yml peer comparison : valuation

Help here would be appreciated. Did anyone notice on page 6 of YML's Investor presentation, the valuation comparison of YML compared to peers?

Key figures
EV/Resource (A$/t) Estimate 1.98
EV/Resource (A$/t) Wtd avg. (Iron ore juniors) 18.00

What does this say about YML's undervalaution?

What is YML's resource base used, and how is the peer valuaiton computed? Any ideas?

If this is true....well YML doesn't need any pumping from 'lil old me to move up, but OMG!
