Mar 23, 2018 (Therese Pettigrew) - Sampling by New Fortune Mines in 1957 indicated 32.1% Fe across 30 feet, and 32% Fe across 10 feet. Relatively pure magnetite occurs in bands in composite zones which are interbedded with greenstone formations (AFRI 52A05NW0015). Seven NE-trending, discontinuous zones of magnetite quartz (jasper) iron formation with some amphibole and intercalated amphibolite and greywacke. The zones have lengths from 91.4-731.5 m, occur within Archean volcanics, and are intruded by mafic bodies (Shklanka, 1968).
