It might eventually be approved. But is there a timeframe as to how long the approval process can take?

You don't know and I don't know that either.

The approval for anything in CSG have taken extra long so far for every CSG explorers.

Look at MEL for example, Lions Way pipeline - submission December 2010, was asked for "Additional information" a few months later. Richmond Valley Power Station - approved around July 2010 but still waiting for production license.

This Government is in no hurry at the moment. Don't get your hopes up.
