Joint operations
Cameco conducts a portion of its exploration, development, mining and milling activities through joint operations. Operations
are governed by agreements that provide for joint control of the strategic operating, investing and financing activities among
the partners. These agreements were considered in the determination of joint control. Cameco’s significant Canadian uranium
joint operation interests are McArthur River, Key Lake and Cigar Lake. The Canadian uranium joint operations allocate
uranium production to each joint operation participant and the joint operation participant derives revenue directly from the sale
of such product. Mining and milling expenses incurred by joint operations are included in the cost of inventory.
Cameco reflects its proportionate interest in these assets and liabilities as follows:
