According to an article I found [0] there are gold mines there controlled by some tribal leaders. It seems to be inhabited but not under any nation state's control.

The wikipedia page says "transient populations", actually.

It's not a land conflict. It's a territorial dispute. There's no actual conflict happening with regards to Bir Tawil.

If you had enough drilling equipment you might be able to tap into the Nubian Sandstone Aquifer. From a quick glance at some maps it seems like at least the western part of this territory might have access to it.

From the article itself

"Due to its status as de jure unclaimed territory, a number of individuals and organizations have attempted to claim Bir Tawil as a micronation. However, none have been taken seriously by the international community, and due to the remoteness and hostile climate of the region, the vast majority of these claims have been by declarations posted online from other locations."

Do you have a flag?

You're not even there!
