Fronteer Discovers New Gold-Silver-Copper Zone, Also Intersects 5.23 g/t Gold Over 25.5 Metres at the Agi Dagi Project, Turkey.

VANCOUVER, British Columbia -- Fronteer Development Group Inc ("Fronteer") (TSX:FRG)(AMEX:FRG) has discovered a new zone of gold-silver-copper mineralization at the Agi Dagi project ("Agi Dagi") in western Turkey. Drill hole AD-163, located 130 metres to the west of previous drilling in the Deli Zone, intersected 3.07 g/t gold, 13.8 g/t silver and 0.5% copper over 19.3 metres. This drill hole opens up the western flank of the Deli Zone for expansion to the north, west, and south, and demonstrates the untapped sulfide potential of the project, which until now had not been tested.

Hole AD-163 also returned two other distinct intervals of economically significant gold, silver and copper mineralization including:

- 2.37 g/t gold, 20.0 g/t silver, and 0.7% copper over 8.4 metres, and

- 3.77 g/t gold, 16.8 g/t silver, and 1.2% copper over 2.5 metres

For a complete description of the results from AD-163 please refer to the table at the end of this release.

In other important news, Fronteer has intersected additional gold-silver mineralization in drill hole AD-164, located 45 metres to the southwest of AD-126 which returned 3.75 g/t gold over 57.3 metres, and returned the following intersection:

- Hole AD-164 intersected 2.34 g/t gold over 66 metres including 5.23 g/t gold over 25.5 metres

This hole also returned 19.0 g/t silver over 48 metres coincident with the gold and bottomed in mineralization grading 0.8 g/t gold at a depth of 108 metres. Please see the table below for more details.

Other new assay results from ongoing metallurgical and infill drilling within the Deli Zone have also yielded notable gold grades. Specifically:

- Hole AD-154 intersected 1.25 g/t gold over 54.8 metres

- Hole AD-156 intersected 0.55 g/t gold over 47.8 metres

- Hole AD-157 intersected 0.84 g/t gold over 5.2 metres

- Hole AD-159 intersected 0.73 g/t gold over 16.5 metres

Exploration on Agi Dagi in 2005 has been very successful in both expanding the size of the Deli Zone and identifying emerging resource areas open for expansion. Geological models for the Baba and Deli resource areas at Agi Dagi are currently being constructed as a basis for 43-101 compliant resource estimates to be completed in January, 2006.

The Agi Dagi gold project is expected to be amenable to open-pit mining methods. The orientation of mineralized zones is sub-horizontal and stated widths are approximately 90% of true widths.

Agi Dagi is one of two advanced-stage gold properties currently being developed by Fronteer. The second property, Kirazli, is also being advanced to the resource definition stage, with a report scheduled to be completed for early 2006.

Fronteer also has a controlling 57% interest in an outstanding uranium district in Labrador, Canada. Results from a recently completed CAD $5.0 million, 9,400 metre drill program, are being released as they are received.

Finally, the Company will be drilling two new gold projects in Jalisco State, Mexico in early 2006, which have been recently optioned from Teck Cominco.
