Endeavour Silver Reports Temporary Reduced Capacity at its Guanacevi Mine
VANCOUVER, British Columbia, Sept. 22, 2026 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (“Endeavour” or the “Company”) (NYSE: EXK; TSX: EDR) has identified a mechanical issue affecting the primary ball mill at its Guanacevi Mine.
The mill has been taken offline as of September 21, while preparations are completed to replace the mill head and trunnion, both of which are available on site. The Company expects the repairs to be completed within approximately three weeks and is coordinating with third-party service providers to expedite the replacement.
During the repair period, the regrind circuit will be configured to operate at a reduced throughput of 600 tonnes per day (tpd), compared to ordinary course capacity of approximately 1,100 tpd.
Mining operations will continue uninterrupted. The cost of replacing the affected components is expected to be minimal, as the necessary parts are already in inventory on site.
About Endeavour Silver – Endeavour is a mid-tier silver producer with three operating mines in Mexico and Peru and a robust pipeline of exploration projects across Mexico, Chile, and the United States. With a proven track record of discovery, development, and responsible mining, Endeavour is driving organic growth and creating lasting value on its path to becoming a leading senior silver producer.
