We know that money from crude oil from the south goes to the center.

Please where does the money from mining solid minerals in the North go? Which body is in charge of this process?

Though I have always known that the North has abundant solid mineral which is why I am was not surprise to hear that gold is being mined in Zamfara. However, what surprises me is the fact that the process for doing this is almost hidden and not publicly available, neither does the proceeds.

Therefore, I wish to be enlightened.

The taxes go to state since they have querying tax. It also goes to federal government through ministry of mines and steel. If it's an illegal mining opperation none of that applies. Nigeria Extractive Industries Transparency Initiative has more information. NBS also publishes mining data every year aswell.

On paper it goes to the FG but in reality, it goes to individual pockets
This is the reason for the marauders invasion as it is free for all.
South, good morning!
The Oil is yours as well....

What do you mean by the above "facts" of yours. Don't make judgements from your own ignorance.

The first comment on the thread has said it all.
Just make enquires from the nearest ministry of solid minerals in your state or visit any Federal ministry of mines and steel (in your state as well)
