The Aluminum Corporation of China has secured approval for a $700 million expansion at the Toromocho copper mine in Peru’s Junín region, pushing total investments by the state-owned enterprise to about $1.7 billion since 2018. According to official disclosures, the multi-year project spans 28 separate initiatives encompassing 33 operational components, designed to extend the site’s productive life to 2042 while integrating advanced molybdenum recovery to supply high-performance global alloy manufacturing.
Toromocho Expansion and Strategic Infrastructure
Toromocho generates roughly 10 percent of Peru’s total copper output. Beyond conventional mineral processing, the operation deploys autonomous drilling systems and fleet management software developed in partnership with Huawei. According to data from the Peruvian Institute of Mining Engineers, incorporating molybdenum as a commercial byproduct directly addresses surging international demand driven by electromobility, infrastructure expansion, and the energy transition, where the mineral is prized for thermal resistance.
Geopolitical Stakes and National Security Implications
Jorge Serrano, a member of the advisory team for the Peruvian Congress’s Intelligence Committee, told Diálogo that Beijing’s mining investments intertwine commercial objectives with national security considerations. Serrano noted that China targets critical minerals because materials feed directly into communications chips, nuclear energy programs, and missile manufacturing. According to research from AidData, 83 percent of official Chinese financing for critical mineral projects in low- and middle-income countries focuses strictly on copper, with capital funneled exclusively into mines where Chinese firms hold full or partial equity stakes.
Production Dominance Across Peru
U.S. Geological Survey data indicates Peru holds roughly 85 million metric tons of copper reserves, compared to China’s domestic reserves of about 41 million metric tons. With Beijing purchasing approximately 70 percent of Peru’s copper exports, Chinese-owned companies now account for roughly 30 percent of the nation’s copper production. Data through November 2025 showed that MMG Limited—a subsidiary of China Minmetals Corporation operating the Las Bambas mine—produced approximately 380,000 metric tons of fine copper, marking the first time a Chinese-owned enterprise became Peru’s largest copper producer. Combined output from Las Bambas and Toromocho has climbed more than 750 percent since 2014, establishing a supply chain that secures raw inputs directly for Chinese industrial hubs.
