TORONTO, Feb. 27, 2014 (GLOBE NEWSWIRE) -- Carlisle Goldfields Limited (TSX:CGJ) ("Carlisle" or the "Company") is pleased to announce that it has received the results of an optimized NI 43-101 compliant Preliminary Economic Assessment ("PEA") of the Farley and MacLellan gold deposits at the Company's Lynn Lake Gold Camp project ("Lynn Lake") in Manitoba, Canada. The results of the PEA include a post-tax Net Present Value ("NPV") at a 5% discount rate of $257 million with a post-tax Internal Rate of Return ("IRR") of 26% on initial capital costs of $185 million including contingencies. Carlisle engaged Tetra Tech to complete the optimized PEA.
Highlights from the PEA, with the base case gold ("Au") price of US$1100 per ounce ("oz"), $18.33/oz Silver ("Ag") price and $0.90 Exchange Rate ("Fx") are as follows (all figures are in Canadian Dollars unless otherwise stated):
|-- NPV at 5% of $411 million||-- NPV at 5% of $257 million|
|-- IRR of 34%||-- IRR of 26%|
|-- Net cash flow of $642 million||-- Net cash flow of $422 million|
|-- Payback period of 2.6 years||-- payback of 2.8 years|
- Initial capital costs of $185 million, which includes $35 million in contingency costs
- Annual average mill production of 145,000 oz Au with a peak of 230,000 oz in the 5th year
- Pre-tax total average (C1) Life of Mine ("LOM") cost of $530 per oz Au and all-in sustaining costs of $ per oz Au (both are net of silver ("Ag") by-product credits) (?)
- LOM Au production of 1.74 million oz and 1.59 million oz of silver
- LOM average head grade of 2.2 g/t Au
- Central milling facilities with a with an initial milling capacity of 3,750 tonnes per day ("tpd") in years 1-4 and ramping to full capacity of 7,500 tpd in year 5 of a 12 year mine life sequenced between the Farley and MacLellan open pit deposits
- At US$1300 Au, the post-tax NPV rises to $400 million with a post-tax IRR of 35%. (using US$21/oz Ag, $0.92 Fx)
Abraham Drost, President and CEO of Carlisle states that, "Carlisle's project at Lynn Lake meets the challenge of a US$1100 gold price base case recently adopted by a senior gold mining company and credit rating agency in the sector. The optimized PEA demonstrates compelling economic viability with some of the lowest-decile proforma capital and operating costs in the sector. The study features a sequenced open pit mining model between the Farley and MacLellan deposits at Carlisle's Lynn Lake Gold Camp and verifies a deep value proposition for Carlisle shareholders with an initial capital cost approximately $90 million lower than that of the original 10,000 tpd PEA. With the optimized PEA in place at a base case gold price of US$1100, the Company demonstrates the inherent strength and long term viability of the Lynn Lake gold camp project at current or lower gold price levels in mining-friendly Manitoba (Table 1)."

1. CIM definitions were followed for estimating mineral resource.
2. Assumed mining dilution rate 5%.
3. Mineral Resources are estimated using a diluted cut-off grade (AU Equiv.)
4. Mineral Resources are estimated using a gold price of US$1,241/oz, and a Silver price US$20/oz.
5. Mineral Resources are estimated using a gold recovery rate 89.3% and 93.7% for MacLellan and Farley separately.
6. Mineral Resources are estimated using a silver recovery rate 61% for MacLellan only.
7. There are no known risks that could materially affect potential development.

Capital and Operating Costs
The total estimated initial capital costs for development of the Farley and MacLellan deposits at the Lynn Lake Gold Camp is $185 million, which includes a 23% contingency allowance of approximately $35 million. Graph 1 shows the annual production and associated operating costs per oz for each year over the LOM. Graph 2 highlights the comparison of operating cost vs. gross revenues (excluding processing costs and royalty costs).

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.
Mike McLaughlin, P.Eng. is a Principal Project Manager and Mine Engineer of Tetra Tech and conducted the PEA Project management. He is a Qualified Person under the requirements of NI 43-101 and has reviewed the technical content of this press release and approved its dissemination.
Rick Adams, P.Eng., Chief Operating Officer and Peter Karelse, P.Geo., VP Exploration of Carlisle are Qualified Persons under the terms of NI 43-101 and have reviewed the technical content of this press release on behalf of the Company and approved its dissemination.
