Jun 26, 2013 (A Wilson) - The hole penetrated through 55 m of overburden before collaring in a sequence of weakly to strongly cabonitized mafic metavolcanic flows and related fragmental rocks. These rocks also exhibit some sericite and chlorite alteration. From 148.4 to 149.8 m the hole cut a quartz carbonate vein carrying minor pyrite, chalcopyrite and hematite.
