There is talk about finding lithium in the Nacogdoches area. If so…
Should we amend the lease agreement if it doesn’t include lithium in the waste removal terms?
A little Googling reveals that it’s more involved than adding a singular clause. See " The Lithium “Boom” in Northeast Texas" at the Texas Oil and Gas Attorney Blog
You need very specific language in your lease for lithium. Please use a good oil and gas attorney for help or it will not be done correctly.
Also, if you already have an active lease, it will probably not be possible to amend the current lease. The lithium must be claimed (if possible) before drilling.
The correct language will vary from state to state depending upon statute.
