Phase 2 Initial Borehole Drilling and Testing, Ignace Area. WP03 Data Report – Geological and Geotec

After the core was retrieved from the borehole by the drillers and extracted from the core tube, the run of core was carried by the drillers in a split tube to the core logging trailer for WP03 activities, where it was received by the core logger. [...] The horizontal lines in each column in 10 September 29, 2020 1671632 (2301) Figure 4 indicate the depths along the borehole of the logged contacts for each rock unit occurrence, except for the predominant biotite tonalite unit which was logged along the majority of the length of the borehole and is represented by the pink shading in the leftmost column in Figure 4. [...] This alteration is characterized by a grey discoloration of the rock mass and associated reduction in the clarity of the grain boundaries of the biotite tonalite (Figure 8c). [...] A subsequent step in the analysis of structures involves the integration of the core logged structures with those structures interpreted from the analysis of optical and acoustic televiewer datasets collected as part of the geophysical logging activity (WP05) (Golder, 2020b). [...] A compilation of the distribution of broken and lost core zones, and ductile and brittle structures along the length of the borehole is shown in Figure 11.
