Vice President Salvador Sanchez Ceren was emphatic in his statement that he will advocate for the suspension of all mining activity in the Trifinio Reserve area, alluding to the Cerro Blanco mining project located in Asuncion Mita, Guatemala , 18 kilometers away from Metapan.
A technical report carried out by Salvadoran authorities, after a visit to the mine, stated that the project has many shortcomings that could cause negative impacts on nearby bodies of water where toxic discharge will occur, contamination of the Ostúa river, could travel to the Güija lake and then to the Lempa river.
