Reporting and standards

MMG reports its sustainability performance in alignment with recognised global standards and disclosure frameworks, including the Global Reporting Initiative (GRI), ICMM Performance Expectations, the HKEX ESG Reporting Code, HKFRS / IFRS S2, the Extractive Industries Transparency Initiative (EITI) and the Global Industry Standard for Tailings Management (GISTM).
These standards underpin MMG’s Sustainability Report, Sustainability Databook and the broader sustainability reporting suite, supporting transparent, consistent and decision‑useful disclosures.
