Magnetite Mines Ltd says it has appointed Hatch to complete the process plant section of the Definitive Feasibility Study (DFS) on its Razorback iron ore project in South Australia.
This, Magnetite Mines says, is an important contract award for the company and represents the largest component of the DFS expenditure and completes the appointment of major engineering roles.
Hatch’s scope builds upon the process plant design and AACE Class 4 Estimate that was completed as part of the prefeasibility study (PFS). This study supported the declaration of a maiden ore reserve of 473 Mt based on 12.8 Mt/y plant throughput and 2 Mt/y of high-grade concentrate. It also included plans to incorporate ore sorting technology.
Key areas of work for Hatch on the DFS include:
- Designing a metallurgical test program to confirm comminution and processing properties;
- Improving and defining the process flow sheet based on metallurgical results and optimisation reviews;
- Developing the mechanical, piping, electrical, structural, and civil engineering to support an AACE Class 3 Capital Cost estimate; and
- Providing construction and procurement input to develop the contracting strategy for execution.
At completion of this scope of work, Hatch will provide design deliverables and cost estimate, developed in line with the AACE guidelines for a Class 3 estimate (18R-97) for the process plant, Magnetite Mines says. The deliverables will be to a standard and level of detail that will allow Magnetite Mines to include them in a tender package to obtain proposals for a predominantly fixed price design and construct contract or an engineering, procurement and construction management contract on market terms for procurement of the process plant.
Claude D’Cruz, Director – Metals, Australia-Asia for Hatch, said: “Following the successful delivery of the previous study work, Hatch is very excited to continue our association with Magnetite Mines through to the DFS and to be able to apply our considerable magnetite processing experience to the development of Razorback.”
Magnetite Mines Limited Executive Chairman, Peter Schubert, said: “The PFS confirmed the process plant scope and the attractiveness of producing high-grade iron ore products at a competitive cost from the first stage of development of the company’s extensive iron ore resources. The DFS will undertake more detailed engineering and generate the tender packages for construction, supporting a decision to mine.
“This continues our strategy to carefully and systematically progress the project with the guidance of best-in-class technical consultants. We look forward to working with Hatch, as we develop Razorback into a successful operating iron ore business.”
