3 Sept 2026drilling result▲ GoodMajor
Logs and mud logs show a third oil zone, the M sand, in Bunian 6. It has not been seen before in the Bunian field but is the main producing zone in the neighbouring Tangai field. It will be tested when the well starts; reserve impact is yet to be quantified.
26 Aug 2026drilling result▲ GoodMajor
Bunian 6 reached 1,807.9 m and logs show oil pay in the TRM3 and K1 sandstones, in line with pre-drill expectations. It will be completed as a producer and come online in early September, targeting field output rising from 250 to 750 bopd. Well flow rates are not yet tested.
21 Aug 2026drilling progress report● Neutral
A replacement top drive got Bunian 6 drilling again, reaching 1,573 m of a planned ~1,820 m. Logging and completion are now expected by end of August, with production shortly after. No result yet.
20 Aug 2026production update● Neutral
July sales were A$405,527 as rain stopped Cooper trucking, though output held at 221 bopd. Trucking restarted in August (1,548 barrels at A$125.04). Vanessa engineering continues with a pipeline survey due September; Kiwi 3D reinterpretation is encouraging.
14 Aug 2026drilling progress report▼ Bad
Bunian 6 casing was cemented and the wellhead and blowout preventers tested, but the rig stopped at 1,257 m to repair the top drive hydraulics. Drilling of the final section is yet to restart. Online still stated as late August, which now looks tight (inference).
7 Aug 2026drilling progress report● Neutral
Bunian 6 was drilled to 1,257 m, the intermediate casing depth, and the rig was running the 9-5/8 in casing. Next: cement it and drill the production hole to about 1,820 m. Online still stated as late August. No result yet.
31 July 2026drilling progress report● Neutral
Bunian 6 drilling resumed after the mud pump fix and reached 1,144 m. Intermediate casing point is now about 1,300 m, then the production section to about 1,820 m. Online still expected late August.
24 July 2026drilling progress report● Neutral
A replacement mud pump was installed at Bunian 6 and was being tested at 1,012 m before drilling resumes. Plan is to finish this section to about 1,440 m, then set casing. Online still late August.
17 July 2026drilling progress report▼ Bad
Bunian 6 drilling is suspended at 1,012 m awaiting replacement mud pumps, with restart expected around 24 July. The online date moves from early July to late August, a delay to the extra production Bass is targeting.
17 July 2026production update● Neutral
June sales revenue was A$561,477, with group output averaging 225 bopd. Cooper sales were cut by rain closing roads. Bunian 6 is now due online late August, later than the early July previously given. Vanessa completed mid-June.
10 July 2026drilling progress report▼ Bad
Bunian 6 reached 1,012 m, only 117 m of progress in the week, and the rig stopped for mud pump repairs. The report still says online early July, though the drilling has not reached the casing point.
3 July 2026drilling progress report● Neutral
Bunian 6 was drilled from 403 m to 895 m this week, heading for about 1,400 m before intermediate casing. Total depth is still about 1,820 m. The report still says online in early July, which looks unlikely given the depth so far (inference).
26 June 2026drilling progress report● Neutral
Bunian 6 surface casing cementing was completed and the blowout preventer installed and tested after some rig repair downtime. Drilling the next section from 403 m continues. Online date still stated as early July. No result yet.
24 June 2026other● Neutral
Bass released the top 20 holder and distribution schedule for the new quoted BASOD options (A$0.0945, expiring 23 June 2028 per the announcement). 31,746,033 options were issued; PAC Partners holds the largest parcel, 2,817,444 (8.87%). Completes the 29 May prospectus offer.
19 June 2026drilling progress report● Neutral
Bunian 6 was drilled to 403 m and surface casing was run and cemented. Target depth is still about 1,820 m, with production expected to rise from 250 to 750 bopd, online early July. No result yet.
17 June 2026asset acquisition disposition▲ GoodMajor
Bass completed the acquisition of 100% of the Vanessa gas field (PPL 268 and PRL 135) after South Australian regulator approval, the last step pending since the earlier transfer paperwork. First gas sales are expected by end 2026 after recommissioning.
15 June 2026production update● Neutral
May output averaged 219 bopd; sales revenue A$735,630. Bunian 6 began drilling 5 June. The Vanessa transfer is still with the regulator for finalising, and the Kiwi grant deed was signed in May. Dundinna seismic reprocessing is almost complete.
12 June 2026drilling progress report● Neutral
Bunian 6 was drilling ahead at 193 m on 12 June, heading to a surface casing depth of 410 m. Target depth remains ~1,820 m, with production still expected to rise from 250 to 750 bopd in early July. No new result yet.
9 June 2026drilling spud▲ GoodMajor
Drilling of Bunian 6 in Indonesia began 5 June, about a month later than the 'early May' timing previously given. It targets ~1,820 m over about 30 days, aiming to lift field output from 250 to 750 bopd, online early July. Bass (55%) rates success at 80%; cost recoverable.

14 May 2026investor presentation● Neutral
May 2026 AGM presentation. Visible text is only the disclaimer, so no new facts can be drawn; it presumably repeats known Vanessa, Kiwi and Indonesian news.
21 Apr 2026production update● Neutral

February output averaged 220 bopd; sales only A$266,290 because heavy rain suspended Cooper oil trucking, with oil stored on site. Sales are expected to resume in early April with a catch-up. Vanessa approval was confirmed by the regulator; the letter is still to come.
26 Mar 2026resource reserve update● NeutralMajor
At 31 December 2025, 2P oil reserves were 0.796 million barrels, largely unchanged from 0.789m. 2C contingent resources were 1.824 million barrels of oil equivalent (from 1.792m). Kiwi gas resources are unchanged, with front-end engineering work planned in 2026.
