1. ABSTRACT & INTRODUCTION
This report details all the exploration within EL27877, EL27878 and EL27879 which constitutes
the Daly Waters Project, for the second annual period ending 16 September 2012. The licences
are held by Natural Resources Exploration Pty Ltd and the target commodities are base metals,
diamonds, and phosphate. The dominant activity was the drilling of a 317.2m diamond cored
hole with associated downhole geophysics, measurements and sampling. This drilling was in
collaboration with the Northern territory Government. The drill hole was completed to test
the stratigraphy over the Daly Water Arch structural feature as no exploration has been
previously undertaken within EL27878 area, and the only historical drilling are water bores
with limited available data.
The single drillhole has confirmed the stratigraphy in an area and shown the Proterozoic rocks
to be at around 139 metres depth at this location. Further work is required but initial
observations are they are Proterozoic McArthur Group equivalents. Evidence of sulphide has
been observed including chalcopyrite. Geophysics has shown the region is suitable for electrical
based exploration and a potential target has been generated.
Nine heave mineral surface samples (total 144.77 kg) were also collected and processed during
the reporting period for diamond exploration. The diamond exploration samples were negative
for kimberlite indicators but the extreme wide spacing make this limited sampling inconclusive
at this stage.
2. TENEMENT AND LOCATION The Daly Waters Project consisting of EL27877, EL27878 and EL27879 is located in the central
north of the Northern Territory, approximately 500 kilometres southeast of Darwin. The
township of Daly Waters is situated within an excised portion of the EL27878. EL27905 was
formerly part of the project, but this licence was surrendered effective 21 August 2012. As a
separate Final Report (Munro, 2012) has been lodged activity within this licence is not discussed
further. Full details on the licences are in Table 1. Approved for Annual Group Technical
Reporting has been granted by the Department. All coordinates and maps in this report are
shown in GDA94, Zone 53 datum.
The Stuart, Buchanan and Carpentaria Highways intersect the project area and numerous minor
roads and unpaved tracks cross the tenures. The southern EL27079 is on the eastern side of the
Daly Waters SE53-01 1:250,000 map sheet. EL27878 covers the corners of Hodgson Downs
(SD53-14), Tanumbirini (SE53-02), Larrimah (SD53-13) and Daly Waters (SE53-01) 1:250,000 map
sheets. The eastern licence EL27877 crosses the southern boundary of Hodgson Downs
(SD53-14) and the northern boundary of the Tanumbirini (SE53-02) map sheets (Figure 1).

3. GEOLOGY
The Daly Waters Project tenements are located in the central region of the Mesozoic Dunmarra
Basin, an un-metamorphosed intracratonic basin unconformably part of the Neoproterozoic-
Palaeozoic overlying the Georgina, Wiso and Daly Basins and Palaeoproterozoic-
Mesoproterozoic sedimentary rocks of the McArthur Basin. The Dunmarra Basin is largely
unmetamorphosed and attains a maximum thickness of ~100 meters. No mineral occurrences
are known but potential is thought to exist for diamondiferous kimberlite pipes, phosphates,
base metals and uranium.
The surface geology consists mainly of poorly exposed Tertiary sands and Cretaceous Mullaman
Beds. The last published regional geological overview of the area was in 1969 (Brown, 1969)
4. PREVIOUS FIRST YEAR PERIOD EXPLORATION Main activity during the first annual period was the evaluation of historical exploration activity
and analysis of historical water hole drill chip samples.
4.1 REVIEW OF HISTORICAL EXPLORATION
An extensive review of historic exploration over its Daly Waters Project was conducted. The
earliest exploration on record dates back to 1971 by Comalco which explored for bauxite. Much
of the exploration since this time was for diamonds with a number of companies such as CRA
Exploration Limited, AOG Minerals, Ashton Mining Ltd, De Beers Australia Exploration,
Diamond Mines Australia and Aberfoyle Exploration. A full listing of the available open file
reports as provided in the First Annual Report (Devencorn, 2011).
Significantly no mineral exploration drilling has been completed within current exploration
licenses. Surface sampling for diamonds is restricted to the eastern part of current EL27877 by
Stockdale Prospecting Ltd, CRA Exploration Pty Ltd and Ashton Mining Ltd. A few chromites
were reported but as not microprobe data is available for the grains it is not possible to
speculate on their significance.
The main area of the current licenses has not been sampled at all possibly due to perceived thick
cover (Carpentaria Basin). But the amount of cover is depends on age of the sediments and age
of kimberlite. The kimberlite will be at the depth corresponding to is age in the local
stratigraphic column.
4.2 HISTORICAL WATER BORE CHIP SAMPLING
Selected historical water bore chip samples stored at the Northern Territory Geological Survey
were assayed for a range of metals. A total of thirty water bore chip samples were examined
from the current license area and anomalous levels of zinc, copper, lead and arsenic were
observed. Full details are in First Annual Report (Devencorn, 2011).
4.3 RECONNAISSANCE SITE VISIT
In August 2011 NRE conducted an initial site visit and reconnaissance program around
EL27878, Kalala. Meetings with the landowners were conducted and proposed drill hole
locations were ground inspected to assess their geological and accessibility conditions. NRE
further discussed all foreseen future drill holes with the landowners and the proposed access
to those drill holes along fence lines and existing tracks

smaller ones are microdiamonds, the small orange diamonds are chromites, red circles are
pyrope, and small grey squares are negative samples. Standard 1:100,000 map sheets are
shown.
5. CURRENT PERIOD EXPLORATION
5.1 STRATIGRAPHIC DIAMOND CORE DRILLING
An application was successful for a Drilling Collaboration in respect of EL27878 with the
Northern Territory Government. Under this program, NRE designed three stratigraphic holes
to be drilled. Due to time and budget constraints, only one drill hole NDW12-01 was completed.
The single drill hole was completed by Drillwise Pty Ltd based in Gibson, WA. The initial drill rig
was track mounted, but as this rig was not satisfactory this was replaced with a truck mounted rig
at 210.6m without pulling the rods. The hole was commenced on the 16 May 2012 and the
total depth reached on 7 June 2012 at which point the hole was abandoned. Two crews
worked double shifts over most of the period. The rig was released on the 12 June are failed
attempts to recover the drill rods, and after lowering the polypipe for the geophysics survey.
The hole NDW12-01 was rock rolled to competent ground at 1.4m. No sample was recovered
from this interval. The remaining entire hole from 1.4 to total depth 317.2m was HQ diamond
cored. Drilling was considered exceptionally challenging due to a number of different ground
conditions. A large number of days were lost due to mechanical issues. The core was halved on
site using a diamond saw.
Figure 4. Magnetic Susceptibility down hole.
The location of the hole collar was determined by a Garmin GPSmap 76cs handheld G P S set to
Averaging Mode (one second reading interval) over a 6 hours duration. Location determined
was; Easting (GDA94) 327,000mE; Northing (GDA94) 8,204,914mN; Elevation 210m; UTM Zone
53
The estimated accuracy of the hole collar is within one metre horizontal. A steel plate placed
over the buried collar would enable the collar to be located again with metal detector if
required. Location is shown in Figure 1 and details in Appendix 1.
5.1.1 Downhole Orientation Survey
The orientation of the drillhole was surveyed ever 50 metres down the hole with a Multishot
camera. Overall the hole was very straight and vertical. All magnetic intensity readings by the
survey probe (except the last reading at 300m depth) showed excellent correlation with
expected magnetic field strength (~48000nT) indicating little disturbance to magnetic azimuth.
As the final dip angle was only 0.9 degree from vertical at 300 metres, any slight disturbance of
the azimuth at this depth is not considered significant. See Appendix 2.
5.1.2 Palynological sampling
One s a m p l e from the drilling have been submitted for palynological examination to L.
Stoian from the Geological Survey of South Australia. The sample was from a thin (~1cm) mafic
clay unit (see Figure 3) at 38.4m depth, just above the unconformity with the underlying
limestone.
Figure 3. Thin band of black mudstone (~38.3m) just above dated sample. Scale in cm, top is
up.
The sample is not rich in pollen, spore or dinoflagellate cysts, with only a few taxa counted.
Modern and recent pollen grains were identified including Eucalypthus spathulatha, Casuarina
and Malvacipollis spp. Wood cuticles and phytoliths are present in moderate
frequencies. Marine microplankton include dinoflagellate cysts: Tectatodinium spp.,
Ataxiodinium confusum, Hystrichokolpoma rigaudiae, Apteodinium spp. The majority of the
dinoflagellate cysts are of Neogene age, more likely Late Miocene -Early Pliocene. The unit is
likely to be deposited under neritic marine conditions.
The support of Liliana Stoian, and the Geological Survey of South Australia, Resources and
Energy Group, DMITRE, is appreciated with this work.
5.1.3 Magnetic Susceptibility
The magnetic susceptibility was measured at approximately one metre intervals on
competent sections of the core. The instrument used was a Terraplus KT-10
Magnetic Susceptibility Meter set for HQ core diameter automatic correction. Sensitivity of
this instrument is 0.001x10-3 SI Units. Three readings were recorded on each core piece and the
average determined. All data is provided in Appendix 5. Figure 4 shows the average magnetic
susceptibility down the entire hole.
5.1.4 Petrographic description
Four initial samples were dispatched to consulting petrologist Dr B.J. Barron in Sydney for
detailed descriptions. The small fragments of half core were collected from various intervals to
confirm lithology. The full report is provided in Appendix 9
Two samples were from the limestone formation (138.38m and 134.32m). The first had a with
a mottled texture, the other with fine vugs. Both were confirmed as calcite rich limestone
sediments with little preserved texture. Two samples from the Proterozoic possible McArthur
Group equivalents were examined. At 230.5m the lithology is mudstone, possible lacustrine, and
262.0m depth is finely laminated claystone with possible fossil burrows.
5.1.5 Relative Density
The Relative Density (related to water) was determined on site at around one metre intervals
on suitable competent pieces of whole core. The method employed involved weighing the
core sample on a piece of wire in air, then submerged in water. The scale used was a generic
fishing digital scale of unknown accuracy (likely error could be up to 50g).

mm.
5.1.6 XRF drill core analysis
XRF multi-element analysis was conducted using a Delta X Premium Hand-held XRF (HHXRF)
with Rh anode and 30mm2 Silicon Drift Detector (SDD) over the entire length of hole at
regular intervals. The HHXRF was set to 3 Beam in Soil Mode with capture time of 60 seconds
per beam for a total of 180 seconds analysis time per sample. Measurements were taken
approximately every 1m from start of core (1.4m) to a depth of 12m, then every 5m interval
from 15m depth to end of hole (317.18m). Samples were selected and analyzed directly in the
metal core trays after previously cleaning with water.
XRF analysis was also completed on two sulphide coatings visible along fractures, confirming
one was pyrite and the other chalcopyrite. All data is provided in Appendix 8.
5.1.7 Drill Site Rehabilitation
Following completion of the downhole geophysics the polypipe within the hole was cut around
40cm below surface, sealed, and a thick metal cap placed on top. Soil was then placed back in
the hole over the metal cap. The sumps were then back filled and the original soil spread and
leveled over the site. Figure 6 shows the rehabilitation job completed using equipment and
personnel from Kalala Station.
Figure 6. Rehabilitated drillhole site NDW12-01. Drill sumps were on the right.
5.2 DOWNHOLE GEOPHYSICS
It was anticipated that both downhole TEM and IP dipole-dipole array would be completed to
the full depth of the drillhole. Due to a stuck drill rod string and the caved material above
blocking the hole, only the top half the hole was available for the TEM survey and as the hole
was dry and lined with PVC pipe no IP dipole-dipole could be completed. Full specifications
are provided in the Appendix 10 and interpretation in Appendix 11. The digital data has
previously been submitted (29 June 2012) as part of 'Drilling Collaboration Report Daly Waters
Project' report.
5.2.1 Downhole Transient Electromagnetic Survey
Downhole TEM survey using double 200m square loop centre over the hole, and the TEM sensor
lowered from 2 metres to 152 metres with readings every 5 metres. In conjunction two 200
square loops conventional TEM was completed to compare with and supplement the down
hole TEM.
5.2.2 Downhole Induced Polarisation Survey
Due to the stuck drill rod string down the hole, and the caving collapse of material above the
string the only practical IP survey that could be completed was a Mise a la Masse style survey.
A total of 77 stations were recorded on the surface over an area 400 metres east-west and
160 metres north-south at 40 metre intervals centred over the hole. The in-hole excitation
point was at 156 metres within hole NDW12-01.
5.3 DIAMOND EXPLORATION SAMPLING
During May-June 2011 the diamond exploration activity included surface loam deflation scraps
and stream sediment sampling for heavy mineral kimberlite indicator minerals (Figure 2).
5.3.1 Diamond Indicator Surface sampling
A total of nine (9) samples (144.77 kg total) were collected across the licences. Seven samples
were stream and two were loam sample scapes. These samples were sent to Diatech Heavy
Mineral Services in Perth. One sample, DW12-05 was lost in transit and not included. The
samples are all one standard bag each (around 10L), of minus 1.0 mm material screened on site.
Full sample details, including location coordinates, are provided in Appendix 12. Locations
were determined by handheld Garmin MapGPS 76cs GPS set in averaging mode during the
entire sampling collection time (around half an hour). All of the surface sampling activities
completed have been very low impact and only little rehabilitation at the time of collection has
been required. All stream samples were collected from un-cemented basal sediments in
natural trap sites within the active part of the current drainage. No disturbance to any rock
formations were required.
After the initial DMS concentration at Nagrom (Appendix 13) the concentrates were subject to
further TBE concentration and magnetic separation at Diatech before final visual observation.
Full details on the sample processing and results are provided in Appendix 13 and 14. No
kimberlitic or diamond indicators were observed. A number of grains were selected for
microprobe to confirm their mineralogy and all are not of further interest.
Trace gahnite (zinc spinel) was recovered with DW12-01 just south of Daly Waters, and a few
grains further to the south into EL27879. The number of gahnite grains recovered is decreasing
to the south. No gahnite was recovered in the northeast area of the project (EL27877)
5.3.2 Grain Microprobe Analyses
The selected indicator grains from Diatech were sent to Microbeam Services in Melbourne for
standard microprobe analyses. The grains were mounted in a round epoxy block which is then
grinded in diamond paste till the equatorial section of each grain is exposed and highly polished.
The core of the 27 selected grains were analysed using a Cameca SX50 Electron Microprobe
with four vertical Wavelength Dispersive Spectrometers (WDS). The electron beam accelerating
voltage was 15kV, and beam current 35/25nA. Counting times for all elements is 20 seconds
peak, and with 10 seconds on two backgrounds on either side of the peak position. Detection
limits for all elements better than 0.05 elemental weight percent except for Zn which is 0.09
elemental weight percent.
A lot of the grains were weathered and porous which hindered the quality of the analyses.
Grains identified as garnets were almandine, with minor pyrope components. The single garnet
from sample DW12-01 also had minor (15.6%) gossular component. Other grains were
confirmed as corundum, clinopyroxene and maybe amphibole, all of no further interest to
diamond exploration. The 14 gahnite grains were consistent in their chemistry with average
31.7% ZnO and 56.3% Al2O3 and 3.4% MgO. Full details are contained within Appendix 15.
6. CONCLUSIONS AND RECOMMENDATIONS In an area with little previous drilling the single drill hole has provided valuable information on
the stratigraphy and has shown the Proterozoic rocks to be at around 139 metres depth.
Further work is required but initial observations are the Proterozoic are McArthur Group
equivalents. Evidence of sulphide has been observed including chalcopyrite. The palynological
studies of the sediments that overlie limestone show that they are not from the Carpentaria
Basin (Jurassic- Cetaceous) as expected as the examination indicates a late Miocene-Early
Pliocene age. The anticipated Antrium Plateau Volcanics were not intersected above the
Proterozoic
The sequence intersected would appear transparent in a magnetic survey with no significant
magnetic units measured. The weak magnetic susceptibility readings do have a high correlation
with the observed lithology.
Geological study of the drillhole shows that pyrite was observed within the McArthur sediments
(Figure 5), as well in the Tindell Limestone near the base. A thin film of chalcopyrite was
confirmed at 260.4 metres along a fracture plane. It is significant these were along factures as
this implies mobilisation of sulphides. Minor pyrite was seen along some of the bedding planes
with within the dark grey McAthur sediments.
The hole intersected shallow marine fine sands to clay sediments of likely Late Miocene -Early
Pliocene age to 38.8 metres, overlying Devonian limestone. This limestone unconformably
overlies shallow dipping likely McArthur Basin shales with contact at 139.2 metres depth.
The TEM results did not detect large conducting and chargeable mineralised bodies either
intersecting or as near misses to the drill hole NDW12-01 above an estimated 150 metres depth.
The results also indicated that the shallow part of sediments surveyed at NDW12-01 is
essentially transparent to the type of electromagnetic signals used in mineral exploration. Also,
importantly, there is an absence of the often troublesome 'conductive overburden'
experienced elsewhere in Australia. If these conditions are widespread in this area of the
Carpentaria Basin, the TEM method is practical for large scale surveys seeking to explore
beneath these sediments to look in the basement for electrically detectable ore-bodies like for
instance HYC and Tennant Creek. Such surveys would use a heavy duty system with large loops
energised by high currents and with longer recording times.
The Induced Polarisation results recorded Self potential Apparent Chargeability and Potential
values (similar to Apparent Resistivity) anomalies around the drill hole NDW12-01. The SP
anomalies appear sinuous reminiscent of channels and it is believed that these are caused by
variations in the relatively shallow sediments, probably the top 50 metres. A locus of high
values 80 metres east of the drill hole warrant follow up.
The source of the Apparent Chargeability and Potential values anomalies are typical of a large
disseminated sulphide body. The depth is approximately 150 metres plus. These anomalies
warrant further investigation including drilling.
Because operational matters prevented direct access to the deeper sulphides intersected
by the drill hole NDW12-01, the direct characteristics of these remain untested by the downhole
IP method. If exploration continues in this locality, the sources of the deep and shallow IP
anomalies should be followed up.
To focus drilling for ore-bodies in this area, consideration is being to gravity traversing across
the Daly Waters Arch and airborne magnetic surveying over the tenements, to pin down the
basement depth and structural morphology in more detail.

Daly Waters Report 2012
Hole ID: NDW12-01
Diamond Drilling Program commence on Wednesday 16th May 2012
0-50 Metres
• Rock Rolled to competent ground at 1.4m
• Drilled soft broken ground
• Silting problems started to occur around 35m
• Lost water return around 46m (tried to condition hole but only lasted a couple metres)
50-100 Metres
• Ground started to pressurized through the loss of water and returning further up the
rod string
• Rods kept locking up in this zone • Ream HWT down to 51m to stop zone from caving in and pressurizing, whilst
reaming there was now a cavity from 29m to 41m. This cavity was not there whilst drilling
HQ
• Hole was completely dry thus constantly pulling rods out to grease due to rod chatter
in a dry hole
• Drilled broken with clay zones through out
• Constantly waiting on water as bore was inadequate to service our need to condition
and drill due to no water return
100-150 Metres
• Hole was still dry at this stage thus the constant need to pull out and grease rod string
but grease was being wiped away by wall in a matter of hours
• Constant change in ground condition from broken ground to clay and mud zones
• Drilled swelling Clay zones and rods keep locking up
• Constantly waiting on water as bore was inadequate to service our need to condition
and drill due to no water return
150-200 Metres
• Drilled very broken ground and large patches of swelling clay zones causing heaps of
dramas with core loss and drop core in barrel and down hole thus changed over to HQ3 to
eliminate problems
• Drilled mud stone and didn‟t like any weight on this zone as it will suffocate bit face
and cause very short runs.
• Constantly waiting on water as bore was inadequate to service our need to condition
and drill due to no water return
• Hole was still dry at this stage thus the constant need to pull out and grease rod string
but grease was being wiped away by wall in a matter of hours
200-250 Metres
• Drilled mud stone and didn‟t like any weight on this zone as it will suffocate bit face and cause very short runs, core kept dropping into barrel and in hole
• Constantly waiting on water as bore was inadequate to service our need to condition
and drill due to no water return
• Hole was still dry at this stage thus the constant need to pull out and grease rod string
but grease was being wiped away by wall in a matter of hours
250-300 Metres
• Hole was silting up and tried constantly to condition hole but kept re occurring
• Constantly waiting on water as bore was inadequate to service our need to condition
and drill due to no water return
• Hole was still dry at this stage thus the constant need to pull out and grease rod string
but grease was being wiped away by wall in a matter of hours
• Hole started to cave in
• Unable to put weight on drill string as it would still just plug off upon anything more
than free spin and bog in
300- 310.4 Metres E.O.H
• Hole caving in from above causing silting problems, High Torque and rods bogging
in the hole
• Due to high torque and Bogging from cave-in, Rods keep separating
Strong possibility that the complete rod string will be a right off (approx $40,000 plus transport) Each rod to be tested at end of job. • Constantly waiting on water as bore was inadequate to service our need to condition
and drill due to no water return
• Hole was still dry at this stage thus the constant need to pull out and grease rod string
but grease was being wiped away by wall in a matter of hours
Note: Waiting on water was the biggest unproductive time spent throughout this program
causing anywhere from 1.5 to 4 hour delays every day thus un-enabling us to successfully
condition and flush hole out effectively.
The major cavity that occurred after drilling HQ was at 29 – 41 metres (12) was a major
factor prior to casing that section of. This has occurred in various other sections in the hole to
cause all the constant silting and cave in throughout the program.
Exceptionally challenging drilling

Appendix 7
Palynological analysis and dating of one sample from stratigraphic drillhole
NDW12‐001, Daly Waters, Northen Territory
Author: Liliana M Stoian
One sample from NDW12‐001 stratigraphic drillhole, Daly Waters, has been submitted to Liliana Stoian, Senior Geoscientist, Geological Survey of South Australia for palynological analysis and dating.
The sample was collected by Steven Cooper, depth 38.5 to 38.6m, and represents a black clay layer sitting above an unconformity with underlying limestone, possible Devonian age. Sample size for palynological analysis is about 20‐30g.
Traditional palynological methods were employed including digesting in HCl and HF acids followed by heavy liquid separation (SPT – sodium polytungstate liquit at density 2). No much separation was observed after heavy liquid and all organic material was mounted on a slide using Eukit media. Palynomorph identification was undertaken by the author using a Zeiss Photomicroscope III.
Results
Fossil pollen of Malvacipollis diversus, Haloragacidites harrisii (Casuarina type) and Eucalyptus spathulata are present in very low frequencies. No other pollen grains were present. The palynofloras are difficult to correlate with any palynofloral zones developed in Australia due to lack of any key taxa and species diversity. Pollen of Eucalyptus spathulatha could come from modern eucalyptus species.
Marine microplankton is well represented and include the following taxa: Ataxiodinium confusum, Hystrichokolpoma rigaudiae, Tectatodinium pellitum, Bitectatodinium tepikiense, Apteodinium spp. Similar dinoflagellate cysts are known elsewhere from Neogene and Quaternary and their presence in the sample is associated with a marine event. Species of Bitectatodinium tepikiense and Tectatodinium pellitum are indicators of neritic to oceanic environment.
Sample also contain small amount of grass phytoliths (trapezoid, bilobate and fan shapes). Phytoliths are biogenic silica produced by many plants, very resistant to weathering and preserved in modern soil as well as in older sediments.
The sample does not contain any reworked palynomorphs.
Based on dinoflagellate cysts assemblages and correlation with similar assemblages found elsewhere, the sample is likely to be dated Late Miocene – Early Pliocene.

Detailed petrological examination of four drill core samples
from a stratigraphic drill hole near Daly Waters NT.
Report No: N11/12/1708 29 July, 2012
For: NRE Operations Pty Ltd
Dr B.J. Barron
Consulting Petrologist
Page 1
Sample No. NDW12-01 138.38m
Rock Type Deposit of (?hydrothermal) carbonate (mainly calcite)
comprising poorly defined subparallel layers of undeformed
partly clouded crystals of variable grain size. Accessory
pyrite is present.
Hand Specimen A compact (non-friable) fine grained mid grey (-brown) drill
core sample containing some moderately coarse grains that are well cleaved. The
sample is spongy containing 10% to 20% of small voids. In some domains these occur
in subparallel narrow layers. The sample reacts strongly with cold dilute HCl indicating
abundant calcite.
Thin Section This sample is a deposit of undeformed (?hydrothermal)
carbonate (mainly calcite – see reaction with cold dilute HCl above). The rock is almost
monomineralic and comprises poorly defined subparallel layers of partly clouded
crystals with a variable grain size from less than 0.2 mm (fine sand size) up to crystals
that are optically continuous and more than 4 mm long. An average grain size is about 1
mm.
The carbonate grains mainly have irregular shapes and are
mutually interlocking. The rock contains about 20% of small voids, many of which
show subhedral projections of calcite crystals into the voids. Some carbonate crystals
may comprise two types of carbonate, since coarse host crystals contain abundant
inclusions of a fine grained ?second carbonate with subhedral rhombic shapes
suggesting ?dolomite (or ankerite etc.).
In some elongate interstitial domains are patches of pale
brown, strongly clouded carbonate that could represent an iron-bearing carbonate. This
carbonate is present only in accessory proportions.
The rock is cut by numerous very narrow (less than 0.2 mm
across), subparallel but branching veinlets of late carbonate that is clear of dusty
inclusions. These carbonate veinlets are subparallel to the poorly defined layering.

Page 2
Small spongy and irregular opaque deposits (rarely more
than 1 cm long) also are accessory. Examination in reflected light suggests they are
possibly ?pyrite. Some penetrate along branching mutual grain boundaries and fractures
in the carbonate.
This sample may be identified as a deposit of
(?hydrothermal) carbonate (mainly calcite) comprising poorly defined subparallel layers
of undeformed partly clouded crystals of variable grain size. Accessory pyrite is present.
Sample No. NDW12-01 134.32m
Rock Type Extremely fine grained calcite-rich ?calcrete containing
poorly defined irregular outlines of angular lithic fragments.
It most likely represents a deposit of exceptionally fine
grained, reworked (?aeolian) and recrystallised microfossil
clasts.
HandSpecimen A compact (non-friable) fine grained, mottled pale grey and
very pale grey sample, in which pale grey material could represent ?irregular fragments.
Some of the latter could contain very fine sand sized ?clasts. Both fractions react very
strongly with cold dilute HCl indicating calcite.
Thin Section This sample has undertone intense, extremely fine grained
alteration to almost monomineralic carbonate. The carbonate is calcite (see strong
reaction with cold dilute HCl above), which has an average grain size of about 0.03 mm.
Nevertheless, there are poorly preserved outlines of possible lithic fragments that have a
variable size, and reflect those defined in the hand specimen. The largest of these in the
present section reaches nearly 4 mm long.
Although the fragments are now exceptionally fine grained
calcite, they also contain irregularly disseminated, very fine grained (rarely more than
0.02 mm) translucent to near opaque granules that partly define abundant rounded and

cuspate small shapes (mainly less than 0.05 mm) that could represent broken
?microfossil remains.
The rock contains small patches (mainly less than 1 mm
across) of poorly crystallised subradial chalcedony. Some patches are intergrown with
minor cherty quartz. Most are also intergrown with small patches of fine grained
carbonate. Sparse voids and veinlets are partly coated with translucent red-brown
hematite and are partly filled with coarser grained granular carbonate. This reaches 0.6
mm grain size in the present section.
This sample most likely represents a deposit of exceptionally
fine grained, reworked (?aeolian) and recrystallised microfossil clasts and may be
identified as extremely fine grained calcite-rich calcrete containing poorly defined
irregular outlines of angular lithic fragments.
Sample No. NDW12-01 230.5m
Rock Type Exceptionally fine grained claystone deposit with
compaction layering. Dusty oxides once could have been
iron-bearing carbonate. It is most likely a shallow lake
deposit.
Hand Specimen A friable, mid red-brown ?hematite-rich finely laminated
sample, containing sparsely disseminated small pale grey spots. These are less than 1
mm diameter. The sample lacks reaction with cold dilute HCl and therefore lacks
calcite. The sample is not magnetic.
Thin Section This sample is a deposit of finely laminated ?compaction
foliated claystone that is crowded with small opaque ?oxide granules and partly stained
by red-brown hematite dust. It comprises almost equally abundant lensed narrow
domains, some of which have irregular shapes and reach more than 5 mm long but only
0.5 mm thick, of very fine grained low birefringent clay ± birefringent ?smectite clay
that is little-stained by patchy red-brown hematite. The elongate lensed domains are set

Page 4
in host rock that is also clay-rich (possibly mainly smectite clay), stained by red-brown
hematite dust. The latter contain relatively more abundant opaque granules.
Also present are sparse elongate „spots‟ of clouded
birefringent clay, some of which have subhedral shapes and may replace crystal sites.
These domains also contain relatively few opaque granules compared with the host
rock.
The sample contains sparse subhedral opaque ?oxide crystal
sites up to about 0.2 mm that account for about 3% to 5% of the present section area.
Very rare small angular grains (mainly less than 0.06 mm grain size) are quartz. These
are present only in one domain and may be secondary.
This rock lacks recognisable relict texture but is not a normal
sediment. It could represent an exceptionally fine grained claystone deposit with
compaction layering. Dusty oxides once could have been iron-bearing carbonate. It is
most likely a shallow lake deposit.
Sample No. NDW12-01 262m
Rock Type Fine grained, very finely laminated sparsely silty claystone.
The sample contains a structure interpreted as a micro-
?worm burrow.
Hand Specimen A fine grained, very finely laminated mid-grey, fairly
compact (not friable) drill core sample, containing visible small reflective ?detrital mica
flakes parallel to layering (?bedding).
ThinSection Unlike the previous sample, the present rock retains a clear
clastic sedimentary texture and is sparsely silty claystone.
Silt sized (<0.05mm) detritus is angular and dominated by
thin mica flakes, a few of which are bent and deformed. Angular quartz is slightly
NRE Operations Pty Ltd Dr B.J. Barron
Jul-12 Petrologist
Page 5
subordinate. The detritus accounts for less than 10% of the present section area, and has
a somewhat patchy distribution.
Mica flakes are strictly parallel to a compaction foliation and
mainly are less than 0.15 mm long but less than 0.01 mm thick. They are dominated by
birefringent ?„sericite‟ and few are pale brown to almost colourless pleochroic micas
that are most likely degraded biotite. Also present are sparse similar sized thin
carbonaceous flakes.
The micas account for about 5% to 7% of the section area.
Accessory detritus comprises mid green tourmaline, small green chlorite flakes, apatite,
zircon and small opaque oxide grains.
The recognisable fine grained detritus is set throughout an
abundant rock matrix of very fine grained wispy birefringent ?‟illite-smectite‟ clay,
wispy flakes of which rarely exceed 0.03 mm long. The abundant flakes define a
?compaction foliation direction and are subparallel to the larger wispy detrital mica
flakes.
A disrupted irregular domain more than 3 mm long and up to
0.5 mm across, is oriented normal to the layering. This could represent a micro- ?worm
burrow. Several of these structures are present.
This sample may be identified as fine grained, very finely
laminated sparsely silty claystone. The sample contains a structure interpreted as a
micro- ?worm burrow.

1. SUMMARY
In May and June 2012, Zonge Engineering and Research Organization (Zonge) mobilised
a two-person geophysical field crew to the Daly Waters Prospect in the Northern Territory
to conduct Down-Hole Induced Polarisation (DHIP) and Down-Hole ElectroMagnetic
(DHEM) surveys for NRE Operations.
The crew initially mobilised on the 25th
of May however due to drilling on hole NDW12-
01 not being completed the crew demobilised on the 30th
of May back to Adelaide. The
crew re-mobilised on the 10th
of June and completed DHEM, Mise-a-la-masse (MALM)
and coincident loop EM surveying before final demobilisation on the 16th
of June. Much
of the DHEM and all of the DHIP surveying planned could not be performed due to the
hole being blocked by abandoned drill string at approximately 156m from surface.
Survey planning and interpretation of data was performed by David Tucker of Gawler
Geoscience.
Data quality and repeatability were monitored throughout the course of the survey which
ensured that the best possible data were acquired given local conditions and time
constraints.

2. INSTRUMENTATION and SURVEY PARAMETERS
A Zonge multipurpose GDP-32II
receiver was used to take all of the MALM data for this
project. MALM data were recorded in pole-pole mode using non-polarisable porous pots
filled with copper sulphate as receiver electrodes. Data were acquired in time domain at a
frequency of 0.125hz allowing acquisition of potential voltage (Vp), self-potential (SP)
and chargeability (Mx).
MALM transmitted fields were generated with a Zonge ZT-30 geophysical transmitter
connected to electrodes on the surface some distance from the hole and the second placed
down the hole at approximately 156m from surface. Synchronisation was controlled via a
Zonge XMT-32 transmitter controller.
An EMIT Smartem V receiver and controller were used to acquire data and control the
Zonge ZT-30 transmitter respectively for the DHEM and EM sounding acquisition. For
DHEM acquisition a Geonics BH43-3D coil probe was used with data recorded on each
X, Y and Z components at a frequency of 2.083 Hz. Readings were taken at 5 metre
intervals between 2-152 metres from surface. Source fields were produced using a 2-turn
200x200 metre transmitter loop. Coincident loop EM soundings were acquired at two locations separated by 200 metres
near NDW12-01. Readings were taken using a 1.25 Hz frequency using a single turn 200
metre transmitter and receiver loop.
The raw data from each day was downloaded every evening from the receiver's internal
memory to a laptop computer before being sent to Zonge‟s Adelaide office. Final
processing, plotting and modelling were completed in Zonge's Adelaide office.

3. PRODUCTION ISSUES
Substantial delays occurred during the survey due to delays in the completion and casing
of the hole, during this time the crew were on standby. The planned down-hole surveying
was only possible to a limited degree due to the reduced access resulting from the stuck
drill string from 156 metres and below.
As a result of the limited opportunity for down-hole surveying alternative techniques to
better utilise the hole and understand subsurface electrical structure were performed.
No safety related incidents occurred during completion of the survey. Detailed information on daily production may be found on the accompanying disc under
"Production Reports". Additional information about safety issues may be found on the
same disc under "Safety _Documentation".
4. PRODUCTION SUMMARY
Appendix I provides a Summary of the Production of Job 967. More detailed information
on daily production may be found on the accompanying disc under "Production Reports".

5. DATA PROCESSING
The quality of each block of raw DHEM, MALM and MLEM data was examined before
being averaged to create a single record for each receiving station. Data points that were
considered of poor quality were skipped before averaging each station‟s data.
DHEM data were edited and reviewed using EMIT‟s Agent99 software before primary
field rotations to produce rotation corrected A, U and V components for output. Resulting
rotated A, U, V data are presented in Apendix II where both log and linear signal
magnitude scales are presented. A single resistivity sounding inversion model of vertical
component (A/Z) coil data was performed on data acquired at 2m below surface in
NDW12-01 as a proxy surface in-loop reading. It should be noted however that the
proximity of the 4x4 vehicle and winch used in surveying may have had an undesired
effect on this sounding and resulting modelled resistivities.
Mise-a-la-masse data were edited as per above and imported into an excel spreadsheet
(NDW12-MALM.xlsx) within which the apparent resistivities were calculated. Apparent
resistivity calculations were performed assuming a point source at 156 metres down-hole,
the coordinates of the remote transmitter and receiver electrodes were taken into account
in the apparent resistivity calculations. The location of the remote transmitter and receiver
electrodes are recorded in the 967_MALM.stn file accompanying this report.
Chargeability values are “Newmont Chargeability” values recorded by the GDP receiver
and reflect an integration of decay window magnitudes over the 450-1100ms after
transmitter turnoff. Potential voltage and self potential values as plotted in Appendix III
are averages of those recorded by the receiver.
Coincident loop EM data were reviewed using EMIT‟s Agent99 software before being
output and imported into Zonge‟s STEMINV software for 1D inversion. 1D resistivity
sounding profiles over depth are presented in Appendix IV. It is possible that the
remarkably low resistivities modelled for sounding 324350 are the result of SPM effects
commonly seen in coincident loop EM data.
All raw and processed data, location data and documents associated with this survey are
presented on the accompanying disc.

Downhole Geophysics in Drillhole NSW12-01

1. Executive Summary A downhole geophysics program was undertaken in drillhole NDW12-01 by Zonge
Engineering Pty Ltd (Zonge) for NRE Operations Pty Ltd (NRE) from 27 May 27 to 16 June
16 2012. The geophysics program was supervised by Dr David H Tucker of Gawler
Geoscience (Geoscience).
The aim of the program was twofold:
1. To measure electrical characteristics of the geological section, and
2. To search around the hole for conductive and chargeable mineralisation.
The geophysics was undertaken within the Geophysics and Drilling Collaborations program.
Table 1: Summary of geophysical methods used and interpretation.
Geophysical Method
Outcome
Interpretation
Induced Polarisation dipole-dipole array in hole (1 metre electrode spacings).
Not conducted. Open hole situation water filled situation not available (lined with PVC pipe)
n.a.
Induced Polarisation Mise-a-la- masse with excitation point downhole.
Conducted. Electrode located at
156m at bottom of PVC in available part of drillhole (sulphides recognised in drill core at approx 183 and approx 240 metres depth were not directly accessible).
A Chargeable conducting zone lies in northwest of gridded area. Not closed by survey. Source estimated to lie approx 150+ metres. Possible disseminated sulphides. Also SP indicates sinuous anomalies interpreted as shallow channels less than 50 metres deep.
TEM in hole with multiple surface loops used for excitation.
Conducted. Twin 200 m loop used: and 2m -152 m of hole successfully surveyed at 5 metre stations
Flat response. No off-hole conductors recognised. Sounding models indicate 1-D geo-electric section of: from surface Apparent Resistivities of approx 10-20 Ohm.metres, rising to approx 500
Ohm.metres at approx 140 metres depth. Then falling off with
increasing depth.
TEM remote from hole for reference purposes.
Conducted. 200m coincident loops. Two stations observed, edge on edge.
Sounding models indicate 1-D geo- electric section of: from surface Apparent Resistivities of approx 40- 50 Ohm.metres, rising to approx 160 Ohm.metres at approx 230
metres depth. Then falling off with increasing depth.
The hole was drilled with HQ rods to 317.2 metres depth by Drillwise Pty Ltd (Drillwise). A
complete HQ drill string was abandoned in the hole from approximately 167.1 metres to TD.
PVC was run for 156 metres and only this upper section was open geophysics probes.
There was a blockage to probes below this.
A Mise a la masse IP survey was conducted on a grid 400 metres East-west by 160 metres
North-south. There was no sulphide zone directly accessible, therefore an excitation
electrode for the work was located at 156 metres in NDW12-01 at the bottom of the hole as
only option. The remote current and receiver electrodes were located approximately 650
Page 2 of 30

metres to the South and to the North respectively. Voltage and induced polarisation
measurements were made on a grid with stations 40 metres apart.
Anomalous IP results were recorded in Self potential, Voltages, Apparent Chargeability and
are evident in Apparent Resistivity estimates calculated from the values. There are two kinds
of anomaly patterns: those detected by Self Potential are sinuous and reminiscent of
channels in sediments; those detected in Apparent Chargeability, Voltages and Apparent
Resistivity are more elliptical in character and are not closed off in the North. Both kinds
extend at least 200 metres past the drillhole and out of the surveyed area.
The depth to the sources of the sinuous anomalies is estimated at less than 50 metres.
Sources may be sulphides or more likely clays in shallow channels.
The depth to the more elliptical anomalies is estimated at 150+ meters. The geological
source of the anomalies is not known. The source is likely to be disseminated sulphides.
Both kinds should be followed up.
Downhole TEM readings were acquired at 5 metre depth intervals from 2 to 152 metres
using an energised dual 200 metre square loop centred over the drill collar.
Results indicate that the downhole TEM survey did not detect significant conducting bodies
either intersecting the drillhole, or within the reach of the excitation footprint of the 200 metre
loop. It is believed that this footprint amounts approximately to a cylinder of rock 200 metres
across and extending from the surface to 150 metres.
The abandoned drill rods which lie in the hole approximately 10-15 metres directly below the
deepest station with the TEM probe were not clearly detected, probably because of poor
coupling. Their influence appears to be weak.
The implication for exploration of the TEM results available from this survey is that bothe IP
and TEM electrical geophysics methods could be useful for deep exploration for conductive
ore-bodies in this area. For this purpose, large loops and high current strengths and large
dipoles and high currents should be considered.

2. Introduction A downhole geophysics program was undertaken in drillhole NDW12-01 by Zonge
Engineering Pty Ltd (Zonge) for NRE Operations Pty Ltd (NRE) from 27 May to 16 June
2012. The geophysics program was supervised by Dr David H Tucker of Gawler Geoscience
(Geoscience).
The aim of the geophysics program was twofold:
1. To measure electrical characteristics of the geological section encountered in the
hole, and
2. To search around the hole for conductive and chargeable mineralisation.
The geophysics was undertaken within the Geophysics and Drilling Collaborations program.
This logistics of the field operations is illustrated in this report by pictures taken in the field by
the author. Various diagrams produced by the author and by Zonge are included to present
the results and interpretation. A location map is shown as Figure 2 below.

3. Drillhole Characteristics Drillhole NDW12-01 is located in EL27878 approx 10km Northwest of Daly Waters at
coordinates shown in Table 2.
Table 2: Drillhole NDW12-01 Location.
Drillhole East_WGS84 North_WGS84 Elevation_m UTM_Zone Depth_m Dip_angle
NDW12-01 327,000 8204914 210 53 317.2 -90
The hole was drilled with HQ rods to a surveyed total depth (TD) of 317.2 metres. Of this,
approximately 156 metres was open and available for geophysics. Below that, the hole was
not accessible due to an intervening blockage, likely comprised of collapsed rock and mud.
A schematic of the situation is shown in Table 3.
To prevent collapse, the top 156 metres was lined with 48mm internal diameter PVC pipe
opened at the bottom. The installation method used was to glue and run down the six metre
long PVC pipes within the HQ drill string to the bottom of the hole. When at TD, the HQ rods
were withdrawn, leaving the PVC in situ.
Before undertaking geophysical surveys a heavy ‘dummy’ weight, approximately one meter
long, was lowered on a rope to test the characteristics of the pipe and the blockage. The
dummy would not pass beyond the bottom of the PVC and raising a few metres and
dropping a few metres did not help.
From 167.1 metres to total depth (TD) the drillhole contained a stuck string of HQ drill.
The water table was estimated by drillers to lie at approximately 140 metres below surface.

4. Regional Context The geology of the locality is recognised as Karumba Basin sediments overlying Carpentaria
Basin sediments overlying probable Georgina Basin sediments and these in turn overlying
possible McArthur Basin metasediments and/or Tennant Creek rocks (Warramunga Group).
A regional map is included as Figure 1.
There is no known on-line open file summary available of electrical characteristics of
sediments in this area and in particular there is no known geo-electric section available.
Electrical data may exist within company reports (Roger Clifton pers. comm.) but was not
pursued here.
The regional gravity for Australia, available on the AGSO website and NT website, indicates
that the drillhole is located on a regional Bouguer anomaly high anomaly. This is named the
Daly River arch. This ‘arch’ is a narrow, 10-20km wide North-south striking gravity anomaly
which extends for more than a hundred kilometres, and is of regional significance. The
anomaly morphology, and in particular its marginal gradients, is generally poorly defined by
the 11 km spaced helicopter gravity stations and rare detailed road traverses. One such road
traverse, which extends East-west along the Borraloola Highway and also the Buchanan
Highway, gives some indication. The Buchanan Highway gradient indicates a steeply dipping
density contact, probably a fault on the west side. The depth to the source of the gravity
anomalies has not been modelled and is not known.
There is only weak correspondence between aeromagnetic patterns and the North-south
gravity anomaly high, perhaps indicating that they have different sources. Several estimates
to magnetic basement made by the author (from the low quality regional aeromagnetic data
within the area of EL27878) lie in the range 300-600 metres. The dominant magnetic pattern
indicates a 30km wide suite of approximately 305 degree bearing narrow linear anomalies
through and beyond the EL27878. These responses are typical of dyke swarms intruding
faults. It is speculated they are attributable to magnetic Antrim Plateau Volcanics. Vague
pattern breaks, probably attributable to faults, strike through the EL27878 past drillhole
NDW12-01 on a strike of 020 degrees.
In conclusion, it is likely that the Daly River arch gravity anomaly is caused by a narrow sliver
of higher density basement forming a topographic high, perhaps bounded by steeply dipping
faults. An analogy with the Emu Fault and the localisation of the HYC ore body is relevant.

5. Transient Electromagnetic Survey 5.1. Equipment and layout for downhole TEM survey
The downhole TEM survey as undertaken required an energising loop to be laid out on the
surface and for readings to be taken at intervals down the drillhole. A schematic diagram of
the set up is shown in Figure 3. A set of pictures taken in the field by the author to illustrate
the work is included in this report (Figures 4 to 10).
A full description of the operational procedures and digital copy of the results are included in
Zonge’s logistics report (Mann, 2012).
An EMIT Smartem V receiver and controller were used to acquire data and control the
Zonge ZT-30 transmitter, which was supplied with power from a Honda 3 KVa generator, for
the downhole TEM acquisition.
The downhole probe was a Geonics BH43-3D coil probe with data recorded on each X, Y
and Z component a a frequency of 2.083 Hz. The system used 33 time windows from 0.14
to 141 milliseconds and these are provided in the following table (Table 4).
Table 4: Smartem V sampling windows (milliseconds).

A conventional, square, dual loop was chosen for this survey, with 200 metres per side,
oriented North-south East-west and with the hole at the geometric centre. Such a loop would
couple with a flat conductor intersecting or lying close to the hole. In operation the current
through the loop is governed by the wire resistance and the transmitter capacity and in this
instance was 0.56 amperes.
The loops were laid through light scrub, which did not require cut lines.
Readings were taken in the hole with the probe lowered in 5 metre stops, with the sensor
location of the probe starting 2 metres below surface and extending to 152 metres below
surface.
An option considered, but not adopted because the hole was not open to its full depth, and
the results did not warrant further work, was to lay out several other adjacent loops cornered
on the hole to search for extensions of any conductors away from the hole.

5.2. Results and interpretation for downhole TEM
The data obtained by the TEM downhole survey were processed by Zonge in Adelaide and
plotted profiles of these results are shown below (Figure 11).
The plot shows three sets of profiles. The ‘A’ component is axial to the hole and because the
hole is vertical, is also a vertical vector component.
The ‘U’ component and ‘V’ components are North and South vector components. These
latter components can be useful if conductive mineralisation is encountered and can give an
indication of direction of extensions to such.
The units used for the TEM results are microvolts per ampere of current flowing in the loop
and are thus normalised: the scale used in the diagram is logarithmic: horizontal units are
metres from surface, with surface at the left.
The A component shows a very smooth and essentially flat set of profiles. There are no
strong obvious anomalies as might be expected if significant conductors were present
intersecting the hole (confirming what is known from the geological logging).
On close inspection, the early time channels in the A component results show a gentle rise
in amplitude from surface to peak at approximately 35 metres depth. Below approximately
75 metres, there is a very slight and gentle rise in amplitude of all channels towards the
bottom of the set of observations. It is suspected that this may represent a response from
the drill rods.

Close inspection of the U component and V component shown here shows weak inflections
at approximately 10-15 metres, 60-65 metres 100-105 metres and 110-115 metres. These
do not show corresponding anomalies in the A component. There is a weak correspondence
with geologically observed unconformities: as such, the inflections may indicate weak
conductivity changes associated with these unconformities.

To illustrate the characteristics of the TEM data, decay curve plots are included here for the
33 channel sample taken at the two metre depth point, i.e. for the shallowest sample of the
drillhole and for which the geometry is best understood. Curve fits of two types are applied
where appropriate: power curve fits and time constant fits (Figures 12-15).

A one dimensional inversion was run by Zonge on this shallowest observation dataset at two
metres depth and the result is shown in Figure 16: the drillhole data were treated as a
surface observation for the purpose of comparison with moving loop values discussed
below. This approach provided a result equivalent to a depth sounding which is normally
only possible for each station of a moving loop configuration TEM survey. As such, the
drillhole result can be directly compared to moving loop data.

The smooth sounding model probably indicates a three layer case applies as indicated in the
1-D sketch above (Figure 16). The figure shows corresponding geological notes alongside.
It is noted that the estimated 20 ohm metre section to approximately 40 metres corresponds
approximately with an unconformity noted in drill core at approximately 39 metres.
Below that porous limestone was encountered in drillcore to a disconformity at approximately
140 metres which is also approximately the water table: this depth corresponds to the peak
values calculated in the resistivity model of 500 ohm metres.
Below 140 metres in the sounding model the resistivities drop off to a minimum at
approximately 400 metres.

5.3. Moving loops layout for surface TEM sounding survey
Two surface TEM soundings were taken using coincident 200 metre loops at a location
approximately 1.5 kilometres Northwest from drillhole NDW12-01 (see Figure 2).
An EMIT Smartem V receiver and controller were used to acquire data and control the
Zonge ZT-30 transmitter supplied with power from a Honda 3 KVa generator for the
downhole EM sounding acquisition.
5.4. Results and interpretation for surface TEM sounding survey
A one dimensional inversion model of apparent resistivities run on the data by Zonge is
included here (Figure 17). It indicates a three or possibly four layer model applies at this
location.

From surface to approximately 50 metres depth resistivities peak at approximately 55-60
ohm metes; from 50 metres to approximately 130 metres values drop to approximately 40-55

6. Induced Polarisation survey 6.1. Equipment and layout
To investigate the Apparent Resistivity and Chargeability characteristics of the geological
section in this drillhole, and in particular of the intersections of sulphides encountered at 183
and 240 metres, it was planned to run an Induced Polarisation survey using a small dipole-
dipole array (one metre ‘a’ spacing and ‘n=1’). Such a survey requires a water-filled open
hole. Because the available hole was not water-filled, this option was not possible to
implement.
A secondary plan, to run a Mise a la Masse style of survey (Mudge, 2004: Hauck, 1970) to
test for possible extensions of any significant sulphides encountered and identify any ‘near
misses’, was finally run in modified form. The survey layout is indicated in Figure 2 in the
Introduction. The layout at the drillhole is shown in Figure 18. Operational pictures taken by
the author are included as Figures 19 to 23.
The equipment used included a Zonge multipurpose GDP-3211 receiver recorded in pole-
pole mode using non polarisable porous pots filled with copper sulphate as receiver
electrodes. Data were acquired in time domain at a frequency of 0.125hz allowing
acquisition of potential voltage 9Vp), self-potential (SP) and chargeability (Mx).
Transmitted fields were generated with a Zonge ZT-30 geophysical transmitter connected to
electrodes on the surface some distance from the hole and the second placed down the hole
at approximately 156m from surface. Synchronisation was controlled by a Zonge XMT-32
transmitter controller.
Ideally this kind of test calls for the current electrode to be planted directly within each zone of
mineralisation. However, because the known sulphide sections were in the blocked-off part
of the hole, it was only practical to do the next best and plant the current electrode at the
deepest point reachable and use this as a current injection point. By this means, the survey
in effect can search above the current injection point.
Induced Polarisation readings were obtained at 40 metre stations on a grid of overall
dimensions 400 metres East-west by 160 metres North-south centred on the drill collar. The
in-hole excitation point consisted of a one metre length of 25mm copper rod at 156 metres
depth presumably located in mud. Approximately two kilograms of copper sulphate in water
were poured into the drill pipe to improve conductive contact with surrounding rock. A
second electrode for current input was located as an infinity point approximately 650 metres
to the South. Readings were taken at moving porous pots located at grid points and at an
infinity point located approximately 650 metres to the North.

6.2. IP Results and interpretation
Four plots of results are included here: Self Potential, Apparent Chargeability, Potential, and
Apparent Resistivity (Figures 24 to 27). The grid extends 160 metres North-south and 400
metres East-west and the drillhole and the current injection point lie beneath the geographic
centre of the grid.
Anomalous IP results were recorded in each of the Self Potential, Apparent Chargeability
and Potential. Anomalies and Potential and in Apparent Chargeability are essentially linear
in pattern, have an overall East-west strike and extend at least 200 metres past the drillhole
and out of the surveyed area.
Surprisingly high values of Apparent Chargeability (up to 35 milliseconds in the pink area of
Figure 25) were recorded in the Northwest of the grid. This corresponds approximately to an
area low in Potential low (blue values Figure 26), which in turn allows calculation of Apparent
Resistivity low values marked as deep purple (Figure 27). Such correspondence of high
values of Apparent Chargeability and Low Apparent Resistivity is often associated with
sulphides.
It is notable that in each of these set of responses there is no obvious concentric pattern of
contours around the drillhole. Rather we see a half closed concentric pattern in Apparent
Chargeability centred some 150 metres or more to the Northwest of the drillhole. This is an
unusual and key result. This may indicate that the IP method didn’t connect with significant
conductive or chargeable bodies close to the current injection point, i.e. at 156 metres.
Rather, the IP connected with a separate body at least 150 metres away and below the
Chargeability high. Estimated depth to the source is approximately 150 metres plus.
It is recommended that the anomalies are followed up.
The Self Potential is a measure of natural voltaic response of an area, and a high zone can
indicate oxidising sulphides beneath. In the area around NDW12-01 the higher responses in
Self Potential, as indicated by the pink coloration in the figure, lie in sinuous patterns over
the grid, different from the other responses. This suggests a different kind of source from
what is observed in the Potential and Apparent Chargeability. The sinuous patterns are
suggestive of channels in a floodplain. These responses may indicate variations in clay
content of shallow channels at less than 50 metres depth. The highest results as evidenced
by three stations are centred approximately 80 metres East of the drillhole.
The geological source of the anomalies is uncertain. Sulphides are possible: alternatively
clays are also possible.

Figure 25: Apparent Chargeability. The drillhole and current injection point lies at the centre of the grid. High vales, such as those in the northern part of the grid commonly indicate disseminated sulphides.

7. Conclusions and Recommendations 1. Conclusion TEM: Because NDW12-01 was blocked halfway down and essentially
dry, testing of geophysical characteristics of the rocks intersected by the drill was
limited in scope.
2. Conclusion: TEM: The TEM results did not detect large conducting and chargeable
mineralised bodies either intersecting or as near misses to the drillhole NDW12-01
above an estimated 150 metres depth.
3. Conclusion TEM: Implications for future exploration. The TEM results indicate that
the shallow part of sediments surveyed at NDW12-01 are essentially transparent to
the type of electromagnetic signals used in mineral exploration. Also, importantly,
there is an absence of the often troublesome ‘conductive overburden’ experienced
elsewhere in Australia.
4. Recommendation TEM: If these conditions are widespread in this area of the
Carpentaria Basin, the TEM method is practical for large scale surveys seeking to
explore beneath these sediments to look in the basement for electrically detectable
ore-bodies like for instance HYC and Tennant Creek. Such surveys would use a
heavy duty system with large loops energised by high currents and with longer
recording times.
5. Conclusion IP: The Induced Polarisation results recorded Self potential Apparent
Chargeability and Potential values (similar to Apparent Resistivity) anomalies around
the drillhole NDW12-01. The SP anomalies appear sinuous reminiscent of channels
and it is believed that these are caused by variations in the relatively shallow
sediments, probably the top 50 metres. A locus of high values 80 metres east of the
drillhole warrant follow up.
6. Conclusion IP: Implications for exploration. The source of the Apparent Chargeability
and Potential values anomalies are typical of a large disseminated sulphide body.
The depth is approximately 150 metres plus. These anomalies warrant further
investigation including drilling.
7. Conclusion IP: Because operational matters prevented direct access to the deeper
sulphides intersected by the drillhole NDW12-01, the direct characteristics of these
remain untested by the downhole IP method,
8. Recommendation IP: If exploration continues in this locality, the sources of the deep
and shallow IP anomalies should be followed up.
9. Recommendation General: To focus drilling for ore-bodies in this area, consideration
should be given to gravity traversing across the Daly River arch and airborne
magnetic surveying over the tenements, to pin down the basement depth and
structural morphology.
