Caution Regarding Forward-Looking Information and Statements

Certain information contained in this news release constitutes "forward-looking information" or "forward-looking statements" with the meaning of Canadian and U.S. securities laws. These include our expectation that additional freezing will allow more continuous production at the mine once the mill is operational; the expected impact of temporarily stopping jet-boring on our production schedule; our expectation that our 2018 production target will not be impacted; and our plans to process ore from Cigar Lake at the McClean Lake mill. This information is based upon a number of assumptions that, while considered reasonable by management, are subject to significant uncertainties and contingencies. We have assumed that: there is no material delay or disruption in our plans as a result of ground movements, cave-ins, additional water inflows, natural phenomena, delay in acquiring critical equipment, equipment failure, labour disputes, failure to obtain or maintain regulatory approvals, or other causes; our Cigar Lake mining and production plans succeed; the McClean Lake mill is able to mill Cigar Lake ore as expected; and that any technical challenges at the Cigar Lake mine and McClean Lake mill will be resolved in a timely manner as they arise. This forward-looking information also involves known and unknown risks, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied. They include the risks that: unexpected geological, hydrological, underground condition, or ground movements and cave-ins or an additional water inflow delays or disrupts our plans; natural phenomena, labour disputes, technical challenges, equipment failure, failure to obtain or maintain regulatory approvals, delay in obtaining the required equipment or other reasons cause a material delay or disruption in our plans; our mining or production plans for Cigar Lake are delayed or do not succeed for any reason; and the plan to mill Cigar Lake ore at the McClean Lake mill is delayed or does not succeed for any reason. Please also see our most recent annual information form, annual MD&A and quarterly MD&A for other risks and assumptions relevant to the forward-looking information in this news release, including our 2018 production target. We are providing this forward-looking information to help you understand management's views regarding the status of the Cigar Lake uranium mine and it may not be appropriate for other purposes. Cameco does not undertake any obligation to update or revise forward-looking information, whether as a result of new information, future events or otherwise, except to the extent legally required.
