These examples should not be taken as limiting the broad meaning of sampling

• Include reference to measures takento ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

• Aspects of the determination of mineralisation thatare Material to the Public Report.

• In cases where'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as wherethere is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.

• Samples were accompanied by blank samples and duplicates.

Drilling Techniques

• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type,whether core is oriented and if so, by what method, etc.).

• Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.

• Whether sample compositing has been applied.

• Drilling was reconnaissance in nature and was broadly spaced, targeting specific structures

• Data spacing and distribution not sufficient to establish the degree of geological and grade continuity appropriate for mineral resources and ore reserve estimation

• No compositing has been applied.

Orientation of data in relation to geological structure

• Whether the orientation of sampling achieves unbiased sampling of possible structures andthe extent to which this is known, considering the deposit type.

• If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.

• Drilling is oriented to intercept known structures as close to right angle as possible.

Sample security

• The measures takento ensure sample security.

• Samples transferred directly to laboratory by field personnel in clearly marked bags.

• Sample numbers cross-checked with laboratory count.

Commentary

typical examples of such aggregations should be shown in detail.

• The assumptions used for any reporting of metal equivalent values should be clearly stated.

• No equivalent values used

Relationship between mineralisation widths and intercept lengths

• These relationships are particularly important in the reporting of Exploration Results.

• If the geometry of the mineralisation with respect to the drill hole angle is known, its natureshould be reported. If it is not known and only the down hole lengths arereported, there shouldbe a clear statement to this effect (e.g. 'down hole length, true width not known').

• Only down-hole widths quoted, no true widths known at this stage.

Diagrams

• Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery beingreported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

• Appropriate mapsand sections are included in previous announcements.

• Appropriate Plansand Maps included in the announcement

• Not all sections have been included as geological interpretation in the copper area has not been finalised.

Balanced Reporting

• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high gradesand/or widths should be practiced to avoid misleading reporting of Exploration Results.

• Drilling results have been comprehensively reported in this announcement. All information considered material to the reader's understanding of the Exploration Results and data has been reported.

Other substantive exploration data

• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.

• Exploration targeting has been enhanced by a structural study completed by Orefind in 2017, a ground magnetics study by Southern Geoscience in 2016 and a geophysical study completed by Baoding Geological Engineering Institute in 2011. The project is a target rich environment with 2019 planned exploration focussing on multiple targets. This has been further enhanced by a structural survey completed by Vaulin in 2022. A geophysical survey conducted in 2024 was also instrumental in targeting this drill program.

• No metallurgical test work hasbeen conducted on this drilling to date.

Further Work

• The nature andscale of plannedfurther work (e.g. testsfor lateral extensions or depth extensions or large-scale step- out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

• Ongoing diamonddrilling will be used to further define the nature and extent of the geochemical anomalism, and to gain lithological information.

• Most mineralisation is open bothalong strike and down/up dip.

• Further structural mapping, geophysical interpretation, trenching and drilling will be required to develop the resource model following the 2025 drilling.
