based on last 10Q thought they had funds necessary based on raising 20 million - but this is apparently for future drilling needs to finish the hole and whatever processes are necessary after finishing such hole- near 3000 feet deep already is a much faster pace it seems than the last hole- and 22 inch diameter is I'm pretty sure much bigger also -wasnt last hole started at ca 8 inches? and ended with a small 4.5 inches or so

"The investment in a drilling rig capable of handling this wellbore schematic puts Zion in a much better position to meet its drilling objectives than ever before."
