Shallow Drilling Demonstrates High-Grade Nature of Mineralization at Sandman Gold Project

Fronteer Development Group Inc. ("Fronteer" or the "Company") (TSX: FRG)(NYSE-A: FRG) is pleased to announce that drilling by Newmont Mining Corp. ("Newmont") continues to delineate near-surface, high-grade, oxide gold mineralization at the Sandman gold project in Nevada.

Newmont has provided Fronteer with assay results for the first 16 holes drilled in Sandman's Southeast Pediment deposit. A total of 37 holes were completed at Sandman during the 2008 program. Assays for the remaining 21 holes are pending. Similar to Fronteer's Long Canyon project, drill results feature consistent, wide intervals of gold mineralization with high-grade zones, including:

- 2.58 grams per tonne gold (0.075 ounces per ton) over 26.19 metres, including 25.78 g/t (0.752 oz/ton) over 1.68 metres, in NSM-04;

- 2.24 g/t gold (0.065 oz/ton) over 11.68 metres, including 12.08 g/t (0.352 oz/ton) over 1.59 metres, in NSM-08; and

- 2.05 g/t (0.060 oz/ton) over 13.57 metres, including 19.96 g/t (0.582 oz/ton) over 0.95 metres, in NSM-19; along with,

- Silver grades as high as 74.44 g/t (2.17 oz/ton).

Sandman currently includes a group of four closely spaced deposits that are near-surface and potentially amenable to open-pit mining, with resource expansion and exploration upside potential. Sandman is located along trend of the Sleeper gold mine and Goldbanks deposit, along the King River Rift that hosts multiple high-grade vein gold systems. Infrastructure surrounding Fronteer's Sandman project is excellent. The property is close to Newmont's Twin Creeks mine, potentially eliminating the need for a stand-alone milling facility and other significant capital expenditures if the project were to proceed to production.

Sandman's exploration and development program is focused on:

1. Confirming the character of near surface gold mineralization at Sandman's Silica Ridge and SE Pediment deposits;

2. Obtaining bulk metallurgical material for mill grade and heap leach metallurgical tests; and,

3. Deepening the understanding of the geology and controls on gold mineralization.

Under the terms of the Sandman option and joint-venture agreement, Newmont can earn an initial 51% interest in the project by making a positive production decision by June 2011, spending a minimum of $14 million on exploration and development, making a commitment to fund and construct a mine, and completing a bankable feasibility study.

Note: The true width of the mineralized zones is estimated to be
approximately 90% of those stated. Primary composite intervals were
calculated using a cut-off of 0.5 g/t Au, and 2.0 g/t Au for the higher
grade internal intervals.

Since signing the option deal in June 2008, Newmont has completed 2,800 metres (9,300 feet) of drilling in 37 core holes. Over the next few months, a 2009 drilling program will be determined to cover additional development drilling at Sandman and initiate a series of exploration drill holes which will cover various property wide target areas based on surface mapping, geophysical and soil sampling results.

Sandman, Northumberland and Long Canyon are currently Fronteer's leading properties among its large portfolio of gold projects in Nevada. For more information on Sandman and Fronteer's other Nevada projects, visit: http://www.fronteergroup.com/?q=content/nevada.

Drill samples and analytical data for the Sandman project are being collected under the supervision of Newmont, Fronteer's joint venture partner and project operator, using industry standard QAQC protocols. Fronteer's James Ashton P.E., who is the QP responsible for compiling the data contained in this release, has not verified the data; however, the grades and widths reported here agree well with the Company's past results on the project and correspondence with the operator has given him no reason to doubt their authenticity. For further details on Sandman, please view the technical report prepared by Mine Development Associates ("MDA"), as of May 31, 2007, on SEDAR at http://www.sedar.com.

LIQUIDITY
