Fronteer Development Group Inc.: Sandman Gold Project Returns 25.58 Grams Per Tonne Gold Over 5.28 Metres

VANCOUVER, BRITISH COLUMBIA, Jun 01 (MARKET WIRE) --
Fronteer Development Group Inc. (TSX: FRG)(NYSE Amex: FRG) 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:

- confirm the character of gold mineralization (size range of the gold);

- obtain bulk metallurgical material for mill grade and potential heap
leach metallurgical tests;

- and improve the understanding of the geology and ore controls of the
mineralization.

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.

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.

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. 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.
