The Directors of Stellar Resources Limited (ASX: SRZ, “Stellar” or the “Company”) are pleased to advise that the Company has added to its portfolio of Tasmanian tin properties with the recent grant of Mount Razorback EL11/2017. The EL contains the historical Razorback and Grand Prize tin mines and a tailings dam. Between 1975 and 1978, the Razorback mine produced 153t of tin in concentrate valued at $3.8m at today’s A$ tin price. This property has a number of attributes that make it a particularly attractive bolt-on for the Heemskirk Tin project.
-
Close proximity to Zeehan (10km on existing roads) and the Renison tin mine (8km to the north)
-
Potential to recover cassiterite tin from the tailings dam
-
Potential to define a mineral resource below the Razorback open pit
-
Exploration potential along a 3km fault structure between the Razorback and Grand Prize mines.
Managing Director Peter Blight said “Adding the Mount Razorback EL to the Company’s portfolio of Tasmanian tin assets is a great way to start the new year. This is the third significant tin asset in a portfolio that already includes JORC resources at St Dizier and Heemskirk.”
“The synergy Mount Razorback offers Heemskirk Tin and the advanced nature of its tin prospects make it a compelling addition” he added.

Location
The Mount Razorback EL is located 10km to the east of Zeehan (see Figure 1). There is an unsealed road network within the EL that allows easy access to historical mines and the main exploration targets. Any economic tin mineralisation discovered within the EL could be easily transported to a proposed processing facility at Zeehan or any other processing facilities in the area.

Exploration Potential and Work Program
Stellar plans to focus on the Razorback mine and associated targets with three opportunities identified to date.
-
1) The economic recovery of tin from tailings . Sampling and metallurgical testing of tailings should establish whether modern processing technology can improve on historical recovery to produce a saleable product. Initial sampling and tailings characterisation is to be completed in March quarter 2018.
-
2) Identification of a resource below the open pit . Diamond drilling by previous title holders both before and after Minops mining activity has shown that a resource exists below and down-plunge of the open pit. During March quarter 2018 , Stellar plans to create a 3D model of historical drilling in order to establish a JORC 2012 compliant mineral resource and to identify drilling targets.
In addition, the availability of an open pit will allow sampling across the pit floor to establish the distribution of mineralisation and access for the extraction of a bulk sample for metallurgical testing. Any improvement in recovery from the tailings test work should also have positive implications for the resource.
- 3) Along-strike exploration. The Razorback Fault extends for more than 3km to the north and south of the mine (see Figure 2). It provides an attractive geological setting for repetition of the Razorback mineralisation. In addition, surveys by previous explorers show elevated tin in soil in the vicinity of the fault. Historical diamond drilling to the north and south of the Razorback mine is sparse providing an opportunity for further exploration.

Geology
Shales, greywacke and conglomerates of the Cambrian Dundas Group comprise the dominant rock group in the area (see Figure 2). It is likely that the sediments were intruded by a sill of ultramafic pyroxenite which was subsequently serpentinised. Deformation during the Devonian, led to folding of the sediments and the development of northwest trending faults that in the Mt Razorback area juxtaposed serpentinite against conglomerates and shales. The faults were also conduits of hydrothermal fluids that altered the wall rocks and in places decomposed serpentinite to talccarbonate-silica rock.
Figure 2: Simplified Geological Plan EL11/2017
==> picture [264 x 383] intentionally omitted <==
Mineralisation
At the Razorback mine, the talc-carbonate-silica alteration zone strikes over 200m along the fault and varies in thickness from 3m to 30m. It contains tin in the form of cassiterite along with pyrrhotite, pyrite and arsenopyrite. At Grand Prize, the alteration is less developed, possibly due to the absence of serpentinite and mineralisation occurs in sulphide veins within the Grand Prize Fault.
The tin deposits at Grand Prize and Razorback are often compared to that at Renison. The reason for the comparison is that all deposits are associated with northwest trending structures (as are the Heemskirk deposits), have similar mineralogy and lie in close proximity to the Pine Hill quartz porphyry, long viewed as the source of the tin bearing hydrothermal fluids at Renison.

History of Mining
In 1909, tin was discovered at Grand Prize and Razorback by tracing alluvial tin to its source rock. Initial mining at both deposits involved shaft sinking, driving and hand sorting to produce small volumes of concentrate. Between 1909 and 1960, several syndicates operated the Grand Prize mine.
At Razorback a processing plant was built in 1918 and was operated sporadically by several different owners until the 1960s. In 1974, Minops Pty Ltd completed a feasibility study on Razorback and subsequently developed an open pit mine and concentrator (see Figure 3). According to Annual Reports produced by Mineral Resources Tasmania, the mine operated from 1975 to 1978 and produced 100,352t of ore from which 153t of tin in concentrate were recovered.

Heemskirk Tin Project
Stellar Resources Limited is a tin exploration and development company that is focused on developing its flagship Heemskirk Tin Project in western Tasmania.
The project has two significant competitive advantages. First, Heemskirk has a JORC 2012 compliant Mineral Resource of 6.4mt @ 1.13% Sn which makes it the highest grade undeveloped tin project of significance listed on the ASX. Second it has an excellent location within the historic west coast mining district of Tasmania (see Figure 4).
Access to existing infrastructure including power, sealed roads and water is a significant advantage over more remote tin projects. In addition, the project is located next to the mining town of Zeehan which provides a supportive community, access to skilled miners and accommodation. The service industry, established to support existing long-term mines in the district, also provides an opportunity for access to competitive suppliers.

In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or sampling types (e.g. submarine nodules) may warrant disclosure of detailed information. |
• EL11/2017 contains two historical tin mines Razorback and Grand Prize. Early, small-scale and intermittent production from both mines began in 1909.

Minops Pty Ltd mined Razorback from 1975 to 1978. After the mine closed, CRA limited explored around the mine from 1978 to 1980. |
| Geology | • Deposit type, geological setting and style of mineralization. |
• Tin mineralization at the Grand Prize mine is related to small, discontinuous and thin fissure lodes within the Grand Prize Fault. • Tin mineralization at Razorback occurs as cassiterite associated with pyrrhotite, pyrite and arsenopyrite within a broader alteration zone of talc/carbonate/silica rock. The alteration zone is from 3m to 30m thick and 200m in strike length. It lies within and parallel to the Razorback Fault which juxtaposes serpentinites and conglomerates/shales of Cambrian Dundas Group sediments. |

• In reporting of Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cutoff grades are usually material and should be stated. • Where aggregate intercepts include short lengths of high grade results and longer lengths of low grade results, the procedure used for aggregation should be stated and some examples of such aggregations should be shown in detail • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• No exploration results are reported in this release. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. down hole length, true width not known) |
• No drill results reported in this release. |
