Deposit Type

  • Carbonate replacement
  • Skarn


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 shallow-dipping dolomite horizons which host replacement 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 cont ........


Mining Methods

  • Bench stoping
  • Open stoping
  • Cemented backfill


Summary:

The Renison Tin Mine (Renison) is located approximately 15km north-east of Zeehan on Tasmania’s west coast. Renison is a world-class, long life underground mining operation producing tin concentrate.

The Renison mine predominantly applies up-hole benching and open stoping mining methods with (in some cases), post fill and cemented rock fill to fill voids. The weighted average mining dilution is 14% at zero grade. Minimum widths for underground development are 4.5m and for stoping minimum widths are 2.2m.

RENISON TAILINGS RETREATMENT (RENTAILS) PROJECT
The objective of the Rentails Project is to re-process the estimated 22.5 Mt of tailings at an average grade of 0.44% tin and 0.23% copper from the historical processing of tin ore. The current tailings dams have a Mineral Resource containing approximately 104,000 tonnes of tin and 53,000 tonnes of copper (refer to ASX announcement dated 30 January 2020).
