Iron (Fe) is a metallic element which constitutes about 5% of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4).
Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite mineral contains 69.9% iron. It has been the dominant iron ore mined in Australia since the early 1960s and approximately 96% of Australia's iron ore exports are high grade hematite, most of which has been mined from deposits in the Hamersley province in Western Australia (WA). The Brockman Iron Formation in the Hamersley province is a significant example of high grade hematite iron ore deposits.
Magnetite is an iron oxide mineral generally black in colour and highly magnetic, the latter property aiding in the beneficiation of magnetite ores. Magnetite mineral contains 72.4% iron, which is higher than hematite but the presence of impurities results in lower ore grade, making it more costly to produce the concentrates used in steel smelters. Magnetite mining is an emerging industry in Australia with large deposits in the Pilbara region of WA being developed.
The largest project, which has a current value of more than $6 billion, is the Sino Iron project being developed by the Chinese company CITIC Pacific. Other major magnetite projects include the $2.6 billion Karara joint venture project, which is owned by Gindalbie Metals and Chinese steel producer, Ansteel, and the $2.8 billion Southdown magnetite project owned by Grange Resources. Sino Iron project is gearing up for commencement of production while the Karara Magnetite Iron Ore Project commenced production of magnetite concentrate in December 2012. Grange Resources' Southdown Magnetite development at Albany WA was planned to start in 2015 but that may change due to the current economic environment.
Mining and processing hematite and magnetite ores
High grade hematite ore is referred to as direct shipping ore (DSO) because it is mined and the ores go through a relatively simple crushing and screening process before being exported for use in steel making. Australia's hematite DSO from the Hamersley region in WA averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but undergo a second stage of processing that relies on the magnetic properties of the ore and involves magnetic separators to extract the magnetite and produce a concentrate.
Further processing involves the agglomeration4 and thermal treatment of the concentrate to produce pellets which can be used directly in blast furnaces, or in direct reduction steel making plants. The pellets contain 65% to 70% iron, which is a higher iron grade than hematite DSO currently being exported from the Hamersley region. Additionally, when compared to hematite DSO, the magnetite pellets contain lower levels of impurities, particularly phosphorous, sulphur and aluminium. These pellets are premium products which attract higher prices from steel makers, offsetting the higher costs of producing magnetite pellets.
Worldwide production trends
Hematite ores dominate the world production of iron ores and are sourced mainly in Australia and Brazil. Magnetite is increasing its presence in world production and this trend is likely to increase when large magnetite projects such as the Karara Iron, Southdown magnetite and Sino Iron projects are operational.
During 2011, China was the world's largest producer of iron ore with 43%, or 1200 million tonnes (Mt) followed by Australia with 17% or 488 Mt and Brazil with around 14% or 390 Mt of world production.
Map showing locations of Australia hematite and magnetite deposits and total resources are at :
In previous years, Geoscience Australia reported estimates of Australia's national resources of iron as tonnes of iron ore because these resources were dominantly hematite ores. However, as a result of on-going exploration and assessment of magnetite deposits, Australia has now identified substantial reserves and resources in both hematite and magnetite ores. Because of the high average grades (% Fe) of hematite ores when compared to the average grades for magnetite ores, it is necessary to report national resources in terms of contained iron. Accordingly, Australia's national resources of iron are now reported in two categories:
- Tonnes of iron ore, and
- Tonnes of contained iron.
Iron ore: In 2011, Economic Demonstrated Resources (EDR) of iron ore increased by 9% to 37 762 Mt, mainly as a result of resource increase for some deposits, including in the WA mines, BHP Yandi, Mining Area C, Nullagine, Hamersley and Hope Downs. Resource definition of existing deposits and the inclusion of new magnetite deposits have also contributed to the increase in EDR. Paramarginal Demonstrated Resources have increased from 700 Mt to 1414 Mt. The Inferred Resource increased by 29% to 61 489 Mt, mainly because of increases in some deposits in the Hamersley and Mining Area C mine operations. The inclusion of new and newly defined resources for existing deposits also contributed to the increased Inferred Resources for 2011. Western Australia has about 94% of Australia's total Identified Resources of iron ore with the majority of the resources occurring in the Pilbara Region.
However, South Australia (SA) is emerging as the second largest producer of iron ore in Australia, accounting for more than 5% of the total EDR. Australia's EDR has a resource life of 77 years. Figure 8 and Figure 9 show iron ore EDR and Inferred resources for each State and for the Northern Territory.
Contained Iron: As at December 2011, Australia's EDR of contained iron was estimated to be 18 152 Mt while Paramarginal Resources were 501 Mt and Inferred Resources were 29 204 Mt.
Australia has Accessible EDR (AEDR) of iron ore totalling 37 762 Mt, of which 94% occurs in WA.
The total Joint Ore Reserve Committee (JORC) Code Reserves of iron ore were estimated to be 15 032 Mt, representing 40% of accessible EDR. Contained iron is 7804 Mt, or 43% of the EDR. However, unreported reserves and resources are not included, resulting in a loss of accountability. Based on the data which is publicly available, JORC Code Reserves are sufficient for approximately 31 years at the current rate of mine production.
Several companies have reported initial resources on either new or known deposits that are now being drilled for resource development which have contributed to Australia's iron ore resource base for 2011. These deposits include the Nyidinghu (Fortescue Metals Group Ltd), McCamey's North (Atlas Iron Ltd), Weckl and Buckland Hills (Aquila Resources Ltd), Byro FE1 (Athena Resources Ltd), Mount Alexander (Zenith Minerals Ltd), Cohen (Buxton Resources Pty Ltd), Mount Philp (Cerro Resources NL), Muster Dam (Minotaur Exploration Ltd), Peak Hill (Padbury Mining Ltd JV), Area C, Robinson Range Iron Project (PepinNini Minerals Ltd), Feral, Perenjori Iron Ore project (Quest Minerals Ltd) and Die Hardy (Radar Iron Ltd). These deposits are a few of the new deposits that were reported and some are discussed in 'Industry Developments' section of this report.
Australian Bureau of Statistics (ABS) data indicates that iron ore exploration expenditure in Australia for 2011 totalled $905.3 million, a 64% increase on the $553.1 million spent in 2010. About $802.4 million was spent on iron ore exploration in WA which represented 89% of total iron ore exploration expenditure. Western Australia also accounted for 25% of the total mineral exploration expenditure in Australia during 2011, which amounted to around $3573.3 million. Iron ore exploration expenditure in SA was $63.5 million, Northern Territory (NT) $30.0 million and Tasmania (Tas) was $1.5 million.
Australia's total production of iron ore for 2011 was 488 Mt with WA producing 474 Mt, or 97% of overall production. South Australia increased its iron ore production from approximately 9.2 Mt in 2010 to just over 10 Mt for 2011, which represented 2% of Australia's total production of iron ore. South Australia's iron ore resource is small when compared with Western Australia, but it is emerging to become the second major iron ore producing State.
The Bureau of Resources and Energy Economics (BREE) reported Australia's iron ore exports during 2011 to be 439 Mt, a 9% increase from 2010 of approximately 402 Mt. BREE has forecast an increase in iron ore exports of at least 12% or 493 Mt in 2012 and around 6% or 525 Mt in 2013. Project expansions by large operations such as Rio Tinto and BHP to medium operations by the Fortescue Metals Group will support these projected increases. The anticipated large magnetite project production by Sino Iron also is included in the predicted increases. The predictions are a direct response to increasing consumption from developing countries such as China, India and Brazil. BREE forecast an increase in steel consumption between 2013-17 by China (4% per year), India (7% per year) and Brazil (3%) as a result of major infrastructure, rail, highways, and public housing developments. The iron ore industry has echoed the sentiment of an increase in global demand, but is expecting a slower rate of growth.
Australia has the world's largest EDR with 22% of the world's iron ore followed by Brazil with 17%, Russia with 15% and China with 14%. In terms of contained iron, Australia has 22% of world EDR while Brazil has the second largest EDR with 20%.
Rio Tinto Ltd: Rio Tinto US$15 billion investment for its five years growth program which started in 2010 has been the centre of events during the 2011. The company's growth expansion for its Pilbara operations will include, but is not limited to, the Brockman 4 mine increasing capacity from 22 Mt to 40 Mt per annum (Mtpa), extending mine life at Marandoo Mine to 16 years and increasing to 15 Mtpa capacity of the new open cut mine at Hope Downs 4. These expansion projects are aimed at increasing Rio Tinto's production to 353 Mtpa by 2015. The first stage for 225 Mtpa production capacity was achieved during the first quarter of 2011.
An additional highlight for Rio Tinto was the approval by the Western Australian Government of the company's infrastructure project planned for the town of Wickham. This project will give more support to the company's growth program by providing accommodation for the project's workforce. The government states that this infrastructure development will compliment the State's Pilbara cities initiative. Rio Tinto says that the planned infrastructure and company expansion will enable it to meet the anticipated increase in demand from the Chinese steel industries, initially from its current production of 700 Mtpa and later through growth to around one billion tonnes per annum towards 2030.
BHP Billiton Ltd: The company's Western Australia Iron Ore (WAIO) reported a record production for the year ended December 2011, raising its annual capacity to 178 Mtpa. One of the highlights for 2011 was the company's approval for the development of the new Orebody 24 mine in the Pilbara region of WA which is reported to be worth US$822 million. The development will include infrastructure such as an ore crushing plant, train loadout facility, rail spur and other supporting facilities. The new mine has a projected capacity of 17 Mtpa and will help to maintain the company's Mount Newman joint venture operations production output contributing to BHP's near term production target of 350 Mtpa. Completion of the Rapid Growth Project 5 (RGP5) expansion projects will also contribute to the anticipated increase production capacity to 220 Mtpa . BHP reported that the initial production from RGP5 occurred during the third quarter of 2011.
Infrastructure development projects which will service the WAIO operations are in progress but large capital projects such as the outer harbour project have been delayed in favour of developing the inner harbour expansion project. This change follows an evaluation by BHP which demonstrated the cost benefit of expanding the existing inner harbour. The expansion will include the development of two additional berths which, according to the company, will increase the inner harbour capacity to 220 Mtpa. It is anticipated that the commissioning of the inner harbour will be in the second half of 2012.
Fortescue Metals Group (FMG): In October 2012, FMG announced the commissioning of its 25 Mtpa second Ore Processing Facility (OPF) at Christmas Creek 110 km north of Newman in the Pilbara region. The company reports that the second OPF will lift the capacity of Christmas Creek mine to 50 Mtpa which will result in combined output of Christmas Creek and nearby Cloudbreak to 95 Mt by end of 2012. This development marks another milestone in the company's expansion plan to increase production capacity to 115 Mtpa by end of the first quarter in 2013 through the addition of the anticipated first ore production from the Solomon Firetail mine. The company has also announced initial reserves for the Solomon Hub of approximately 716 Mt. These reserves are a compilation of several deposits, including 200.9 Mt at the Firetail mine.
CITIC Pacific Ltd: When commissioned, the company's Sino Iron project will be Australia's largest magnetite iron ore development project. The project will have six production lines with the capacity to produce a total 24 Mtpa of magnetite concentrate. The company reports that some of the project supporting infrastructure has been completed, including a 30 km slurry pipeline, while integration of a power station, desalination plant and the port area are ready for commissioning. The first of the six production lines is in its final phase and work on the second production line has started.
Atlas Iron Ltd: The company has announced development and expansion plans for its Horizon 1 Growth Program categorised into three phases. The initial phase will include expansion of the pit for its existing Wodgina operation and the development of a new Mount Dove mine approximately 70 km south of Port Hedland and the Abydos mine 130 km south of Port Hedland. The company anticipates production growth of 10 Mtpa by 2013 once Mount Dove and Abydos are operational. Phase 2 of the Horizon 1 development will bring the company's production capacity to 12 Mtpa through its joint venture (with Altura Mining Ltd) Mount Webber mine project.
Gindalbie Metals Ltd: The first production of magnetite concentrate by Karara Iron Ore Project was announced in November 2012. The Karara Iron Ore Project is being developed by Karara Mining Limited, which is a 50:50 Joint Venture between Gindalbie Metals and Chinese steel producer, AnSteel. The company is currently ramping up production towards a target rate of 8 Mtpa. Gindalbie also reported a 1.5 billion tonne initial resource for the Lodestone magnetite project in 45 km southeast of the Karara project in WA's mid-west region. The company reports that, based on initial analysis, the Lodestone project has the potential to produce a magnetite concentrate grading at more than 63% iron with low impurities. The company also says that the Lodestone project can potentially become one of its stand-alone mine operations in the future.
Brockman Resources Ltd: Environmental approval for the development of the company's Marillana Iron Ore Project was received from the Department of Sustainability, Environment, Water, Population and Communities (DSEWPaC) and from the Western Australian Environmental Protection Authority. To date, the company has focused on securing rail and port infrastructure for the project and has formed an alliance agreement with QR National Ltd and Atlas Iron Ltd to conduct pre-feasibility and definitive feasibility studies for integrated mine, rail and port logistics for the East Pilbara region. Subject to the pre-feasibility study results, the alliance aims to complete the definitive feasibility study by 2013 with relevant infrastructure completed by 2016. The Marillana Iron Ore Project is located approximately 100 km northwest of Newman in the Pilbara region.
Cashmere Iron Ltd: The company has announced that it has entered an agreement with Esperance Ports Sea and Land for access to the expanded port at Esperance in the Great Southern region. The agreement allows for an allocation of 5 Mt once the port expansion occurs and a commercial agreement is reached between Cashmere Iron and the port operator. The company says that the agreement is important for the development of its Cashmere Down iron ore project. In its Annual Report, Cashmere Iron stated that three potential types of materials (hematite DSO, detrital iron deposit and magnetite) have been identified at Cashmere project which can be produced to marketable iron ore products. The company has reported Cashmere Down JORC Code compliant Resources of 1059 Mt (Measured 202 Mt, Indicated 779 Mt and Inferred 78 Mt).
Australasian Resources Ltd: The company has increased its rights to mine approximately one billion tonnes of iron ore at its flagship Balmoral South Iron Ore Project about 80 km southwest of Karratha. This was through a memorandum of understanding with its main share holder, Mineralogy Resources Ltd. In return, Mineralogy Resources earned a 50% interest in the Australasian Resources wholly owned subsidiary, International Minerals Pty Ltd. Another highlight for Australasian Resources has been the completion of the Balmoral South feasibility study update carried out by Promet Engineers, a lead consultant in the original feasibility study in 2008.
Flinders Mines Ltd: The Mining Lease for two tenements (Blacksmith and Anvil) at the company's Pilbara Iron Ore Project was granted during the year. The project is located about 60 km northwest of Tom Price in the Pilbara region. The company reports that the project's ongoing definitive feasibility study will continue to focus on mine planning, metallurgical testing and marketing. The project will produce up to 15 Mtpa of iron ore with the company reporting a current iron ore resource of 917 Mt at 55.2% Fe.
Venus Metals Corporation Ltd: The pre-feasibility study of the company's joint venture Yalgoo Iron Ore Project has indicated a technically viable and financially robust project. Located in the Yilgarn region of WA, the project has a JORC Code compliant magnetite resource of 698.1 Mt made up of 311.2 Mt Indicated Resource and 386.9 Mt Inferred Resource. Venus Metals reports that the pre-feasibility study was based on annual production of 7.5 Mtpa of magnetite concentrate grading 68% Fe for a mine life of more than 15 years.
Mindax Ltd: In April 2012, the company announced that a scoping study had been completed for the Mount Forrest Iron Project which is in the Yilgarn region about 650 km from the port of Esperance. The study considered two options for product types, beneficiated magnetite and beneficiated hematite direct shipping ore. Mindax stated that the study indicated a potentially robust project for Mount Forrest. The magnetite option was based on a 10 Mtpa production of magnetite concentrate for a mine life of approximate 18 years. Relative to this option, the company has reported a JORC Code Indicated Resource of magnetite totalling 248.2 Mt at 32.6% Fe and a JORC Code Inferred Resource of 14 624 Mt at 31.6% Fe.
Iron Ore Holdings Ltd (IOH): A pre-feasibility study for the company's Bungaroo South Project in the Pilbara region has confirmed the technical and financial viability for a 4 Mtpa to 8 Mtpa operational capacity. The signing of the Native Title agreement and approval of the mining lease for the Bungaroo South and Dragon deposits also added to the company's highlights during the year. The company says that the completed pre-feasibility study has confirmed that the new Bungaroo South mine will have an operational potential of 4 Mtpa to 8 Mtpa. In November 2012, the company has reported a total of 282.5 Mt of JORC Code Indicated (179.7 Mt at 58% Fe) and Inferred (68.6 Mt at 55.1% Fe) Resources for the Bungaroo South deposit.
Pluton Resources Ltd: Mining lease approval has been granted to the company's Irvine Island project which is located about 130 km north of Derby on the Kimberley Coast of WA.

The company now aims to complete the acquisition of data required to gain government approval for the Irvine Island development.
FairStar Resources Ltd: The company has entered into a Native Title agreement with the Central East Goldfields Peoples Native Title Claimant Group and has been granted a mining lease for on-going exploration and production at the its Steeple Hill Iron Project in WA's eastern goldfields. FairStar state that this is a significant milestone for the company's commitment to bring the Steeple Hill project to the production stage. In June 2011, the company has reported new Indicated Resources for Steeple Hill of approximately 136 Mt of hematite at 58% Fe grade.
Golden West Resources Ltd (GWR): Mining approval was received for the company's John William deposit, which is part of its Wiluna West Project. The approval allows the company to mine up to 1 Mtpa for a three year period. GWR has reported a global resource for the Wiluna West Project of 130.3 Mt at an average grade of 60% Fe. Part of this resource is 10.8 Mt at 64.1% Fe for the John William DSO hematite deposit. Effort to secure port access is a priority for the company.
BC Iron Ltd: A significant milestone for the company's Nullagine joint venture with Fortescue Metals was achieved in December 2011 when more than 1 Mt of iron ore was exported to exceed the company's export target. Another target milestone was a production rate of 3 Mtpa which was increased to 5 Mtpa in May 2012, well ahead of the end of June 2012 target. In addition, the joint venture exported approximately 224 000 wet tonnes of iron ore from Port Hedland's Herb Elliott Port, which was its largest ever shipment.
Cazaly Resources Ltd: The company's Parker Range Iron Ore project about 400 km east of Perth has received environmental approvals, clearing the way for its development.

The company's Annual Report states that the Gum Flat project draft mining lease application was completed, and project planning and background studies, including a community consultation process, is ongoing. Stage 2 consists of mining the magnetite resource for a 10 Mtpa mine capacity over a mine life of approximately 20 years. The magnetite ore will be beneficiated on site to produce approximately 2.5 Mtpa of high grade magnetite concentrate for export through Port Lincoln or Port Spencer.
IronClad Mining Ltd: The company reported that ongoing resource definition drilling at the Wilcherry Hill Iron Ore project, about 40 km north of Kimba on northern Eyre Peninsula, is well underway to further delineate the near surface DSO for low cost mining and ore processing. IronClad Mining states that, in the current economic environment, reduced mining cost of the DSO, and the low cost of other materials suitable for upgrade by dry magnetic separation, will be economically beneficial for the Wilcherry Hill project.
Apollo Minerals Ltd: During 2011-12 year, the company reported an initial resource of 72 Mt grading at 25.9% Fe for the Sequoi deposit within its prospective Commonwealth Hill Iron Project, 90 km to the north of Tarcoola. The deposit is made up of 19.4 Mt at 27.7% Fe Indicated Resources and 52.6 Mt at 25.3% Fe Inferred Resources. Based on a recent ground magnetic survey, there is a potential expansion of the exploration target for the Sequoi deposit to between 100 and 150 Mt grading between 25 and 35% Fe.

Carpentaria Exploration Ltd: The company announced an increase in its Hawsons Iron Project present nett value to $3.2 billion following an update of a pre-feasibility study based on a mining optimisation study. The company states in its Annual Report that the mining option study includes revised mining production schedules, reduced stockpiles and in-pit crushing as well as using a conveying system instead of truck haulage. With a development partner, Carpentaria Exploration plans to launch the bankable feasibility study for Hawsons project this year, it expects to complete within two years. The Hawsons Iron Project, which is located 60 km southwest of Broken Hill, has current Inferred Resource of magnetite of approximately 1.4 billion tonnes at DTR grade of 15.5% Fe3O4 with a 12% cut-off grade.
Grange Resources Ltd: The company reported in early 2012 that it had a 75% increase in the mineral resources at its Southdown Magnetite Project 90 km from Albany, Western Australia. The 1.2 billion tonnes resource increase was the outcome of a definitive feasibility study resource definition drilling program. The company has also revised to 2015 for the anticipated start of the project but has maintained the production capacity of 10 Mtpa for a 14 year mine life. The company has also obtained the final major environmental permit for the project's desalination plant. The company says that with all major permits for the Southdown project in place, the project can initiate the development phase when the current market and economic environment improves.
Shree Minerals Ltd: A pre-feasibility study of the company's Nelson Bay River Iron Project 70 km southwest of Smithton, was completed and reported in early 2012 and confirmed the viability of the project. The company has identified three resource types, which include hematite DSO, Beneficiable low-grade goethite-hematite ore and magnetite ore. The company has reported DSO reserves of 0.33 Mt at 57.4% Fe.
Sherwin Iron Ltd: An application for a mining lease for the Sherwin Creek Deposit C about 475 km southeast of Darwin was lodged by the company during 2012. The company states that ongoing pre-feasibility study infill drilling has resulted in the 100% upgrade of the Area C deposit Inferred Resources resulting in Indicated Resource of 18.3 Mt. Subject to a positive outcome of the project pre-feasibility study, Sherwin Iron anticipates producing an initial DSO of approximately 3 Mtpa from the Area C deposit.
Western Desert Resources Ltd: A total of five mining leases were granted for the Company's Roper Bar Iron Ore Project about 60 km south of Ngukurr and 50 km from the Gulf of Carpentaria coast. The company also achieved a Native Title Agreement with the Northern Land Council (NLC), Native Title Holders as well as a Load Facility Agreement with Mount Isa Mines Ltd which provides access to an area on Mount Isa Mines Mineral lease at Bing Bong in the Gulf of Carpentaria.

4 Agglomeration is the process in which magnetite grains are aggregated into pellets using a chemical binding reagent. Pellets are produced in a pelletising plant.
5 Davies Tube Recovery (DTR) testing is a laboratory technique which uses a Davis Tube to recover magnetic particles from an ore samples. The per cent mass recovery of magnetic material is determined from the mass of sample recovered compared to the sample mass. The recovered magnetic and non-magnetic portions can be analysed for chemical composition (taken from Minotaur Exploration report explanatory notes).
