Cameco Announces Operational Changes in Saskatchewan and the United States

Saskatoon, Saskatchewan, Canada, April 21, 2016

Cameco (TSX: CCO; NYSE: CCJ) announced today that it is suspending production at its Rabbit Lake operation in northern Saskatchewan and production is being curtailed at Cameco Resources’ US operations by deferring wellfield development. The changes are expected to result in a reduction of about 500 positions at Rabbit Lake and about 85 at the US operations, including employees and long-term contractors.

“We regret the impact these decisions will have on many of the talented and dedicated people working at these operations and on their home communities,” said Cameco president and CEO Tim Gitzel. “Unfortunately, continued depressed market conditions do not support the operating and capital costs needed to sustain production at Rabbit Lake and the US operations. These measures will allow us to continue delivering value to Cameco’s many stakeholders and support the long-term health of our company. We will provide assistance to those affected by these decisions.”

Cameco and its US subsidiaries are working with employees at the affected operations to ensure a safe and orderly implementation of the decisions.

The Rabbit Lake operation will be placed in a safe care and maintenance state allowing Cameco the option to resume production when market conditions significantly improve. Cameco will offer affected employees exit packages. Where possible, the company will consider alternatives such as relocation to other Cameco facilities and job sharing options as part of its effort to minimize the impact on people and surrounding communities. A workforce of about 150 people will be required to maintain the facilities and sustain environmental monitoring and reclamation activities at Rabbit Lake. Work to transition the operation to care and maintenance will begin immediately and is expected to be completed by the end of August 2016. Workforce adjustments will occur over the next four months.

The US operations will continue to employ about 170 people to operate existing facilities and restore depleted wellfields, but new wellfield development will be stopped. The affected US employees will be offered exit packages with the workforce adjustments to be completed by the end of May. The US operations will continue ongoing licensing efforts to maintain the option to resume development when market conditions significantly improve.

As a result of these decisions, final production at Rabbit Lake is expected to be 1.0 million pounds in 2016 (previously 3.6 million pounds). In the US, 2016 production is expected to be 1.1 million pounds (previously 1.4 million pounds). Due to the nature of ISR (in situ recovery) mining and wellfield restoration requirements, production in the US cannot cease immediately and instead will decrease over time as head grades decline. Cameco will also review its corporate office activities in support of Rabbit Lake and the US operations with the objective of reducing general and administrative expenses.

In addition, given the current state of oversupply in the market, we have decided to reduce our 2016 production target at the McArthur River/Key Lake operation to 18 million pounds from 20 million pounds (100% basis). We will take the opportunity from additional downtime at the mill to further advance work needed to increase the mill’s production capacity for when the market signals it is needed. This includes changes to the solvent extraction circuit, bringing some ‎work on the crystallization circuit forward from 2017 and transitioning to the new calciner. There are no workforce impacts related to this change in production.

We continue to ramp up production at Cigar Lake and plan to produce 16 million pounds (100% basis) this year, subject to AREVA’s McClean Lake mill receiving the necessary regulatory approvals to increase its licensed annual production capacity from 13 million pounds to 24 million pounds.

Cameco’s annual production is now expected to be 25.7 million pounds (previously 30 million pounds).

The carrying value of Rabbit Lake is about $108 million and of the US operations is approximately $62 million (US$48 million) net of provision for reclamation. The cost of placing Rabbit Lake into care and maintenance for 2016 will be about $35 million. The expected reduction in the 2016 capital expenditures from these operational changes is approximately $48 million. The estimated severance cost is about $19 million and will be reflected in our second quarter earnings.

Keeping Rabbit Lake in a state of care and maintenance and deferring wellfield development at our US operations, rather than closing the operations permanently, gives Cameco the flexibility to increase production when market conditions significantly improve. However, with today’s oversupplied market and uncertainty as to how long these market conditions will persist, we need to focus our resources on our lowest cost assets and maintain a strong balance sheet.
