Fronteer Development Group Inc. (FRG- TSX/NYSE Amex) is pleased to announce that Newmont USA Limited ("Newmont"), a subsidiary of Newmont Mining Corporation, has provided the results from a further nine holes recently drilled as part of their 2009 US$5M work-program at the Sandman gold project in Nevada. 

Six holes intersected near-surface, oxide gold mineralization within the Southeast Pediment deposit, continuing to demonstrate the high-grade nature of this emerging deposit.

Highlights include:

• 25.58 grams per tonne gold  over 5.28 metres, including 65.69 g/t over 1.95 metres in NSM-53;
• 120.75 g/t over 1.95 metres in NSM-69; and,
•  20.21 g/t over 1.98 metres in NSM-76.

Three holes also tested the Silica Ridge deposit, located five kilometres from Southeast Pediment.  Results were encouraging with the highest gold reported as 3.57 g/t over 1.34 metres in NSM-102. 

Phase 1 of the 2009 development and exploration program came to close on April 17, with a total of 62 holes and 6,700 metres drilled since January 2009.  Newmont plans to compile data for the next two months and resume drilling in mid-July. 

Newmont's 2009 work-program will provide the foundation for ongoing development activities. The overall objectives of the 2009 development program are to focus on the known deposits at SE Pediment and Silica Ridge and drill a combination of HQ and PQ core holes to:

The 2009 exploration program will focus on finding additional mineralization along the known structural trends from two of the four existing gold resource areas, and also target new areas generated from geological mapping and the results of recent geophysical and geochemical surveys. 

At Sandman, high-grade, gold mineralization occurs in multiple locations along a 16-kilometre trend, situated within the regional King River Rift structure. High-grade vein-related gold systems, including the Sleeper gold mine and the Goldbanks deposit, also occur along the King River Rift, suggesting regional structural control that could expand the size and continuity of the mineralization at this project. 

Sandman's deposits are near-surface and potentially amenable to open-pit mining. Infrastructure surrounding Fronteer's Sandman project is considered excellent. The property is within trucking distance 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. 

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 US$14 million on exploration and development, making a commitment to fund and construct a mine, and completing a feasibility study. Newmont has met all earn-in obligations to date.

SANDMAN DRILL RESULTS

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 gold and 2.0 g/t gold for the higher grade internal intervals.

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 QA-QC 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.
