JASPER MINING CORPORATION REPORTS HIGH GRADE VALUES ON TOP TEN HOLES ON THE ISINTOK PROPERTY
Jasper Mining Corporation (the “Company”) (JSP: TSX-V) is pleased to announce the top ten assay results from the 2005, 2006 and 2008 Diamond Drill Programs on its 100% owned Isintok property. The property comprises 3007 ha (7430 acres or approximately 11.6 square miles), covering the drainage divide between McNulty and Isintok Creeks. The property is located west of the Okanagan Valley in southcentral British Columbia, approximately 30 km west of Penticton and 20 km north of Hedly.
A total of 54 drill holes have been completed by Jasper on the property. The drill holes have shown that the length is 1200 meters north-south, width is 600 meters east-west and 300 meters deep. A total of 22,000 meters of diamond drill holes have been drilled and all holes in the program are mineralized with some high grade in every hole. The Isintok deposit remains open in all directions including to depth.
Core in each of the sampled intervals was split, with one half submitted for analysis and one half retained for subsequent analysis. The core was submitted to Acme Analytical Laboratory Ltd. in Vancouver, BC for Group 1DX analysis. Samples returning in excess of 10,000 ppm Copper (Cu) were re-submitted for Group 7AR analysis. Samples that returned Molybdenum (Mo) results greater than 2,000 ppm were re-submitted for Group 7KP.
The analytical results and tables in this news release were prepared by the Company’s consultants, TerraLogic Exploration Inc., of Cranbrook, BC and the assays by Acme Labs of Vancouver, BC.
Isintok Intersections – Highlights
The following table is a compilation of high grade analytical results for copper, molybdenum, gold, and silver from the 2005, 2006, and 2008 Isintok DDH programs. Intervals were selected based on cutoffs of >3.0m length @ >0.1% Cu, and a dilution width of 20m.
Where:
CuEq = [[Cu% * 20 * $Cu] + [ Mo% * 20 * 1.67 * $Mo] + [Au(g/t) * ($Au/34.29)] + [Ag(g/t) * $Ag/34.29]] / [$Cu * 20]
And:
$Au = $1275/oz, $Ag = $22.00/oz, $Cu = $3.40/lb, $MoO2 = $15.50/lb
*Vein intersections are all inclined to core axis, therefore lengths of mineralized intervals are apparent thicknesses only.
The Copper Equivalency prices are all approximately at a 20% discount to current prices.
See the Jasper website (www.jaspermining.com) for a map of the Isintok drill holes.
AMC Consultants of Vancouver, BC have been engaged to prepare a compliant report on the Isintok deposit that could measure overall grade and tonnage.
