Siren Gold Limited Annual Report 2020

Big River The Big River project (comprised of Exploration Permit 60448) is located ~15km southeast of Reefton. The project overlays the areas of the historic Big River Mine which produced ~136,000 oz of gold at an average gold recovery grade of ~34g/t between 1880 and 1942. The Big River mine is located on a NE trending anticline with the mineralised shoot developed along the fold hinge. A second anticline (A2) located 150m to the west has anomalous gold and arsenic soil geochemistry but has not been drilled. Mapping and Sampling Mapping and channel sampling of the A2 anticline has identified outcropping quartz reef up to 1m thick surrounded by sulphide rich sediments which contain lenses of massive sulphide in the footwall (Figure 7 and 8). Channel sampling indicate that the quartz reef is relatively low grade, but the footwall mineralisation assayed up to 11g/t Au. Figure 7. A2 quartz reef outcrop and channel samples results. Figure 8. A2 quartz reef between dotted white lines ~1m thick surrounded by sulphide rich sediments. Operations Review for the year ended 31 December 2020 Siren Gold Limited 10
