References in this MD&A to “REO” (rare earth oxide) mean the sum of Ce₂O₃, La₂O₃, Pr₂O₃, Nd₂O₃, Eu₂O₃, Sm₂O₃, Gd₂O₃, Tb₂O₃, Dy₂O₃, Ho₂O₃, Er₂O₃, Tm₂O₃, Yb₂O₃, Lu₂O₃ and Y₂O₃, and references to “NdPr” distribution mean (Nd₂O₃ + Pr₂O₃) / REO x 100. REO values reported in this MD&A are calculated as the sum of individual rare earth oxide components and are not directly measured assay results. Individual rare earth elements are reported by the analytical laboratory in parts per million (ppm) on an elemental basis, and each element is converted to its corresponding oxide using a fixed gravimetric conversion factor based on the ratio of the molecular weight of the oxide to the atomic weight of the corresponding element, calculated as: Oxide (ppm) = Element (ppm) x Conversion Factor. The REO value reported for a given sample or interval is the arithmetic sum of the fifteen individual oxide values (ppm), converted to a percentage as: REO (%) = Σ (individual oxides, ppm) ÷ 10,000. The element-to-oxide conversion factors used by the Company are: Ce to Ce₂O₃ (1.1713); Dy to Dy₂O₃ (1.1477); Er to Er₂O₃ (1.1435); Eu to Eu₂O₃ (1.1579); Gd to Gd₂O₃ (1.1526); Ho to Ho₂O₃ (1.1455); La to La₂O₃ (1.1728); Lu to Lu₂O₃ (1.1371); Nd to Nd₂O₃ (1.1664); Pr to Pr₂O₃ (1.1703); Sm to Sm₂O₃ (1.1596); Tb to Tb₂O₃ (1.1510); Tm to Tm₂O₃ (1.1421); Y to Y₂O₃ (1.2699); and Yb to Yb₂O₃ (1.1387). REO values do not imply any metallurgical recovery, as recoveries have not yet been established for the Company’s properties. The individual rare earth oxide values underlying each REO grade reported by the Company for the Rift Project, including REO calculations and conversions, are available on the Company’s website at www.apexcriticalmetals.com/projects/rift-rare-earth-project/#reo_disclosure.
