Thalanga 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 bas ........

Summary:
Red River acquired the Thalanga Operation in 2014 and commenced production from the West 45 deposit in 2017. Production from West 45 ceased in 2020 and ore for the Thalanga Operation is currently being sourced from the Far West underground mine, with plans to develop the Liontown deposit to extend the operational life of Thalanga.
As per West 45, Far West will be mined using long hole stoping (LHS), based on the advice provided by the independent technical consultant, Mining One. This method is well suited to a resource with the dip, width and desired production rate of Far West. Stope backfill will be a combination of cemented rock fill (CRF) and unconsolidated waste rock fill, which enables a high recovery of ore, removing the need to leave pillars within the orebody, and also utilising the waste rock.
Total Far West UG capital development in FY20 was 2,446m for the period (954m lateral capital development, 1,131m decline development and 361m vertical capital development). Total development for the period was 4,270m (including operating development of 1,824m).
Red River has commenced development activities at Liontown, with the intention to commence mining at Liontown in FY23.
Project development activities commenced at the Liontown Project during the period of 2020. Red River is focusing on an open pit / UG development for the Liontown Project with a conceptual mine life of 10+ years. During the period of 2020, historic tailings from Liontown were processed at Th ........
