A recent High Court ruling in favour of Zimbabwe Platinum Mines (Zimplats) has reinforced the role of Zimbabwe’s courts in defining the limits of mining taxation, even as disputes between miners and the Zimbabwe Revenue Authority (ZIMRA) continue to surface across the sector, Mining Zimbabwe reports.

This follows a recent High Court ruling that the country’s number one platinum group metals (PGM) producer, Zimplats, is not liable for US$7.1 million in mining royalties on matte and concentrate exported between June 2018 and December 2021.
At the centre of the dispute was whether the Finance Act, as it stood before amendments that took effect on January 1, 2022, allowed ZIMRA to levy royalties on intermediate or mineral-bearing products.
The High Court found that royalty rates during that period applied only to “minerals,” not to matte or concentrate. With no legally fixed rate, no lawful obligation could arise. ZIMRA’s assessed shortfalls and penalties were effectively set aside.
The ruling goes beyond immediate financial relief. By applying the law strictly as it stood, the court reaffirmed a core principle: taxes and royalties must be grounded in clear statutory authority.
This mirrors earlier decisions, such as the Supreme Court’s ruling in favour of ZIMASCO, which blocked a US$7 million ZIMRA claim on chrome concentrates and ferrochrome produced before 2022. The court held that mineral-bearing products without prescribed rates cannot attract royalties.
Taken together, these rulings have boosted investor confidence. They show that Zimbabwe’s courts can resolve complex fiscal disputes predictably. In a sector long challenged by policy uncertainty, the judgments signal that legal clarity can exist alongside administrative oversight.
Yet, outcomes are not uniform. Afrochine Smelting, another ferrochrome producer, lost a High Court challenge after ZIMRA’s assessment was upheld. These contrasting results highlight that product classification and transaction specifics remain crucial.
Even with court clarity on historical royalties, taxation challenges persist. Industry bodies warn that uncertainty remains, especially in platinum group metals (PGMs) and lithium.
The Chamber of Mines of Zimbabwe reports that PGM producers face ongoing export tax demands on concentrates and matte.
This comes despite an agreed phased beneficiation roadmap. Investments in domestic smelting have created excess capacity, allowing toll treatment of third-party material from mid-2025.
All PGM concentrates are expected to be processed locally by 2026.
Lithium producers are also raising concerns.
They say ZIMRA is levying royalties based on lithium carbonate prices while collecting beneficiation tax on concentrates.
Since VAT already recognises that spodumene, petalite, and lepidolite are exported, the dual tax amounts to double taxation.
Producers are calling for royalties to be based on actual concentrates or for the beneficiation tax to be removed when lithium carbonate pricing is applied.
Viewed together, the Zimplats ruling, earlier court decisions, and ongoing industry submissions reveal a structural challenge.
While courts have curbed retrospective claims, disputes over export taxes, beneficiation levies, and royalty valuation persist.
Without a clarified and consistently applied fiscal framework, friction between miners and ZIMRA is likely to continue.
For a sector expected to anchor Zimbabwe’s long-term economic growth, the message is clear: predictable taxation and legal certainty are now as critical to investment as the country’s mineral endowment itself.
