("Mosman" or the "Company") 

Vecta Project Update

Further to the Company's announcement on 20 May 2025, Mosman Oil and Gas Limited (AIM:MSMN) the helium, hydrogen and hydrocarbon exploration, development and production company, announces an update on the Vecta Project in Colorado, US.

Mosman, Vecta Oil and Gas Ltd ("Vecta") and Desert Eagle Operating LLC ("Desert Eagle" or "DE") have reached a tripartite agreement regarding commercial arrangements on the Billy Goat Area of Mutual Interest lease area ("Billy Goat") that is summarised as follows:

This Agreement does not impact the Company's 20% working interest in the remaining Vecta Project AMI areas called "The Bard", "Garcia", "Treasure Hill" and "Mona Loa".

The drilling rig crew will be on a short break after completing operations on the first well, Barclay-TH 295 106A, and will return on 2 June, when further drilling on the wider Vecta Project will commence. The next drill location on the Vecta Project is expected to be the "The Bard" which is adjacent to Billy Goat.

Billy Goat is now the property of the working interest parties being Desert Eagle and Vecta and any data is considered commercially confidential.

Carrying value of asset in Mosman's balance sheet is US$200,000 and there are no profits or losses attributable to Mosman's existing working interest in Billy Goat.

Andy Carroll, Chief Executive Officer of Mosman, said: "This arrangement with Desert Eagle is the best way for Mosman to commercialise our interest in the Billy Goat asset. Desert Eagle and associated companies are the leading helium drilling, development, production and marketing group in this area of Colorado with a proven track record of delivery.

"The 5% overriding royalty interest provides the opportunity for Mosman to share in revenues from the Billy Goat AMI lease without capital investment in drilling and development, and without ongoing production operating costs.

"This allows Mosman to allocate capital to explore further opportunities in the drilling of other wells in the wider Vecta Project and in the development of Sagebrush where helium is proven having been tested in an existing well with access to nearby production infrastructure.

"We look forward to further drilling on the multiple wells in the wider Vecta Project once the drilling rig crew returns on 2 June."
