Denison Reports 1999 Earnings Of $0.04 Per Share
  FEBRUARY 22, 2000
  TORONTO, ONTARIO--Denison Mines Limited today reported earnings of $12.3 million for the twelve months ended December 31, 1999  compared with a loss of $3.3 million for the year ended December  31, 1998.  Revenue was $20.5 million for the year compared to  $52.4 million in 1998.  The oil and gas portion of revenue has  declined to $3.2 million in 1999 from $22.4 million in 1998  following the closure of the Greek oil field in November 1998.   With the McClean Lake mine reaching commercial production on  November 1, 1999, the earnings from McClean Lake for November and  December have for the first time been included in income.   Shareholders' equity increased to $65.8 million from $53.4 million in 1998.   
  Results in 1999 include earnings of $13.9 million as a result of  the elimination of any Greek reclamation liability, a gain of $7.7 million from the sale of the Company's interests in the White Rose oil field and a loss of $12.9 million on account of the loss in  the Court of Appeal of the Oceanic royalty dispute.  Excluding  these items, earnings would be $3.5 million.  Results in 1998  included a $11.5 million write down of the Greek oil property. 
  In the fourth quarter of 1999, the Company reported a loss of $1.9 million primarily because of the $12.9 million loss of the Oceanic royalty decision, which was partially offset by the additional  reduction in the Greek decommissioning provision of $7.9 million.  Earnings, excluding these items, would be $3.1 million in the  fourth quarter.  Payment to Oceanic was made in January. 
  In the fourth quarter of 1999, the Company received its first U.S. $0.7 million from its Ecuador royalty and at present prices and  planned volumes expects to receive the balance of this U.S. $7.8  million royalty in 2000. 
  Production at the McClean mine averaged 81% of design capacity in  November and December 1999.  Since the year end, the mine has been operating at above nominal capacity.  Although not necessarily  representative of future results, especially in the short term,  McClean revenue in the fourth quarter was $11.4 million with  earnings of almost $1 million.  
  Denison Environmental Services had an excellent year with an  operating profit of $2.2 million.  The asset sales group alone,  sold in excess of $2.3 million in used mining equipment and  salvaged materials for the account of Denison and its customers.
