Presentation on Marimaca to Fexmin Sergio Rivera, VP Exploration, October 2018, Santiago
DISCLAIMER & FORWARD LOOKING STATEMENTS This presentation includes certain forward-looking statements about future events and/or financial results which are forward-looking in nature and subject to risks and uncertainties. Such forward-looking statements or information, including but not limited to those with respect to the development of the Marimaca project, metal prices, metallurgical results and resource estimates, involve known and unknown risks, uncertainties, and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements or information. Forward-looking statements include without limitation, statements regarding the company’s plans, goal or objectives and future completion of mine feasibility studies, mine development programs, capital and operating costs, production, potential mineralization, resources and reserves, exploration results and future plans and objectives of Coro Mining Corp. Forward-looking statements can generally be identified by the use of forward-looking terminology such as “may”, “will”, “expect”, “intend”, “estimate”, “anticipate”, “believe”, or “ continue” or the negative thereof or variations thereon or similar terminology. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause results to differ materially from expectations include risks associated with mining generally and pre-development stage projects in particular. The company is an exploration, development & mining company. Many references to resources and other geological and technical information contained herein have not been verified by an independent expert and are either not in accordance with the requirements under National Instrument 43-101 or have not been prepared in accordance with a preliminary or final feasibility study. Potential investors should conduct their own investigations as to the suitability of investing in securities of Coro Mining Corp. The potential target tonnage and grade noted for the Marimaca project are conceptual in nature as there has been insufficient exploration to define mineral resources, and it is uncertain if further exploration will result in these targets being delineated as mineral resources. Unless otherwise indicated, Coro has prepared the technical information in this presentation (“Technical Information”) based on information contained in the technical reports and news releases (collectively the “Disclosure Documents”) available under Coro Mining Corp.’s company profile on SEDAR at www.sedar.com. Each Disclosure Document was prepared by or under the supervision of a qualified person (a “Qualified Person”) as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators (“NI 43-101”). For readers to fully understand the information in this presentation, they should read the Technical Reports (available on www.sedar.com) in their entirety, including all qualifications, assumptions and exclusions that relate to the information set out in this presentation which qualifies the Technical Information. Readers are advised that mineral resources that are not mineral reserves do not have demonstrated economic viability. The Disclosure Documents are each intended to be read as a whole, and sections should not be read or relied upon out of context. The Technical Information is subject to the assumptions and qualifications contained in the Disclosure Documents. All figures are quoted in US dollars unless otherwise stated. Sergio Rivera, Vicepresident Exploration CEO of Coro Mining Corp, a geologist with more than 35 years of experience is the Qualified Person for the purposes of NI 43-101 and has approved this written disclosure. All Dollar amounts in this presentations are US Dollars unless otherwise stated. 2
