I think both AEM and LSG are waiting untill the chromite is monitized and drilling on Borden and the alteration continue.

When prb has advanced a little further and the chromite is out of the market cap they may strike at PRB. There would be little risk at that time to making a move on PRB... right now they would be monitizing the chromite if they made a move on PRB and besides it's a little premature.

Like Cliffs they want to see results that prove they are making a potential gold resource... not pie in the sky.

That being said I also bought a few more today and have my stink bids in just in case some get an itchy finger.
