Endeavour Silver reported substantial revenue growth in Q2 2025, bolstered by higher precious metal prices and the integration of the new Kolpa mine, but faced ongoing operational challenges as it approaches commercial production at Terronera.

• Production reached 2.5 million silver equivalent ounces, a 13% increase year-over-year, driven by the new Kolpa mine's contribution.
• Revenue surged by 46% to $85 million, benefiting from improved precious metal prices and production levels.
• The company incurred a net loss of $20 million due to commissioning losses at Terronera and increased general and administrative costs related to the Kolpa acquisition.
• Cash costs were maintained below guidance at $15.35 per ounce for payable silver, with all-in sustaining costs recorded at $25 per ounce.
• Endeavour is on track for a future annual production profile of 20 million silver equivalent ounces, supported by ongoing ramp-up efforts at Terronera and improvements at Kolpa.
