Phase 2 Initial Borehole Drilling and Testing, Ignace Area. WP3 Data Report – Geological and Geotech

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 WP3 activities, where it was received by the core logger. [...] The horizontal lines in each column in Figure 4 indicate the depths 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. [...] The broken structure frequency is generally highest in the upper 50 m of the borehole; however alternating zones of greater and lesser frequency persist along the length of the borehole. [...] 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 (WP5) (Golder, 2018b). [...] The final assessment of the dip and dip direction of natural, broken, fractures will be completed in association with analysis of the televiewer data (collected as part of WP5), for those fractures that are apparent in both the core and the televiewer data.
