In 2025, Zangge Mining continued to improve its R&D and innovation system. The Company further optimized its three-tier R&D management structure comprising the President, the Chief Engineer, and the dedicated technical R&D department. Under this structure, the dedicated technical R&D department is responsible for overall coordination and management, while relevant departments participate collaboratively. Major R&D matters are subject to tiered decision-making and management, ensuring the orderly advancement of R&D work. The Company also formulated management documents such as the Management System for the Technology R&D Department and the Intellectual Property Management System. Supported by performance assessment and reward measures for R&D personnel and a special incentive mechanism for scientific and technological innovation, the Company continued to standardize full-process management of technology R&D.
