I agree with you explorationguy. We know there are hits on most of those holes; only the last few have been unreported. Sloppy posting work is the most likely explanation.
As I've mentioned before, the web page has not been kept up. It wouldn't take much effort to do so; I guess nobody has been given that task at head office.
I can only hope (and I'm REALLY stretching it here) that the reason is they want to put ALL their financial resources into competant geologists and so have none left over for competant IT people.
