INDUSTRY PERFORMANCE MEASURES
A range of performance measures, mainly expressed as ratios, can be produced from the data available from businesses' financial statements. A selection of these are presented in this Chapter for the various mining industries. Information about the uses and limitations of these measures can be found in Explanatory Notes paragraphs 36-40.
The following summarises the mining industry's performance ratios for 2006-07, which appear in detail in table 2.1:
- The highest profit margins were recorded by Iron ore mining (60%) and Oil and gas extraction (52%). Gold ore mining remained the industry with the lowest profit margin in 2006-07 (2%).
- The interest coverage in 2006-07 was highest for Silver-lead-zinc ore mining and Copper ore mining.
- The highest value of IVA to selected labour costs occurred in the Oil and gas extraction industry, where IVA exceeded selected labour costs by 15.2 times. The next highest value (11.9 times) occurred in Iron ore mining. The Exploration and other mining support services shows the lowest value (1.1 times) for this ratio.
- Of all mining industries shown, Oil and gas extraction (at $144,000) recorded the highest selected labour costs per person employed, followed by Iron ore mining ($143,000). For total mining, the estimate was $110,000.
- Exploration and other mining support services recorded the highest investment rate (value added) of 88.7% in 2006-07, with Gold ore mining recording the next highest value (66.6%).
