Feb 11, 2011 (J Bongfelt) - Geology The Manhattan Occurrence is underlain by a massive, wide, medium-grained gabbro dike intruding intermediate to felsic pyroclastics of the Lower Wabigoon Volcanics. (OFR 5723, pg.240)
Feb 11, 2011 (J Bongfelt) - Lithology A shear zone trending 073º/080ºN extends through a wide gabbro dike and hosts quartz-iron carbonate-calcite-tourmaline veins and stringers containing ?1% disseminated pyrite. The wall rocks are intensely sheared, bleached pale green, and contain abundant iron carbonate, fuchsite, and disseminated pyrite [? 5%] with minor chalcopyrite and associated malachite. The gabbro is porphyritic, containing large [ ? l cm], rounded, green-white, feldspar phenocrysts, round, blue, quartz eyes ( ? 5 mm in size), variable amounts of biotite and up to 5% disseminated magnetite. The property consists of a timbered shaft of unknown depth. (OFR 5723, pg.240)

Feb 11, 2011 (J Bongfelt) - Mineralization A grab sample, taken by the author, of altered, sheared gabbro containing approximately 2% pyrite and 1% chalcopyrite assayed 115 ppb gold and 805 ppm copper, while a sample of altered gabbro containing no sulphides assayed 7 ppb gold and 113 ppm copper. A grab sample, taken by the author, from quartz vein material containing 2% pyrite, assayed 720 ppb gold and 198 ppm copper. (OFR 5723, pg.240)
