Allied Nevada Drills 36 Meters Grading 3.13 g/t Gold Equivalent in the North Brimstone Area at the Hycroft Mine

RENO, NEVADA -- (Marketwire) -- 09/09/10 -- Allied Nevada Gold Corp. ('Allied Nevada' or the 'Company') (TSX: ANV)(NYSE Amex: ANV) is pleased to provide an update on recent North Brimstone drilling at its wholly owned Hycroft mine, located west of Winnemucca, Nevada. Highlights from this drilling include 36 meters grading 3.13 g/t AuEq (2.52 g/t Au and 35 g/t Ag) and 50 meters grading 1.01 g/t AuEq (0.57 g/t Au and 25 g/t Ag). The intercepts encountered in these recently drilled holes are higher than the average proven and probable reserve grades of 0.48 g/t Au and 7.54 g/t Ag.

The following table includes significant intercepts encountered in the North Brimstone drilling. Assays indicate that the material is potentially oxide leachable material.

'Drilling in the North Brimstone area has been encouraging, with the grades encountered in these intercepts being higher than the average gold and silver grades of our proven and probable reserves,' commented Dave Flint, Vice President, Exploration for Allied Nevada. 'Based on these encouraging results, we are planning to drill six additional holes in the North Brimstone area, with a goal of expanding the resource in this area by year-end.'

This area of drilling is located north of the producing Brimstone Mine, and is not included within the current proven and probable reserve pit. The North Brimstone material is contiguous with the Brimstone deposit to the south. At present this zone is approximately 250 by 185 meters, and extends to a depth of 240 meters.

Year-to-date, 263 infill and exploration holes totaling 63,468 meters have been drilled at Hycroft. The exploration program for the second half of 2010 consists of an additional 160 holes. Allied Nevada continues to explore with a drill fleet of eight rigs, with a focus on infill and expansion of the oxide and sulfide mineralization, as well as providing material for engineering, slope stability analysis and ongoing metallurgical testing.

Allied Nevada maintains a strict quality control program at all of its projects. Drill samples are gathered on-site and validated by Allied Nevada and Scott E. Wilson Consulting, Inc. geologists to be shipped to ALS Chemex's assaying laboratories in Reno, Nevada. Gold and silver analyses are conducted on 1-assay ton prepped samples with gold and silver determined using industry standard fire assay methods with an atomic absorption finish. Gold and silver over limits are determined using fire assay with a gravimetric finish.
