cxy now possibly partnering up with enb, page-4

"For what ever reason CNX are no longer in the hunt"?

The reason is, according to CNX:

"...it has become clear that there was insufficient coal to meet Carbon Energys technical and commercial criteria for Underground Coal Gasification, as required under the Heads of Agreement."

Looking at the Xenith report, the two seams proposed for UCG average 1.29 and 2.70m thick with about 1.5m between them.

Very borderline proposition. It might be possible but seems highly unlikely CXY would trouble themselves with it.
