The Paul mercury showing is on the hillside west of Relay Creek, 1 kilometre northwest of the mouth of North Cinnabar Creek. The showing is within a panel of andesite breccia, chert pebble conglomerate and volcanic pebble conglomerate of the Upper Cretaceous Silverquick Conglomerate. This panel is thrust over chert and greenstone of the Mississippian to Jurassic Bridge River Complex (Group). Cinnabar occurs as veinlets and disseminations together with carbonate minerals, in carbonatized and fractured Silverquick Conglomerate rocks.
