Notes to editors

Mosman (AIM: MSMN) is a helium, hydrogen, and hydrocarbon exploration, development and production company with projects in the US and Australia.

Mosman's strategic objectives remain consistent: to identify opportunities which will provide operating cash flow and have development upside whilst maximising the opportunity for further production growth and increasing cashflow from its current US projects.

Mosman has two exploration areas in the Amadeus Basin in Central Australia which are well positioned to take advantage of the increasing demand for Helium and Hydrogen, in addition to oil and gas. Mosman recently acquired an interest in helium exploration in Colorado, USA.
