ASX and Media Release 13 April 2021
FLTEM AT NARNDEE COMPLETED, MORE CONFIRMED BEDROCK CONDUCTORS
-
FLTEM survey completed with data being processed for final report - expected Mid-April.
-
Two high confidence walk-up, drill-ready targets confirmed (VC1 & VC11).
-
VC7 confirmed as a very discrete bedrock conductor.
-
Moving Loop Electromagnetic (MLTEM) surveying will be conducted over high-priority targets coincident with topographic highs on the DEM.
-
A site visit is being planned for field mapping (identify gossans) and follow-up geochemical surveys with portable XRF to be conducted.
Aldoro Resources Limited ( Aldoro , The Company ) (ASX: ARN ) is pleased to advise its shareholders of the completion of the Fixed Loop EM ( FLTEM ) ( ASX announcement 12 March 2021 ) conducted at the Company’s 100% owned Narndee project ( Project ). The refinement of data and imagery ( ASX Announcement 21 December 2020 ) was the first in a series of sequential steps taken to de-risk the Project to prioritise priority targets for the FLTEM survey. Having now been completed, the FLTEM data’s initial processing has confidently constrained two walk-up, drill-ready targets, being VC1 and VC11. Two additional targets, VC3 and VC7 (Figure 2), have also been confirmed as bedrock conductors and will undergo further definition utilising MLTEM.
The 2DIP geophysical contractors have met with an unavoidable delay, and therefore, it has been decided to bring forward the MLTEM survey (Survey) . The Survey will further discern those anomalies with a very constrained vertical attitude, and additionally, will filter out any SPM responses that may be apparent.
Of interest, several targets are situated on pronounced bedrock highs, identified from the VTEM DEM data, e.g., target VC8. The latter target produced a bedrock conductor near the surface for this broad anomaly, which was interpreted as clays/weathered materials. A site visit and mapping and sampling exercise with a pXRF of these topographical highs will determine the degree of weathering to establish the presence, if any, of clays that may have led to spurious FLTEM readings. The planned site visit will determine the presence of gossanous outcrop relative to historic geochemical soil sampling, as some of the results (e.g., VC1) indicate relatively shallow bodies, which may have a surface expression.
Results of FLTEM Survey:
Target VC1
A total of 8 survey lines were completed (152stns, 8.8km). The Survey was run over the large, high amplitude VTEM response/target which has had limited drill testing in the past. A clear, strong bedrock anomaly was defined over 3-5 primary lines (Figure 1). Although modelling is still to be refined, preliminary results highlight a high conductance source ~8000-18000S+, ~400-500m+ strike/plunge extent, ~50-75m in width, depth to top ~125m, and plunging shallowly toward the NNE.
Due to the quality and nature of the anomaly result and pending checks of historical drilling, geophysical consultants Southern Geoscience Consultants (SGC) recommend that the Company undertake drill testing of the highest conductance core zone. Below is a plot of the preliminary modelling results comprising two model scenarios for the late channels.

Figure 1 . Initial modelling of the VC1 target shows a highly conductive, relatively shallow target of 400-500m strike length and 50-75m width (at left and centre) available for immediate test drilling.
Target VC11
Five survey lines were completed (44stns, 3.0km). The anomaly defines a clear, moderate-strength, localised bedrock conductor present of sufficient detail and quality to provide a robust drill target. The source appears relatively shallow at ~50-75m to its top and is also consistent with the VTEM anomalism position.
Figure 2 is a plot of the preliminary modelling with drillholes targeting the shallower and stronger part of the anomaly defined as blue traces.

==> picture [130 x 73] intentionally omitted <==
Target VC7
A total of 5 survey lines were completed (44stns, 3.0km). A clear, very localised strong anomaly is present in the two central lines, 1800N/1875N (Figure 3), and further modelling is required to confirm this. However, the decays demonstrate a legitimate but very small bedrock conductor. It is also proposed that 1-2 lines of MLTEM would be useful in confirming this interpretation.
The source depth, geometry, conductance, and areal size are still being modelled, however the data shows the source to be relatively shallow at 50m or less to the top. This result is also consistent with the original VTEM anomalism position. Below is a plot of the CH35BZ late channel data with the anomaly defined as the central high/crosshair position.

JORC Code, 2012 Edition - Table 1
Section 1: Sampling Techniques
and Data
| 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. •Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. •Aspects of the determination of mineralisation that are Material to the Public Report.a •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 (e.g. submarine nodules) may warrant disclosure of detailed information. |
•A Fixed Loop Transient Electromagnetic(FLTEM) ground survey completed over 11 high-interest targets. The survey was initiated over selected high priority targets, initially identified from a previous VTEMTM airborne survey. The FLTEM survey commenced mid- February 2021, with all 11 survey blocks completed. Orientation is in E – W direction over EM targets of the Narndee Igneous Complex, identified by UTS Geophysics/Geotech consultants from a previous VTEMTMMax airborne survey.

The Narndee Project is located within the Youanmi Terrane of the Yilgarn Craton, close to a major structural boundary between the Murchison and Southern Cross Domains. Regional geology is dominated by Archaean granite-greenstone terranes (greenstone 2.8-3.0 billion years, granites 2.6- 2.95 billion years) and the Windimurra Group of layered mafic intrusions (2.847 billion +/- 71 million years). These bodies represent the largest layered mafic-ultramafic intrusive complex in Australia. The Narndee Igneous Complex forms the primary component of the Boodanoo Suite and is divided into three broad units of stratigraphy: Ultramafic Zone, Lower Zone and Main Zone. Historic exploration has generally focused on stratiform PGE-reef mineralisation whereas Aldoro’s focus will be on massive magmatic nickel sulphide deposits |

| 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. •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. |
•A listing of the historic Maximus Resources drill hole information material to the understanding of the historic exploration results, along with other historic drilling is provided in the body and appendices of ASX announcement 29 October 2020. •Historic drilling by previous explorers used best practice for that time. •The use of any data is recommended for indicative purposes only in terms of potential Ni- Cu-PGE mineralisation and for developing exploration targets. |
|---|---|---|
| Data aggregation methods |
•In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-of grades are usually Material and should be stated. •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. •The assumptions used for any reporting of metal equivalent values should be clearly stated. |
•Raw composited sample intervals have been reported and aggregated where appropriate. •No metal equivalent values have been quoted |
| 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 efect (eg ‘down hole length, true width not known’). |
•All results referenced are based on down-hole lengths and may not reflect true width of mineralisation or thickness of host lithologies which is unknown |
| 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. |
•Appropriate maps and tabulations are presented in the body of the announcement |
| 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 misleading reporting of Exploration Results. |
•Only selected drill intersections have been mentioned and due to the nature of the drilling and lack of adequate records and survey control, they are considered indicative only and not material |

| Other substantive exploration data |
•Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
•Falconbridge completed an airborne magnetic and radiometric survey over the NIC using a fixed wing aircraft and Scintrex Cesium Vapour CS-2 Magnetometer and Exploranium GR 820 Spectrometer. Lines were flown E-W at 100m spacing and 35m sensor height. This survey was reprocessed by Southern Geoscience. •Aldoro conducted its own VTEMTMMax airborne survey (refer to details in Table 1 ASX Announcement 20 January 2021). |

| Further work | •The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). •Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
•Targets generated from the FLTEM survey, will be followed up with a Moving Loop electromagnetic survey (MLTEM), which will filter super- paramagnetic (SPM) responses, such as that caused shallow magnetite occurrences in weathered ground, that give a similar response to target sulphide bodies. A delay from the geophysical contractor means that the dipole-dipole induced polarisation (2DIP) survey, will now follow the MLTEM survey, and eventually be followed by drill testing. •Exploration is at an early stage and future work will depend on results |
