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.

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.

The Thalanga Plant is designed for a nominal throughput of 650ktpa, using standard industry technology to produce saleable copper, lead and zinc concentrates via flotation. The plant flowsheet is summarised as:

- Crushing circuit (three-stage crushing circuit);
- Milling circuit (primary (x1) and secondary ball mill (x2) circuit);
- Concentrate flotation circuit (differential copper, lead and zinc flotation circuits);
- Concentrate thickening and filtration;
- Regrind circuit;
- Concentrate storage, blending and transport;
- Sub-aqueous disposal of tailings.
