I do not know about Sage but I have heard that when a company makes that decision [which can run into a large drill expense] they do so because what was previously discovered by them or others before them warranted the special attention.
The down hole probe will enable them to 'see' for 200m around in a 360 degree circle. I think you get the best IP results within the first 100m.
Sounds like they strongly suspect that they are going to be successful in the hunt.
All the best guys/gals,
