Key Operating Numbers

Phoevos Pouroulis, CEO of Tharisa, commented:

"A positive start to our new financial year in what is traditionally a tough quarter with the festive season and inclement weather typically causing challenges to operations. We have made good operational improvements, with waste mining advances leading to a better mining and plant performance, resulting in record quarterly chrome production.

This performance is vital and underpins our development of the Karo Platinum Project and sets the trajectory for the coming decades at our multi-generational Tharisa Mine.

PGM prices remain subdued, negatively affecting many of the PGM miners in South Africa, once again our co-product business model continues to be operationally cash-generative, and the chrome market continues to enjoy strong demand as we enter the Chinese New Year.

This year we will be expanding and rolling out our R&D projects in distinct stages of development and commercialisation. With a solid foundation we can re-frame the operating context and re-focus our energy on our key competencies ultimately unlocking value to all stakeholders."

Health & Safety

‒     The health and safety of our stakeholders remains a core value to the Group and Tharisa continues to strive for zero harm at its operations

‒     LTIFR of

‒     0.09 per 200 000-man hours worked at Tharisa Minerals

‒     0.13 per 200 000-man hours worked at Karo Platinum

Market Update

‒     Continued strong demand was evident in the chrome market, particularly in the lead up to, these days, a less disruptive Chinese New Year period (official start date 10 February 2024), with demand underpinned by economic fundamentals and continued concerns about inland logistics in South Africa. Freight rates are ticking up on the back of geo-political events impacting maritime shipping routes

‒     The PGM market has continued to suffer from pricing pressure, however, a short-term reprieve towards the end of the quarter, driven by technical short covering, saw some price spikes. The effect of these low prices is evident on the PGM mines in South Africa, with shaft and even mine closures underway. The major pressure on PGM prices remains the (perceived) excess inventory in the PGM pipeline. We expect this to be balanced once the real demand we have seen from end users becomes evident, in particular as further supply cuts are implemented and, on a macro level, policy reduction of subsidies for EV vehicles influences demand

Operational Update

‒     Total reef mined slightly down at 1 058.6 kt (Q4 FY2023: 1 158.9 kt)

‒     Strategic ROM ore purchases supplemented own mine production with Q1 FY2024 milling at 1 424.4 kt (Q4 FY2023: 1 310.2kt)

‒     Quarterly chrome production at a record 462.8 kt (Q4 FY2023: 413.4 kt)

‒     Grade of 19.1% Cr₂O₃ (Q4 FY2023: 18.7%)

‒     Recovery at 70.3% (Q4 FY2023: 70.0%)

‒     Quarterly PGM production at 35.7 koz (Q4 FY2023: 30.7 koz)

‒     Rougher feed grade of 1.60 g/t (Q4 FY2023: 1.57 g/t)

‒     Recovery of 66.1% (Q4 FY2023: 62.7%)

Karo Platinum Update

‒     The previously announced review of the commissioning timeline of the Karo Platinum Project remains on track for first ore in mill (FOIM) for June 2025

‒     Funding solutions ring fenced to Karo Platinum are being pursued in line with the revised production timeline

Cash Balance and Debt Position

‒     Group cash on hand at US$221.5 million (30 September 2023: US$268.8 million), and debt of US$126.6 million (30 September 2023: US$142.2 million), resulting in a net cash position of US$94.9 million (30 September 2023: US$126.6 million)

It incorporates exploration, mining, processing and the beneficiation, marketing, sales, and logistics of PGMs and chrome concentrates, using innovation and technology as enablers. Its principal operating asset is the Tharisa Mine, located in the south-western limb of the Bushveld Complex, South Africa. The mine has a 13-year open pit life and is strategically advancing the vast mechanised underground resource which extends for over 60 years. Tharisa is developing the Karo Platinum Project, a low-cost, open-pit PGM asset located on the Great Dyke in Zimbabwe. The Company is committed to reducing its carbon emissions by 30% by 2030 and the development of a roadmap to become net carbon neutral by 2050. As part of this energy transition, the 40 MW solar project adjacent to the Tharisa Mine is well advanced. Redox One is accelerating the development of a proprietary iron chromium redox flow long duration battery utilising the commodities we mine.
