SnapshotThalanga Operations consists of a 650ktpa capacity processing plant. Thalanga Operations commenced production from the West 45 deposit in 2017. Ore for the Thalanga Operation is being sourced from the Far West underground mine, with plans to develop the Liontown deposit to extend the operational life of Thalanga.

Due to ongoing operational performance at Thalanga during October with reduced mining and mill production Red River’s subsidiary, Cromarty Resources Pty Ltd, was placed into Voluntary Administration on 28 October 2022. Post their appointment, the Administrators have determined to place the Thalanga operations on care and maintenance.

A reconvened second meeting of creditors of Red River was held on 23 August 2023, at which the creditors of Red River voted for it to be wound up.

Summary:

The Thalanga Operation is located in the highly prospective Cambro-Ordovician Mt Windsor Volcanic Belt which contains a number of known polymetallic (copper-lead-zinc +/- gold-silver) volcanic hosted massive sulphide (VHMS) deposits and gold deposits.

The West 45 deposit is located 1.7km west of the Thalanga Plant and it is ~1.4km by unsealed road from the portal to the run of mine (ROM) ore pad.

The Far West deposit is located ~500m from the ROM pad at the Plant, to the west of and directly adjacent to the historically mined Thalanga West deposit. Far West sits within existing mining leases. Much like West 45, Far West is a VHMS deposit which is of polymetallic nature and contains zinc, lead, copper, gold and silver.

The Waterloo deposit is located approximately 40km to the SSW of Charters Towers and ~50km east from the Thalanga mine. As with the West 45 and Far West deposits, Waterloo is a VHMS deposit which contains zinc, lead, copper, gold and silver. Red River intends to mine Waterloo and truck the ore to the Thalanga Plant for processing.

The Liontown polymetallic volcanogenic hosted massive sulphide deposit is located 40km southwest of Charters Towers in North Queensland. It is accessed by the Flinders Highway and the Gregory Developmental Road. Red River acquired the Liontown Project in 2014 with the acquisition of the Thalanga Base Metal Operations.

Mineralisation in the Liontown Horizon is developed in the basal siltstone unit of the hangingwall sequence, with the most consistent mineralisation lying immediately above the pumice breccia. Mineralisation is developed as multiple zones of stratiform, laminated, semi-massive and rarely massive sulphide. The Liontown host rocks comprise a footwall sequence of dacitic pyroclastics termed pumice breccia, which has been strongly silicified and chlorite altered.

Production

During the quarter 2020, approximately 13,000 tonnes of historic gold tailings were reclaimed from the Liontown Project site, trucked to Thalanga Operations and processed through the mill to produce 475 DMT tonnes of gold concentrate grading 62.3 g/t Au, 197 g/t Ag and 12.8% Cu.
