Forum nazis have their own z-level in HFS.

Yeah, that is actually remarkably clever.
I think your scouting profession is a little too broad - the only other job that seems to get bogged up with that many responsibilities is masonry. But adding more geology-related jobs sounds like fun. Let's see what I can come up with:
SurveyingThere is probably a better name for it (and made this could be "geologist", though I would think that would be an over-arching name, like Farmer or Ranger). Basically your idea of predicting what sort of ore and features are around. Skill level could determine the quality/accuracy and how far through the layers predictions are made.
SpelunkingPseudo-military occupation, like hunting, that you designate to explore underground areas. Could be named better for the sake of above-ground exploration, too, depending if/how that is implemented. Possibly makes use of a climbing skill/ropes to explore otherwise unreachable levels. Should have some sort weapon, and possibly works in squads to minimize deaths. Skill level is somewhat questionable, like hunting, it is a conglomerate of talents that are applied to a certain task.
Prospecting, aka There's Gold in Them Thar HillsSometimes you have a ton useless layabouts consuming more than they produce. On maps with flowing water, but little in the way of useful resources, you could order your less talented dwarves to start panhandling in the nearest stream to pay for their keep. Silly, but could be useful for adventurers and young forts. Skill level would obviously dictate success rate/speed. Very similar to fishing.
ArchaeologyOr paleontology, not sure which is more general. It's probably mentioned in the underground diversity thread. Unearthing old, dead megabeasts would be very cool, and their could be artifacts of lost civilizations or something else. Normal miners wouldn't be careful enough to unearth these things without destroying them, and there's nothing like a masterwork plaster cast of T-Rex to compliment that dining room. It would give something fun to do with soil layers, too. Skill level should dictate recovery of certain generic artifacts, like old coins or small fossils, and higher skill would represent the rate at which they "mine" out larger fossils. Could also have another job for identifying certain recovered items - maybe that old spear you found is actually a lost artifact. Face it, dwarves would love museums.
Mineral ExtractionCould be totally period-inappropriate, but minerals and gems could be drawn from otherwise useless piles of generic stone, sort of how melting down useless metal gear gives small amounts of metal (which eventually add up to a full bar). Skill would affect recovery rates, value of minerals found, and chance to find gems.
