The Responsible Minerals Initiative (RMI) released Additional Minerals Reporting Template (AMRT) version 1.31 on April 17, 2026 as part of a coordinated update to its responsible minerals reporting templates (alongside CMRT 6.6 and EMRT 2.11). AMRT 1.31 delivers updates to support reporting of additional critical minerals beyond those covered by CMRT and EMRT, improving data consistency, validation, and alignment with global critical-minerals regulations and sustainability initiatives. Compliance teams using AMRT for extended due-diligence data collection should adopt v1.31 in their next supplier-survey cycle and update version-control statements accordingly.
