Prospectivity
The Tanami Region has seen more than 10 million ounces of gold produced since 1986 and remains the Territory’s most significant gold producing province. Mineralisation in the Tanami is typically orogenic gold, with gold hosted in quartz and/or quartz-carbonate veins in folded carbonaceous siltstone, iron-rich sediments, turbidite, basalt or dolerite. The gold potential of the Tanami extends into the Aileron Province to the southeast with exploration targeting a range of mineralisation styles including orogenic shear-hosted gold, intrusion-related gold and iron oxide copper gold.
The Tanami region hosts Newmont's Tanami Operations, located 550km northwest of Alice Springs. It has produced >8 million ounces of gold, and remains the Territory’s largest gold operation, with remaining reserves of more than 5 million ounces. Mineralisation consists of high-grade Au-quartz veins in folded carbonaceous siltstone in the lower Dead Bullock Formation.
The Warramunga Province hosts the Tennant Creek and Rover mineral fields. Historic gold production from the Tennant Creek field totals more than 5 million ounces of gold. Small high-grade gold-copper-bismuth deposits hosted within magnetite and/or hematite-rich ironstone bodies in the Palaeoproterozoic Warramunga Formation are typical in the Tennant Creek mineral field and the undercover Rover mineral field, 70km to the southwest, beneath the overlying Wiso Basin. Substantial exploration commenced in 2021 for undercover gold and copper-gold mineralisation in undercover extensions of the Tennant Creek mineral field in the Barkly Tableland east of Tennant Creek, after significant investment in pre-competitive data acquisition by Geoscience Australia's EFTF, MinEx CRC and NTGS. Exploration in 2024 remains very strong.
The Pine Creek Orogen has a 150 year history of gold mining with more than 4 million ounces of gold produced. Most deposits are orogenic gold deposits in the Palaeoproterozoic Cosmo Supergroup, with gold most commonly hosted in-quartz veins, lodes, sheeted veins, stockworks and saddle reefs, with some gold also hosted within iron-rich sediments. Gold also occurs with zinc and silver associated with volcanic-associated massive sulphide deposits.
A number of gold projects in the Pine Creek Orogen are well advanced towards potential production, including a high-grade underground project at Toms Gully, the 8 million ounce Mount Todd gold project near Katherine, and the polymetallic Hayes Creek project.

Mines
Newmont's Tanami Operations is located 550km northwest of Alice Springs and commenced mining in 1986. Mineralisation consists of high-grade Au-quartz veins in folded carbonaceous siltstone in the lower Dead Bullock Formation. The operations include the Callie deposit (>7.6 Moz), the 5.83 Moz Auron deposit, the Federation South Limb and the Liberator deposit, with gold endowment at the mine of more than 9 Moz at the end of 2023. Gold is processed at a plant at The Granites, 40km east of the mine.
