‒     Successful first blast at the Tharisa Mine Apollo portal marking the official transition to underground mining in parallel with the existing open cast mining operations

‒     PGM prices averaging at US$3 038/oz (Q1 FY2026: US$2 208)

‒     Quarterly chrome production of 404.0 kt (Q1 FY2026: 349.4 kt) with chrome recoveries stable at 69.7% (Q1 FY2026: 70.3%)

‒     Average metallurgical grade chrome concentrate price at US$290/t (Q1 FY2026: US$276/t)

‒     Group cash on hand of US$184.3 million (31 December 2025: US$122.2 million), and debt of US$129.6 million (31 December 2025: US$75.2 million), resulting in a net cash position of US$54.7 million (31 December 2025: US$47.0 million)

Phoevos Pouroulis, CEO of Tharisa, commented:

"This quarter's results reflect the resilience and operational discipline that define Tharisa, underpinned by our continued strong safety performance, in traditionally the toughest operational quarter, impacted by increased lightning events and high rainfall. We nevertheless increased quarterly output in the chrome segment, while PGM output was hampered by lower grades in the reef being mined.

While reef mined was lower in the quarter due to in-pit constraints, processing throughput remained strong with improved chrome feed grades supporting higher chrome concentrate production. PGM production was impacted by lower grades in the reef being mined, although recoveries remained robust. On the processing side, PGM recoveries of 77.5% and chrome recoveries of 69.7% demonstrate the consistency of our operations.

The pricing environment strengthened materially during the quarter, with the average PGM contained metal basket price increasing to US$3 038/oz from US$2 208/oz in Q1 FY2026, while the average metallurgical grade chrome concentrate contract price improved to US$290/t from US$276/t in
Q1 FY2026. Current chrome prices at approximately US$315/t  are supported by higher logistics and freight costs due to the increase in global oil prices. In light of the current geo-political challenges, we have put in place mitigation measures to ensure, as far as possible, security of fuel supply to the Tharisa Mine, while costs will increase, our focus remains on efficiency.

The official commencement of the underground development at the Tharisa Mine took place on
31 March 2026 with the first blast at the Apollo portal. This development showcases the long-term life of the Tharisa Mine, with over 60 years of underground mining potential, while we will be investing over US$500m over the next decade to sustain the optimal output of over 200 kozpa of PGMs and
2.0 Mt of chrome concentrate. The underground development is a natural progression for the Tharisa Mine and forms a core pillar of Tharisa's long-term strategic vision and capital allocation.

We continue to make good progress in further derisking our Karo Platinum project in Zimbabwe, with open pit surface clearing commencing as planned, following the successful mobilisation of our mining contractor at the end of the last quarter. Infrastructure development and investment in key work packages continues securing  the necessary power, water and long lead requirements. Good progress has been made in terms of the Karo funding, which, will provide the full requirements for project completion and targeting first ore in mill in H2 2027. The funding is subject to final agreement with the Government of Zimbabwe on the fiscal stability agreements which are nearing conclusion.

These results reinforce our confidence in the Group's strategy, our balance sheet discipline and our ability to continue delivering long-term value. I thank our teams for their continued dedication to safe, efficient and responsible production and project development."

Health & Safety

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

‒     Lost Time Injury Frequency Rate ('LTIFR') per 200 000 man hours worked of

‒     0.03 at Tharisa Minerals

‒     0.00 at Karo Platinum

Market Update

‒     Platinum fundamentals remain firm as the market comes to terms with the deficits in the supply demand dynamics, with the de-stocking of inventory pipelines, any new demand will need to be met by new supply. Prices held firm even during the disruptive geopolitical second half of the quarter. Chrome prices remain strong with logistics costs being passed on to the end customer. 

Operational Update

‒     Reef mined at 872.4 kt (Q1 FY2026: 1 239.0 kt)

‒     Strip ratio increased disproportionally due to lower mining rate

‒     Reef milled at 1 387.9 kt (Q1 FY2026: 1 361.5 kt)

‒     Quarterly PGM production at 34.3 koz (Q1 FY2026: 38.8 koz)

‒     Rougher feed grade of 1.29 g/t (Q1 FY2026: 1.41 g/t)

‒     Recovery of 77.5% (Q1 FY2026: 78.8%)

‒     Quarterly chrome production of 404.0 kt (Q1 FY2026: 349.4 kt)

‒     Grade of 16.9% Cr₂O₃ (Q1 FY2026: 14.9%)

‒     Recovery at 69.7% (Q1 FY2026: 70.3%)

Cash Balance and Debt Position

‒     Group cash on hand of US$184.3 million (31 December 2025: US$122.2 million), and debt of US$129.6 million (31 December 2025: US$75.2 million), resulting in a net cash position of US$54.7 million (31 December 2025: US$47.0 million). The increase in cash on hand was partly offset by higher debt, reflecting funding drawdowns for the underground development and working capital timing during the quarter.

Guidance

‒     Production guidance for FY2026 is set at between 145 koz and 165 koz PGMs (6E basis) and 1.50 Mt to 1.65 Mt of chrome concentrates.

The above forward-looking statements have not been reported on or reviewed by Tharisa's auditors and is the responsibility of the directors.

Development of the Karo Platinum Project, a tier-one PGM project on Zimbabwe's Great Dyke, further reinforces Tharisa's growth strategy. Investments in downstream beneficiation, including proven chrome and PGM alloy production, will add significant value when commercialised. Tharisa is committed to reducing carbon emissions by 30% by 2030 and the sustainability roadmap targets net carbon neutrality by 2050. Through Redox One, Tharisa is advancing proprietary iron-chromium redox flow battery technology, utilising the very commodities it mines to support long-duration energy storage - a key component in the transition to renewable energy.
