Project Roper Bar Iron Ore Concept Study, Beneficiation Plant and Ore Handling, Phase I
The Roper Bar Iron Ore project is located in the new Roper Iron Ore Province in the Northern Territory. Drilling in the 2009 and 2010 field seasons has generated JORC-compliant Inferred Mineral Resource statements for a total of 311Mt @ 40% Fe including DSO (direct shipping ore) of 14.5Mt @ 57.4% Fe. Exploration and resource drilling is continuing.
The project owner, Western Desert Resources (WDR), engaged Sargon Engineering to prepare a Concept Study leading to a Pre-feasibility Study. WDR needed to determine a conceptual framework for the Project that identified key performance indicators, greatest areas of risk, and project economics. The requirements for the Project were:
- A mine plan
- A beneficiation plant to upgrade low grade ore to a saleable product
- Reliable infrastructure
Sargon Engineering addressed the following:
- Ore testwork and characterisation
- Optimum process route for hematite fines beneficiation
- Tailings preparation, handling and storage
- Optimum logistics (export) corridor (slurry pipeline, dewatering facilities and transhipping)
- Infrastructure, including pipelines, power station, accommodation village, airport and port facilities.
- Mine services
- Plant utilities
The Concept Study outlined likely process options and indicative project economics of each. It also highlighted various options for Project infrastructure and logistics, providing recommendations for a staged entry over 8 years.
Significant results from WDR’s drilling program have recently been made available to Sargon Engineering. Study Phase II (Scoping) is now underway, with a testwork programme being carried out at AMMTEC, which will identify grade vs. recovery of various ore types. These results will underpin the selected process option.
