History
A Moroccan and Gabon oil explorer that lost its big wells and pivoted to North Sea gas as Hartshead, before ACAM bought it for A$0.014 a share in 2026.
2011-2014: Morocco and a second African project
Pura Vida Energy NL, the company later known as Hartshead, issued a prospectus in November 2011 to raise $4,000,000 at $0.20 a share for the Mazagan offshore permit in Morocco. The offer closed oversubscribed, and the company joined the ASX on 10 February 2012 with 38,780,001 shares. Independent estimates of Mazagan's prospective resources (oil not yet drilled) rose through 2012, to 7.0 billion barrels gross by September. Placements followed at 25 cents in July and 70 cents in November.
In January 2013 Plains Exploration & Production agreed to take 52% of Mazagan and operate it, paying US$15m and carrying costs up to US$215m. The same month Pura Vida won 80% and operatorship of the Nkembe block offshore Gabon. Money came from placements at $0.39 in May, 58 cents in September and $0.63 in December, plus a 20% interest loan. The Mazagan farmout completed in November 2013, leaving Pura Vida with 23% and cash of A$22m. That month it also agreed to farm into 50% of the Ambilobe block off Madagascar, completed in December.
2015-2016: The dry hole
The first Mazagan well, MZ-1, was moved to the Ouanoukrim prospect and slipped from early 2015 to a May spud. In July and August it found no reservoir or oil shows in the Cretaceous or Jurassic targets and was abandoned as a dry hole. The company called it a set-back, and the operator cancelled its drillship slot.
In February 2016 the company raised about $2.7m at $0.027, against $0.36 paid in 2015, citing value lost after the dry hole and low oil prices. Shareholders took up only part of the rights issue, and professional investors covered the shortfall. Sterling Energy withdrew from Ambilobe, so Pura Vida took 100% at no cost. Chairman Jeff Dowling resigned, fees and salaries were cut, and staff fell to seven. In September a settlement over the second Mazagan well began, and it completed in January 2017 with US$7m and 2,376 tonnes of drilling equipment, after which Pura Vida left the permit.
2017-2019: Gabon in dispute
A rig contractor term sheet for Nkembe expired in April 2017, and the CEO's employment ended in March. Spending on Nkembe stopped. By October 2017 cash was about $10.5m, and the board was looking at other industries. Havoc was given an option over Nkembe, but Gabon's regulator said phase one expired in January 2018, against the company's view of December 2019. The regulator demanded US$17m of work commitments; the company claimed force majeure and refused to pay. The dispute stayed unresolved, with Gabon in January 2019 saying the company was released from its interest yet still owed commitments.
The company also bought 14.7% of Jacka Resources in 2018 and, in July 2019, signed with Gemini Resources to earn 35% of two Polish gas projects by spending A$6.15m. It raised A$1m and A$2.73m at A$0.018 and was renamed Ansila Energy.
2019-2020: Poland falls short
The Siciny-2 test showed methane but formation water blocked gas flow. A December 2019 economic evaluation was retracted after ASX queried its basis. In March 2020, citing COVID-19, weaker oil and investor aversion to unconventional risk, Ansila withdrew from Nowa Sol. Analysis in April found very low permeability. The 1.6 Tcf resource stayed unproven.
2020-2022: Hartshead and the North Sea
In September 2020 Hartshead Resources Ltd, 21.6% owned by Ansila, was provisionally awarded five Southern North Sea blocks. In December Ansila agreed to buy the other 78.4%, with a A$7.0m placement. The deal completed in February 2021 with 1,000,000,000 shares issued to vendors and an A$8.0m placement at A$0.025. The company was renamed Hartshead Resources in May 2021.
Phase I work moved ahead: a concept report went in May 2022, and the regulator raised no objection in July. An audit in June 2022 upgraded Anning and Somerville to reserves of 301.5 Bcf. In August 2022 it raised A$11m by placing 400,000,000 shares at A$0.0275.
2023-2025: Partnering and policy shocks
In April 2023 RockRose Energy took 60% of licence P2607 in a deal worth about A$196.3m, and Hartshead raised A$20m at A$0.04. The field development plan went to the regulator in June 2023. UK tax changes in 2024, including a higher Energy Profits Levy, put the timetable in doubt, and the company cut contractor headcount. It did secure six licences from the 33rd Round, taking total net reserves and resources to about 1.5 Tcf. In February 2025 it submitted a revised export route. In September 2025 RockRose agreed to fund Hartshead's share of Phase C well work, cutting its interest from 40% to 35%.
2025-2026: Sale to ACAM
In December 2025 Hartshead agreed to a scheme under which ACAM would buy 100% at A$0.014 a share, a 133% premium to A$0.006, valuing it at about A$40m. Independent expert BDO found the offer not fair but reasonable. The court approved it on 11 June 2026 and it was implemented on 23 June. ASX removed Hartshead from the official list on 24 June 2026, ending its listing. At 31 December 2025 it had cash of A$13.97m and no debt.
