Update on incident in Mozambique

LONDON, 16 OCTOBER 2025

On Monday 15 October 2025, a group of approximately 40 illegal miners marched on the mine gate at
Montepuez Ruby Mining ("MRM"). They proceeded to attack Mozambican police officers present at the
gate, killing two, one of whom was a commander of Mozambique's Natural Resources Protection Force.

No MRM employees or contractors were injured in the attack and onsite conditions have been calm since.

MRM has been informed that the attack may be related to district immigration authorities investigating,
earlier in the day, suspected illegal immigrants in a local village and during which it is reported that an
individual died.

As previously disclosed, in recent weeks, the operation of MRM's new processing plant, in the final
commissioning process, has been impacted by illegal miners sabotaging the plant supply infrastructure.

Gemfields and MRM continue to engage with the appropriate Mozambican governmental authorities and
remains committed to the safety and security of its employees, contractors and host communities.

Gemfields funds projects to improve health, education and livelihoods for communities around its mines,
supports local conservation partners and created the Gemfields Foundation, its charitable arm, which
magnifies the scale of the work already carried out by Gemfields itself.

Gemfields values transparency, legitimacy and integrity, and believes that coloured gemstones should create
a positive impact for the countries and communities from which they originate.
