VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 06/13/11 -- Clifton Star Resources Inc. (TSX VENTURE: CFO)(FRANKFURT: C3T) has received an updated NI 43-101 compliant report from Peter Bevan, P.

The report, commissioned by Clifton Star, states a total of 22.512 million tonnes grading 1.84 g/t gold (1,332,000 ounces) in the measured and indicated category; and 4.650 million tonnes grading 2.02 g/t gold (302,000 ounces) in the inferred category, based on a cutoff grade of 0.50 g/t gold. Mr. Bevan utilized the polygonal method of calculation on a total of 218 drill holes.
