Elliot Lake reclamation trust fund The Company has the obligation to maintain its decommissioned Elliot Lake uranium mine pursuant to a Reclamation Funding Agreement effective December 21, 1995 (“Reclamation Agreement”) with the Governments of Canada and Ontario. The Reclamation Agreement, as further amended in February 1999, requires the Company to maintain funds in the reclamation trust fund equal to estimated reclamation spending for the succeeding six calendar years, less interest expected to accrue on the funds during the period. Withdrawals from this reclamation trust fund can only be made with the approval of the Governments of Canada and Ontario to fund Elliot Lake monitoring and site restoration costs. In 2023, the Company deposited an additional $864,000 into the Elliot Lake reclamation trust fund and withdrew $886,000. In 2022, the Company deposited an additional $1,199,000 into the Elliot Lake reclamation trust fund and withdrew $974,000. Letters of credit facility pledged assets At December 31, 2023, the Company has $7,972,000 on deposit with Bank of Nova Scotia (“BNS”) as pledged restricted cash and investments pursuant to its obligations under the letters of credit facility (see notes 13 and 15).
