Fortuna Silver Mines reports heavy seasonal rains caused an overflow in a contingency pond of the dry stack tailings facility at the San Jose Mine, Mexico
VANCOUVER, B.C., Oct. 11, 2018 (GLOBE NEWSWIRE) -- Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) reports that in the early morning of October 8th, abnormally high rainfall caused a contingency pond to overflow at the dry stack tailings facility at the San Jose mine located in Oaxaca, Mexico. The contingency pond collects water from a ditch system at the dry stack facility designed to capture and manage rain water. The Company wants to emphasize that no industrial process water was discharged in this incident and that the San Jose operation uses a cyanide-free process to produce concentrate.
The dry stack contingency pond’s holding capacity is 7,000 cubic meters and it is equipped with a 600 cubic meter per hour pumping capacity that was surpassed by the volume of rain fall. The overflow occurred for about two hours at approximately 4:00 am and resulted in the spill of approximately 1,500 cubic meters of water carrying sediment and minor amounts of fine tailings from the facility’s drainage system into the nearby Coyote Creek. The Company is mitigating the risk of future overflows by immediately increasing its pumping capacity at the contingency pond. No damage has occurred to the tailings dam or to the dry stack infrastructure and both are fully operational. San Jose tailings are monitored and sampled continuously, are free of heavy metals or other contaminants, and are characterized as sterile.
Officials at the Procuraduría Federal de Protección al Ambiente (PROFEPA) were notified of the overflow on the day of the incident. The Company is currently working with federal, state and local authorities as they conduct inspections of our facilities at San Jose and the Coyote Creek.
