(all amounts expressed in U.S. dollars)

MEDELLIN, Colombia, January 22, 2024 /CNW/ - Mineros S.A. (TSX: MSA) (MINEROS: CB) ("Mineros" or the "Company") is pleased to announce that it achieved its production guidance for 2023. Mineros is also pleased to provide its production and cost guidance for 2024.

2023 Full Year and Fourth Quarter Production:

• 250,769 ounces of gold produced for the full year, within the Company's 2023 production guidance range of 239,000 - 262,000 ounces.
• 62,039 ounces of gold produced in the fourth quarter.

2024 Production and Cost Guidance:

• Gold production of 209,000 to 229,000 ounces in 2024, a decrease of approximately 13% over its 2023 guidance, as a result of the sale of the Company's Gualcamayo Property in September 2023.
• Cash cost ("Cash Cost")1 per ounce of gold sold is expected to increase slightly to between $1,180 to 1,270 in 2024 ($1,170 to 1,270 in its 2023 guidance).
• All-in sustaining cost ("AISC") per ounce of gold sold1 is expected to decrease slightly to between $1,430 to 1,530 in 2024 (1,440 to 1,540 in its 2023 guidance).

Andrés Restrepo, President and CEO of Mineros, commented: "We had a strong operational fourth quarter and demonstrated resilience throughout the year. We were able to meet our 2023 production guidance while overcoming the disruptions we had in March at our Nechí Alluvial Property and in July at our Hemco Property. As we move forward, the Company will continue to focus on being a reliable and profitable operator."

Total annual production from all operating units was 250,769 ounces of gold in 2023, meeting the Company's annual production guidance of 239,000 to 262,000 ounces (Table 1).

Table 1. 2023 Fourth Quarter and Full Year Production.

Annual production of 93,757 ounces of gold from the Nechí Alluvial Property was near the higher end of our 2023 guidance and approximately 1% above 2022 production. The increase in production in 2023 relative to the previous year is a result of higher operational efficiencies and 28% higher average gold grade at the Nechí Alluvial Property.

In Nicaragua, total combined annual production of 125,951 ounces of gold met our 2023 guidance and was 5% lower than 2022 annual production. Gold production was impacted by a two-week suspension of the main processing plant at the Hemco Property during the third quarter, to allow for tailings detoxification capacity enhancements at the San José Tailings Dam.

The Company announces 2024 production guidance of 209,000 to 229,000 ounces of gold, a decrease of approximately 13% from 2023 guidance, mainly explained by the sale of the Company's Gualcamayo Property in September 2023 (Table 2).

Table 2. 2024 Production and Cost Guidance

Annual gold production for 2024 at the Nechí Alluvial Property in Colombia is expected to increase slightly, to between 86,000 to 96,000 ounces, an increase of approximately 2% from 2023 production guidance. At the Nechí Alluvial Property in Colombia, the Company anticipates Cash Cost per ounce of gold sold to increase from 2023 guidance by approximately 7% to 8% in 2024 and AISC per ounce of gold sold to increase by approximately 9% in 2024 as compared with 2023 guidance.

At the Hemco Property in Nicaragua, the Company anticipates annual production in 2024 of 123,000 to 133,000 ounces of gold, including 90,000 to 98,000 ounces of gold from artisanal production, which is similar to its 2023 production. Our relationship with the artisanal mining community has grown strong throughout the years bringing consistency to mineral purchasing and predictability in our guidance. The Company anticipates Cash Cost per ounce of gold sold to increase by 5% to 6%, and AISC per ounce of gold sold to increase by approximately 7% in 2024, as compared to 2023 guidance.

This news release includes Cash Cost per ounce sold, and AISC per ounce of gold sold, which are non-IFRS ratios that are respectively based on Cash Cost and AISC, which are non-IFRS financial measures. The Company believes that these non-IFRS ratios, in addition to conventional measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company. The non-IFRS ratios are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These ratios are not standardized financial measures under IFRS, and therefore may not be comparable to similar financial measures disclosed by other issuers. Certain additional disclosures for these non-IFRS ratios are incorporated by reference and can be found in "Section 10: Non-IFRS and Other Financial Measures" in the Company's management's discussion and analysis for the three and nine months ended September 30, 2023, available on SEDAR+ at www.sedarplus.com.

Cash Cost

The objective of Cash Cost is to provide stakeholders with a key indicator that reflects as close as possible the direct cost of producing and selling an ounce of gold. The Company reports Cash Cost per ounce of gold sold which is calculated by deducting revenue from silver sales and depreciation and amortization from costs of sales, and dividing the difference by the number of gold ounces sold. Production Cash Cost includes mining, milling, mine site security, royalties, and mine site administration costs, and exclude non-cash operating expenses. Cash Cost per ounce of gold sold is a non-IFRS financial measure used to monitor the performance of our gold mining operations and their ability to generate profit, and is consistent with the guidance methodology set out by the World Gold Council.

All-In Sustaining Cost ("AISC")

The objective of AISC is to provide stakeholders with a key indicator that reflects as close as possible the full cost of producing and selling an ounce of gold. AISC per ounce of gold sold is a non-IFRS ratio that is intended to provide investors with transparency regarding the total costs of producing one ounce of gold in the relevant period. The Company reports AISC per ounce of gold sold on a by-product basis. The methodology for calculating AISC per ounce of gold sold is set out below and is consistent with the guidance methodology set out by the World Gold Council. The World Gold Council definition of AISC seeks to extend the definition of total Cash Cost by deducting administrative expenses, cost of sales of non-mining operations, sustaining exploration, sustaining leases and leaseback and sustaining capital expenditures. Non-sustaining costs are primarily those related to new operations and major projects at existing operations that are expected to materially benefit the current operation. The determination of classification of sustaining versus non-sustaining requires judgment by management. AISC excludes current and deferred income tax payments, finance expenses and other expenses. Consequently, these measures are not representative of all of the Company's cash expenditures. In addition, the calculation of AISC does not include depreciation and amortization cost or expense as it does not reflect the impact of expenditures incurred in prior periods. Therefore, it is not indicative of the Company's overall profitability. Other companies may quantify these measures differently because of different underlying principles and policies applied. Differences may also occur due to different definitions of sustaining versus non-sustaining.
