Overview and locality
Mineração Serra Grande (Serra Grande or MSG) is wholly owned by AngloGold Ashanti and is located in the northwest of the state of Goiás, central Brazil.
The Serra Grande operation comprises three mechanised underground mines, namely Mina III, Mina Nova and Mina Palmeiras, and an open pit.
One dedicated metallurgical plant with an annual capacity of 1.5Mt treats all ore mined.
A brief history
- Exploration began in 1973 with detailed mapping and diamond drilling programme that continued until 1976
- The mining operation started up in 1986 in Mina III and the metallurgical plant start-up was in 1989.
- Annual production peaked at 193,000oz in 2006, supported by high grades.
- In 2009, the metallurgical plant was expanded to 1.3Mtpa to compensate for a declining grade-profile.
- In 2012, AngloGold Ashanti acquired the 50% stake that belonged to the Kinross Group.
- The suspension of waste deposition on the Calcinados TSF in the first quarter of 2023 necessitated a transition to gold-in-concentrate production and the subsequent loss of an estimated 5,000oz of annual production

This means that, at the end of ore processing, all the tailings generated go through a drying process after which it is placed in filtered tailings stacks. Wet tailings are no longer sent to the tailings storage facilities.
