· The 1 for 10 consolidation of the Company's shares.

· The change of name to Norseman Capital Limited (Norseman).

· A stock option plan.

· Mr Ballanger resigned from the Board to focus on his other businesses.

· Mr Sean Hurd was added to the Board. Sean is based in Vancouver and has considerable public company experience.

Mosman understands that the plan is now to revitalise GEM and complete a placing to give Norseman working capital to seek new projects and encourage a new investor base.

Mosman will from time to time review its shareholding in GEM with the intention that Mr Barr will step down from his current interim chief executive role within the next six months.
