The Pine North occurrence is located on the northwest side of Finlay River about 208 kilometres north-northwest of the community of Germansen Landing.

The Pine North area is underlain by volcanics and derived sediments of the Lower Jurassic Toodoggone Formation (Hazelton Group). These are intruded by multiphase granodiorite and quartz monzonite plutons of the Early Jurassic Black Lake Suite.

The Pine North showing is extensively covered by glaciofluvial deposits, is densely vegetated, and exhibits very sparse rock outcrop. The showing was discovered by soil geochemistry in 1992. Following the prospecting discovery of copper-zinc-molybdenum-gold mineralization in a canyon of Ryan Creek in 2003, prospecting and geochemical sampling was focussed on this showing and only minor exploration was done on Pine North until 1996 when a mobile metal ion (MMI) soil geochemical line was run from Ryan Creek northeastward through Pine North.

The Ryan Creek occurrence (094E 243) 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-molybdenum-gold deposits 5.0 kilometres to the south. Both porphyry belts are located in the Toodoggone region in north-central British Columbia.

Mineralized outcrop is sparse over the part of the Pine North zone that shows the best geochemical response, i.e., the lower slopes of the hills bordering the northwest side of Finlay River. Hostrocks are monzonite and quartz monzonite, with lesser amounts of Toodoggone andesitic tuff. Hostrocks commonly are veined by narrow fracture-fillings of quartz-epidote-chlorite, also veinlets of calcite and gypsum. Pyrite, magnetite and hematite are common vein minerals with quartz-calcite, or fill fractures and shears with little or no gangue. Chalcopyrite and sphalerite are less common. Hostrocks are either fresh or weakly propylitized.

Prospecting in 2003 discovered mineralized outcrop in the Ryan Creek area about 1.5 kilometres to the west-southwest of Pine North. The company conducted soil geochemistry and geophysics over the whole area, which established a mineralized area 1000 metres north-south and 4000 metres east-west essentially connecting the two mineralized zones. Geophysics also identified two areas within this large-scale zone with high values; these are the initial targets for future drilling.

In 2007, Cascadero Copper Corporation drilled diamond-drill hole PN-07-01 in the Pine North zone. The hole intersected 67.7 metres of monzonite porphyry that showed weak propylitic alteration and a few fractures mineralized with chlorite-epidote-calcite and pyrite. A 1.5 metre drill core sample at 43.5 to 45.0 metres assayed 0.0425 per cent copper (Assessment Report 30200). Monzonite porphyry has a chilled contact against medium-grained biotite-hornblende quartz monzonite. Below the contact, quartz monzonite contains disseminated pyrite and a magnetite-hematite vein. Fractures are filled with quartz-epidote-chlorite plus/minus calcite and gypsum. Several shears and fractures from 98.5 to 103 metres are mineralized with quartz-chlorite-epidote-pyrite. A 1-metre shear and quartz breccia at 103.5 metres assayed 1.8 grams per tonne silver (Assessment Report 30200). Near the end of the hole, at 135 metres, a 10-centimetre shear zone with quartz breccia and quartz-chlorite-K-feldspar-pyrite mineralization assayed 0.071 per cent copper (Assessment Report 30200).
