The West 45 deposit is the first to be mined at Thalanga as part of the recommencement of concentrate production. It consists of five semi‐massive to massive sulphide lenses rich in zinc and lead.
West 45 hosts a JORC Code (2012) compliant Ore Reserve of 567kt at 11.6% Zn Eq. and a Mineral Resource estimate of 582kt at 15.45% Zn Eq. using a cut-off grade of 5% Zn Eq., as at 20 December 2017.
Development and mining activities at West 45 recommenced in April 2017, with the delivery of the first ore from West 45 to the Thalanga ROM pad. Stoping commenced in September 2017, and the first load of production ore was delivered to the Thalanga ROM soon after.
PYBAR Mining Services is undertaking contract mining activities at West 45.
In addition, Red River is completing drilling at West 45, aimed at further extending the known mineralisation. Results from extension drilling are being modelled and incorporated in an updated West 45 mine schedule. Red River is also modelling the economic viability of driving a new level (976 West) above the 956 Level.
