Cup and Handle Formation, page-107

The SO4 drill campaign intercepted the key basal sands twice in 27 holes. No mention of depth or grade.

The GPH campaign has intercepted the basal sands in all but one. They've also intercepted decent grades and widths in an upper sand layer not anticipated in the resource estimate.

Add the two sand layers together and you have 20 - 50m of highly porous sands   with good grades in nearly each hole.

We have also consistently drilled to depths between 100 - 170m compared with SO4's average of ~60m.
