Caledonia Mining Corporation Plc

Proposed Changes to Royalty and Tax Regimes in Zimbabwe

(NYSE AMERICAN, AIM and VFEX: CMCL)

St Helier, December 1, 2025 - Caledonia Mining Corporation Plc ("Caledonia" or "the Company") notes the proposed changes announced to the royalty and tax regimes, as they apply to gold miners, in the Republic of Zimbabwe's 2026 National Budget presented by the Minister of Finance, the Honourable Professor Mthuli Ncube, on November 27, 2025.

These include two proposed fiscal measures relevant to the gold sector: an increase in the royalty rate from 5% to 10% when the gold price exceeds US$2,500/oz (with the higher rate understood to apply to the full gold price), and a change to the tax treatment of capital expenditure whereby the current 100% upfront deduction would instead be spread over the life of the project, affecting the timing, but not the total amount, of tax payable.

The Company is assessing the implications of the proposed changes for its portfolio of assets, including in particular the potential effects on the recently announced economics of the Bilboes Gold Project.

In respect of the Caledonia group's operating mine in Zimbabwe, Blanket Mine, the change in royalty, if implemented, would be expected to result in a lower level of profitability and cash generation relative to current market expectations.

Caledonia has a long-standing operating presence in Zimbabwe and continues to engage constructively with the relevant authorities. The Company will provide a further update once more clarity is available.
