On April 16, Ye Jianhua, Director and Supervisor of SMM's Industry Research Department, Feng Chundi, Expert of SMM's Industry Research Institute, and Wu Tao, SMM Overseas Marketing Manager for Copper and Tin, visited Mining Mineral Resources (MMR) for a field trip and exchange, where they received a warm welcome from MMR's leadership.
During the exchange, MMR and SMM engaged in in-depth discussions on the current status of the strategic minor metal industry and cross-border supply chain cooperation. MMR has been deeply engaged in compliant mining of critical minerals for over 15 years, with a strategic focus on three key minerals — tin, tantalum, and tungsten. The company holds multiple mining licenses in mineral-rich regions of the DRC, with concentrated resource deployment and exceptional endowment. The enterprise strictly adheres to compliant mining, full-process traceability, and international operational standards, ensuring long-term stable and compliant mine operations.
SMM has long been deeply engaged in non-ferrous and rare metals, with core coverage spanning price quotations, industry surveys, and market analysis, comprehensively empowering global mineral trade and industry chain integrated services. Leveraging their respective business strengths, both parties exchanged practical experience on ex-China mineral development, compliance system building, raw material circulation coordination, and industry development trends, laying a solid foundation for subsequent industrial synergy and resource collaboration.
