Protesters from the Fatoyah community invaded the site on Friday, erected barricades and disrupted production in order to demand the tarring of a road. SAG had to suspend its operations to safeguard its staff and property, the company said.
"There is a tacit agreement between SAG and the villagers [...] to tar this road," resident Moussa Condé told Reuters by telephone.
AngloGold Ashanti spokesperson Stewart Bailey said the company is in talks with community leaders to resolve the dispute.
A 30 km (18.6 mile) tarred road linking the towns of Siguiri and Kintinian was recently completed, he said. The project was a partnership between the government and AngloGold Ashanti.
The suspension puts a halt to all extraction and processing activities at the mine and pauses sub-contracting services to SAG. Only a skeleton staff will remain on site, SAG said.
AngloGold Ashanti owns 85% of SAG, whose Siguiri mine produced 242,000 ounces (6.9 tonnes) of gold in 2018.
