Newmont Tanami is on Aboriginal freehold land 540km northwest of Alice Springs. It is a long-life, low-cost, world-class asset in a core Newmont region. The Tanami Expansion 2 project, aims to extend the mine life beyond 2040, investing in a hoisting shaft which will increase the production of the underground mine from 2.6 Mtpa to 3.2 Mtpa. Both the successful exploration within the underground operation and implementation of the first Tanami Expansion has laid the foundation to further develop the operation to remain a major contributor to the Newmont portfolio. A fully equipped camp is located 40km from the site offering leisure facilities for those flying in from Perth, Brisbane, Alice Springs or Darwin.
