About U3O8 Corp.
U3O8 Corp. is focused on exploration and development of deposits of uranium and battery commodities in South America. Battery commodities that occur with uranium resources include nickel, phosphate, vanadium and zinc. The Company's mineral resources estimates were made in accordance with National Instrument 43-101, and are contained in the following deposits:

• Berlin Deposit, Colombia - a PEA shows that Berlin also has low-cost production potential due to revenue derived from multiple commodities. At current metal prices battery commodities (phosphate, vanadium, nickel and zinc) would generate the majority of revenues, followed by uranium, rare earths (yttrium and neodymium) and other metals that occur within the deposit; and
• Laguna Salada Deposit, Argentina - a PEA shows this near surface, free-digging uranium - vanadium deposit has low production-cost potential. The Company has entered into an option agreement with International Consolidated Uranium Inc. for the sale of the Laguna Salada Deposit under the terms outlined in the press release of December 14, 2020.

A PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.
