A YEAR OF INNOVATIVE PROGRESS IN THE FACE OF EXTERNAL ENERGY UNCERTAINTY

When I wrote to you this time last year, the first time as chair of our newly formed Climate Change and Sustainability Committee, I was conscious of the potential unpredictability of the pathway to addressing climate change. I was nevertheless still surprised at the magnitude of the impact of global events that have occurred in the last 12 months on energy security, global supply chains and our business. Our business has shown remarkable resilience over the past year, which has made us focus even more on improving its sustainability and playing our part by delivering the critical metals necessary for a cleaner future as well as decarbonising our own activities.

As a business, we are acutely aware of the role we play in the broader society and we need to act with integrity and transparency in everything we do. At Tharisa we have a culture of continuous improvement across all of our operations and activities. This committee, together with its sister committees, the SHE Committee and Risk Committee, ensure we have a comprehensive view of all our activities, particularly those that will deliver our goal to be net carbon neutral by 2050.

The most vital component of our focus this year has been energy security. We have partnered with Total Eren, a leading independent power producer, and Chariot Limited, an African-focused transitional energy group, to develop a solar energy solution for our operations and are, by now, well advanced not only in the technical aspects but have applied for the various permits, including environmental, which we expect to be granted during the second quarter of 2023. In addition to the development of the solar power generation, we also see energy storage as a vital component of our sustainability strategy. To this end, our Research and Development division has been innovating technology in several areas. Not only have we been continuing to maximise our minerals recovery from our mining operations, but Arxo Metals is also actively researching battery technology solutions utilising our own mineral products. We expect to develop our energy storage business over the years to come which will greatly assist our decarbonisation efforts and make our business part of the circular economy.

We have made CONSIDERABLE PROGRESS IN THIS ASPIRATION, not only in relative, proportionate terms for a company of our size and footprint but also in absolute terms. We recognise that the journey has just started and that we can expect to enhance and modify our plans along the way.

As a primary extractor of minerals, we are acutely aware of the complexity of navigating economic and market uncertainty. However, we believe that our sustainability plans will enable us to navigate these challenges and continue to deliver resilient growth and returns in uncertain times.

As a mining company, our imprint on the environment is obvious and we are committed to operating responsibly and minimising lasting impact. Indeed, our license to operate depends on this. We are also conscious of the need to sustain responsible supply chains and are working continuously to improve in this area. Investors and financiers are concentrating heavily on this subject and we believe that Tharisa will be viewed as a responsible supplier of its products which will enable it to access the widest range of capital to finance and grow its business.

I wrote last year about how we need to mitigate the potentially adverse impacts of mining on the environment and ensure that our values on sustainability and mitigating climate change are reflected throughout our value chain. We have made strides in this area and our ESG team is rolling out the standards we have adopted at Tharisa Minerals across the Group, particularly in Zimbabwe on the Karo project. The Committee believes we have set ourselves achievable and realistic goals aimed at reducing our carbon emissions. We will achieve a 30% reduction by 2030 (from a 2020 financial year baseline that uses 2019 data) and our roadmap to be net carbon neutral by 2050 is in place.

Against this background, our disclosure is intended to enable all stakeholders to understand our strong commitment to sustainability and addressing climate risk. Our goal is to provide relevant information to our stakeholders and to improve this continuously over time as our plans become operationalised. We are conscious that corporate disclosures in this area are in their early stages of development and will ensure that the information we disclose is accurate and carries an appropriate level of assurance. To this end, we have started working with external assurance providers in the environmental area and continue to align our business with global reporting standards.

Thank you for your interest in the work of this Committee. The Tharisa executive team has worked hard over the past year to innovate and deliver a cleaner future for the company and we are confident that we are on the right path and excited about the creative ideas coming from our teams to assist delivery.
