The company would argue that the drilling adds value because it allows them to better define the high grade zones.
As to whether it actually adds any value (to the resource) will depend on whether they have intersected more high grade mineralisation in this 10m spaced drilling than was evident in the already existing 20m spaced drill sections.
My quick look (at the limited 2010 results) suggests what they announced this week was pretty much the same as what they intersected before.
10m spaced drilling is very tight a cynic would say the drilling was done with a raise in mind.
