Jul 07, 2010 (A Wilson) - The conglomerate is comprised of large boulders in the southwestern part of the property. Argillite to greywacke is the dominant lithology elsewhere on the property. The underlying metavolcanics are described as fractured and containing numerous mineralized quartz veins. Biotite schist also was described in the drill logs. The metavolcanics have been intruded by narrow lamprophyre dikes. The quartz-calcite veins are narrow, rarely wider than 2.5 cm.
