(1) Silver equivalent (AgEq) is calculated using an 80:1 Ag:Au ratio, 60:1 (Ag:Pb) ratio, 85:1 (Ag:Zn) ratio and 300:1 (Ag:Cu) ratio. (2) These are non-IFRS financial measures and ratios. Further details on these non-IFRS financial measures and ratios are provided at the end of this press release and in the MD&A accompanying the Company's financial statements, which can be viewed on the Company's website, on SEDAR+ at www.sedarplus.com and on EDGAR at www.sec.gov.

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.
