May 08, 2015 (Therese Pettigrew) - The Marshall Lake property area comprises of a sequence of Neo-Archean calcalkaline metamorphic-volcanic rocks and volcanogenically-derived clastic and chemically-derived metasedimentary rocks within the Marshall Lake Series, an accumulation of felsic to intermediate bimodal rocks over 9000 m thick. The property is situated on the southern limb of a regional antiformal fold at the top of the Marshall Lake Series and is a deformed acidic metavolcanic complex. It is comprised of a large dacitic volcanic pile located on the northern margin of the Onaman-Tashota greenstone belt within the eastern portion of the Wabigoon Subprovince. The geology of the area is dated at 2739 Ma (Nielsen et al., 2010).
