Bruce Reid, President and CEO of Carlisle states that, "We are pleased that this positive PEA demonstrates the potential economic viability of Carlisle's Lynn Lake Gold Camp and shows a deep value proposition for Carlisle shareholders. The current PEA demonstrates the longer term development potential of a sequenced pro-forma mine plan for the four known open pit gold and gold-silver deposits controlled by Carlisle at Lynn Lake. The Company will now immediately focus on further PEA level assessment of an optimized initial mine development scenario involving only the two higher grade and more advanced deposits, the MacLellan Mine Project and the Farley Lake Mine Project (Table 1).

The PEA Technical Report will be filed on SEDAR within 45 days of this news release. The information presented summarizes the results of the PEA for a mine and processing scenario based on an NI 43-101 compliant mineral resource estimate prepared by P&E Mining consultants which includes assay data up to May 1, 2013.
The PEA was prepared by Tetra Tech in accordance with the standards of NI 43-101. The PEA is considered preliminary in nature. It includes inferred mineral resource estimates that are too speculative to have the economic considerations applied that would enable classifications as mineral reserves. There is no certainty that the conclusions within the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
