The China Creek area is underlain by andesitic rock of the Cretaceous Kasalka Group. These are intruded by granodioritic rocks of the Upper Cretaceous Kasalka Plutonic Suite

The China Creek zone was tested by Induced Polarization in 2005 and diamond drilling (3 holes) in 1991. Sub-economic concentrations of copper and molybdenum were identified in granitic rocks. Drill logs describe mineralization as disseminated and/or quartz vein-related and/or fracture-related pyrite, chalcopyrite, hematite, molybdenite and magnetite. Some mineralization is related to potassic alteration.

The drill program in the China Creek area successfully tested the large copper soil geochemical anomaly discovered during the earlier programs. The anomaly had been tested by several bulldozer trenches; interesting values were returned on samples taken in the trenches.

The next two holes drilled on the China Creek copper soil anomaly were successful in intersecting an altered feldspar porphyry monzodiorite or diorite, carrying values in copper and molybdenum. The intrusive was propyllitically altered with epidote, chlorite, magnetite, and hematite.

The highest 3 metre intersection of the three holes appears to be 0.175 per cent copper, 0.007 per cent molybdenum and 7.5 grams per tonne silver (Assessment Report 22092)
