Expansion Of Main Mineralized Zones At Hasbrouck  

RENO, NV - Allied Nevada Gold Corp. reported highlights from the final drilling of the 2011 season at its wholly owned Hasbrouck project, located five miles south of Tonopah, Nevada. Recent assays indicate extension of mineralization on the east side of the hill and continuity between the Franco and Crossroads zones.

Drilling has confirmed and extended the Franco Zone mineralization, and connected the Crossroads Zone to the Franco Zone. Additionally, mineralization was encountered on the south and east sides of the hill in previously sparsely drilled areas.

Hole 99 was drilled from the Franco Zone to the west towards the Crossroads Zone to fill in the untested area between. This hole encountered additional higher grade material including a 3-meter interval of 8.3 g/t gold and 30.8 g/t silver. Holes 107 and 115 were designed to fan out from the core hole 99 success, and to step out and extend Franco mineralization. These holes successfully encountered additional higher grade material including 171 meters grading 1.1 g/t gold and 33.5 g/t silver.

Project to date, Allied Nevada has drilled 26,095 meters in 116 holes at Hasbrouck. The drill program has been primarily directed towards resource expansion and further definition of the high grade potential. The Company will use the data obtained in the 2011 drill season to complete an updated resource model, which will form the basis for the preliminary economic assessment, due to be completed in the first quarter of 2012.

Hasbrouck mineralization was deposited by an epithermal hot-spring system and is accompanied by pervasive silicification and oxidization, with associated adularia and pyrite. The high-grade mineralization is hosted in intensely silicified, veined, and hydrothermally brecciated sedimentary and tuffaceous volcanic rocks. The property is located approximately 50 miles south of the Round Mountain open pit mine.

Allied Nevada maintains a strict quality control program at all of its projects. Drill samples are picked up on site and validated by Allied Nevada geologists to be shipped to ALS Chemex's assaying laboratories in Reno, Nevada. Gold analysis is conducted on 1-assay ton prepped samples with gold determined using industry standard atomic absorption and fire assay methods. Primary silver analysis is by the 1-assay ton gravimetric method.
