Cleaning up the Margajita River
When we took operational control of our Pueblo Viejo mine in 2012, the local Margajita River was commonly known by locals as the Coca-Cola river due to its dark colour — a result of acid rock drainage from the mine.
Since then we have worked diligently to restore the river in the Dominican Republic by investing in a state-of-the-art onsite water treatment plant, and making sure all water discharged from the mine meets international standards.
As a result of these efforts, the river has returned to its natural state, and many fish species have returned after an absence of many years.
