QUEBEC CITY, QUEBEC--(Marketwired - June 28, 2013) - Clifton Star Resources Inc. ("Clifton Star" or "the Company") (TSX VENTURE:CFO)(FRANKFURT:C3T) is pleased to announce a substantial increase in the gold resource at its Duparquet Project. The updated estimate of the Measured + Indicated Resource contains 3.11 million ounces with another 1.44 million ounces in the Inferred category. The NI 43-101 resource estimate, dated June 26, 2013, will be filed on SEDAR in the coming weeks.
Resource Highlights include:
The new NI 43-101 resources estimate was prepared by InnovExplo Inc., mining consultants from Val d'Or, Quebec and will be incorporated in the upcoming Pre-Feasibility study on the Duparquet gold project. The block model was prepared by using 3D block modeling and inverse distance squared interpolation method. The updated resource database currently consists of a total of 849 diamond drill holes, accounting for 260,948 meters, with 168,555 sample intervals. It also includes 2,371 samples from 892 surface channel samples, equivalent to 1,827 sampled meters. This database includes all the drilling and assay results up to the cut-off date of May 6th, 2013. A high grade capping of 25g/t Au and a minimum true thickness of 3 meters were used. Mining and milling costs of $2.40USD/t and $13.46USD/t and G&A of $4.18/t USD were used in the Whittle open pit simulations. For the base case scenario, a $1445 USD /oz. gold price and a cut-off grade of 0.45 g/t Au were used for determining the in-pit resources. For the underground resources, a cut-off grade of 2.00 g/t was used for the base case. These parameters are the same as those used in the February 28, 2013 NI 43-101 resource estimation.
The purpose of the drilling since the last resource estimate was to convert existing Inferred Resources to Indicated Resources and to better define the continuity and quality of the open pit resources between surface and a depth of 350 meters. On the basis of contained ounces, more than 68% of total resources (3.11 million ounces) are now in the Measured + Indicated categories. Of these Measured and Indicated Resources, 2.67 million ounces are located within the Whittle pit shell. This new In-Pit resource of Measured + Indicated Resources is composed of 53,235,700 tonnes at an average grade of 1.56 g/t Au.
The Total Mineral Resource estimate is as follows:
- Measured resources: | 9,006 ounces | (184,700 t at 1.52 g/t) |
- Indicated resources: | 3,104,165 ounces | (60,696,300 t at 1.59 g/t) |
- Inferred resources: | 1,442,689 ounces | (29,684,700 t at 1.51 g/t) |
The In-Pit Mineral Resource, base case, is as follows (official cut-off 0.45 g/t):
- Measured resources: | 7,711 ounces | (165,100 t at 1.45 g/t) |
- Indicated resources: | 2,666,690 ounces | (53,070,600 t at 1.56 g/t) |
- Inferred resources: | 910,631 ounces | (24,092,300 t at 1.18 g/t) |
The Underground Mineral Resource, base case, is as follows (official cut-off 2.0 g/t):
- Indicated resources: | 314,275 ounces | (3,520,700 t at 2.78 g/t) |
- Inferred resources: | 532,059 ounces | (5,592,400 t at 2.96 g/t) |
The Beattie Tailings Resource, base case is as follows (official cut-off 0.45 g/t):
- Measured resources: | 1,295 ounces | (19,600 t at 2.06 g/t) |
- Indicated resources: | 123,200 ounces | (4,105,000 t at 0.93 g/t) |
The mineral resources stated in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) standards on mineral resources and reserves, definitions, and guidelines prepared by the CIM standing committee on reserve definitions and adopted by the CIM council.
Technical parameters used for the estimation:
