Fronteer Development Group Inc.: Long Canyon Column-Leach Tests Return Gold Recoveries Averaging up to 90.1% Thursday June 11, 7:00 am ET ca.us.biz.yahoo.com VANCOUVER, BRITISH COLUMBIA--(MARKET WIRE)--Jun 11, 2009 -- Fronteer Development Group Inc. (Toronto:FRG.TO - News)(AMEX:FRG - News) is pleased to announce that column-leach testing of bulk samples from the Long Canyon project have returned gold recoveries averaging as high as 90.1%. The metallurgical test data suggests Long Canyon's oxidized gold mineralization is amenable to low-cost, conventional, heap-leach processing. Four bulk samples were submitted to McClelland Laboratories Inc. in Sparks, Nevada, for column-leach tests at crush sizes of -25 mm and -75 mm. Column-leach gold recoveries for the -75mm feed size ranged from 84.2% to 96.6% (89.7% average) in approximately 65 days of leaching and rinsing. Column-leach gold recoveries for the -25mm feed size ranged from 85.6% to 96.3% (90.1% average) in approximately 69 days of leaching and rinsing. Gold recovery rates for all samples were very rapid and gold extraction was substantially complete in 10 to 15 days of leaching. Reagent consumption levels were also very low and no solution percolation, fines migration, solution channeling or slumping problems were encountered during column leaching. For charts showing cumulative gold recoveries among all four samples, please click: fronteergroup.com. The four bulk metallurgical samples, each weighing approximately 1.5 tonnes, were obtained from separate road cuts on the Long Canyon property. The sample sites all presented a mix of competent rock and soil-like fines and efforts were taken to get proportional amounts of the fines and coarse rock. Three of the samples were Notch Peak limestone, while the fourth was Pogonip limestone. Further metallurgical testing will be completed as part of Long Canyon's current $14.1 million work program. Tests will be conducted over the course of this year's program on composite material obtained from 17 large-diameter core holes that were drilled in May on three mineralized cross sections. Fronteer is majority owner (51%) and operator of Long Canyon through a joint venture with AuEx Ventures Inc. (49%). Long Canyon recently reported its first resource estimate (See March 13, 2009 press release). The Long Canyon resource defined to date is essentially all oxide and characterized by wide intervals of at- or near-surface, high-grade, gold mineralization and remains open in all directions, including at depth. Long Canyon, Sandman and Northumberland are Fronteer's most advanced gold properties and comprise the Company's future production platform in Nevada.
