Mineral Resources

Business Overview

Japan is highly dependent on imports for most of the non-ferrous metal resources including copper due to its scarcity of natural resources. Although copper is an indispensable metal resource in modern society, it's more difficult than ever to secure copper ores constantly due to its uneven distribution, a country risk, a price/exchange fluctuation risk, larger scale of mine development projects and soaring development costs due to intensifying global competition to acquire resources. Moreover, the demand of high-grade clean copper concentrates is increasing in the global trend of decreasing copper concentrate grade and increasing its impurity level. In such environment, we are seeking to maintain the stable operation and improve productivity of the Caserones copper mine.
We are also actively engaging in exploration and research of minor metal mines, which could contribute to a growing demand in the field of advanced materials in the future.

Caserones Copper Mine

In Chile, South America, The Caserones Copper Mine has started the production of copper cathodes by SX-EW since 2013, and also has started the production of copper concentrates since 2014. Its copper concentrates are clean with low impurities and leading raw materials for the JX Advanced Metals Group's smelters, playing an extremely important role in our copper smelting business, which is the core of the supply chain of metals.

Caserones Copper Mine: History of Development

May 2006 Pan Pacific Copper Co., Ltd. (in the JX Advanced Metals Corporation Group) acquired mining rights to the Caserones Copper Deposit (then called the Regalito Copper Deposit).
- Economic feasibility was assessed based on drilling surveys and other studies.
September 2008 Feasibility studies were begun.
2010 The decision was made to go ahead with development. Construction was begun.
March 2013 Refined copper production by the SX-EW method was begun.
May 2014 Copper concentrates production was begun.
July 2014 The first shipment of copper concentrates departed, bound for Saganoseki Smelter & Refinery of Pan Pacific Copper.
A mine opening ceremony was held.
February 2021 The JX Advanced Metals Corporation have acquired Full Rights and Interests.
July 2023 JX Advanced Metals Corporation transfered 51% of interests to Lundin Mining Corporation.

Other mining investments

In addition to the Caserones Copper Mine, we own interests in other promising mines overseas, seeking not only return on investment but also a stable supply of copper ores. These are large-scale mines in the global top 10 in the copper production volume, and, like Caserones, are located in Chile.

Worldwide distribution of copper mines

A major feature of non-ferrous metal deposits is that they are unevenly distributed in specific locations. In terms of copper resources, South America accounts for nearly half of the world's copper production, with many deposits distributed in Chile.
