Clifton Star Announces Start of the Duparquet Gold Project PEA and Appoints Dr. David Dreisinger as Vice President Metallurgy

QUEBEC CITY, QUEBEC -- (Marketwire) -- 08/20/12 -- Clifton Star Resources Inc. ("Clifton Star" or "The Corporation") (TSX VENTURE: CFO)(FRANKFURT: C3T) is pleased to report that it has started the preparation of a Preliminary Economic Assessment report ("PEA") on the Duparquet Project.

Three engineering firms will be involved in completing the PEA.

InnovExplo, a Mining Consulting Firm from Val-d'Or, ("InnovExplo") will update the resource estimation, incorporating the latest 2012 drill and surface sampling results, and will design the mining sequence for the open pit operations. InnovExplo will also be responsible for the integration of all other aspects of the report as the lead author.

Bateman Australia Pty Ltd ("Bateman") will design the metallurgical treatment circuit and mill, including the pressure oxidation circuit, based on the metallurgical tests carried out by SGS-Lakefield over the past months that resulted in an average of 93% gold recovery. Bateman will also provide a comparative study on the capex/opex of the alternative BIOX™ and Albion processes, which have delivered similar gold recoveries in recent tests.

Stavibel Engineering Services, ("Stavibel"), a subsidiary of SNC-Lavalin, will study all the environmental and social aspects of the project. Since gold mining and ore processing were carried in the past on the project, Stavibel will initially characterize the site. Stavibel will also evaluate and design waste rock and tailings storage facilities, water control and balance for the open pit mining and milling scenarios as designed by InnovExplo and Bateman.

Clifton Star expects to have the PEA report completed at the end of 2012 and to publish the conclusions in January of 2013.
