Capstone Mining Corp. announced its 70% owned subsidiary Minera Santo Domingo (“MSD”) has entered into a memorandum of understanding (“MOU”) with Puerto Abierto S.A. (“PASA”) a wholly owned subsidiary of Puerto Ventanas S.A. (“Puerto Ventanas”) for Capstone’s Santo Domingo project in Region III, Chile (“Santo Domingo” or the “Project”). During a 90 day period, both MSD and PASA will together explore mutual synergies and regional benefits for the proposed port component of the Santo Domingo Project, Puerto Santo Domingo (the “Port”). The Port is fully permitted and located 100 kms from the Santo Domingo project site. It will be one of only two Cape-size vessel ports in the region, making it an attractive site for bulk shipments and a key asset allowing for broad resource development in Region III of Chile. MSD will allow PASA to study, at its own cost, during a term of 90 days, the Project engineering and conduct a market study. PASA is looking to potentially acquire, construct, operate and maintain the deep-water Port, including financing its development. Once in operation, Santo Domingo will receive preferred service as its volumes will represent a baseload of business for the Port. The MOU also gives PASA 90 days to evaluate the replacement of the 110 km magnetite concentrate pipeline with a railway as part of its rail business, Ferrocarril del Pacifico S.A. (FEPASA). The Santo Domingo project infrastructure that is under consideration in this MOU represents approximately $400 million of the CAPEX identified in the most recent NI 43-101 Technical Report and includes: Marine works including pier; Iron concentrate pipeline from Santo Domingo Mine to Port; Magnetite filter plant and stockpile building; Copper storage building; Ship loading and support facilities.
