On December 25th, Yunnan Yuntianhua (600096), a leading enterprise in the phosphorus chemical industry, announced that its subsidiary, Yunnan Yuntianhua Polyphosphorus New Material Co., Ltd. (hereinafter referred to as "Polyphosphorus"), has completed the procedures for handling the mining rights of the Zhangjia Porphyry Mine in Zhenxiong County, Yunnan Province, and officially obtained the "Real Estate Certificate of Title (Mining Right)" and the "Mining Permit" from the Yunnan Provincial Department of Natural Resources on December 23rd. This marks the official start of the development preparation phase for this massive phosphorus ore resource. According to the announcement, the mine's resource volume is as high as 24.38 billion tons, with an average grade of 22.54%, indicating exceptional resource endowment. Currently, Yunnan Yuntianhua holds a 35% stake in Polyphosphorus, and its controlling shareholder, Yunnan Yuntianhua Group, has made a clear commitment: within three years after obtaining the legal mining permit for the Zhangjia Porphyry Mine, it will prioritize transferring its 55% control interest in Polyphosphorus to the listed company. This means that Yunnan Yuntianhua is expected to fully control this giant phosphorus ore resource in the future. As China's important strategic nonmetal mineral resources, phosphorite is the lifeblood of the phosphorus chemical industry development. According to the "China Mineral Resources Report (2024)" by the Ministry of Natural Resources, China's identified phosphorite reserves reach 3.441 billion tons, ranking second globally. The Yangchang Porphyry Mine in which the Zhangjia Porphyry Mine belongs is Asia's largest known single-body rich phosphorus deposit. By the end of 2024, the cumulative proven and reviewed phosphorite resource estimate reached 4.3 billion tons, indicating the potential formation of a large-scale phosphorus resource base in northeastern Yunnan, highlighting its strategic value. Looking back, in 2024, the Yunnan Provincial Department of Natural Resources publicly listed the "Zhenxiong County Zhangjia Porphyry Mine Pilot Mining Rights" for exploration, and Polyphosphorus successfully acquired the mining rights, laying the foundation for this acquisition. Yunnan Yuntianhua stated that after the mining rights certificate is issued, Polyphosphorus will leverage its local abundant resources to build a phosphorus-based new material industrial park. It plans to fully utilize its resource, technology, and entire industrial chain advantages in the phosphorus chemical industry, promote high-value and efficient use of phosphorus resources, support the company's scale expansion and industrial structure optimization, further enhance its core competitiveness, and provide positive support for long-term sustainable development. Public records reveal that Yunnan Yuntianhua is a comprehensive chemical enterprise centered on the phosphorus industry, with business scopes covering fertilizers, phosphorite mining and processing, phosphorus chemicals, and new materials, trade logistics, etc. As of the first half of 2025, the company already owns nearly 800 million tons of phosphorite reserves, with an annual production capacity of 14.5 million tons, showing a strong industrial foundation. In terms of industry structure, affected by national environmental protection restrictions and the management of the Yangtze River, the domestic phosphorite mining and processing industry exhibits characteristics such as high industry concentration, integrated upstream and downstream levels, and stringent entry barriers. Since 2016, China's phosphorite production has gradually declined year by year, but with the rise of new energy battery materials industry, demand for phosphorite has continuously increased, leading to a recovery in production over the past few years. Currently, a tight balance between supply and demand for phosphorite has been formed, with the market price of 30% grade phosphorite maintained at around 1000 yuan per ton for over two years. The rigid demand from downstream phosphoric fertilizers and the increasing demand for lithium iron phosphate are supporting factors, maintaining a positive trend in the industry. Analysts like Guo Xin Securities have pointed out that the scarcity and irreplaceability of phosphorus minerals determine the competitive barriers in the phosphorus chemical industry. Through this investment in its subsidiary, Yunnan Yuntianhua can not only ensure a stable raw material supply for its phosphorus-based industry chain in the long term but also effectively avoid future fluctuation risks in phosphorus mineral prices, further consolidating its leading position in the domestic phosphorus chemical industry and injecting strong momentum into its long-term development.
