Cameco Annual Report 2011

Exploration

Exploration is key to ensuring our long-term growth, and since 2007 we have more than doubled our annual investment.

2011 update

Brownfield exploration

Brownfield exploration is uranium exploration near our existing operations, and includes expenses for advanced exploration projects where uranium mineralization is being defined.

This year we spent $10 million on five brownfield exploration projects, and $38 million for resource definition at Kintyre and at Cigar Lake.

Regional exploration

We spent about $48 million on regional exploration programs (including support costs). Saskatchewan was the largest region, followed by Australia, northern Canada, Asia and South America.

Plans for 2012

We plan to spend approximately $115 million on uranium exploration in 2012 as part of our long-term strategy.

Brownfield exploration

We plan to spend approximately $15 million on five brownfield exploration projects in the Athabasca Basin and Australia. Our expenditures on projects under evaluation are expected to total $35 million, with the largest amounts spent on Kintyre and Inkai block 3.

Regional exploration

We plan to spend about $65 million on 49 projects worldwide, the majority of which are at drill target stage. Among the larger expenditures planned are $9 million on two adjacent projects in Nunavut, $9 million to test targets near our US operations and on our satellite properties, $4 million on the Read Lake project, $5 million on targets in South Australia, and $5 million to follow up encouraging results on the Wellington Range project in Australia.
