Marimaca Copper Announces Overnight Marketed Equity Financing

/NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES/

VANCOUVER, Nov. 17, 2020 - Marimaca Copper Corp. ("Marimaca Copper" or the "Company") (TSX: MARI) is pleased to announce that it has filed a preliminary short form prospectus in connection with an overnight marketed offering (the "Offering") of units (the "Units") of the Company for gross proceeds of approximately CDN$20 million, at a price per Unit to be determined in the context of the market. The Offering will be conducted through a syndicate of underwriters led by Canaccord Genuity Corp. (collectively the "Underwriters").

Each Unit will consist of one common share in the capital of the Company (each a "Common Share") and one-half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant shall entitle the holder to acquire an additional Common Share at any time for a period of 24 months following the closing of the Offering.

The size and pricing of the Offering will be determined in the context of the market at the time of entering into a definitive underwriting agreement between the Company and the Underwriters. The Company has granted the Underwriters an option (the "Over-Allotment Option") to purchase up to an additional 15% of the Units of the Offering on the same terms exercisable at any time up to 30 days following the closing of the Offering, for market stabilization purposes and to cover over-allotments, if any.

Closing of the Offering is expected to occur on or about December 2, 2020 and is subject to certain conditions, including regulatory approval, including that of the Toronto Stock Exchange.

The net proceeds of the Offering shall be used to repay outstanding indebtedness of approximately $8.3 million under the Company's working capital facility and to advance the Company's Marimaca Project.

The Units to be issued under the Offering will be offered by way of a short form prospectus in each of the provinces of Canada, other than Quebec, and may be offered in the United States on a private placement basis pursuant to an exemption from the registration requirements of the United States Securities Act of 1933, as amended, and applicable state securities laws, and certain other jurisdictions outside of Canada and the United States.

This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. This news release does not constitute an offer of securities for sale in the United States. The securities being offered have not been, nor will they be, registered under the United States Securities Act of 1933, as amended, and such securities may not be offered or sold within the United States absent registration under U.S. federal and state securities laws or an applicable exemption from such U.S. registration requirements.
