Orestone Mining Corp. (TSX Venture Exchange-Symbol: ORS) (the “Company”) has received assays from recently completed drilling on the Company’s Captain copper-gold porphyry project in North Central BC. The program consisted of three diamond drill holes totaling 642 metres. Holes C13-01 and C13-02 were drilled 400 metres respectively NW and SE of significant potassic alteration and copper gold mineralization intersected in previous holes C12-05 and C11-01. Hole C13-03 was drilled in the center of the Admiral target, a large magnetic high measuring 1000 metres by 1500 metres located 800 metres north of holes C12-05 and C11-01.
Hole C13-03 intersected an unaltered and un-mineralized post mineral alkali gabbro dyke from the bedrock contact at 78.9m to 280.0m. At a depth of 204.9m to 207.9m a xenolith fragment of highly potassic-sericite altered monzonite porphyry was intersected which assays 0.226% copper and 1.90 g/t gold over three metres. The post mineral dyke is interpreted to measure 50 metres in thickness and 1000 meters in strike length and the xenolith fragment or rafted block is thought to have been transported from immediate adjacent rocks.
Hole 13-02 was drilled at an Azimuth of -70 NE across a strong magnetic anomaly and intersected two sections of potassic-sericite altered volcanic and monzonite dykes separated by a section of post mineral andesite dykes. The first mineralized dyke was intersected from 32.4m to 66.4m for an interval of 34m with an average grade of 0.073% copper and 0.20 g/t gold while the second mineralized dyke was intersected from 121.3m to 170.1m for an interval of 48.8m with an average grade of 0.055% copper and 0.35 g/t gold.
Hole C13-01 intersected intensely quartz-sericite-pyrite altered volcanics on the south margin of the Admiral target averaging 183 ppm Cu and 52 ppb Au.
The highlight of the summer 2013 drilling program was the intersection of the monzonite porphyry xenolith fragment within a post mineral dyke near the center of the Admiral magnetic target. A large IP target surrounding the dyke is interpreted to be the source of the xenolith; future drilling south and north of the dyke is recommended.
The drill core was transported from the drill site to a secure warehouse facility in Fort St. James where it was logged with sampled intervals halved by diamond saw. A total of 55 samples were collected, generally on 3.05 meter intervals and shipped by secure transport to Acme Labs sample preparation facility located in Smithers, B.C., for analysis in Vancouver, B.C. The remaining core is stored at the warehouse site. Gary Nordin P.

The 100 percent owned Captain Project hosts a large gold-copper porphyry system measuring seven by fourteen kilometers located 41 kilometers north of Fort St. James, British Columbia and approximately 30 kilometers south of the Mt. Milligan gold-copper deposit. The project features relatively flat terrain, moderate tree cover and an extensive network of logging and Forest Service roads suitable for exploration year around. The Company now has all permits in place to facilitate 75 line kms of geophysics with 58 sites approved for drilling. The Mt. Milligan deposit is currently under construction by Thompson Creek Metals Company Inc. as a large open pit mine and processing facility.
