Dec 21, 2017 (C Ravnaas) - The general rock types found in the Mine Center area and on the Cat-Key property consists of bi-modal mafic to felsic volcanic rocks, dominantly massive and minor pyroclastic flows, with lesser units of interbedded tuff, lapilli tuff and chemical and sedimentary rocks. These rocks have been intruded by ultramafic, mafic, intermediate and felsic intrusive rocks. The East-West and northeast striking Mine Center Meta-Volcanic Belt is bonded to the north by the East-West Quetico Fault, located at its northern margin of the metavolcanic belt. Along its southern margin, it is bounded the east-northeast striking Seine Bay-Rainy River Fault Zone. These two major orogenic events and possibly other subsequent events have played an important role in the preparing rock features for localizing gold mineralization within lithologically controlled sheared, carbonitized and silicified in rocks within the Mine Center area from page 37 of NuVision Resources 2016 DDH report AFRO 2.57161 and KAF 52C10NE PPP4.
Dec 21, 2017 (C Ravnaas) - Altered and sheared contacts between lithological units in the Mine Centre area appear to host known old mineralization, especially within the felsic volcaniclastic units, such as interbedded tuff, lapilli tuff and flow top breccia’s within the mafic unit such as that found at the Thompson gold occurrence. These lithologically contrasting units are generally less resistant to deformation and are generally more susceptible to shearing and alteration. Such lithology, when subjected to shearing, provides favourable passage ways for mineralizing hydrothermal gold bearing fluids, which was emplaced after the stratabound copper-zinc base metal mineralization from page 6 of NuVision Resources 2016 DDH report AFRO 2.57161 and KAF 52C10NE PPP4.
