Allied Nevada Drills 125 Meters of 0.7 g/t Gold and 158.0 g/t Silver (4.3 g/t Gold

Equivalent¹) in the Vortex Zone at Hycroft

July 6, 2011 | Reno, Nevada - Allied Nevada Gold Corp. (“Allied Nevada” or the “Company”) (TSX: ANV; NYSE-Amex: ANV) is pleased to announce recent drill results from the ongoing exploration program at its wholly owned Hycroft mine located near Winnemucca, Nevada. The results of infill drilling in the Vortex Zone continue to intercept intervals of mineralization at or above the average grade of the resource. Highlights from recent Vortex drilling include 125 meters grading 0.7 g/t Au² and 158.0 g/t Ag² (4.3 g/t AuEq²) and 22 meters grading 2.6 g/t Au and 219.8 g/t Ag (7.6 g/t AuEq). Drilling at Hycroft will continue through year end with five to six drill rigs.

“The infill drill program in the Vortex Zone continues to be successful with results indicating higher than average grades,” commented Dave Flint, Vice President of Exploration. “We have completed initial exploration tests on targets outside the current resource that indicate potential for resource expansion. Hycroft mineralization remains open to the north, south, west and at depth.”

Allied Nevada maintains a strict quality control program at all of its projects. Drill samples are gathered on-site and validated by Allied Nevada 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 determined using industry standard fire assay methods with an atomic absorption finish. Gold over limits and silver are determined using fire assay with a gravimetric finish.
