Financial and Operating Highlights.

Operational Highlights by Material Property.

(All numbers in ounces unless otherwise noted)

For the three months ended June 30, 2023, gold production was down 6%, with 69,254 ounces of gold produced, compared to 74,062 ounces in the second quarter of 2022, summarized in the table above. The decrease in production relative to the comparative quarter in 2022 is a result of lower production achieved at the Hemco Property due to unscheduled maintenance stoppages at the milling area and lower production at the Gualcamayo Mine as it nears the end of its life of mine.

For the six months ended June 30, 2023, gold production was down 8%, with 129,502 ounces of gold were produced during the six months ended June 30, 2023, compared to 140,071 ounces in the same period of 2022. The lower production relative to the comparative period in 2022 is as a result of lower production from the underground mine at the Hemco Property due to unscheduled maintenance stoppages at the milling area during the second quarter and a decrease in production at the Gualcamayo Mine.

CORPORATE HIGHLIGHTS FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2023

New collective agreement in Colombia

On June 8, 2023, Mineros signed a collective agreement for operations at the Nechí Alluvial Property in Colombia, covering a two year period, starting May 1, 2023.

Termination of strategic alliance with Royal Road Minerals Ltd.

Effective May 29, 2023, Mineros terminated and, where applicable, settled all outstanding obligations under all of its agreements with Royal Road Minerals Ltd. ("Royal Road").

Mineros and Royal Road have terminated their strategic alliance agreements for exploration of their respective properties in Nicaragua and Colombia, and related joint ventures in respect of the Caribe Exploration Target, located on the Hemco Property in Nicaragua, and the Guintar-Niverengo-Margaritas ("GNM") Exploration Target, located in the Anzá Province, Colombia.

Royal Road has relinquished its 50% joint venture interest in the Caribe Exploration Target to Mineros' subsidiary Hemco Nicaragua S.A. ("Hemco"), which now owns 100% of the Caribe Exploration Target. The 1.25% net smelter returns royalty applicable to the two concessions that host the Luna Roja Deposit, which was granted to Royal Road in May 2021 in connection with Mineros' acquisition of Royal Road's 50% joint venture interest in those concessions, was terminated, and provisions under the related asset purchase agreement in respect of exploration expenditures to be incurred at the Hemco Property have been released. Mineros has also relinquished its 50% joint venture interest in the GNM Exploration Target to Royal Road. Mineros and Royal Road have also annulled a cooperation agreement relating to Mineros' Gualcamayo Project in Argentina.

Subsequent events

Temporary suspension of the main processing plant at the Hemco Property in Nicaragua and Review of 2023 Guidance

On July 31, 2023, Mineros determined to temporarily suspend operations at its main processing plant, which processes 89% of the material and disposal of tailings at its Hemco Property in Nicaragua. The suspension is precautionary in nature and is designed to allow for the swift completion of the expansion of its detoxification capacity at the tailings facility prior to hurricane season in Nicaragua. This work had been planned for earlier in 2023 but had been delayed by post-pandemic equipment supply constraints. Given the shutdown, the Company has taken this opportunity to perform certain plant maintenance work which was originally scheduled for later this year. During the suspension period, which is estimated to last for approximately 20 days, industrial and artisanal mining activities will continue and the Vesmisa and La Curva plants will also continue to operate. This precautionary suspension is expected to reduce the Hemco Property's output by approximately 5,000 to 10,000 ounces of gold for the month of August. Mineros is currently reviewing its mining plan for the Hemco Property for the second half of 2023 with a view to minimizing the impact, if any, on our production guidance for 2023.

In light of the recent temporary suspension of operations at the main facility at the Hemco Property, the Company's 2023 guidance is currently under review. Mineros will keep the market informed of further developments.

GROWTH AND EXPLORATION PROJECT UPDATES

Porvenir Project, Nicaragua: A total of 4,957 metres of diamond drilling in 36 holes was completed in the second quarter of 2023, achieving 85% of the program, with the objective of providing material for metallurgical test work. The metallurgical drilling campaign is expected to be completed by the third quarter of 2023.

Luna Roja Deposit, Nicaragua: In the second quarter of 2023, the Company has been working to update the geological model for the Luna Roja Deposit and is continuing to interpret the results of its 2022 drilling campaign.

NON-IFRS AND OTHER FINANCIAL MEASURES

The Company has included certain Non-IFRS financial measures and Non-IFRS ratios in this news release. 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 the Adjusted EBITDA for the three and six months ended June 30, 2023 and 2022:

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 Cost 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 excludes 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 six months ended June 30, 2023 and 2022:

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, 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.

The following table provides a reconciliation of AISC per ounce of gold sold to cost of sales for the three and six months ended June 30, 2023 and 2022:

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 sets out the calculation of the Company's net free cash flow to net cash flows generated by operating activities for the three months ended June 30, 2023 and 2022:

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 table sets out the calculation of ROCE as at June 30, 2023 and 2022.

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 June 30, 2023 and 2022.

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 table sets out the reconciliation of average realized metal prices to sales of gold and sales of silver for the three months ended June 30, 2023 and 2022:
