jorc resources

can someone(may be long term holders) please direct/show me a good website to better understand what all the inferred/indicate/measured stuff means.also the cut off grades? Or may be explain it in simple terms.

do they have to do scoping study 1st and then the feasibility study? Iwas trying to read langer H (paladin) history. but still cant quite get it. i wonder whether i have done my "research" right

what's the time frame normally to get all of these done?

i had a look at www.cameco.com, uranium fuel cycle .It is interesting and educational but, fairly basic.

thanks in advance
