First time I saw this was with geothermal in the following clip:

The snap location should be tested to make sure it can actually be built at the location and moved to the next nearest location, tested, moved if it can't place, repeat until a valid location
All this for both metal extractors of all types and geothermal of all types
The player must find a valid build location for the deposit
Play on the map LostDeadMan was playing in the video (I forget the name) and explicitly select a geothermal (probably works with any type, but Cerberus was what he was trying to build in the video). Notice that there are lots of places it can't be set.
It might be required to deform the terrain a little bit first. In which case, make a Tzar or Fatboy to ground fire around the area.
