Just by way of a follow up to my previous post regarding the relationship between total sulphide and the Nickel grade, the image below describes the point I was making from the research I've done.
The text accompanying the diagram is as follows:
"Since the conductivity probe detects total sulphide, it is essential that a relationship between total sulphide and nickel grade exist in order for nickel grade estimation to be accurate. When the deposit is dominated by pyrrhotite, the total sulphide plot shown in Figure 4 is essentially a plot of pyrrhotite versus nickel, with the slope defining the pyrrhotite:nickel ratio"

So what they're basically saying is that form their experience if the ore body is DOMINATED by pyrrhotite, the graph shown above was used to reliably estimate the nickel grade.
--
Lets hope that this ore is not utterly dominated by pyrrhotite and that that we see a greater proportion of pentlandite.
--
There are others who know more than me and I do appreciate that the Po:Pn ratio is variable both within a hole let alone the ore body, but hey this may help others with their research.

I have emailed the company asking for the total pyrrhotite (Po) percentage they observed from previous drilling where they got 97m @ 0.17% Ni.
If you're curious you can look up the compsiotn by weight of Pentlandite (mindat.org - if i recall) and you'll see that it is 34% Ni. So they got those last results from just 0.51% Pentlandite.
Quesiotn is how much Pyrrhotite was there?
