Clifton Star Intersects 2.46 g/t Au Over 18.5 m and 2.50 g/t Au Over 17.0 m, at the Duparquet Project

QUEBEC CITY, QUEBEC--(Marketwired - Aug 21, 2013) - Clifton Star Resources Inc. ("the Company" or "Clifton Star") (TSX VENTURE:CFO)(FRANKFURT:C3T) is pleased to release the assay results for an additional 36 drill holes from its 2013 Duparquet Project drill program. Clifton Star continues to obtain positive assay results from its drill program.

The drill holes listed in this press release were not included in the recently published (June 28, 2013) NI 43-101 resource estimate update, as they were completed after the May 6^th cut-off date.

Drill Highlights include:

• Hole BD13-23 with 18.5 metres grading 2.46 g/t Au.
  
  
• Hole BD13-25 with 17.0 metres grading 2.50 g/t Au.
  
  
• Hole BD13-27 with 72.0 metres grading 1.14 g/t Au.
  
  
• Hole BD13-34 with 15.0 metres grading 2.27 g/t Au.
  
  
• Hole D13-20 with 21.9 metres grading 1.55 g/t Au.
  
  
• Hole D13-21 with 15.6 metres grading 2.22 g/t Au.
  
  
• Hole D13-27 with 43.5 metres grading 1.31 g/t Au.
  

Diamond Drilling Program

The results from 36 drill holes are listed in Table 1 (Click here to see Table 1). During this recent phase of drilling approximately 25% of the drill holes tested the mineralization within the current pit shells in order to upgrade the category of the resource, while the remaining 75% of the drill holes were drilled outside of the current pit shells in order to follow and extend interpreted mineralized zones (Click here to see Figure 1).

Drill holes BD13-25, D13-20 and D13-21 were drilled within the current resource and pit shells, upgrading the current resource. Drill holes BD13-23 (2.46 g/t Au / 18.5 m), BD13-27 (1.14 g/t Au / 72.0 m) and BD13-34 (2.27 g/t / 15m.) were all drilled within 5 to 25 metres from the edge of the current pit shell, potentially expanding the west pit shell. Hole D13-27 (1.31 g/t Au over 43 .5m) was drilled approximately 40 meters outside of the pit shell on the Donchester property, extending the mineralized envelope to the southeast. The true thicknesses of the intersections are typically 60% to 70% of the core lengths.

Clifton Star is pleased with these assay results, within and surrounding the pit shells, and that the mineralization remains open along strike and at depth. New drilling results are also expected to be available for publication in the coming weeks.

2013 Activities

Clifton Star has just completed drilling at Duparquet, having fulfilled its drilling objective of 20,000 meters for 2013.

The Company has completed its Pilot Plant tests with SGS Minerals in Lakefield, Ontario and is currently waiting for the final analysis and environmental work on the tailings. These metallurgical tests examined the POX (Pressure Oxidization) flow sheet as used in the recently released PEA, as well as the potential to produce saleable Gold Concentrates as an alternative process.

Clifton Star continues to advance the Pre-Feasibility Study on the Duparquet Project that will incorporate the results of the new resource estimate (June 28, 2013) and the Pilot Plant tests.

Technical Information and Qualified Persons

Diamond drill holes are drilled to recover NQ size core. The core samples are logged and sampled prior to being transported directly by the Company to Activation Laboratories Ltd. (Ste-Germaine de Boule), an independent accredited laboratory, for assay analyses. The assay analyses performed during Clifton's drill programs are subject to a formal quality assurance and quality control (QA/QC) program, with standard reference materials, blanks, and field duplicate samples inserted prior to shipment from site to monitor the quality control of the data. Samples with higher grade gold (greater than 10 grams per tonne) are re-assayed using a gravimetric and/or pulps and metallic procedure. All gold results reported are cut, with individual assays greater than 25 grams per tonne cut to 25 grams.

Clifton's exploration team designed and executed the 2013 drilling program under the supervision of Clifton Star's Vice President of Exploration, Mr. Louis Martin. The content of this news release has been written and approved by Mr. Louis Martin, P.Geo, a Qualified Person as defined by National Instrument 43-101.
