ON MEXICO ISSUES
- Fortuna Silver Mines Inc., announced that it is trying to avoid the closure of its San Jose silver mine in Oaxaca after the expiration of its environmental permit last month. Although the San Jose mine has been in operation since 2011, its main environmental authorization expired on October 23, despite the company’s efforts since May to request an extension of the permit. A recent court order allows the mine to continue operating, but only temporarily. Maria Luisa Albores, the Environment Secretariat issued a statement saying it would work to organize a consultation with indigenous communities close to the project as part of the environmental authorization. It did not provide details on the timing of the consultation, nor did it say whether the mine could continue to operate in the meantime. The company stated that it is fighting for the stability of 1,200 active workers of its San Jose mine.
- Mexico’s Secretary of the Environment and Natural Resources (SEMARNAT) announced that it will carry out an indigenous consultation to define the future of the San Jose mine in Oaxaca. A dozen of Zapotecas communities will decide whether the San José mine, owned by Minera Cuzcatlán, will continue operating in the Valles Centrales region of Oaxaca, through a consultation carried out by the Ministry of SEMARNAT. It should be noted that the San José mine has four environmental impact authorizations in force, however there is another one that expired on October 23, and although the company requested its extension in due time and form, SEMARNAT has not issued a ruling.
- Fortuna Silver Mines Inc., provided an update on the appeal to the denial of the extension of the environmental impact authorization (EIA) at its San Jose mine, Oaxaca. “The appeal will be brought by Minera Cuzcatlán in the Mexican court. The grounds for the appeal are that Minera Cuzcatlán is in full compliance with all material environmental laws, and therefore Minera Cuzcatlán has the right to an extension of the EIA under applicable law”.
