SA Mines and Energy Journal : April - May 2013
16 APRIL/MAY 2013 SA MINES & ENERGY JOURNAL FEATURE J+H WILLIAMS around 5Mtpa of high grade concentrate over 30 years. The project is unique in its inclusion of a coal mine and power station to supply its own low cost energy. Other early stage projects also remain undeterred by lower prices and challenging economic conditions. The Braemar cluster includes several large deposits along the Braemar Iron Formation, which stretches from Peterborough in SA to the NSW border. It is claimed the area could see five large open cut mines eventually producing over 50Mtpa of concentrate for around 100 years. Most projects in the region are progressing through exploration and early studies. Minotaur's Mutooroo project is in the final stages of a scoping study which has established a 1.5 billion tonne predominantly magnetite resource, to be mined at 10Mtpa for over 30 years. Tony Belperio, Executive Director Business Development at Minotaur, says the company is currently waiting on metallurgy to reveal whether the resource's hematite can also be extracted before finalising the study. Havilah is at a similar stage. The company has confirmed an inferred JORC resource at its Braemar-based Maldorky deposit of 150mt and 304mt at its Grants resource. Havilah hopes to complete a DFS this year and commence production in 2014-15, using Port Adelaide if necessary; however, a deep water facility would enable significantly expanded production. Royal Resources is also pressing ahead with studies on its Braemar project, with a resource defined at around 1.8 billion tonnes within its focus area, the Razorback Premium Iron Project. "We're currently looking to optimise capital and operating expenses before progressing to a DFS, funding dependent, later this year, " Managing Director Marcus Flis says. He says due to the State's lack of a capesize vessel capable port, the project will transport its ore via pipeline to a deep sea anchored vessel, before being de-watered onboard and transferred to capesize vessels for export. Others insist that a capesize vessel capable port located on the east side of Spencer Gulf will be required to ser vice the Braemar region, with various options under consideration including Port Pirie and Myponie Point. With the ability to inject jobs, funds and optimism in the economy -- and fuel a string of other projects -- the time to overcome our infrastructure challenges and cement SA's iron ore future could hardly be better. Operating mines Middleback Ranges and Southern Iron Cairn Hill Advanced projects Wilgerup and Fusion Wilcherry Hill Central Eyre Iron Project Operator Arrium IMX Resources Centrex IronClad Iron Road System Ore railed to Whyalla, processed and loaded to ships via barging and three loading platforms located 5, 7.5 and 8.5 nautical miles offshore. Ore transported by truck briefly then railed to port, before loading directly into ships from the wharf via container lifting and rotating crane. Ore to be transported via truck (Wilgerup) and slurry pipeline (Fusion) to port for direct loading. Land has been purchased, State government approvals in place, awaiting Federal EPBC Act approval then board approval. Ore to be trucked to storage facility then transported by barge in containers, to barge-mounted crane 7km offshore. Given the green light by SA government; offshore loading successfully trialled; funding being sought whilst awaiting State DAC approval. Ore to be railed to port for direct loading. Land has been purchased; community consultation commenced. Export options Port capacity 13 Mtpa; shallow port, two loading points accommodate cape size vessels. Currently shipping at 7 Mtpa; on track to increase to 12 Mtpa from July this year. Shallow water; two panamax vessels currently shipped each month. 20 Mtpa; Deep port accommodating panamax and cape size vessels. Centrex requires 10 Mtpa with 10 Mtpa available for others. Panamax or capesize vessels 30 Mtpa; Deep port accommodating panamax, handymax and capesize vessels. Iron Road requires 20Mtpa with 10Mtpa available for others initially - potential for future expansion.
