THARISA’S SKILL SET Securing highly prospective resources Robust business Proven ability model with to take projects capabilities from across the value exploration into chain production Experienced management, History of low technical and cost operation operational team Cash generation + dividends + growth = capital discipline 4

ACQUISITION OVERVIEW • Tharisa acquired 26.8% of Karo Holdings for US$4.5 million, which will be funded Karo Holdings entered into an from available cash resources Investment Project Framework • Tharisa will provide an US$8 million debt facility to Karo Holdings for initial geological Agreement with the Republic of exploration and sampling work to determine a compliant mineral resource Zimbabwe in terms of which • Tharisa will manage the exploration programme and oversee the bankable feasibility Karo Holdings has undertaken study to establish: • Access to a highly prospective area covering 23 903 hectares on the Great Dyke of Zimbabwe released by Zimplats in support of the Zimbabwean government’s efforts • a platinum group metals to enable participation by other investors in the platinum mining industry (PGMs) mine • Area estimated to contain 96 Moz (4E basis) PGMs at a projected resource grade of • concentrators and smelters 3.2 g/t 4E* • a base metal refinery • Great Dyke PGM projects are low cost, open pittable and have significant palladium • a precious metals refinery and base metal content resulting in high margin poly‐metallic revenues • power generation capacity 5

ACQUISITION RATIONALE • Improvements in the political landscape precipitated a move by Tharisa to explore geographic diversification opportunities in LARGE SCALE, A SCALABLE Zimbabwe, renowned for having the world’s largest PGM deposits LOW COST OPEN PIT outside of South Africa PRODUCTION OPERATION • Tharisa’s management team has a proven track record of developing mines from the prospecting stage through to steady- state production and this experience can be applied to the development of Karo Platinum PRODUCT • Low risk entry through Karo Holdings provides for a measured, STRONG CASH EXPANSION & staged approach to investment in Zimbabwe GENERATIVE FURTHER • Tharisa is acquiring its stake in Karo Holdings at a significant POTENTIAL GROWTH discount of more than 80% to fair value OPPORTUNITIES • The farm- in approach reduces Tharisa’s upfront exposure and creates optionality for an increased stake in the future 6
