THARISA UNDERTAKES LONG-TERM PRODUCTION TESTS WITH LIEBHERR ON ITS ‘ROAD’ TO REDUCING
CARBON EMISSIONS

Liebherr Generation 2 Litronic Drive System Technology uses electrical energy during retarding events
and drive system technology

Tharisa, the platinum group metals (PGMs) and chrome co-producer listed on the Johannesburg and
London stock exchanges, announces that three Liebherr mining machines with more efficient engines and
fuel systems have been delivered to the Tharisa Mine and have begun operational testing. The partnership
with Liebherr is part of Tharisa’s ESG initiative to reduce its carbon footprint.

The two T 236 mining trucks with a capacity of 100 metric tonnes and one 72 ton PR 776 dozer, both of
which use the latest generation diesel engine technology with the T236s using Cummins QST 30 engines
and the PR 776 utilising the Liebherr D9512 engine, are characterised by low-level fuel consumption, and
will be fully stress-tested under operational conditions for 18 months. They will operate as part of the
production fleet under supervision of both Tharisa’s mining team and Liebherr Mining Africa.

These state-of-the-art diesel-electric mining trucks’ drive train technology benefit from improved fuel
economy due to their efficient engine and fuel system, advanced airflow system as well as low-end torque
performance and emissions capability. The trucks’ continuous drive system technology will be field tested
to determine whether the machines can withstand the climatic and geomorphological makeup of the hard
rock mining of the Bushveld Complex.

The aim of the long-term, real-life tests is to ensure the trucks reduce diesel consumption and costs while
testing the machines’ ability to deliver a minimised environmental footprint, and still delivering on
production metrics, as part of Tharisa’s drive for a more sustainable mining environment.

One of Tharisa’s core values is safety and the T236 has a variety of operational safety features such as
payload warnings, anti-rollback features, engine shutdown switches in the cab and at ground level, and
an integrated four corner park brake system. These safety systems are in line with the current
specifications of the existing truck fleet operating at the Tharisa Mine and will ensure the continued safety
and wellbeing of our staff and contractors as they work on site. The PR 776 dozer has a high-efficiency
rating of the hydrostatic drive across the entire vehicle speed range, which further minimises fuel
consumption and ensures reduced levels of carbon dioxide emissions.
Tebogo Matsimela, Head of ESG at Tharisa, commented:

“Our commitment to reducing our carbon footprint by 30% by 2030 and becoming net carbon neutral by
2050 is in action and includes using efficient technology. When we announced our targets, we already had
an action plan in place and the intention to meet, if not exceed, our 2030 target. Liebherr has been a
partner to Tharisa, and like all our other partners, we constantly challenge them to come up with
innovative, cost-saving and environmentally friendly solutions that ensure our materials, which themselves
are necessary for a more sustainable world, are produced in a sustainable manner.
Investing in the next generation of mining equipment will reduce our carbon footprint and costs, allowing
us to deliver enhanced and sustainable returns to our shareholders.”

Tharisa Mine located in the south-western limb of the Bushveld Complex, South Africa. The mechanised
mine has a 20-year open-pit life and the ability to extend operations underground by at least an additional
40 years. Tharisa also owns Salene Chrome, a development stage, low-cost, open-pit asset, located
adjacent to the Great Dyke in Zimbabwe. The Company is committed to reducing its carbon emissions by
30% by 2030 and the development of a roadmap is continuing to be net carbon neutral by 2050. Tharisa

The Liebherr T236 Litronic drive train technology uses electrical energy during retarding events and drive
system technology that delivers constant and controlled speed with efficient fuel consumption. The trucks
also have an innovative hydraulic system that lowers machine losses to provide maximum power to the
ground while lowering fuel consumption when power is not required.

The trucks come with features that provide a minimised environmental footprint and a Diesel Electric
Powertrain that significantly reduces hydrocarbon and filter usage throughout the equipment
maintenance lifecycle. The highly efficient Diesel Electric Powertrain reduces fuel consumption per tonne
moved. With the lower fuel consumption, the trucks significantly reduce the carbon footprint of the entire
operation.
