(“Endeavour” or the “Company”) (NYSE: EXK; TSX: EDR) reports second quarter 2025 production of 1,483,736 silver ounces (oz), 7,755 gold oz, and in combination with base metal production a silver equivalent⁽¹⁾ (“AgEq”) total production of 2.5 million oz. All dollar amounts are in US dollars ($).

At the same time, Terronera continues to move steadily toward commercial production. This is a pivotal time for Endeavour as we build operational momentum and position the Company for meaningful, long-term growth."

Q2 2025 Production Overview

• Guanaceví Maintains Consistent Production: Production in line with plan, with gold production slightly above plan and silver production at the lower end of the planned range.
   
• Bolañitos Continues to Perform: Due to the lower throughput in May and June, silver and gold production were both slightly below plan.
   
• Kolpa Delivers Strong Results at a Stable Rate: Throughput and production of metals were in line with historical results and management’s expectations.
   
• Terronera Ramp-Up Phase Advances Toward Commercial Production: Daily production averaged 1,400 tonnes per day (tpd) in the second half of June.
   
• Metal Sales and Inventories: Sold 1,477,197 silver ounces and 7,706 gold ounces during the second quarter. A total of 242,980 silver ounces and 701 gold ounces of bullion inventory and 24,970 silver ounces and 399 gold ounces in concentrate inventory were held at June 30, 2025.

Q2 2025 Mine Operations

Consolidated silver production was 1,483,736 ounces in Q2 2025, in line with plan and 13% higher than Q1 2024 due to the addition of Kolpa operation into the portfolio. Excluding production from Kolpa, consolidated production was 16% lower than Q2 2024, slightly below  plan, due to the 17% lower production in Guanaceví mine and 10% lower production in Bolañitos mine. Consolidated gold production was 7,755 ounces in Q2 2025, 26% lower than Q2 2024. Lower gold production was due to 34% lower production at the Bolañitos mine, and 16% lower gold production at the Guanaceví mine.

In Q2 2025, Guanaceví throughput was 14% lower than Q2 2024 and silver and gold grades were 1% lower, which drove the 17% lower silver and 16% lower gold output. Guanaceví throughput and grades were in line with plan. Supplies of local third-party feed continued to supplement mine production, amounting to 21% of quarterly throughput.
                                         
Bolañitos Q2 2025 throughput was 17% lower than throughput in Q2 2024, combined with 10% higher silver grades offset by 19% lower gold grades. Silver production was 10% lower than in the same period in 2024, while gold production was 34% lower. Throughput was below the plan, while silver and silver grades were consistent with plan. The grade variation is due to mining from different locations in the ore body.

Since the acquisition of Kolpa on May 1, Kolpa processed 118,896 tonnes of material grading 111 grams of silver per tonne and, 3.13% lead, 2.25% zinc and 0.22% copper. These results are in line with management’s expectations established at the time of acquisition and reflect the ongoing efficiency of current mining and processing activities. The Company is actively advancing integration to ensure a smooth alignment of systems, teams, and operational processes. The team remains focused on maintaining steady output and advancing Kolpa’s contribution to the Company’s long-term growth strategy.

Terronera Update

The commissioning and ramp-up of Terronera continues to progress steadily, with plant throughput gradually increasing as operational bottlenecks and system issues are identified and resolved. In June, throughput averaged 1,232 tonnes per day (tpd), with a peak single-day throughput of 1,987 tpd. Notably, throughput stabilized in the second half of the month, with daily production averaging 1,400 tpd.

After successfully processing lower-grade material to address bottlenecks and system issues, the plant has now shifted its focus to refining operations, including processing higher grade ore to achieve planned metal recoveries. Management expects to gradually ramp up throughput to design capacity in early Q3.

During commissioning of the plant, the underground mine has continued with mine development and stope preparation. Surface stockpiles are limited and at capacity at this time.

As of the end of June, Terronera had produced and sold a cumulative 598 tonnes of concentrate, generating approximately $3 million in revenue.
