Central Petroleum Limited (ASX:CTP) (FRA:C9J) (OTCMKTS:CNPTF) advised that after consultation with Georgina Energy Plc (Georgina), the recently announced sale of Central's interest in several sub-salt exploration permits in the Northern Territory has been amended to exclude EP82 (containing Magee/Mahler) resulting in Central retaining ownership of subsidiary, Helium Australia Pty Ltd ("Helium").

EP82 is one of three sub-salt exploration permits in the Northern Territory's Amadeus Basin which are subject to a conditional sale and purchase agreement announced on 12 November 2025. The Magee/Mahler prospects are believed to be much smaller and less commercial than the other subsalt prospects being targeted for helium the basin.

The exclusion of EP82 will allow Georgina to focus more resources to the two other permits being transferred, EP112 (Dukas) and EP125 (Mt Kitty), along with their other primary targets in the Amadeus and Officer Basins which have larger target prospective / contingent resources of helium, hydrogen and hydrocarbons Central has also provided notice of Helium's withdrawal from the EP82 Joint Venture with Santos.

The other terms of the Georgina sale transaction remain unchanged.

It is expected that Central will recognise an impairment charge of $4.2 million in its FY26 financial statements as a result of the withdrawal of its interest in the EP82 Joint Venture.
