Table 1: Operating Mines
Table 1. Australia's Ore Reserves and Mineral Resources of selected commodities at operating mines in 2017
This table provides short-term (Ore Reserves) and long-term (Mineral Resources) views of Australia's minerals inventory at operating mines. For further information about Australia's minerals inventory see Table 2 (Australia's Ore Reserves) and Table 3 (Australia's Identified Mineral Resources and World Figures). See Table 5 (World Rankings) for a global outlook on Australia's production and resources and see Table 6 (Reserve and Resource Life) for an indication of Australia's potential to continue supplying minerals.
|Commodity||Unit||No. of Operating Mines1||Ore Reserves2||Measured and Indicated Mineral Resources3||Inferred Mineral Resources4||Mine Production5||Reserve Life (years)||Resource Life 1 (years)||Resource Life 2 (years)|
|Black Coal||Mt||91||12 713||28 2427||11 8427||5598||23||51||72|
|Iron Ore||Mt||33||9424||17 470||31 739||883||11||20||56|
t = tonne; kt = kilotonnes (1000 t); Mt = million tonnes (1 000 000 t); Mc = million carats (1 000 000 carats).
Where an element symbol follows the unit it refers to contained metal content.
Reserve Life = Ore Reserves ÷ Production.
Resource Life 1 = Measured and Indicated Resources ÷ Production.
Resource Life 2 = Measured, Indicated and Inferred Resources ÷ Production.
1. The number of operating mines counts individual mines that operated during 2017 and thus contributed to production. Some of these mines may belong to larger, multi-mine operations and some may have closed during or since 2017.
2. The majority of Australian Ore Reserves and Mineral Resources are reported in compliance with the JORC Code, however there are a number of companies that report to foreign stock exchanges using other reporting codes, which are largely equivalent. In addition, Geoscience Australia may hold confidential information for some commodities. NB: Not all operating mines report Ore Reserves. Ore Reserves are as at 31 December 2017.
3. Measured and Indicated Mineral Resources are inclusive of the Ore Reserves. NB: Not all operating mines report Mineral Resources. Mineral Resources are as at 31 December 2017.
4. Inferred Mineral Resources are as at 31 December 2017. NB: Not all operating mines report Mineral Resources.
5. Source: Resources and Energy Quarterly, June 2018, published by the Office of the Chief Economist, Department of Industry, Innovation and Science unless otherwise stated. Production data often have a higher level of certainty than reserve and resource estimates and, thus, may be presented with more significant figures.
6. Antimony production from company reports.
7. Measured, Indicated and Inferred Mineral Resources for black coal are presented on a recoverable basis (these are Geoscience Australia estimates unless provided by the company).
8. Mine production refers to raw coal.
9. Lithium production is a Geoscience Australia estimate based on Mineral and Petroleum Statistics Digest 2016–17, published by the Department of Mines, Industry Regulation and Safety, Western Australian Government.
10. Manganese production from company reports. Minimum estimate as Woodie Woodie production unknown.
11. Mineral sands production from company reports.
12. Rare earths comprise rare earth oxides (REO) and yttrium oxide (Y2O3).
13. Rare earths production from company reports.
14. Major silver producing mines only; many gold and copper mines also produce silver as a by-product but these are not counted here.
15. The Office of the Chief Economist report tin production of 7.4 kt in 2017, however the sole operating mine (Renison Bell) reports 7.1 kt. The remainder is by-product from other operations such as Greenbushes.
