The Ministry of Mines and Energy revoked three mineral exploration licences from two different Australian mining firms that failed to meet work performance guidelines, it said yesterday in a release.

According to the announcement, Summer Gold Investment’s single exploration licence and Riva Natural Resources’ two exploration licences were terminated at the end of June and the companies ordered to pay financial dues to the ministry.

The areas covered under the exploration licences included sites in Rattanakiri province, Mondulkiri province and an area that stretched between Banteay Meanchey province and Oddar Meanchey.
