Capsule Geology

Granodiorite and quartz monzonite of the Late Cretaceous Scuzzy pluton underlie the area. These rocks have been intruded by late aplite dykes and quartz porphyry plugs and are locally brecciated and/or silicified.

Near the headwaters of an unnamed tributary to Big Silver Creek, these rocks host structurally controlled quartz stockwork veining within an elliptically shaped gossan. Within this gossan, three mineralized zones have been identified as follows: Central Moly, Sericite Fracture and Quartz-Moly Breccia.

Within these zones, molybdenite occurs as coarse-grained rosettes along the selvages of the larger (up to 10-centimetre wide) veins, as disseminations and fine plates in the selvages of the smaller veins and along the walls of interstitial cavities in some breccias. Molybdenite also occurs in association with pyrite(-chalcopyrite) as coatings along tight shears, along sericitic fractures and within zones of quartz-cemented intrusive breccia. Conspicuous molybdenite is restricted to the innermost 200 metres of the Central Moly zone.

Molybdenum values from chip samples range from 0.004 per cent in strongly pyritic rocks to 8.27 per cent across a 10-centimetre wide quartz vein. Sample C-177, across a 50-centimetre wide, rusty- weathering zone hosting pyrite, pyrrhotite, magnetite, chalcopyrite and molybdenum assayed greater than 0.1 per cent tungsten (Assessment Report 11003). The source of the tungsten has not been identified.

In 2005, United Exploration Management Inc. completed rock sampling and IP surveys.

In 2007, Pacific Cascade Minerals Inc. drilled 9 diamond drill holes totalling 2,437.5 metres. One hole returned 0.053 per cent molybdenite over 195 metres, including 0.196 per cent molybdenite over 44.6 metres (Assessment Report 28857).
