On August 5, 2025 the Company announced that the throughput has rapidly increased with milling rates between 1,900 and 2,000 tpd at the end of July and that silver and gold recoveries have averaged 71% and 67%, respectively during second half of the July.

Financial Overview

Direct operating costs per tonne in Q2 2025 increased to $142.00, slightly higher than $140.36 in Q2 2024. This metric was impacted by: higher costs per tonne at Bolañitos with lower throughput as a result of maintenance of the floatation circuit and crushing area; the addition of Kolpa which has higher direct operating costs per tonne; offset by lower costs at Guanaceví.

Consolidated cash costs per oz, net of by-product credits, were 14% higher in Q2 2025 at $15.35 per oz, compared with Q2 2024, driven by an increase in costs at Bolañitos and Guanaceví from lower production, and partially offset by addition of Kolpa which at $11.81 per oz decreases the average cash cost. All-In-Sustaining Costs (“AISC”) in Q2 2025 was $25.16 per silver oz in Q2 2025, 9% higher compared to $23.13 per oz in Q2 2024, predominantly due to the addition of Kolpa which at $25.66 per oz increased the average AISC, and a slight increase of AISC at Guanaceví.

In Q2 2025, the Company’s mine operating earnings were $7.7 million (Q2 2024 – $10.2 million) from revenue of $85.3 million (Q2 2024 – $58.3 million) and cost of sales of $80.9 million (Q2 2024 – $48.1 million). The decrease in mine operating earnings is predominantly due to Terronera’s mine operating loss of $5.9 million as the mine ramped-up towards commercial production. The increase in the cost of sales compared to the prior period was driven by $21.5 million from Kolpa and $9.2 million increase from Terronera.

In Q2 2025, the Company had operating loss of $4.8 million (Q2 2024 – earnings of $1.7 million) after exploration, evaluation and development costs of $4.9 million (Q2 2024 – $4.3 million), and general and administrative expense of $7.6 million (Q2 2024 – $4.2 million). The increase in general and administrative expense is primarily due to the $3.6 million acquisition costs of Minera Kolpa.

The loss before taxes for Q2 2025 was $14.6 million (Q2 2024 – loss of $11.3 million) after loss on derivative contracts of $10.0 million (Q2 2024 – $9.2 million) and partially offset by a foreign exchange gain of $0.7 million (Q2 2024 – loss of $4.0 million), investment and other income of $0.7 million (Q2 2024 – $0.6 million), and finance costs of $1.1 million (Q2 2024 – $0.3 million).

The Company realized a net loss for the period of $20.5 million (Q2 2024 – net loss of $14.0 million) after an income tax expense of $5.9 million (Q2 2024 – $2.7 million). The deferred tax recovery was realized as a result of recognizing previously unutilized losses during the period.

Adjusted net loss was $9.2 million compared to adjusted net loss of $1.0 million in Q2 2024, largely due to the operating loss from Terronera during the commissioning phase and higher depreciation and tax costs.
