Two Mozambique police officers killed by illegal miners at MRM
LONDON, 16 OCTOBER 2025
On Wednesday 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.
