Assessment scope
The Sibanye-Stillwater US PGM complex includes the Stillwater and East Boulder underground mines. Stillwater started operations in 1986, East Boulder in 2001. Facilities co-located or on-site at the complex include crusher, grinder, mineral processing, tailings storage and dam, waste rock disposal, utility and transportation corridors and onsite power generation. Of the 26 chapters in the IRMA Standard for Responsible Mining, the operator suggests Chapters 2.4 Resettlement, 3.6 Artisanal and Small-Scale Mining, 4.7 Cyanide Management, and 4.8 Mercury Management do not apply. The independent audit firm will verify.
