Sorry, I should have said third party lessee, I was going too fast.
Usually I get more than one company wanting to lease. If you have not received an offer from another company, you can try to find another lessee, shop Antero’s deal around to see if anyone will beat it. There are companies and individuals who want to invest in wells as a minority interest. Usually they find you but if not, you can try to find them. You could list your minerals under “Marketplace” at the top of this page. Give a description of where your minerals are. Right now you are a needle in the haystack and nobody will see you unless they are specifically looking for your minerals. If on the other hand someone finds your minerals are available and that they can probably be leased at a reasonable price but more than Antero’s offer, you may generate an offer.
Leasing to a third party lessee would be exactly the same process as leasing to Antero. Likely Antero would still be cutting the check for your royalty or possibly the buyer of the production, that part would be the same whether you leased to Antero or to a third party.
I would contact Antero and forward that e-mail along with the facts that you have related here including that you have other family member/owners who have not even been contacted yet. I would not include those family members’ names or addresses, let them do their own legwork if they don’t know already.
