Fronteer Development Group Inc.: Preliminary Economic Assessment for Long Canyon Project Generates 64% IRR

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 1, 2009) - Fronteer Development Group Inc. (TSX:FRG)(NYSE Amex:FRG) is pleased to announce the completion of Long Canyon's first Preliminary Economic Assessment (PEA). The PEA is based on the project's March 2009 resource estimate and does not include the approximately 30,000 metres of subsequent drilling completed this year. Long Canyon's initial PEA illustrates that the project is viable in today's cost environment and has a solid economic foundation to build upon.

The study, prepared by Mine Development Associates (MDA) of Reno, Nevada, and reviewed by AMEC Americas Limited, is based on an Indicated Mineral Resource of 4.8 million tonnes grading 2.4 g/t gold (363,000 gold ounces) and an Inferred Mineral Resource of 8.8 million tonnes grading 1.6 g/t gold (459,000 gold ounces) at a cutoff grade of 0.3 g/t gold. The PEA supports a financially robust open-pit, run-of-mine (ROM), heap-leach operation. At a 5% discount rate, and US$800/oz gold price, the project's pre-tax net present value (NPV) is US$145 million with a pre-tax internal rate of return (IRR) of 64% on an unleveraged 100% equity basis, and a pay-back period of 1.3 years.

"This PEA confirms our view that Long Canyon is a straightforward project amenable to conventional, low-cost mining and extraction methods, the simplicity of which could shorten our lead time to production," says Troy Fierro, Fronteer Chief Operating Officer. "In a short period of time, this asset has become a viable project, with mineralization open in every direction."

All dollar amounts in this release are stated in US currency. The disclosure set forth below is derived from the PEA unless otherwise expressly noted.

Note: This PEA is preliminary in nature as it includes inferred mineral
resources that are considered too speculative geologically to have the
economic considerations applied to them that would enable them to be
categorized as mineral reserves at this time and as such there is no
certainty that the preliminary assessment and economics set forth in
the PEA will be realized. Mineral resources that are not mineral
reserves do not have demonstrated economic viability.

In management's view, such favourable economics at this early stage of project development provide a strong incentive for continued exploration, resource expansion and aggressive development. The results of this year's exploration/development program will be incorporated into an updated resource estimate in Q1 2010, followed by a revised economic analysis.

Fronteer believes there are excellent opportunities to refine various project elements and improve the economics through cost reduction and optimization, as outlined in the PEA.


The Long Canyon property is controlled by a joint venture, of which Fronteer (51%) is majority owner and operator. Fronteer also has a 3% net smelter return (NSR) royalty on gold ounces produced from mineral lands that it contributed to the joint venture. Approximately 84% of the ounces produced in the PEA model are attributable to this Fronteer NSR royalty.

The construction phase of the Long Canyon Project is anticipated to take approximately one year. Processing facilities will be located near the leach pad. Most of the buildings, including maintenance facilities, office and warehouse, would also be located at the mine site.


The PEA considers development of the Long Canyon project as an open-pit mine and ROM heap-leach operation. The pit is developed in five phases designed to provide sufficient ore for leaching and exploitation of Whittle pit shells that maximize the NPV of the deposit. Material grading better than the internal cut-off grade of 0.22 g/t gold was considered for open-pit mining.

The forecast mine life is six years, during which time 9.4 million tonnes of ore will be mined and placed on the leach pad and 81.3 million tonnes of waste will be trucked to a waste dump. Throughout the life-of-mine, an estimated 565,000 ounces are produced at an average grade of 2.15 g/t gold. Better than average grades and more than 100,000 ounces per year are recovered in years 1, 2 and 5, with peak production of 131,000 and 132,000 ounces per year in years 2 and 5.

All mineralized material classified as Indicated and Inferred Mineral Resources was considered in the optimization and mine plan.


The metallurgical component of the PEA was supervised by G.L. Simmons and supported by work carried out by McClelland Laboratories in Nevada. Gold production was estimated based on ultimate recovery and lagged recovery on an annual basis. Ultimate recoveries used are 88% and 80% for material grading above and below 1.25 g/t gold, respectively. Total gold recovery from the leach pads averaged 87% during the life-of-mine.


The PEA outlines the project's infrastructure and building requirements, which will include a single-use leach pad, carbon columns and electrowinning circuits, water wells, a waste-rock dump, access and haul roads, office buildings, shop & warehouse, and explosives magazine. A 69 KV power transmission line must also be built connecting the mine site to existing power north of the mine.


The initial project capital costs of the Long Canyon project are estimated to be $66.0 million, primarily based on mining equipment and infrastructure. Sustaining capital through the life of mine would be an additional $6.0 million, which would be derived from cash flow and primarily (approx. 75%) used for leach-pad expansions.


The following life-of-mine costs are expected for the operating phase of the project:

Items Cost per tonne processed Cost per ounce
Mining cost $15.58 $259.52
Processing and refining cost $ 2.12 $ 36.81
G&A (transport included) $ 2.57 $ 42.76
Reclamation $ 0.71 $ 11.78


The following sensitivity table demonstrates that the project has robust economics across a range of gold-price scenarios.

Gold price IRR (pre-tax) NPV (5%, pre-tax) Pay back
$700 45% $ 96 million 1.5 years
$800 (base case) 64% $144 million 1.3 years
$900 82% $193 million 1.1 years
$1000 100% $241 million 1.0 years


Fronteer's 2009 exploration/development work-plan includes recently completed infill and step-out drilling, as well as ongoing engineering, environmental, hydrological, metallurgical, land and legal programs. Subsequent work activities will lead to continued refinement of project input parameters in the following areas:

- Resources: Resource expansion represents the most significant opportunity for enhancing project economics. Additional delineation and infill drilling will increase the confidence of resource estimates. This will enable conversion of resources from Inferred to Measured and Indicated categories, which will in turn provide for a higher conversion rate of resources to reserves.

- Geotechnical: On-going geotechnical studies will provide slope parameters for pit designs to ensure safe and optimal pit walls.

- Processing: Ongoing metallurgical testing of materials representative of the deposit needs to be completed to confirm recoveries; preliminary metallurgical testing relied on near-surface samples. Metallurgical findings from composites taken from three cross-sections are expected to be reported during Q1 2010.

- Permitting: Permitting strategies are currently being developed and all baseline data are being collected to support permit submission.

Long Canyon mineral resource estimation as of February 9, 2009. The Long Canyon mineral resource estimation was completed by MDA. The resources were modelled and estimated by evaluating the drill data statistically and utilizing three-dimensional lithologic solids provided by Fronteer to interpret mineral domains on cross sections spaced at 50-metre intervals throughout the extent of the Long Canyon mineralization. The mineral domain interpretations were then rectified on cross sections spaced at 10-metre intervals. The modeled mineralization was analyzed statistically to establish estimation parameters, and gold grades were estimated by inverse-distance methods into a block model with 5 metre (width) x 10 metre (length) x 3 metre (height) blocks that were coded to the mineral domains by the 10-metre mineral domain polygons. All modelling of the diluted resources was performed using Gemcom Surpac® software. Quality-control data generated during the various drill programs conducted at Long Canyon were independently reviewed by MDA as part of the resource study. The person responsible for the resource estimate on behalf of MDA is Michael Gustin, Ph.D., P. Geo, a Qualified Person as defined by National Instrument 43-101. Further details of the estimation procedure are available in the updated NI 43-101 report posted on SEDAR (
