These chests spawn randomly in various locations throughout Zek, the Scourge Wastes (Solo) and Zek, the Scourge Wastes (Heroic).

The Tracking ability can be used to locate these chests.
If your class/race can't track, consider hiring a mercenary with tracking and have him track for you.
Chests show up in track as even (white) at level 100. You can also just filter for "chest".
