The richly endowed 300 horizon near surface is advantageous for open pit mining and the depth of the system is advantageous for block cave mining. Newcrest has told Tudor “the deeper the better with these sub-level block caves”. Drilling at the Calm Before The Storm, Eureka, and Perfectstorm zones has only just begun with geophysics showing potential deep roots as well.
