While I do not discount your 'Conduit' theory, I say if we are going to get a multiple in the resource the chances are much better that it is not trough another conduit or horizontal extension of present.

The magma that brought the nickel comes from only one place - from below, and chances are that deeper we go the concentrations are likely to be more intense. Yes I mean a downward extension.
Why are they bringing in a deeper capable drill?
To test that idea.
And the reason they want to test it is because they already have an indication. Did they not say open at depth?
So if your idea pans out Herbert we are looking at a potential that you or I are not considering yet.
Cheers.
