NON-IFRS MEASURES

The Company has included certain non-IFRS financial measures and ratios in this news release, as discussed below. The Company believes that these measures, in addition to measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company. The non-IFRS measures and 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 financial measures and ratios do not have any standardized meaning prescribed under IFRS and therefore may not be comparable to other issuers.

EBITDA and Adjusted EBITDA

“EBITDA” is comprised as income (loss) less interest, income tax and depreciation and amortization. Management believes that EBITDA is a useful indicator for investors, and is used by management, in evaluating the operating performance of the Company. See “Reconciliation of Net (Loss) / Income to Adjusted EBITDA” for a quantitative reconciliation of EBITDA to the most directly comparable financial measure.

“Adjusted EBITDA” is comprised as income (loss) less interest, income tax, depreciation, amortization, share-based compensation, foreign exchange gain (loss), and certain non-recurring or non-cash items where applicable. Management believes that Adjusted EBITDA is a useful indicator for investors, and is used by management, in evaluating the operating performance of the Company.

Cash Costs and All-In Sustaining Cost (“AISC”)

The Company uses cash costs, cash costs per AgEq ounce produced, AISC, and AISC per AgEq ounce produced to manage and evaluate its operating performance in addition to IFRS measures because the Company believes that conventional measures of performance prepared in accordance with IFRS do not fully illustrate the ability of its operations to generate cash flows. Management and certain investors also use this information to evaluate the Company’s performance relative to peers who present this measure on a similar basis.

Cash costs are calculated by starting with cost of sales, and then adding treatment and refining charges, and changes in depreciation and amortization. Cash costs per AgEq ounce is calculated by dividing cash costs by the AgEq ounces produced. AISC and AISC per AgEq ounce produced are calculated based on guidance published by the World Gold Council and used as a standard of the Silver Institute. AISC is calculated by taking the cash costs and adding sustaining costs. Sustaining costs are defined as capital expenditures and other expenditures that are necessary to maintain current production. Management has exercised judgment in making this determination.

Cautionary Note Regarding Production without Mineral Reserves

The decision to commence production at the Nueva Recuperada Project and the Company’s ongoing mining operations as referenced herein (the “Production Decision and Operations”) are based on economic models prepared by the Company in conjunction with management’s knowledge of the property and the existing estimate of mineral resources on the property. The Production Decision and Operations are not based on a pre-feasibility study or a feasibility study of mineral reserves demonstrating economic and technical viability. The 2025 Preliminary Economic Assessment referred to in this news release is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that its results will be realized. Accordingly, there is increased uncertainty and economic and technical risks of failure associated with the Production Decision and Operations, in particular: the risk that mineral grades will be lower than expected; the risk that additional construction or ongoing mining operations are more difficult or more expensive than expected; and production and economic variables may vary considerably.
