Appointment of Chief Executive Officer and Board Update

Mosman Oil and Gas Limited (AIM: MSMN), advancing helium, hydrogen and
hydrocarbon projects in the USA, is pleased to announce the appointment of
Howard McLaughlin as Chief Executive Officer (non-board).

In addition, Carl Dumbrell, currently Chairman, will now serve as Executive
Chairman, and Andrew Scott, currently Non-Executive Director, will take on the
role of Executive Director.

Appointment of Chief Executive Officer

Howard McLaughlin has been with Mosman since 2017 as Manager of US Operations,
overseeing field activity and project development. He was instrumental in
Mosman's strategic move into the helium sector in North America, introducing
both the Sagebrush and Coyote Wash Helium Projects in Colorado.

Howard has a strong personal alignment with shareholders through his direct
investment in Sagebrush, providing clear motivation to see the project
successfully developed. He has served as Interim CEO since June 2025 and now
formally steps into the CEO role.

Howard brings decades of technical, operational and commercial expertise,
having spent 19 years at BHP Petroleum, ultimately serving as Vice President
of Global Exploration. He is also a former Managing Director and CEO of an
ASX-listed public company, with extensive international experience across
Australia, Europe, Africa, the Middle East, Asia and North America.

Carl Dumbrell, Executive Chairman of Mosman, commented: "We are delighted that
Howard has agreed to become Mosman's CEO. His personal investment in Sagebrush
and his long-standing commitment to Mosman since 2017 make him the ideal
person to lead the Company. Over the coming months we will reach important
milestones, including the start of 3D seismic over Sagebrush in October and
the extended well test on Sagebrush-1 in Q4. Together with progress at Coyote
Wash, these steps mark the beginning of an exciting new chapter for Mosman.
With an independently verified helium resource and a clear pathway to
development, the Company is well positioned for future value creation and we
move forward with confidence."
