On May 28, JX Advanced Metals, Mitsubishi Materials (MMC), Mitsui Kinzoku, and Marubeni signed a final agreement to integrate MMC’s copper concentrate procurement and sales of cathode copper, sulfuric acid, and other by-products into Pan Pacific Copper (PPC), while establishing a wholly-owned subsidiary, "PPC Material." The integration will be executed via a company split: PPC first absorbs the target business, then transfers it to the newly established PPC Material on the same day. Originally planned for end-March, the process was delayed by about two months due to detailed discussions. Post-integration, PPC’s ownership stands at: JX 32.50%, MMC 32.00%, Mitsui Kinzoku 21.90%, and Marubeni 13.60%. PPC becomes an equity-method affiliate of all four companies, with PPC Material as its wholly-owned subsidiary. Currently, PPC subcontracts smelting/refining to JX Metal Smelting and Hibi Smelting; after the deal, MMC will also become a subcontractor. Japan’s copper concentrate procurement windows will shrink from three to two, held by Sumitomo Metal Mining and PPC Material. The move aims to counter intensifying overseas competition and sharply deteriorated TC/RC through centralized procurement and cost efficiency. The transaction is planned for October 1, 2026, pending regulatory approvals.

Australia’s New South Wales state has officially approved RZ Resources’ A$693 million ($497 million) Copi mineral sands mine project. Located 75 km northwest of Wentworth, the mine holds one of the world's largest critical minerals deposits and is expected to produce up to 400,000 tonnes of critical mineral ore annually—including titanium minerals, premium zircon, and rare earth elements—for an 18-year lifespan. Backed by governments including the US, Japan, India, and Australia, and featuring strategic investments from Japan’s JX Advanced Metals Corporation and Marubeni, the approval clears a pathway to first production in early 2029.

Based on calculations derived from the production plans of major smelters, Japan's copper cathode production in H1 of fiscal year 2026/27 is expected to grow 3.3% YoY, driven by firm demand for copper alloy products and copper wire in the power sector.H1 of the fiscal year runs from April to September.A spokesperson for Pan Pacific Copper (PPC), Japan's largest copper supplier, said the company's copper cathode production in H1 is expected to rise 7.5% YoY, as the operating rate at smelters under JX Advanced Metals is expected to improve.

As semiconductor demand surged, JX Advanced Metals Corporation, Japan’s semiconductor materials giant (JX Advanced Metals Corp., hereinafter referred to as JX Advanced Metals), plans to increase investment in chip and information technology materials. President Yoichi Hayashi said the company plans to invest about 100 billion yen ($623 million) annually across all business divisions, with a focus on chip-related businesses. Over the past three years, the company invested an average of 90 billion yen per year. JX Advanced Metals is one of the beneficiaries of the rapid buildout of AI data centers, and its clients include global chipmakers such as TSMC, SK Hynix, and Intel. This has prompted the company to shift from its traditional copper smelting business to chip and information technology materials. In an interview, Hayashi said, “I do not think we should blindly expand investment, but it would be a serious mistake to hesitate when there are clear opportunities. I believe now is the time for us to take certain risks.” As demand exceeded expectations, JX Advanced Metals raised its operating profit forecast for the fiscal year ending March 31 by 20. Sales of indium phosphide, a semiconductor material produced by the company, were strong, and the company said it will make additional investment to expand capacity. Hayashi said that, given tight supply and demand, the company was negotiating with clients to raise product prices. He added that the magnitude of the price increases varied by product, but did not disclose specific details. He believes the war in the Middle East will not have a significant impact on the company’s operations, but is monitoring developments closely. JX aims to achieve operating profit of 200 billion yen in growth segments, including its chip materials business, by the fiscal year ending March 2040. Operating profit for the most recent fiscal year was about 52 billion yen. (Wenhua Composite)
