I ask as in Aggy in one of the drier passages (my memory isn't good enough to describe where) there was a small water flow out the wall. It was all orange. Someone had placed a mug/cup on a wall directly underneath it.

Just wondered if that was ongoing dye tracing.

Can't explain the cup, but that does sound like limonite, so, yes iron minerals.
