Proposed Option Entitlement Issue to shareholders
Tando Resources (“ Tando ” or “ the Company ”) is pleased to advise on the current status of its exploration projects in the Pilbara region of Western Australia prior to its listing today on the ASX.
Quartz Bore – Drilling to Commence
In preparation for its maiden drill programme the Company will commence a heritage survey at the Quartz Bore Project (E47/3352) with the Ngarluma Aboriginal Corporation, representatives of the Native Title Claimant Group.
It is anticipated that drilling will commence later in November. An Exploration Programme of Works has already been approved by the Department of Mines Industry, Regulation and Safety.
Drilling aims to verify historical results from the Quartz Bore Project including:
-
15m @ 5.92% Zn, 0.80% Cu and 1.45% Pb (BBD009)
oincluding 6m @ 7.34% Zn -
15m @ 5.11% Zn, 0.12% Cu and 1.89% Pb (BBRC007)
oincluding 5m @ 12.5% Zn
==> picture [596 x 106] intentionally omitted <==
-
3m @ 15.5% Zn, 0.76% Cu and 4.90% Pb (BBD003)
-
7.6m @ 4.86% Zn, 2.13% Cu and 1.56% Pb (BBD002)
oincluding 2m @ 13.71% Zn -
10m @ 4.45% Zn, 0.22% Cu and 2.54% Pb (BBRC005)
oincluding 2m @ 9.74% Zn
All drillhole results are listed in Appendix 1 and shown on Figure 1.
Downhole geophysical surveys will be completed on all holes with the aim of detecting extensions to mineralisation via the DHMMR and DHEM methods. These methods have been successfully employed by the Company’s consultants Southern Geoscience at the adjacent Salt Creek Deposit, owned by Venturex Resources (refer VXR’s ASX Announcement 31 May 2017).

Mt Sydney – Airborne EM survey planned for November
The Mt Sydney Project (E47/4939) lies immediately south of the Braeside Project where drilling will commence in late November by Rumble Resources Limited (ASX.RTR, “ Rumble ”). The Braeside Project is centred on the historical Ragged Hills Mining centre, at which mineralisation is now interpreted to be associated with sub-volcanic rhyolite porphyries. The deposit model at Braeside highlights regional scale NWSE structures as a key target for Volcanogenic Massive Sulphide ( VMS ) mineralisation.
On 4 September 2017 Rumble announced the results of an airborne EM survey using the VTEMmax system which detected a substantial number of early- and late-time conductors associated with the structures mentioned above. On 16 October 2017 Rumble announced the presence of high grade zinc, lead and copper results from grab sampling over the conductors detected in the VTEMmax survey and other geochemical anomalies within their tenements. Significantly Rumble have not yet announced the presence of “false positives” such as graphitic shales and are currently completing a ground EM survey at the Braeside Project with drilling planned for later in November 2017
The same structures and lithologies which host mineralisation at the Braeside Project extend into the Company’s Mt Sydney Project. As a result Tando has engaged Geotech Airborne to fly a VTEMmax survey over the Mt Sydney Project. This survey is anticipated to commence in 2 - 3 weeks with results likely to be received in early December following which field inspection and ground surveys will be planned. This systematic exploration approach resembles the exploration derisking applied on Rumbles Braeside Project.
Mt Vernon – Review of historical exploration underway following tenement grant,
The tenement which comprises the Mt Vernon Project (E52/3560) was granted on 24 August 2017. Review of historical exploration is already underway including a number of historical geochemical and geophysical surveys including drainage, soil and rock sampling; radiometric, gravity and IP surveys; and RC and diamond drilling.
Previous exploration in the area of the Mt Vernon Project was completed by Westfield Minerals, Aberfoyle Resources, BHP Minerals, CRA Exploration, Rio Tinto Exploration, Geotech International, Independence Group and Pioneer Resources.
Historical explorers have identified targets related to both sediment-hosted zinc-lead and structurally controlled copper mineralisation in the area of the Mt Vernon tenement, in similar settings to the Abra Base Metals Deposit (owned by Galena Mining (ASX.G1A)) and Newman Base Metals Project (owned by Marindi Metals (ASX.MZN)).
Tando will complete an initial review aimed at confirming the data which supports these targets and then design work programmes to test the most prospective targets.

Prospectivity for Conglomerate-hosted Gold and other Pilbara gold potential
Recent activity in the Pilbara region has focussed on conglomerate-hosted gold mineralisation as well as other gold mineralisation. While the focus of Tando Resources is on its advanced and prospective zinc targets it is worth noting that the Company’s tenements are within, or adjacent, to areas of interest for gold mineralisation:
-
The Mt Sydney tenement is underlain by the base of the Fortescue Group, including the Hardey Formation within which a number of conglomerate units have been mapped
-
The Quartz Bore Project is adjacent to Venturex’s Loudens Patch Prospect and proximate to recent “nugget patch” discoveries by De Grey Mining and DGO Gold (refer ASX.VXR Announcement 18 October 2017, ASX.DEG ASX Announcements 26 September 2017 & 30 October 2017 and ASX.DGO Announcement 25 October 2017).
Identification of prospective lithologies on the Company’s tenements, or of potential gold occurrences, is complicated by the present of recent cover. The Company plans to investigate a number of areas of interest on its tenure as fieldwork commences in each area.
In addition the Company plans to evaluate and take advantage of any new opportunities that it identifies in the region.

APPENDIX 2.
The following Tables are provided to ensure compliance with the JORC Code (2012 Edition) requirements for the reporting of the Exploration Results at the Quartz Bore Project.
Section 1: Sampling Techniques and Data (Criteria in this section applies to all succeeding sections)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. |
Several generations of drilling have been undertaken on the Quartz Bore Project since the 1970’s. The drilling results detailed in this report were from drilling undertaken by Straits Resources Ltd (ASX:SRL) during 2005-2007 and Venturex Resources Limited (ASX:VXR) during 2010-2012. All results have been previously reported under JORC 2004 reporting standards to the Australian Stock Exchange. Main exploration activities included a combination of surface geochemical sampling and several drilling methods. Conventional Diamond Drilling (DD), Reverse Circulation (RC), Aircore (AC) and Auger were used to the test the Quartz Bore Project. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Core sample intervals vary depending on geological contacts and are generally between 0.3m and 4.0m, with the most often sample interval being 1.0m. Prior to cutting, the core was marked up by a geologist, orienting the core where possible to ensure the relative orientation of consecutive pieces of core. All core wasphotographed for reference. |
|
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
All aspects of the determination of mineralisation are described in this table. The core sampling method and the RC sampling method is considered appropriate for the VMS mineralisation. All of the drill samples were sent to a commercial laboratory for crushing, pulverising and chemical analysis by industry standard practises. |
|
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic etc) and details (e.g. core diameter, triple of standard tube, depth of diamond tails, face-sampling bit or other type, whether core is orientated and if so, by what method, etc). |
Drilling methods included Diamond Drilling (DD), Reverse Circulation (RC), Rotary Air Blast (RAB) and Auger. Diamond drilling used HQ and NQ2 core sizes. Coring was from surface using HQ. Core was changed to NQ2 when ground conditions were competent. All NQ2 core was orientated. All diamond core was stored in industry standard core trays labelled with the drill hole ID and core interval. RC drilling used an industry standard 5.5 inch face sampling hammer. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
All operators recorded diamond drill core recovery as a percentage of measured recovered cores versus drilled distance. Recoveries were generally high except for cavity zones in the oxide zone. RC samples were collected to industry standards of the day. The locations of intervals of damp or wet samples and/or low recovery were recorded at the drill site and entered into the database. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
RC drilling - the cyclone and splitter were routinely inspected and cleaned during the drilling, ensuring no excessive material build-up. Care was taken to ensure the split samples were of a consistent volume. Diamond drilling - coring was from surface using HQ and only changed to NQ2 when ground conditions were competent. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
There is no known or reported relationship between sample recovery and grade with the RC drilling. With the Diamond Drilling, recoveries were generally high except for cavity zones in the oxide zone. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
The RC drill holes were geologically logged at 1m intervals for the total length of the hole using the company standard logging legend. The logs were recorded on company standard paper logging sheets and entered into the company database. Diamond drill core was geologically logged for the total length of the hole using a graphic logging method. All core was photographed and images were stored in the company database. Logging routinely recorded lithology, mineralogy, alteration, veining, structure, mineralisation and weathering. Logs were coded using the company geological coding legend and entered into the company database. Logging is appropriate and sufficiently detailed to support Mineral Resource estimates. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
Logging of chips and diamond core is both qualitative (eg. colour) and quantitative (eg. minerals percentages). All core was photographed and images were stored in the company database. Various historical reports contain petrography reports. |
|
| The total length and percentage of the relevant intersections logged. |
100% of all core and RC samples which included all mineralised intervals was logged. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
Sampling for all of the diamond core was undertaken on split core, halved via a core saw. Where duplicate samples were required the core was quartered with two duplicate quarter core samples sent for assay and the remaining half-core returned to the tray as a record. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
AllRCdrill holes and pre-collars were sampled from the rig via 1m splits to calico bags, with a target weight of between 2kg to 4kg. The bulk sample reject was collected in a UV-destabilised green plastic bag and kept at the drill site. All sample bags were sampled by |

| spear on a 4m compositing interval. Sample intervals which returned significant anomalies in base metals (>0.2% Cu, >0.2% Zn, >0.2% Pb) were then resampled via collection of the 1m splits from the drill rig. Where sample quality was insufficient, the bulk sample was dry split through a 2- tier riffle splitter and a split sample was collected. |
||
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
The sampling techniques for both diamond drilling and RC drilling are of consistent quality and appropriate. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
Detailed QAQC procedures and data for the historical drilling is not available. Field duplicates were collected as quartered diamond core, as 1m spear samples, or as 4m composite samples identical as much as practically possible to the original sample. |
|
| Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second- half sampling. |
QAQC has been reported to have been routinely conducted throughout historical drilling and geochemical sampling, however methodologies are not documented. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
The material and sample sizes are considered appropriate given the volcanic massive sulphide style of mineralisation beingtargeted. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
The analytic methods for the programs with significant results which have been tabled in Appendix 1 are outlined below. Theaircoresamples were collected were for litho- geochemical purposes both at the end of the hole, and as 3 metre composite samples. Down hole samples were taken and analysed by ALS in Perth. Samples were analysed for Au by fire assay (Method AA25) using a nominal 30 gram sample weight. The samples were also digested with HF-HNO3-HCLO4acid, leached in HCl, and analysed for ICP-AES method MEICP61. Via this method assays for the following elements were recorded: Au, Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W and Zn. Any samples with a Cu value exceed 0.3% (3000ppm) were also analysed for Cu sequentially, determining the amount of Cu dissolvable in H2SO4, dissolvable in cyanide, and the residual amount of Cu. AllRCdrillholes and pre-collars were sampled from the rig via 1m splits to calico bags, with a target weight of between 2kg to 4kg. The bulk sample reject was collected in a UV-destabilised green plastic bag and kept at the drill site. All sample bags were sampled by spear on a 4m compositing interval and sent for indicative geochemistry to ALS-Chemex Laboratories, Perth, for analysis via method MEICP61 (see analysis details above in auger section). Sample intervals which returned significant anomalies in base metals (>0.2% Cu, >0.2% Zn, >0.2% Pb) were then resampled via collection of the 1m splits from the drill rig. Where sample quality was insufficient, the bulk sample was dry split through a 2- tier riffle splitter and a split sample was collected. Samples were sorted,dried,coarse crushed and |

| pulverised to p80-5um. Base metals and trace elements were analysed by method MEICP61 4 acid-digest and analysed by ICP-AES. The samples were analysed for Au by fire assay with an AAS (Atomic Absorption Spectrometer) finish, using a nominal 30 gram sample weight. The following multi-elements were digested in Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sr, Ti, V, W & Zn. Where any samples exceeded a Cu value 0.3% (3000ppm) another sample was taken from the sample pulp and analysed for Cu sequentially, determining the amount of Cu dissolvable in H2SO4, dissolvable in cyanide, and the residual amount of Cu. Sampling for all of thediamond corewas undertaken on split core, halved via a core saw. Where duplicate samples were required the core was quartered with two duplicate quarter core samples sent for assay and the remaining half-core returned to the tray as a record. The samples were sent to ALS for preparation and analysis. All samples were analysed for Au by fire assay (method AA25) and AAS (Atomic Absorption Spectroscopy), using a nominal 30 gram sample weight. The following multi-elements were digested by 4-acid digest with ICP-AES finish; Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sr, Ti, V, W, and Zn. Where any samples exceeded a Cu value 0.3% (3000ppm) another sample was taken from the sample pulp and analysed for Cu sequentially, determining the amount of Cu dissolvable in H2SO4, dissolvable in cyanide, and the residual amount of Cu. |
||
| For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |
Hand held assay devices have not been reported. | |
| Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
Quality control exercised upon laboratory analyses included the insertion of standards and the collection of field duplicates. Field duplicates were collected as quartered diamond core, as 1m spear samples, or as 4m composite samples identical as much as practically possible to the original sample. All standards and blanks were inserted blind into the sample stream sent to the laboratory and assessed for variance from expected norms via statistical analysis. Where QAQC was insufficient, the batch was re-analysed. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
No verification of sampling and assaying has been undertaken by Tando for the historical drilling. |
| The use of twinned holes. | No specific twinned holes have been drilled. | |
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Detailed procedures for drilling, sampling and geological logging are not comprehensively including in Open File reports, although summaries of the processes employed are provided in various drilling reports. Digital data has been collated from digital data submitted to the Department of Mines and Petroleum. |

| Validation occurs during the data merge through the database software and with visual validation in GIS software packages. |
||
| Discuss any adjustment to assay data. | The digital data shows no indication of assay adjustment being performed. |
|
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
Rock samples were located in the field with survey control via handheld Global Positioning System (GPS), with an assumed accuracy (dither factor) of ±5m accuracy on easting and northing and ±10m accuracy on RL, Location data for aircore, RC and diamond drillhole data included in Annexure A was initially recorded by handheld GPS (±5m accuracy on easting and northing and (±10m accuracy on RL). Subsequent to drilling, RC and diamond drill collars were surveyed via Differential Global Positioning System (DGPS), with accuracy of ±0.1 meters on easting, northing and RL. Drillhole deviation for diamond drilling was measured via in-rod surveys during drilling, This was conducted using Eastman camera surveys. Interference from the drill rods cannot be ruled with the RC drillholes, so these results are only considered indicative, however a stainless steel started rod was used to increase confidence in the results. WBRC028 through WBRC031 were drilled subsequent to the loss of the stainless steel equipment, and as such down-hole deviation is unknown. This is considered acceptable given the results returned from these holes. Diamond drilling received down hole surveys every 30 metres were possible, via in-rod shots, which are considered reasonably reliable. Holes that struck mineralisation had 50mm PVC pipe installed, keeping the hole open and allowing a gyro survey to be undertaken. A selection of these holes were surveyed with a north-seeking gyroscopic survey tool by ABMI Solutions Pty Ltd to give a true down-hole survey free from magnetic interference. The accuracy of this tool is warranted to ±0.5° of dip and azimuth. Deviation in the holes drilled during the 2007-2009 reporting periods were generally low. The majority of the holes surveyed with the gyroscopic tool confirmed the previous in-rod surveys, and thereby the Eastman results were considered accurate. |
| Specification of the grid system used. | The grid system for the Quartz Bore Project is Map Grid of Australia GDA 94, Zone 50. |
|
| Quality and adequacy of topographic control. | The RL of drill collars (RC and diamond) was measured by DGPS survey to an accuracy of ±0.1 meters which gives a satisfactory control over the topography. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | The spacing and location of the majority of the drilling at the Quartz Bore Project is, by the nature of early exploration variable. Drilling to date over the Balla Balla Prospect is on approximately 50m - 100m centres east- west and 25m -100m centres north-south over the |

| mineralised body. | ||
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
Data spacing is deemed sufficient to establish geological and grade continuity to establish a mineral resource estimate but a mineral resource has not been estimated. |
|
| Whether sample compositing has been applied. | No sample compositing has been applied. | |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. |
The majority of the drilling at Quartz Bore is inclined to the north-west which is considered appropriate given the regional and local geological fabric and structures. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
To date, orientation of the mineralised domain has been favourable for perpendicular drilling and sample widths are not considered to have added a significant sampling bias. |
|
| Sample security | The measures taken to ensure sample security. | Samples were store at the secure Whim Creek yard. Samples were collected from site by a transport company and delivered to the assay laboratory in Perth. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
No independent audits have been undertaken. |
Section 2: Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. |
The Quartz Bore Project comprises a single granted Exploration Licence, namely E47/3352 covering a land area of 15 km2. Tando has acquired 100% of the tenement from the current holder, VMS Resources Ltd, following the listing of the Company. The tenement is within land where native title has been determined. The traditional owners of the land are the Ngarluma People. A Heritage Agreement has been signed with the Ngarluma Aboriginal Corporation to manage access. |
| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
The tenement is in good standing. | |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
The Project has previously been explored for volcanic massive sulphide deposits by a number of companies. Work has ranged from early stage soil sampling to auger and diamond drilling. Work reported in the IGR is documented within this Table. |

Massive sulphide and stringer sulphide mineralisation has been deposited at the top of the Cistern Formation which comprises a thick sequence of volcanogenic siltstone, sandstone and conglomerate with minor shale units. |
|
| Drill hole Information | A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. |
All hole collar locations, depths, azimuths and dips are provided within this announcement (Appendix 1) for drilling completed by Straits and Venturex. |
| If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Not applicable. | |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
Reported intersections are downhole, length- weighted averages that were calculated using a nominal ≥1.0% Cu lower cut-off, ≥1.0% Pb lower cut-off or ≥1.0% Zn lower cut-off; 1m minimum reported length and up to 3m of internal waste. Geochemical sampling results presented are single point data. |
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
No top cuts have been considered in reporting of grade results, nor was it deemed necessary for the reporting of significant intersections. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent values are currently being used for reporting exploration results. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
All intersections are reported as downhole lengths. Drillholes were predominantly drilled perpendicular to the interpreted strike of the geological terrain so that downhole lengths approximate true widths as close as possible. Additional drill holes are required to confirm the relationship between downhole lengths and true widths. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Refer to Figures in body of announcement and in the Prospectus released to the ASX on 1 November 2017. |
| Balanced reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleadingreportingof Exploration |
All representative results have been reported. |
