Highlights
- Stellar Resources reports a record high-grade tin intersection at the Heemskirk Tin Project.
- Current drilling program focuses on resource expansion and prefeasibility studies.
- Results show significant mineralisation with higher grades than predicted in the resource model.
Stellar Resources (ASX:SRZ) has unveiled remarkable results from its ongoing drilling program at the Heemskirk Tin Project in Western Tasmania. The company announced a record high-grade tin intersection of 20.9 metres at 1.97% tin from the Severn deposit, marking a major milestone in its exploration efforts.
The ongoing drilling program includes 24 holes spanning approximately 9,500 metres, with a focus on infill and extensional drilling at the Severn and Queen Hill deposits. To date, eight holes covering over 3,600 metres have been completed. Stellar Resources is conducting this campaign to support its prefeasibility study, which aims to evaluate the potential of Heemskirk as a long-life tin operation.
Drilling Results Highlight Record Mineralisation
The highlight of the program so far is drillhole ZS166, which returned multiple high-grade tin zones, including:
- 20.9 metres at 1.97% tin from 431.0 metres, featuring 14.8 metres at 2.40% tin from 437.1 metres and 5.9 metres at 3.36% tin from 437.1 metres.
- 4 metres at 1.67% tin from 510 metres.
- 6 metres at 1.63% tin from 522 metres.
- 5 metres at 1.70% tin from 533 metres, including 1 metre at 7.34% tin from 533 metres.
These intersections fall within the inferred resource category of the 2023 Mineral Resource Estimate and significantly exceed the grades and thickness predicted by the resource model. The mineralisation at Severn remains open down plunge, with the nearest drillhole located 145 metres further down dip.
At Queen Hill, drillhole ZQ165 confirmed a northern extension for follow-up, returning 4 metres at 0.52% tin from 310 metres.
Next Steps in Development
Stellar Resources plans to deploy a geophysical crew in December for fixed-loop surface and downhole electromagnetic surveys at Severn and Queen Hill. The company also aims to upgrade inferred resources to the indicated category and explore for further extensions of the mineralised system.
The prefeasibility study, along with baseline environmental studies, is progressing well, with updates expected in the coming months. The recent scoping study outlines a base case 10-year mine life using only indicated resources, which the company anticipates expanding in the 2025 resource update.
Stellar Resources continues to focus on delivering further results to strengthen its case for Heemskirk as a world-class tin operation.
