Inner Mongolia Municipality is abundant in mineral resources such as coal, REE, non-ferrous metals, precious metals, and non-metallic minerals including chemical, metallurgical and construction materials, which provide a vita base for economic development. This paper analyzes the supply and demands of major metallic minerals and concludes that lead and zinc have a sufficient supply but need further management to avoid a surplus, that rich iron, chrome, manganese and copper have an insufficiency in supply, needing geological exploration, that gold, which was an advantageous resource, is facing a low resource guarantee level due to a rapid mining and necessitates some new discoveries, and that some abundant metals like silver and niobium need to be improved in development and utilization regardless of their high guarantee level.
