Japan’s JBIC to finance Chilean copper mine development

Japan is enhancing its financial support for the development of copper mines in Chile, as part of efforts to increase its self-efficiency of base metals.

State-owned Japan Bank for International Co-operation (JBIC) on 25 April signed a $248mn loan agreement with Chile-based joint-venture Compania Minera Arqueros (CMAQ) to finance development of its Arqueros copper project in Chile. CMAQ is 80pc owned by Japanese copper producer Nittetsu Mining and 20pc by Chilean firm Fondo de Inversion Privado Talcuna.

The load will be co-financed by other Japanese private-sector financial firms, including Sumitomo Mitsui Banking, Mizuho Bank and MUFG Bank. The total co-funding will be $355mn.

CMAQ plans to use the funding to develop Arqueros, located 35km northeast of La Serena. The mine is expected to produce 1.8mn t/yr of crude ore and 55,000 t/yr of copper concentrates for 15 years. The company aims to start operations in 2026. Nittetsu is to secure all the output from the project.

The latest deal follows last month's loan agreement by JBIC and other financial institutes to provide $2.5bn to develop the Centinela copper mine in Chile.

Japan relies on all its copper concentrates demand from imports, which has prompted the government to secure long-term and stable supplies of copper resources. The country's strategic energy plan has a target to achieve at least an 80pc self-sufficiency for base metals, including copper, by 2030.
