Fronteer Development Group Inc. (FRG - TSX/NYSE Amex) announces today that drilling has intersected wide intervals of mineralization from an emerging gold zone at its 51%-owned and operated Long Canyon gold deposit in northeastern Nevada.

Newly reported drill results reinforce strong continuity of gold mineralization at the Shadow Zone, a 2008 discovery located immediately northwest of the main Discovery Zone. Highlights from the Shadow Zone include:

• 1.31 grams per tonne gold (0.038 ounces per ton) over 51.8 metres, including 9.30 g/t (0.270 oz/ton) over 1.9 metres in LC249C; and
• 1.23 g/t (0.036 oz/ton) over 46.0 metres in LC245C.

Results from additional metallurgical holes also continue to showcase the high-grade nature of gold mineralization at Long Canyon. Highlights include:

• 7.94 g/t (0.232 oz/ton) over 19.2 metres, including 20.3 g/t (0.593 oz/ton) over 6.7 metres in LCM2;
• 4.25 g/t (0.124 oz/ton) over 29.0 metres, including 8.14 g/t (0.238 oz/ton) over 12.2 metres in LCM8; and
•  2.86 g/t (0.083 oz/ton) over 11.0 metres, including 11.0 g/t  (0.321 oz/ton) over 1.3 metres in LCM1.

The Long Canyon joint venture recently purchased a total of 11,805 acres of surface rights and 1,657 acre feet per year of water rights in an area located east of the project site for US$4,262,000.

Outside of the Long Canyon joint venture, Fronteer owns more than 400,000 acres of mineral rights in northeast Nevada. Long Canyon, Sandman and Northumberland are Fronteer's most advanced U.S.-based gold projects and comprise the Company's future production platform in Nevada.

Moira Smith, Ph.D., and Professional Geologist as recognized by the Association of Professional Engineers and Geoscientists, British Columbia, 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. 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 for gold by Fire Assay of a 30 gram (1 assay ton) charge with an AA finish, or if over 5.0 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.
