COMPELLING TARGETS DEFINED BY VTEM SURVEY AT MT SYDNEY
-
Substantial number of near surface EM anomalies detected in airborne survey at 100% owned Mt Sydney Project.
-
Clear analogy with adjacent Braeside Project (owned by Rumble Resources) where the maiden drilling programme included a high grade zinc discovery.
-
Key regional scale structures extend directly from Braeside Project into the Mt Sydney Project. EM anomalies are clustered along these structures.
-
In addition a compelling large scale target defined by broad coincident EM and magnetic anomaly, interpreted to represent a deeper intrusive body.
-
Drill targets to be delineated by detailed geological mapping and geochemical surveys during 2018 field season.
Tando Resources (“ Tando ” or “ the Company ”) is pleased to advise that it has received preliminary data from the VTEMmax survey carried out in December 2017 at its 100% owned Mt Sydney Project, in the Pilbara region of Western Australia. The Mt Sydney Project is located adjacent to, and along strike from, Rumble Resources (ASX.RTR, “ Rumble ”) Braeside Project.
The VTEMmax survey comprised approximately 1,300 line kilometres flown in an east-west orientation by Geotech Australia, at a 400m line spacing. Initial processing of the data has detected a substantial number of near surface EM anomalies aligned along major regional structures within the Mt Sydney Project (Figure 1 and 2). These structures extend directly from the Braeside Project and represent the key targets for base metal mineralisation. EM anomalies lying on these structures are therefore highly prospective .
Rumble recently announced results from its maiden drilling programme including a high grade zinc discovery at the Braeside Project (refer ASX.RTR Announcement 16 January 2018). Mineralised zinc-lead intersections reported include 4m at 9.64%Zn + 0.41%Pb from 32m, 2m at 3.08% Zn + 2.98% Pb from 60m and 3m at 2.19%Zn + 0.95%Pb from 49m. The reconnaissance nature of this drilling makes the presence of mineralisation very encouraging for regional base metal prospectivity and enhances the potential of the base metal targets within Tando’s Mt Sydney Project.
In September 2017 Rumble completed a VTEMmax survey at the Braeside Project which highlighted a multitude of conductors associated with the identified regional base metal trends (refer ASX.RTR Announcement 4 September 2017). Mineralisation has been intersected in drilling at the Barker Well, Cassius Clay, Ragged Hills North and Mt Brockman Prospects, prospects where VTEM anomalies were detected.
In addition a broad coincident magnetic and EM anomaly has been detected in the south of the Mt Sydney project area (Figure 2). While further processing and geological information is required to refine this target it appears to be a deeper-intrusive, larger body . Rumble has stated that the Braeside drill results supported a porphyry related base metal deposit style model and the magnetic and EM anomaly observed at Mt Sydney could be consistent with a target of this nature, or other intrusion related mineralisation styles.

Managing Director Bill Oliver commented:
“The prospectivity of the Mt Sydney Project has been demonstrated by the discovery of surface EM anomalies along regional scale structures, with mineralised intersections now present in drilling along strike. The combined strike length of the Braeside and Mt Sydney Projects implies a mineral system of a significant scale, with systematic exploration required to adequately test such a system and identify where mineralisation may occur.
The presence of a large coincident magnetic and EM anomaly within the project is a very interesting development and a number of mineralisation models will be considered in addition to our current focus on VMS and porphyry targets, including intrusion-related and sedimentary hosted mineralisation.”
The next stage of exploration at the Mt Sydney Project will comprise detailed geochemical surveys and geological mapping to refine targets currently defined by the VTEM anomalies and interpreted structures. More detailed geological and geochemical information will also be collected to advance the coincident magnetic-EM anomaly and determine the nature of the target in this area. These programmes will be designed based on the final VTEM data which is anticipated to be received in February.

APPENDIX 1.
The following Tables are provided to ensure compliance with the JORC Code (2012 Edition) requirements for the reporting of Exploration Results at the Mt Sydney 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. |
Heliborne EM survey of approximately 1,300 line km carried out at 400 metre line spacing using VTEMmax system by Geotech Airborne Ltd. Survey carried out at a flight height of 90 metres with sensor at 35 metres. VTEMmax configuration: 35 m transmitter loop diameter, 700,000 NIA peak dipole moment, 7 ms transmitter pulse width, VTEM receiver Z,X coils |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
VTEMmax system was calibrated prior to the survey at standard testing sites. |
|
| 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. |
VTEM survey has detected targets prospective for mineralisation, the presence of mineralisation is yet to be determined. VTEM surveys are an industry standard practise in early stage exploration for base metals. |

EM measurements taken using VTEMmax system. VTEMmax system calibrated prior to commencement of survey at standard testing sites. All digital data is inspected on a daily basis to ensure that bad data is not present and to identify missing data sections. A preliminary flight path map is plotted and checked against survey specifications. Following completion of the survey all digitally acquired survey data has been merged into a Geosoft Montaj database and checked on a line by line basis. The data presented here is preliminary data and has not undergone any processing to reduce noise or base level adjustments. However following the QA/QC completed by the contractor and the consultant they have advised that the data is suitable for public domain release and anomalism/targets for follow-up will not markedly change following final processing. The “raw” stacked profiles used to generate the anomalies are included in Figure 2. |

| 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. |

No metal equivalent values are being used. | |
| 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’). |
No assays are being reported. |
