TORONTO, ONTARIO -- (Marketwire) -- 03/07/13 -- Carlisle Goldfields Limited ("Carlisle" or the "Company") (TSX: CGJ)(OTCQX: CGJCF) is pleased to announce that it has successfully reached an agreement to extend its option to acquire the Last Hope Project for an additional term of three years (to December 31, 2015).

Carlisle's President and CEO, Bruce Reid commented that: "We are pleased that we were able to extend our option on the Last Hope Project.

1. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

2. The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to the Indicated or Measured mineral resource category.

3. The mineral resources in this press release were estimated using the inverse cubed grade interpolation method and the CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions adopted by CIM Council.

4. The gold price used was the February 28, 2013 two-year trailing average of US$1,643/oz with a process recovery of 95%. The US$ exchange rate was $1.00.

5. Process costs used were C$15/tonne and G&A was C$5/tonne. Underground mining costs were C$80/tonne.

6. The Company's initial resource estimate used a 2.0 g/t cut-off grade.

Under the terms of the extension to the option agreement, Carlisle has agreed to incur an aggregate of $2,000,000 of exploration expenditures on or before December 31, 2015 (of which more than $1,000,000 has already been incurred), make three interim cash payments of $100,000 each on or before January 31, 2013, December 31, 2013 and December 31, 2014 and a final cash payment of $2,000,000 on or before December 31, 2015. The vendor has reserved a net smelter return royalty of 2.5% of which one half may be purchased for $1,250,000 to reduce the royalty to 1.25%.

The Last Hope Project is located approximately 20 kms southeast of Lynn Lake, Manitoba and 8 km south of Carlisle's Burnt Timber and Linkwood Projects. Last Hope had previously been substantially explored and drilled (1982-1984). In addition to drilling completed during 2012, the resource estimate was determined utilizing assays of over 200 historical diamond drill holes in the mineralized zones. The core from this historical drilling remains intact at the project site and was partially re-assayed last year.

The Last Hope Project estimate is the fourth NI 43-101 compliant technical report on a resource estimate that Carlisle has produced in less than a year. See below in "About Carlisle" or on for Carlisle's news releases dated March 13th, 2012, September 24th 2012 and January 15, 2013. Management expects to complete a fifth NI 43-101 compliant technical report on its Farley Lake Project before the end of the second quarter of 2013.


The mineral resource estimate on the Last Hope Project was undertaken by P&E Mining Consultants Inc. ("P&E") for Carlisle under the supervision of Eugene Puritch, P.Eng., President of P&E, who is a Qualified Person as defined by NI 43-101 with more than 30 years of experience in exploration and development of gold projects.

Carlisle's exploration programs are carried out under the supervision of Peter Karelse P.Geo., Vice-President of Exploration, who is also a Qualified Person as defined by NI 43-101 with more than 30 years of experience in gold exploration and development.

Samples were transported directly in secure containers from the Carlisle Goldfields site in Lynn Lake Manitoba, to the TSL Laboratories in Saskatoon, Saskatchewan. TSL, which is an accredited ISO/IEC 17025 lab, assayed the samples using standard fire assay methods with a gravimetric finish. Certified standards are placed in the sample stream at a rate of one standard per 20 samples. Certified blanks are placed in the sample stream at a rate of one blank every 40 samples.

All technical information contained in this news release has been reviewed and approved by Peter Karelse, P.Geo. and Eugene Puritch, P.Eng. of P&E, both Qualified Persons as defined under NI 43-101.
