Lease Rates for Monroe County (Bethel Township)

Does anyone know the lease bonus rates for Bethel Township in Monroe county? Or the nearby townships?

I just received on 2/27/22 an oil and gas lease offer letter on behalf of SWN Production offering $1000 per net mineral acre signing bonus or $150 flat rate for some (I’m assuming very very small) parcels we own mineral rights to in township of Adams, Monroe County, OH. Term 1 year with noise annual options to renew and 16% royalty. No details in this letter of what nma I actually own, but I called them to get more information. Am thinking this is a rock bottom offer, but have no experience with OH mineral leases. Any help including on-line map resources would be greatly appreciated. Thanks, Don
