History

Comet Ridge moved from small US oil and gas exploration to Australian coal seam gas, and by August 2026 held 100% of the Mahalo Gas Hub.

2006-2008: US exploration and the Pine Brook deal

Comet Ridge began this record chasing oil and gas prospects in Colorado and Washington State, among them Tow Creek, Bear River, Florence and a 420,000-acre option at Grays Harbor. It also drilled Mahalo 2 in Queensland, which showed no measurable flow but still earned the company a 40% interest. Money came from placements and an entitlement issue in late 2006 that raised the full $7.66m at 27 cents. The drilling went badly: the Coal View 31-4 well at Tow Creek got stuck and was abandoned again in 2007. A 2008 entitlement issue was withdrawn with nothing raised, and a farm-in with Freedom Natural Resources collapsed. In June 2008 the US assets went into a new company, Comet Ridge Resources, for 43.75%, backed by Pine Brook. Pine Brook's later investment cut that to 27.18%. In November 2008, with cash of about A$750,000, the Managing Director resigned after about ten weeks.

2009-2011: Merger and Galilee discovery work

The fix was a merger with unlisted Chartwell Energy, which brought about A$8m of cash and New Zealand coal seam gas permits. Chartwell holders received about 55% of the merged company, and Tor McCaul became Managing Director. A placement and an entitlement offer in mid-2009 raised about A$21m. The company was awarded the Galilee Basin permits ATP 743 and 744, about 13,000 sq km at 100%, and drilled core holes there in 2009-10. Its first certified resources followed: Mahalo in October 2010 and the Gunn area in the Galilee in November 2010. It lifted its stake in Gunnedah permit PEL 428 to 40%. In New Zealand, Macdonald 4P succeeded but Macdonald 6P was abandoned. In 2011 the US venture sold its Sweet Pea area, and Comet Ridge received about US$3.5m. Selling 5% of Mahalo to Stanwell for A$7m, completed in December 2011, took its stake to 35%.

2012-2015: Pilots, dilution and first reserves

In 2012 Comet Ridge drilled four Mahalo pilot wells and three Galilee wells, and added Gunnedah interests bought from Petrel Energy. It raised about A$9.4m at A$0.10 in a rights-style offer. The US venture agreed to sell Florence for US$12.25m. The Mahalo pilots disappointed in 2013, losing productivity and needing work-overs, so a A$9m placement at A$0.18 followed and the first reserves target slipped. Stanwell handed its 5% back in 2014, restoring COI to 40%, in return for a later gas sales agreement or A$20m cash. The first certified Mahalo reserves came in August 2014 at 22 PJ (2P). A 59.3m-share placement at A$0.135 funded Mahalo 7, the first horizontal well. By December 2015 the 2P figure had risen to 30 PJ.

2016-2019: Mira and the Mahalo reserves upgrade

Money was tight in 2016, when a raise of about A$2m was priced at A$0.05. Santos then made Comet Ridge its agent for Mahalo subsurface work. Raisings rose through 2017 as results improved: A$5.3m at A$0.125, then $10m at $0.235. The Mira 6 horizontal well was drilled in November 2017, and gas flow topped 1.4 million scf/d in 2018. In March 2018 net 2P reserves rose 473% to 172 PJ. Vintage Energy farmed into the deep sandstone targets in the Galilee, eventually taking 30%, and Albany wells were drilled. A $17.4m placement at $0.34 followed in September 2018. A five-well Mahalo program completed in January 2019. In 2019 Stanwell's option was reworked so Comet would pay $20m if no gas sales agreement was agreed. Comet Ridge became preferred tenderer for Mahalo North and raised $10m at $0.19.

2020-2023: 100% Mahalo blocks and a first sale

A strategic review ended in March 2020 with no demerger; Albany stimulation was suspended because of COVID-19 and low oil prices, and staff pay was cut. Comet Ridge was awarded Mahalo North, Mahalo East and Mahalo Far East, each at 100%. In 2021 it agreed to buy APLNG's 30% of Mahalo for $20m, funded by a Santos loan, and took its first debt, a PURE facility. Mahalo North 1 and 2 were drilled, and Mahalo North 1 reached 1.7 MMcfd in 2022. Completion lifted COI to 70%, then Santos took 12.86% back, leaving 57.14%. A $24m placement at $0.175 followed. Mahalo North's first certified reserves were 42.9 PJ (2P). In September 2023 it signed its first gas sales agreement, with CleanCo, for 21-25 PJ over seven years.

2024-2026: Taking the whole hub

Placements of $15m at $0.17 and about $12m at $0.14 funded further work. A $5m government grant supported Mahalo East, where drilling and testing produced a certification in July 2025 of 51.8 PJ (2P). Comet Ridge also won Mahalo Far East Extension, and Queensland and federal approvals for Mahalo North were received. In December 2025 it agreed to buy Santos's 42.86%. Funding proved hard, so in May 2026 the deal was restructured, and a $40m placement at $0.1025 followed, plus a share purchase plan raising $875,750. The CleanCo agreement was reset so supply starts on 1 January 2030. On 24 August 2026 the purchase completed for $24.42m cash and 83.78m shares, with up to $30m more payable at 10, 20 and 30 PJ of sales. Comet Ridge then held 100% and operated the roughly 1,850 km2 hub, with 361 PJ of 2P reserves. Still open were final investment decision, debt financing, the $9.5m PURE loan due 30 June 2027, and the outcome of the 6 August shareholder meeting.
