[Norfleet]

If you were playing a rich world, you may have received a random gold mine as a lucky random event: Ermor tends to have luck, and you probably did also. That would explain the province income, as Ermor's home province does not naturally receive income.

You also should never bother searching your home province in a standard game: You will never find anything. Additional sites gained in your home province are created by random events, and do not previously exist to be searched for.
