Acacia Mining North Mara Gold Mine (former Barrick Gold), Tanzania

The Mine opened in 2002, is owned by the UK public company Acacia Mining (formerly African Barrick Gold). Intead of bringing wealth for locals, the presence of the firm has provoked water contamination and human rights abuses


The North Mara Gold Mine opened in 2002 and is one of the three gold-producing mines in Tanzania owned by the UK public company Acacia Mining (formerly African Barrick Gold), the biggest gold producer in Tanzania listed on the Main Market of the London Stock Exchange.  The mine has produced over 2 million ounces of gold since 2002 and the current life of mine is estimated to be 9 years based on proven and probable gold reserves of 2 million ounces (4).
