Monitor for Q3 production update and any extension of repair timeline. The 3-week outage at Guanacevi will reduce quarterly output, but the impact is temporary and parts are on hand. Watch for any indication of further mechanical issues at other mills.

Executive Summary
Endeavour Silver reported a mechanical issue at its Guanacevi mine, taking the primary ball mill offline on September 21. Repairs are expected to take ~3 weeks, during which throughput will drop to ~600 tpd from ~1,100 tpd. Mining continues uninterrupted and replacement parts are already on site, but the ~45% capacity reduction will negatively impact Q3 production.
Key Facts
- Primary ball mill at Guanacevi mine taken offline September 21 due to mechanical issue
- Repairs expected to take approximately three weeks
- Throughput reduced to ~600 tonnes per day vs. normal ~1,100 tpd (45% reduction)
- Replacement parts (mill head and trunnion) already on site; repair cost expected to be minimal
- Mining operations continue uninterrupted
Financial Impact
~45% reduction in mill throughput for ~3 weeks will materially reduce Q3 production from Guanacevi, one of three operating mines. No dollar estimate provided in filing.
Risk Factors
- Repairs may take longer than three weeks, extending production disruption
- Reduced throughput could lead to higher unit costs and lower margins in Q3
- Mechanical issue may signal broader maintenance or operational risks at Guanacevi
