Completed purchase of Lone Star's US oil and gas interests, a Stonehorse subsidiary, for US$1.114m (~US$9,100 per flowing BOE/d). Adds ~123 BOE/d, about 9% of Q2 production, with no new shares issued. Stonehorse is Brookside's Orion partner.
2 Sept 2026 · AXP Energy Limited
The 320kW gas-to-power unit is operating with 99% uptime. Charlie #1 flowed 11 bbl of oil in a one-hour test, choked to ~100 psi; the company says this is not a stable daily rate. A 10-day flow test follows.
1 Sept 2026 · Jupiter Energy Ltd
The four noteholders extended the interest-free period on their notes from 31 December 2026 to 31 December 2028, resolving the earlier May 2025 proposal. A further US$300,000 was repaid in late August, leaving US$13.87m. The text does not mention the AIX listing.

1 Sept 2026 · 3D Oil
RISC valued TDO's 20% VIC/P79 interest at US$19.8m (A$28.6m): US$13.0m for Essington, risked at 51%, plus US$6.8m exploration value. ConocoPhillips can buy until 24 September 2026, at that value less the default claim, interest and a discount. TDO says it materially undervalues the interest and disputes the notices' validity.

The PEL 93 joint venture applied to enter the Second Renewal Exploration Period from 3 October 2026, proposing at least one exploration well and relinquishing 50% of the area.

31 Aug 2026 · AXP Energy Limited
AXP and Simpora mutually terminated the Syria Block 9 farm-in, citing timing against AXP's Oklahoma priorities. Simpora keeps the US$100,000 deposit; no further payments are due. This reverses the June 'transformational' deal, with the US$1m payment never made.
