Mineros Reports Third Quarter 2022 Financial and Operational Results

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

MEDELLIN, Nov. 14, 2022 - Mineros S.A. (TSX: MSA) (CB: MINEROS) ("Mineros" or the "Company") today reported its financial and operational results for the three and nine months ended September 30, 2022. For further information please see the Company's condensed interim consolidated financial statements and management's discussion and analysis filed under Mineros' profile on www.sedar.com.

Andrés Restrepo, President and CEO of Mineros, commented, "The Company has had another strong quarter with respect to operational and financial results and remains on-track to achieve its annual guidance. Yet, net profits were affected by an impairment of assets related to the beneficiation plant that overturned on May 28 and severance provisions in Argentina. In the third quarter of 2022, Mineros produced 74,513 ounces of gold, a 17% increase from the same quarter in 2021. Along with increased production, the Company has seen reductions in both the all-in sustaining cost per ounce of gold sold and the cash cost per ounce of gold sold compared to the same period in 2021. The Company has a long track record and continues paying a strong quarterly dividend with a very attractive yield."

CORPORATE HIGHLIGHTS FOR THE THIRD QUARTER 2022

Luna Roja Deposit - initial Mineral Resource estimate

On July 7, 2022, the Company announced an initial Mineral Resource estimate for the Luna Roja Deposit, which included 1.164 million tonnes of indicated Mineral Resources averaging 2.46 grams of gold per tonne ("g/t Au"), for approximately 92,000 ounces of gold and 0.504 million tonnes of inferred mineral resources averaging 2.31 g/t Au, for approximately 37,000 ounces of gold. The initial Mineral Resource estimate assumes both open pit and underground mining and extends from surface to a depth of 200 metres. See the Company's July 7, 2022 press release entitled, "Mineros Announces Initial Mineral Resource Estimate for the Luna Roja Deposit, Nicaragua".

Overturning of Floating Beneficiation Plant at Nechi Alluvial Property

On May 28, 2022, a storm with unusually heavy rains and strong winds hit the area where the Nechí Alluvial Property is located and overturned the Llanuras Plant, a floating beneficiation plant connected to the Llanuras suction dredge. Immediately following the accident, the Company's emergency protocols were activated, which included a rescue operation followed by a coordinated search, and subsequent recovery actions. These operations are now complete and accident investigations by both the relevant Colombian authorities and independent investigators hired by the Company are underway.

After a thorough review, as of September 30, 2022, management had not found a way to recover, repair or perform any type of rescue or maneuver to refloat the Llanuras Plant, resulting in the recognition by the Company of a $4.8 million impairment of asset. Mineros has filed a claim with its insurers in respect of the damage to the Llanuras Plant. The Company has adjusted its production plan to compensate for the loss of the Llanuras Plant, and accordingly does not expect any negative impact on its ability to meet its 2022 production or cost guidance for the Nechí Alluvial Property.

Appointment of Vice President, Nicaragua

On July 11, 2022, Mineros announced the appointment of Mr. Luis Villa as Vice President, Nicaragua, effective as of October 1, 2022. Mr. Villa has been with the Company and its subsidiaries for 16 years, most recently in the position of Manager of Projects and Supply Chain for Mineros Alluvial S.A.S. BIC. Mr. Villa succeeds Mr. Carlos Mario Gomez, who retired effective September 30, 2022, following 14 years of service with the Company.

Appointment of Vice President, Business Development and Strategy

On August 26, 2022, Mineros announced the appointment of Ms. Ana María Ríos as Vice President, Business Development and Strategy, effective as of October 1, 2022. Ms. Ríos has seventeen years of professional experience, of which the last fourteen have been at Mineros, most recently as Corporate Finance Manager, where she played a strategic role in Mineros' listing on the Toronto Stock Exchange and initial public offering in Canada (the "Canadian IPO") and in the concurrent public offering in Colombia in November 2021 (the "Concurrent Colombian Public Offering"). Ms. Ríos succeeds Eduardo Flores Zelaya.

Workforce reduction in Argentina

On September 9, 2022, Mineros announced that over the next six months, it will downsize its operations at its Gualcamayo Property, reducing its workforce in Argentina by up to 30%, as a result of the natural depletion of the deposit. The Company expects to incur costs of between $3.0 million and $5.0 million in connection with the workforce reduction, but does not expect such costs to impact its ability to meet its previously-disclosed 2022 production and cost guidance for the Gualcamayo Property. As of September 30, 2022, a severance provision in the amount of $3.0 million was reported in connection with the downsizing of operations at the Gualcamayo Property.

Subsequent Events

OFAC Sanctions Imposed on General Directorate of Mines of Nicaragua

On October 24, 2022, the United States Department of the Treasury's Office of Foreign Assets Controls ("OFAC") imposed economic sanctions on General Directorate of Mines of Nicaragua ("DGM"), a subordinate office within the Nicaraguan Ministry of Energy and Mines, pursuant to Executive Order ("EO") 13851 of the U.S. President. As such, all properties and interests in property of the DGM are now blocked, and all transactions by U.S. persons or transiting the U.S. that involves blocked property are prohibited. All property or interest in property of any entity that is owned, directly or indirectly, 50% or more by the DGM are also blocked. Concurrently, OFAC issued General License No. 4, authorizing transactions ordinarily incident and necessary to wind down any transaction involving the DGM through November 23, 2022.

Also on October 24, 2022, the U.S. President also issued EO 14088 (together with EO 13851, the "Nicaragua Sanctions Measures"), which authorizes the U.S. government to promptly apply further sanctions to various sectors of the Nicaraguan economy such as the gold sector. Although EO 14088 specifically mentions the gold sector, as at the date of this document, no entity or person, other than the DGM and one official of the Government of Nicaragua, has been designated by OFAC under the Nicaragua Sanctions Measures.

The Company remains committed to complying with applicable legal and regulatory requirements, including sanctions, and is evaluating the actual and potential impacts of the U.S. sanctions on its current and planned business and operations in coordination with its advisors. As at the date of this document, U.S. sanctions measures adopted on October 24, 2022 have not resulted in any material impacts on its operations in Nicaragua, and the Company is continuing to evaluate their potential impact on its commercial relationships.

Election Not To Exercise Second Option at La Pepa Project

On October 25, 2022, the Company determined not to exercise its second option under the agreement executed on December 14, 2018, and effective as of July 2, 2019, between the Company, Yamana Gold Inc. ("Yamana"), and their respective affiliates (the "La Pepa Option Agreement") to earn an additional 31% interest in the La Pepa Project. As a result, the Company holds a 20% interest in the La Pepa Project and has ceased to be the operator of the project. Plans for further exploration of the La Pepa Project moving forward remain subject to discussion and have not been finalized at this time.

GROWTH PROJECT UPDATES

Porvenir Project, Nicaragua: Ongoing studies are being completed to assess processing and mining scenarios for the Porvenir Project. The Company is on track of complete a pre-feasibility study in the fourth quarter of 2022.

Luna Roja Deposit, Nicaragua: Mineral Resources for the Luna Roja Deposit are planned to be updated as at December 31, 2022. The 3,000-metre diamond drill campaign started in October and is planned to be completed by December 2022.

Gualcamayo Property Expansion, Argentina: In the third quarter of 2022 a total of 19,856 metres in 111 holes were drilled, 2,856 metres over the original drilling plan. The Company decided to cover broader areas of production with the same drilling budget by drilling more meters of Reverse Circulation, re-balancing its original drilling plan. The drilling campaign is progressing despite laboratory delays as a result of recent increased global demand for assay services.

Mineros reviewed its original greenfield exploration program on account of limited availability of drilling equipment in Argentina and there is no further drilling planned in this area in 2022.

Deep Carbonates Project, Argentina: Mineros reviewed its original 7,750 meter drilling plan as a consequence of general difficulties with deep drilling and limited availability of drilling equipment in the region. The Company plans to complete a total of 5,300 meters of diamond drilling focused on expanding the current mineral resources at the Rodado deposit. Metallurgical test work to support advancement of the Deep Carbonates Project is underway. The Company is still evaluating the test work to make a determination as to whether it will move forward with a preliminary economic assessment ("PEA") in respect of the Deep Carbonates Project.

La Pepa Project, Chile: The Company is focused on developing and expanding the Cavancha deposit and greenfield exploration is focused on new discoveries on the property with different styles of mineralization related to veins around the main Cavancha deposit.

NON-IFRS AND OTHER FINANCIAL MEASURES

The Company has included certain non-IFRS financial measures and non-IFRS ratios in this document. Management believes that non-IFRS financial measures and non-IFRS ratios, when supplementing measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-IFRS financial measures and non-IFRS ratios do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. This data is 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. For a discussion of the use of non-IFRS financial measures and reconciliations thereof to the most directly comparable IFRS measures, see below.

EBIT, EBITDA and Adjusted EBITDA

The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use the earnings before interest and tax ("EBIT"), earnings before interest, tax, depreciation and amortization ("EBITDA"), and adjusted earnings before interest, tax, depreciation and amortization ("Adjusted EBITDA"), which excludes certain non-operating income and expenses, such as financial income or expenses, hedging operations, exploration expenses, impairment of assets, foreign currency exchange differences, and other expenses (principally, donations, corporate projects and taxes incurred). The Company believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results because it is consistent with the indicators management uses internally to measure the Company's performance, and is an indicator of the performance of the Company's mining operations.

The following table provides a reconciliation of EBIT, EBITDA, Adjusted EBITDA to net profit for the period for the three and nine months ended September 30, 2022 and 2021:

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.

The following table provides a reconciliation of Cash Cost per ounce of gold sold on a by-product basis to cost of sales for the three and nine months ended September 30, 2022 and 2021:

All-in Sustaining Costs

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, 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.

The following table provides a reconciliation of AISC per ounce of gold sold to cost of sales for the three and nine months ended September 30, 2022 and 2021:

Net Free Cash Flow

The Company uses the financial measure "net free cash flow", which is a non-IFRS financial measure, to supplement information regarding cash flows generated by operating activities. The Company believes that in addition to IFRS financial measures, certain investors and analysts use this information to evaluate the Company's performance with respect to its operating cash flow capacity to meet recurring outflows of cash.

Net free cash flow is calculated as cash flows generated by operating activities less non-discretionary sustaining capital expenditures and interest and dividends paid related to the relevant period.

The following table provides a reconciliation of the Company's net free cash flow to net cash flows generated by operating activities for the three and nine months ended September 30, 2022 and 2021:

Return on Capital Employed

The Company uses ROCE as a measure of long-term operating performance to measure how effectively management utilizes the capital it has provided. This non-IFRS ratio is 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. The calculation of ROCE, expressed as a percentage, is Adjusted EBIT (calculated in the manner set out in the table below) divided by the average of the opening and closing capital employed for the 12 months preceding the period end. Capital employed for a period is calculated as total assets at the beginning of that period less total current liabilities. The following sets out the calculation of ROCE as at September 30, 2022 and 2021:

Net Debt to Adjusted EBITDA Ratio

Net Debt to Adjusted EBITDA ratio is a non?IFRS ratio that provides the liquidity position of the Company. The calculation of net debt shown below is calculated as nominal undiscounted debt including leases, less cash and cash equivalents. The following sets out the calculation of Net Debt to Adjusted EBITDA ratio as at September 30, 2022 and 2021:

Average Realized Price

The Company uses "average realized price per ounce of gold" and "average realized price per ounce of silver", which are non-IFRS financial measures. Average realized metal price represents the revenue from the sale of the underlying metal as per the statement of operations, adjusted to reflect the effect of trading at holding level (parent Company) on the sales of gold purchased from subsidiaries. Average realized prices are calculated as the revenue related to gold and silver sales divided by the number of ounces of metal sold. The following tables sets out the reconciliation of average realized metal prices to sales of gold and sales of silver for the three and nine months ended September 30, 2022 and 2021:
