Stellar Resources Limited (ASX:SRZ, "Stellar" or the "Company") is pleased to announce that under Round Eight of the Exploration Drilling Grant Initiative (EDGI) program, the Tasmanian Government has awarded the Company four exploration drilling co-funding grants totalling $258,500 for exploration drilling of the North Scamander, Carbine Hill East, Evenden, and Razorback tin-base metals-critical minerals targets.
The grants awarded to Stellar are for the following exploration projects:
- North Scamander Sn-base metals-critical minerals target EL19/2020 ($70,000 grant) One diamond drill hole (750m) planned to test the core of a regional scale magnetic anomaly, approximately 125m down dip of historic drilling hydrothermal breccia intersections with strongly anomalous tin, lead, zinc, and silver values. The primary target (~375m depth) is higher grade breccia hosted or sheeted vein mineralisation containing tin, silver, lead, zinc (+/-) indium near the core of the magnetic anomaly. The hole will also continue past the primary target to also test the roots of the breccia-hosted mineralisation, targeting greisen style mineralisation which may occur near the underlying inferred granite margin where tin, tungsten, lithium micas and other critical minerals such as tantalum and niobium may occur. The target is also supported by strong stream sediment and soil tin geochemistry anomalies and surface rock chip results up to 1.07% Sn generated by an outcropping mineralised gossan over target.
- Carbine Hill East Pb-Zn-Cu-Ag-Au VMS target EL29/2022 ($55,500 grant) One diamond drill hole (220m) planned to target a lead-zinc-copper-silver-gold VMS style deposit within the renowned Mt Read Volcanics which host the nearby Rosebery, Henty, Hellyer, Mt Lyell, Hercules, and Que River mines. The primary target is based on a strong EM anomaly identified from a high resolution airborne Electromagnetic survey flown in 2013 with a modelled Maxwell conductivity plate. The target is also supported by coincident and down slope zinc and lead soil and rock chip anomalies.
- Evenden Pb-Zn-Cu-Ag-Au VMS target EL29/2022 ($63,000 grant) One diamond drill hole (300m) planned to target a lead-zinc-copper-silver-gold VMS style deposit within the Mt Read Volcanics. The primary target is based on a strong EM with a modelled Maxwell conductivity plate and is supported by anomalous zinc, lead and copper rock chip geochemistry results in the surrounding area.
- Southern Extension of Mt Razorback Sn Mineralization EL11/2017 ($70,000 grant) An Exploration Target, in accordance with the JORC Code 2012, of 180,000 to 220,000 tonnes @ 0.8 – 1.0% Sn remaining in the Razorback Mine deposit was defined by Stellar in 2019 based on historical drilling. One diamond drill hole (550m) is planned to test for continuity of mineralisation ~380m below and ~230m south of the remaining Razorback Mine Exploration Target, where the deposit plunges steeply to the south. A secondary target is the potential for the Critical Minerals tungsten, indium, antimony, cobalt, and chromium to occur in association the tin mineralisation.
EDGI is an important initiative of the Tasmanian Government designed to encourage minerals exploration in the state. Stellar has been awarded four out of a total of twelve EDGI Round 8 grants awarded.
Executive Director Gary Fietz commented*: "We are very pleased that the Tasmanian Government has shown its support for co-funding of exploration drilling costs on these four priority exploration targets which we plan to drill over the coming year."*

North Scamander Sn-Base Metals-Critical Minerals Target (EL19/2020)
Introduction
The Scamander district in Northeast Tasmania 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 Scamander EL EL19/2020 including extensive soil and stream sediment sampling and drilling defining areas of anomalous Sn, Zn, Cu, Ag and Pb mineralisation extending to the NW and SE of the historic Great Pyramid Tin Mine within adjacent RL2/2009 held by Tin One Resources Incorporated. The Great Pyramid Tin Mine operated between 1928 and 1936 with 336 tonnes of ore mined at an average recovered grade of 0.88% Sn, implying an average grade of 1.5% Sn1 .
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 (see Figure 1).

The North Scamander tin-base metals-critical minerals target is overlain by an outcropping mineralised gossan, that has generated strong surface stream sediment and soil tin geochemistry anomalies over the prospect and corresponds with a regional scale aeromagnetic anomaly. Rock chip samples from the prospect return grades of up to 1.07% Sn (see Figure 2).
Drilling over the North Scamander target completed in 1981 included 4 shallow percussion and 4 diamond holes 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, Pb, Zn, Cu and Ag values. Previous results include:
NSD2 – 138m @ 0.8% Zn (from 31m), including 1m 0.45% Sn, 6.2% Pb, 7.8% Zn, and 62 g/t Ag.

NSD1 – 13m @ 0.1% Sn, 0.2% Cu, 0.1% Pb, 0.8% Zn and 25 g/t Ag from 163m.

Magnetic Inversion Modelling & Planned Drillhole
Magnetic inversion modelling undertaken by Stellar's geophysical consultants has shown that previous drilling at North Scamander was not deep enough to intersect the core of the regional scale magnetic anomaly which represents a high potential drilling target. The mineral content (Sn, Cu, Pb, Zn, Ag) in previous drillholes increases to the southeast (down dip), and closer to the core of the magnetic anomaly (see Figure 3).
One 750m diamond drillhole (NSD005) is planned targeting;
- a) The core of the intense magnetic anomaly.
- b) The down dip extension to the southeast of the breccia intersections in previous drillholes where, based on previous drilling results, tin, silver, lead, and zinc (+/- indium) are the most likely target minerals.
- c) The hole will also continue past the core of the magnetic anomaly to test the roots of the breccia-hosted mineralisation previously intersected targeting greisen style mineralisation which may occur near the underlying inferred granite margin where tin, lithium micas, tungsten, and other Critical Minerals such as tantalum and niobium may occur.

The proposed hole (NSD005), previous drillholes, magnetic inversion isosurface and the modelled granite surface are shown in cross section in Figure 3.
Stellar was previously awarded a $50,000 EDGI Round 7 grant for drilling at North Scamander which will expire in June 2023 because the hole was not completed within the Round 7 time limit. The previous Round 7 grant is now replaced by this $70,000 EDGI Round 8 grant for co-funding of direct drilling costs.
A drilling rig has been contracted to commence drilling the North Scamander hole in late-May 2023 . The hole is expected to take approximately 2 months to drill and a further 2 months for core processing, sampling, and laboratory analysis to be completed.

Carbine Hill East and Evenden Pb-Zn-Cu-Ag-Au VMS Targets (EL29/2022)
Introduction
The northern part of EL29/2022 in Western Tasmania is located within the Western Mt Read Volcanics, an Early to Middle Cambrian volcaniclastic sequence renowned for hosting world-class Volcanogenic Massive Sulphide (VMS) Pb-Zn-Cu-Ag-Au deposits including; the Rosebery Zn-Pb-Cu-Ag mine, the Henty Au Mine, the Hellyer Zn-Pb-Cu-Ag-Au mine, the historic Hercules Ag-Pb-Zn-Au mine and the historic Que River Zn-Pb-Cu-Ag-Au mine. The Mt Read Volcanics also host the world-class Mount Lyell Cu-Au mine (see Figure 4).

Figure 4 - Location of EL29/2022, other Stellar Resources tenements (red and pink) and Major Mineral Deposits / Mines
A high-resolution helicopter-borne Versatile Time Domain Electromagnetic (VTEM) survey flown by the previous licence owners, Yunnan Tin Australia, in 2013, identified four key electromagnetic (EM) anomalies over the EL29/2022 area including two at Carbine Hill and one at Evenden (see Figure 5).
A significant number of historic mineral occurrences are present within the EL29/2022 area, including the Carbine South historic mine ~250m west of the Carbine Hill East prospect and the Evenden historic mine ~200m southwest of the proposed hole at the Evenden prospect, along with nine other historic occurrences within the immediate Evenden prospect area (see Figure 5).
In 2014 Geotech Ltd, on behalf of Yunnan Tin, completed conductivity and magnetic inversion modelling including creation of Maxwell conductor plate models over these EM anomalies identified from the 2013 VTEM survey. Most VMS deposits in the Mount Read Volcanics have strong EM responses as Cu, Zn and Pb massive sulphide lenses are highly conductive. The Que River and Hellyer deposits were discovered based on EM surveys.
Neither the Carbine Hill nor Evenden EM targets have been drill tested.

Carbine Hill East Modelled Plates, Surface Geochemistry and Planned Drillhole
The Maxwell plate model over the Carbine Hill East prospect is an isolated, sub-horizontal conductor of limited strike extent, interpreted to be hosted in volcaniclastics which may represent a flat lying VMS deposit. A second sub-horizontal Maxwell plate was also modelled at Carbine Hill West however the Carbine Hill East plate has been selected as the initial drill target as it is a much stronger EM anomaly and has a much greater modelled conductivity-thickness.
The Carbine Hill East prospect is also supported by anomalous soil and rock chip Zn and Pb geochemistry results from previous exploration, much of which is offset southwards from the centre of the EM anomaly, down the steep southern slope of Carbine Hill where the targets may have shed downhill (see Lead surface geochemistry plan in Figure 6).

Figure 6 - 2013 VTEM Ch45 anomalies with historic rock chip and soil results for Lead, historic mineral occurrences and EL29/2022 Drill Targets
One 220m helicopter supported diamond drillhole (CHE001) is proposed to be drilled at the Carbine Hill East targeting a Pb-Zn-Cu-Ag-Au VMS deposit based on a strong modelled EM Maxwell conductivity plate (T1) and coincident and down slope Zn and Pb soil and rock chip anomalies (see Figure 7).
A secondary target is vein and/or fault related Pb-Zn-Ag-Cu-Sn-Sb mineralisation associated with hydrothermal fluids that accompanied Devonian granite intrusions which are common in the area.
The Carbine East hole is expected to be drilled in early-2024, after; (a) MRT complete the formal process of granting EL29/2022 which commenced in December 2022, (b) follow up surface geochemistry sampling, (c) drilling access planning, and (d) permitting is completed.
A $55,500 EDGI Round Eight grant has been awarded for the Carbine East hole, comprising of $35,500 cofunding of direct drilling costs and $20,000 towards helicopter support costs.

Evenden Modelled Plates and Planned Drillhole
The Maxwell plate model over the Evenden prospect targeted by the proposed hole is the central of four subhorizontal plates modelled over the Evenden prospect by Geotech Ltd with a substantial amount of volcaniclastics interpreted below the conductors and a major northwest trending fault dividing the conductors into two groups. The conductors also appear to be located next to an intrusive with strong magnetic responses. The four modelled plates at the Evenden prospect display an overall dome like structure, intersected by faults, which may represent a VMS mound structure formed by hydrothermal convection on the sea floor.
The Evenden prospect is also supported by anomalous Zn, Pb and Cu rock chip geochemistry results from previous exploration in the area surrounding (see Lead surface geochemistry plan in Figure 8).
One 300m helicopter supported diamond drillhole (EVN001) is proposed to be drilled at Evenden targeting a Pb-Zn-Cu-Ag-Au VMS deposit based on a strong modelled EM Maxwell conductivity plate (T3) and anomalous Zn and Pb rock chip geochemistry results in the area surrounding the Evenden prospect (see Figure 9).
A secondary target is vein and/or fault related Pb-Zn-Ag-Cu-Sn-Sb mineralisation associated with hydrothermal fluids that accompanied Devonian granite intrusions which are common in the area.
The Evenden hole is expected to be drilled in early-2024, after; (a) MRT complete the formal process of granting EL29/2022 which commenced in December 2022, (b) follow up surface geochemistry sampling, (c) drilling access planning, and (d) permitting is completed.
A $63,000 EDGI Round Eight grant has been awarded for the Carbine East hole, comprising of $43,000 cofunding of direct drilling costs and $20,000 towards helicopter support costs.

Southern Extension of Mt Razorback Sn Mineralization (EL11/2017)
Introduction
Tin mineralization at the historic Razorback Mine occurs as cassiterite associated with pyrrhotite, pyrite and arsenopyrite within a broader alteration zone of talc/carbonate/silica rock. The mineralised alteration zone is from 3m to 30m thick, strikes NNW, is near vertically dipping and lies within and parallel to the Razorback Fault which juxtaposes serpentinites and conglomerates/shales of Cambrian Dundas Group sediments.
The Razorback Open Pit Mine was operated by Minops Ltd from 1975 to 1978 with tin recovered from a simple gravity plant and tailings placed in a nearby storage facility. The mining operation ceased after extracting 180,000t of ore grading 0.6% Sn and producing 53t of tin in concentrate. Mill recoveries averaged only 40%.
In 2019, Stellar defined an Exploration Target in accordance with the JORC Code 2012 of 180,000 to 220,000 tonnes @ 0.8 – 1.0% Sn remaining in the Razorback Mine deposit based on historical drilling. The Exploration Target extends to a depth of ~100m below the pit floor2 .
Planned Drillhole
One 550m diamond drillhole is proposed to test for continuity of mineralisation ~380m below and ~230m south of the remaining Razorback Mine Exploration Target where the deposit plunges steeply to the south (see Figure 10).
The primary objective of the planned hole is to identify additional tin mineralisation a significant distance down plunge of the remaining Exploration Target which, along with further drilling, may support the definition of a much larger remaining tin resource with the potential to support the economic development of an underground mine at Razorback. The hole will also test a proposed geological structural model, that higher grade zones may occur in semi-contiguous down plunge dilatational zones within the Razorback deposit.
The secondary objective of the planned hole is to explore for Critical Minerals in addition to tin. There is the potential for the Critical Minerals tungsten, indium, antimony, cobalt, and chromium to occur in association with this style of tin mineralisation. None of these Critical Minerals have ever been analysed for in previous drilling at Razorback.
The timing of drilling the Razorback hole will be determined following Stellar's application for an Extension of Term of EL11/2017 is approved, which is currently being processed.
A $70,000 EDGI Round Eight grant has been awarded for the Razorback hole.
