I'm a bit behind with my reading so let me try to answer about this one paragraph as I understand it:
<
Perhaps someone could help me with this one. The 178.84 meters of mineralization is contiguous with another 37.47 meters right above it. This first section was reported separately as 1.77m of massives from 269.21m to 270.98m, and 35.70m of disseminated sulphides from 270.98m to 306.68m. Starting from there the "main" zone is reported as 178.84m of 1.19% Ni, etc. Why on earth would they report it this way? It makes no sense to me. 216.31m of mineralization sounds way better! The overall grade would only drop from 1.19% Ni to 1.10%. Any explanations? Is this spin? Just a little confused here.>

By example:
Small residential apartment building with three floors,
Floor one (street level) has three apartments, remainder offices etc.
Floor two has five apartments.
Third floor has one - A Penthouse.
But the Average Floor for the bulding has three appartments.

So it is with mineral deposits. They are NEVER homogenious.
To describe them, a report will give an average for the whole thing but on occasion will highlight low and most often high concentrations to give one an idea of the deposit's distribution.

With the 216 meter B interval they first divided it into three sections similar to my apartment example.
This shows that the first two meters have a high (over 5%) nickel content (8 grams of silver not impressive, imo.).
The second has low nickel but good palladium content.
And the last and largest has adequate nickel content high palladium.
The "AND"s following break it down further, but you should get the general idea.
No spin, that is how most reporting is done.
Also , That is how I prefer to see it.
Cheers.
