Assessment scope
Montepuez Ruby Mining Limitada (MRM) began extraction in 2013, and has been under Gemfield’s ownership since 2011. The operation employs approximately 1,500 people and covers approximately 340 square kilometers.
Approximately 12,000 people living in nine communities are potentially affected by the mine: Namanhumbir, Nanhupo A, Nanhupo B, Nanune, Chimoio, Nsewe, Mpene, Nsembia, and Wikupuri.
Facilities within the scope of the assessment include: multiple shallow open pits located in three operating blocks , concentrate storage, tailings storage, mine waste disposal, hopper, processing belt and shaking tables, maintenance and mechanics facilities, a sort house , worker housing, health facilities and security facilities, and offsite water storage and treatement facilities.
Of the 26 chapters in the IRMA Standard for Responsible Mining, the operator suggests Chapters 4.7 Cyanide Management, and 4.8 Mercury Management do not apply. The audit firm will evaluate these suggestions during desk review.
