This document discusses where future mining opportunities may be located. It notes that exploration spending is now split evenly between greenfield (new) and brownfield (existing mine) sites, down from a previous focus on greenfield. High taxation, costs, and difficulties raising capital make Australia less competitive for mining investment. The quality of Australia's geoscience database is praised but challenges remain such as deeper, more remote deposits and workforce issues. The Northern Territory is highlighted as having competitive policies and rising exploration but more certainty is still needed to encourage investment. A national response is required to improve competitiveness through tax reform and other policies.
