The Ryan occurrence is located about 206 kilometres north-northwest of the community of Germansen Landing.

The Ryan 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 Plutonic Suite.

Outcrop on the Ryan creek prospect is comprised of intensely sheared, quartz-sericite-pyrite altered granodiorite to quartz monzonite of the Black Lake Plutonic Suite, with 1 to 10 per cent pyrite and trace chalcopyrite, sphalerite, galena, and molybdenite and associated weakly anomalous levels of copper, zinc, silver, and gold values. Soil geochemical and induced polarization anomalies add to the prospect and may represent a porphyry copper hydrothermal system approximately 1.5 by 3.5 kilometres in dimension.

Prospecting in 2003 discovered mineralized outcrop in Ryan Creek. Stealth Minerals 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 Pine North (094E 252) and Ryan Creek mineralized zones. Geophysics also identified two areas within this large-scale zone with high values which were the initial locations for drilling in 2005. Diamond-drill holes DH RC05-01 to RC05-04 are located 200 to 350 metres southwest of Ryan Creek (Assessment Report 28071).

Ryan Creek drilling had significant zinc values in all four holes which suggests that the drillholes were on the periphery of a porphyry deposit. A porphyry target was postulated as existing closer to the Pine North (094E 252) target area where there is a high induced polarization anomaly. Sphalerite appears in all four holes and was found to occur along fractures often with quartz and calcite and occurs in greater quantities than chalcopyrite or molybdenite. Drillhole C05-03 yielded 0.05 per cent copper and 0.12 per cent zinc over 20 metres (104 to 124 metres); a zone where the quartz monzonite hostrock is clay gouged and pyrite plus chalcopyrite veins are up to 2 centimetres wide (Assessment Report 28071).

During the 2006 field season, Cascadero Copper Corp. completed a 49-sample mobile metal ion geochemical sampling program between Ryan Creek to the western edge of the Pine North prospect, a distance of 2.4 kilometres.

In 2007, a small helicopter-supported drilling program was employed to test a mobile metal ion soil anomaly in Pine North (Assessment Report 30200). The Ryan prospect, identified by Stealth Minerals Ltd. prospecting in 2003 and drilled in 2005, was interpreted as the zinc-rich periphery of a porphyry copper-molybdenum deposit centred some 2 kilometres to the northeast at Pine North.
