Phoevos Pouroulis, CEO of Tharisa, commented:
“The fourth quarter of our financial year delivered the highest production of PGMs and chrome
concentrates in the history of the Tharisa Mine. This performance follows several strategic initiatives to
optimise the operation, these have built a sustainable platform for Tharisa to deliver further significant
growth over the long life of our open pit operations.

The continued improved performance over the past twelve months was achieved through the proficiency,
commitment and focus of all our staff, who not only delivered our results safely, but did so in the face of
COVID-19 uncertainty, which saw thousands of man hours lost during the past 12 months. The challenge
of the pandemic persists on numerous fronts, yet we remain confident that the measures we have taken
in the last two years will continue to allow us to overcome these and future challenges.

With the FY2022 production guidance provided for the Tharisa Mine, we see further growth particularly
from the investment made in the Vulcan plant, which is in the cold commissioning phase and will produce
chrome concentrates before the end of 2021. In Zimbabwe, the exciting developments with Salene Chrome,
in the construction phase, as well as the progress on the development of Karo Platinum, will contribute to
Tharisa’s growth trajectory over the next two years.

As we enter the next phase of the development of our business, Tharisa remains a key participant in the
global transition to a low carbon economy through the critical metals we produce. Not only will Tharisa
contribute to this transition, we will deliver on our stated goals of reaching 30% reduction in emissions by
2030 and carbon neutrality by 2050 through the extraordinary skills and initiatives of our own research
and development team as well as the adoption of leading technologies.”

Health & Safety
   -   The health and safety of our stakeholders remains a core value to the Company and Tharisa
       continues to strive for zero harm at its operations
   -   LTIFR of 0.34 per 200 000-man hours worked
   -   Tharisa recorded its fifth-year fatality free, a testament to the due diligence and focus of our staff
   -   South Africa is at an adjusted Alert Level 1 as the country has exited Wave 3
   -   The Company currently has zero active COVID-19 cases

Market Update
   -   While the PGM basket price increased by over 80% on an annual basis, this was somewhat
       dampened by the softer PGM basket price in the last quarter, which saw the average basket price
       reduce by 25% QoQ. While the upside price movement may be perceived to have overrun, short
       term supply-demand disruptions need to be countered by the strong fundamentals of PGMs in
       the longer term, driven by a healthy outlook for the internal combustion engine, investment and
       industrial demand. While substitution will take place between palladium and platinum in catalytic
       converters over time, the inability to substitute the minor metals, the largest of which is rhodium,
       ensures that the PGM basket price will remain robust for at least the next 5-year period

   -   Chrome prices improved in the last quarter with an increase of over 4% compared to the June
       2021 quarter, and also saw an increase of 10% on an annual basis, with spot trading at US$165/t.
       Prices will need to remain at these levels for most producers to remain profitable and continue to
       invest, as shipping rates have dented margins, with the global logistic industries continuing to be
       impacted by the pandemic and challenges with supply chain management. Despite some output
       cuts at stainless steel plants in China, output is nevertheless expected to increase close to double
       digit percentage growth compared to 2020 as both domestic demand and export demand drives
       higher output levels in China. South African inland logistics issues have led to longer supply chains
       and thus increased pricing for products, while stockpiles of chrome at port level in China remain

Operational Update
   -   Total reef mined slightly down QoQ but up over 8% YoY to 5.4 Mt
   -   Annual stripping ratio of 11.6 m3: m3 ahead of LOM requirements
   -   Tonnes milled increased QoQ leading to an increase in milled tonnes for the year of over 11% to
       5.6 Mt
   -   Record quarterly PGM production at 43.7 koz leading to an annual output of 157.8 koz, within
   -   Record quarterly chrome output of 395.7 kt leading to an increase YoY of 12% in chrome output
       to 1 506.1 kt, within guidance
   -   The improvements in PGM grade to 1.59 g/t are as a direct result of the mining efficiencies
       achieved in the last 18 months, allowing the mine to focus on ‘right mining’ to achieve the optimal
       grade mix
   -   Correct grade mix has resulted in the plants running optimally, leading to improved recoveries
   -   The mine has approximately 2-months ROM stockpile ahead of the plants

Zimbabwe update
   -   Salene Chrome is on track to commence production in Q1 FY2022
   -   Salene Chrome mining has commenced, and the metallurgical plant construction is in progress
   -   Karo Platinum implementation studies completed

Cash Balance and Debt Position
   -   Tharisa had a cash balance of US$83.4 million (30 June 2021 US$80.5 million) at the end of the
       quarter and debt of US$35.5 million (30 June 2021 US$38.7 million) resulting in a positive net cash
       position of US$47.9 million (30 June 2021 US$41.8 million), with a significant portion of capital
       spent on the construction of the Vulcan plant being internally funded
   -   The Company’s strong balance sheet with low leverage positions it to fund its growth aspirations
