I think we need more information on the huge grade adjustment factors RPM is applying to the grade.
"RPM considered it appropriate that the Mo and W grade adjustment factors should be applied. An adjustment factor of 114% for Mo and 144% for W above the 350m RL level and 144% for Mo and no change for W below the 350m RL."
If the problem is caused by coarse crystals wouldn't the larger 6" RC samples give a more representative result than half cut 63.5mm core. In which case the diamond hole grades should be downgraded.
Can the effect of the grade adjustment factor be quantified?
Despite the big scaling up factor why is it nearly all Indicated? Nearly all Indicated when 88% of the holes have been factored up ~50%...
It reads like this grade adjustment factor has been used before, have I missed this in previous announcements or is this the first time it's been reported?
Would like some one besides RPM (previously Runge) to have a look.
Not as happy as I was before. Someone, please tell me I'm wrong.
