Jan 21, 2010 (J Bongfelt) - Within the pit, a 2m wide shear zone of pyritic basalt, quartz veins and granite dikes, were located with an orientation of 280°/058°S. Several samples were collected from north to south. At the north end of the pit, a sample of black, fine-grained, massive basalt with trace-2% Pyrite was taken. A 30cm zone of >50% white quartz veins, paralleling the shear orientation (280°), was located in this sheared basalt. A 50cm wide zone of highly sheared basalt +/-porphyry/granite fragments with>10% sulphides of pyrite and minor chalcopyrite -sphalerite «2%). See sample AR03022. At the south face of the pit. a medium-grained, tectonised felsic rock (granite or quartz feldspar porphyry) was located. This felsic unit is parallel to subparallel to the shear direction and does contain up to 10% basalt fragments. As we continued eastward toward the road, we examined a semi-continuous outcrop 10m east of the pit. A 2m rock face was examined. At the base of this face, a 30cm thick zone of 30-50% semi-massive sulphides (pyrite) with 2-4% chalcopyrite and 1-2% sphalerite.Above this sulphide unit, a fine-grained, grey to green, sheared, chloritic basalt with 2-5% pyrite with a foliation of 262°/38°S. Continuing southeast for 600m on the secondary road and we located an oxidized outcrop. This outcrop consisted of a massive basalt with trace sulphides and is highly magnetic, indicating the presence of magnetite. (Kenora Property Visit File, 52F09NW, Naumann Property)
