Wallbridge Mining Discovers Porphyry Gold-Copper Mineralization on BC Propertyadmin
Wallbridge Mining Company Limited has discovered mineralization within three target areas on their Rogers Creek copper-gold-molybdenum property, in south-western British Columbia approximately 40 kilometres south of Pemberton. The first two targets are defined within a 6 by 2 kilometre area of alteration and gold-copper mineralization with samples in quartz-sulphide veins returning up to 23.1 grams per tonne gold and 232 grams per tonne silver. The third target is defined by silt samples returning highly anomalous gold and silver values up to 2.3 grams per tonne gold and 436 ppb silver. The style of mineralization and alteration is consistent with a porphyry copper-gold-molybdenum system.
The Rogers Creek property was acquired in February 2008 from a local prospector. It comprises 93 claims covering 420 square kilometres of favourable geology. The summer 2008 work program consisted of 1434.6 line kilometres of high resolution helicopter-borne magnetic and VLF surveying, silt (149), soil (307) and rock (446) sampling, and mapping and prospecting. The property is located in an easily accessible area with excellent infrastructure including a major power line along the western edge of the property.
Targets 1 and 2
Airborne magnetic surveying and soil, silt and rock samples anomalous in copper, gold and silver have defined two large zones of alteration and associated gold-copper mineralization within a 6 kilometre by 2 kilometre area. Both these zones are centred on two circular to elongate magnetic lows about 2 kilometres in diameter, which closely correspond to outcrops of highly altered, intrusive breccias. Anomalous silt samples in streams draining Targets 1 and 2 contain up to 800 ppb gold, 835 ppb silver and 73 ppm copper versus background values of approximately 2.5 ppb gold, 20 ppb silver and 15 ppm copper. Quartz-sulphide veins contain gold and silver values up to 23.1 gram per tonne gold, 232 grams per tonne silver, 0.69% copper and 81.4 ppm molybdenum. The style and distribution of alteration and mineralization associated with Targets 1 and 2 are consistent with a porphyry copper-gold-molybdenum environment.
Target 3 is located approximately 4 kilometres to the southwest of Target 2. It was defined by stream sediment samples containing highly anomalous values in gold and silver, quartz-pyrite stockworks exposed along road cuts, and talus boulders of a highly clay-altered intrusive breccia. Anomalous silt samples in streams draining Target 3 contain up to 2.3 grams per tonne gold and 436 ppb silver versus background values of 2.5 ppb gold and 20 ppb silver. Limited rock sampling returned values up to 0.4 g/t gold and 436 ppm copper. Target 3 appears to represent a moderate to high level epithermal vein system consistent with the porphyry copper-gold-molybdenum environment at Targets 1 and 2.
A 38 line-kilometre IP survey is planned for October with line cutting to begin by mid-September. The timing of the IP survey will coincide with a second stage of mapping and prospecting and be followed by a limited program of diamond drilling if weather permits.

Wallbridge Mining Company Limited’s primary focus is the exploration of nickel, copper and platinum group element (“PGE”) deposits in the Sudbury area of Ontario. The Sudbury area hosts the world’s largest concentration of nickel deposits and is currently the most active mining camp in North America. Major joint venture partners in Sudbury include Vale Inco, Xstrata Nickel, Lonmin Plc and Impala Platinum Holdings Limited. Wallbridge also has a major shareholding in Duluth Metals Limited, which has defined a large copper-nickel-PGE resource in the rapidly emerging Duluth Complex base metal camp in Minnesota. Wallbridge is also exploring a large porphyry copper-gold-molybdenum property in south-western British Columbia and has interests in copper-zinc and gold properties in northeastern Ontario.
