Update on Tartana Resources Limited
SciDev Ltd (ASX: SDV , SciDev or the Company ) is pleased to advise that Tartana Resources Limited has released excellent Exploration Targets for the Tartana Copper/Zinc Project (Queensland) and an Indicated Resource for the Zeehan Project (Tasmania).
The full text of Tartana’s announcement is attached. SciDev understands that Tartana Resources Limited is moving towards commencing its ASX IPO capital raising process in the near future.
SciDev currently owns 19.9% of Tartana Resources Limited and will hold a significant position in the Company moving forward. This will give SciDev and its shareholders exposure to the exciting upside at all Tartana’s project areas, particularly the Tartana and Zeehan Projects.
Further details will be provided as they come to hand.

Quantification of Exploration Targets on the Tartana Copper/Zinc Project and announcement of an Indicated Resource for the Zeehan Zinc Slag Project
Tartana Resources Limited (" Tartana ") is pleased to announce that it has commissioned the services SRK Consulting (Australasia) Pty Limited (“ SRK ”) to provide JORC 2012 compliant Open Pit Exploration Targets for the Queen Grade Zinc Project, the Copper Sulphide Project below the existing open pit and the Valentino Copper Project. These three projects are on granted Mining Leases which are located approximately 40 km northwest of Chillagoe, north Queensland.
Encouragingly, while the Exploration Targets are classified as conceptual in nature and which may not be substantiated by further drilling, these Exploration Targets have been supported by historical drilling and represent separate material zinc and copper targets reflecting both zinc skarn and porphyry copper systems.

The contained zinc and copper in the Exploration Targets is for open pit mining only and do not reflect deeper targets associated with each project that may be amenable to underground mining methods. Details of these Exploration Targets are outlined in the following sections.
The mining leases also include a heap leach - solvent extraction - crystallisation plant which has been on care and maintenance since 2014. This plant can produce copper sulphate for sale into the domestic market and Tartana is

investigating the opportunity of restarting production. However, the Exploration Targets stated below do not refer to oxide copper mineralisation which would be suitable for leaching and this will be the subject of a separate drilling campaign.
In addition, Tartana has commissioned Bluespoint Mining Services Pty Ltd (“ BMS ”) to estimate an Indicated Resource Statement which is JORC 2012 compliant for the Zeehan Zinc Slag Project in consultation with SRK. This is the first time that these zinc bearing stockpiles have been classified under JORC classification.

The Indicated Mineral Resource tonnage is higher than previous non JORC reported estimates by previous owners and reflects recent work on further quantifying the density and volume of the stock piles and this includes a recent 7 hole air core drilling programme. In addition, the average grade of indium from samples from the recent 7 hole air core programme was 52 ppm in the north stockpile and 28 ppm in the south stockpile but there are insufficient data to categorise these average grades as indicative of the entire resource as indium was not assayed in samples from an earlier drilling programme.
On reviewing the results, Chairman Dr Steve Bartrop commented that this work is a significant achievement in allowing investors to appreciate the potential of our projects. The Tartana Project has been held in private hands for over 20 years and while it successfully produced copper sulphate for many years, the opportunities existing within its mining lease have not been quantified before. In addition, the higher level of confidence in the Zeehan zinc slag resource will assist the Company to be able to commercialise this resource.
Tartana Copper/Zinc Project
The Tartana Copper/Zinc Project consists of four granted mining leases located approximately 40 km northwest of Chillagoe, north Queensland (Figure 1). The location of the Queen Grade Zinc Project, the Tartana Copper Mine and the Valentino Project within the mining leases is also indicated on Figure 1 along with site infrastructure.

Queen Grade Exploration Target
The Queen Grade Zinc Project represents outcropping proximal zinc skarn mineralisation which is similar to neighbouring King Vol mineralisation and other skarn mineralisation in the Chillagoe Belt. Historical drilling has involved a number of RC programmes since the early 1990’s and more recently, selected diamond drilling for a total of 12 holes.

Figure 2. Historical drilling at Queen Grade
SRK reports that the drilling and surface alteration expression have been used to estimate a strike (200 to 400 m), width (thickness 10 m to 25 m) and depth below oxide (50 m to 100 m) for a deposit that may be recovered by open pit mining methods. This density (2.7 to 2.9 t/m[3] range) has been based on mineralisation observed in drill core.
In addition it notes that while the grades at the nearby King Vol deposit are high enough to support an underground mine, the grade and depth at Queen Grade have yet to be sufficiently tested to support an underground Exploration Target.
The Queen Grade Exploration Target considered accessible to surface (open pit) mining is shown in Table 4.

Deeper Copper Sulphide and Valentino Exploration Targets
The Tartana copper mine operated a heap leach - solvent extraction -– crystallisation plant to produce copper sulphate until 2014 when it was placed on care and maintenance. Duing its operations it mined oxide copper ore in a shallow open pit which was crushed and placed on the heaps.
The Company proposes to explore below this open pit mine as part of the Deeper Copper Sulphide Project as well as the Valentino Project. These targets are identified on ground based Induced Polarisation (IP) and Resistivity Surveys as well as Geochemistry Surveys.
The IP Survey identifies a significant target (the green in Figure 3 as it also coincides with mineralisation which has been drilled below the open pit (red zone).

Figure 5. The Deeper Sulphide (Tartana Target) and the Valentino Target and copper in soil geochemistry.
The Tartana Deeper Sulphide target is in both the weathering transition zone (supergene zone) and primary rock beneath the previously mined open pit oxide copper resource (now partially backfilled). The final survey for the existing pit has yet to be located, consequently, there is some uncertainty about the location of the top of the deposit and which will be defined with future drilling programmes.
SRK note that the sulphide resource has been intersected in a number of deeper holes which indicates it dips steeply south-west. The strike (est. 500 m to 600 m), width (thickness 40 m to 60 m) and dip extends below the oxide to a depth (est. 140 m to 200 m) that it believes may reasonably be mineable from an open pit.
The density range (2.6 to 2.8 t/m[3] ) has been based on density determinations from Tartana core and typical densities for the rock types present at the Tartana Project. A grade range of 0.6% to 0.8% Cu has been used to reflect the average grades from drilling assays that intersected the sulphide zone.
SRK has based the Valentino conceptual Exploration Target on a surface copper in soil anomaly which covers an area that is smaller than the anomaly at the Tartana Copper Mine (due to poor surface expression) and a number of mineralised intersections from shallow drilling. The Valentino geochemical target (identified from soil and shallow drilling) coincides with an NNW striking IP resistivity high that has a strike of 700 m to 800 m. The target is poorly drilled and highly conceptual with wide spaced drilling although drill holes TRDH 15A, TRDH 16, TRDH 18 and RB 11 all intersected mineralisation that coincides with the IP anomaly. An additional zone of mineralisation in the southern part of ML4819 also coincides with a smaller IP resistivity high and may be shallowly dipping.
SRK note that a deeper target for possible underground mining has not been considered at this stage due to a lack of data to determine continuity at higher grade. The depth to the base of oxide is approximately 30 to 40 m from surface. The depth of the sulphide below oxide used for the Exploration Target is 40 m, representing up to 240 m below surface where the deposit is assumed to be 60 m thick.
