Result of Placing and Subscription

Helix Exploration is pleased to confirm, further to the announcement made on 23 January 2025 (the "Launch Announcement"), the successful completion of the Placing and Subscription at the Issue Price of 15 pence per share.

The Placing and the Subscription have conditionally raised, in aggregate, gross proceeds of approximately £5 million pursuant to the placing of 29,570,000 Placing Shares and through the issue of 3,763,333 Subscription Shares ("together the "Capital Raising Shares").

Hannam & Partners, and Tavira acted as Co-lead bookrunners and joint brokers in connection with the Placing alongside Oak Securities and SI Capital. The Placing was conducted by way of an accelerated book build process.

Following the deduction of associated fees and expenses, the net proceeds receivable by the Company will be used principally to:

o  Install and equip PSA Processing Plant and Membrane Unit at Rudyard.

o  Fund the drilling of two additional production wells at Rudyard.

o  The Company will also utilise any additional net proceeds to fund other exploration and resource definition work across the Company's projects and general working capital requirements.

Capitalised terms used in this announcement (this "Announcement") have the meanings given to them in the Launch Announcement, unless the context provides otherwise.

Fee Shares

In connection to the Capital Raising, the Company has issued 66,667 new Ordinary Shares at the Issue Price in lieu of fees ("Fee Shares" together with the Capital Raising Shares, the "New Shares").

Admission and Dealings

Application will be made to London Stock Exchange for the New Shares to be admitted to trading on AIM. It is currently expected that Admission of the New Shares will take place on or before 8.00 a.m. on or around 29 January 2025 and dealings in the New Shares on AIM will commence at the same time.

The Placing is conditional upon, among other things, Admission becoming effective and the Placing Agreement not being terminated in accordance with its terms. The Subscription is conditional on, among other things, Admission becoming effective and the Subscription Letters and the Placing Agreement not being terminated on or before Admission.

The New Shares, when issued, will be fully paid and will rank pari passu in all respects with the existing Ordinary Shares, including the right to receive all dividends and other distributions declared, made or paid after the date of issue.

Total Voting Rights

Following admission of the New Shares, the Company's issued and fully paid share capital will consist of 156,970,000 Ordinary Shares, all of which carry one voting right per share. The Company does not hold any Ordinary Shares in treasury. Therefore, the total number of ordinary shares and voting rights in the Company will be 156,970,000. This figure may be used by Shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

This Announcement should be read in its entirety. In particular, you should read and understand the information provided in the "Important Notices" section of this Announcement.

Notes to Editors

Helix Exploration is a helium exploration company focused on the exploration and development of helium deposits within the 'Montana Helium Fairway'. Founded by industry experts with extensive experience of helium systems in the US, the Company listed in April 2024 raising £7.5 million from an offer book of over £22 million.

The Company has drilled two wells on two assets in 2024.  Darwin #1 well at Rudyard Project tested 236ft in the Souris and Red River formations, flowing 2,750 Mcf/day at 1.1% helium.  Rudyard field can support multiple production wells on structure with each well having the potential to produce pre-tax cashflow of circa $4.0 million per year and drain a large area over a sustained period.

Clink #1 well at Ingomar Dome Project recovered gas samples from the Flathead Formation assayed at 55.2% Hydrogen in gas sample isolated from drilling mud and 2.5% helium in gas sample recovered from the reservoir.  Gas samples demonstrate helium and hydrogen potential with additional stimulation required to potentially generate commercial flow rates in Flathead and Charles formations.

Helix Exploration is focussed on early production at the Rudyard Projects, taking advantage of existing infrastructure and low-cost processing to target first gas production in 2025.  Helix is committed to open and transparent communication with investors and the wider market as the project progresses through development into production.

The Company's Admission Document, and other information required pursuant to AIM Rule 26, is available on the Company's website at https://www.helixexploration.com/.
