For­tuna Sil­ver’s San Jose con­tin­gency pond over­flows

For­tuna Sil­ver Mines Inc.’s con­tin­gency pond at its San Jose mine’s dry stack tail­ings fa­cil­ity has over­flowed as a re­sult of ab­nor­mally high rain­fall. The com­pany says no in­dus­trial process wa­ter was dis­charged in this in­ci­dent.

IN THE early morn­ing of Oct. 8, 2018, 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 rain­wa­ter. 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 me­tres, and it is equipped with a 600-cu­bic-me­tre-per-hour pump­ing ca­pac­ity, which was sur­passed by the vol­ume of rain­fall. The over­flow oc­curred for about two hours at ap­prox­i­mately 4 a.m. and re­sulted in the spill of ap­prox­i­mately 1,500 cu­bic me­tres 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.

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 the com­pany’s fa­cil­i­ties at San Jose and the Coy­ote Creek.
