Soil Conservation in Milache, Guanaceví


Soil plays a fundamental role in all ecosystems, providing functions such as capturing CO2 emissions, regulating humidity, contributing to recharging aquifers and more. Soil is considered a non-renewable natural resource because it is difficult and expensive to repair or improve its properties if it has been physically or chemically damaged.

Mining and stockpiling activities, if not managed responsibly, can have adverse impacts on soil. We believe that development and conservation can coexist in harmony, which is why we make every effort to reduce and mitigate any possible impacts to soil touched by our operations. This is especially important as we start new projects when land is first disturbed.

Our commitment to soil conservation and protection was reflected most recently in the steps we took at our new project, Milache in the Guanaceví mine. Our actions included:

  • Building retention dams – these permanent flexible structures allow water to continue with their normal flow but capture mining waste material (that if left to run off, can promote soil erosion).
  • Deploying dead plant material, recovered from the forest industry, over soil areas as a protective layer. This reduces the speed and the amount of surface running water and promotes natural vegetation regrowth.
  • Reforestation – we planted 3,510 pine trees to promote fertile soil, avoid erosion and purify the air, among other benefits.
