How to get a mortgage lender to understand income from an oil lease

I hope someone has encountered this situation and can point me in a direction that can help my home mortgage lender to understand an oil lease. The situation is that Ninepoint Energy is now going to be Bowline Energy. My lender wants me to provide a current or updated lease with the Bowline . I explained the lease passes to the new owner intact. They demanded I sign a request for any and all updates on my lease. I signed it and then I explained it often takes weeks to get a reply. Even for a voicemail. The verbiage on the original lease is very clear that it’s ‘forever’. I don’t have weeks to wait for an oil company to answer a request for something they know I already have and, in fact, the request may confuse them since there aren’t ‘updates’. Has anyone else encountered a similar issue and had a simple resolution for it? My rate lock is going to expire in less than two weeks. It’s a California lender who’s probably not had an applicant use royalty income as primary income and thus has absolutely no understanding ( even though I explained it in myriad different ways).
