The West 45 deposit consists of five semi‐massive to massive sulphide lenses at various stratigraphic positions within the host Quartz Eye volcaniclastic unit. They are dominantly Zn‐Pb rich and low in Cu‐Fe. The West 45 portal is located approximately 2km west of the Thalanga Mill.

In July 1996, RGC Thalanga Pty Ltd commenced the Thalanga Range Exploration Programme searching for additional mineralised zones along strike from the Thalanga Cu‐Pb‐Zn‐Ag‐Au mine. Exploration hole TRRC082 was designed to follow up promising geochemistry from hole TH45. The resultant intersections of 2m at 13.5% Zn, 3.1% Pb 1.1% Cu and 4m at 5.1% Zn, 1.1% Pb and 0.2% Cu were encouraging, and the prospect 1.8km northwest of and along strike from the Thalanga Central Pit was named West 45.

At the start of 2017, Red River engaged PYBAR Mining Services (PYBAR) as the UG mining contractor for West 45. PYBAR are an Australian based and owned underground mining contractor with a long track record in metalliferous underground mining contracts within Australia, and have an outstanding reputation in terms of safety, execution and quality.

Development and mining activities at West 45 recommenced in April 2017, nearly 5 years after the previous operator ceased activities with the delivery of the first ore from West 45 to the Thalanga ROM pad.West 45 is expected to ramp up to design production rates by late Q3 2017.

West 45 hosts a JORC Code (2012) compliant Mineral Resource of 591kt grading 0.6% Cu, 3.5% Pb, 8.3% Zn, 0.3g/t Au and 69g/t Ag. The resource estimate was completed by Mining One Consultants in January 2015.
