Abstract: Using modern information technology, based on the integration and analysis of data from three aspects: global geology, mineral resources, and mining policies and investment environments, we can build a global mineral resources information system. This system can use multiple data sources to discover potential mineral resource-rich areas around the world, make dynamic assessments of global investment environments, and enhance geological research capabilities at global and regional scales. It is of great significance in ensuring national resource security. In recent years, based on the construction of global geological and mineral databases, we have restructured the system's architecture framework using techniques such as network resource services, data application services interfaces, spatial analysis, and web data crawlers. This has resulted in a relatively complete work process system for data retrieval, processing, management, sharing, services, and analysis at the global level. We have developed various application systems, including a global geological and mineral big data platform based on an intranet, a global geological and mineral information website based on internet services, a global mineral resources management system, a mining project investment environment evaluation system, a mining policy management system, and a strategic mineral reserves filling information system. These systems provide functions such as multi-source data correlation, remote resource sharing and retrieval, investment environment evaluation analysis, basic data collection and management, and mineral resource visualisation. They have practical significance for studying the distribution of mineral resources, analysing different mineralisation laws, evaluating the investment environment of mineral resource countries, and planning key areas for global mineral exploration and development. Ultimately, they support national energy and resource security, support bureau-level decision-making and benefit mining companies.
