Fronteer Development Group Inc.: Metallurgical Tests Confirm Excellent Gold Recoveries at Agi Dagi and Kirazli Gold Deposits

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - June 6, 2006) - Fronteer Development Group Inc. ("Fronteer") (TSX:FRG)(AMEX:FRG) ("the company") announced today that new metallurgical tests on its 100% owned Agi Dagi and Kirazli gold projects have yielded gold recoveries averaging 92% within an average of 17 days of leaching. These excellent results confirm that both deposits are amenable to low cost heap leach processing.

Sixteen heap leach column tests were conducted by Kappes Cassiday and Associates on six samples from the Agi Dagi deposit and two samples from the Kirazli deposit. Two column tests were conducted on each sample; the first at a coarse crush size (approximately 20 millimeters), and the second at a fine crush size (approximately 6 millimeters).

The Agi Dagi test work was conducted on fresh oxide material from five diamond drill holes (ten samples) and a surface trench (two samples). The samples ranged in grade from 0.47 grams per tonne gold to 4.52 grams per tonne gold (see Table 1 for details). Recoveries averaged 90% for the coarse crushed material and 91% for the fine crushed material. The average leach time to reach the maximum extractions was 17 days.

The Kirazli test work was conducted on fresh oxide material from one diamond drill hole (four samples) using material from a high-grade section (7.68 and 7.36 grams per tonne gold) and material from a low-grade section (0.54 grams per tonne gold) (See Table 1). The recoveries from the coarse crushed samples averaged 94% and the samples from the fine crushed samples averaged 95%. Maximum extractions were reached in 13 days.

"We are encouraged by these metallurgical results. They confirm that a relatively standard crushing circuit should be possible at both projects and that processing costs should not be excessive," says Mr. Jim Lincoln, VP Operations of Fronteer.

Teck Cominco Limited's Turkish subsidiary (Teck Cominco Arama ve Madencilik y Sanayii A.S.) ("TCAM") has recently elected to exercise its right to earn a 60% interest in both the Agi Dagi and Kirazli projects, currently owned 100% by Fronteer. Before April 30th, 2007, TCAM is required to spend US$5 million at Agi Dagi and US$2.5 million at Kirazli. These expenditures will significantly advance both projects towards development and are anticipated to increase the size of both deposits.

Mr. Jim Lincoln, V.P. Operations of Fronteer Development Group Inc., is the designated Qualified Person for Fronteer.


Over the past year, Fronteer has demonstrated its ability to make new discoveries. The company has rapidly advanced both the Agi Dagi and Kirazli gold projects towards feasibility and made a new silver-gold discovery in Mexico. In uranium, Fronteer has established the Michelin deposit to be one of the largest undeveloped uranium deposits in Canada outside of Saskatchewan.

Fronteer has US $51 million in the treasury and will continue to seek new projects and acquisitions.
