they just keep drilling lines(grids) around where they found the high grade rock chips. its more luck than anything. they found a giant orebody already from the 1st set of drills. once they find an intersection, they just continue drilling the orebody/until the projection ends basically. They simply continue this grid like fashion all around the area to find repeat 'clusters' of spod. trial and error for spod. So far they havent found anything new yet, just infill drilling the initial discovery- hence the consolidation in the 1.50-1.60s area. There are some areas on the grid to the west of the initial discovery- they could prove additional 'clusters' once the results come back.
