Plan view showing 2020 infill drilling collars over 2017 indicated and inferred resource outlines
Shows the location of the 223 holes (yellow dots) that were drilled in the 2020 infill program, predominantly within the Inferred Resources areas (shown in blue) of the 2017 resource estimate.
Cross-section Line 8.25 showing distribution of average grade blocks and geology
3D perspective view of 2021 indicated and inferred resource estimate blocks
Cross-section in the northern area of the 2021 Paris Silver Project Mineral Resource estimate at Line 8.25, looking north, showing the distribution of the average grade blocks (+/- 12.5m section window). The background colours indicate the geological setting.
Cross-section Line 0.5 with 2020 assay intervals and geology
Cross-section along Line 0.5, looking northwest, showing the holes drilled in the 2020 infill program (red labels on collars) and the limited previous drilling (+/- 12.5m section window). Holes are shown as grey traces with red indicating the location of assays above 30g/t silver. Intersections above 100g/t silver are noted in yellow “call-out” boxes. Intersections above 30g/t silver are noted in white “call-out” boxes.
