Helix Exploration PLC

("Helix Exploration" or "Helix" or the "Company")

Rudyard Reserves and Economic Model

and

Proposed Capital Raising to raise a minimum of £4 million

Helix Exploration, the helium exploration and development company with near-term production assets within the Montana Helium Fairway, is pleased to provide the market with updated reserves and results of economic modelling at its Rudyard Project and announces a proposed Capital Raising (as defined below) of not less than £4 million through the issue of a minimum 26,666,667 new ordinary shares of 1 pence each ("Ordinary Shares") at 15 pence (the "Issue Price") per share.

Highlights of Reserves and Economic Modelling

•     Reserves of 355 million cubic feet of helium calculated by Aeon Petroleum Consultants Corp. ("Aeon") on northern dome only

•     Net Revenue $115.2m over 12.5-year life of field and peak sustained post-tax cash flow of $15-25 million per year using a flat helium price of $500/Mcf

•     Aeon modelling results in NPV8 of $77.9m and IRR >1,000% on reserves in northern part of dome

•     In-house modelling results in NPV8 of circa $145m and Net Revenue circa $220m including contingent resources in southern part of dome

•     Results from Darwin #1 indicate closure is larger than expected under current structural model

Bo Sears, CEO of Helix Exploration, said:

"We are delighted to announce updated reserves and economic forecasts for Rudyard Project which demonstrate the potential to generate free cash flow of $15 - $25 million per year post-tax and post-royalty, and net revenue of $115 - $220 million over a 12.5-year life of field.  Reserves demonstrate discovered commercial helium that underly the value of the Rudyard Project and considerable upside for long term shareholders."

"With the expected completion of the proposed fundraise, Helix will be fully funded to bring the Rudyard Project into production and positive cash-flow, targeting first production within Q2 of this year.  Early cashflow gives Helix the freedom to pursue exploration and M&A, self-financing development and growing Helix into a strategic helium producer for the USA market."

David Minchin, Chairman of Helix Exploration, said:

"The decision to move forward with an equity raise comes after a detailed review of the economic model and terms of available debt finance.  Equity became preferable over debt considering the high cost of debt capital as well as onerous terms including long term take-or-pay agreements that would have limited the Company's ability to market produced helium to end-users and the wider USA market.  In-house analysis showed a higher post-dilution NPV per share on an equity raise compared to a debt raise, demonstrating that equity would be the preferred finance route to grow the Company and deliver long-term benefit to shareholders."

"We look forward to an active period for the Company as we move to complete the proposed fundraise and accelerate Rudyard into production."

Reserves

Helix has commissioned Aeon to complete a reserve calculation and economic model on the Rudyard Project, utilising results of the extended well-test completed on the Souris and Red River formations in Darwin #1 well.  Aeon are industry experts with 45 years of experience in economic analysis, production optimisation and reserves estimation and evaluation.

Rudyard Project represents a co-joined anticline with contingent resources of 484 million cubic feet of helium across the both the northern and southern domes, as announced on 20 June 2024. Aeon have calculated updated recoverable helium reserves of 355 million cubic feet of helium within the northern dome based on results of extended well tests conducted at Darwin #1 and in accordance with definitions established by PRMS.  Aeon also calculated updated contingent resources of 280 million cubic feet of helium within the southern dome pending an extended well test within this closure.

¹ Risked data includes a chance of geological discovery of approximately 0.73.

Economic Model

Aeon have analysed pressure drop and rebound results and have calculated that a flow rate of 2,000Mcf of raw gas per day per well can be sustained for five years before decline.  Based on an initial three producing wells and self-financed expansion to six producing wells within the northern dome, and using a flat helium price of $500/Mcf, Aeon have calculated:

·    Net revenue $115.2 million over 12.5-year life of field

·    Peak sustained post-tax cash-flow of $16.5 million per year

·    NPV8 of $77.9 million, and

·    IRR >1,000%. 

These economic numbers include production from reserves from the northern part of co-joined anticline.

The Company has taken input parameters used by Aeon to update its in-house economic model including contingent resources in southern dome. Based on an initial four producing wells and self-financed expansion to ten producing wells, and using a helium price of $500/Mcf, the in-house economic model demonstrates:

·    NPV8 of $146 million

·    Net revenue of $220 million over a 12.5-year life of field, and

·    Peak sustained post-tax cash-flow of $28 million per year. 

The in-house model shows potential upside that could be achieved by a successful extended well test in the southern part of the co-joined anticline.

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" and/or "distributor" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that the Placing Shares are: (i) compatible with an end target market of: (a) investors who meet the criteria of professional clients and (b) eligible counterparties (each as defined in MiFID II); and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "EU Target Market Assessment").

Notwithstanding the UK Target Market Assessment and the EU Target Market Assessment, distributors should note that: the price of the Ordinary Shares may decline and investors could lose all or part of their investment; the Ordinary Shares offer no guaranteed income and no capital protection; and an investment in the Ordinary Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom.

Each of the UK Target Market Assessment and the EU Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the UK Target Market Assessment and the EU Target Market Assessment, the Joint Broker will only procure investors who meet the criteria of professional clients and eligible counterparties each as defined under COBS or MiFID II, as applicable.

For the avoidance of doubt, each of the UK Target Market Assessment and the EU Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A respectively of COBS or MiFID II, as applicable; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Ordinary Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the Placing Shares and determining appropriate distribution channels.

Persons (including, without limitation, nominees and trustees) who have a contractual or other legal obligation to forward a copy of this Appendix or the Announcement of which it forms part should seek appropriate advice before taking any action.

The Terms and Conditions should be read in their entirety.

Conditions of the Placing

The Placing is conditional upon the Placing Agreement becoming unconditional and not having been terminated in accordance with its terms.

The Joint Brokers' obligations under the Placing Agreement in respect of the Placing Shares are conditional on, inter alia:

1.    the delivery by the Company to the Joint Brokers of certain documents required under the Placing Agreement;

2.    the Company having performed its obligations under the Placing Agreement to the extent that such obligations fall to be performed prior to Admission;

6.    the Placing Agreement not having been terminated by the Joint Brokers in accordance with its terms.

If: (i) any of the conditions contained in the Placing Agreement, including those described above, are not fulfilled or (where applicable) waived by the Joint Brokers by the respective time or date where specified (or such later time or date as the Joint Brokers may notify to the Company, being not later than the Long Stop Date); (ii) any of such conditions becomes incapable of being fulfilled; or (iii) the Placing Agreement is terminated in the circumstances specified below, the Placing will not proceed and the Placees' rights and obligations hereunder in relation to the Placing Shares shall cease and terminate at such time and each Placee agrees that no claim can be made by the Placee in respect thereof.

The Joint Brokers may, at their discretion and upon such terms as it thinks fit, waive, or extend the period for (subject to the Long Stop Date), compliance by the Company with the whole or any part of any of the Company's obligations in relation to the conditions in the Placing Agreement save that the condition relating to Admission taking place may not be waived. Any such extension or waiver will not affect Placees' commitments as set out in this Announcement.

Neither the Joint Brokers, the Company nor any of their respective affiliates, agents, directors, officers or employees shall have any liability to any Placee (or to any other person whether acting on behalf of a Placee or otherwise) in respect of any decision they may make as to whether or not to waive or to extend the time and/or date for the satisfaction of any condition to the Placing nor for any decision they may make as to the satisfaction of any condition or in respect of the Placing generally and, by participating in the Placing, each Placee agrees that any such decision is within the absolute discretion of the Joint Brokers.

Right to terminate the Placing Agreement

The Joint Brokers are entitled, at any time before Admission, to terminate the Placing Agreement by giving notice to the Company in certain circumstances, including, inter alia, if before Admission:

1.    the Joint Brokers becoming aware of any fact, matter or circumstance which constitutes or might reasonably be expected to constitute a material breach of the warranties given in the Placing Agreement or which indicates that any of such warranties has become or might reasonably be expected to become untrue, inaccurate or misleading in any material respect by reference to the facts and circumstances then subsisting;

2.    the Company has failed to comply with its obligations under the Placing Agreement, or with the requirements of any applicable laws or regulations (including MAR and the AIM Rules) in relation to the Placing;

3.    any of the conditions set out in the Placing Agreement are not fulfilled or (if capable of waiver) waived by the Joint Brokers or shall have become incapable of being fulfilled by the respective time(s) and date(s) (if any) specified in the Placing Agreement;

4.    there occurs or arises prior to Admission any significant change or new material matter which the Joint Brokers, in their discretion, determines should be notified to Placees or Shareholders; or

5.    there has been a change in national or international financial, political, economic, monetary or stock market conditions (primary or secondary) or an imposition of or compliance with any law or governmental or regulatory order, rule, regulation, restriction or direction,

which, in the opinion of the Joint Brokers, would or would be likely to prejudice materially the Company or render the Placing (or any material part thereof) or Admission impractical or inadvisable.

The rights and obligations of the Placees will not be subject to termination by the Placees or any prospective Placees at any time or in any circumstances. By participating in the Placing, Placees agree that the exercise by the Joint Brokers of any right of termination or other discretion under the Placing Agreement shall be within the absolute discretion of the Joint Brokers and that the Joint Brokers need not make any reference to Placees in this regard and that neither the Joint Brokers nor any of their respective affiliates shall have any liability to Placees whatsoever in connection with any such exercise or failure so to exercise.

No Admission Document or Prospectus

The Placing Shares are being offered to a limited number of specifically invited persons only and have not been nor will they be offered in such a way as to require the publication of a prospectus in the United Kingdom or otherwise. No offering document, admission document or prospectus has been or will be submitted to be approved by the FCA or the London Stock Exchange in relation to the Placing or the Placing Shares, and Placees' commitments will be made solely on the basis of the information contained in the Announcement (including this Appendix) and the Publicly Available Information.  Each Placee, by accepting a participation in the Placing, agrees that the content of this Announcement is exclusively the responsibility of the Company and confirms that it has not relied on any other information (other than the Publicly Available Information), representation, warranty, or statement made by or on behalf of the Company, Cairn or the Joint Brokers or any other person and neither the Joint Brokers, Cairn, the Company nor any other person will be liable for any Placee's decision to participate in the Placing based on any other information, representation, warranty or statement which the Placees may have obtained or received and, if given or made, such information, representation, warranty or statement must not be relied upon as having been authorised by the Joint Broker, Cairn, the Company or their respective officers, directors, employees or agents. Each Placee acknowledges and agrees that it has relied on its own investigation of the business, financial or other position of the Company in accepting a participation in the Placing. Neither the Company, Cairn nor the Joint Brokers are making any undertaking or warranty to any Placee regarding the legality of an investment in the Placing Shares by such Placee under any legal, investment or similar laws or regulations. Each Placee should not consider any information in this Announcement to be legal, tax, financial, business or other advice. Each Placee should consult its own solicitor, tax adviser and financial adviser for independent legal, tax and financial advice regarding an investment in the Placing Shares. Nothing in this paragraph shall exclude the liability of any person for fraudulent misrepresentation.

Registration and Settlement

Following closure of the Bookbuild, each Placee allocated Placing Shares in the Placing will be sent a trade confirmation or contract note in accordance with the standing arrangements in place with the Joint Broker with whom they have dealt, stating the number of Placing Shares allocated to it at the Issue Price, the aggregate amount owed by such Placee (in pounds sterling) and a form of confirmation in relation to settlement instructions.

Each Placee will be deemed to agree that it will do all things necessary to ensure that delivery and payment is completed as directed by the Joint Broker with whom they have dealt in accordance with the standing CREST settlement instructions which they have in place with that applicable Joint Broker.

Settlement of transactions in the Placing Shares (ISIN: GB00BPK66X70) following Admission will take place within CREST provided that, subject to certain exceptions, the Joint Brokers reserve the right to require settlement for, and delivery of, the Placing Shares (or a portion thereof) to Placees by such other means that it deems necessary if delivery or settlement is not possible or practicable within CREST within the timetable set out in this Announcement or would not be consistent with the regulatory requirements in any Placee's jurisdiction.

It is expected that settlement will take place in accordance with the instructions set out in the contract note.

Interest is chargeable daily on payments not received from Placees on the due date(s) in accordance with the arrangements set out above at the rate of 4 percentage points above the prevailing Sterling Overnight Index Average (SONIA) rate as determined by the Joint Brokers.

Each Placee is deemed to agree that, if it does not comply with these obligations, the Joint Brokers may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, for the Joint Brokers' account and benefit (as agent for the Company), an amount equal to the aggregate amount owed by the Placee plus any interest due. The relevant Placee will, however, remain liable and shall indemnify the Joint Brokers on demand for any shortfall below the aggregate amount owed by it and may be required to bear any stamp duty or stamp duty reserve tax or securities transfer tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares on such Placee's behalf. By communicating a bid for Placing Shares, each Placee confers on the Joint Brokers such authorities and powers necessary to carry out any such sale and agrees to ratify and confirm all actions which the Joint Brokers lawfully take in pursuance of such sale. Legal and/or beneficial title in and to any Placing Shares shall not pass to the relevant Placee until it has fully complied with its obligations hereunder.

If Placing Shares are to be delivered to a custodian or settlement agent, Placees should ensure that the form of confirmation is copied and delivered immediately to the relevant person within that organisation.

Insofar as Placing Shares are registered in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares should, subject as provided below, be so registered free from any liability to UK stamp duty or stamp duty reserve tax or securities transfer tax. Neither the Joint Brokers nor the Company will be liable in any circumstances for the payment of stamp duty, stamp duty reserve tax or securities transfer tax in connection with any of the Placing Shares. Placees will not be entitled to receive any fee or commission in connection with the Placing.

The agreement to settle a Placee's subscription and/or purchase (and/or the subscription of a person for whom such Placee is contracting as agent) free of stamp duty and stamp duty reserve tax depends on the settlement relating only to a subscription by it and/or such person direct from the Company for the Placing Shares in question. Such agreement assumes that the Placing Shares are not being subscribed for in connection with arrangements to issue depositary receipts or to transfer the Placing Shares into a clearance service. If there are any such arrangements, or the settlement relates to any other subsequent dealing in the Placing Shares, stamp duty or stamp duty reserve tax may be payable, for which neither the Company or the Joint Brokers will be responsible, and the Placee to whom (or on behalf of whom, or in respect of the person for whom it is participating in the Placing as an agent or nominee) the allocation, allotment, issue or delivery of Placing Shares has given rise to such UK stamp duty or stamp duty reserve tax undertakes to pay such UK stamp duty or stamp duty reserve tax forthwith and to indemnify on an after-tax basis and to hold harmless the Company and the Joint Brokers in the event that any of the Company and/or the Joint Brokers have incurred any such liability to UK stamp duty or stamp duty reserve tax. If this is the case, each Placee should seek its own advice and notify the Joint Brokers accordingly.

In addition, Placees should note that they will be liable for any stamp duty and all other stamp, issue, securities, transfer, registration, documentary or other duties or taxes (including any interest, fines or penalties relating thereto) payable outside the UK by them or any other person on the subscription or purchase by them of any Placing Shares or the agreement by them to subscribe for or purchase any Placing Shares.

All times and dates in this Announcement (including the Appendices) may be subject to amendment. The Joint Brokers shall notify the Placees and any person acting on behalf of the Placees of any changes.

This Announcement has been issued by, and is the sole responsibility, of the Company. No representation or warranty express or implied, is or will be made as to, or in relation to, and no responsibility or liability is or will be accepted by the Joint Brokers, Cairn or by any of their respective affiliates or agents as to or in relation to, the accuracy or completeness of this Announcement or any other written or oral information made available to or publicly available to any interested party or its advisers, and any liability therefore is expressly disclaimed.

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.
