Fronteer Development Group Inc.: Halilaga Project Returns One of the Highest Grade Copper-Gold Intercepts To Date

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 11, 2007) - Fronteer Development Group Inc. ("Fronteer") (TSX:FRG)(AMEX:FRG) announced today that a new drill hole at its Halilaga porphyry project in northwestern Turkey has returned one of the highest grade intervals of copper-gold mineralization to date, intersecting an important secondary copper enrichment zone.

Drill hole HD-14 intersected a thick zone of mineralization starting at surface that returned 0.47% copper and 0.42 grams per tonne gold over 278.20 metres, including:

- 0.58% copper and 0.51 grams per tonne gold over 211.25 metres starting at surface.

- A gold-rich zone starting at surface that returned 1.49 grams per tonne gold over 14.3 metres.

- A zone of secondary copper enrichment that returned 2.42% copper and 0.96 grams per tonne gold over 24.8 metres starting at a depth of 14.3 metres.

HD-14 was a 50-metre step-out hole drilled between HD-01 and HD-02, which recently returned 0.53% copper and 0.50 grams per tonne gold over 298.2 metres, and 0.35% copper and 0.40 grams per tonne gold over 292.8 metres, respectively.

"Halilaga has many of the hallmarks of a world-class porphyry deposit in terms of size, grade and continuity," says Mark O'Dea, Fronteer President and CEO. "Copper enrichment zones, like the one we see at Halilaga, are important economic components of successful copper-gold mines."

This new porphyry deposit is now defined by 11 widely spaced drill holes, all of which have intersected broad zones of copper-gold mineralization. These holes have tested an area measuring at least 1,000 metres in length and up to 400 metres in width, with mineralized intervals, on average, of greater than 200 metres in thickness.

Halilaga is located along the same mineral belt as Agi Dagi and Kirazli, two anchor assets in Fronteer's gold portfolio in northwestern Turkey. Together, these projects form an emerging gold and copper district that Fronteer is playing a leadership role in building.

Detailed results for HD-14 and the entire project are as follows:
