/NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES./

MEDELLIN, Colombia, Nov. 19, 2021 /CNW/ - Mineros S.A. (TSX: MSA) (CB: MINEROS) ("Mineros" or the "Company"), a Latin American gold mining company headquartered in Medellin, Colombia, is pleased to announce the closing of its previously announced initial public offering (the "Canadian Offering") in Canada, and its over-subscribed concurrent public offering in Colombia (the "Colombian Offering"). Pursuant to the Canadian Offering, Mineros issued 22,222,223 common shares of the Company ("Common Shares") at a price of US$0.90 (being C$1.1207) per Common Share (the "Offering Price") for total gross proceeds of approximately US$20 million (being approximately C$24.9 million). Pursuant to the Colombian Offering, Mineros issued 12,777,777 Common Shares at the Offering Price, including 1,666,666 Common Shares following the exercise in full by the Colombian underwriter of its over-allotment option, for total gross proceeds of approximately US$11.5 million.

The Common Shares will commence trading today on the Toronto Stock Exchange ("TSX") under the symbol "MSA". The Common Shares are also listed on the Colombian Stock Exchange (Bolsa de Valores de Colombia or "BVC") under the symbol "MINEROS:CB".

"Today is a historic milestone, as Mineros becomes the first Colombian company to have its common shares directly listed on both the Toronto Stock Exchange and the Colombian Stock Exchange," said Andrés Restrepo, President and CEO of Mineros. "With this dual listing we look forward to working with the Canadian investment community to expand our shareholder base into the North American market. Our Company has a long and profitable history of building and operating gold mines in Latin America, built on the fundamental principle that we operate for the well-being of everyone."

The Company expects to use the net proceeds from the Canadian Offering and the Colombian Offering to repay all of the existing indebtedness incurred in May 2021 in connection with the consolidation of a 100% interest in its Luna Roja exploration target in Nicaragua, and to pursue its growth strategies.

The Canadian Offering was led by Scotiabank and Sprott Capital Partners LP as co-lead underwriters and joint bookrunners (together, the "Underwriters"). Mineros has granted the Underwriters an over-allotment option (the "Over-Allotment Option") to purchase up to an additional 3,333,334 Common Shares at the Offering Price for additional gross proceeds of US$3,000,000 if the Over-Allotment Option is exercised in full. The Over-Allotment Option can be exercised for a period of 30 days from the date of the closing of the Canadian Offering.

The Colombian Offering was authorized by the Superintendency of Finance by Resolution 1292 dated as of November 4, 2021, and made through Corredores Davivienda S.A., Comisionista de Bolsa, as underwriter (the "Colombian Underwriter").

Gowling WLG (Canada) LLP in Canada and DLA Piper Martinez Beltran in Colombia acted as legal counsel to Mineros, and Fasken Martineau DuMoulin LLP acted as legal counsel to the Underwriters.

The Common Shares have not been, nor will they be, registered under the United States Securities Act of 1933 (the "U.S. Securities Act") or any state securities laws. Accordingly, the Common Shares may not be offered or sold in the United States unless an exemption from the registration requirements of the U.S. Securities Act is available and such offer or sale is made in compliance with any applicable state securities laws. 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 these securities, in any jurisdiction in which such offer, solicitation or sale would be unlawful. No securities regulatory authority has either approved or disapproved of the contents of this news release.
