You could read today's RNS to find out where the 770 came from, they have mentioned it enough!
'Significant progress achieved during the year toward drilling the Perseverance #1 well in 2020, which is targeting P(50) recoverable prospective resources of 0.77 billion barrels of oil, with an upside of 1.44 billion barrels, solely from the northern structural closure portion of the B structure. In total the B structure extends between 70 and 80 kms, has a mapped areal closure over 400 km(2) and has an aggregate most likely recoverable resource potential in excess of 2.0 billion barrels.'
