In around March 2020, Sweetpea Petroleum Pty Ltd, a PetroHunter Energy company, took 100% ownership in exploration permits EP 136 and EP 143 after sharing a 50:50 joint venture partnership with Paltar Petroleum Pty Ltd. The permits are located in the McArthur Basin and are prospective for shale gas and conventional gas/oil. Paltar entered into voluntary administration with KPMG administrators appointed on 17 April 2019. Subsequently, Paltar and Sweetpea entered into a Sales Agreement on 12 July 2019 with the settlement coming on 6 August 2019. The transfer of interest is now complete.  The permits cover an area of 6,250 sq km and were awarded to Sweetpea in 2012. They are scheduled to expire, on 27 August 2021.  Within the McArthur Basin, Sweetpea also participates in three other surrounding permits with operator Origin Energy through a small holding in Falcon Oil & Gas Pty Ltd. In each case, Sweetpea was the original operator in the permits. Origin entered in 2014.  Sweetpea Petroleum Pty Ltd has acquired Paltar Petroleum's 50% interest in EP 136 and EP 143, within the McArthur Basin. The increase gives Sweetpea 100% ownership of the exploration permits.
