Muzariri said the company had previously been in "limbo" because land restitution and claims had arrested active mining.
The company had transferred mining rights to the Richtersveld community - its largest area of operations - and set up a joint venture to be run by an independent board and management.
Alexkor would retain a 51% holding though as necessary skills and resources would still be needed.
"The Richtersveld Mining Company does not have the business acumen... Someone needs to partner with the community," Muzariri said.
Alexkor would also expand its mining operations to the broader South African regions, and look at possibilities in Angola, the Democratic Republic of Congo and Zimbabwe.
