Table 1: Operating Mines

TABLE 1. Australia's Ore Reserves and Mineral Resources of Major Commodities at Operating Mines in 2016

This table provides short-term (Ore Reserves) and long-term (Mineral Resources) views of Australia's minerals inventory at operating mines. Average reserve and resource life is the ratio of the agglomerated mine inventories to total production for 2016 and should be regarded as a snapshot in time. These ratios do not take into account future changes (positive or negative) to the minerals inventory and they assume a static rate of production. For further information about Australia's minerals inventory see Table 2 (Australia's Ore Reserves) and Table 3 (Australia's Resources and World Figures). For a global outlook on Australia's production and resources see Table 4 (World Rankings).

Abbreviations

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.

Notes
1.The number of operating mines counts individual mines that operated during 2016 and thus contributed to production. Some of these mines may belong to larger, multi-mine operations and some may have closed during or since 2016.
2.  The majority of Australian Ore Reserves and Mineral Resources are reported in compliance with the Joint Ore Reserves Committee (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. Ore Reserves are as at 31 December 2016.
3.  Mineral Resources are inclusive of the Ore Reserves. Mineral Resources are as at 31 December 2016.
4.   Source: Resources and Energy Quarterly, June 2017 published by the Office of the Chief Economist,  Department of Industry, Innovation and Science unless otherwise stated.
5.   Measured and Indicated Resources for black coal are presented on a recoverable basis (these are Geoscience Australia estimates unless provided by the company).
6.  Mine production refers to raw coal.
