Clifton Star Resources Inc. ("CFO" or "Clifton") is pleased to announce the assay results for an additional 7 drill holes from its 2013 Duparquet Project drill program. Clifton Star continues to obtain good assay results from its ongoing drill program on the Duparquet Project.
The drill holes listed in this press release will not be included in the upcoming resource estimate update, as they were completed after the May 6th cut-off date.
Drill Highlights include:
- Hole BD13-22 with 34.0 meters grading 5.64 g/t Au (North Zone), including 11.7 metres grading 8.36 g/t Au and 7.5 metres grading 7.21 g/t Au.
- Hole D13-18 with 5.0 meters grading 5.58 g/t Au (South Zone), including 2.5 metres grading 9.45 g/t Au
- Hole CD13-12 with 6.0 meters grading 2.16 g/t Au (CD Zone)
Diamond Drilling Program
Clifton continues to delineate and increase the resources in the Duparquet Project by diamond drilling with 2 drill rigs. The drill results listed in this press release are from shallow (<100m vertical) holes that were drilled within or at the edge of the current pit shell in order to increase our confidence in the resource. (Click here for Figure 1). The attached table includes the most recent highlights from the 2013 drill program (Click here for Table 1). The true thicknesses of the intersections are typically 60% to 70% of the core lengths.
2013 Activities
Clifton has started a Pre-Feasibility Study on the Duparquet Project that will incorporate the results of the new resource estimate and the Pilot Plant tests.
Clifton 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 incorporated in the recently released PEA, as well as the potential to produce a High-Grade Gold Concentrates as an alternative process. The High-Grade Concentrate would only involve a flotation process, could be sold to Smelters, and would possibly result in lower Capex and Opex costs for the Duparquet Project. The permitting process would also be simplified. The results of the POX process and High-Grade Concentrate process are expected shortly from SGS Minerals, and will be incorporated into the Pre-Feasibility Study.
A new resource estimate is currently in the process of being prepared, and will include 97 drill holes completed during the 2012-13 Duparquet Project drill program as well as the results of the resampling of 19 holes from the Dumico property. This resource estimate is expected to be available at the end of June 2013.
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 analysis. 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'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.
