The mine provides limestone for our Marulan kiln, which can produce 150,000 tonnes of lime per annum. The Marulan limestone quarry has an estimated 70 years of life remaining and an output of approximately 3 – million tonnes per annum. Limestone mining began in Marulan in around 1875. The mine is loed 165 kilometres south of Sydney near
· limestone mines. The rock mass was classifed at three locations using the Bieniawski (1989) rock mass rating (RMR). The unadjusted ratings were found to range from 69 to 76, as shown in Table 2, placing the rock mass slightly below the average RMR of 75 found in the NIOSH survey of US limestone mines (Esterhuizen et al. 2006). The rock mass

Historical evidence in advanced mining jurisdictions shows that in the case of common minerals of widespread use, such as iron ore and limestone, exploration more than replaces the stock of resources consumed through mining. A case in point is Australia whose iron ore resources have increased a hundredfold in 40 years through a process
