Geophysical-based RQD mapping (generated by the software SKUA-GOCAD (Version: 22 build 2022.06.20)) at different depths, including (a) RQD distribution at 0, 200, 600, 1000, and 1300 m depths (RQD on a color scale increasing from dark red to dark blue), and (b) Analysis of RQD at 0, 200, 600, 1000, and 1300 m depths for four faults (F1–F4), fresh granite (FG), hornstone (HS), poorly weathered/fractured granite (PW/FG), sandstone (SS), and moderately weathered/fractured granite (MW/FG).
