KEY HIGHLIGHTS

EXR shares last traded at A$0.14 on May 1, 2026, representing a remarkable 383.33% gain over the prior 12 months, reflecting growing investor interest in the company's Queensland gas exploration activities
All target zones within the Diona-1 exploration well have been successfully stimulated, with the presence of gas observed in return fluids during the post-stimulation flowback period — a positive early indicator ahead of formal flow testing
Diona-1 is strategically located adjacent to the Waggamba gas pipeline, less than 100 metres from the well pad, providing a potential rapid path to market via the Silver Springs Gas Plant to the Wallumbillia Gas Hub on the eastern seaboard

Elixir Energy Limited (ASX:EXR) shares last traded at A$0.14 on May 1, 2026, reflecting a 383.33% gain over the preceding 12 months — one of the more striking share price performances among ASX-listed junior energy explorers over the period. The most recent catalyst for investor attention is the Diona-1 exploration well update released on May 4, 2026, which confirmed successful stimulation of all target zones and the observation of gas during the post-stimulation flowback period. This development is significant because it represents a material step forward in the Diona-1 program and increases confidence in the upcoming formal flow test, which will be the defining operational event for the well in the near term.

DIONA-1 WELL: STIMULATION AND CURRENT OPERATIONS

Stimulation Results

The Diona-1 exploration well is located in the ATP2077 Diona sub-block joint venture in the Surat-Bowen Basin of Queensland, in which Elixir Energy holds a 49% working interest as operator, with Xstate Resources Limited (ASX: XST) holding the remaining 51%. Elixir was fully carried for the drilling of the well by XST under the terms of a transaction agreed in 2025, which means the company incurred no drilling costs for this well — an important financial consideration for a junior explorer.

The fracture stimulation spread was successfully rigged up and all target zones within the Diona-1 well were stimulated, with equipment subsequently demobilised. During the flowback period immediately following stimulation, the presence of gas was observed alongside the return fluids. This hydrocarbon observation is described by the company as boding well for the flow testing phase of operations — while not yet constituting formal production data, the detection of gas during flowback provides an encouraging early signal that the targeted formations contain mobile Hydrocarbons.

Coiled tubing milling operations are currently being finalised before demobilisation, after which the workover rig will rig up to run the production completion. Once the completion is installed, formal flow testing and pressure monitoring operations will commence. Flow test results will represent the next material data point for the well and for the ATP2077 joint venture.

Strategic Location: Proximity to Infrastructure

One of the most commercially significant attributes of the Diona-1 well is its location. The well is situated between the Silver Springs Gas Plant and the Waggamba gas field, with the Waggamba to Silver Springs gas pipeline less than 100 metres from the well pad and an above-ground tie-in point approximately 1,000 metres away. This pipeline connects via the Silver Springs Gas Plant to the Wallumbillia Gas Hub, the spot pricing point for eastern seaboard gas sales.

This infrastructure proximity is a material advantage for the project. Should the well test successfully, the physical and commercial pathway to market is far shorter than is typical for a greenfield exploration well in Australia. Tie-in costs would be modest relative to the potential Revenue stream, and the existing pipeline infrastructure eliminates the need for significant Midstream Capital Investment before first gas sales could commence. For investors assessing the Risk-adjusted upside from a successful Diona-1 flow test, this location advantage is a meaningful differentiator.

TAROOM TROUGH AND BROADER RESOURCE BASE

Elixir Energy's primary asset base is the Taroom Trough in Queensland's Bowen Basin, where the company holds approximately 3.5 TCF of independently certified 2C Contingent Gas Resources following a 24% resource increase announced on April 24, 2026. The Taroom Trough is characterised by its immediate proximity to the Wallumbillia Gas Hub, multiple gas pipelines, 25 million tonnes per annum of LNG export infrastructure, multiple operating refineries, and the mature onshore industry infrastructure of Queensland's gas-producing regions.

The company's strategic objective is to appraise these contingent gas resources and demonstrate reserve conversion and a credible path to commercial production. The Diona-1 well, while located in the Surat-Bowen Basin rather than the core Taroom Trough acreage, represents part of the broader exploration and appraisal program designed to test geological concepts applicable to the wider portfolio. A successful Diona-1 flow test would provide valuable subsurface data and, importantly, a commercial proof-of-concept that could accelerate investor and partner interest in the broader Elixir resource base.

EASTERN AUSTRALIA GAS MARKET CONTEXT

The broader context for Elixir Energy's exploration activities is the ongoing tightening of eastern Australian domestic gas markets. Years of under-Investment in new domestic gas Supply, combined with LNG export commitments, have created periodic periods of domestic gas price Volatility and Supply tightness in the east coast market. New independent gas producers with resources close to existing infrastructure and the Wallumbillia pricing hub are therefore strategically well-positioned relative to more remote exploration plays.

The proximity of Elixir's Taroom Trough acreage to Shell's primary area of Investment across the Basin Centred Gas Play further validates the geological prospectivity of the region. For a junior explorer of Elixir's size, operating in close proximity to a major international oil company's Investment focus provides both geological validation and optionality around potential commercial partnerships or off-take arrangements as the project matures.

FAQs

What was EXR's share price on May 1, 2026?

Elixir Energy shares last traded at A$0.14 on May 1, 2026, up 383.33% over the preceding 12 months.

What is the Diona-1 well and where is it located?

Diona-1 is an exploration well in the ATP2077 Diona sub-block joint venture in the Surat-Bowen Basin of Queensland. Elixir Energy holds a 49% working interest as operator, with Xstate Resources Limited holding 51%. Elixir was fully carried for drilling costs by XST.

What does the gas observation during flowback mean?

During the post-stimulation flowback period, gas was observed alongside the return fluids. This is a positive early indicator that the targeted formations contain mobile hydrocarbons, increasing confidence in the upcoming formal flow testing phase — though it does not yet constitute confirmed production data.

Why is the location of Diona-1 strategically important?

The well is located less than 100 metres from the Waggamba to Silver Springs gas pipeline, with an above-ground tie-in point approximately 1,000 metres away. This pipeline connects to the Wallumbillia Gas Hub — the eastern seaboard gas spot pricing point — meaning a successful test could lead to a rapid path to market.

What is Elixir Energy's primary resource base?

Elixir Energy holds the largest acreage position in the Taroom Trough in Queensland's Bowen Basin, with approximately 3.5 TCF of independently certified 2C Contingent Gas Resources following a 24% resource increase announced on April 24, 2026.
