Originally there was a separate Mars one on EARS2, which seemed to get stuck forever, so I think after the Deep & Shallow EP was approved, they just added Mars to it, presumably to simply the whole thing for the pretty little heads of the bureaucrats - so still waiting for Mars, but the company already confirmed they had everything in place for Shallow above ground 13/8:

“The commencement of civil works follows the receipt of heritage and environmental approvals, with construction conducted with the support of heritage monitors, archaeologist and Buru supervisory personnel.
Having identified this high potential Rafael Shallow oil prospect less than four months ago, Buru is now in a position where heritage and environmental approvals are in hand, a funding agreement for the drilling of the well has been executed, the drilling rig and materials have been secured, and we have commenced well pad construction.”

but ibraz is right to point out still waiting for the PGR well approval. Doubt the rig would have been mobilized if they weren’t 100% confident of that being ticked off in a timely fashion, no reason it wouldn't be.
