The Thalanga Base Metal Operation (Thalanga) is located approximately 55km west of Charters Towers in Northern Queensland, Australia and is 100% owned by Red River Resources Limited.

Thalanga Location


Thalanga Base Metal Operation


The Thalanga polymetallic massive sulphide deposit was discovered in 1975 and production commenced in 1989. The pre-mining resource was 6.35 Mt @ 2.2% Cu, 3.9% Pb, 12.3% Zn, 99 g/t Ag & ~1-2 g/t Au, and the Thalanga deposit was mined by open pit and underground operations. Production from the Thalanga deposit ceased in 1998, and the mining operations were placed on care & maintenance when the Thalanga mill was converted to process high grade copper ore from the nearby Highway-Reward deposit.

From 1998 to 2005, 3.2Mt @ 6.2% Cu & 1 g/t Au of copper ore from Highway-Reward was processed through the Thalanga Mill. When mining activities ceased at Highway-Reward in 2005, the Thalanga Operation was placed on care & maintenance.

Kagara acquired the Thalanga Operation in 2006, and restarted production, initially processing copper ore from the Balcooma deposit, then refurbishing the Thalanga mill to treat polymetallic massive sulphide ore (producing separate copper, lead and zinc concentrates) from Thalanga. Kagara placed the Thalanga Operation on care & maintenance and then subsequently went into voluntary administration in early 2012.

Thalanga was acquired by Red River from the Kagara liquidators in 2014 for A$6.5 million.

Current Operations

Red River commenced mining operations at the West 45 UG polymetallic high-grade massive sulphide deposit in April 2017, and the Thalanga Mill commenced processing the West 45 ore to produce separate copper, lead and zinc concentrates in September 2017.

Red River announced a maiden JORC Resource for the polymetallic high-grade massive sulphide deposit at Far West in January 2015 and the first ore from the Far West UG mine was processed through the Thalanga Mill in March 2019. Red River ceased production at West 45 in February 2020 (ore body mined out) and Far West will be the main source of ore for the Thalanga Mill until the Liontown Project is developed.

To date, Red River has processed in excess of 1Mt of ore from the West 45 and Far West deposits at Thalanga.

First Concentrate Produced at Thalanga by Red River

Copper concentrate produced at Thalanga is sold to Glencore at the Thalanga mine gate. The lead and zinc concentrates are trucked to the Port of Townsville where they are sold to Trafigura.


Thalanga consists of a 650ktpa capacity milling facility which produces separate copper, lead and zinc concentrates.Thalanga employs approximately 160 employees and contractors on a local residential basis and the majority of the workforce resides in Charters Towers.




Power at Thalanga is supplied by a 66kV connection to the Queensland power grid. The site water requirements are supplied from on site water storages and recycling water used in the processing plant. Thalanga also sources additional water from a bore field.

Thalanga Operational Life

Thalanga currently has an estimated operational life of approximately 10 years based on the Far West UG operation and the Liontown Project.

Far West is an UG mechanised mine with an estimated mine life of 5 years+. Far West has a current Ore Reserve of 1.4Mt @ 1.4% Cu, 1.7% Pb, 5.1% Zn, 0.3 g/t Au & 49 g/t Ag (12.6% Zn Eq.) and a Mineral Resource of 1.7Mt @ 1.6% Cu, 2.2% Pb, 6.4% Zn, 0.3 g/t Au & 61 g/t Ag (15.3% Zn Eq.)

The Liontown Project has a current Mineral Resource of 4.1Mt @ 0.6% Cu, 1.9% Pb, 5.9% Zn, 1.1 g/t Au & 29 g/t Ag (12.7% Zn Eq.) Liontown has a high grade gold component (1.1 g/t Au, 152koz Au contained).

Red River is currently developing Liontown as Red River’s 3rd mine at Thalanga. Liontown will be an open pit / UG mine with a conceptual mine life of 10+ years
