The reported grades should be used in every instance.
The danger is that the equivalent grades can be maniculated so that they can appear to increase the grade component of a metal so that this metal then appears that it could be economic, then it fact it won't be.
I am not sure why we should be comparing SIR which have a Ni disovery to KDR which has other metals. Geology and potential is much different as well?
If all recovery factors are known over the distribution of the deposit then I would feel more confident of using an equiavlent grade. Let's say someone has 100 g/t silver then I would say that maybe 50 to 70% could be recovered. At this stage trying to use an equivalent garde could be seen as being desceptive.
If you the shareholder attempts to use this data and come unstuck then who do you blame if you later get a surprise when you find out that the figures have been ajusted to reflect the recoveries.
