The cut-off grade is a mining project's break even grade. You estimate cut-off grade by knowing the OPEX or day to day operating expense. I'm sure by looking at other operations in the area they have got the OPEX close and the cut-off grade right.

"The cut-off grade used in the Van Dyke resource estimate is consistent with that used in resource estimates on other similar oxide copper projects in Arizona."

Theres several other, almost exact operations to the mining scenario and metallurgical recovery process they propose for Van Dyke in the area.
