Caspin Resources Limited (Caspin or the Company) (ASX: CPN ) is pleased to provide an update on exploration activities at the Bygoo Tin Project in New South Wales. The Company is making rapid progress at the Kelpie Tin Deposit where drilling has been underway for several weeks aiming to grow the Kelpie resource. In parallel, the Company has developing targets at the Ardlethan East Prospect ready for reconnaissance-style drilling.

Induced Polarisation Survey Provides New Insights to Mineralisation
The Company completed an Induced Polarisation (IP) survey early in February 2026, to assist subsurface mapping and drill targeting of the prospective granite contact. IP measures chargeability, which typically relates to the presence of disseminated sulphides, and resistivity, commonly a response of silica alteration. Both responses have the potential to be associated with tin greisen-style mineralisation systems.
The survey has clearly highlighted NE-SW trending and NNE trending chargeability and resistivity anomalies (Figure 1). These anomalies coincide with mineralisation at the historical Dumbrells workings as well at the ‘Stewarts Zone’ to the northwest. Historical workings in the Kelpie area also tend to be aligned along similar NE and NNE trends, leading to the conclusion that these IP anomalies are likely to be mapping fault structures which have acted as fluid pathways for mineralisation. The strongest mineralisation is anticipated at the intersection of these NE-SW and NNE trending faults and the Ardlethan Granite contact (Figure 1), which is likely to be a structural boundary within the regionally extensive, NNW-trending Cobar-Wagga Shear. Such intersections of major fault systems provide a mechanism for concentrating fluid flow and subsequent mineralisation.
RC drilling is progressing steadily, with 23 holes for approximately 4,000m drilled to date. All assays remain pending. The IP survey has allowed the Company to refine the drilling program to ensure that drilling is oriented approximately perpendicular to those structures imaged by the IP, rather than targeting the granite contact alone, with the objective extending mineralisation along these trends (Figure 2 & Table 1, Appendix A). It should be noted that mineralisation is also observed beyond these IP anomalies, possibly in unrecognised subsidiary structures, indicating additional opportunities to grow the resource.

Figure 1. Kelpie Deposit IP chargeability and resistivity results and interpretation.
The IP survey was co-funded by the NSW Government Critical Minerals and High-Tech Metals Exploration Program, providing a cheap, low-risk opportunity to trial a potentially critical technology to assist exploration. The results from the survey have validated this approach and because mineralisation (eg historical workings, anomalous rock chips) is also recognised outside the area of the IP survey, the company now intends to extend

this survey significantly. In particular, the area to the north of the current Kelpie resource is considered highly prospective, with significant anomalism and historical workings recognised at the “Area 1” target.

New Targets Emerging at Ardlethan East
First soil geochemistry results have now been received from the Ardlethan East area and have presented targets for immediate drill testing. Approximately 350 samples have been returned with a further 800 samples still pending. Further areas to the south of Ardlethan are scheduled for sampling in the coming weeks.
The Ardlethan East area is highly prospective, located within a short distance of the Ardlethan Mine which produced over 31,000t of tin in concentrate until 1986 from both open pit and underground mines. Significant alluvial production also occurred from the Yithan Lead which cuts through the prospect area. Key structures that facilitate mineralisation at Ardlethan continue into Caspin’s tenure at Ardlethan East. The area is
==> picture [299 x 72] intentionally omitted <==

==> picture [104 x 32] intentionally omitted <==
prospective for both breccia-style (Ardlethan-style) and greisen-style (Kelpie-style) mineralisation, which may be potentially subcropping, or concealed under shallow lithological cover. An illustration of these mineralisation models is shown in Figure 3.
==> picture [483 x 340] intentionally omitted <==
Figure 3. Schematic diagram of mineralisation styles within the Bygoo Project
Fundamental to all styles of mineralisation are major fault structures, in this case, a splay of the Cobar-Wagga shear, which appears to be key to mineralisation at Ardlethan as well as the Yithan Lead, and the interplay with NE-SW cross-cutting faults. The faults are recognised in Caspin’s high-resolution aeromagnetic survey and are often associated with surficial mineralisation and historical prospecting/mining.
The results received thus far show multiple areas of tin anomalism, often associated with fault structures, supported by pathfinder elements common in hydrothermal tin mineralisation, including Sb, Cu, Pb, Zn, Ag, In and Bi. Some of the anomalism is on the edge of the survey, which will be delineated with further sampling. The strongest area of anomalism is approximately only 500m from the edge of the Ardlethan pit (Figure 4).
Further support is provided by rock chip sampling, with numerous outcrops returning significant values of tin (>250ppm) and accessory metals (Table 2, Appendix A). The highest rock chip grades of up to 3.78% Sn have been returned from a historical mining area known as Ford’s Gossan, where the Company is still anticipating the return of soil geochemistry. Other samples have returned values of 2.01% Sn, 1.77% Sn & 1.16% Sn .
Ardlethan-style breccia pipes can have relatively small horizontal footprints, in the order of several hundred meters in diameter, but can be vertically extensive. Within the pipe, Sn mineralisation represents a relatively small volume of the total pipe-like complex. Alteration halos with mixed metal signatures of Cu, Pb, Zn, Sb & As may be far broader. Therefore, small anomalies on the scale of the geochemistry program may be significant, particularly if there is associated metal anomalism and/or a conducive structural setting.

The Company is mobilising the RC rig to drill test some of these anomalies immediately.
This early-stage exploration at Ardlethan East is a key part of the Company’s strategy to recognise the full potential of the Bygoo Project with over 20km of prospective strike, which the Company believes can host multiple, large, high-grade open pit deposits. With the effectiveness of soil geochemistry demonstrated, combined with magnetics, gravity and increasingly with IP, the Company is now looking to expand coverage across the Bygoo Project area.

ABOUT CASPIN:
Caspin Resources Limited (ASX Code: CPN ) is a mineral exploration company based in Perth, Western Australia, with expertise in early-stage exploration and development. The Company currently has four Australian projects offering a diverse mix of commodities and excellent opportunity to add value through exploration and discovery.
-
The Company’s flagship project is the Bygoo Project in New South Wales, an advanced, high-grade tin project located in a prolific Wagga tin belt. The project surrounds the Ardlethan Mine, one of Australia’s largest producing tin mines on mainland Australia before it closed in 1986. The Company recently announced its maiden Inferred Resource Estimate of 3.94mt @ 0.5% Sn for 19,300t of contained tin.
-
The Company has recently acquired an option to earn 80% of the Weethalle Project in NSW, a
==> picture [273 x 247] intentionally omitted <==
-
short distance north of the Bygoo Project. The Project is prospective for large-scale intrusive related gold mineralisation, with a structural setting similar to the Hemi deposit in Western Australia. Compelling geophysical and geochemical anomalies have never been drill tested.
-
The Yarawindah Brook and Mount Squires Projects are new frontier projects located in WA and prospective for Ni-Cu-PGE sulphide mineralisation. Both projects are located in frontier magmatic sulphide provinces with large scale deposits nearby. The Company believes these projects have long-term strategic value and is pursuing avenues to advance alongside its NSW assets.
These projects are strategically positioned in Australia’s premier mineral districts, providing excellent exposure to new critical and technology mineral markets.

ANNEXURE 1:
The following Tables are provided to ensure compliance with the JORC Code (2012) edition requirements for the reporting of the Exploration Results at the Weethalle Gold Project.
SECTION 1: Sampling Techniques and Data (Criteria in this section apply to all succeeding sections)
| CRITERIA | JORC CODE EXPLANATION | COMMENTARY | |
|---|---|---|---|
| Sampling techniques |
Nature and quality of sampling (eg 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. |
Soil sampling: Surface soil samples were collected on east-west orientated lines at a default 100m spacing with alternating lines offset by 50m. Samples were collected by digging a 30x30x20cm pit, cleaning the base of the pit out before homogenising the sample. The sample was immediately sieved to 80# or 177 microns, approximately 400g was collected. Rock Chip sampling: Samples of outcrop were collected via a geopick at irregular intervals where encouraging outcropping geology was encountered. |
|
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Soil & Rock Chip sampling: Sampling has been carried out using standard protocols and QAQC procedures as per industry best practice. Soil and rock chip sampling locations were surveyed by handheld GPS units which have an accuracy of ±5m. |
||
| 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 (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 mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
Soil sampling: Samples were transported to Brisbane ALS for pulverising (PUL-31L) and 4-Acid digest analysis via the ME-MS61L method Rock Chip sampling: Samples detailed in this report were transported to ALS Brisbane and pulverised to <75µm (PUL-23) prior to ME-MS89L ICP-MS and ICP-AES Fusion Multi Element and Au-ICP-21 Au analysis. |
||
| 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). |
Not applicable as no drill results are reported in this announcement. |

| assaying | continuing. | |
| The use of twinned holes. | Not applicable as drill results are not discussed in this announcement. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Sample locations, sample data and geological information for drill holes were recorded in field logging computers. Data was then sent to the company database managed by MRG Data. |
|
| Discuss any adjustment to assay data. | No adjustments were made to assay data. | |
| 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. |
Soil and rock chip sample locations were recorded using a handheld Garmin GPS which typically have a ±5 metre accuracy. RL Data from handheld GPS is typically unreliable and was instead sourced from GIS software utilising imported DTM elevation layers. |
| Specification of the grid system used. | The grid system for the Bygoo Project is GDA2020 MGA Zone 55. |
|
| Quality and adequacy of topographic control. | Topographic data was obtained from public download of the relevant 1:250,000 scale map sheets. The area exhibits subdued, low relief. Topographic representation is considered sufficiently controlled. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | Rock Chips sample locations are spaced irregularly. Surface soil samples were collected on east-west orientated lines at a default 100m spacing with alternating lines offset by 50m. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appr_opriate_for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
Not applicable as no Mineral Resource and Ore Reserve reported. |
|
| Whether sample compositing has been applied. | No sample compositing has occurred. | |
| 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. |
Soil sampling is conducted on a pre-defined grid pattern and introduces no bias to geological structures. Rock chip samples are collected ad-hoc at outcrop exposures and may unintentionally focus on structures which focus alteration and mineralisation. |
| 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. |
Not applicable as no Mineral Resource and Ore Reserve reported. |
|
| Sample security | The measures taken to ensure sample security. | Samples were collected on-site by Caspin staff and transported via third-party freight contractors to Orange and Brisbane. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
Company geologists continue to review the data, no external reviews have been completed. |

|
| 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 Bygoo Tin project comprises of three Exploration Titles, EL8260, EL9288 and EL9234. The Titles cover a combined area of 1,183km² and are now 100% held by Caspin Resources. The Ardlethan Tin Mine is excised from EL8260 and is not held by Caspin Resources. |
|
| 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. All Titles are currently live and in good standing. No Mining Agreement has been negotiated. |
|
| Exploration done by other parties Acknowledgment and appraisal of exploration by other parties. Prospecting and small-scale artisanal mining occurred across the Bygoo Project following the discovery of the Ardlethan tin mine in 1912. RAB drilling testing for extensions of the Ardlethan mine was conducted from 1961 until 1962, followed by sporadic programs of further RAB and percussion drilling between 1977 and 1982 testing for blind alluvial occurrences and extensions of small-scale workings including the Bald Hill, Taylors, Killarney, Big Bygoo and Bygoo North occurrences. Drilling completed by Thomson Resources from 2015 to 2022 represents the first period of sustained modern exploration. |
|
| Geology Deposit type, geological setting and style of mineralisation. The Bygoo Project is located within the Lachlan Fold Belt of NSW and part of the ‘Wagga Tin Belt’, a 320 x 80km belt of late Silurian granitoids extending from the towns of Wagga Wagga to Condobolin. Granites carry a background enrichment of 10ppm Sn and host the greatest known endowment of tin within the Australian mainland. Locally, the Ardlethan granite intrudes Ordovician sediments with known mineral occurrences concentrated on the eastern margins of this contact. The best understood mineralisation models on the project are a breccia-pipe porphyry at the Ardlethan Mine, and greisen-style at Bygoo North. Extensive alluvial mineralisation has also been found across the project. Cassiterite hosts tin mineralisation. Trace copper, lead, zinc, bismuth, antimony and silver are noted accessory metals. |

|---|---|
| • 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. Only significant Rock Chip results are reported, with a >250ppm Sn cutoff applied. Results of individual Soil Samples are not considered material in nature. |
|
| 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. Rock Chip samples above 250ppm Sn 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. No data aggregation has been applied to Rock Chip results. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalent values are reported. |
|
| 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’). Drill collars were spaced irregularly as first-pass tests of interpreted geological structures and geophysical anomalies. The exact orientation of structures and their true widths is unknown. |
| 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 Figures in body of text. |
| 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. Only significant results have 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. All currently relevant exploration data is detailed in text, Figures, Table 1 and Annexure 1. |
| Further work | The nature and scale of planned further work (eg 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. Caspin’s upcoming work program includes: • Further RC drilling • Further IP Surveys • Further soil sampling • Ground Gravity surveys |
