VMS staked a massive land position in 2006-2007, over the years they have done a lot of work on these claims and identified the most prospective areas for discovery. Mineral exploration lic's do not last forever and it would be expensive to keep such a massive package, you needed it years ago, its just common sense to stake everything when you don't know the wheat from the chaff, now that the initial exploration work is done you can save money by keeping the best and dropping the rest.
