The estimate has an effective date of May 3rd, 2022.\nThe Mineral Reserve is based on the mine design and mine plan, utilizing an average cut-off grade of 0.679% Nb2O5 with an NSR of US$ 180/mt.\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) average production rate of ~7,450 tonnes of FeNb/annum in the years of full production,\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.",

The financial model was run post-February 2019, which reflects a total cost per tonne of US$ 196.72 versus US$ 189.91 (May 20, 2022 Mineral Reserve Details Table above). This is not considered a material change.\nPrice variances for commodities are based on updated independent market studies versus earlier projected pricing. The updated independent market studies do not have a negative effect on the reserve.",
