res fe % cut off ???

Hi guys, its keeps ticking away at me,

Why with the 2 phase of drill results Res was 1.6bil tonne @30.2 Fe,the (cut off Fe 25%).OR
2.26bil tonne @ 27.6% Fe, (15% Fe cut off),

Now 1st Jorc was fro 617mil tonne, @ 32 Fe%, and using a (15% cut off grade)

Ok my question, is the 30.2Fe, is it so revevant compared to 27.6Fe, if so i can see why Lcy have then used different cut off grades.

Or are we being fed info in a different format.

I really thought the cut off grades determine quanity in a big way, so why is the 2nd phase of drill results fed to us at different cut off rates to the 1st lot.

i can only presume its to get as close to the 30.2 fe%, if this is so,then the quality of the Rescourse @ 27.6% is not good enough.

Why else, because this way of Ann's loose us 616mil tonne, just by doing the cut off's different ????

Please entilghrn me, it has been at me for ages, i asked this question about 6wks ago, didnt get an answer, please HELP me out.

cheers
