CORPORATE HIGHLIGHTS FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2023

Disposition of Minas Argentinas S.A. ("MASA")

On September 8, 2023, Mineros announced that it had signed a share purchase and sale agreement with Eris LLC dated September 7, 2023 to sell all of the outstanding shares of Mineros' subsidiary, Minas Argentinas S.A. ("MASA"). MASA holds a 100% interest in the Gualcamayo Property, which includes the Gualcamayo Mine and the Deep Carbonates Project. The transaction was completed on September 21, 2023.

Temporary suspension of the main processing plant at the Hemco Property in Nicaragua

On July 31, 2023, Mineros suspended operations at the Hemco Plant, its main processing plant at the Hemco Property, for two weeks. The Hemco Plant processes 89% of the material and disposal of tailings at the Hemco Property. The suspension was precautionary in nature, to allow for the swift completion of tailings detoxification capacity enhancements at the San José Tailings Dam, the primary tailings processing facility at the Hemco Property, prior to hurricane season in Nicaragua.

NON-IFRS AND OTHER FINANCIAL MEASURES

The Company has included certain non-IFRS financial measures and non-IFRS ratios in this MD&A. 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, and Adjusted EBITDA to net profit for the three and nine months ended September 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 nine months ended September 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 nine months ended September 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 and nine months ended September 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 September 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 September 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 and nine months ended September 30, 2023 and 2022:
