thulium (Tm) minimum 0.19 ppm, maximum 1.44 ppm, average 0.74 ppm; Ytterbium (Yb) minimum 1.30 ppm, maximum 10.20 ppm, average 5.20 ppm; Lutetium (Lu) minimum 0.20 ppm, maximum 1.46 ppm, average 0.75 ppm. The Company has prepared samples for petrographic analysis to better understand the minerals that host the magnesium and the rare earth elements and then be able to determine a more extensive future assessment program for potential recovery and concentrate grades. In November 2025, GRI initiated a sampling program for initial metallurgical test work on magnesium recovery. Collection of 593.58 kg of material was from secure government storage facilities in West Greenland. Drillhole data from available core was reviewed and core intervals with molybdenum above the economic cut-off grade (ie ore grade material) and that also contained magnesium, were collected to make up the met test sample. The selected drillholes are all within the ore zone and are generally evenly distributed. A sodium peroxide fusion/combined ICP-OES and ICP-MS analysis (GE_ICP91A50) was completed at SGS Canada, in Burnaby, BC, Canada, and results have been received from the lab. Full QA/QC protocol has been applied to the sampling, including the collection of field duplicates as quarter core, and the insertion of blind certified reference materials and blanks into the sample stream at a rate of one of each in every 20 samples. Chain of custody of all samples by qualified independent personnel has been maintain through the whole sampling process. Initial samples are currently being selected for petrographic analysis to determine the minerology of the Mg samples. This will inform the upcoming metallurgical processing assessment work. The results of this initial test work will be used to determine a more extensive future assessment program for Mg recovery.
