Sampling techniques

• Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
• Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
• Aspects of the determination of mineralisation that are 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 where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information

• Earth AI Pty Ltd (Earth AI) is the current operator of the Cundumbul project (EL6661) having entered an Exploration Alliance Agreement in October 2022 (October 6th, 2022 press release "Alliance with Artificial Intelligence Explorer for Cundumbul project")
• Kincora Copper Limited (Kincora) has reviewed the historical exploration activities and results for the purposes of JORC and NI 43-101 reporting purposes.
• The operator of the Cundumbul project during the last phase of exploration and drilling activities was Clancy Exploration Limited (now RareX Limited) with joint venture partner Mitsubishi Materials Corporation.

Rock sampling program:

• All rock sample site locations were traversed using a single point GPS receiver.
• All rock chip samples were taken in the field by the previous explorer during the field activities and mapping program.
• Rock samples were collected from surface outcrop and float.
• Samples weighing up to several kilograms were collected.

Soil sampling program:

• All soil sample site locations were traversed using a single point GPS receiver.
• One 'B' horizon sample was taken at each location.
• A hand auger was used to obtain a 250 gram sample, which was sieved to achieve a <3mm 'fine' fraction.
• The 250m x 250m grid was completed in regional soil sampling program and XRF analysis of all samples was carried out by previous explorer staff using the Innov-X Delta Handheld XRF Analyser in a static test bench/workstation setup.
• The infill soil sampling program at the Mehruda Mine and Mehruda Big Hill prospect areas on a 50m x 50m grid was also conducted with laboratory analysis.

Drilling program:

• Historic mechanical auger drilling, RC and diamond core drilling was conducted in Cundumbul project.
• One bulk sample (1-2kg) was taken from the bottom of each auger drilling hole.
• Two metre composite samples were taken from the RC drilling.
• One metre half-core samples were taken from the diamond drilling.

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.).

• Historic drilling on Kincora projects and at the Cundumbul project by prior explorers used a variety of methods including mechanical auger drilling, reverse circulation, and diamond core. No Kincora or Earth AI drilling has yet taken place at the Cundumbul project.
• Mechanical auger basement sampling program was completed at the Andrews, Bakers Swamp, Gowan Green, Mehruda and Mehruda Mo Anomaly prospects. They were drilled at 75m spacing along 200m spaced NE-SW orientated lines, with an average refusal depth of 2.4m.

• Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.

• Drill Core recovery wasn't logged in diamond drilling.
• Samples were bagged as separate 1 metre intervals. Visual checks on sample sizes assisted with determining sufficient recoveries and alert to sample mixing. Minimal water injection was used to lubricate the samples.

Logging

• Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
• Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography.

Mineral tenement and land tenure status

• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
• The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

• Kincora holds four exploration licences in NSW and rights to a further six exploration licences through an agreement with RareX Limited (RareX).
• EL8222 (Trundle), EL6552 (Fairholme), EL6915 (Fairholme – Manna), EL8502 (Jemalong), EL6661 (Cundumbul) and EL7748 (Condobolin) are in a JV with RareX where Kincora has a 65% interest in the respective 6 licenses and is the operator /sole funder of all further exploration until a positive scoping study or preliminary economic assessment ("PEA") on a project by project basis. Upon completion of PEA, a joint venture will be formed with standard funding/dilution and right of first refusal on transfers.
• The Exploration Alliance with Earth AI relates to EL6661 (Cundumbul) only and allows for a co-funding model and joint technical committee, whereby Earth AI will have day-to-day management and control of exploration activities, and contribute up to A$4.5m of total exploration expenditure across the project over a two-year period with an option to extend for a further year.
• Subject to a minimum of 1500 metres of diamond drilling and a Qualifying Drilling Intersection resulting in a new discovery (as defined within the Exploration Alliance Agreement), Earth AI is entitled to a net smelter return royalty (Royalty) of up to 3% in connection with a to be agreed upon area surrounding the discovery (Area of Interest, size dependent on the extent of the newly discovered mineral system).
• Kincora is under no obligation to explore, develop or mine the Cundumbul project during the period of the Exploration Alliance. However, upon Earth AI successfully drilling a Qualifying Drilling Intersection and having carried out a minimum of 1,500 metres of diamond drilling, whereafter the second anniversary of the Royalty Trigger Date if no mineral resource has been defined and the annual exploration expenditure in the Area of Interest falls below US$250,000, Earth AI will have the option to assume operational control and buy all of the Royalty Tenements that overlap with the Area of Interest under the Royalty Deed, for a cash purchase price equal to US$1,000,000 plus a 2% net smelter.
• The Agreement will not affect the capital structure of the Company or current ownership in the project, with Kincora and RareX Limited (REE:ASX) retaining the existing 65% and 35% respective interests in the Cundumbul project/license. Rights of first refusal customary for such an ownership and Exploration Alliance structure are in place.
• EL8929 (Nyngan), EL8960 (Nevertire), EL9320 (Mulla) and EL9340 (Condobolin East) are wholly owned by Kincora.
• All licences are in good standing and there are no known impediments to obtaining a licence to operate.

Exploration done by other parties

• Acknowledgment and appraisal of exploration by other parties.

• All Kincora projects have had previous exploration work undertaken by other explorers. The review and verification process for the information disclosed herein and of other parties for the Cundumbul project has included the receipt of all material exploration data, results and sampling procedures of previous operators and review of such information by Kincora's geological staff using standard verification procedures. Further details of exploration efforts and data of other parties are providing in the March 1st, 2021, Independent Technical Report included in the ASX listing prospectus, which is available at: https://www.kincoracopper.com/investors/asx-prospectus
• Earth AI in April 2023 commenced field work at Cundumbul project under Exploration Alliance Agreement to conduct and jointly fund certain exploration activities on the tenement area.

Geology

• Deposit type, geological setting and style of mineralisation.

• The Cundumbul project is located in the Molong belt of the Macquarie Arc, 30km south of Alkane's Boda-Kaiser porphyry projects (maiden resources >14.8Moz AuEq), 25km north of the Copper Hill project (>3Moz AuEq resource) and 70km north of the Cadia mine and series of porphyry deposits (>90Moz AuEq endowment).
• The projects' geology comprises north-striking fault-bounded slices of Ordovician, Silurian, and Devonian age rocks. Bounding structures are regionally extensive, east-dipping and west-verging thrust faults. One of these thrusts, the Neurea Fault, lies along the western edge of the project and emplaced intermediate volcanics and sediments of the mid-late Ordovician age Oakdale Formation in the east over early Ordovician sediments to the west.
• Units within the Oakdale formation have been distinguished from detailed mapping and magnetics. Four stratigraphic units are recognised):
• i. Massive basaltic andesitic volcanolithic conglomerate –debris flow deposits.
• ii. Interbedded siltstone and fine to medium-grained volcanic sandstone with minor pebble conglomerate: turbidite deposits.
• iii. Massive polymictic volcanolithic cobble conglomerate, intermediate lavas and allochthonous limestone –debris flow deposits.
• iv. An upper siltstone and fine to medium-grained volcanolithic sandstone –turbidite deposits distinguished by a high K radiometric response.
• Historic exploration, through mapping and limited drilling, has defined intrusive rocks associated with mineralised prospects, including monzonite, monzonite porphyry, quartz monzodiorite and granodiorite.
• Greenfield exploration to date has led to confirmation of a Late Ordovician stratigraphic setting, the presence of porphyritic intrusives and the discovery of high-grade molybdenum, silicification and sulfide veining in a highly faulted setting at the Bell target. There are similar anomalies along the apparent N-S structures to Bell. SRK identified 30 prospective targets across the license, particularly in the north of the license, including the Andrew's target.

Drill hole Information

• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
• easting and northing of the drill hole collar
• elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
• dip and azimuth of the hole
• down hole length and interception depth
• hole length.
• If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

Mining Associates has completed an review of prior drilling activities at Cundumbul dated February 25th, 2021, as outlined in the Independent Technical Report included in the ASX listing prospectus (dated March 1st, 2021), which is available at:

• https://www.kincoracopper.com/investors/asx-prospectus

Data aggregation methods

• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.
• Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
• The assumptions used for any reporting of metal equivalent values should be clearly stated.

• All reported assays have been length-weighted. All intervals are calculated with a 100ppm Mo, 500ppm Mo, 0.1% Mo or 0.1g/t Au cut-off. No upper cut-offs have been applied.
• Intercepts are length-weighted with no cutting of grades. This may lead to elevation of intercept grades due to the presence of a narrow interval of high grade material. Such high grade zones are reported as included intercepts inside the broader intercept.

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 nature should be reported.
• If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').

• Due to the uncertainty of mineralisation orientation, the true width of mineralisation is not known at Cundumbul.
• Intercepts from historic drilling reported at other projects are also of unknown true width.

Diagrams

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

• Relevant diagrams are included in the body of the report.

Balanced reporting

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

• Intercepts reported for prior drilling at Cundumbul are zones of higher grade within unmineralized or weakly anomalous material.

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.

• No other exploration data is considered material to the reporting of results at Cundumbul. Other data of interest to further exploration targeting is included in the body of the report and in Mining Associates Independent Technical Report included in Kincora's ASX listing prospectus (dated March 1st, 2021).

Further work

• The nature and scale of planned further work (e.g. tests for 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.

• Ground truthing field work commenced in April 2023 by Earth AI to confirm and refine drill targets at the Cundumbul project with drilling planned in the next quarter.
• o Earth AI's work is under the existing success based exploration alliance that seeks to leverage Earth AI's vertically integrated, proprietary artificial intelligence and machine learning capacity to generate, fund and drill test targets.
• o Earth AI's exploration at the Cundumbul project is in addition to Kincora's ongoing drilling program seeking to drill test a total of 13 copper-gold discovery opportunities across 5 projects in the Lachlan Fold Belt
