(IMPORTANT: This object aggroes on any players who come too close, despite being Hidden or Invisible and explodes after a short while. If that happens, the group of nearby Scrapyarders will aggro on the player as well, so don't get too close if you are ghosting the mission!)
Stolen explosives appear on the mission Catch Agent Sampson from Operative Vargas.

These explosives are highly unstable.
This is what the nearby Scrapyarders say when the item is found:

Scrapyarder miner 2: As long as some villanous maniac doesen't come along and blow them up.
Scrapyarder miner 1: Don't letnear the explosives!
