 Outstanding Wide High-Grade Intersection at Queen Hill
Key Points
  • Drillhole ZQ173 intersected 23.3m @ 2.20% Sn including 4.2m @ 3.76% Sn and 3.9m @ 3.45% Sn
  • Mineralisation remains open down dip and plunge
  • DHEM surveying indicates a conductive body along strike and to the south
Full Summary

Stellar Resources Limited (ASX: SRZ) reported further drilling results from the Queen Hill and Severn deposits at its Heemskirk Tin Project in Western Tasmania. Drillhole ZQ173 at Queen Hill intersected a wide high-grade zone of 23.3m @ 2.20% Sn from 295.7m, including 4.2m @ 3.76% Sn and 3.9m @ 3.45% Sn. This intersection is located within an Inferred region of the Mineral Resource and should allow for the conversion of mineralisation to the Indicated category for the ongoing Prefeasibility Study (PFS). The hole also returned multiple tin zones further downhole in the lower Queen Hill horizon. Significantly, Down Hole Electromagnetic (DHEM) surveying of hole ZQ173 indicates the presence of a conductive body along strike and to the south of the intersection on the lower horizon. Mineralisation remains open down dip and plunge, and further drilling will test for extensions to this wide zone of mineralisation. Hole ZQ171 at the northern end of Queen Hill returned a narrow intersection of 1m @ 0.8% tin, indicating the system continues to the north. At the Severn deposit, hole ZS164A intersected multiple mineralised zones, providing further support for the conversion of Inferred mineralisation to the Indicated category. The drilling program is designed to advance Heemskirk to development-ready status by providing key technical inputs for the PFS, while also aiming for mineral resource expansion.

Guidance

Stellar aims to be a 3,000 to 3,500 tpa tin producer over the first 6 to 10 years of production. The PFS studies are working towards this by improving upon the base case scoping study of 1,900 tpa over a 12 year mine life.

Outlook

Drilling continues with three rigs operating, and the Company is now starting to model the first results from down hole electromagnetic surveys to help guide further drilling as it looks to bolster the resource to be updated as part of the Prefeasibility Study.
