FRONTEER FINALIZES NEWMONT DEAL TO FAST-TRACK
NEVADA GOLD PROJECT TO PRODUCTION DECISION

Fronteer Development Group Inc. ("Fronteer" or the “Company”) (FRG – TSX/AMEX) is pleased to announce that it has finalized an option and joint-venture agreement with its senior Nevada partner, Newmont Mining Corporation (“Newmont”), to advance the Company’s Sandman gold project to a production decision within 36 months.

The final terms give Fronteer exposure to potential, near-term U.S. production in partnership with one of the world’s largest gold producers. Newmont may earn up to a 60% interest in Sandman by investing $23 million in advancing the project.

Infrastructure surrounding Fronteer’s Sandman project is excellent. The property is close to Newmont’s Twin Creeks mine, eliminating the need for a stand-alone milling facility and other significant capital expenditures if the project were to proceed to production.

“This deal is important to Fronteer because it maximizes Sandman’s near-term production potential by leveraging Newmont’s proven experience, expertise and nearby infrastructure,” says Fronteer President and CEO Dr. Mark O’Dea. “The agreement also frees up both our human resources and financial capital to focus on advancing our other high-priority Nevada gold projects.” Sandman, currently includes a group of five closely spaced resource areas, four of which contribute to a combined NI 43-101 resource estimate of 271,900 ounces (measured and indicated) and 38,000 ounces (inferred) gold. The deposits are near-surface and open-pit mineable, with significant resource expansion and exploration upside potential.

As part of the agreement, Newmont has also contributed over eight new sections (approximately 5,440 acres) of adjacent mineral interests to the Sandman Property, many of which have untested drill targets.

As part of Phase 2, Newmont may then earn an additional 9% interest in Sandman by spending a further US$9 million on development. Fronteer can elect to have Newmont arrange financing for its 40% of ongoing development costs at the lesser of: (i) the London Interbank Offered Rate (LIBOR) plus 4%; or (ii) Fronteer’s then current borrowing rate. Newmont shall obtain repayment of the amount advanced, plus interest, solely from up to 80% of Fronteer’s share of production, less production costs.

Provided that Newmont completes its Phase 2 earn-in requirements, Newmont shall be entitled to recover an additional sum of US$3,750,000 from 90% of the Company’s share of production (net of costs) until that amount is recovered in full.

Fronteer retains a 2% Net Smelter Return on production of the first 310,000 ounces at Sandman.

This formal agreement follows Fronteer’s recent announcement that a new resource estimate for its 100%-owned Northumberland gold project has increased the deposit’s size and advanced its production potential on multiple fronts (See June 5, 2008, press release). Northumberland, Sandman and Long Canyon are currently Fronteer’s leading properties among its large, relatively untapped portfolio of gold projects in Nevada.

Mineral resources are not mineral reserves and do not have demonstrated economic viability, and there is no guarantee that any resource will become a reserve. Michael Gustin, Ph.D., of Mine Development Associates (“MDA”), Reno, Nevada, is designated as a Qualified Person for the Sandman resource estimate, with the ability and authority to verify the authenticity of, and validity of, this data. Mineral resources have been estimated by MDA in accordance with the standards adopted by the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Council in August 2000, as amended, and prescribed by the Canadian Securities Administrators' National Instrument 43-101 Standards of Disclosure for Mineral Projects. The Sandman mineral resource expressed is based on the technical report prepared by MDA as of May 31, 2007. The cut-off grade (expressed in ounces of gold per ton) for Sandman Project measured, indicated and inferred resources is 0.01 oz Au/ton for all of the shallow deposits and 0.02 oz Au/ton for the deeper zones at the Southeast Pediment deposit. For further details on how the Sandman resource was calculated, please view the technical report on SEDAR at http://www.sedar.com/.
