16 May 2025

Mosman Oil and Gas Limited

("Mosman" or the "Company") 

£1.25m Placing

Mosman Oil and Gas Limited (AIM: MSMN) the hydrocarbon, helium and hydrogen exploration, development, and production company, confirms it has today raised £1,250,000 (before expenses) by way of a placing of 2,777,777,778 ordinary shares (the "Placing Shares") at a placing price of 0.045p per share (the "Placing Price") (the "Placing").

In addition to the Placing, as the Company greatly values the support of its retail shareholders, the Company also intends to offer its existing retail shareholders a "Retail Offer" of new Ordinary Shares at the same Issue Price as the Placing for up to £300,000.

The Company will release a separate announcement regarding the Retail Offer and its terms. For the avoidance of doubt, the Placing is separate from and does not form part of the Retail Offer.

Progressing Helium Projects

Mosman has a portfolio of helium projects in US and Australia, with each of these projects at a different stage.

Current activity includes drilling the first well of the five well exploration drilling campaign at the Vecta project in Colorado, USA. The first well is expected to complete drilling in the next few days, to be followed by drilling of another four wells, each targeting a separate geological prospect in the area of Colorado where there is helium production, development, helium plants and a market for helium.

Mosman is also progressing the development of the Contingent Resources at its Sagebrush project in Colorado in which it has an 82.5% working interest.

Details of the Placing

The Company has raised £1,250,000 (before expenses) by way of a placing of 2,777,777,778 new ordinary shares of no-par value in the capital of the Company ("Placing Shares") through CMC Markets UK Plc ("CMC"), at 0.045p per share. As at 30 April 2025, the cash position was AUD 822,000.

The net funds from the Placing will be used for:

Andy Carroll, CEO of Mosman commented: "The evidence of helium at Sagebrush-1 means we have moved from exploration to development of this resource and this Placing supports the acceleration of this project.

"In addition, it provides additional funding to enable Mosman to be in a position to move on new opportunities, as demonstrated by the recent increase in our interest in the Billy Goat lease area from 20% to 90%."

Admission to AIM and Total Voting Rights

The Placing is conditional on, inter alia, the Placing Shares being admitted to trading on AIM. Application has been made to the London Stock Exchange for the Placing Shares, which will rank pari passu with the Company's existing issued ordinary shares, to be admitted to trading on AIM and dealings are expected to commence at 8:00 a.m. on or about 22 May 2025. A further announcement will be made regarding the Retail Offer.

Following the issue of the Placing Shares, the Company's total voting rights will comprise 22,314,854,996 Ordinary Shares of no par value and the Company does not hold any shares in treasury. Consequently, the above figure may be used by shareholders in the Company 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 share capital of the Company in accordance with the Companies' Articles.
