The Wanipigow River Plutonic Complex, which forms the northern boundary of the Rice
Lake greenstone belt, is composed predominantly of hornblende and biotite-bearing
quartz dioritic, granodioritic and locally quartz monzonitic intrusions and gneisses.
Several large masses of gabbro are also present in the region. Historically this area has
been considered to be basically devoid of significant areas of volcanic terrain, however,
the Wallace Lake - Siderock Lake area (Theyer, 1985 and Sasseville, 1999) are definitely
underlain by Garner Lake Assemblage volcanic rocks. Howe’s site visit (2000) to the
adjacent Wildcat’s Poundmaker property also indicates that the gold-bearing quartz vein
is hosted within carbonate altered mafic volcanic rocks rather than quartz diorite and fine
grained mafic dykes as suggested by previous data (Richardson and Ostry 1996 citing
Weber 1971)....Traps7
