Dr David Robson, Executive Chairman and President of Tethys, commented, “It was a great pleasure to receive confirmation of the Presidential approval for the Chegara PEC from UNG, and we look forward to commencing equity production from Chegara in the nearest future, this adding another cash flow stream to the Company’s portfolio from what we believe to be a significant asset with excellent potential.”
