The reason the pps varies is due to the SS, the stake percentage and the price of oil and natural gas. When the OS was lower the pps estimates were higher at a given market value for natural gas and oil. JMO
The pps should be in the penny range once drilling starts. The activity of the Wilcox Formation is similar to Clovelly Prospect except MXXH has a 25% stake versus 5% stake as in Clovelly Propsect. JMO
I strongly recommend you do your own D&D and review all present and past PR's issued by MXXH.
