VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 17, 2009) - Clifton Star Resources Inc. (TSX VENTURE:CFO)(FRANKFURT:C3T) is pleased to announce that the recent assays obtained from the extended core sampling program at the Beattie gold deposit demonstrate the presence of broad zones hosting lower-grade gold that may be amenable to large-scale, open-pit mining methods. Highlights include:Table 1. Highlights of Extended Core Sampling Program for Beattie Deposit. ------------------------------------------------------------------------- Drill After-New Intervals Before-Corresponding Old Intervals Hole (0.4 g/t Au cut off) (2.0 g/t Au cut off, minimum width 2.0 m) ------------------------------------------------------------------------- B08-84 173.5 m at 0.98 g/t Au 7.0 m at 4.09 g/t Au & 14.0 m at 4.02 g/t Au ------------------------------------------------------------------------- B08-83 100.3 m at 1.17 g/t Au 10.0 m at 2.71 g/t Au & 8.0 m at 4.95 g/t Au ------------------------------------------------------------------------- B08-47 15.5 m at 1.00 g/t Au No historical interval ------------------------------------------------------------------------- B08-27 43.85 m at 0.51 g/t Au No historical interval ------------------------------------------------------------------------- B08-27 37.80 m at 1.30 g/t Au 10.9 m at 2.24 g/t Au ------------------------------------------------------------------------- B08-07 40.33 m at 0.81 g/t Au 2.83 m at 3.94 g/t Au ------------------------------------------------------------------------- B93-03 53.02 m at 1.10 g/t Au 2.73 m at 3.00 g/t Au; 4.10 m at 2.44 g/t Au; 2.42 at 2.46 g/t Au ------------------------------------------------------------------------- Mr. Harry Miller, President of Clifton Star Resources, commented as follows: "We are pleased that this first batch of assays from the old core continues to confirm our belief that broad and extensive zone of approximately 1 g/t gold may occur at our Beattie, Donchester, Central Duparquet, and Dumico gold deposits. It is remarkable that the new intervals are typically four-to-five times wider than the higher-grade gold zones previously reported. At a minimum, these broader gold zones should add substantial tonnage and ounces to the project. If spatial continuity can be demonstrated for these new and wider zones, then these zones may be amenable to low-cost, open-pit mining similar to the Canadian Malartic deposit located nearby. More samples from the old core are currently being prepared and shipped to the assay lab. We will continue to report the results from this program as assays arrive in the weeks ahead." Rationale for the Extended Core Sampling Program Historical mining at the Beattie, Donchester, Central Duparquet, Duquesne, and Dumico deposits yielded large quantities of gold from high-grade veins using traditional underground mining methods. At least four major vein systems or zones are present: the North, South, RW, and RS. In the past, geologists submitted for assay only those portions of the drill holes cutting these four major zones, leaving the remainder of the drill core un-split and un-sampled. It is estimated that more than 80% of all core drilled at the Beattie-Donchester-Central Duparquet-Dumico went un-sampled. In the past few years it has been demonstrated at a few gold projects in eastern Canada that significant tonnages of lower-grade material may occur near-or-about the known narrow veins that were mined in the past. The premier example is the Canadian Malartic project, owned and operated by Osisko Mining. Recently Clifton Star geologists and independent mining analysts have recognized that the Beattie-Donchester-Central Duparquet-Dumico and the Canadian Malartic deposits share key geological similarities, leading to the tentative conclusion that the Beattie-Donchester-Central Duparquet-Dumico may also host important lower-grade gold zones surrounding the higher-grade veins structures. Review of the historical assay data pertaining to the Beattie-Donchester-Central Duparquet-Dumico deposits has confirmed this possibility. In June of this year Clifton Star began an extensive program to assay the previously un-sampled core drilled since 1987 as a means to evaluate further the possibility for substantial zones of lower-grade gold similar to those found at Canadian Malartic. Current Progress of the Extended Core Sampling Program Clifton Star is working with the engineering firm of Scott-Wilson-Roscoe-Postle Associates Inc. and Peter Bevan, P Eng., regarding the selection of the specific cores for extended sampling. Samples are now being submitted to analytical labs on a daily basis. It is estimated that the present extended sampling program will require another six weeks to complete. Clifton Star will be commissioning an updated NI 43-101 resource estimate for the Beattie-Donchester-Central Duparquet-Dumico-Duquesne deposits upon completion of the extended core sampling program. It is anticipated that this updated report will provide the first look at a shallow resource that may be amenable to large-scale, open-pit mining methods. Table 2.

Estimate Clifton Star announced on Sept 8, 2009, an updated NI 43-101 resource estimate by Peter Bevan, P Eng., for the Beattie and Donchester deposits (see Table 3). These resources were calculated without the benefit of the results of the extended core sampling program described above. As a result, the resources shown below in Table 3 consist mostly of mineralized rock confined to the North, South, and RW vein structures. Table 3.
