Remaining JORC resources: 33.1 Mt @ 5.6 g/t Au

Newmont-Goldcorp’s Tanami Operations, located 550km northwest of Alice Springs, has produced >8 Moz of gold, and remains the Territory’s largest gold operation, with remaining reserves and resources of 5.91 Moz. 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. The total pre-mining gold endowment at the mine was 14.2 Moz at the end of 2017. Gold is processed at a plant at The Granites, 40km east of the mine.

Reserve: 0.66 Mt @ 5.0 g/t Au

Kirkland Lake Gold’s Pine Creek operations in the Pine Creek Orogen include the Cosmo Deeps underground gold mine which produced 291,462 ounces of gold from 2013 until mining was suspended in mid-2017.

The operations are in care and maintenance while a resource definition and exploration program is underway, including underground development at the newly discovered Lantern deposit at Cosmo Deeps. Kirkland Lake Gold own a 2.5 Mtpa processing facility at Union Reefs, 60km south of the mine.

Edna Beryl is a small-scale, high-grade underground gold mining operation that commenced operation in 2017. It is the first of a number of small mines in the Tennant Creek region proposed by a joint venture between Emmerson Resources Ltd and Territory Resources Pty Ltd. This also includes the refurbishment of an existing mill at Warrego as a central gold processing facility.

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.

Advanced projects

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.

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.

Gold production in the Warramunga Province has largely been sourced from the Tennant Creek field, where over 5 million ounces of gold has been historically produced from high-grade gold-copper-bismuth deposits hosted within magnetite and/or hematite-rich ironstone bodies in the Palaeoproterozoic Warramunga Formation. A similar field occurs in the Rover field, 70km to the southwest, beneath the overlying Wiso Basin.
