The estimate has an effective date of June 30, 2022.\nThe Mineral Reserve is based on the mine design, mine plan, and cash-flow model utilizing an average cut-off grade of 0.679% Nb2O5 with an NSR of US$ 180/t.\nThe estimate of Mineral Reserves may be materially affected by metal prices, environmental, permitting, legal, title, taxation, socio-political, marketing, infrastructure development, or other relevant issues.\nThe economic assumptions used to define Mineral Reserve cut-off grade are as follows:\nAnnual life of mine (LOM) production rate of ~7,450 tonnes of FeNb/annum during the years of full production.\nInitial elevated five-year production rate ~ 7,500 tonnes of FeNb/annum when full production is reached.\nMining dilution of ~6% was applied to all stopes and development, based on 3% for the primary stopes, 9% for the secondary stopes, and 5% for ore development.\nMining recoveries of 95% were applied in longhole stopes and 62.5% in sill pillar stopes.",

Price assumptions are based upon independent market analyses for each product as of June 30, 2022\nPrice and cost assumptions are based on the pricing of products at the \"mine-gate,\" with no additional down-stream costs required. The assumed products are ferroniobium (metallic alloy shots consisting of 65%Nb and 35% Fe), a titanium dioxide product in powder form, and scandium trioxide in powder form.\nThe Mineral Reserve has an average LOM NSR of US$ 563.06/tonne.\nOptimize Group has provided detailed estimates of the expected costs based on the knowledge of the style of mining (underground) and potential processing methods (by 3rd party Qualified Persons).\nMineral reserve effective date is June 30, 2022. The financial model was run after the estimate of the NSR above, which reflects a total cost per tonne of US$ 196.72 versus US$ 189.91. This is not considered a material change.\nPrice variances for commodities are based on independent market studies versus earlier projected pricing. The independent market studies do not have a negative effect on the reserve.",
