Vancouver, British Columbia, September 23, 2019 – Marimaca Copper Corp. (“Coro” or the “Company”) (TSX: COP) announces that, as a result of a review by staff of the Ontario Securities Commission, it wishes to clarify the nature of certain reports and documents that were posted on or linked from the Company’s website between May 5, 2019 and September 20, 2019.

During this period, the Company made available on its website analyst notes and research reports that were prepared by third party advisors to the Company. These reports should not have been made available on the Company’s website and have since been removed. Certain sections of these documents included economic information, technical analysis and mine models pertaining to the Company’s Marimaca Project that were prepared based on such advisors’ own analysis. Though the Company did not author these reports or produce these third party models, the Company acknowledges that technical information was contained in these documents that is not supported by the Company’s independent technical report prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101). The Company does not endorse the technical contents of any posted document to the extent that such contents are not supported by the Company’s current NI 43-101 technical report in respect of the Marimaca Project, and any such information should not be relied upon. The Company’s current NI 43-101 technical report on the Marimaca Project is available on SEDAR at www.sedar.com under the Company’s profile.
