TriMetals Mining Inc. (TSX: TMI) (OTCQX: TMIAF) (the “Company” or “TMI“) is pleased to announce that in connection with its recently closed brokered private placement for gross proceeds of $3.5 million (the “Offering“) announced in its news release of June 2, 2017, the syndicate of agents led by BMO Capital Markets and including PI Financial Corp. and GMP Securities L.P. (collectively, the “Agents“) exercised the agents’ option granted by the Company and have arranged for the purchase of an additional 1,458,270 units (the “Additional Units“).
