I couldn't agree more. Same goes for my country. Despite being rich of these resources we often export them to be used by other countries for their product and then will be imported back here and be sold with a high rate. Once you asked why it is expensive they will tell you that it is because of the rare products used to make it, then you'll realized the said products is locally found and there are a lot of them. Typical import and export system.
Having a mineral resources doesn't guarantee that you will have the capacity to refined them to the finish products but a country who has smart politicians will not depends on exportation forever, they are supposed to sell for a particular time, generate the revenue and to improve the country and increase their target reserves so that with time, they will build one of the company to refine the natural resources for exportation and make the same money they are giving out to import this products. However, when corruption becomes the first thing politicians value the most, the country continue to borrow even with the available natural resources they have in aboundant, it crazy and pitiful to see a country suffer high rate of poverty even when they are swimming inside wealth of God gifts.
