Mine Life2026
First copper concentrates were produced at the Kombat Mine in January 2022. Through March and April, the processing plant team completed the final upgrade of the mill.

In August 2022, a decision was made to pause operations to focus the mine plan to exclusively operate from the Kavango pit and Kombat Trend mineralization.

Summary:

The Kombat mineralised zones are carbonate-hosted base metal sulphide deposits associated with hypogene filled karst cavities and only occur along parallel “roll structures”, which are thrust-related folds. One “roll” parallel to the main Kombat Mine “roll” is present at surface at Kombat Station approximately 1,500 m to the north. The mineralised karst is thought to be caused by the upward migration of corrosive, evaporitederived brines through the Huttenberg carbonates. These brines were expelled from the basin during compression, migrated up the thrusts into folds and encountered oxidized meteoric groundwater and formed corrosive suphuric and carbonic acids. These acids were blocked by the impermeable and reducing Mulden shales resulting in the precipitation of base metal sulphides.

The orebodies are epigenetic, hydrothermal, and metasomatic replacement and fracture-fill Cu-Pb-(Ag) type deposits. Common to all types of mineralisation is the small quantity of associated hydrothermal gangue minerals such as calcite, quartz, dolomite, and seldom barite. The degree of oxidation of massive sulphides is independent of the depth, it is controlled by the proximity of the ores to the water-bearing faults and steeply foliated sandstone aquifers.

Massive and Semi-massive Sulphides are elongated, foliated zones of mineralised dolostone related to centres of tectonic and sedimentary brecciation in dolostone stratigraphy. The replacement ore is best developed in br ........


Mining Methods

Summary:

The restart of the Kombat mine is planned to take place in two phases, initially processing 30,000 tonnes per month from the open pit, following the restart of open pit mining at the end of 2021, and thereafter doubling to 60,000 tonnes per month with the restart of the underground operations. The Company is targeting copper concentrate production of approximately 1,500 tonnes per month from August 2022 from the open pit through to the end of 2023. From 2024, the company plans to mine underground to access higher grade ore. The open pit mining method that is used is conventional open pit mining with the addition of waste backfilling of the existing ore capping hole where one of the open pits is planned. Mining activities are conducted by a mining contractor who is responsible for drilling, blasting, loading and hauling. The open pit mining operations commenced in October 2021.

Reserves at August 3, 2021:
The open pit Mineral Resource is limited at depth of 160 m for Kombat and 150 m for Gross Otavi with a CuEq cut-off of 0.65% for Kombat and 0.77% for Gross Otavi. The underground Mineral Resource is below the depth limit and is declared at a CuEq cut-off of 1.5%.

Mineral Reserve estimation stated at a cut-off of 0.65% Cu.
