can you value nst?

Hi guys/gals,

I've never tried to value a gold coy like NST nor would I know how to start. I assume it would involve adding bullion and cash and reserves and plant & equipment and debt etc ...then dividing by the number of stocks and options on issue? How did you figure in... inferred resources vs measured? I would imagine inferred is what traders bake into a stock to give it a value above it's current measureable value as a company?

Anybody with greater knowledge than myself want to give it a whack with NST and educate the rest of us? :)

Thanks in advance!

Cheers
