If you mean "resources" physically, I can give you an answer based on searching stuff up and reasearching. Central Asia has the largest reserves of zinc, lead, and chromite. Also, a country called "Kazakhstan" is in the top ten for supplies of copper, iron, gold, and manganese. A country called Turkmenistan also is rich in natural gas, having about 5% of all the world's natural gas. I hope this well help you out.
