As you know core drilling costs a hell of a lot more than RC so every company will use it sparingly. The geos at Rocklands have more faith in core drilling because of the native copper as has been explained. The core drilling is a better representation of what this resource holds and you will find that the grades should be higher. The company has explained the results of the core drilling aren't a true value of what they believe because of the analytical methods that need to be used for JORC requirements. The results from the bulk sample should be higher than the core samples because of this but can't be used to define the resource. Core samples represent 22.5% of the resource and the bulk sample represent 7.5% of the core samples. Using that information you decided if the JORC of 31 Mt is a true representation of the resource.
