Alexander River Mapping and Geochemical Sampling The Alexander River Project (Exploration Permit 60446) is located ~26kms southeast of Reefton, in a mostly fault‑bounded sliver of Greenland Group rocks 7kms southeast of the main Reefton Goldfield block. It is bounded by undeformed granite to the west, and by a metamorphic core complex to the east. The Alexander mineralisation outcrops for over 1.2kms (Figure 6) and is comprised of high-grade quartz reefs and disseminated mineralisation. Surface trenching and channel sampling show that the mineralisation ranges from 2-15m thick, with an average thickness and grade of 4m@ 8g/t Au. Surface sampling identified four mineralised shoots, named Bull, McVicar, Bruno and Loftus-McKay. Only the McVicar East Shoot was mined to any extent, with the shallow plunging shoot mined to 250m below surface, extracting 41koz at an average recovered grade of 26g/t Au before the mine closed in 1942. Structural mapping has confirmed that the Alexander River mineralised zone can be divided into two structural domains. The Bull-McVicar-Bruno reef track is ENE striking, steeply SE dipping, while the Loftus-McKay reef track extends fromBruno into Mullocky Creek and is NNE-striking and dips 50o to the NW. In both structural domains, it appears that the intersection between an anticline hinge and a mineralised fault likely controls the trend and plunge of Au‑bearing shoots. The arsenic soil anomaly extends fromBull and ends around the last known outcrop of the Loftus-McKay Shoot near Pad 28, where the shoot is interpreted to be offset approximately 150m to the north by a NNW trending Mullocky Fault (Figure 6). This interpretation is based on the offset of a dolerite dyke and the absence of the Loftus-McKay Shoot in holes drilled from the next two pads to the north. Diamond Drilling Siren has now completed 107 diamond drillholes for 20,323m at Alexander River since drilling commenced in October 2020. 35 holes for 10,108mwere completed in 2022. A plan and a long section of the drill hole locations is shown in Figures 6 and 7. The mineralised shoots have been traced for up to 1.3kms down plunge until they have been offset by a fault (Figure 7). Drilling on the NE side of the fault has intersected a number of dolerite dykes that have also been mapped on the surface (Figure 6) and by a recent drome magnetic survey. These dykes postdate and have removed the mineralisation over an estimated 100m strike. It is expected that the mineralised shoots will extend to the north beyond the dykes and this area will be targeted when drilling recommences.
