## Minestarters Atlas summary

Endeavour Silver reported strong Q1 2026 production, with consolidated silver output increasing 56% to 1,875,375 ounces and gold production rising 41% to 11,740 ounces year-over-year. This growth was primarily driven by contributions from the Terronera and Kolpa mines, despite some operational challenges at Guanacevi and Kolpa due to lower grades, throughput issues, and adverse weather. The company also commissioned new crushers and a ball mill at Kolpa, aiming to increase throughput to 2,500 tonnes per day in upcoming quarters.

Reasoning: The document reports strong Q1 2026 production results for Endeavour Silver, with significant increases in silver and gold output compared to Q1 2025, primarily due to contributions from Terronera and Kolpa. While some operational challenges and market conditions were noted, the overall production growth and operational improvements at key mines are positive signals for the company's performance.

- Positive factor: Significant increase in consolidated silver and gold production year-over-year, driven by new operations at Terronera and Kolpa.

- Positive factor: Strong silver equivalent production, indicating successful polymetallic operations.

- Positive factor: Improved grades and recoveries at Terronera, with processes being refined.

- Positive factor: Kolpa plant expansion commissioned, set to increase throughput in upcoming quarters.

- Negative factor: Silver production at Guanacevi was below plan due to lower grades and throughput.

- Negative factor: Kolpa's ramp-up was delayed by adverse weather and power outages, impacting throughput and metal production.

- Negative factor: Management decided to hold bullion inventory temporarily due to downward pressure on silver and gold prices.

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 30

## Classification and evidence

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Terronera's silver recovery averaged 84.0%, which is strong for a heap leach operation, and Guanacevi's silver recovery was 90.7%, which is strong for a mill route.

Evidence · text

> Terronera recoveries averaged 84.0% for silver and 72.7% for gold

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Kolpa's lead recovery was 94.3% and zinc recovery was 84.0%, both strong for a mill route.

Evidence · table

> 94.3%

Context: Lead recovery %

**Recovery Improving**

Polarity: positive

Definition: Recovery improved versus a like-for-like prior test program on the same domain and route.

Why it applies: Terronera's plant management refined processes to improve recoveries, which gradually improved throughout the period and are expected to further improve.

Evidence · text

> During the first quarter, plant management refined processes to improve recoveries which gradually improved throughout the period. In March, recoveries were in line with plan and are expected to further improve with additional optimization.

**Mill Route**

Polarity: neutral
