Actively managing the impact on our communities and the environment

Our Approach to the Environment

One of our main responsibilities as a company is to minimize our impact on the environment and on our host communities. An operating mine has environmental impacts and all of our stakeholders expect a high standard of performance from Teranga.

We take a proactive approach throughout the life of mine to address any temporary or long-lasting effects that our operations may have on the environment. We first assess potential impacts and then evaluate how to avoid or mitigate them.  Our aim is to preserve the long-term function and viability of the natural environments affected by our presence in Senegal, Burkina Faso, and as we move into Côte d’Ivoire.
