re: Ann: March Quarterly Activities and Cashf... Some update on latest 3D Seismic on the S/Hole "indicate that the western edge of the Napoleonville Dome has remained stable."

The imaging indicates that –
• There are no subterranean void spaces that could lead to the development of another sinkhole.
• There are no natural gas pockets that could continue to feed the gas that is now being vented and flared from the shallow aquifer.
• There is no evidence of multiple hydrocarbon zones to supply the sinkhole or MRAA.
• Other than the collapse zone immediately surrounding the sinkhole, the western flank of the dome is a stable formation.
• The collapse zone around Brine Cavern 3 is limited to a very localized area at a depth of approximately 800 feet and includes a small vertical riser along the outside of the salt face.
• The area of the subsurface, which was disturbed by the sinkhole, is contained within the berm, and remains far south of Highway 70.
• Hydrocarbons remaining in a portion of the “Big Hum” appear to have been liberated and have dissipated through the surrounding sediment.
