The approval has been granted via a licence amendment to the Department of Water and Environmental Regulation’s (DWER) Environment Licence L7922/1989/5.
DWER and the Department of Mines, Industry Regulation and Safety (DMIRS) have assisted Artemis with approvals for the construction and operation permits at Radio Hill.
Representatives from both departments have carried out multiple inspections at the Radio Hill site, which is 30 kilometres from Karratha.
Artemis’ non-executive chairman Sheik Maktoum said: “Approval for the use of TSF3 at Radio Hill is a major milestone, which brings Artemis closer to having the Radio Hill plant back into an operational state.”
Clearing permit granted
In addition, Artemis has secured a Native Vegetation Clearing Permit (NVCP) for clearing 64.52 hectares at Radio Hill.
This will provide a future footprint for long-term tailings storage in TSF4 and for access to clay material to cap and close existing TSF 1 and 2.
TSF4 will be a larger standalone 4 million tonnes tailing storage facility.
Sheaik Maktoum said: “Land clearing for a future tailings storage facility is approved and background work will continue on this as we focus attention on Carlow Castle metallurgy and start to revisit the gold at 47 K Patch.”
After receiving these approvals and completion of a geotechnical and engineering study, the company will work towards seeking approval for TSF4.
Gold circuit 80% complete
Radio Hill’s gravity gold circuit is around 80% complete.
A decision on beginning operations is contingent upon at least three-years of an economic ore source, or successful negotiations on toll-treating options.
The company continues to advance the Carlow Castle Gold-Copper-Cobalt Project, which is one of the projects that could feed the Radio Hill operations and processing infrastructure.
A further round of metallurgy towards scoping study and feasibility is contingent on further metallurgical sampling.
For this purpose, Artemis is considering the best way to obtain relevant samples, which may be by large diameter diamond drilling or by excavator and pitting, due to the shallow nature of the ore body.
