Mineros Announces Correction to Dividend Disclosure

(all amounts expressed in U.S. dollars unless otherwise stated)

MEDELLIN, March 28, 2024 - Mineros S.A. (TSX: MSA) (CB: MINEROS) ("Mineros" or the "Company") is providing a correction to the disclosure on the 2023/2024 dividend information contained in its press release of March 27, 2024. The information below replaces and supersedes the prior 2023 Dividend disclosure in its entirety.

At the Meeting, the General Shareholders Assembly approved the distribution of the Company's profits set forth in Table 1 below, including, in respect of each common share, an annual ordinary dividend of $0.075, payable quarterly, in four equal quarterly installments of $0.01875, and an extraordinary dividend of $0.025, payable in four equal quarterly installments of $0.00625, representing a total distribution of $0.10 per share per annum, or $29,973,740 in total for the year, calculated based on the number of shares issued and outstanding as of the close of business on March 26, 2024. This represents an increase of 43.8% compared with last year's dividend.

Table 1. Shareholder-Approved Profit Distribution for the Fiscal Year Ended December 31, 2023.

The Canadian record dates and Canadian/Colombian payment dates are set out in Table 2.

Table 2. Canadian Record Dates and Canadian/Colombian Payment Dates.

Payment of each dividend amount will be made on each payment date in U.S. dollars, which may in some cases be converted into local currency at the official foreign exchange rate on the date of each payment. In general, under the Colombian Tax Code, dividends and distributions out of profits taxed at the corporate level to non-resident shareholders are subject to a 10% withholding tax. However, the 10% withholding tax is reduced to 5% under the Tax Treaty between Colombia and Canada if the shareholder is a company with a participation larger than 10% in the Colombian company distributing the dividend. The reduced tax rate is only applicable if the beneficial owner of the dividend is a Canadian resident company. If the beneficial owner is an individual, no reduced tax rate will apply.

The approved dividend is in line with the Company's dividend policy, which is to pay in dividends at least 15% of the net income of the prior fiscal year, provided that this allows, in good faith, to maximize the long-term value of the Company.
