The Ryan Creek prospect was identified in 2003 and is the central zone of a 6 kilometre long Pine West to Pine North porphyry zone that parallels the Pine-Fin-Tree porphyry copper-molybdenite-gold deposits 5.0 kms to the south. Both porphyry belts are located in the Toodoggone region in north central British Columbia and are 100% owned by Cascadero Copper, subject to a NSR.
The Ryan Creek showing consists of a magnetite bearing hornblende monzonite intrusion that underlies Toodoggone formation lithic fragmental volcanics. The outcrop is mineralized by disseminated and stringer sphalerite, chalcopyrite and molybdenite. The overlying volcanics situated on Nub Mountain host high-grade gold and silver mineralization in both low- and high- sulphidation epithermal mineral occurrences 300 metres higher in elevation. This intrusive body has been mapped and includes the Pine-Tree-Fin area and to extends to the newly discovered Sofia copper-gold porphyry occurrence 14 km north, which is controlled by Stealth Minerals.
The 2005 drill program completed 4 BQ sized core holes totalling 918 meters. The holes tested a 200 by 400 metre portion of the prospective geology with holes spaced at roughly 150 meters. The holes intersected fracture fillings and disseminations of sphalerite with minor chalcopyrite, pyrite and gold.

Core drilling at Ryan Creek displayed alteration and mineralization consistent with that of the outer zone of a larger porphyry system. The potassic-copper-gold core to the system could be located 2,000 metres to the north east of the Ryan Creek drill holes at Pine North, which is high-grade copper, molybdenum and gold soil geochemical anomaly that coincides with an Induced Polarization anomaly. The Ryan Creek data provides compelling evidence that suggests the un-drilled large-scale Pine North prospect is a high-priority target.
Assaying was conducted by Eco-Tech of Kamloops, BC. All assays are 30 gram fire assays with 28-element ICP. Field work was under the direction of by Dave Kuran, P. Geo., who also compiled and interpreted the data and who is the qualified person for the Company.
