Emerging Australia's gold mines by production, grades

However, in terms of determining Dateline's prospects of being a low AISC producer, the key factor is its shallow high-grade mineralisation, once again providing the potential for open pit mining. The deposit contains particularly high grades, potentially ranging between 13 g/t gold and 17 g/t gold, equating to a prospective resource of between 250,000 ounces and 300,000 ounces.
