Feb 11, 2011 (J Bongfelt) - Geology The prospect is situated within intermediate to felsic pyroclastics of the Lower Wabigoon Volcanics, dominantly consisting of massive, feldspar and quartz-feldspar crystal tuffs intruded by gabbro, diorite, and felsite or porphyritic felsic dikes. (OFR 5723, pg.195)
Feb 11, 2011 (J Bongfelt) - Lithology The majority of trenching and sampling at Fornieri Bay was conducted less than 100 m inland along the east shore of the bay. Although it was difficult to observe geological relationships within the numerous trenches due to poor exposure, the author noted numerous narrow, fracture-hosted quartz veins and veinlets occurring throughout the felsic and intermediate crystal tuff host rocks. Previous descriptions of the quartz veins by Erie Canadian Gold Mines Limited indicate that the majority are fracture hosted, lensoid, and discontinuous (Assessment Files, Resident Geologist's Office, Kenora). At the most extensively trenched zone, gold-bearing, fracture-controlled quartz veins are hosted by a wide quartz porphyry dike intruding felsic crystal tuffs. Moorhouse (1941) indicated that gold values were obtained from four, wide, generally east-trending quartz veins and two large lenticular zones of quartz stringers. The majority of quartz veins and stringers consist of white and blue-gray quartz containing <1% disseminated pyrrhotite, pyrite, minor chalcopyrite and chlorite. Moorhouse (1941) observed small amounts of visible gold and bismuthinite within the larger quartz veins. Host rocks at Fornieri Bay contain <1-5% disseminated pyrrhotite and pyrite. Aleration is not obvious on weathered outcrop surfaces but is well defined in drill core. Host rocks containing disseminated sulphides, hairline fractures, and quartz veining, are pale gray to buff brown-gray, due to sericitization, calcium carbonate alteration, and moderate silicification. Feldspar fragments in the crystal tuffs are sericitized and less distinguishable in the alteration zones. Many of the fractures and quartz veins are surrounded by narrow, alteration haloes in which sericitization and carbonatization impart a pale gray appearance to the host rocks. (OFR 5723, pg. 195)

Feb 11, 2011 (J Bongfelt) - Mineralization 'The best assay from ten chip samples, taken by the author, J.R. Parker, from the quartz veins and stringer zones exposed in the main trenched area was 280 ppb gold. Grab samples from shear zone-hosted quartz veins in test pits north of the main trenched area assayed 165 ppb and 980 ppb gold.' 'Sulphide-rich samples of fractured rhyolite, containing narrow quartz stringers, taken from a hole drilled in the vicinity of the old trenches in 1982, assayed 0.057 ounce gold per ton over 10 ft., and 0.374 ounce silver per ton and 0.65% copper over 5 ft. Holes drilled south and west of the trenches in 1983, intersected relatively narrow diorite and gabbro dikes intruding rhyolitic flows and felsic tuffs hosting wide intervals of abundant (4-5%) pyrite, pyrrhotite, and chalcopyrite in quartz-carbonate veinlets, along fractures, and disseminated throughout relatively undeformed host rocks. These wide sulphide-rich intersections were found to host anomalous gold mineralization assaying 0.013 ounce gold per ton over 150 ft. and 0.023 ounce gold per ton over 178 ft., including a smaller intersection of 0.036 ounce gold per ton over 70 ft. In 1985, further drilling intersected more sections of anomalous gold, with one intersection assaying 0.24 ounce gold per ton over 3.5 ft. and 0.22 ounce gold per ton over 10 ft. (Assessent Files, Resident Geologist's Office, Kenora). It should be noted the'holes drilled by Kamio Gold Mines Ltd. were drilled down dip and the holes drilled by Raleigh Resources Ltd. were drilled parallel to the strike of stratigraphy and structures such as shear zones.'
