History
Triangle moved from a receivership shell to a Sumatran gas producer, then to Cliff Head oil and Perth Basin exploration, before Pilot's collapse and unmet decommissioning exposure led to administration and delisting in 2026.
2007-2009: From receivership to a coal bet
The company began as White Sands Petroleum, already in receivership and under a deed of company arrangement when it proposed a raising of up to US$60 million in August 2007 and a new name, Maverick Drilling International. By May 2008 it was still in receivership and offered shares at 1 cent to recapitalise. In July 2008 it agreed to earn 30% of the Loopleegte coal project in South Africa for 98.5 million shares. The first drilling, in March 2009, found coal in only two of eight holes, and a fault displaced the coal in the western half, which tempered the earlier target.
2009-2015: Pase gas and the long wait for a licence
In September 2009 the company agreed to buy Triangle Energy Limited, owner of the Pase gas contract in North Sumatra, Indonesia, for 1,018,300,000 shares. It turned a coal explorer into a gas producer. The deal completed in December 2009 after a 3-for-1 share consolidation, and the board was replaced by Triangle's nominees. Restarted wells lifted capacity to 7.3 million cubic feet a day. A maiden dividend followed in September 2010.
The contract was due to expire in February 2012, and renewal dragged on. A 2011 share purchase plan at 5.5c funded well work-overs, which had mixed results, and Standard Chartered Private Equity also provided a convertible note. The notes were fully repaid by January 2013, leaving no debt. Meanwhile the route to a new licence shifted to Aceh government partners. A Morocco letter of intent in 2012 was dropped in 2014. Funding shrank to small raisings, including a placement at 0.8c in 2013 and rights issues and placements at 0.1c in 2014 and 2015. Shares on issue rose from about 1.4 billion at the end of 2012 to over 3.3 billion by the end of 2015. In February 2015 the regulator confirmed a 20-year Pase licence.
2015-2016: Selling Pase
Triangle then reversed course and agreed in July 2015 to sell Pase to PT Enso Asia. ASX objected to the break fee, the terms were amended, and a rival consortium bid appeared before PTEA raised its offer to up to US$39.9 million. Shareholders approved it in December 2015, and the sale completed in February 2016 for US$4.5 million cash, plus cost recovery of up to US$7 million and a capped royalty.
2016-2019: Cliff Head, Xanadu and a growing portfolio
In June 2016 Triangle bought AWE's 57.5% of the Cliff Head oil field in Western Australia for A$3.2 million. In May 2017 it took its interest to 78.75% by buying out ROC's share alongside Royal Energy, and in July 2018 it became operator. It also earned 30% of the TP/15 permit by funding part of the Xanadu-1 well. That well was confirmed as an oil discovery in September 2017. In 2017 it spun out Reids Dome into State Gas, keeping 35.47%. A Tamarind loan was converted into shares and repaid by June 2019. In late 2018 Triangle raised about A$5 million to lift its Xanadu stake to 45%. Production hiccups included a minor spill in July 2018 and well pump failures. In October 2019 new seismic suggested the area updip of Xanadu-1 was likely marginal.
2020-2022: Losing the buyer, finding a new route
In 2020 low oil prices brought cost cuts, and Triangle raised money at 3c, including A$3.91 million from a share purchase plan. After BP announced the Kwinana refinery's closure, Triangle withdrew its reserve figures in November 2020. BP terminated the crude supply deal, then agreed storage and a BP Singapore offtake, and reserves were reinstated in October 2021. A A$10 million placement at 2.2c followed in 2021. The WA-481-P purchase from Pilot lapsed in February 2022. The board was replaced that month, with Greg Hancock as chairman. After the final Kwinana lifting in May 2022, Cliff Head crude was exported via Geraldton. Triangle also bought Key's interests and Pilot's share of EP 437 to reach 100% of the L7 and EP 437 permits, and sold half its State Gas stake for A$6.72 million.
2023-2025: Perth Basin disappointment and a Cliff Head sale
Triangle farmed out 25% each of L7 and EP 437 to Talon and New Zealand Oil & Gas. It agreed to sell Cliff Head to Pilot, with the terms revised several times. Production stopped from August 2024. Pilot missed several payments, and in March 2025 payment was deferred to September 2026 against a A$5.563 million secured note. Raisings in 2024 funded drilling, but Booth-1 (August 2024) and Becos-1 (April 2025) were both dry. Strike and Echelon withdrew from the permits in June 2025, and Triangle sued each for A$3.84 million. Triangle also took UK permits, and was awarded Philippine permits in October 2025.
2026: Spin-out and collapse
In May 2026 Triangle distributed its Philippine permits to shareholders through Tetragon Energy, with a A$2.09 million capital reduction. Rory McGoldrick became CEO. In June 2026 Triangle held 100% of L7 and EP 437 after Strike and Echelon transferred their interests back. Pilot entered administration on 14 July, and Triangle's shares were suspended. On 21 July Triangle and three subsidiaries entered voluntary administration under Bryan Hughes, citing inability to meet potential decommissioning obligations. ASX ruled its financial condition inadequate. It was removed from the official list on 28 August 2026 for unpaid fees. The outcome for shareholders is unknown.
