Announcement PDF ASX Announcement 22 April 2025 ASX:TEG Becos-1 Well Drilling Results The Becos-1 well has reached a Total Depth of 1,107m measured depth (MD) The well failed to prove hydrocarbons in economic quantities and has been plugged and abandoned Triangle Energy (Global) Ltd (ASX:TEG) advises that the Becos-1 exploration well in the Perth Basin reached TD of 1107m (MD) in the early hours of Friday, 18 April 2025 after which electric logs were run, with analysis performed over Saturday and Sunday. Unfortunately, the well only encountered gas in a 2m low porosity High Cliff sand (943 to 945m MD), which was calculated to be immoveable, and had low grade gas shows in the Bookara sandstone. Consequently, the well has been plugged and abandoned. Becos-1 was drilled by the EP 437 Joint Venture, comprising subsidiaries of Triangle as Operator 50%, Strike Energy Ltd (ASX:STX) 25% and Echelon Resources Ltd (ASX:ECH) 25%. Key information about the well is shown in Table 1 below.

Significant prospectivity remains in our north Perth Basin permits in a number of different plays and as yet untested areas.” “Despite the result of Becos-1, Triangle continues to be well placed and funded to carry out future exploration and new ventures projects, with a healthy cash balance and up to $18 million to be received for the sale of the Cliff Head Assets.” Authorised for Release by: The Board of Directors ENDS triangleenergy.com.au Triangle Energy (Global) Limited ABN 52 110 411 428 Suite 2, 100 Havelock St, West Perth WA 6005 | PO Box 51 West Perth WA 6872 Australia T +61 8 9219 7111 For more information Mr Conrad Todd Managing Director E: ctodd@triangleenergy.com.au Ph: +61 8 9219 7111 General Shareholder Enquiries info@triangleenergy.com.au About Triangle Energy (Global) Ltd Triangle Energy (Global) Ltd is an ASX listed (ASX:TEG) oil producer and explorer based in Perth, Western Australia.
