Zimbabwe platinum royalty regime — what the 2023 sliding scale changed

<p>Zimbabwe holds the second-largest platinum group metals (PGM) reserve globally after South Africa, concentrated in the Great Dyke geological formation running north-south through the central Mashonaland West and Midlands provinces. Three operations — Zimplats (Implats subsidiary), Mimosa (Sibanye-Stillwater / Implats joint venture), and Unki (Anglo Platinum) — account for the bulk of Zimbabwean PGM production. The 2023 platinum royalty regime revision under Statutory Instrument 189 of 2022 substantially altered the fiscal regime under which these operations function.</p> <p>The pre-2022 royalty regime was a flat 2.5% gross-revenue royalty on platinum and PGM by-products. The 2022 revision introduced a sliding scale: 2.5% when the platinum spot price is below USD 950/oz; 5% when between 950 and 1,250; 7.5% above 1,250. The intent was to capture more rent during commodity-price upside without burdening the operations during down-cycles. The implementation additionally required up to 50% of royalty payment in physical metal rather than cash, with the metal held by Fidelity Printers and Refiners as the state agent — a Zimbabwean policy choice that has implications beyond the headline rate structure.</p> <p>The physical-metal royalty component is the part that has received less attention. The rationale, as articulated by the Ministry of Finance under Mthuli Ncube and by the Reserve Bank of Zimbabwe (RBZ) under successive governors, is that physical-metal royalty payments build state reserves of convertible assets that the RBZ can monetize on its own timing, rather than receiving cash royalty that must be immediately deployed against current spending obligations. The model has worked partially: Fidelity has accumulated some PGM stock; the RBZ has been able to use the stock as collateral for selected international short-term financing; the broader monetary-management benefit has been more limited.</p> <p>The operations&#x27; response has been mixed. Zimplats and Mimosa absorbed the royalty revision with operational continuity; their long-run mine plans and the multibillion-dollar Zimplats expansion programme through 2024–2027 have continued. The Stillwater-Sibanye Karo Resources greenfield platinum project near Mhondoro-Ngezi has, however, been substantially slowed by the post-revision regulatory uncertainty combined with the broader Zimbabwean country-risk repricing. The Anglo Platinum Unki expansion has been incremental.</p> <p>The ZEPARU (Zimbabwe Economic Policy Analysis and Research Unit) published analysis, the writing of Veronica Zano for the African Tax Administration Forum, and the work of the Zimbabwe Environmental Law Association on mining-fiscal regimes have engaged the royalty-regime question. The shared finding: the sliding-scale principle is reasonable mining-rent capture; the physical-metal component introduces operational friction without proportional state-monetary-management benefit; the overall regime tax incidence at peak prices is comparable to the South African and Botswana regimes for similar PGM operations.</p> <p>The deeper structural question is whether Zimbabwean mining-fiscal-regime design can produce the stable long-tenor investment environment that the Great Dyke&#x27;s full reserve base would justify. The PGM resource is among the largest African mineral endowments; the regulatory environment has, over the past two decades, repeatedly oscillated between accommodation (the early-2010s Zimplats expansion period) and disruption (the 2018–2019 mining-indigenization disputes, the 2022 royalty-regime revision, the periodic RBZ FX-retention-rule changes). The 2024 *re-engagement* discussions between Harare and the bilateral creditors (Paris Club, World Bank, AfDB) under the Mnangagwa government&#x27;s reform commitments would, if they produce durable results, allow the mining-fiscal regime to stabilize. The discussions have been slower than promised, and the mining-investment trajectory reflects the slowness.</p>
