Metallic ore resources are vital basis for industrial development and economy. Recently, as global new strategic industries develop, the industrial countries are in strong competition on metallic ore resources. This paper selects USA, a representative in industrialized country, to analyse its strategy, consumption regularity and structure over 9 decades in metallic ore resources, and finds out that since USA entered the post industrialized period non-ferrous metals like molybdenum, cobalt, tungsten and nickel showed a notable rising tendency, with strong and larger added consumption in rare and scarce metals, such as niobium, gallium, indium and zirconium concentrate, followed by tantalum, beryllium, germanium, hafnium, tellurium, selenium and rhenium. This paper presents suggestions for China's metallic ore resources development. 
