John W Barr, Chairman, said: "The current pandemic and the oil price fluctuations have all resulted in Mosman and the Operator of projects focusing their attention and operations on cashflow and costs rather than maximizing production. This together with Stanley-1 being offline, has of course led to production levels falling for the period.

"As recently announced the focus is now returning to production with two workovers and two new wells planned and now financed.

"Mosman is determined to continue to build its production base and is encouraged by the solid asset position it has established, combined with exploration potential."
