Article content

Criteria	JORC Code explanation	Commentary
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 (e.g., submarine nodules) may warrant disclosure of detailed information.	Balla Balla AC samples were speared from 1 m sample piles into 3 m composites. Composite length was reduced at end of hole to accommodate a final one metre end of hole sample. Samples are approximately 2 – 3 kg, and pulverised in full Speared composite samples were analysed for gold using a 50 g fire assay. End of hole samples were analysed for gold, platinum and palladium using a 50 g PGM-ICP24 assay and for multi-elements using a 0.25 g ME-MS61 assay Sherlock Crossing rock chips samples were collected by grab sampling 1 – 3 kg of material. Sample sites were selected to be representative of the lithology sampled, and the same sampling technique was employed at each sample site where possible. Samples are pulverised in full and analysed for gold using a 50 g fire assay (Au-ICP22) and for multi-elements using a 0.25 g ME-MS61 assay Sherlock Crossing soil samples of ~200 g were collected from small pits 10 cm – 40 cm in depth and sieved to &LT80# mesh. A 25 g aliquot was digested via aqua regia (AuME-TL43)
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).	Balla Balla AC drilling was completed by Wallis Drilling, using a Mantis 200 drill rig with NQ sized drill rods
Drill sample recovery	Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. 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.	Sample recoveries were estimated from sample piles. Records were made of sample quality, including contamination and wetness. The rig utilises a cyclone to ensure all material is captured in metre intervals, with dust suppression to retain fines. The cyclone was regularly cleaned to minimise sample contamination No relationship between sample recovery or contamination and grade is recognised.
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. The total length and percentage of the relevant intersections logged.	AC chips were logged for qualitative and quantitative properties including interpreted lithology, alteration and mineralisation, magsus, and sample properties. Chips and pieces of core were photographed and stored for future test work. All one metre intervals are logged. Chips were not analysed for geotechnical or metallurgical properties, and this preliminary program will not be part of a Mineral Resource estimation Rock chip samples are geologically logged with quantitative and qualitative data collected including a description of lithology, vein type and vein densities, and alteration.
Sub-sampling techniques and sample preparation	If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality, and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled.	Balla Balla AC samples were speared from one metre sample piles into three metre composites. Spearing AC samples from piles on the ground is appropriate for the early exploration phase. Spearing is completed with a custom made pvc spear, held parallel to the ground to avoid contamination, and speared into the centre of the sample pile to best represent the entire metre drilled. Equal aliquots are combined into a three-metre composite for assay. Duplicate samples were collected for every 1 in 25 samples to check for repeatability. The sampling techniques and sample sizes are considered appropriate for the style of mineralisation. Rock samples are collected to best represent the material sampled across geological features.
Quality of assay data and laboratory tests	The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g., standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (if lack of bias) and precision have been established.	AC sampling and analysis is considered appropriate for early exploration and the style of mineralisation tested. QAQC includes 2 CRM standards, 2 blanks, and 4 field duplicates per 100 samples. The rock chip sample assay methodology is considered appropriate for the style of mineralisation tested. The method includes inserting 2 CRM standards and 2 blanks per 100 samples or at least one of each per sample submission. The soil sample assay methodology has low level detection for gold and multi-elements and is considered appropriate for soil geochemistry for outcropping or near surface mineralisation. The method includes insertion of at least 2 blanks 2 CRM standards and 4 field duplicates per 100 samples. No QAQC issues were detected for Au or ME performance, with CRM performance passing review and no bias detected.
Verification of sampling and assaying	The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data.	Primary data was collected in the field using Geobank for Field Teams 24.0, which was then forwarded to the database manager email for upload to the Geobank (v2025.0) database, buffered through a validation portal that ensures code and primary record compliance. Geobank is a front-end UX/UI tender software platform (developed and sold by Micromine) attached to a SQL v15.1 server. Assay data was loaded from lab certificates received from the registered laboratory by an internal database manager or external database consultant, and industry-standard audit trails and chain-of-custody was adhered to. Verification included checking the data against original logs and utilising laboratory certificates. No adjustments of the assay data were made.
Location of data points	Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control.	All surface sample locations were recorded by hand-held GPS using the GDA 2020 zone 50 coordinate system. AC holes are surveyed at the start of hole using a handheld compass and clino on the rig mast. There are no downhole surveys completed due to the shallow nature of drilling. Topographic control at Balla Balla is from SRTM data, which is of sufficient quality for the relatively flat project terrain
Data spacing and distribution	Data spacing for reporting of Exploration Results. 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.	AC holes are spaced at 50 m, on lines spaced between 640 m and 2.8 km. This spacing is not sufficient to derive any geological or grade continuity. Samples are composited to 3 m intervals. Limited rock samples taken are indicative of potential grade tenor. These do not represent or imply any continuity or scale potential. Soil samples were taken on a nominal grid of 40 m by 80 m orientated to be perpendicular to the interpreted strike of the system.
Orientation of data in relation to geological structure	Whether the orientation of sampling achieves unbiased sampling of possible structures and the 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.	AC drill lines were designed to be perpendicular to most structures and stratigraphy trends. AC holes were angled to the southeast, which is assuming a vertical or northwest dip to features. Drilling intersected lithological contacts and structures as anticipated, although it is at this stage unknown if other orientated structures are present. The soil sample grid was orientated to best intersect the lithological and structural trends at right angles. Rock samples were taken across features with geological data recorded to best reflect unbiased sampling of possible mineralised structures.
Sample security	The measures taken to ensure sample security.	All samples are stored and managed on site by internal staff. Samples are then transported by reputable companies to a registered laboratory where they are stored in a locked facility before being tracked and processed through the preparation and analysis system at the laboratory.
Audits or reviews	The results of any audits or reviews of sampling techniques and data.	No audits have been undertaken.

(Criteria listed in the preceding section also apply to this section)

Article content

Criteria	JORC Code explanation	Commentary
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 license to operate in the area.	The Balla Balla project is located on tenements E47/4703 and E47/4295. E47/4703 is held by SQM under the Harding Battery Metals JV, with Novo retaining a 25% interest in the tenement and 100% of the gold, silver, PGE, copper, lead and zinc mineral rights. E47/4295 is held by Meentheena Gold Pty Ltd, a wholly owned subsidiary of Novo. The drilling area falls within the Kariyarra Native Title claim. Novo have a tenement wide access agreement in place with Kariyarra and completed heritage surveys to allow AC drilling. Sherlock Crossing is located on tenement E47/3825, held by Karratha Gold Pty Ltd, a wholly owned subsidiary of Novo. It falls within the Ngarluma/Yindjibarndi Native Title Claim and is managed by the Ngarluma Aboriginal Corporation. Novo have an access agreement in place with Ngarluma and have completed a heritage survey to facilitate drilling. The tenements are currently in good standing and there are no known impediments.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	Balla Balla: Australia Inland Exploration and Esso Exploration conducted airborne and ground magnetics, an IP survey, diamond drilling, and thin section petrography targeting massive nickel and copper in the Sherlock Intrusion. The 1975 annual report concludes that any additional work on the tenement would only be justified if a new effective geophysical tool emerged Esso Exploration targeted the area in 1980 and 1981 with an additional aeromagnetic survey, an EM survey and RAB drilling. The RAB program consisted of 75 holes for a total of 1,535 m across the project area. All these targeted geophysical anomalies identified across the surveys conducted. Results were broadly disappointing with peak values of 101 ppm Ni, 196 ppm Cu, 127 ppm Zn, 0.5 ppm Ag, 115 ppm W, 92 ppm Pb and 0.05 ppm Au. Previous surface sampling was completed over the Ramquarry prospect in a JV between Gascoyne Gold, Dalrymple Resources and Sons of Gwalia in the 1997 to 1998 field season. 22 rock chip samples were taken, with results yielding no gold or base metal anomalies Golden State Mining in 2020 targeted VMS, shear hosted gold and to a lesser extent Ni-Cu sulphides. Results were broadly uninspiring with a peak Au value of 0.18 ppm Au Sherlock Crossing: Aarex 1997 (A53516 – A49869) collected thirty-five samples from outcrop or from the dump surrounding the main historical excavation at the Clarke Mine. The highest sample result was 84.8 g/t gold which averaged 68.5 g/t over four assays. Ascent Mining 2002 (A66185) collected twenty-one rock chip samples from Sherlock Crossing, located at the site of the historical Clarkes antimony mine, returning up to 98.8 g/t Au and 0.83% antimony Ourwest Corp 2007 (A76553) collected eleven rock chip samples which gave peak results of 3.78 g/t Au and 1390 ppm Sb. No other known work of relevance has been undertaken by other parties.
Geology	Deposit type, geological setting, and style of mineralisation.	The mineralisation style at Balla Balla is unknown. Historical work focussed largely on VMS or shear hosted mineralisation. Results in this release suggest hydrothermal alteration related to shear hosted mineralisation. Sherlock Crossing is an orogenic narrow and high-grade vein hosted system, within ultramafics.
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, including 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 plus 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.	Collar details of all aircore holes, significant intercepts for gold mineralisation, and all multi-element data is provided for selected elements in Appendices All rock sample and soil sample results are reported in Appendices, listing all significant multi-elements.
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.	Results from the AC program are low level. No weighted average or top cuts are applied. Significant intercepts are reported to a 10 ppb cut off, including 3 m of internal waste. Higher-grade results are reported to a 30 ppb cut off, and are higher-grade for the purpose of domaining zones of mineralisation only
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 (e.g., ‘down hole length, true width not known’).	True orientation of possible mineralisation is currently unknown. The AC drilling was orientated to be perpendicular as best as practical to potential structures. Only down hole lengths of mineralisation are reported here. Rock sample results are indicative in nature and, whilst representatively sampling the target lithology, do not contain any width or length information other than a qualitative description of the target.
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.	Refer to the body of the release for appropriate maps and diagrams.
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.	Due to the large number of downhole gold assay results, not all results are reported in Appendix 2. All significant results greater than 10 ppb are listed, including any higher-grade where intersected. The full multi element suite comprises 50 elements. Not all elements are reported in Appendix 3, but a selection relevant to the mineralisation style is reported. For these elements, all end of hole and down hole intervals are listed. All rock sample and soil sample results are 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.	No additional data.
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.	Refer to the body of the release. Further hyperspectral work and geochemical analysis will be conducted on selected material for Balla Balla, to determine whether alteration can vector towards a mineralisation system. Novo intends to complete a ~ 1,000 m maiden RC drilling program at the Sherlock Crossing Au-Sb project in H2 2025.
