Allied Nevada Provides Update on Mining Equipment Deliveries

April 23, 2012 | Reno, Nevada - Allied Nevada Gold Corp. (“Allied Nevada” or the “Company”) (TSX: ANV; NYSE-Amex: ANV) has recently learned that the final Hitachi EX5500 shovel shipped from Japan on April 22, 2012. The shipping is about a month behind schedule due to logistical issues at the port stemming from damage sustained during the March 2011 tsunami. The 2012 mine plan assumed the shovel would be in operation in the beginning of June, 2012. Based on logistics discussions with the manufacturer, the Company believes that the shovel will now be in operation in the third quarter.

As a result of this delayed delivery, it is anticipated that the mid to lower end of previously stated production guidance range of 180,000 to 220,000 ounces of gold will be achieved in 2012, assuming all other equipment deliveries are on time through the remainder of the year. In addition, mining unit costs may be slightly higher for a few months as the Company utilizes higher cost loading units and with the utilization of a contractor to haul crushed ore to the leach pads to free up Hycroft equipment to focus on mining operations. Unit costs are expected to decline as the new equipment becomes operational. A contractor is being used to haul crushed ore to the leach pads to free up Hycroft equipment to focus on mining operations.

The Company recently took delivery of the first two of nine of the new 930E haul trucks slated to be delivered in 2012, which arrived slightly ahead of schedule. Permits to begin construction of the crushing plant have been received ahead of schedule. A contract miner is being utilized to complete excavation and ground work preparation for the crushing plant, which was included in the capital cost estimate.

“We are encouraged with the prompt delivery of the haul trucks, however the further delay of the shovel delivery is disappointing,” commented Scott Caldwell, President and CEO of Allied Nevada. “We will continue to monitor the situation and employ mitigation strategies such as utilizing contract mining equipment to progress the heap leach expansion.”
