My calculations acknowledge that the likely best bits have been drilled first or cherry picked. And why wouldn't you. Geologists are like magpies, they'll pick the juiciest bit first. Only the Northern Mineralised Zone Block A has been drilled with an average grade of 1850ppm across the block. The spreadsheet shows this.

Block A is also the only part of Big Sandy that is relatively flat lying and was relatively easy for the RAB drill crew and was drilled first as much for this reason as any other. The drone footage video illustrates this. I'm expecting the rest of Block A to have similar grades or better - as the video footage clearly looks better with the green colouring more evident.
