Strandline Resources has achieved a significant upgrade at the Coburn mineral sands project in Western Australia following the completion of its definitive feasibility study (DFS).
Coburn’s JORC-compliant ore reserve now stands at 523 million tonnes at an average grade of 1.11 per cent total heavy minerals (THM) for 5.8 million tonnes of contained THM.
The total mineral resource, which was determined in November last year, stands at 1.6 billion tonnes with an average yield of 1.2 per cent THM.
This upgrade represents a 70 per cent increase to Coburn’s previous ore reserve of 308 million tonnes at an average of 1.2 per cent THM from 2008.
The Coburn mine has a planned life of 22.5 years at an average production rate of 23.4 million tonnes a year, with the capacity to supply THM concentrate and final product through the addition of a mineral separation plant.
Strandline managing director Luke Graham said Coburn’s location in a Tier 1 mining jurisdiction and proximity to “key infrastructure” further enhanced the project’s status.
“This is a superb result which establishes Coburn as a major mineral sands project with large scale, long mine life and ample scope for further growth,” he said.
“The detailed mining study also confirms that Coburn boasts a valuable zircon-titanium mineral sands reserve, conventional open pit dry mining and a cost-efficient and practical operating plan.”
