14 Impact Minerals Ltd Annual Report 2022 Figure 2.3: Additive Z scores for all REE across the Jumbo-Arkun project area. Seven priority areas for follow up work are highlighted including three new areas at Jumbo. Note that there several other areas with strong responses within the Jumbo project which will also require follow-up work. Figure 2.4: Rubidium assay values across the Jumbo-Arkun project area. The Jumbo project stands out as a very elevated area for rubidium compared to most of the Arkun project. This may reflect a higher background for rubidium in this area and therefore may be more prospective for this valuable alkali metal. New targets have been identified at Jumbo as follows: Nickel-copper-Platinum Group Elements-Gold (Figure 2.1): three new priority targets identified. The eastern most target has a significant gold-dominant response, and which covers an area of several hundred metres across trend. Lithium-caesium-tantalum (Figure 2.2): two new priority targets identified with several lower priority areas also warranting follow up. The two priority targets are at least a few hundred metres wide. Rare Earth Elements (Figure 2.3): three new priority targets identified with numerous other lower priority areas also warranting follow up. Rubidium (Figure 2.4): the entire soil geochemistry traverse stands out as being elevated in rubidium, in particular in comparison with Arkun. The large area covered by elevated REE and rubidium results suggests that the Jumbo area may be underlain by extensive areas of granitoid and pegmatite rocks that are enriched in these metals compared to Arkun. This is encouraging for future exploration. First pass follow-up field checking, and sampling will start in 2023 with the aim of prioritising areas for more detailed soil geochemistry and ground geophysics. Land access agreements will be required with relevant landowners and this process will also be commenced. Review of Operations continued
