On May 21, MMG Limited rose 3.33% in regular trading, trading at HKD 9.29/share, with trading volume of HKD 58.11 million. The rebound was triggered by a key operational development at the company's flagship Las Bambas copper mine in Peru.

MMG's Las Bambas operation signed a memorandum of understanding with the local Challhuahuacho community, under which the community committed to avoiding blockades of the southern mining corridor — a critical route for copper concentrate and material transportation. Previous community blockades had repeatedly caused freight suspensions and even forced mine shutdowns, representing a persistent operational risk for the asset.

The agreement materially alleviates long-term logistics disruption concerns. Additionally, the stock had experienced consecutive sharp declines in preceding sessions — falling over 5% on May 18 and again on May 19 — driven by elevated US Fed rate hike expectations following stronger-than-expected US April PPI data. The combination of reduced operational risk and oversold technical conditions supported the rebound. Within the Diversified Metals and Mining sector, CMOC rose 2.21% and Wanguo Gold Group gained 6.33%, indicating broader sector recovery.
