Operational Update to 30 June 2026

LONDON, 30 JULY 2026

Gemfields shareholders are advised that the Company has released information about its
operational results and financial position for the six months to 30 June 2026.

These unaudited figures have been produced on a monthly basis for Gemfields' 75%-owned
emerald mine, Kagem Mining ("Kagem") and 75%-owned ruby mine, Montepuez Ruby Mining
("MRM").

The full operational results and an excel spreadsheet of Gemfields' historic figures can be found
on the Company's website at www.gemfieldsgroup.com/operational-update/.

Highlights

    •   Total auction revenues of USD 102.9 million for the first half of the year (2025 H1: USD
        60 million)
    •   Net debt position of USD 44.2 million (before auction receivables of USD 33.3 million)
        at 30 June 2026.
    •   MRM continued to experience weak premium grade ruby recovery, at 0.025 carats per
        tonne in the six-months to 30 June 2026. The Company continues to focus mining
        activities on areas believed to contain higher-grade material, with the aim of improving
        grade outcomes. MRM's second processing plant made a meaningful contribution to
        production volumes in H1 and is expected to be signed off as fully commissioned later
        this year.
    •   Kagem maintained healthy premium emerald production during the first half, while higher
        fuel prices, exchange rate pressures and increased mining activity impacted operating costs.

Full commentary on the operational performance and financial results will be available in
Gemfields' interim results due to be published on Friday 25 September 2026.

Shareholders are advised that all figures in this operational update are unaudited, in respect of
which the directors assume full responsibility.
