Everyone BEWARE!!!!! There could be hidden language in your lease that
gives the company you are leasing your properity to ALL MINERAL RIGHTS TO ANY FUTURE land you may purchase. This was made aware to me by someone in the oil leasing business.
Sulphur polutes oil and gas and has to be included in the lease language. A clause should be attached to the Exhibit "A" that would read something like this "This lease is restricted to oil, gas, other liquid hydrocarbons and sulphur produced coincidentally therewith". You can get more technical with the wording if you like. Who knows what unknown substance may be under your land.
