Jul 31, 2017 (A Wilson) - Keewatin sediments cut by Haileyburian lamprophyre dikes are intruded by the Nipissing diabase sill. The diabase lies on the north-west flank of the Peterson diabase basin. Cobalt sediments, about 12 ft. thick, underlie the diabase in underground workings in the north-west part of the property. The Lower diabase-Keewatin contact is exposed on 745 ft. level and is marked by steep rolls and large inclusions of Keewatin. The southwest portion of the Webb claim is crossed by the northwest trending Cross Lake Fault and Cross Lake olivine diabase dike. The Main Vein, exposed on 745 ft. level, was the only producing vein. It is closely associated with a west-northwest striking zone of faulting and is in proximity to a lamprophyre dike. The productive part of the vein was in Keewatin rock and near the bottom contact of the diabase.
