East Renison Project

Covering a total area of 35km², Stellar’s East Renison Project is comprised of two contiguous exploration licences, the Concert Creek licence (EL29/2022) and the Ringville licence (EL9/2025), located adjacent to the Renison Tin Mine – Australia’s largest producing tin mine – in the stable tier-1 mining friendly jurisdiction of western Tasmania.

Geologically, the East Renison Project area comprises strongly foliated Precambrian sandstones and shales, grouped as the ‘Concert Schist’. This is overlain by a package of dolomites, conglomerates or ‘tillites’, dolomitic siltstones, slates and sandstones, considered equivalents to the Success Creek Group (‘Mine Series’ and main host to mineralisation at Renison). The rest of the sequence is comprised largely of volcanics and volcaniclastics of the Mount Read Volcanics, which host VMS style mineralisation at nearby Rosebery.

Modelling conducted by Mineral Resources Tasmania  (MRT) using jointly inverted magnetics and gravity indicate the Pine Hill Granite at depths ranging from 500m to 2km, which is considered an ideal window for exploration for sulphide-hosted Tin systems.

Preliminary structural interpretation of the magnetics and gravity suggest a high degree of structural complexity above the eastern margin of the Pine Hill Granite. Historically mapped vein-hosted Antimony – Copper – Bismuth – Tin (Sb-Cu-Bi-Sn) mineralisation suggests two major mineralised structural corridors that strike approximately northeast but wrap into cross cutting northwest trending faults associated with the Federal-Bassett Fault that is the principal control on the location of the Renison Tin Mine.

Drilling in the 1980’s at the Godkin Prospect (Figure 2) intersected high grade tin mineralisation including:

• 1.5 metres @ 6.9% Sn from 87m in historical hole GDK4 and
• 3.0 metres @ 1.5% Sn from 209m in historical hole GDK5. 

Recent sampling work by Stellar on the Concert Creek licence has identified high grade Antimony with four of 20 samples collected returning over 0.1% Sb and up to 6% Sb with samples anomalous in Antimony, Copper, Zinc, Lead, Bismuth and Silver highlighted in the map below. Copper grades up to 4.6% Cu and Lead up to 9.5% Pb were also reported.
