ShapshotRenison is one of the world’s largest operating underground tin mines and Australia’s largest primary tin producer.

The objective of the Area 5 Project is to develop and mine the high-grade Area 5 Ore Reserve, including construction of the requisite surface and underground infrastructure to support the development. Post completion of the Area 5 Project, the annual production is expected to increase on average 10,000 tonnes of tin per annum.

The Area 5 upgrade has now been completed and the EPC contractor demobilised from site. Paste Plant commissioning challenges and failures of the underground reticulation pipework continued to impact paste delivery at the beginning of the Lune quarter 2023. These delays had been integrated into the mining schedule to minimise the impacts to the CY2023.

Summary:

Renison is the largest of three major skarn, carbonate replacement, pyrrhotite-cassiterite deposits within western Tasmania. The Renison Mine area is situated in the Dundas Trough, a province underlain by a thick sequence of Neoproterozoic-Cambrian siliciclastic and volcaniclastic rocks. At Renison there are three main shallow-dipping dolomite horizons which host replacement mineralisation. The major structure associated with tin mineralisation at Renison, the Federal Basset Fault, was formed during the forceful emplacement of the Pine Hill Granite during the Devonian and is also an important source of tin mineralisation. Mount Bischoff is the second of three major Skarn, carbonate replacement, pyrrhotite cassiterite deposits within western Tasmania. The Mount Bischoff Mine area is situated within the Dundas Trough, a province underlain by a thick sequence of Neoproterozoic- Cambrian siliciclastic and volcaniclastic rocks. At Mount Bischoff folded and faulted shallow dipping dolomite horizons host replacement mineralisation with fluid interpreted to be sourced from the forceful emplacement of a granite ridge and associated porphyry intrusions associated with the Devonian Meredith Granite, which resulted in the complex brittle/ductile deformation of the host rocks. Lithologies outside the current mining area are almost exclusively metamorphosed siltstones. Major porphyry dykes and faults such as the Giblin and Queen provided the major focus for ascending hydrothermal fluids from a buried ridge of the Meredith Granite. Mineralisation has resulted in tin-rich sulphide replacement in the dolomite lodes, greisen and sulphide lodes in the porphyry and fault/vein lodes in the major faults. All lodes contain tin as cassiterite within sulphide mineralisation with some coarse cassiterite as veins throughout the lodes. The Rentails Mineral Resource is contained within three Tailing Storage Facilities (TSF’s) that have been built up from the processing of tin ore at the Renison Bell mine over the period 1968 to 2016. Renison has currently been mined over a strike length of >1,950m, a lateral extent of >1,250m and a depth of over 1,200m. Rentails is deposited in three adjacent TSFs which have and aggregate length of approximately 1.8km and a width at the widest point of circa 1km. Maximum depth is in excess of 20m.
