SARAMA RESOURCES GEOCHEMISTRY PROGRAM UNDERWAY AT COSMO GOLD PROJECT
First Major Exploration Program in Several Decades on Highly Prospective Cosmo Project with Soil Sampling Designed to Generate Drill Targets
PERTH, AUSTRALIA / VANCOUVER, CANADA. Sarama Resources Ltd. (“ Sarama ” or the “ Company ”) (ASX:SRR, TSXV:SWA) is pleased to advise that it has commenced a multi-stage regional soil-geochemistry program at its majorityowned[(1)] 580km² Cosmo Gold Project (the “ Project ”)[(2)] in the Eastern Goldfields of Western Australia. The program is the most significant exploration work to be undertaken on the Project in decades and is a foundational stage for drill target generation.
The program follows the Company’s acquisition of a majority and controlling interest in the Project in December 2024 and its agreement to acquire a majority and controlling interest in the nearby Mt Venn Project in January 2025[(3)] . In aggregate, the belt-scale projects will cover approximately 1,000km²[(][2,3)] and +100km of strike-length of greenstone rocks and are well-positioned and underexplored, presenting an exciting opportunity for Sarama in the Laverton Gold District which is known for its prolific gold endowment (refer Figure 1).

Sarama’s President, Executive Chairman, Andrew Dinning commented:
“We are very pleased to get exploration underway and bring the belt-scale Cosmo Project to account. Cosmo is genuinely underexplored, has all the geological ingredients to generate a discovery and with core team members that led the discovery of the multi-million ounce Moto and Sanutura[(6) ] Projects in Africa and we look forward to seeing what this project can deliver. Leveraging its position at the Cosmo Project, upon completion of the transaction to acquire a majority interest in the nearby Mt Venn Project, Sarama will have 1,000km[2] of highly prospective ground in the prolific Laverton Gold District.”
Cosmo Project
The Project is comprised of 7 contiguous exploration tenements covering approximately 580km² in the Eastern Goldfields of Western Australia, approximately 85km north-east of Laverton and 95km west of the regionally significant Gruyere Gold Mine[(4)] . The Project is readily accessible via the Great Central Road which services the Cosmo Newbery Community.
The Project captures one of the last unexplored greenstone belts in Western Australia and with a strike length of +50km , the Cosmo Newbery Belt represents a large and prospective system with gold first being discovered in the area in the 1890’s. Multiple historical gold workings are documented within the Project area and work undertaken to date has identified multiple exploration targets for follow up.
Despite this significant prospectivity, the Project has seen virtually no modern exploration or drilling of merit due to a lack of land access persisting over a significant period. As a result, the Project has not benefited from the evolution of soil geochemical and geophysical techniques which now facilitate effective exploration in deeply weathered and complex regolith settings which is particularly pertinent given approximately 75% of the Project area is under cover.
Following the relatively recent securing of land access, the Project is now available for systematic and modern-day exploration programs to be conducted on a broad scale. Future exploration programs will initially follow-up preliminary targets generated from regional soil sampling and limited historic reconnaissance drilling programs, a majority of which extended to approximately 5m below surface with a small percentage extending up to 30m below surface.

Cosmo Project - Regional Soil Geochemistry Program
The soil geochemistry program at the Cosmo Project is the first large-scale systematic exploration program to be conducted on the Project in several decades . Similar fieldwork to date has included discrete, small-scale soil geochemistry programs designed to evaluate localised areas of interest and select broad-spaced reconnaissance lines. Much of the work was conducted in the period 1970-1995 and is considered to be of limited value given the nature of sample collection, the regolith environment, analytical methods utilised at the time and quality control measures applied.
2
Sarama’s exploration strategy is to conduct broad-scale exploration programs to generate multi-layer datasets, developing a foundational understanding of the potential for gold mineralisation at the Project. Given the lack of base-level work conducted on the Project to date, there is an immediate need to gather regional gold-in-soil geochemistry data to complement preliminary magnetic and radiometric airborne geophysical surveys . This geochemistry work, combined with field mapping, is designed to identify areas of near-surface gold anomalism.
The majority of the 580km² Project will be covered with gridded soil sampling of spacing in the order of 400-800m x 100m on an east-west grid. Higher-priority areas will initially be covered by a 200m x 100m grid. Sarama intends to use the UltraFine+[TM] analytical process, developed and commercialised by the CSIRO (Commonwealth Scientific and Industrial Research Organization) specifically to assist in the exploration of the complex regolith conditions which are prevalent in the Eastern Goldfields of Western Australia (refer Figure 2). The method was not commercially available for the majority of the Project’s exploration history and Sarama is keen to capitalise on this technical advancement in soil geochemistry which has been used by prominent mineral exploration companies including WA1 Resources, OreCorp, Sayona Mining and S2 Resources.

Figure 2 –Highly Prospective Western Greenstone Belt Suited to Soil Sampling for Drill Targeting
Interpretations of previous airborne geophysical surveys have identified numerous areas of interest associated with structural features, lithological contact zones – which are considered to create or are associated with favourable host settings for gold mineralisation .
The regionally significant Sefton Structural Corridor , extending for +50km along the western edge of the Project hosts a series of priority areas. Further target areas in close association with two prominent internal granitic intrusions within the greenstone belt illustrate further potential for gold mineralisation. Transported soil cover over the highly prospective western portion of the greenstone belt ideally suited to soil geochemical sampling for drill targeting.
Sarama intends to prioritise these high-potential areas within the larger program to generate potential drill targets for testing as soon as possible. In addition to these zones, historical prospecting activities by various operators within the Project have returned high-grade gold values of up to 52g/t Au[(5)] in surface grab samples. Further ground-truthing

work will be undertaken in these areas with a view to incorporating them into the priority areas. Figure 3 shows the initial areas prioritised for the program.
Experienced field crews have already been mobilised to the Project and are executing the work program with good productivity and quality control. The first batch of samples is expected to be submitted for analysis in the next 2 weeks.

| 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. Preface The Cosmo Project (the “Project”) is comprised of several exploration tenements over which exploration has occurred to varying degrees. Prior to Sarama Resources (“Sarama”) becoming involved in the Project in Q4 2024, the majority of reliable exploration work has been conducted in years, recent to 2024, by Cosmo Gold Pty Ltd (“Cosmo Gold”). Other historical work was undertaken by various operators in various discrete campaigns that were typically of narrow focus. Grab Sampling (Other Operators)– various operators conducted sampling on an ad-hoc basis in areas of geological interest and for material of geological or mineralogical interest during the period circa 1969-2002. An opinion on the quality of this historical sampling is not able to be formed given the general lack of information available. Lag Sampling (Other Operators)– a previous operator conducted sampling over grided areas in 2000-2003. An opinion on the quality of this historical sampling is not able to be formed given the general lack of information available, however it is noted that many of the samples collected were in areas of transported cover and may not have been true lag material. MagLag Sampling (Other Operators)– various operators conducted sampling over various gridded areas in 2001-2002. No information is available to outline sampling methodology. An opinion on the quality of this historical sampling is not able to be formed given the general lack of information available. Stream Sediment Sampling (Other Operators)– a previous operator conducted stream sediment sampling in 2000-2003. An opinion on the quality of this historical sampling is not able to be formed given the general lack of information available. Soil Geochemistry Sampling (Other Operators)– various operators conducted sampling over gridded areas in 1994 and 2000-2003. Levelling issues are apparent in the 1994 sampling so quantity of sample is questionable. The 2000-2003 sampling focussed on the -2mm fraction and is considered of acceptable quality in outcropping areas and less so for transported or covered areas. Soil Geochemistry Sampling (3D Resources / Cosmo Gold)– sampling was conducted on gridded areas of outcrop in 2017. Sampling targets the 1mm fraction for Mobile Metal Ion analysis and -250 micron fraction for multi-element acid digest analysis. Soil Geochemistry (Cosmo Gold & Sarama)– sampling conducted on gridded areas from hand-dug holes to approximately 100-200mm depth. The full sample is sieved to -0.9mm (or -2mm) in the field to produce a sub-sample of approximately 200g for further sub-sampling at the laboratory. The +0.9mm (or +2mm) fraction is discarded in the field. Standard field equipment is used to collect and produce the initial sub-sample. The sampling procedure aims to ultimately target the dispersion/plume of leached minerals in a -2 micron fraction (for analysis by Labwest’s UltraFine+TMprocess) for target vectoring and the depth and type of sample preparation is considered to produce a robust quality sample across various regolith types. Rotary-Air-Blast (“RAB”) Drilling (Other Operators)– limited information exists on the sampling techniques used for the H1 1995 RAB drilling program. It is noted that sampling occurred in 1m intervals prior to compositing over a 4m interval for analysis. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. It is assumed that historical sampling was located using digital survey equipment to capture and project point sample locations, however upon review, it is noted that locations of some sampling does not correlate with expectations or observations and there may either be equipment inaccuracy or datum ambiguity. Work undertaken by Cosmo Gold and Sarama is has used digital survey equipment that is appropriately calibrated/checked and which has an appropriate level of accuracy. |

| The various non-drilling sampling programs conducted on the Project targeted certain mediums according to the nature and intent of the specific sampling program. In general, grab sampling is expected to be representative of targeted material. Lag, maglag, stream and soil sampling all target different mediums and reviews of historical information have indicated that some surveys are unreliable, possibly to the sampled mediums not being representative of the targeted medium (or even being of the targeted medium. Soil Geochemistry Sampling (3D Resources / Cosmo Gold) – sampling by the UFF method in sand covered areas targets a specific fraction of the cover material and seeks to measure a response from leached material. Adequate QAQC controls for sampling have been put in place to ensure representativity. Soil Geochemistry Sampling (Cosmo Gold & Sarama) – sampling by the ultra-fine fraction (“UFF”) method in sand covered areas targets a specific fraction of the cover material and seeks to measure a response from leached material. Fundamentally, the design of the technique broadens its application across a range of material types within the regolith and as a result sensitivity of results to sample representativity is reasonably low. The sampling is conducted with the assistance of regolith mapping to aid data processing and levelling of results over different regolith types. RAB Drilling (Other Operators)– limited information exists on the drilling techniques used for the H1 1995 RAB drilling program and no comment can be made on procedures to ensure sample representativity and calibration of measurement tools. Collar location checking work in recent times has shown the co-ordinates of the drill program to suffer from varying degrees of inaccuracy. It is noted that drilling was open hole so sample contamination from wall material is likely to have occurred. |
|
| Aspects of the determination of mineralization that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘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 mineralization types (eg submarine nodules) may warrant disclosure of detailed information. The presence of gold and other elements of economic interest have been identified by the use of ad-hoc and structured exploration programs which feature soil geochemistry and grab sampling in the early stages, before drilling in more advanced exploration. Details on sampling, sub-sample preparation, analytical techniques and reporting of significant results are contained in the following sections. Thes e methods are either widely used in the industry or are commercially available. |
|
| Drilling Techniques |
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). RAB Drilling (Other Operators)– limited information exists on the drilling techniques used for the H1 1995 RAB drilling program. It is noted that drilling was open hole. |
9
| Drill Sample Recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. RAB Drilling (Other Operators)– no information is available on sample recovery specifics by drilling. |
| Measures taken to maximize sample recovery and ensure representative nature of the samples. RAB Drilling (Other Operators)– no information is available on procedures and techniques to ensure sample recovery and representativity of sampling. |
|
| 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. RAB Drilling (Other Operators)– no information is available on sample recovery and therefore any potential for sample bias is unable to be determined. |
|
| 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. RAB Drilling (Other Operators)– drilling information for the H1 1995 drill program was recorded on log sheets, however this information has been lost and has not been reviewed. It is assumed that logging was conducted on 1m intervals. This drilling was reconnaissance in nature and would not be suitable for the purposes of Mineral Resource estimation or other technical work. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc) photography. RAB Drilling (Other Operators)– drilling information for the H1 1995 drill program was recorded on log sheets, however this information has been lost and has not been reviewed. |
|
| The total length and percentage of the relevant intersections logged. RAB Drilling (Other Operators)– approximately 3,001m was drilled in the H1 1995 drill program and it is assumed that all drilling was logged, however this information has been lost and has not been reviewed. |

If core, whether cut or sawn and whether quarter, half or all core taken. No core drilling has been undertaken. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. Grab Samples (Other Operators)– no sub-sampling occurs in the field, however lab-based sub-sampling following crushing and pulverisation will normally take place before analysis. Details of such sub-sampling are unknown. Grab Samples (Cosmo & Sarama) -no sub-sampling occurs in the field, however lab-based sub-sampling follows crushing and pulverisation with a scoop of dry pulverised material taken as the charge for analytical material. Soil Geochemistry (Other Operators) -no information is available on sub-sampling procedures or sample preparation, however it is expected that field- based and lab-based subsampling would have been conducted. Lag, MagLag and Stream Sediment Sampling (Other Operators) -no information is available on sub-sampling procedures or sample preparation, however it is expected that field-based and lab-based subsampling would have been conducted. Soil Geochemistry (Cosmo Gold & Sarama)– from the initial -0.9mm (or -2mm) sub-sample material, further lab-based sub-sampling is undertaken to produce a -2 micron fraction for analysis using the LabWest UltraFine+TMprocess. The as-received -0.9mm (or -2mm) sub-sample is again sub-sampled using a scoop to produce an intermediate 40g sub-sample. This intermediate sub-sample is subjected to dispersion and settling process in an aqueous solution. A sub-sample of the solution,targetingthe -2 micron fraction,is taken and subjected to dewateringbycentrifuge. The resultingcake material |
10
| is dried and subsequently crushed before a final 0.2g sub-sample is taken by scoop for analysis. No homogenisation steps are undertaken during the process, partly due to the nature of the targeted UFF and the techniques used for its production. RAB Drilling (Other Operators)– no information is available on sub-sampling procedures or sample preparation. |

| For all sample types, the nature, quality and appropriateness of the sample preparation technique. Grab Samples (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the nature, quality and appropriateness therein. Grab Samples (Cosmo & Sarama) –no sub-sampling occurs in the field, however lab-based sub-sampling follows crushing and pulverisation with a scoop of pulverised material taken as the charge for mineral analysis. Sub-sample quantities vary according to analytical method, however is generally 30g or 50g. This technique is considered to be appropriate for the objective of the sampling exercise. Lag, MagLag and Stream Sediment Sampling (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the nature, quality and appropriateness therein. Soil Geochemistry (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the nature, quality and appropriateness therein. Soil Geochemistry (Cosmo Gold & Sarama)– the methodologies for initial preparation of sub-samples are discussed above. The LabWest UltraFine+TM process targets an ultrafine fraction of the head sample and the nature of the geochemistry programs, host geological terrane and regolith conditions encountered result in the sampling and sub-sampling method as being robust and appropriate. RAB Drilling (Other Operators)– no information is available on sub-sampling procedures or sample preparation so no comment can be made on quality or appropriateness. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Grab Samples (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the representivity of such samples. Grab Samples (Cosmo & Sarama)– crushing and pulverisation of the primary occurs in analytical laboratory using purpose-specific equipment maintained and cleaned after each sample according to defined procedures. Sub-sampling of the primary sample for analytical charge is conducted after pulverisation to target representativity. Lag, MagLag and Stream Sediment Sampling (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the representivity of such samples. Soil Geochemistry (Other Operators)- no information is available on sub-sampling procedures so no comment can be made on the representivity of such samples. Soil Geochemistry (Cosmo Gold & Sarama)– collection of primary samples in the field is undertaken using guidelines and procedures developed specifically for the Project and which include targeted sample depth, sample handling requirements and equipment cleaning requirements. Comprehensive field logs are compiled for each sample which can be used to identify sample and sub-sampling issues. Sample collection procedures incorporate the insertion of blanks, duplicates and certified reference materials (“CRM”) into the sample stream delivered to the laboratory at rates of approximately 2%, 2% and 3% respectively to monitor sample repeatability (in the case of duplicates) and laboratory performance (in the case of blanks and CRM). Laboratory-based sub-sampling is undertaken according to set procedures and using specialist equipment and techniques appropriate to the task and in a controlled environment. To monitor sub-sampling quality and laboratory performance, blanks, duplicates and CRM are each inserted at a rate of 2 in 44 samples. Duplicates are inserted at the point of taking a 40g sub-sample from as-received material and blanks and CRM are inserted into the sample stream prior to the analysis stage (that is, after the production of the 0.2g sub-sample). The results of the internal laboratory quality control are reported regularly on a batch-by-batch basis, and the results were closely monitored by Sarama personnel. Ad-hoc QAQC activities, including check assaying and re-sampling, were conducted by both Cosmo and Sarama. RAB Drilling (Other Operators)– limited information is available on sub-sampling procedures or sample preparation so no comment can be made on quality or appropriateness. References to ‘control duplicates’ have been noted in historical reports for the drilling however sufficient detail is not available to support assessment of the procedures. |
11
| 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. Grab Samples (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the representivity of such samples. Grab Samples (Cosmo & Sarama)– given the low volumes and nature/objectives of this sampling, only reference materials and duplicate samples are only inserted into the sample stream on an ad-hoc basis. Despite this, the protocol still provides insights/checks on analytical and sample preparation performance. Lag, MagLag and Stream Sediment Sampling (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the representivity of such samples. Soil Geochemistry (Other Operators)- no information is available on sub-sampling procedures so no comment can be made on the representivity of such samples. Soil Geochemistry (Cosmo Gold & Sarama)– details of controls instituted are included in preceding sections. RAB Drilling(Other Operators)– limited information is available on sub-sampling procedures or sample preparation so no comment can be made on quality or appropriateness. RAB drilling was open hole so some contamination is likely to have occurred from unconsolidated wall material. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. Grab Samples (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the appropriateness of such samples. Grab Samples (Cosmo & Sarama)– sub-sampling is conducted post pulverisation (generally <100 micron) and minerals of interest are extracted to have grain sizes lower than this. The nature/objective of the primary sampling program is intended to provide reconnaissance-level results only for future follow up so any issues regarding representativity are deemed to not be of significance. Lag, MagLag and Stream Sediment Sampling (Other Operators)– no information is available on sub-sampling procedures so no comment can be made on the appropriateness of such samples. Soil Geochemistry (Other Operators)- no information is available on sub-sampling procedures so no comment can be made on the appropriateness of such samples. Soil Geochemistry (Cosmo Gold & Sarama)– the geochemistry programs target broad and subtle metal signatures within the sub-surface horizon. The primary sampling and subsequent sub-sampling procedures are designed to produce an UFF for further analysis at very low detection limits. The combination of program objective, sampling procedures and analytical process and capability are such that the sample sizes are deemed appropriate. RAB Drilling (Other Operators)– limited information is available on sub-sampling procedures or sample preparation so no comment can be made on quality or appropriateness. |

| 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. Grab Samples (Other Operators)– no information is available on analytical techniques or procedures. Grab Samples (Cosmo & Sarama)– for Au-only assays, samples assayed using fire assay techniques with 30g or 50g charge and AAS finish, providing total Au content. Multi-element assays are determined using acid/solvent digest prior to a range of finishing options including ICP-AES, XRF, AAS or MS with these techniques giving generally near-total element contents (according to specific techniques used). The nature/objective of the sampling program is such that near-total analysis as part of a suite of elements is acceptable. Lag, MagLag and Stream Sediment Sampling (Other Operators)– no information is available on analytical techniques or procedures. Soil Geochemistry (Other Operators)– historical programs have used a variety of analytical methods on samples, which are assumed to be unmodified. Analytical techniques included ICP (multi-element) and fire assay (Au only) based on either Aqua Regia (partial) or NaCN-based BLEG leach preparation techniques (total). Limited information is available on the laboratory techniques for all historical programs. The analysis of unmodified samples in the specific regolith conditions of the Project, particularly in the sand-covered areas, results in head samples of very low metal content which has sometimes been below the lower detection limits of the analytical methods employed. The variation in regolith conditions and the suitability of analytical techniques has generally produced an ‘erratic’ historical dataset which is only suitable for broad planning purposes for replacement programs. Soil Geochemistry (Cosmo Gold & Sarama)– as part of LabWest’s Ultrafine+TMprocess, the final -2 micron sub-samples are subjected to a microwave- enhanced Aqua Regia digest at elevated temperature andpressureprior to multi-element analysis byICP-MS and ICP-OES techniques toprovide a suite |
12
| of ~65 elemental concentrations. The nature of the full sub-sampling process is that the analysis is taken on a modified sample (only the -2 micron fraction). The Aqua Regia digest method provides varying degrees of digestion for different minerals and is considered to be a ‘partial’ method. The analytical technique is considered to be appropriate given the purpose of the geochemistry program and the Project’s regolith conditions. RAB Drilling (Other Operators)– limited information is available on analytical procedures. Records indicate Au content was determined using the GG313 method code at Analabs (50g charge fire assay with AAS finish). Samples were also analyses for As content, however the method is unknown. Fire assays provide total Au content. No information is available on QAQC so no comment can be made on the quality of assays. |
|
| 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. No geophysical tools have been used for analysis of soil geochemistry or drilling samples. |
|
| Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. Grab Samples (Other Operators)– no information is available on the QAQC controls implemented (if any). Grab Samples (Cosmo & Sarama)– given the nature/objective of the sampling program, reference materials and lab-based duplicates are only inserted int the sample stream on an ad-hoc basis. All results, before being accepted into the database, have been checked for analytical performance and sub- sampling repeatability. Lag, MagLag and Stream Sediment Sampling (Other Operators)– no information is available on analytical techniques or procedures. Soil Geochemistry (Other Operators)– no information is available on the QAQC controls implemented (if any). Soil Geochemistry (Cosmo Gold & Sarama)– details of the QAQC procedures for sampling and analysis using the LabWest UltraFine+TMmethod are listed above. All results, before being accepted into the database, have been checked for analytical performance and sub-sampling repeatability. RAB Drilling (Other Operators)– limited information is available quality control procedures instituted for the analysis of drilling samples. References to ‘control duplicates’ have been noted in historical reports for the drilling however sufficient detail is not available to support assessment of the procedures. No analytical checks with external laboratories have been noted. |
|
| Verification of Sampling and Assaying |
The verification of significant intersections by either independent or alternative company personnel. RAB Drilling (Other Operators)– no definitive verification work has been undertaken. Some collars have been located in the field by company personnel, but historical sample are not available for check sampling or other verification processes. |
| The use of twinned holes. RAB Drilling (Other Operators)– limited information is available on verification of drilling and it is unlikely that any twinned holes were drilled given the nature of the program. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Grab Samples (Other Operators)– historical records are limited and no information is available on primary data capture, data entry, data verification or data storage. Information used for future program planning purposes compiled from partial records in reports and incomplete ad-hoc data records. Grab Samples (Cosmo & Sarama) –primary sample collection data is recorded by hand on purpose-specific log sheets in the field. Data sheets are entered into spreadsheets. Assay records are sent by the laboratory in digital format and matched to sample data to form a master database in electronic format. Lag, MagLag and Stream Sediment Sampling (Other Operators)– historical records are limited and no information is available on primary data capture, data entry, data verification or data storage. Information used for future program planning purposes compiled from partial records in reports and incomplete ad-hoc data records.

| Soil Geochemistry (Cosmo Gold & Sarama) – primary sample collection data is recorded by hand on purpose-specific log sheets in the field. Data sheets are entered into spreadsheets nightly and transmitted to the database manager for collation. Assay records are sent by the laboratory in digital format and matched to sample data to form a master database in electronic format. RAB Drilling (Other Operators)– limited information is available and no comment can be made on information flow or data collection and storage procedures. |
|
| Discuss any adjustment to assay data. Grab Samples (Other Operators)– historical records are limited and no assessment of adjustments (if any) can be made. Grab Samples (Cosmo & Sarama)– once the data is compiled into the master database, no routine edits are made. Notations for lack of sample or other exceptions are made manually if required. Lag, MagLag and Stream Sediment Sampling (Other Operators)– historical records are limited and no assessment of adjustments (if any) can be made. Soil Geochemistry (Other Operators)– historical records are limited and no assessment of adjustments (if any) can be made. Soil Geochemistry (Cosmo Gold & Sarama)– once the data is compiled into the master database, no routine edits are made. Notations for lack of sample or other exceptions are made manually if required. RAB Drilling (Other Operators)– limited information is available on drilling data and no results are being reported externally. No adjustments have been made to base level analytical data and or aggregated values. Working adjustments have been made to collar locations in an attempt to correlate with on-ground observations. Ultimately the data is deemed to be of low reliability so is used for internal guidance purposes only. |
|
| 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. No Mineral Resources are being reported. |
| Specification of the grid system used. All data is referenced in the GDA2020 MGA Zone 51 coordinate system in reporting. Historical data has been collected using a variety of grid systems and it is noted that some data is of low positional reliability. |
|
| Quality and adequacy of topographic control. No specific topographical control points are used. Surveying conducted using GPS, differential GPS or real-time kinematic GPS equipment which gives acceptable accuracy for the stage of the Project and which doesn’t require fixed control points. |
|
| Data Spacing and Distribution |
Data spacing for reporting of Exploration Results. Grab Samples (Other Operators)– samples were taken at random locations at no specific spacing. Grab Samples (Cosmo & Sarama) –samples were taken at random locations at no specific spacing. Lag, MagLag and Stream Sediment Sampling (Other Operators)– MagLag samples were taken in various grid locations and orientations. Spacing varied 70-100m x 70-100m and lines oriented at N090° and N045°. Soil Geochemistry (Other Operators)– historical records are limited and no assessment of adjustments (if any) can be made. Soil Geochemistry (Cosmo Gold & Sarama)– samples are collected over a grid-oriented east-west with design sample point spacing varying according to specific program objectives. The general trend of the prospective lithology and structure within the Project is approximately NNW so east-west is considered to be acceptable. The following general grid spacings have been used: 800m x 100m (NS x EW) grids oriented N090° have been used for initial regional surveys over large areas; 400m x 100m (NS x EW) grids oriented N090° have been used for follow-up or more focussed surveys; 200m x 100m (NS x EW) grids oriented N090° have been used for infill surveys in higher-priority areas; and Closer spaced grids may be adopted for special target areas requiring more granularity. Hole spacing (within each fence) ranges 20-50m but is typically 20m. |
14
| RAB Drilling (Other Operators)– commentary in drilling summary reports for the H1 1995 drilling indicates that hole collars were 10-20m apart on each drill line. Drilling was reconnaissance in nature and lines were positioned relative to gold-in-soil anomalism and old workings and were typically single lines of varying length. No Exploration Results are being reported for this drilling. |
|
| 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. All Surface Sampling (All Operators)– the sampling is conducted at an early stage of exploration and data is not appropriate for use in Mineral Resource estimates. RAB Drilling (Other Operators)– the drilling is early-stage reconnaissance in nature and the type of drilling is not suitable for incorporation in Mineral Resource estimates. |
|
| Whether sample compositing has been applied. All Surface Sampling (All Operators) – the sampling is on the basis of 1 sample per collection point and no compositing occurs. RAB Drilling (Other Operators)– the H1 1995 drilling program was sampled on 1m intervals and composited on 4m intervals prior to analysis. |
|
| 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. Non-Soil Geochemistry Surface Sampling (All Operators)– the sampling is conducted at variable point spacings and generally at specific features of interest, is highly selective and to a large extent is agnostic to the orientation of structures or features. This is acceptable given the nature and objective of these types of programs. Soil Geochemistry (Other Operators)– sample grids have been generally oriented east-west with one exception (1994 Viscovich) of line orientation N070°. The general trend of the prospective lithology and structure within the Project is approximately NNW so all grids are considered to be acceptable. Soil Geochemistry (Cosmo Gold & Sarama)– sample grids are oriented east-west with design sample point spacing varying according to specific program objectives. The general trend of the prospective lithology and structure within the Project is approximately NNW so an east-west is considered to be acceptable. The orientation will be sub-optimal for features or lithological units with orientation oblique to the NNW trend and samples taken from the broader-spaced grid lines may fail to generate a response. RAB Drilling (Other Operators)– the H1 1995 drilling program undertaken with lines oriented 090°N. This is approximately perpendicular to the strike of major regional structures, however mineralisation may occur at a smaller scale in different orientations. No comment can be made on whether the sampling was biased. |
| 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. RAB Drilling (Other Operators)– indeterminate. |

| Reviews | sampling techniques and data. | Soil Geochemistry (Cosmo Gold & Sarama)– the limited amount of exploration work undertaken on the Project has resulted in limited review and audit | |
| work being undertaken. An orientation program/review was conducted by Sugden Geoscience in 2022 to determine appropriate sample collection and | |||
| analytical techniques for future geochemistry programs. This review made recommendations on preferred techniques which have since been adopted | |||
| as the primary approach for soil geochemistry. The review examined QAQC performance for sample collection and analysis. The review concluded that | |||
| sub-sampling to produce an ultra-fine fraction for analysis was a suitable method for the sand-covered terrane that is prevalent for most of the Project | |||
| area. | |||
| General– as part of Cosmo Gold Limited’s application to list on the Australian Securities Exchange in 2021, an Independent Technical Assessment Report | |||
| was compiled by CSA Global in late 2020. This report reviews historical exploration by phase/operator and makes broad assessment on the quality and | |||
| reliability of certain surface sampling programs. In general, the report concludes that most historical work (pre-Cosmo Gold era) is unreliable, suffering | |||
| from sample location uncertainty, unsuitability of sample medium and lack of QAQC controls to monitor sample preparation and analytical performance. | |||
| The report recommends expansion of ultra-fine fraction based sampling programs to cover the substantially unexplored areas undercover. |

| 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 Cosmo Gold Project (the “Project”) is comprised of 7 exploration tenements for which Exploration Licences have been issued by the Government of Western Australia: • E38/2274 – 42 blocks (approx. 117km²), initially granted 10/06/2011, current term expires 09/06/2025 (ongoing 2-year terms). • E38/2627 – 17 blocks (approx. 51km²), initially granted 11/05/2012, current term expires 10/05/2026 (ongoing 2-year terms). • E38/2774 – 17 blocks (approx. 51km²), initially granted 29/07/2013, current term expires 28/07/2025 (ongoing 2-year terms). • E38/2851 – 37 blocks (approx. 112km²), initially granted 12/03/2014, current term expires 11/03/2026 (ongoing 2-year terms). • E38/3249 – 9 blocks (approx. 27km²), initially granted 18/07/2018, current term expires 17/07/2028 (2nd5-year term). • E38/3456 – 35 blocks (approx. 106km²), initially granted 29/04/2021, current term expires 28/04/2026 (1st5-year term). • E38/3525 – 39 blocks (approx. 118km²), initially granted 01/07/2021, current term expires 30/06/2026 (1st5-year term). An Exploration Licence has an initial term of 5 years and, subject to the holder of the Exploration Licence satisfying certain reporting and expenditure requirements, it can be extended for a further 5 years and then periods of 2 years thereafter. A minimum of 40% of the surface area covered by the Exploration Licence must be surrendered at the end of the 1styear of the second 5-year term. All tenements are located within the Mt Margaret Mineral Field (District 38) and are approximately 80km north-east of Laverton, WA. Pursuant to the Mining Regulations 1981 (WA), the State Government of Western Australia is entitled to an_ad valorem_royalty (less any allowable deductions) for metal and minerals produced from the Project. Applicable rates are 7.5% (bulk minerals), 5% (concentrates), 2.5% (metals). On 13 August 2024, Sarama entered into an agreement with Cosmo Gold and Adelong Gold Limited (“Adelong”) which provides for Sarama to acquire an initial 80% of Cosmo’s interest in the Project, with an option for Sarama to acquire the remainder of Cosmo’s interests in the Project within a 2-year period for an exercise price of A$1.25M, payable in either cash or shares in Sarama, at Sarama’s election. Prior to the exercise of this option and/or until a ‘decision to mine’ is made in respect of the Project, Sarama shall operate and manage the Project under an unincorporated joint venture with Sarama being responsible for all costs. Following a ‘decision to mine’ and if Sarama did not elect to acquire the remainder of Cosmo’s interest within the 2-year option period, Cosmo must contribute its pro-rata share of project costs or dilute its interest. In the event a party’s interest falls below 10%, that party’s interest automatically converts to a 0.5% net smelter return on production from the Project. As part of the agreement, certain debt payable by Cosmo to Adelong will be discharged through the issuance of consideration shares and warrants in Sarama to Adelong. Cosmo, prior to completion of the transaction involving Sarama, currently has a 100% interest in all the tenements comprising the Project, with the exception of E38/2274, in which it has a 75% interest. The majority of the Project is located within Aboriginal Reserve #22032 which is an area proclaimed to be an Aboriginal Reserve under Part 3 of the Aboriginal Affairs Planning Authority Act (“AAPAA”) 1972. The land is administered by the Aboriginal Lands Trust for the benefit and use of Aboriginal communities and a Mining Entry Permit to access for the purposes of conducting mineral exploration was granted by ministerial authority to Cosmo Gold in May 2021. The entry permit has no specific expiry and a process for its transfer/novation to Sarama has been commenced. All Exploration Licences comprising the Project are located within the reserve with the exception of E38/2627 (71.2% excluded), E38/3456 (95.5% excluded). The Project is subject to two registered Native Title claims, each covering mutually exclusive areas. In September 2019, the Yilka and Yilka #2 and Sullivan Family claimants (representing as a unified body corporate, Yilka Talintji Aboriginal Corporation), were determined to hold Native Title over the following Exploration Licences: E38/2627 (28.8%), E38/2774 (100%), E38/2851 (100%), E38/3249 (100%), E38/3456 (4.5%), E38/3235 (100%) and E38/2274 (100%). In August 2018, a claim for Native Title lodged by the Waturta Native Title Claim Group was registered, affecting the following Exploration Licences: E38/2627 (71.2%) and E38/3456 (95.5%). Cosmo Gold has established land access agreements with these two Native Title groups to undertake mineral exploration whilst ensuring the preservation of Aboriginal sites of significance. These agreements include processes for land clearance by heritage surveys and feature annual land access payments which generally compensate for disturbance by exploration and related works and include schedule of rates for ad-hoc land clearance. The Project is not affected by any wilderness, national parks or other environmental designations. |

| Exploration | Acknowledgment and appraisal of | Historical exploration undertaken at the Project is summarised below: | |
| Done by Other Parties |
exploration by other parties. | • United Nickel 1970-1974– Ni focussed exploration in central project area consisting mainly of surface prospecting and mapping. • United Nickel 1969-1978- Ni focussed exploration in central project area consisting mainly of surface prospecting and mapping. Grab sampling returned anomalous base metals values. |
|
| • Max Viscovich 1994– Au focussed exploration in central project area delineated a number of +20ppb Au anomalies in gridded geochemistry, | |||
| however positional accuracy is questionable and data is considered of low reliability. | |||
| • Ilara/Gondwana Resources (Magnet Group) 1994– Au, Ag and Cu focussed exploration in central project area delineated a number of +20ppb Au | |||
| anomalies (coincident with Ag anomalism) in gridded geochemistry, however positional accuracy is questionable and data is considered to be only | |||
| of moderate use for further geochemistry survey planning. The operator conducted a RAB drilling program (223 holes for 3,001m) based on gold- | |||
| in-soil anomalism however this drilling has been assessed to be poorly designed to test potential targets and appears to suffer from positional | |||
| inaccuracy. | |||
| • Asarco/Yamarna Goldfields 1997-2001– desktop geology and regolith interpretation using remote sensing data on a small part of the current | |||
| Project’s area. | |||
| • Fargo Investments/Intercontinental Gold Investments 1993-2000– desktop work with aerial photo and remote sensing data to produce | |||
| interpretations of geology and regolith and comprehensive geological reviews. | |||
| • Ilara/Gondwana Resources 2000-2002– review and reconnaissance fieldwork focussing on Au, Ni, Cu and Co. A small Au only grab sampling | |||
| program confined to quartz vein areas in central Project returned variable Au values, ranging 0-49g/t Au. MagLag sampling conducted over the | |||
| Viscovich (1994) area identified a number of +20ppb and +30ppb Au anomalies partly coinciding with old workings. Accuracy of sampling grid | |||
| location is uncertain. | |||
| • Fargo Investments/ Intercontinental Gold and Mining 2000-2003– the group advanced previous desktop studies to fieldwork and acquired | |||
| remote sensing and airborne magnetic data (200m line spacing). Fieldwork included reconnaissance mapping, soil geochemistry orientation, and | |||
| sampling of stream sediments, grab material, surface lag and sub-surface soils. Stream sediment sampling returned low values, however one | |||
| 17ppb Au value corresponds with a 176ppb Au soil anomaly. Rock samples returned low values and were located east of historical workings. | |||
| Surface lag sampling was conducted over transported cover areas so is considered to be largely ineffective, however several anomalies were | |||
| returned near old workings. Surface soil sampling (-2mm) identified 12 areas anomalous for Au in the central part of the Project with +10ppb Au | |||
| being used as a contouring threshold. Some prospecting of possible pegmatite locations was undertaken, however potential was downgraded | |||
| following the reconnaissance work. | |||
| • 3D Resources & Cosmo Gold ~2007-2024– upon unification of the Project in its current form, the group undertook substantial data compilation | |||
| works while Native Title access agreements were negotiated. Several tranches of aeromagnetic interpretation and targeting were completed for | |||

| mineralization. | the Eastern Goldfields of Western Australia. The Cosmo Newbery Project is located ~50–95 km west of significant exploration and mining activity on | ||
| adjacent greenstone belts being that are of a similar geological setting. | |||
| The Cosmo Greenstone Belt is traversed by the regional north-northwest trending Sefton Shear Zone and other major margin faults. The Sefton Fault | |||
| truncates the greenstone belt to the west and is interpreted to dip to the west-southwest and has an inferred strike length of over 120km. The eastern | |||
| margin of the Cosmo Greenstone Belt is a fault boundary, which is probably a splay off the Sefton Fault, and is also interpreted to dip to the west- | |||
| southwest with a steep dip near surface and flattening off at depth. | |||
| The majority of the greenstone belt (~75%) is obscured by colluvium and sand cover which precludes detailed surface mapping. The outcropping area of | |||
| the belt is restricted to an ~18km x 8km area immediately north and south of the Cosmo Newbery township. The dominant outcropping lithology is | |||
| metabasalt with subordinate high-Mg basalt, metagabbro, ultramafic and felsic volcanics. The ultramafic lithologies are tremolite-chlorite, tremolite- |
19
| chlorite-talc and actinolite-chlorite assemblages that likely represent thin komatiite or komatiite basalt flows. A ~4.5km long x 0.5–1.0km wide ultramafic talc chlorite schist along a portion of the western greenstone contact had been mapped. Aeromagnetic images indicate this ultramafic unit extends beneath cover to the north for an additional 13km and thickens to ~1.5km some 10km northwest of the township. Reports of laterite covered ultramafic west of the township and mapped ultramafic outcrop in the north and recently observed “calcareous and chalcedonic ultramafic cap rocks” (near the western contact of main internal granite) indicate ultramafics occur elsewhere in the project area. At least four large internal Archaean granitoids are interpreted including a prominent 15km long x 3.5km wide north-northwest ovoid foliated porphyritic biotite monzogranite in the central area. The close spatial association of known gold occurrences on the west and north margins and extending north of this monzogranite indicates a potential mineralisation control. Historical gold workings (shallow shafts and pits with strike lengths of <100m) occur in the area of well-exposed greenstone lithologies immediately north of the township, usually presenting as narrow mineralised shears, usually <1 - 1.5m wide and infilled with thin quartz veining, associated with mafic/felsic schist contacts. The mineralised shears are predominantly within basalt, but also within a highly silicified felsic volcanic host rock. |

| 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 hole length. In H1 1995, approximately 3,001m RAB drilling (in 223 holes to average depth 13m, median depth 9m and maximum depth of 45m) was completed at the Project. Holes were drilled at -60° inclination and seemingly at 090° MN azimuth. Collar elevation recorded as a uniform 400m (unknown datum). Overall, the data obtained by the drill program is deemed to be of low reliability with several issues present including low accuracy in drill collar co- ordinates (unknown/ambiguous grid references) and as a result, no Exploration Results are being reported for this drilling. |
| 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. A tabulation of all Material drill holes has not been provided as the drilling has been deemed to be unreliable and no associated Exploration Results are being reported. This exclusion is not considered Material nor does it detract from the understanding of other exploration programs conducted at the Project that are being reported as Exploration Results. |

| Data Aggregation Methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Drilling- no Exploration Results are being reported for drilling. Geochemical Surveys– summary statistical results are reported. |
| 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. Drilling- no Exploration Results are being reported for drilling. |

| The assumptions used for any reporting of metal equivalent values should be clearly stated. Drilling- no Exploration Results are being reported for drilling. Geochemical Surveys– no metal equivalent values are being reported. |
