Metal ores are likely to be found in plenty near subduction zones where volcanic activity has occurred in the past.
Explanation:
Metal ores are generally formed out of volcanic eruptions. The molten magma that comes out of the Earth's crust in the form of lava contains ferrous and sulfide minerals.
When the lava is rapidly cooled down under the ocean, the ferrous and sulfide minerals don't amalgamate properly with the rocks and result in the formation of metal ores.
