Fronteer Development Group Inc. ("Fronteer" or the "Company") (FRG - TSX/AMEX) is pleased to announce that further step-out drilling has extended high-grade, near-surface, oxide gold mineralization by an additional 100 metres (328 feet) along strike at its 51% owned Long Canyon project in Nevada.

To date, Long Canyon's 2008 work-program has extended mineralization along strike to 1.7 kilometres (1.1 miles) and across multiple zones, with a footprint up to 400 metres (1,300 feet) in width. Mineralization remains open in all directions.

Two 100-metre step-out holes returned: 

• 3.12 grams per tonne gold  (0.091 ounces per ton) over 24.4 metres (80 feet), including 9.87 g/t (0.288 oz/ton) over 3.0 metres (10 feet), in hole LC149;
• 3.01 g/t  (0.088 oz/ton) over 7.6 metres (25 feet), including 5.92 g/t (0.173 oz/ton) over 1.5  metres (5 feet), in LC147.

Other new results continue to further define this growing deposit, demonstrating encouraging consistency and continuity of grade, including:

• 4.81 g/t  (0.141 oz/ton) over 12.8 metres (42.2 feet), including 8.16 g/t (0.238 oz/ton) over 4.3 metres (14.1 feet), in LC107C;
• 4.95 g/t (0.145 oz/ton) over 13.8 metres (45 feet), including 8.52 g/t (0.249 oz/ton) over 6.1 metres (20 feet), in LC141.

Approximately 21,200 metres (69,700 feet) of drilling from more than 130 holes have been completed at Long Canyon this year. Two reverse circulation rigs and two Diamond drill-core rigs are currently turning on site. Results are pending from approximately 70 drilled holes, with an additional 20 holes planned for the season. 

The remainder of the 2008 work program is focusing on:

• infill drilling between the northeast extensions and the rest of the drill grid; 
• extending mineralization in the Shadow Zone, a new parallel zone of mineralization; and,
• infill drilling selected areas of the southern portion of the deposit.

A project-first NI 43-101 resource estimate is planned by the end of January 2009. 

Mineralization at Long Canyon is sediment-hosted and associated with solution breccias and stratabound horizons along a boudinaged limestone-dolomite contact. With drilling consistently intersecting near-surface, high-grade oxide gold mineralization, Long Canyon is developing into a high-quality gold deposit. 

Fronteer is majority owner (51%) and manager of Long Canyon through a participating joint venture with AuEx Ventures Inc. ("AuEx") (49%).  An initial joint venture project budget of approximately US$3.9 million will see activities through to March 2009. 

Long Canyon, Sandman and Northumberland are currently Fronteer's leading properties among its large, portfolio of gold projects 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 emerging 400,000-acre Eastern Great Basin portfolio.

LONG CANYON DRILL RESULTS

True widths of the mineralized intervals are interpreted to be between 70-100% of the reported lengths. Results less than 1 g/t not highlighted in this table.  Holes LC144-45 and LC150-152 had no reportable intercepts.

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. Reverse circulation cuttings were sampled on 5.0 feet (1.52 metre) intervals and core was sampled at geologically selected intervals.  All drill samples were assayed by 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 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.
