High-grade zinc intercept of 20m @ 12.05% Zn in latest drilling at Sulphur Springs

Includes a spectacular zinc interval of 4m @ 20.8% Zn

Highlights

  • Drill hole SSD094 intersects four zones of zinc mineralisation with the best result being:

  • 20m @ 12.05% Zn from 83m, including

    • 4m @ 20.8% Zn and 2.67% Pb from 99m
  • (Note: intervals are reported as down-hole intersection widths)

  • Drill hole SSD093 intersected three zones of copper mineralisation with the best result being 6.1m @ 2.28% Cu from 97m, plus a further two zones which were also associated with zinc mineralisation.

  • Three further holes (SSD095, SSD096 and SSD097) have been completed, each intersecting significant widths of semi-massive to massive sulphides with visible copper and zinc sulphide minerals.

  • Tenth diamond drill-hole, SSD098, currently in progress.

Venturex Resources (ASX: VXR) is pleased to report further high-grade assay results from its ongoing in-fill drilling programme targeting shallow mineralisation at its 100%-owned Sulphur Springs Copper-Zinc Project, located south- east of Port Hedland in WA.

Commentary

Today’s release marks a number of important milestones for the current drill program, including:

  • Hole SSD094, which is the first hole in the programme to intersect significant widths of zinc mineralisation. This could be an exciting development as this part of the orebody is currently interpreted to be predominantly copper-rich. The pending assay results from holes SSD096 and SSD097, drilled a further 20m to the west of SSD093, will provide a valuable insights as to whether this represents the potential development of a new zinc zone extending to the west or is a more localised event.

  • The results from SSD093 are more in line with the current interpretation, which sees the copper lens pinching out to the west. The pending assay results from holes SSD095 and SSD096 will help to confirm the extent to which the copper mineralisation extends to the west.

  • More broadly, today’s results and the visual observations from holes SSD095 and SSD096 (drilled 20m further to the west) have potentially important implications for the broader exploration potential at Sulphur Springs. Based on the drill results released to date and visual observation of holes SSD095 and SSD096, it is apparent that the broad semi-massive to massive pyrite sequence which hosts the copper and

zinc mineralisation is still well developed. Subject to pending assay results and ongoing geological review, this could open up a new area of exploration to the west.

  • Holes SSD089 – SSD096 (Phase 1) mark the completion of eight of the 11 planned holes targeting the enriched upper part of the orebody (see ASX release – 4 September 2017). Holes SSD097 and SSD098 are the first holes of Phase 2 of the current program, which are designed to test Inferred Resources within the lower part of the planned open pit. The remaining planned holes require the rig to be moved back to the east prior to drilling.

Drill-hole details

Drill hole SSD093: (728800mE/7659670mN, vertical) was drilled 20m to the west of previously released holes SSD091 and SSD092 (see ASX release – 1[st] November 2017) with an RC pre-collar through the hanging wall units consisting of chert, siltstone and intercalated volcanic rocks to 96.7m. Gossan textures were observed throughout the pre-collar. A PQ3 diamond tail completed the drill hole to 133.3m and intersected 29m of semi-massive and massive sulphide from 91m to 120m (see figure 1).

The zone of semi massive to massive sulphide returned assays of:

  • 6.1m @ 2.28% Cu from 97m including

  • 3.1m @ 4.96% Zn and 2.25% Cu from 100m .

  • Two further lower zones returned

  • 4.45m @ 1.88% Cu from 114.65m and

  • 1.1m of 25.2% Zn with 1.61% Cu from 118m .

The footwall dacite hosted 2.2m of 1.77% Cu from 126m. The drill hole terminated at 133.3m in a silica-sericite-chlorite altered dacite with stringer pyrite.

(Note: intervals are reported as down-hole intersection widths)

Drill hole SSD094: (728800mE/7659670mN, Azimuth 000°/dip -78°) was drilled with an RC pre-collar through the hanging wall sequence to 89.9m. A HQ3 diamond tail completed the drill hole to 174.4m and intersected 53m of massive and semi-massive sulphide.

The assays for the semi-massive sulphide indicate four zones of zinc mineralisation with two zones of lead mineralisation with best results being:

  • 20m @ 12.05% Zn from 83m including

  • 9m @ 10.9% Zn and 2.24% Pb from 84m and

  • 4m @ 20.8% Zn and 2.67% Pb from 99m .

Beneath the initial high-grade intercepts, there are multiple zinc intercepts including:

  • 21.7m @ 1.5% Zn from 119m,

  • 11.5m @ 1.81% Zn from 143m and

  • 5m @ 1.59% Zn from 162m .

The drill hole terminated at 174.4m in a silica-sericite-chlorite altered dacite with stringer pyrite from 141m to the end-of-hole.

(Note: intervals are reported as down-hole intersection widths)

Drill hole SSD095: (728780mE/7659660mN, Azimuth 000°/dip -78°) was drilled with an RC pre-collar through the hanging wall sequence to 89.9m. The hole was completed with a combination of PQ3 and HQ3 diamond core to a depth of 138.6m. A total of 29.4m of massive and semi-massive pyrite was intersected from 89m with visible copper and zinc sulphides . From 118.4m to the end of the hole, disseminated to stockwork sulphide mineralisation with traces of chalcopyrite and sphalerite was intersected hosted in chlorite-altered dacite. Drill hole SSD095 is of particular interest as the observed sulphide intersection is wider than the existing interpretation in this part of the Resource – this may indicate potential for mineralisation to continue further to the west than initially envisaged .

Drill hole SSD096: (728780mE/7659660mN, Azimuth 000°/dip -70°) was drilled with an RC pre-collar through a weathered zone of gossanous dacite with disseminated pyrite from 82m to the end of the pre-collar at 87.8m. A diamond tail completed the drill hole at 174.5m. Massive and disseminated pyrite occurs from 87.8m to 97.6m. From 100.1 to 131.8m a further zone of massive sulphide was intersected; disseminated pyrite occasionally with chalcopyrite continued to the end of hole at 174.5 hosted in intensely chlorite/silica/sericite altered dacite.

Drill hole SSD097: (728780mE/7659660mN, Azimuth 014°/dip -64°) was drilled with an RC pre –collar through weathered dacite with fine grained massive sulphide from 90m to the end of the pre-collar at 92m. A PQ3 and HQ3 diamond tail completed the drill hole at 174.5m. From 91.8m to 97.6m a sequence of carbonaceous shales and dacite containing zones of massive and disseminated sulphide was encountered. Massive sulphide occurs from 100.1 to 131.8m and this is underlain by silica/chlorite/ sericite altered dacite containing disseminated to semi massive sulphide to the end of the drill hole.

Drill hole SSD098: (728780mE/7659660mN, Azimuth 037°/dip -68°) is currently in progress.

Management Comment

Venturex’s Executive Director Anthony Reilly said: “The results from hole SSD094 are of particular interest. While most of the holes to date have hit predominantly high-grade copper mineralisation, this is the first time we have encountered significant widths of high-grade zinc. The pending assay results and further geological review will help to establish if this is the start of a more significant zinc zone extending to the west, or a more localised event.

“The most recent holes, SSD095 and SSD096, have intersected significant widths of semi-massive to massive sulphide mineralisation, suggesting that the mineralisation may be laterally more extensive than originally thought potentially opening up new areas for exploration to the west”.

Section 1 Sampling Techniques and Data

Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling (e.g. 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.

In cases where ‘industry standard’ work has been done this would be relatively simple (e.g.
‘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.
Current Drilling
A combination of RC and Diamond drilling is being used to test the Sulphur Springs deposit.
The company uses industry standard practices to measure and mark up the drill core. Quarter
diamond core is to be submitted to the laboratory for analysis

Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka,
sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-
sampling bit or other type, whether core is oriented and if so, by what method, etc.).
Current Drilling
RC pre-collars followed by a combination of PQ3 and HQ3 diamond tail. All diamond core is stored
in industry standard core trays labelled with the drill hole ID and core interval.
Drill sample
recovery

Method of recording and assessing core and chip sample recoveries and results assessed.

Measures taken to maximise sample recovery and ensure representative nature of the samples.

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.
Current Drilling
Diamond core recoveries are recorded as a percentage of the measured core vs the drilling interval.
Core loss locations are recorded on core blocks by the drilling crew.
Diamond core was reconstructed into continuous runs where possible and metres checked against
the depth as recorded on core blocks by the drilling crew.
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.

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.)
photography.

The total length andpercentage of the relevant intersections logged.
Current Drilling
RC and Diamond drill core is geologically logged for the total length of the hole using a graphic
logging method. All core is photographed and images are stored in the company database. Logging
routinely recorded weathering, lithology, mineralogy, mineralization, structure, alteration and
veining. Logs are coded using the company geological coding legend and entered into the company
database.
Sub-sampling
techniques and
sample
preparation

If core, whether cut or sawn and whether quarter, half or all core taken.

If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.

For all sample types, the nature, quality and appropriateness of the sample preparation
technique.

Quality control procedures adopted for all sub-sampling stages to maximise representivity of
samples.

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.

Whether sample sizes are appropriate to thegrain size of the material being sampled.
Current Drilling
Drill core is cut by an automatic Almomte™ core saw and a quarter is sent for assay.
RC cuttings are split using a riffle splitter and the one metre samples from 10m interval above the
mineralised zone are individually submitted for assay. Four-metre composite samples are taken
using a PVC tube through the hangingwall sequence; the one metre composite samples returning
anomalous values will be submitted to elucidate the mineralisation.

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.

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.

Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external
laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision
have been established.
Current Drilling
The bulk density of the quarter drill core used for assay was determined by Venturex personnel on-
site using the wet and dry method.
Samples from the current drilling programme were assayed by Australian Laboratory Services Pty.
Ltd.
Composite and one metre RC samples and quarter core samples were prepared and analysed by
the following methods: Samples weighed, crushed and pulverised with the coarse residue retained
in vacuum seal bags. Cu, Pb, Zn, S, Fe and Ag analysed by method ME-OG62 and Au by fire assay
method Au-AA25.
The company included certified reference material and blanks with the samples submitted.
Verification of
sampling and
assaying

The verification of significant intersections by either independent or alternative company
personnel.

The use of twinned holes.

Documentation of primary data, data entry procedures, data verification, data storage
(physical and electronic) protocols.

Discuss any adjustment to assay data.
Current Drilling
The significant intersections reported have been prepared by geologists with relevant VMS
experience.
No twinned holes have been drilled.
The company uses standard templates created in Excel to collate sample intervals, drill collar,
downhole survey information which are emailed to the company main office were the information
is loaded into a database.
Geological descriptions are recorded in long hand prior to being summarised for digital data
capture.
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.

Specification of the grid system used.

Quality and adequacy of topographic control.
Current Drilling
Drill hole collars were located using a DGPS operated by company personnel.
Diamond drill holes are down-hole surveyed by a gyro every 30m.
Data spacing and
distribution

Data spacing for reporting of Exploration Results.

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.

Whether sample compositing has been applied.
Current Drilling
Drill holes are to be drilled on nominal 20m sections.
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.

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.
Current Drilling
Drill holes are designed to test the Sulphur Springs orebody which plunges at ~40-50 degrees to the
north. SSD089 was drilled vertically, SSD090 was drilled close to SSD089 and angled at-81˚ to the
south, SSD091 and SSD092 drilled 20m to the west with SSD091 angled at -81˚to the south and
SSD092 angled at -85˚to the north. SSD093 and SSD094 are drilled on section 728,800mE, 20 m
west of the section with SSD091 and 092. SSD095 and SSD096 are drilled on section 728,780. The
drill holes have been designed to test near surface potential of sulphide mineralisation amenable
to mining by open pit methods and are considered appropriate for the geometry of the deposit.
SSD097 is drilled on Section 728,780mE on an azimuth of 014˚ angled at -64˚. SSD098 is drilled on
section 728,780mE on an azimuth of 037˚ and angled at -68˚.

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.
Details of the drill holes are provided in Table 1 within the body of this report.
Data aggregation
methods

In reporting Exploration Results, weighting averaging techniques, maximum and/or
minimum grade truncations (e.g. cutting of high grades) and cut-off 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.
Results reported in this release for SSD095, SSD096 and SSD097 relate to visual observations of
drill core, specifically the identification of common sulphide minerals. No estimate of grade or
concentration of the minerals is provided.
Results reported for SSD093 and SSD094 were determined by ALS Laboratories using method ME-
OG 62 and fire assay Au-AA25.
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 (e.g. ‘down hole length, true width not known’).
The Sulphur Springs deposit plunges 40-50 degrees to the north; the drill holes are designed to
intersect the orebody at a nominal 60 degrees although the local access and topography require
certain holes to be designed taking these limitations into consideration to intersect the
mineralisation.
Only down hole intersections are reported.

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.
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.
The Sulphur Springs deposit has had a significant body of work completed on it, including
geophysical studies, metallurgical test work, geotechnical and ground water studies.
