Fronteer Development Group Inc.: Porphyry Copper-Gold Mineralization Expands Significantly at Halilaga, NW Turkey

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 25, 2007) - Fronteer Development Group Inc. ("Fronteer") (TSX:FRG)(AMEX:FRG) is pleased to report that encouraging porphyry copper-gold mineralization at Halilaga has been extended by an additional 800 metres along strike. Mineralization has now been intersected over a one kilometre strike length in eight widely-spaced drill holes, demonstrating the potential for this property to host an economically significant copper-gold deposit.

Drill hole HD-08, drilled 800 metres east of previously released holes, has intersected:

- 0.91 grams per tonne gold and 0.41% copper over 43.9 metres as part of a broader interval that returned 0.50 grams per tonne gold and 0.26% copper over 267.3 metres.

Drill hole HD-07A, drilled 400 metres east of the previously released holes, has intersected:

- 0.30 grams per tonne gold and 0.22% copper over 241.2 metres; including 0.52 grams per tonne gold and 0.35% copper over 10.0 metres.

"We continue to be encouraged by the size and continuity of this new porphyry system," says Dr. Mark O'Dea, Fronteer President and CEO. "All eight holes that intersected this new system have returned significant copper-gold grades over an average thickness of 250 metres."

(1) Copper and gold-equivalent calculations use metal prices of US$689/oz
for gold and US$3.65/lb for copper. Metallurgical testing has yet to
be conducted for the Halilaga project. Therefore, copper and
gold-equivalent calculations reflect gross metal content that has not
been adjusted for metallurgical recoveries.

The true width of mineralized zones is estimated to be 90 per cent of those stated.

Currently, there is one drill rig turning at Halilaga. The 2007 exploration program is focused primarily on the broader geophysical footprint of the Central Zone, as well as drilling into the wide zone of known surface mineralization. Teck Cominco Limited's Turkish subsidiary ("TCAM") has the property under option from Fronteer and is currently the operator. TCAM has exercised its right to earn back a 60% interest in the Halilaga project, which is 100%-owned by Fronteer.
