As a leading enterprise in the comprehensive development of salt lake resources, Zangge Mining has grown from a single potash producer into a diversified mining group with strategic presence in potash, lithium, and copper. The company was successfully listed in 2016, marking a significant step into the capital market and laying a solid foundation for its subsequent rapid growth.

Headquartered in Golmud, Qinghai Province, Zangge Mining relies on the Qarhan Salt Lake—the largest potash deposit in China—to gradually build a full-scale system covering resource exploration, development, production, and sales. Its key subsidiaries include Zangge Potash and Zangge Lithium, while also strategically investing in high-quality resources such as Mamicuo Salt Lake in Tibet and potash mines in Laos, thereby shaping a dual-track development model that integrates both domestic and international resource bases.

After more than two decades of development, Zangge Mining has established a stable supply of potassium chloride and battery-grade lithium carbonate, and holds a 30.78% equity stake in Tibet Julong Copper Co., positioning itself among the leading enterprises in China’s potash, lithium, and copper resource industries. Since its listing in 2016, the company’s total assets have increased from 7.361 billion RMB to 15.083 billion RMB in 2024, while total profits have grown from 1.087 billion RMB to 2.709 billion RMB in 2024, reflecting steady growth and strong profitability.

Currently, Zangge Mining holds 724.3493 km² of mining rights in Qarhan Salt Lake; owns equity in Tibet Julong Copper Co., with registered copper reserves of 25.88 million tons; and indirectly holds Mamicuo, Longmuco, and Jiezhe Chaka Salt Lakes in Tibet through industrial funds, with a combined lithium carbonate resource of about 6.0774 million tons. In Laos, the company owns proven potash resources of about 984 million tons across 157.72 km² in Vientiane’s Xaythany and Pakngum counties. Guided by its mission—“Continued Salt Lake Development, Leading Green Growth”—Zangge Mining drives industrial upgrading through technological innovation, with significant breakthroughs in efficient potash extraction and ultra-low concentration brine lithium extraction, forming the strategic framework of “Potash + Lithium + Copper” synergy.

Salt Lake Development, Serving National Strategy. Focusing on potash and lithium as its core business pillars, Zangge Mining has built a diversified business landscape for salt lake resource development and utilization.Potash – The Industry Cornerstone. Based on the Qarhan Salt Lake strategic resource base, the company continuously enhances resource efficiency through technological innovation. With annual potassium chloride output exceeding 1 million tons, Zangge not only helps alleviate the domestic potash supply-demand gap, but also provides strong support for China’s food security. Lithium – Extending the Growth Curve. Leveraging its technological advantages in salt lake lithium extraction, the company consistently improves production capacity and product quality, with a current annual capacity of 10,000 tons of battery-grade lithium carbonate, contributing to China’s strategic lithium reserves.

Under the Belt and Road Initiative, Zangge Mining actively expands its potash resource development in Laos, focusing on exploration and development of the Xaythany–Pakngum Salt Mines in Vientiane, covering nearly 400 km². This not only drives local economic growth but also demonstrates the strength and responsibility of Chinese enterprises in global resource development, further advancing Zangge’s “Going Global” strategy and opening up broader international markets.

Technology Innovation, Driving Industry Breakthroughs. Facing the challenges of China’s salt lake resources being “low-grade, complex, and difficult,” Zangge Mining adheres to an innovation-driven strategy and has independently developed multiple core technologies with proprietary intellectual property rights.Its “Solid-to-Liquid Transformation of Low-Grade Potash” technology has significantly improved resource utilization, enabling efficient development of low-grade resources. Its “One-Step Lithium Extraction from Ultra-Low Concentration Brine” process has broken through industry bottlenecks and greatly expanded the economic boundaries of lithium resource development.These innovations have won the Second Prize for Scientific and Technological Progress in Qinghai Province, and have been recognized by authoritative institutions as being at the international leading level, setting new technological benchmarks for the comprehensive development of China’s salt lake resources.

Practicing Green Development, Strengthening ESG Foundations. As a resource developer in the ecologically sensitive region of the Qinghai-Tibet Plateau, Zangge Mining firmly upholds the principle that “Lucid waters and lush mountains are invaluable assets.” The company regards environmental protection as its lifeline, pursuing a path of “protection within development, and development within protection.” To address historical ecological challenges in the Qarhan Salt Lake mining area, Zangge has invested special funds into comprehensive ecological restoration projects, including land leveling, subsidence backfilling, and road rehabilitation, revitalizing 145 km² of mining area. In partnership with Qinghai University, the company has launched research on the effects of ridge mulching films and nonwoven fabrics on vegetation restoration in saline-alkali soils of the Qaidam Basin, aiming to improve the ecological environment of the Qinghai-Tibet region. Through responsible practices, scientific innovation, and sustained investment, Zangge has been recognized as a National Green Mine Pilot Unit, setting a new model of synergy between resource development and ecological protection for plateau-based resource enterprises.

Empowered by Zijin Strategy, Shaping a Global Future. In early 2025, Zijin Mining invested 13.7 billion RMB to complete its strategic acquisition of a controlling stake in Zangge Mining, creating a landmark partnership in China’s mining industry. Together, the two companies will push resource boundaries and establish a dual-track development pattern of “Salt Lakes + Copper Mines.” Relying on Zijin Mining’s world-class capabilities in resource integration, capital strength, and global platform, Zangge Mining will gain robust support for the development of strategic global salt lake projects. The deep synergy of technology, resources, and management between the two companies will significantly enhance operational efficiency and provide a strategic safeguard for China’s critical mineral resource security.
