Jaguar Operations is an established underground zinc, copper, gold and silver mining operation. Operations include an underground mine at the Bentley deposit utilising open stoping methods and a processing plant producing copper and zinc concentrates with precious metals by-products. Concentrates are trucked to the Geraldton for export to customers internationally.
On 2 August 2023, Aeris announced that it would be placing the Jaguar Zinc/Copper Operations (Jaguar) on care and maintenance in September 2023, due to forecast operating losses in FY2024. The Company will immediately commence feasibility work on restart options for the operation, incorporating other known resources on the tenements. |

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 ........
Mining Methods
- Longhole open stoping
- Longhole stoping
- Avoca
- Backfill
Summary:
Mining activities in 2023 were focused at the Bentley deposit.
The mining method at Bentley deposit is a modified Avoca method between 20m spaced levels, with long-hole open stoping in other areas.
The planned mining method for Bentley Deposit is longhole stoping with rock based backfill. This is the same as was used at the operation.
In 2023, over the last two quarters, the mine experienced three separate mining induced seismic events, which delayed production and required a cessation of operations in the high-grade Bentayga mining area.
Production was also impacted by low development rates caused by congestion in the lower levels of the mine and limited ventilation.
Post year end, the decision was made to suspend production and place Jaguar Operations on care and maintenance in September 2023.
The decision preserves the in-ground value of the significant resources identified across the Jaguar tenements. In FY2024 Aeris will undertake a feasibility study on options to restart Jaguar at higher throughput rates by incorporating other known resources on the tenements.
