“The ZS143W results, together with the results from parent hole ZS143 and phase 1 ZS140, highlight the potential for significant expansion of the Severn resource at depth. Severn is already by far the largest of the four deposits in the Heemskirk Tin Project and remains open at depth and laterally,” says the manager.
Stellar Resources Ltd (ASX:SRZ) has intersected high-grade tin in a wedge hole (ZS143W) at the Severn deposit – one of four deposits in the company’s flagship Heemskirk Tin project.
The Heemskirk project on the west coast of Tasmania is the highest quality undeveloped tin resource in Australia and the second highest in the world.
Results from the first phase of drilling at the deposit have confirmed extensive zones of high-grade tin mineralization, with a remarkable 20 meter stacked tin mineralization intersected approximately 600 meters below surface. Key tests include:
- 3.8 meters at 1.10% tin from 585 meters;
- 3.0 meters at 1.31% from 635 meters; and
- 8.4 meters at 0.73% from 650.7 meters.
These intersections demonstrate continuity of mineralization from the bottom of the inferred resources of the Severn deposit, confirming that Severn remains open at depth and laterally.
Potential for increased resources
“The assay results from daughter hole ZS143W are very encouraging and significantly demonstrate the continuity of tin mineralization between drill hole ZS120 above and parent hole ZS143 below,” said the executive director of Stellar Resources, Gary Fietz.
“The ZS143W results, together with the results from parent hole ZS143 and phase 1 ZS140, highlight the potential for significant expansion of the Severn resource at depth.
“Severn is already by far the largest of the four deposits in the Heemskirk Tin Project and remains open at depth and laterally.”
Drilling at the Oonah deposit, the historic Zeehan Western mine and the historic Zeehan Queen No 4 mine have all intersected additional tin mineralization.
The results confirmed several low grade zones below Oonah, high grade narrow fissures below Zeehan Western and sulphide mineralization with anomalous tin below Zeehan Queen No 4.
Extension-focused Phase 2 drilling
“The last of our Phase 1 holes (ZS148) targeting extensions of the Indicated Mineral Resource at Severn is well advanced and should be completed within a few weeks,” continued Fietz.
“The second rig on site recently began drilling the first hole of the Phase 2 drill program at Severn.
“The initial Phase 2 program in 2022 will focus on extending the Severn Indicated Resource as well as a planned deeper hole at South Severn to test the compelling magnetic and conductivity target identified last year.
“We are currently finalizing hole designs for the Phase 2 program and will update the market shortly.”
The first hole of the Phase 2 program at Severn began drilling last Friday, targeting infill drilling to better define extensional tin mineralization and test drilling of the South Severn magnetic and conductivity target at 900 meters depth.
