      "text": "Notes:\na. The reporting standard for the Mineral Resource Estimate uses the terminology, definitions and guidelines given in the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Mineral Reserves (May 2014) as required by NI 43-101.\nb. Mineral Resources are inclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.\nc. The Mineral Resources are reported at a Diluted Net Smelter Return (NSR) Cut-off of US $180/tonne.\nd. The diluted NSR is defined as:\n• Diluted NSR (U.S. $) =\nRevenue per block Nb205 (diluted) + Revenue per block Tio2 (diluted) + Revenue per block Sc (diluted)\nDiluted tonnes per block\n• The diluted revenue from Nb2O5, TiO2, and Sc per block used the following factors:\n• Nb2O5 Revenue: a 94% grade recovery, a 0.696 factor to convert Nb2O5 to Nb, 82.36% assumption for plant recovery, and a US$ 39.60 kg selling price per kg of ferroniobium.\n• TiO2 Revenue: a 94% grade recovery, a 40.31% assumption for plant recovery, and an US$ 0.88 kg selling price per kg of titanium oxide.\n• Sc Revenue: a 94% grade recovery, a 1.534 factor to convert Sc to SC2O3, 93.14% assumption for plant recovery, and a US$ 3,675 kg is selling price per kg of scandium oxide.\ne. The diluted tonnes are a 6% increase in the total tonnes of the block.\nf. Price assumptions for FeNb, Sc2O3, and TiO2 are based upon independent market analyses for each product.\ng. Numbers may not sum due to rounding. The rounding is not considered to be material.\nh. Rare Earth Oxides (REO) were evaluated as a potential by-product of the mining of niobium, titanium, and scandium; thus the estimated values of the REOs are reported using the previously determined diluted NSR as derived from the Nb2O5, TiO2, and Sc Mineral Resources.\ni. The stated Light Rare Earth Oxides (LREO) grade (%) is the summation of La2O3 (%), Ce2O3 (%), Pr2O3 (%), and Nd2O3 (%) estimates.\nj. The stated Heavy Rare Earth Oxides (HREO) grade (%) is the summation of Sm2O3 (%), Eu2O3 (%), Gd2O3 (%), Tb2O3 (%), Dy2O3 (%), H02O3 (%), Er2O3 (%), Tm2O3 (%), Yb2O3 (%), Lu2O3 (%), and Y2O3 (%) estimates.\nk. The stated Total Rare Earth Oxide (TREO) grade (%) is the summation of LREO (%) and HREO (%).\nl. Numbers may not sum due to rounding. The rounding is not considered to be material.\nm. The effective date of the Mineral Resource, including by-products, is December 8th, 2021 (date of last assay received).",
