Environmental Impact Assessment (EIA)

Geoservice Ingeniería

Preparation of Technical Report and Modification of Semi-Detailed Environmental Impact Assessment (EIASD).

The aim of Technical Report is to modify the location of complementary and auxiliary components, incorporate 45 new exploration drilling and opening a mine entrance without making enlargements of underground workings already approved .

Given the characteristics of the relocation of ancillary components as well as evaluating the environmental impacts of such changes, it is concluded that such modifications do not generate significant impacts.
