Transactions	TRANSACTIONS Joint Venture with Astron on the Donald Project On June 3, 2024, the Company executed binding agreements (collectively, the “JV Agreements”) with Astron Corporation Limited (“Astron”) creating a joint venture (the “Donald Project JV”) to jointly develop and operate the Donald Rare Earth and Mineral Sands Project in Australia (the “Donald Project”). The Donald Project is a well-known HMS and rare earth deposit that the Company believes could provide it with another near-term, low-cost, and large-scale source of monazite sand that would be transported to the Mill for the recovery of separated REE products along with the contained uranium. The Donald Project has most licenses and permits in place (or at an advanced stage of completion). The JV Agreement provides Energy Fuels the right to invest up to AUS$183 million (approximately $122 million at June 30, 2024 exchange rates) to earn up to a 49% interest in the Donald Project JV, of which approximately $10.6 million is expected to be invested in 2024 in preparation of a final investment decision (“FID”), and, if a positive FID is made, the remainder would be invested to develop the project and to earn into the full 49% interest in the Donald Project JV. In addition, the Company would issue Energy Fuels common shares (“Common Shares”) to Astron having a value of up to $17.5 million, of which $3.5 million of Common Shares would be issued in 2024 upon the satisfaction of certain conditions precedent and the remainder would be issued upon a positive FID. The Company evaluated whether the Donald Project JV is a variable interest entity (“VIE”). Variable interests can be contractual, ownership or other pecuniary interests in an entity that change with changes in the fair value of the VIE’s assets. Based on its qualitative and quantitative contractual rights under the JV Agreements, Energy Fuels has a variable interest in the Donald Project JV. Additionally, the Company has determined that it does not have a controlling financial interest in the Donald Project JV because it does not have: (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses that could potentially be significant to the VIE or the right to receive benefits that could potentially be significant to the VIE as its ownership is less than 10% of the Donald Project JV. As of June 30, 2024, the Company has elected to account for the Donald Project JV as an investment without a readily determinable fair value at cost less impairment and this investment is included in Investments on its unaudited Condensed Consolidated Balance Sheet. The Company’s maximum exposure to loss on the Donald Project JV was $2.15 million as of June 30, 2024. Changes in the design or nature of the activities of the Donald Project JV, or the Company’s involvement with the Donald Project JV, may require the Company to reconsider its conclusions on the entity’s status as a VIE and/or whether the Company is not the primary beneficiary. Planned Base Resources Acquisition On April 21, 2024, the Company announced that it had executed a definitive Scheme Implementation Deed (the “SID”) with Base Resources Limited (ASX: BSE) (AIM: BSE) (“Base Resources”) pursuant to which the Company has agreed to acquire 100% of the issued shares of Base Resources (the “Transaction”) in consideration for (i) 0.0260 Energy Fuels Common Shares (the “Share Consideration”) and (ii) AUS$0.065 in cash payable by way of special dividend by Base Resources to its shareholders (the “Cash Consideration”, and together with the Share Consideration, the “Scheme Consideration”) for each Base Resources ordinary share held, for a total value of approximately AUS$375 million at April 19, 2024. The Transaction will be effected by way of a scheme of arrangement under Australia's Corporations Act (the “Scheme”) and is anticipated to close later in 2024, subject to satisfaction of all conditions, including receipt of all necessary approvals. Base Resources owns the Toliara HMS and monazite project in Madagascar (the “Toliara Project”). The Toliara Project is a world-class, advanced-stage, low-cost, and large-scale HMS project. In addition to its stand-alone, ilmenite, rutile (titanium) and zircon (zirconium) production capability, the Toliara Project also contains large quantities of monazite sand that would be transported to the Mill for the recovery of separated REE products along with the contained uranium. The Toliara Project is subject to negotiation of fiscal terms with the Madagascar government and the receipt of certain Madagascar government approvals and actions before a current suspension on activities at the Toliara Project will be lifted and development may occur. Base Resources also owns the Kwale HMS project in Kenya, which is nearing the end of its mine life and commencement of reclamation activities.
