Announcements, explained

Each one in plain English, with the numbers worked through for a shareholder.

18 Aug 2023joint venture update▲ GoodMajor

Valence signed a Surface Land Use Agreement for the Jesse-3 well-pad, keeping the Q4 2023 spud on track. Grand Gulf also received a non-binding farm-in proposal from an unnamed US oil and gas company for Red Helium; no binding deal is guaranteed.

14 Aug 2023material agreement▲ GoodMajor

Valence signed a non-binding heads of agreement with TSX-V-listed Sage Potash. Sage would contribute the greater of US$1m or one third of shared costs to Jesse-3, in return for a potash core, with a 50/50 split on a later 3D seismic survey. It depends on due diligence and approvals.

8 Aug 2023admin correction▼ Bad

After discussions with ASX, Grand Gulf retracted the in-ground value in its 7 August presentation. ASX rules bar forecast financial information derived from prospective resources. Investors are told not to rely on that figure.

7 Aug 2023investor presentation● Neutral

August 2023 Red Helium presentation repeats known facts: 12.7 Bcf prospective resource, Jesse-1A re-completion in Q3/Q4 and Jesse-3 spud in Q4 2023. It also carried a US$6B in-ground value that Grand Gulf retracted the next day.

22 June 2023resource reserve update▲ GoodMajor

Sproule-reviewed estimate adds a McCracken gross P50 prospective helium resource of 1.8 BCF (1.3 BCF net to Valence), lifting the project total to 12.7 BCF from 10.9 BCF. These are unrisked, undiscovered volumes, with Jesse-3 positioned to test them.

8 June 2023drilling scheduled● Neutral

Jesse-3 location chosen on a seismic high 1,300 ft from the old Redd-1 well, potentially up to 70 ft higher than Jesse-1A, with McCracken Sandstone as a secondary target. Permit approval takes 60-70 days, so spud is planned for Q3/Q4 2023.

2 June 2023other▲ Good

Independent engineer Blade Energy Partners modelled Jesse-1A's upper Leadville as potentially flowing 5 MMscfd or more of raw gas after isolation and stimulation. A workover under US$1m is proposed after Jesse-3. This is modelling, not a flow test; it follows Jesse-1A's earlier water-ingress problem.

24 Apr 2023drilling result● NeutralMajor

Jesse-2 reached total depth with a 192 ft gross gas column, flowing gas to surface at up to 0.9% helium with no water, confirming the Jesse discovery. But only 23 ft net pay and lower secondary porosity than Jesse-1A; well suspended. Valence interest rises to 77.5%.

11 Apr 2023drilling progress report▲ Good

Jesse-2 drilled through the roughly 1,900 ft Paradox salt and reached the top of the Leadville target, in line with prediction, with elevated helium shows throughout. It is now setting 7-inch casing before drilling and testing the Leadville. No reservoir result yet.

6 Apr 2023regulatory community update▲ Good

A third Jesse drill permit was approved by Utah regulators, allowing a follow-on development well if Jesse-2 succeeds. Helium shows in the salt section now reach about 71 times background. Reservoir entry is expected the following week.

3 Apr 2023drilling progress report▲ Good

Jesse-2 is drilling at 7,050 ft in the salt seal. Gas analysis shows several zones with helium above background, up to 15 times at 6,308 ft. The company says these are not commercial targets but suggest a working helium system.

29 Mar 2023drilling progress report● Neutral

Jesse-2 reached the top of the Paradox Formation salt seal at 5,928 ft, in line with the geological prediction. The rig is tripping to change the drilling assembly before drilling on towards the Leadville target. Drilling is described as on schedule.

24 Mar 2023capital raising announcement● NeutralMajor

Placement of 113.6m shares at 2.2c raises A$2.5m, with 1-for-2 attaching options at 5c for 3 years plus 28.4m options to lead managers Euroz Hartleys and CPS. Funds are for working capital and long-lead production equipment, if Jesse-2 succeeds. Jesse-2 is drilling the intermediate section.

What it means for a shareholder

114m new shares at A$0.022 to raise about A$2.5m. That's 6.8% dilution: every existing holder's slice gets 6.8% smaller. If you held A$1,000 of shares (45,455 at the issue price), your slice goes from 0.00294% to 0.00274% of the company. To keep it you'd need 3,339 more shares - about A$73 at the issue price.
