For the three months ended March 31, 2024, revenue, net of $0.5 million of smelting and refining costs, increased by 15% to $63.7 million (Q1 2023: $55.5 million).

Gross sales of $64.2 million in Q1 2024 represented a 14% increase over the $56.1 million in Q1 2023. Silver oz sold increased by 5%, driven by a net decrease in finished goods silver ounces available for sale as at March 31, 2024, compared to December 31, 2023, offset by lower silver production. There was a 1% increase in the realized silver price, together with the higher silver oz sold resulting in an 7% increase in gross silver revenue. Gold oz sold increased by 19% with a 10% increase in the realized gold price, resulting in a 31% increase in gross gold revenue. During the period, the Company sold 1,756,094 oz silver and 10,880 oz gold for average realized prices of $23.47 and $2,114 per oz, respectively, compared to Q1 2023 sales of 1,667,408 oz silver and 9,126 oz gold for average realized prices of $23.16 and $1,917 per oz, respectively. In Q1 2024, London spot prices for silver and gold averaged $23.36 and $2,072, respectively.

After cost of sales of $52.1 million (Q1 2023 - $39.5 million), an increase of 32%, mine operating earnings were $11.7 million (Q1 2023 - $16.0 million). The cost of sales in Q1 2024 was impacted by higher labour, power and consumables costs as the Company continued to experience inflationary pressures. . Additionally direct costs were impacted by lower grades in Guanaceví compared to Q1 2023, and higher depreciation costs.

The Company had operating earnings of $3.3 million (Q1 2023: $6.9 million) after exploration and evaluation costs of $4.3 million (Q1 2023: $4.2 million) and general and administrative costs of $4.0 million (Q1 2023: $4.9 million). Exploration and evaluation costs were consistent with the same period in 2023, and related primarily to costs for Terronera that are not eligible for capitalization as a cost of building the project, such as social, environmental and management oversight. Exploration costs were also incurred at the Pitarrilla project and, to a lesser extent, brownfields exploration at Bolanitos and desktop evaluation work at Guanacevi. General and administrative costs decreased primarily due to investment in a new ERP system during 2023.

Earnings before income taxes were $4.2 million (Q1 2023: $12.5 million) after finance costs of $0.3 million (Q1 2023: $0.4 million), a foreign exchange gain of $1.2 million (Q1 2023: $1.9 million), and investment and other income of $0.0 million (Q1 2023: $4.0 million). The decrease in earnings before income taxes was driven by the unrealized gain on marketable securities and warrants of $3.1 million recorded in the 2023 comparative period compared to $0.9 million unrealized gain in Q1 2024.

The Company realized net loss for the period of $1.2 million (Q1 2023: net earnings $6.5 million) after an income tax expense of $5.4 million (Q1 2023: $6.1 million). Current income tax expense increased to $5.6 million (Q1 2023 - $4.4 million) and deferred income tax recovery of $0.2 million (Q1 2023: deferred tax expense of $1.7 million). Taxable profits are incurred at Guanacevi and changes in deferred income taxes are derived from changes in temporary timing differences between deductions for accounting versus deductions for tax.

Direct operating costs⁽²⁾ on a per tonne basis increased to $145.75, up 10% compared with Q1 2023 due to higher operating costs at Guanaceví from ongoing ventilation and water management challenges affecting productivity, as well as ongoing inflationary pressure on costs.

Consolidated cash costs per oz, net of by-product credits, increased to $13.19 primarily due to the higher direct costs per tonne, lower grade achieved at Guanaceví offset by a higher gold credit driven by higher gold production and gold sale price compared to Q1 2023. AISC increased by 6% on a per oz basis compared to Q1 2023 as a result of costs being allocated over fewer ounces produced, offset in part by lower sustaining capex.
