Highlights

  • Caspin Resources reported an updated Mineral Resource Estimate of 6.5 million tonnes grading 0.43% tin at Kelpie, containing approximately 28,000 tonnes of tin.
  • The October 2026 resource update represented a 45% increase in contained tin compared with the previous estimate, supported by additional drilling.
  • Cash holdings stood at approximately AUD 5.5 million at 30 September 2026, while further drilling and technical investigations remain important to the project's development.

Caspin Resources Limited (ASX:CPN) is an Australian mineral exploration company focused on identifying and evaluating mineral deposits, including tin and base metals. Its principal tin exploration activities are centred on the Bygoo project in New South Wales, where the Kelpie deposit forms an important part of its mineral resource inventory. On 12 October 2026, the company announced an updated Mineral Resource Estimate for Kelpie following additional drilling, providing a larger defined resource base for further technical assessment.

What Changed in the Kelpie Tin Resource Estimate?

Caspin Resources reported an updated Mineral Resource Estimate of approximately 6.5 million tonnes grading 0.43% tin, equivalent to around 28,000 tonnes of contained metal.

The revised estimate represented a 45% increase in contained tin compared with the previous resource assessment.

The update incorporated additional drilling information, improving the company's geological understanding of mineralisation at Kelpie.

The reported resource includes both Indicated and Inferred classifications, reflecting different levels of geological confidence.

Approximately 1.4 million tonnes grading 0.47% tin were classified as Indicated, while approximately 5.1 million tonnes grading 0.41% tin were classified as Inferred.

For Caspin Resources (ASX:CPN), the increase provides a larger mineral resource inventory that can be assessed through subsequent exploration and technical studies.

However, a Mineral Resource Estimate does not establish an economically recoverable Ore Reserve or confirm that a Mining operation will proceed.

Further Drilling and Metallurgical Work Remain Important

The Kelpie resource update follows exploration activities across the broader Bygoo project.

Additional drilling has been undertaken to investigate mineralisation and improve geological interpretation within selected target areas.

The company has also reported tin mineralisation at other prospects within the project, indicating opportunities for further exploration.

Preliminary metallurgical investigations have examined the characteristics of tin-bearing material and potential recovery methods.

These studies provide information for evaluating possible processing approaches, although laboratory results cannot be assumed to represent future commercial performance.

For Caspin Resources (ASX:CPN), further drilling could help refine the resource model, assess extensions and potentially improve confidence in areas currently classified as Inferred.

Additional metallurgical, environmental and engineering investigations would also be necessary before progressing towards more advanced development assessments.

FY2026 Financial Performance and Exploration Expenditure

Caspin Resources reported a statutory net loss of approximately AUD 5.70 million for FY2026, compared with approximately AUD 2.59 million in FY2025.

The increase reflected higher exploration expenditure and other corporate costs during the financial year.

Exploration expenditure recognised in the income statement totalled approximately AUD 4.31 million, consistent with the company's accounting treatment of expensing exploration activities as incurred.

At 30 June 2026, Caspin Resources held approximately AUD 7.06 million in cash and cash equivalents.

By 30 September 2026, cash holdings had declined to approximately AUD 5.5 million as exploration activities continued.

The September quarter included approximately AUD 1.79 million in net operating cash outflows, with a substantial portion associated with the Bygoo project.

Caspin Resources (ASX:CPN) reported an estimated funding runway of approximately 3.1 quarters based on the relevant expenditure measures in its quarterly cash flow statement.

What Risks Remain Following the Resource Upgrade?

Although the Kelpie update increased contained tin, a substantial proportion of the resource remains classified as Inferred.

Inferred Mineral Resources carry a lower level of geological confidence than Indicated resources and require additional supporting information before they can be considered for conversion into Ore Reserves.

The company has not established commercial production at Kelpie, and further studies would be required to assess the economic viability of potential development.

For Caspin Resources (ASX:CPN), Commodity price fluctuations, future drilling results, processing recoveries and development costs remain important uncertainties.

The company's exploration-stage operations also require ongoing expenditure without established mining revenue.

Additional funding may be required to support future technical investigations and project development activities.

What Could Shape Caspin Resources' Next Exploration Phase?

The updated Kelpie resource provides a foundation for further assessment of the Bygoo project.

Planned exploration activities include additional drilling to investigate potential mineralisation extensions and improve geological confidence.

Further work at surrounding prospects could also help determine whether additional mineralised zones Warrant more detailed investigation.

Metallurgical studies and environmental assessments may provide information relevant to future development options.

For Caspin Resources (ASX:CPN), the next stage will depend on exploration outcomes, technical results and the availability of funding to support continued work.

Key Insights

Caspin Resources' Kelpie resource upgrade increased contained tin by 45%, providing a larger defined mineral inventory at the Bygoo project. However, most of the resource remains in the Inferred category, and further drilling and technical studies are necessary before development feasibility can be assessed. Cash expenditure, tin market conditions and future exploration results will remain important considerations.

Editorial verification note: Caspin's official project information confirms the October 2026 Kelpie resource estimate of 6.5 million tonnes at 0.43% tin, containing 28,000 tonnes, and the 45% increase in contained metal. It also confirms the Indicated and Inferred resource classifications.
