Subsequent Events	SUBSEQUENT EVENTS Alta Mesa Divestiture On February 14, 2023, the Company closed on its sale of three wholly owned subsidiaries that together hold Energy Fuels’ Alta Mesa ISR Project to enCore Energy (“enCore”) for total consideration of $120 million, paid as follows: a.$60 million cash at or prior closing; and b.$60 million in a secured convertible note (the “Note”), payable in two years from the closing, bearing annual interest of eight percent (8%). The Note is convertible at Energy Fuels’ election into enCore common shares at a conversion price of $2.9103 per share, being a 20% premium to the 10-day volume-weighted average price of enCore shares ending the day before the Closing. enCore is currently traded on the TSXV and NYSE American. The Note is guaranteed by enCore Energy Corp. and fully secured by Alta Mesa. Unless a block trade or similar distribution is executed by Energy Fuels to sell the enCore common shares received on conversion of the Note, Energy Fuels will be limited to converting the Note into a maximum of $10 million principal amount of the Note per thirty (30)-day period. In addition, enCore is required to replace the existing reclamation bonds for the Alta Mesa project shortly after the closing of the transaction, which will result in Energy Fuels receiving an additional $3.6 million cash as a return of collateral from those bonds. Bahia Project On February 10, 2023, the Company completed its previously announced acquisition of the Bahia Project (the “Bahia Closing”). The Bahia Closing followed the Brazilian Government’s approval of the transfers to Energy Fuels’ wholly owned Brazilian subsidiary Energy Fuels Brazil, Ltda. At the Bahia Closing, the Company paid the mineral owners the remaining $21.9 million cash.
