  JANUARY 25, 2001 - 16:31 EST
                 TORONTO, ONTARIO--Denison Mines Limited announced today that the                 loan agreement with Cogema Resources Inc. has been amended. The                 amendments provide for an extension of the term of the loan                 facility from December 31, 2002 to December 31, 2005, which is                 further extended to December 31, 2010 if a production decision on                 the Midwest project has been taken prior to the end of 2005. At                 the expiry of the term, the loan balance must be reduced by 20%                 per year and interest payments made monthly. 
                 As part of this agreement, Denison has the right to prepay any                 amount and redraw on 45 days' notice all such prepayments together                with the interest, at bank prime plus 1%, not incurred as a result                of all such prepayments. Denison prepaid $12 million in November                 2000 as part of interim arrangements pending completion of the                 detailed amendments and thereby reduced the Company's interest                 costs while at the same time maintaining its access to these funds                as it may require. The loan balance will be approximately $53                 million on January 31, 2001 after applying receipts from all                 fourth quarter uranium sales. 
                 Denison is also pleased to announce that it has executed an                 agreement for Denison Environmental Services to perform all the                 services for the five closed mine sites of Rio Algom in Elliot                 Lake, Ontario. The agreement has an initial term of five years and                includes all monitoring, effluent treatment, maintenance, data                 storage and reporting activities associated with the five closed                 mine sites. 
                 In Saskatchewan, the first oil well drilled in which Denison has                 earned a 50% interest is producing at 5 - 20 barrels of oil per                 day from a vertical section. Consideration of completing a                 horizontal leg into the producing zone is underway. Drilling of an                exploration well in another prospect is commencing today.
