And now we wait

Found out in December that my sisters and I inherited my father's mineral rights, passed down from his grandfather. Seems a family member filed an AH naming everyone but my father's children as his heirs. Nice huh? A competing company found us and is working on getting us named the legal heirs. And now we wait.

So my understanding is that if you lease you get a bonus payment x your percentage of ownership. Say I own .4166 percent, negotiated 3000 per acre. That would be around a $1250 bonus. Is that the only amount I would receive until gas is actually produced from the well?
