Forward Looking Statement 2 aureka.com.au ASX:AKA | Exploration Target On 30 March, 2021, Navarre Minerals Limited ASX:NML announced the maiden gold Exploration Target at its flagship 100%-owned Irvine Gold Project in Victoria, Australia. Notably, the Exploration Target was constrained to the current drill footprint at the Resolution and Adventure lodes, as at the time these areas only contained sufficient drilling to determine continuity and infer grade ranges. The Navarre portfolio was purchased and rebranded by the Aureka team in 2024. Significant potential exists to increase the size of the exploration target with additional drill results beyond the Exploration Target area. On 26 May 2025, Aureka (ASX.AKA), announced an updated Exploration Target total to include for historic drilling at St Arnaud, yielding a maiden JORC resource and Exploration Target. The potential quantity and grade of the Exploration Target is conceptual in nature and therefore is an approximation. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The Exploration Target has been prepared and reported in accordance with the 2012 edition of the JORC Code. Summary of Relevant Exploration Data, Methodology, and Assumptions Previously engaged consultants had, in conjunction with Company personnel generated an estimate of the Exploration Target for the Resolution and Adventure prospects. These Exploration Targets represent the strike and depth/plunge extensions to the Mineral Resources defined for both deposits. The results of this estimation are presented in Table 1 for the combined Exploration Targets. The Resolution and Adventure prospects are intersected by a predominantly west dipping shear zone which broadly mimics the strike of the Irvine basalt dome. Gold occurs on or adjacent to the shear zone, typically on meta-basalt/meta-sediment contacts where the rheological contrast provides an ideal locale for shearing and mineralisation. The attitude of the contacts also influences the shear geometry resulting in localised, high-grade gold shoots. The Exploration Target was based on the interpretation of the following geology and mineralisation data that had been collated as part of the 2021 MRE statement: ▪ 42 structurally oriented diamond drillholes and169 aircore, drill holes for a total of 23,465 m at the Resolution prospect that have been drilled by Navarre Minerals (NML), ▪ 10 structurally oriented diamond drillholes and 195 aircore, drill holes for a total of 17,952 m at the Resolution prospect that have been drilled by Navarre Minerals (NML), ▪ 943 density measurements on mineralised diamond drill core, and the determined SG’s were applied to the appropriate lithological units involved with the Exploration Target, ▪ surface geological mapping, costean data and diamond core geological logging, ▪ detailed LiDAR imagery, ▪ geophysical datasets including detailed ground magnetic and 3D induced polarisation, and ▪ wireframing and modelling of the Resolution and Adventure mineralised bodies. For the Resolution prospect, the Exploration Target has been estimated based on the strike continuity and down plunge continuity of the mineralisation defined by drilling and modelled as part of the Mineral Resources. The extent of this strike and plunge continuity is considered to be consistent with that evident in the Magdala deposit analogue to the north of Resolution, as the mineralisation controls and style are consistent between the two deposits. To determine the tonnage and grade ranges for the Resolution prospect Exploration Target, the existing Mineral Resources as defined at Resolution was used as the base case in combination with the geological understanding of the mineralisation model for Resolution. The northern strike extents component of the Exploration Target has been based on the initial wide spaced shallow AC drilling that extends approximately 900 metres to the north of the defined Resolution mineralisation. The Consultants determined that the potential for a repeat of the mineralisation defined in the upper parts of Resolution along strike is adequate for estimating an Exploration Target that is within +/-20% of the Resolution open pit Mineral Resource. In addition, the strong southerly plunge controls evident with the deeper parts of the Resolution Mineral Resource have been used to guide the estimation of an Exploration Target down this plunge direction at depth. This part of the Exploration Target has used the UG Mineral Resource defined at an MSO cut-off grade of 1.4 g/t Au as a base with a +/-20% range applied for the tonnage, grade and ounces. For the Adventure prospect, the Exploration Target has been estimated based on the wide spaced exploration drilling that has been completed to date. The mineralisation as defined by these drill results does not currently have adequate confidence to be classified as a Mineral Resource. However, Mining Plus considers that the estimation of an Exploration Target is possible for the mineralised extents that have been modelled. The ranges for tonnage, grade and ounces have been estimated using the Adventure block model results reported at a 1 g/t Au cut-off (Figure 10) for those estimated blocks remaining unclassified (that do not satisfy the criteria of an Inferred Mineral Resource). A -20% and +30% range has then been applied to determine the ranges required for reporting an Exploration Target*. It is important to note that as these estimated blocks do not meet the requirements of a Mineral Resource, there is increased likelihood of grade extrapolation, rather than interpolation, hence the application of suitable tonnage, grade and ounce ranges for the Adventure Prospect Exploration Target. The upper grade, tonnage and ounces range of +30% has been based on the presence of two of the higher grade and thicker intercepts returned to date for Adventure being located at the base of the Exploration Target.
