Manchuria was valuable during the imperialistic age and today, albeit less so, because it is rich in deposits of metal ore.
Metal-bearing rocks sought after in mining are typically called ore deposits. These deposits contain high enough concentrations of valuable metals such as copper, gold, silver, or iron to be economically viable for extraction. Mining companies prospect for ore deposits to extract and process the valuable metals.
William Seward
Ores are deposits of economically valuable minerals, usually - but not necessarily metallic minerals.
That would be referred to as a vein, or if a valuable mineral, an ore vein.
