Spotted on the Crown Minerals site: GEL has today been granted the discovery appraisal extension on EP40667 for Muirs. It will last until 3rd October 2013. This is for 595Ha, encompassing the main Muirs site, which is already covered. I'm still in the dark about what a discovery appraisal means, but I think it's a step up as far as findings go, from a standard EP.
