Particularly, it will be those existing Shareholders of the Company who are registered as holders of Shares at 7pm (Melbourne time) on 20 May 2025 and whose registered address is in Australia being those Shareholders who are eligible to participate in the Company's Entitlement Offer to raise up to $3,100,000, to which the issue of Options relate. Shortfall Offer The Company expects that an investment in Options under the Shortfall Offer will be suitable for: Investment Timeframe • new and existing institutional, sophisticated or professional investors that are invited to invest in the Company to gain exposure to equities in / seek to profit from an appreciation in the market price of shares in a small-cap mining exploration company listed on the ASX; and • who are in a position to pay any exercise amounts in relation to the Options in due course. The target market of investors will take a short to medium term outlook on their investment. Investors with a short-term outlook for their investment will benefit from an ability to exercise Options and trade the underlying Shares issued on exercise should the Option exercise price of the Options be lower than the trading price of Shares. Investors with a medium-term outlook will benefit from an ability to exercise the Options within their 3 year exercise period and increase their shareholding and exposure to the potential upside in the Company’s Shares into the future. Given the need to pay the exercise price in order to acquire Shares, Investors in the target market are in a financial position that is sufficient for them to invest their funds on exercise the Options over a three year time horizon, during which their ability to liquidate their Options in the Company may be limited by a lack of liquidity in the Options and by the trading price of the underlying Shares. Investment Metrics Doc ID: 500265467.1 While the Company does not have an established eligibility framework for investors based on metrics such as age, expected return or volatility, it is expected that the target 2 Factor Target market market of investors will be able to withstand potential fluctuations in the value of their investment. The Options offer no guaranteed income or capital protection. Risk 3 The Company considers that an investment in the Options is highly speculative, such that an investment in the Company is not appropriate for an investor who would not be able to bear a loss of some or all of the investment. Investors should also have a sufficient level of financial literacy and resources (either alone or in conjunction with an appropriate adviser) to understand and appreciate the risks of investing in Options as an asset class generally and the more specific risks of investing in an Australian listed smallcap gas exploration and appraisal company. DISTRIBUTION CONDITIONS The Entitlement Offer is being directly offered to Eligible Shareholders who hold shares at the Record Date. Any Entitlements not taken up under the Entitlement Offer will form a shortfall and Eligible Shareholders may subscribe for additional securities. Any remaining shortfall may be placed by the Company following the close of the Entitlement Offer. The Prospectus will include jurisdictional conditions on eligibility. The Company will also include on its web landing page for the Entitlement Offer a copy of this TMD and require that retail clients confirm that they meet the eligibility criteria of the expected target market outlined in this TMD before they apply for Options. The Company considers that these distribution conditions will ensure that persons who invest in Options under the Entitlement Offer fall within the target market in circumstances where personal advice is not being provided to those persons by the Company. 4 REVIEW TRIGGERS The Options are being offered for a limited offer period set out in the Prospectus, after the conclusion of which the Options will no longer be available for investment by way of issue. It follows that the TMD will only apply in the period between 14 May 2025 and the issue of the Options shortly after the close of the Entitlement Offer (or Shortfall Offer, where applicable) (Offer Period).
