CMOC Group's stock surged 5.17% during intraday trading on Wednesday, extending its recent strong performance in the market.

The sharp rise is attributed to a significant supply chain disruption affecting the copper industry. The blockage at the Strait of Hormuz has caused a severe contraction in sulfuric acid supply from the Middle East, driving rapid price increases for this critical chemical both domestically and internationally.

This poses a major threat to copper production, as nearly 80% of sulfuric acid used in the Democratic Republic of Congo's copper smelting operations—which rely heavily on hydrometallurgical processes—is derived from sulfur imported from the Middle East. With copper mine supply already structurally tight in regions like Chile and Africa, and demand remaining stronger than expected, these multiple factors are collectively fueling upward expectations for copper prices, propelling mining equities including CMOC higher.
