We have been notified of mineral rights our father owned and been passed to the children. This company has offered $100.00 signing bonus. Also, a 4.5% royalty when coal is mined…This 4.5% will be paid MINUS…all chgs assessed by purchaser, taxes due to production, sales and a whole list of expenses, and Transportation costs…this seems strange to me. We are not in coal business…why should we pay for all this out of 4.5%??? It may be normal…just needing advice from someone who knows… Also…even though it is only… .59 of an acre, I still do not want to be taken advantage of. 2 siblings already jumped at signing for 100.00 Just don’t like to jump this fast without information… Thank you all for your time and consideration in this matter. I appreciate your help!!!
