Allied Nevada Announces Development Studies at Hycroft and Provides Corporate Update

Begins Engineering Study on Crushing/Conveying System

RENO, NEVADA--(Marketwire - Sept. 10, 2009) - Allied Nevada Gold Corp. ("Allied Nevada" or the "Company") (TSX:ANV)(NYSE Amex:ANV) is pleased to announce development studies at its Hycroft gold mine located near Winnemucca, Nevada. The Company has completed an internal study aimed at optimizing production levels at Hycroft. The study considered the implementation of a crushing and conveying system and included an analysis of various potential mining rates.

The internal study considered crushing high silica content ore at Hycroft to improve gold recovery beyond the current expected average recovery of 56.6%. Historical gold recovery of crushed material from the Crofoot pit at Hycroft suggests that crushing ore may result in gold recoveries of approximately 75%, though further metallurgical testing is required to confirm those recoveries from our proven and probable reserves. This metallurgical testing will also establish expected silver recoveries for crushed ore. Current production of silver from our existing run of mine heap leach indicates that we are recovering approximately 10% of the contained silver.

A proposed crushing system would consist of a three-stage crushing and screening plant, overland conveyors and a stacking tower. This system would be capable of crushing six million tons per annum, to a final product size of 80% passing 1/2 inch minus. Based on crusher circuit capacity and mining rates, approximately 60% of the ore mined each month would be crushed. It is expected that, subject to additional metallurgical testing and final engineering, the purchase and installation of equipment would take place in 2010 for initial production in early 2011. If we are able to achieve an average recovery rate of 68% for both run of mine and crushed ore and a continued 30% increase in tons mined, we believe that gold production at Hycroft could be increased by up to 45% in the first five years following full implementation of the crushing and conveying system.

Estimates for operating and capital costs as well as throughput and metals recovery rates are based on historic recovery and cost data and independent operating cost data in the region. The internal study used a capital cost estimate of approximately $25 million, an operating cost of $1.25 per ton of ore crushed, and an expected gold recovery of approximately 75%. The study indicated that if we were to selectively crush the higher grade ore, we would expect gold grades to be approximately 25% higher than the average gold grade of the deposit of 0.55 grams per tonne. The study used an assumed silver recovery of 10%.

In addition, the Company has been using a contract miner to increase the mining rate by approximately 30% at Hycroft for the past few months. While this has been a successful program, the Company believes that it may be able to add additional mining equipment and its own employees to increase production in a more cost-effective manner. The internal study did not identify an optimal mining rate, but did indicate that additional optimization and engineering work is required.

"We are excited with the future potential at Hycroft. These development opportunities are relatively simple, logical next steps for the current run-of-mine heap leach operation. The mine is running smoothly and our focus is to ensure it maintains this, however, we are committed to optimizing the operation in order to realize the full potential of the mine to benefit all stakeholders," remarked Scott Caldwell, President & CEO.

As of June 30, 2009, Allied Nevada had a cash and cash equivalent balance of $12.8 million. With the completion of the C$100.4 million (approximately US$91.5 million) cross-border public offering, the Company has at August 31, 2009, a cash balance of more than US$100 million.

The Company has initiated the environmental permitting necessary to address the development of the gold and silver resource at Hycroft. A plan of operations is expected to be submitted to the Bureau of Land Management in the fourth quarter of 2009.
