Disclosure of operating segments [abstract] |
SEGMENTED INFORMATION | Business Segments The Company operates in three primary segments – the Mining segment, the Closed Mine Services segment and the Corporate and Other segment. The Mining segment includes activities related to exploration, evaluation and development, mining, milling (including toll milling) and the sale of mineral concentrates. The Closed Mine Services segment includes the results of the Company’s environmental services business which provides mine decommissioning and other services to third parties. The Corporate and Other segment includes management fee income earned from UPC and general corporate expenses not allocated to the other segments. Management fee income has been included in the same segment as general corporate expenses due to the shared infrastructure between the two activities. For the year ended December 31, 2020, reportable segment results were as follows:

Revenue Concentration The Company’s business is such that, at any given time, it sells its environmental and other services to a relatively small number of customers. During 2020, one customer from the corporate and other segment, three customers from the Closed Mines Group segment and one customer from the mining segment accounted for approximately 94% of total revenues consisting of 18%, 57% and 19% respectively. During 2019, one customer from the Corporate and Other segment, three customers from the Closed Mine Services segment and one customer from the Mining segment accounted for approximately 99% of total revenues consisting of 13%, 56% and 30% respectively. Revenue Commitments Denison’s revenue portfolio consists of short and long-term sales commitments. The following table summarizes the expected future revenue, by segment, based on the customer contract commitments and information that exists as at December 31, 2020:

The amounts in the table above represent the estimated consideration that Denison will be entitled to receive when it satisfies the remaining performance obligations in its customer contracts. Various assumptions, consistent with past experience, have been made where the quantity of the performance obligation may vary. In addition to the amounts disclosed above, the Company is also contracted to pay onward to APG all toll milling cash proceeds received from the MLJV related to the processing of specified Cigar Lake ore through the McClean Lake mill (see note 11). The timing and amount of such future toll milling cash proceeds are outside the control of the Company.
