I doubt it has any great bearing on the recent land grabs, but effective July 1, 2012 the Mineral Tenure Act amendments call for an increase in certain fees. I can't see this being a huge deal for Teck and their deep pockts, but then again, why not stake some large claims now that you are considering anyway and save some $ at the same time? Get in now and beat the rush.

Or maybe they have a good idea of what the reRE will show and want to stake off the territory early before too many get wind of it.

See the Schedule B at the end for fee changes, and other changes highlighed throughout:

E.g. Registration of mineral cell claims and placer cell claims going from $0.40 to $1.75/hectare and $2 to $5/hectare respectively.

Mining lease annual rental per hectare going from $10 to $20 and placer lease annual rental per hectare going from $5 to $20.
