So, the question has been raised to me again. Is it possible to have prospected a terrain with max sensors and max level in the past with negative result and then redo it later and have a positive result? My understanding is that a fail is always a fail unless come condition of the prospect has changed. Do deposit chances get reset ever? I know they were manually refreshed once long ago but do they ever do it as a normal course of events? A definitive answer on this would be much appreciated.
