Mineros Files Preliminary Prospectus for Initial Public Offering in Canada and Colombia

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

STATES/

Medellin, Colombia – September 17, 2021 – Mineros S.A. (BVC: MINEROS) (“Mineros” and/or the

“Company”) announced today that is has filed, and obtained a receipt for, a revised preliminary

prospectus dated September 16, 2021 (the “Preliminary Prospectus”), with the securities regulatory

authorities in each of the provinces of Canada, other than Québec, for a proposed initial public offering

of common shares (the “Offering”). The gross proceeds of the Offering are expected to be US$25 million.

The number of common shares to be sold and price per common share have not yet been determined.

The Offering will be managed by Scotiabank and Sprott Capital Partners LP (collectively, the

“Underwriters”). Mineros will grant the Underwriters an over-allotment option, exercisable for a period

of 30 days from the date of the closing of the Offering, to purchase up to an additional 15% of the total

number of common shares to be sold pursuant to the Offering.

Mineros President and CEO Andrés Restrepo Isaza commented “Mineros is a well-established Latin

American gold mining company with a long history of delivering growth and strong dividends to investors

on the Colombian Stock Exchange. Filing our Preliminary Prospectus is an important step for the

Company’s growth, as we establish ourselves as a multi-asset, mid-tier gold producer ”.

In connection with the Offering, Mineros has applied to list the Common Shares to be distributed under

the Offering, as well as its additional issued and outstanding Common Shares, on the Toronto Stock

Exchange (“TSX”). The Company has also applied for an exemption from the individual voting and

majority voting requirements applicable to listed issuers under TSX policies, on grounds that compliance

with such requirements would constitute a breach of Colombian Regulations which require the directors

to be elected on the basis of a slate of nominees proposed for election pursuant to an electoral quotient

system as more fully set out in the Preliminary Prospectus. Listing is subject to the approval of the TSX

in accordance with its original listing requirements. The TSX has not conditionally approved the

Company’s listing application and there is no assurance that the TSX will approve the listing application.

The Preliminary Prospectus containing important information relating to the Common Shares has been

filed with securities commissions or similar authorities in each of the provinces of Canada, other than

Québec. The Preliminary Prospectus is still subject to completion or amendment. Copies of the

Preliminary Prospectus may be obtained from either of the Underwriters listed above, and will be

available on SEDAR at www.sedar.com. There will not be any sale or any acceptance of an offer to buy

the securities until a receipt for the final prospectus has been issued. No securities regulatory authority

has either approved or disapproved the contents of this news release.

Mineros intends to use the net proceeds from the Offering to fund repayment of the indebtedness

created by the Luna Roja Davivienda Loan and for general working capital. The funds provided by the

Luna Roja Davivienda Loan were used to complete the acquisition by Hemco of the 50% interest in the

Luna Roja Exploration Target not already owned by it and the acquisition of the corresponding interest

in the related joint venture which closed on May 21, 2021.

Today, Mineros has also filed with the Colombian Superintendence of Finance a preliminary prospectus

in respect of a concurrent public offering in Colombia of common shares for gross proceeds of up to

US$10 million (the “Colombian Offering”). The Colombian Offering is being made through Corredores

Davivienda S.A., Comisionista de Bolsa, as underwriter. The offering of the common shares in the

Colombian Stock Exchange ( Bolsa de Valores de Colombia ) pursuant to the Colombian Offering and

the Offering remains subject to the approval of the Colombian Superintendence of Finance.

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

be not 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 by any sale of these securities, in any jurisdiction in which such offer, solicitation

or sale would be unlawful.

Completion of the Offering and the Colombian Offering are subject to the receipt of customary approvals,

including regulatory approvals.

Gowling WLG (Canada) LLP in Canada and DLA Piper Martinez Beltran in Colombia are acting as legal

counsel to the Company, and Fasken Martineau DuMoulin LLP is acting as legal counsel to the

Underwriters.
