May I amend or change my application after I file it?

Yes. However, if your amendment adds lands, we will assign priority to those added lands from the date you filed the amended application. You must include the rental for any added lands and the processing fee for prospecting permit application amendments found in the fee schedule in §3000.12 of this chapter with your amended application.
