Clifton Star Announces Final 2012 Drilling Results from the Duparquet Project Including 3.21 g/t Au Over 24.8m and 2.15 g/t Au Over 39.0m
QUEBEC CITY, QUEBEC -- (Marketwire) -- 02/14/13 -- Clifton Star Resources Inc. ("CFO" or "Clifton") (TSX VENTURE: CFO)(FRANKFURT: C3T) is pleased to announce the assay results from the remaining 23 drill holes from its 2012 drill program at the Duparquet Project of Quebec's Abitibi region.
All of the drill holes listed in this press release were completed after the PEA study closing date, and therefore were not included in the new resource estimate of the recently published (January 15, 2013) PEA which showed a pre-tax NPV of $382M (5% discount rate) and a 19.5% IRR for the Duparquet project at a gold price of US$1472 per ounce. At a gold price of US$1700 per ounce, the PEA showed a pre-tax NPV (5% discount rate) of $621 million, an IRR of 27.6%, and a payback period of 2.95 years.
Clifton Star continues to obtain significant assay results from both delineation holes within the limits of the current pits shells and exploration holes outside of the pits shells. The positive results within the pits limits demonstrate that the zones show good grades and continuity, while the exploration holes demonstrate the potential to increase the limits of the current pits shells. (Click here for Figure 1http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-1.jpg)
Drill Highlights include:
-- Hole BD12-29 with 28.5 meters grading 2.15 g/t Au (Syenite Zone)
-- And BD12-29 with 33.0 meters grading 1.61 g/t Au (RS/RW Zone)
-- Hole D12-36 with 7.5 meters grading 3.03 g/t Au (Syenite Zone)
-- And Hole D12-36 with 24.8 meters grading 3.21 g/t Au (North Zone)
-- Hole CD12-11 with 4.0 meters grading 8.86 g/t Au (CD Zone)
-- Hole CD12-12 with 6.0 meters grading 4.89 g/t Au (CD Zone)
-- Hole CD12-13 with 39.0 meters grading 2.15 g/t Au (CD Zone)
-- Hole CD12-15 with 22.0 meters grading 1.88 g/t Au (CD Zone)
-- Hole BD12-23 with 22.0 meters grading 1.69 g/t Au (RS/RW Zone)
-- Hole BD12-27 with 39.3 meters grading 1.17 g/t Au (Syenite Zone)
The results of these 23 drill holes, as well as a majority of the drill results reported in the press release by Clifton Star on October 16th, 2012 (17 out of the 19 holes released) and all those shown in the December 3rd Press Release (14 holes), for a total of 54 holes (16,150.5 meters), were not included in the most recent NI 43-101 Resource estimate published January 15, 2013, on which the Preliminary Economic Assessment (PEA) was based.
Overview of 2012 Drilling Program
Clifton Star has completed its 2012 drill program on the Duparquet Project by drilling throughout the year at a steady pace with 2 drill rigs. The 2012 drill program on the Duparquet project included the completion of 98 holes totalling 33,480 m.
Drill Results
The 2012 assay results continue to be very encouraging for both the exploration holes outside of the pit shells and the definition holes within the current proposed pit shell. The true thicknesses of the intersections are typically 60% to 80% of the core lengths.
Following are some of the highlights from the assay results of the last 23 holes of the 2012 drill program, with the results of all 23 holes shown in Table 1:
Hole BD12-23 intersected 1.69 g/t Au over 22.0 m outside of the current pit shell at approximately 140 m below the surface. This intersection is part of the larger RS/RW zone that is well developed to the west (Click here for Figure 2http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-2.jpg).
Hole BD12-27 intersected 1.17 g/t Au over 39.3 m along the edge of the pitwall at approximately 75m below the surface. This included several higher grade sections of 2.61 g/t over 4.3 m, 4.01 g/t Au over 3.1 m and 2.90 g/t Au over 3.5 m. This mineralization is hosted within the larger Syenite envelope between the RS/RW Zone and the South Zone (Click here for Figure 3http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-3.jpg).
Hole BD12-29 intersected multiple sections of widespread gold mineralization. The first section assayed 2.15 g/t Au over 28.5 m, including a higher grade section of 3.73 g/t au over 11.9 m, within Zone 6. The second wider interval returned an assay of 1.61 g/t Au over 33.0 m, including higher grade intervals of 4.33 g/t Au over 3.0 m and 4.37 g/t Au over 5.0 m from within the RS/RW Zone (Click here for Figure 4http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-4.jpg).
Hole D12-36 intersected several mineralized intersections along the western wall of the pit shell. The best intersections included 3.03 g/t Au over 7.5 m within the Syenite Zone, just outside of the Pitwall at a vertical depth of 70 m below the surface, and 3.21 g/t Au over 24.8 m at the bottom eastern extension of the Donchester pit at a depth of 170 m below the surface (Click here for Figure 5http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-5.jpg).
Drilling of the Inferred Resources material within and surrounding the Central Duparquet pit shell demonstrated the continuity of these resources. Hole CD12-11, located near the bottom of the current pit shell at approximately 100 m below the surface, returned a high-grade section of 8.86 g/t Au over 4.0 m (Click here for Figure 6http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-6.jpg).
Hole CD12-12, located 100m to the east of hole CD12-11, intersected a zone of 4.89 g/t Au over 6.0 m at a depth of 100 m below the surface. Hole CD12-13, located 50 m up dip from CD12-12, intersected widespread mineralization with 2.15 g/t Au over 39.0 m (Click here for Figure 7http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-7.jpg ).
A further 100 m to the east, hole CD12-15 intersected widespread mineralization, with 1.88 g/t Au over 22.0 m at less than 100 m below the surface (Click here for Figure 8http://www.cfo-star.com/wp/wp-content/uploads/2013/02/PR_Feb2013_v1-Image-8.jpg).
2013 Activities:
On January 15th, Clifton Star reported the results of its positive PEA. The financial analysis, using a gold price of US$1,472 per ounce, indicated a pre-tax net present value ("NPV") (using a 5 % discount rate) of $382 Million, with a pre-tax internal rate of return ("IRR") of 19.5%. At a gold price of US$1700 per ounce, the PEA showed a pre-tax NPV (5% discount rate) of $621 million, an IRR of 27.6%, and a payback period of 2.95 years.
Clifton is pleased with the drill results, and has continued its drill program for 2013 with the goal of upgrading and expanding the current resources.
Clifton has also initiated the process of collecting a bulk sample that will be sent to SGS Lakefield for additional metallurgical testing. The results from the 54 drill holes from 2012, post cut-off date for the PEA, and the current drill holes from the 2013 program will be incorporated in a future update of the resource component for the pre-feasibility report set to begin in early 2013 and expected to be completed in March 2014.
This new Resource Estimation of the Duparquet Project will include the Beattie, Donchester, Central Duparquet and Dumico properties, as well as the Beattie tailings. Clifton is continuing an extensive resampling program and QA/QC review of historical holes on the Dumico property, located approximately 1 km to the east of the Central Duparquet pit shell.
Technical Information and Qualified Persons
Diamond drill holes are drilled to recover NQ size core. The core boxes are sealed and delivered to the company's core logging facilities on site at the end of each shift where they are photographed, logged and sampled. Core samples are sawed in half, bagged and sealed 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 duplicates 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 reassayed using a gravimetric and/or pulps and metallic procedure. All gold results reported are cut, with assays greater than 25 grams per tonne cut to 25 grams.
The Company's exploration team designed and executed the 2012 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.
