 ("Mosman" or the "Company")

Falcon update

Mosman Oil and Gas Limited (AIM: MSMN) the oil exploration, development, and production company, announces an update on its Falcon-1 well at the Champion Project in Texas.

The drilling rig for Falcon-1 has been selected and the Operator has issued the cash call for the well drilling costs to participants, including Mosman, which the Company will pay shortly from existing funds. The drilling rig is being prepared for mobilisation to site with drilling planned once the rig is on-site and rigged up.

As part of its ongoing project evaluation, Mosman has reduced exposure to costs by farming out 10% of its working interest in the Champion Lease to an unrelated third party. That party will pay 13.34% of all costs of the site preparation, drilling and completion of Falcon-1 to earn a 10% interest in the lease.

John W Barr, Chairman, said: "We are pleased that the considerable work completed means drilling activity at the fully funded Falcon-1 well will commence shortly.

"Falcon-1 is just one part of the current activities with workovers, which will shortly be followed by a second funded well at Stanley. Each of these activities has a clear objective to build the production base."
