Showcasing our sustainable copper extraction initiatives.

A large open-pit mine with terraced levels carved into a hillside, creating a massive and layered appearance. The landscape is mostly barren with dusty roads leading to various levels of the pit. The scene is devoid of vegetation, emphasizing the stark industrial activity.

A scenic view of a historical mining site featuring a prominent red mining tower surrounded by various industrial buildings. The background presents a lush landscape with dense greenery and a town visible in the distance. A flag can be seen atop the tower, and a few people are gathered near the buildings, adding a touch of activity to the scene.
