Toachi Mining Inc. announced the positive results of the independent Preliminary Economic Assessment for the La Mina VMS Project located in the Province of Cotopaxi, Ecuador. The PEA was prepared pursuant to National Instrument 43-101 (NI 43-101) and has an effective date of March 30th, 2019. A NI 43-101 technical report summarizing the PEA (the Technical Report) will be available on SEDAR no later than June 20th, 2019. All references to currencies herein are in U.S. dollars. The PEA was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). Readers are cautioned that the PEA is preliminary in nature and includes the use of Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the results of the PEA will be realized. The PEA was led by independent resources, mining, metallurgy, processing and environmental consultants, with support from the Toachi technical team. The principal consultants include: SGS Canada Inc., Geological Services (SGS); SGS Lakefield, SGS Bateman, Brian Wolfe and Dr. SimonStrickland Meik. A number of other independent consulting firms and potential vendors also provided information used in the PEA. The cash flow model is based on developing the Upper North zone of deposit, followed by the Lower North zone before mining the South zone of the deposit. The cash flow model encompasses the CAPEX and OPEX costs for mining, processing, tailing, infrastructure, G&A, and environment. The Project has a fifteen-month pre-production development period. Production ceases in year 8.
