Scamander Base Metals and Tin Advanced Exploration Project

Scamander EL19/2020

The Scamander district is a regional NW-SE trending mineralised corridor including;

  • The North Scamander prospect
  • The Pinnacles prospect
  • The Great Pyramid (historic tin mine and JORC resource of 5.2Mt @ 0.22% Sn to 46m on TORC RL2/2009)
  • Other prospects

These advanced exploration prospects (other than Great Pyramid held by Tin One Resources Corporation (TORC)), are all held by Stellar on EL19/2020, located approximately 10km northeast of Scamander, in Northeast Tasmania.

The Scamander district contains a large number of metallic mineral occurrences hosted within folded and faulted Ordovician Mathinna Group sedimentary rocks and is underlain by a strongly fractionated alkali granite. The metalliferous nature of the district, well defined metal zonation and location above the inferred alkali granite suggest that known mineralisation in this area is spatially and genetically associated with the emplacement of the fertile granite.

Significant historic exploration for tin and base metals has been undertaken on Stellar’s EL19/2020 including extensive soil sampling, stream sediment sampling and drilling defining areas of anomalous Sn, Zn, Cu, Ag and Pb mineralisation at the North Scamander, Pinnacles and other prospects.

Significant W, Sn, Cu and Zn anomalies are defined by stream sediment geochemistry which define a regional scale NW-SE trending mineralised corridor which includes the Pinnacles and North Scamander tin-base metals projects on EL19/2020, extending to the NW and SE of the Great Pyramid mine.

Magnetic Inversion Modelling & Exploration Targets

Magnetic inversion modelling undertaken by Stellar’s geophysical consultant has shown that historic drilling at North Scamander was not deep enough to intersect the core of the magnetic feature which represents a high potential drilling target. Whilst the Pinnacles prospect is characterised by a more subtle magnetic feature, its strong surface geochemical anomalies, mapped sheeted quartz-cassiterite veins and historic drilling results combine to make the Pinnacles prospect another high potential drilling target.

North Scamander Base Metals-Tin Target (EL19/2020)

The North Scamander tin-base metals project is characterised by an outcropping mineralised gossan, that has generated strong surface stream sediment and soil tin geochemistry anomalies over the prospect and corresponds with a significant aeromagnetic anomaly. Rock chip samples from the prospect return grades of up to 1.07% Sn.

Historic Drilling over the North Scamander target completed in 1981 includes 4 shallow percussion and 4 diamond drillholes to approximately 250m depth which intersected intervals of pyrrhotite-cemented hydrothermal breccia associated with intense magnetite alteration of the wall rocks and strongly anomalous Sn, Cu and Zn values. Historic drilling results include:

NSD001

  • 05m @ 0.2% Zn and 5 g/t Ag, from 11.40m
    • 15.41m @0.1% Sn, 0.2% Cu, 0.8 % Zn, 0.1% Pb and 25 g/t Ag, from 163.04m

NSD002

  • 45m @ 0.8% Zn and 12 g/t Ag, from 31.35m
    • Inc 1.21m @ 0.9% Sn, 3.4% Zn, 1.5% Pb and 28 g/t Ag, from 110.50m
    • And 6.05m @ 0.1% Sn, 2.7% Zn, 1.7% Pb and 30 g/t Ag, from 136.37m
    • And 9.15m @ 0.2% Sn, 2.1% Zn, 0.8% Pb and 38 g/t Ag, from 148.90m

NSD003

  • 5m @ 0.16% Zn and 2 g/t Ag, from 18.80m

NSD004

  • 4m @ 0.2% Cu, 0.2% Zn, 0.2% Pb and 21 g/t Ag, from 224.30m

Pinnacles Sn-Base Metals Target (EL19/2020)

The Pinnacles tin-base metals project is characterised by widespread outcropping sheeted quartz-cassiterite veins which are likely responsible for the strong surface stream sediment and soil tin geochemistry anomalies over the prospect and corresponds with a low intensity aeromagnetic anomaly. Limited rock chip samples are available over the prospect

Historic drilling over the Pinnacles target completed in 1983 includes 12 RC holes to a maximum depth of 120m targeting a large Sn soil anomaly, related to the sheeted quartz-cassiterite veins mapped at surface. Sn grades up to 0.4% over a length of 1.0m were reported in drillhole PPH1, with holes either side also returned anomalous Sn.

Tasmanian Government Co-funded Exploration Drilling Grants totalling $83,750 were awarded to Stellar’s wholly owned subsidiary, Tarcoola Iron Pty Ltd in August 2022 to drill North Scamander and Pinnacles targets on EL19/2020 in 2023.
