History
Born as Sunbird Energy, a South African coal-gas and offshore gas explorer that sold up in 2016, the company became Invictus and found gas at Mukuyu in Zimbabwe.
2011-2014: Sunbird and South African gas
Sunbird Energy listed after a prospectus for an IPO raising $9,000,000 at $0.20 a share. It bought 74% of South African coal bed methane projects (gas held in coal seams) and 100% of a Botswana company. Early drilling at Ermelo disappointed, with gas contents lower than expected, but Mopane was better: a second core hole hit 38.2m of net coal, and in November 2013 Mopane received a first contingent resource of 644 Bcf (2C).
In December 2012 Sunbird agreed to buy 76% of the Ibhubesi offshore gas project. A 2013 audit certified 210 Bcf of proved reserves, and a placement of 12.5m shares at $0.40 raised $5m. In December 2013 it signed a non-binding agreement with state utility Eskom on gas supply to the Ankerlig power station. A related-party loan of up to A$5m followed in 2014. The Ibhubesi purchase completed in June 2014, and Vandasia Investments agreed to buy 43.9% of the company, though only the US$5m first stage completed.
2015-2016: Bids, boardroom fights and the sale
In March 2015 Sunbird and PetroSA signed a non-binding term sheet with Eskom for 30 Bcf a year for up to 15 years. Shareholders then challenged the board twice, and Dorian Wrigley joined in May. Glendal Power's non-binding takeover proposal at A$0.18 a share, made in July, was withdrawn in December. Meanwhile the company took on convertible loans at 20% interest.
In July 2016 it sold Ibhubesi and the coal bed methane projects to a consortium of its major shareholders and lenders for about A$1m cash, a buyback of 55m shares and transfer of about A$4.8m of debt. It was left with about A$850,000 net cash, no debt and 84,592,127 shares, and was renamed Interpose Holdings.
2017-2018: Texas dry holes and a pivot
Interpose bought a 7.5% interest in the Gallatin gas project in Texas. Both wells drilled, in 2017, were dry holes. In April 2018 it agreed to buy Invictus Energy Resources, giving an 80% interest and operatorship of the SG4571 permit in Zimbabwe's Cabora Bassa Basin, alongside a A$4.5m raise. Scott Macmillan became Managing Director in June. In November a first independent estimate put the Mzarabani prospect at 3.9 Tcf of gas and 181 million barrels of condensate, undiscovered, and the company stressed no discovery had been made.
2019-2021: Small raisings and seismic
An updated estimate in 2019 lifted the prospective resource to 9.25 Tcf plus 294 million barrels of condensate. Non-binding gas supply memoranda were signed with Sable Chemicals and Tatanga Energy. Funding was thin: a $1.5m placement at $0.026 and small raisings from Mangwana. A farm-in offer in December 2020 ended in July 2021 when due diligence could not be completed.
In March 2021 a A$8.0m placement at $0.11 funded seismic work, and the Petroleum Exploration Development and Production Agreement was signed. The 2D survey finished in November with 839.3km acquired, showing possible hydrocarbon indicators. A December option with Cluff Energy Africa was non-binding.
2022-2023: Drilling Mukuyu
A further A$8m was raised in January 2022, and Exalo's Rig 202 was contracted. The prospect was renamed Mukuyu. Raisings of $12.0m at $0.20 and $25m at $0.23 followed, and Invictus chose to fund two wells itself. Licences grew to about 360,000 ha. Mukuyu-1 spudded in September 2022 and reached 3,923m with gas shows over about 900m, but the hole deteriorated and the tools failed, so no fluid sample was taken and no discovery was declared. Chairman Stuart Lake left; John Bentley replaced him in February 2023.
Raisings at lower prices followed: $10.0m at $0.12 in April 2023, a share purchase plan that raised $12.7m, $12.75m from institutions, and A$15.0m at $0.15 in September. Mukuyu-2 spudded on 20 September 2023. In December it declared two gas discoveries, with preliminary net pay of 34.9m, and Mukuyu-1 was then classed a discovery. A$15.0m was raised at $0.13.
2024-2026: Appraisal, Musuma and a failed funder
Lab results in March 2024 confirmed a rich gas-condensate discovery. A follow-on entitlement offer raised only A$1.49m of up to A$15.2m targeted. A Zimbabwean placement at A$0.10, about US$12m in total, completed in December. Seismic interpretation defined eight eastern prospects, and Musuma-1 was chosen as the next well. Pilot production approvals and a gas-to-power plan for the Eureka Gold Mine progressed.
In August 2025 Al Mansour Holdings agreed to buy 19.9% for A$37.8m. Settlement was deferred twice, and Invictus terminated the agreement in January 2026. A $10m placement at $0.060 followed in April. The Petroleum Production Sharing Agreement was signed on 28 May 2026. As of 7 August 2026, the Musuma-1 spud was confirmed for November 2026 after repeated slippage, wellpad contracts were awarded, a Deed of Variation was signed with Exalo for Rig 202, and some well services contracts were still to be awarded. Invictus remained the sole funder, with no binding farm-out.
