Stellar Resources has reported exceptional surface sampling results from its East Renison Project in Tasmania, revealing high grades of silver, tin, antimony, gold, and critical minerals including indium. A government-supported drilling program is set to test promising targets, underscoring the project's growing strategic importance.
- Surface samples returned up to 3,550 g/t silver and 14.7% antimony
- High-grade polymetallic mineralisation includes tin, gold, lead, zinc, copper, and indium
- Drilling planned at Carbine Hill, co-funded by Tasmanian government grant
- East Renison Project borders world-class Renison Tin Mine
- Results reinforce potential for a significant polymetallic system complementing Heemskirk Tin Project
Exceptional Surface Sampling Highlights East Renison’s Potential
Stellar Resources Limited (ASX – SRZ) has unveiled striking results from recent surface grab sampling at its East Renison Project in Tasmania. The assays revealed extraordinarily high concentrations of silver, antimony, tin, gold, and base metals, with peak values including 3,550 grams per tonne (g/t) silver and 14.7% antimony. Notably, samples also contained significant lead, zinc, copper, and the critical mineral indium, which is vital for modern electronics such as liquid crystal displays.
These findings come from reconnaissance sampling across a roughly 3km by 3km mineralised zone adjacent to the Renison Tin Mine, one of the world’s most renowned tin deposits. The East Renison Project covers key structural continuations of the Federal-Bassett and Montezuma Faults, known for hosting polymetallic mineralisation.
Strategic Drilling to Test High-Grade Targets
Building on these surface results, Stellar plans a diamond drilling program at Carbine Hill, targeting a vein-hosted tin-polymetallic system identified by a coincident electromagnetic anomaly. This drilling is supported by a $55,000 co-funding grant from Tasmania’s Exploration Drilling Grant Initiative (EDGI), reflecting government confidence in the project’s potential.
Managing Director Simon Taylor emphasised the significance of the results, noting the diversity and grades of mineralisation point to a substantial polymetallic system. He highlighted the project’s strategic location adjoining the Renison Tin Mine and its complementarity to Stellar’s nearby Heemskirk Tin Project, which is among Australia’s highest-grade undeveloped tin resources.
Critical Minerals and Future Exploration Plans
Of particular interest is the detection of indium at levels exceeding 500 parts per million in three samples. Indium is classified as a critical mineral by the US Geological Survey and is essential in high-tech applications. Samples have been sent to ALS in Vancouver for detailed analysis, with results expected shortly.
Stellar is advancing further exploration activities including detailed geophysical surveys, mapping, and additional sampling to refine targets ahead of drilling. Historical drilling within the project area has already returned promising tin intersections, reinforcing the prospectivity of the region.
With the East Renison Project emerging as a polymetallic hub rich in tin and critical minerals, Stellar Resources is positioning itself to enhance its footprint in Tasmania’s mining landscape and progress towards its ambition of becoming a top global tin producer.
Bottom Line?
As Stellar Resources prepares to drill, the market will watch closely for confirmation of these high-grade polymetallic systems that could reshape its growth trajectory.
Questions in the middle?
- Will the upcoming Carbine Hill drilling confirm the extent and continuity of the polymetallic mineralisation?
- What are the detailed assay results for indium, and how might this impact the project’s strategic value?
- How will these new findings influence Stellar’s development timeline and resource estimates at East Renison?
