Fronteer Development Group Inc.: Metallurgical Drilling Returns 4.15 Grams Per Tonne Gold Over 50.8 Metres at Long

VANCOUVER, BRITISH COLUMBIA, Jun 29 (MARKET WIRE) --
Fronteer Development Group Inc. (TSX: FRG)(NYSE Amex: FRG) is pleased to
announce that it has intersected more wide intervals of high grade
mineralization and discovered an additional gold zone at its 51%-owned
and operated Long Canyon project in northeastern Nevada.

Work to date in 2009 has focused on both infill drilling for ongoing
metallurgical purposes and testing a new target located entirely outside
of the current resource area.

Metallurgical holes have been very encouraging and continue to
demonstrate the strong continuity and high-grade nature of gold
mineralization at Long Canyon. Highlights include:

- 4.15 grams per tonne gold (0.121 ounces per ton) over 50.8 metres,
including 6.98 (0.204 oz/ton) over 15.2 metres in hole LCM13;

- 3.46 g/t gold (0.101 oz/ton) over 14.9 metres, including 8.05 g/t
(0.235 oz/ton) over 2.0 metres in LCM03;

- 4.15 g/t (0.121 oz/ton) over 17.1 metres, including 7.53 g/t (0.220
oz/ton) over 6.1 metres in LCM17.

Of equal significance, drilling that tested a new target has intersected
gold mineralization over a 200-metre strike length. The new zone, called
the Syncline Zone, is located 400 metres southeast and parallel to the
Discovery Zone. Fronteer geologists developed the Syncline target through
geological modeling of the known deposit and extrapolation into other
areas. Drilling in 2009 will test additional targets located outside of
the current resource area.

Highlights from the Syncline Zone include:

- 2.95 g/t (0.086 oz/ton) over 7.6 metres, including 6.99 g/t (0.204
oz/ton) over 1.5 metres in LC233; and

- 2.63 g/t (0.077 oz/ton) over 3.0 metres in LC235.

(i)True widths of the mineralized intervals are interpreted to be
between 70-100% of the reported lengths. The Classified Mineral Resource
estimate comprises a cut-off grade of 0.30 g/t gold. Results less than 1
g/t not reported in this press-release table. "LCM" identifies

Approximately US$10 million of the US$14.1-million work-program budget
for 2009 will be spent on drilling, with 47,000 metres planned.
Approximately 5,900 metres and 56 holes have been drilled since April
2009. The balance of the year's budget will be spent on preliminary
environmental, engineering and metallurgical studies to begin assessing
potential processing options and economics of the deposit.

Fronteer owns more than 400,000 acres of mineral rights in this new
region. Long Canyon, Sandman and Northumberland are Fronteer's most
advanced gold projects and comprise the Company's future production
platform in Nevada.

Moira Smith, Ph.D., and Professional Geologist as recognized by the
Association of Professional Engineers and Geoscientists, British
Columbia, 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.
Drill samples were assayed by ALS Chemex (ISO9001:2000) in Reno, 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 and
continual monitoring 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.
