The recent In3D Geoscience interpretative maps (see Figures 2 and 3) clearly identified numerous structural details associated with folding, with tight, plunging and linear limb features, several generations of faulting and intrusions likely transecting the older base metal and gold mineralization, moderate to deep continuity of the magnetic features associated with the known areas of mineralization shown particularly well at Relf Lake. Several additional patterns coincident with or along strike with 2002 EM anomalies, particularly along the northern zones north of the Nakina showings and west towards the Key Lake targets. Potential folding of said units, potential stacking and/or fold repetition of EM anomalies may be associated with the core of the Relf Lake target area and the Nakina 1 and 2 targets, and clarity of dextral (imbricate) offsets related to the strike breaks of known geochemical and geological anomalies among others.

Eagle Mapping LiDAR, Data Processing by GeoCloud Analytics

The LiDAR data is expected to complement the detailed geophysical interpretation recently completed by In3D Geoscience as outlined above, and currently available field geological data.

Eagle Mapping collected LiDAR data and aerial photography from the area, shown in Figures 1 and 2, at a nominal flight elevation of 5000 feet (1500 metres) at a minimum density of 8 ppm (pulses/m²) with expected accuracies of ±15 cm in the vertical and ±30 cm in the horizontal. Colour aerial photography will be orthorectified to the LiDAR base earth model with a 12 cm pixel resolution. Digital elevation (DEM) and digital surface (DSM) models with contours at 1 metre will be generated.

The LASer (LAS) point cloud with classified bare earth and metadata final report will be contained in the deliverables. The LAS format is an open binary file format designed for the interchange and archiving of LiDAR point cloud data and regarded as an industry standard for LiDAR data.

The Eagle Mapping aircraft mobilized from Thunder Bay, Ontario upon receipt of all requisite flight permits. The LiDAR surveys were completed on schedule during October 31^st, 2022. The final survey data are in processing and standard turnaround is estimated at two months.
