The standoff at a South African mine run by platinum producer Amplats has seen police clash with a crowd of men carrying traditional weapons such as spears and machetes.
A police spokesman said tear gas, stun grenades and rubber bullets were fired to disperse an "illegal gathering" at the mine outside the city of Rustenburg.
It remained unclear whether anyone was injured in the exchange.
The action was understood to have been inspired by the brokering of a new wage deal at a Lonmin mine in Marikana.
The standoff between striking miners and South African authorities hardened as workers rejected a new deal and 'gatherings' were banned.
