Allied Nevada Completes Successful First Quarter 2012 Hycroft Drill Program Highlighted by 116 Meters of 0.75 g/t Gold and 45.6 g/t Silver (1.6 g/t Gold Equivalent(1))08:30 EDT Wednesday, April 04, 2012RENO, NEVADA--(Marketwire - April 4, 2012) - Allied Nevada Gold Corp. ("Allied Nevada" or the "Company") (TSX:ANV)(NYSE Amex:ANV) is pleased to provide an update for the first quarter 2012 drill program at its wholly owned Hycroft mine located near Winnemucca, Nevada. Highlights for drilling in the first quarter of 2012 include 116 meters grading 0.75 g/t Au(1) and 45.6 g/t Ag(2) (1.6 g/t AuEq(1),(2)) and 56 meters grading 0.98 g/t Au and 59.7 g/t Ag (2.0 g/t AuEq) of mill material. Heap leach material drilling highlights include 11 meters grading 1.84 g/t Au and 122.4 g/t Ag (4.0 g/t AuEq). The primary goals for the drill program in the first quarter of 2012 were collecting material for engineering support of the expansion projects and ongoing metallurgical optimization work. These results also provided additional data to infill areas within the next resource model. "We successfully completed the planned first quarter drill program for 2012 and are pleased with the results," commented Dave Flint, Vice President of Exploration. "Drilling continues to intersect average to better than average grade material within the deposit." The material gathered in 2012 is primarily being utilized for ongoing metallurgical optimization and engineering work in association with the expansion projects. Core samples are being utilized to create large quantities of concentrate for optimization work and to provide samples for testing in offsite processing facilities. The Company continues to review additional process methods for the concentrate, such as fine grind and leaching.For a full list of the assay results for the 2012 drill program and a current drill map showing the locations of current and planned holes, please go to our website at 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 and Inspectorate assay 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.GRADE (g/t)Hole IDFROMmetersTOmetersINTERVALmetersAuAgAuEqLOCATIONNature of Mineralization4074212255430.6528.31.1VortexTransitional + Sulfide4214370427570.9859.72.0BrimstoneTransitional + Sulfide42293164311150.7545.61.6VortexTransitional + Sulfide429698109111.84122.44.0BrimstoneOxide4301154188340.7216.21.0VortexSulfideand346442960.4831.21.0VortexSulfideand472489171.6410.21.8VortexSulfide43032253310.51118.52.6BrimstoneOxideCautionary Statement Regarding Forward Looking InformationThis press release contains forward-looking statements within the meaning of the U.S. Securities Act of 1933 and the U.S. Securities Exchange Act of 1934 (and the equivalent under Canadian securities laws), that are intended to be covered by the safe harbor created by such sections.
