Strandline Resources has announced that it has taken another key step towards development of its Coburn mineral sands project in Western Australia by selecting Macmahon Holdings as the preferred contractor to provide mining services for the project. The parties have signed an early contractor involvement agreement ECI Agreement for early works associated with contract mining services.
Under the ECI Agreement the parties will work exclusively over the coming months to further optimise the mining solution and conclude contract documentation. The scope of the mining services contract will include mining of ore at a rate of 23.4 Mty overburden removal pit backfill and land recontouring transfer of concentrate from the Wet Concentrator Plant WCP to the Mineral Separation Plant MSP and general mining-related earthworks.
The contract mining term is expected to cover the first five years of Coburns production. Coburn is a world-class long-life mineral sands deposit hosting exceptional zircon and titanium mineral sands products. The mining method is conventional open pit dry mining in free-dig sand with in-pit tailings deposition progressive backfill and rehabilitation.
8220Macmahons experience in large bulk materials handling and mining including dozer push operations means it is well credentialled to meet Coburns mining requirements. Macmahons solution provides Strandline with a long-term safe reliable and highly efficient mining solution for Coburn. The financial terms of the mining contract will utilise an alliancing-style commercial framework based onthe mine plan methodologies and productivity estimate assumptions contained in the Coburn Definitive Feasibility Study DFS released Apr-2019.8221
The Coburn DFS shows the project will generate strong financial returns with a pre-tax NPV of A551 million an IRR of 32 Life of Mine EBITDA of A1.9 billion over the initial 22.5 years average annual EBITDA of A86 million and an attractive revenue-to-operating cost ratio of 2.2 based on TZMIs commodity price forecast. Strandline Managing Director Luke Graham said the agreement with a highly reputable mining contractor in Macmahon forms a key part of Strandlinesstrategy to prepare for near-term development.
