Fronteer Gold (FRG - TSX/NYSE-Amex) reports that a new resource estimate for the Long Canyon deposit shows a meaningful increase in resource size and continues to showcase the high-grade nature of this new Nevada gold deposit. 

Quoted at a cut-off grade of 0.20 grams per tonne gold, the updated Classified Mineral Resource consists of:

• A Measured and Indicated (M&I) resource of 672,000 ounces at an average grade of  1.71 g/t gold (12,240,000 tonnes) and,
• An additional Inferred resource of 552,000 ounces at an average grade of 1.65 g/t gold (10,394,000 tonnes).

The previously published 2009 resource estimate was quoted at a cut-off of 0.30 g/t gold. This updated Mineral Resource estimate is quoted at a cut-off grade of 0.20 g/t gold to be consistent with the internal cut-off defined by Long Canyon's current Preliminary Economic Assessment (see Dec. 1, 2009, press release).

Using a 0.30 g/t gold cutoff, the new resource estimate shows an 81% increase in M&I ounces and a 17% increase in Inferred ounces compared to the 2009 resource. The substantial increase in M&I ounces is attributable to the 2009 work-program's focus on infill core drilling.

 "Long Canyon has rapidly transitioned from exploration to development stage, showcasing the high-quality nature of the deposit," says Troy Fierro, Fronteer Gold Chief Operating Officer. "Results from the 2009 drilling program clearly demonstrate Long Canyon has significant growth potential. In 2010, our objectives are to continue resource expansion and complete the required metallurgical, engineering, and environmental work necessary to move Long Canyon to pre-feasibility stage and prepare the project for permitting."

The grade and tonnage of this new resource estimate is shown at various cut-off grades in the table below. 

Long Canyon 2010 resource estimate

The grade-tonnage distribution of this new estimate continues to show that higher cut-off grades dramatically increase the average grade of the resource but only modestly reduce the number of contained ounces.  Specifically, at a 1.0 g/t gold cut-off, 83% of the total resource ounces remain while the grade increases by more than 100% as follows:

• An M&I resource of 558,000 ounces at an average grade of  3.67 g/t gold (4,729,000 tonnes) and,
• An additional Inferred resource of 456,000 ounces at an average grade of 3.97 g/t gold (3,571,000 tonnes).

Fronteer Gold is majority owner (51%) and operator of Long Canyon.  A $19.8 million development and exploration program, funded 49% by our JV partner, is planned for 2010.  The program is currently underway with five rigs operating. 

Long Canyon, Northumberland and Sandman comprise Fronteer Gold's future production platform based in Nevada. All three gold deposits have high-grade gold starting at or near surface, and have encouraging production attributes.  We aim to build regional production by advancing these projects over the near-term using existing cash resources. We anticipate further deposit growth, which may add significant gold ounces to our ledger and pending results from a variety of development activities to clearly define the economic strength of our projects.

Long Canyon mineral resource estimation as of May 13, 2010. The Long Canyon mineral resource estimation was completed by Mine Development Associates ("MDA"). The resources were modeled and estimated by evaluating the drill data statistically and utilizing geologically interpreted cross-sections 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 modeling 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 will be available in an updated NI 43-101 report, which will be posted on SEDAR (www.sedar.com), no later than 45 days from the date of this release.  

Christopher Lee, P. Geo., Chief Geoscientist for Fronteer Gold, is the company's designated Qualified Person for this news release and has reviewed and validated that the information contained in the release is consistent with that provided by the independent QP responsible for the resource estimate, Michael Gustin of MDA.
