Summary:
Jaguar Operations includes four deposits including Teutonic Bore, Jaguar, Bentley and Triumph.
The Jaguar Operation mineralised deposits are classified as Volcanic Hosted Massive Sulphide (VHMS) type deposits. The deposits contain economic concentrations of copper and zinc, with gold and silver both important by-products. At the Jaguar Operation there are four Mineral Resource deposits including Teutonic Bore, Jaguar, Bentley and Triumph. Current mining activities are focused at the Bentley deposit.
Jaguar Operation is centred on a cluster of Volcanic Hosted Massive Sulphides (VHMS) deposits that are located within the Gindalbie Terrane, which is part of the late Archaean Eastern Goldfields Superterrane of the Yilgarn Craton of Western Australia. The area is dominated by rocks of volcanic, intrusive, volcanosedimentary origin and lesser sedimentary rocks. The local sequences have undergone tilting to sub-vertical positions and regional metamorphism to a lower greenschist facies. The principal deposits forming the known VHMS cluster are Bentley, Jaguar, Teutonic Bore and the Triumph deposit. The Jaguar Operation deposits are interpreted to have formed by subseafloor replacement, principally of shales and volcanoclastic sediments, with mineralisation located in a similar stratigraphic position near a transition from calc-alkaline to tholeiitic volcanism. The Teutonic Bore deposit originally cropped out as a gossan and is characterised by a massive sulphide lens (pyrite-sphale ........
Mining Methods

- Avoca
- Backfill
Summary:
Current (2022) mining activities are focused at the Bentley deposit.
The current mining method at Bentley is a modified Avoca method between 20m spaced levels, with long-hole open stoping in other areas.
The major modifying factors in determining the stoping inventory are:
1. A 2.5 m minimum mining width.
2. A 45° minimum footwall angle.
3. A 20 m level interval for areas without existing development.
4. A 80% stoping mining recovery for blind uphole stopes to represent the unrecoverable rib pillar material within the stope optimiser shapes.
5. A 92.5% stoping mining recovery for stopes with backfill.
6. 10-20% dilution applied depending on mining area.

Reserves at June 30, 2022:
Jaguar Operation Mineral Resource figures are reported at a AUD$100 NSR value on a block by block basis.
The estimation of the Ore reserve is based on the cut-off values of:
1. A$240 per tonne for fully costed stoping.
2. A$140 per tonne for fully incremental stoping.
3. A$80 per tonne for development.
