Fronteer Development Group Inc. (FRG - TSX/NYSE Amex) is pleased to announce the details of a US$14.1-million, joint-venture funded exploration program at its 51%-owned and operated Long Canyon gold project in northeastern Nevada.

The 2009 work-program will build on the strong geological foundation established in 2008, with a clear focus on both increasing the deposit size and better understanding the scope of potential development scenarios. Fieldwork for the program will commence in early May.

Approximately US$10 million will be spent on expansion and infill drilling, with 35,000 metres of RC and core drilling planned. The balance of the budget will be spent on preliminary environmental, engineering and metallurgical studies to begin assessing potential processing options and economics of the deposit.

"Based on the project’s first resource estimate, it is clear that Long Canyon shows encouraging economic potential and has excellent opportunities for continued resource growth over the coming year," says Dr. Mark O’Dea, Fronteer President and CEO.

The Long Canyon resource is 100% oxide and characterized by wide intervals of at- or near-surface, high-grade, gold mineralization and remains open in all directions, including to depth.

Long Canyon recently reported its first resource estimate (See March 13, 2009 press release). The grade-tonnage distribution of this estimate shows that higher cut-off grades only modestly reduce the number of contained ounces, while significantly increasing the average grade of the resource.

REMAINING 2008 DRILL HIGHLIGHTS
Highlights of the final 52 unreported holes from last year’s 24,700-metre (164-hole) work program, which are included in the recently announced resource estimate, are reported below.

True widths of the mineralized intervals range from 70-100% of the reported lengths. The Classified Mineral Resource estimate comprises a cut-off grade of 0.30 g/t gold. Results less than 1 g/t not reported in this highlights table. For a table showing comprehensive drill results, please click: http://www.fronteergroup.com/sites/f... Results include new, additional intercepts from previously reported holes LC146C, 148C, 160C, and 164C. Drill hole ID numbers ending with a "C" in the table indicate core holes with all others being reverse circulation holes.

Long Canyon, Sandman and Northumberland are Fronteer's leading gold properties in Nevada. Long Canyon, located 6.5 km (4 miles) south of the I-80 Freeway corridor in northeastern Nevada, is part of Fronteer's 400,000-acre Eastern Great Basin portfolio.

Robert Felder, M.Sc. and Certified Professional Geologist, as recognized by the American Institute of Professional Geologists, is designated as a Qualified Person for these Long Canyon drill results, with the ability and authority to verify the authenticity of, and validity of, this data. Drill composites were calculated using a cut-off of 0.30 g/t. Drill intersections are reported as drilled thicknesses and not corrected for true width. Reverse circulation cuttings were sampled on 5.0 feet (1.52 metre) intervals and core was sampled at geologically selected intervals. Drill samples were assayed by ALS Chemex (ISO9001:2000) in Reno, Nevada, or American Assay Laboratories (ISO9002:2002) in Sparks, Nevada, for gold by Fire Assay of a 30 gram (1 assay ton) charge with an AA finish, or if over 10.0 g/t were re-assayed and completed with a gravimetric finish. For these samples, the gravimetric data were utilized in calculating gold intersections. QA/QC included the insertion and continual monitoring of numerous standards and blanks into the sample stream, and the collection of duplicate samples at random intervals within each batch. Selected holes are also analyzed for a 72-element geochemical suite by ICP-MS.

Long Canyon mineral resource estimation as of February 9, 2009. The Long Canyon mineral resource estimation was completed by Mine Development Associates ("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 will be available in an updated NI 43-101 report, which will be posted on SEDAR (http://www.sedar.com/), no later than 45 days from the date of the March 13, 2009, release.
