M3 Metals Corp.: M3 Metals Prepares for Trenching at Its Block 103 Iron Ore Project Vancouver, British Columbia--(Newsfile Corp. - May 12, 2021) - M3 Metals Corp. (TSXV: MT) (FSE: X0VP) ("M3 Metals" or the "Company") is pleased to provide an update on its upcoming planned trenching program on its 100% owned Block 103 Iron Ore Project in Newfoundland and Labrador, Canada. The Company has selected 10 priority targets to test for Direct Shipping Ore ("DSO") mineralization. Target selection was based on reanalysis of the extensive drilling and numerous airborne and ground based geophysical surveys including detailed magnetic and gravity surveys. The Company is targeting pockets of DSO within and surrounding its primary 7.2 Billion tonne Taconite (Magnetite Iron) resource (see news release dated Feb 4, 2013). Of immediate interest is a zone of high-grade haematite mineralization intersected in hole 64 (see below) showing the potential for DSO within and around the resource on the Block 103 property. This mineralization was intersected near surface from 26.82 metres to 32.92 metres and represents one of the initial target areas for the currently planned trenching program.
