Venturex Resources Limited (ASX: VXR "Venturex" and the "Company") is pleased to advise that it has completed the initial phase of diamond drilling at its 100%-owned Whim Creek Zinc-Copper Project , located 115km south-west of Port Hedland in Western Australia. The Whim Creek Project includes the Whim Creek, Mons Cupri, Salt Creek and Evelyn deposits plus 18,500 hectares of tenements covering the highly prospective Whim Creek basin.
Mons Cupri
The Company completed four diamond drill holes to test high priority IP chargeability anomalies identified in the recent high powered IP survey undertaken in the immediate vicinity of the Mons Cupri deposit (see ASX release 4 July 2016).
These IP chargeability anomalies are believed to be related to stock-work zones of pyrite and chalcopyrite mineralisation in the Cistern Formation conglomerate, which is the host for the economic mineralisation at the Mons Cupri deposit.
==> picture [156 x 52] intentionally omitted <==
These stock-work zones represent potential feeder zones for the high grade massive sulphide zinclead-silver mineralisation and the underlying high grade stringer sulphide copper-gold mineralisation found in the Mons Cupri deposit.
The Company’s exploration strategy has been to first identify zones of IP chargeability and then drill them to confirm the presence of sulphide mineralisation and alteration. Where sulphides and alteration have been intersected, the holes will be used as a platform for DHMMR which will provide a potential vector towards any high grade massive sulphide zinc-lead-silver mineralisation.
Previous petro-physical test work on high grade massive sulphide core from the Mons Cupri deposit has indicated that DHMMR is more effective for low conductivity/poorly conductive massive zinc sulphide-rich mineralisation than the traditional transient electromagnetic (TEM) methods.
Diamond drill-hole 16VMCD001 was designed to test an IP chargeability anomaly extending downdip of the Mons Cupri NW open pit which may represent an extension of the mineralisation in the pit. This hole deviated away from the IP anomaly and was terminated early. However, the hole did intersect 2.1 metres of strong sericite, carbonate, silica, pyrite altered Cistern Formation conglomerate at the expected target depth, just below the contact with the overlying Rushall Formation shale.
Diamond drill-hole 16VMCD002 was designed to test an IP chargeability anomaly that extends downdip of the main Mons Cupri open pit which may represent an extension of the mineralisation in the pit. The hole intersected three zones of alteration. The upper zone of sericite pyrite alteration is in the mudstones siltstones and sandstones of the Rushall Formation just above the contact with the underlying Cistern Formation conglomerate.
The second alteration zone is 8.5m thick and occurs in the conglomerate immediately below the contact. This is variable weak to intense sericite-chlorite-pyrite alteration with visual mineralisation of pyrite and chalcopyrite present in a narrow zone at the Cistern Formation contact.
A third, deeper 5.6 m thick alteration zone was identified from 164m hosted in shale and sandstone approximately 50m below Cistern Formation contact. This strong alteration occurs at a similar stratigraphic position to the high grade massive sulphide zinc-lead-silver zones in the Mons Cupri deposit.
The location of the drill-holes is shown in Figure 1 and details of the holes are shown in Table 1.
This drilling has demonstrated that the right conditions are present for the development of mineralisation. The next step is to carry out DHMMR surveys on these holes.
Salt Creek
Diamond Drilling
Venturex has completed six diamond drill holes at the Salt Creek deposit. The pierce points of these holes are shown in Figure 2 and details provided in Table 2 .
The objective of these holes was to target near-surface extensions of the high grade zinc-lead-silver lodes at Salt Creek that may be amenable to open cut mining. Visual results of the high grade mineralisation intersected in holes 16VSCD001 and 16VSD003 have already been released (see ASX release 19 September 2016).

==> picture [156 x 52] intentionally omitted <==
Holes 16VSCD004-006 were drilled at the margins of the Salt Creek Resource. Two of these holes intersected moderate to strong sericite alteration as well as visible pyrite, sphalerite and galena mineralisation consistent with being at the margin of a high grade massive sulphide lode.
These holes have been cased for follow-up by DHMMR surveys to identify the potential for additional high grade mineralisation nearby.
Processing of Down-hole Geophysical Data from Salt Creek
The Company recently identified an historical suite of geophysical data consisting of eight TEM and 25 DHMMR surveys completed in 2008 from drill holes in the Salt Creek deposit. This data had not previously been processed/interpreted.
The Company’s Consultant Geophysicist, Russell Mortimer, of Southern Geoscience Consultants Pty Ltd, has processed/interpreted these datasets. The results have confirmed the effectiveness of the DHMMR technique for the definition of low conductivity targets associated with massive zinc and lead sulphide mineralisation and the traditional TEM technique to detect more conductive chalcopyrite sulphide mineralisation at Salt Creek.
The results of the surveys are shown in long section Figure 2 .
A number of well resolved DHMMR plate conductors (dark green) have been modelled within and adjacent to the existing Resource outline that could indicate potential extensions of the high grade massive zinc-lead-silver lodes that warrant further drilling.
Less well resolved down hole DHTEM and DHMMR targets that represent potential down-plunge extensions to the known high grade zinc and copper mineralisation have also been identified.
Current Work Program
Samples from the drilling program have been progressively processed and submitted to the laboratory. First results are expected in the next few weeks.
A geophysical survey crew is being mobilised to carry out additional DHMMR surveys on a selection of the drill holes recently completed at Mons Cupri and Salt Creek.
A specialist Structural Geologist has been engaged to log relevant drill holes at Salt Creek to develop a structural model of the controls for the mineralisation within the deposit. This will be combined with the latest geological model and the geophysical targets to provide a framework for planning the next drill program to test for extensions to the Salt Creek Resource.
This survey and modelling work will be completed by the end of October 2016 with the expectation that further targets at both Mons Cupri and Salt Creek will be developed for drilling to recommence in November 2016 subject to drill rig availability.
Management Comment
Venturex’s Managing Director, Mr John Nitschke, said the initial phase of drilling at Whim Creek had confirmed the validity of the Company’s exploration approach and provided a clear forward direction for the next phase of exploration which would commence during October.

==> picture [156 x 52] intentionally omitted <==
“The first phase of the program included some aggressive step-outs from the known Resources at both the Mons Cupri and Salt Creek deposits,” he said.
“While we have yet to receive assay results, geological logging of the core indicates that we intersected alteration some 500m to the west of the Mons Cupri resource, confirming the presence of mineralising events in the main geological host horizon in a location well beyond the known Resource.
“This is a highly encouraging development, which clearly highlights how fertile this VMS field is for the potential discovery of repeats of the known orebodies. Considering that Mons Cupri was a very significant VMS deposit with a pre-mining Resource of 10 million tonnes, this is an exciting and significant development.
“Having identified the alteration zone in the host rocks we are now looking for any high grade massive zinc sulphides that may be offset from the drill intersections using state-of-the-art highpowered down hole MMR equipment. This method is far superior to any geophysical method that has been used at Mons Cupri historically.
“We are also fortunate to have found the misplaced historic datasets from Salt Creek. This has yielded several exciting new targets, and gives us the opportunity to identify plenty of walk-up drill targets with the potential to extend the Resource.
“The next key phase of down hole MMR geophysics will be underway this week and we expect to be back drilling again in November,” Mr Nitschke said.

About Venturex Resources Limited
Venturex Resources (ASX: VXR) is a rapidly growing Australian zinc company which is focused on the exploration and development of its two advanced zinccopper projects located near Port Hedland in the premier Pilbara mining province of Western Australia. After recently completing a $5 million capital raising, Venturex has embarked on a major new drilling program aimed at further expanding its resource inventory, which comprises more than 900,000t of contained zinc and 320,000t of contained copper.
6
==> picture [156 x 52] intentionally omitted <==
Its initial exploration focus is on extending the existing high-grade zinc, copper and lead resources at the Whim Creek Project, where it has identified a range of targets adjacent to the Salt Creek and Mons Cupri deposits. Drilling commenced in late August and will continue through until the end of the year, generating strong ongoing news-flow. The successful extension of the known Resources at Whim Creek will result in a project that is compelling at spot prices. The existing infrastructure at Whim Creek means that any such project could be producing zinc, copper and lead concentrates during the first half of calendar 2018.
Venturex is continuing to progress permitting and pre-development activities for its Sulphur Springs Project, one of the most significant undeveloped zinc deposits in Australia. On-going value engineering of the 2013 Feasibility Study has resulted in a potential low-risk copper-zinc project with attractive economics and a proposed low-CAPEX Stage 1 development based on a near-surface high grade supergene copper zone.
Venturex also receives an ongoing income stream from a profit share in an SX/EW heap leach operation recovering copper from the heap leach dumps at Whim Creek. Venturex received $780,000 in FY2016 from 990,000t of copper metal production. This cash flow covers the bulk of the Company’s overheads and is expected to continue for the next 2-3 years.
About Zinc
Zinc is a blue-grey metal which readily forms alloys with metals including copper, aluminium and magnesium. Zinc is primarily used for its corrosion resistance in galvanising which accounts for approximately half of global zinc consumption. Galvanised materials (commonly iron and steel) are used extensively in transport, construction and appliance manufacturing purposes. Metallic zinc is also used in dry cell batteries, die-casting, roof cladding and in the production of zinc oxide.
Zinc demand is dominated by China at 6.9Mt or 49%. Global consumption is forecast to grow at a CAGR of 2% over 2016-2020, with the strongest demand growth coming from China at 2% and also the US and India. Following recent mine closures and this increasing demand growth, the current zinc market is tight with declining global inventories and a supply deficit forecast in coming years. Zinc prices have responded accordingly rallying above the top of the global mine cost curve. The concentrate market also reflects this supply tightness, with smelters materially discounting treatment charges.

(Criteria listed in the preceding section also apply to this section.)
Criteria JORC Code Explanation
Commentary
-
Sampling Nature and quality of sampling (e.g. cut channels, random chips, or specific techniques 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.

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 the grain size of the material being sampled. |
RC drilling:1 metre samples were collected and split off the drill rig using a cone splitter. The samples were generally dry and of a consistent size. Logged mineralized zones were sub split using a riffle splitter to give a 4m composite sample suitable for assaying. Venturex had on site, technically competent supervision and procedures in place to ensure sample preparation integrity and quality. The sample sizes are considered appropriate given the relatively fine grained nature of the sulphide mineralisation which is not nuggetty in nature, the sampling methodology and the range of the anticipated t assay value. Diamond core was cut in half. All samples were from the same side of the core. No field duplicates were collected The sample size is considered appropriate for the base metal – volcanic massive sulphide mineralisation style. |

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. |
The collar positions of holes were surveyed by DGPS using MGA94 zone 50 coordinates. The down-hole surveys were completed with a single shot reflex tool every 30m down hole. For ground geophysical surveys the loop positions and stations were located by hand held GPS |
| 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. |
Drill hole spacing at Salt Creek is a nominal 20m x 20m. The Mons Cupri drilling is targeting specific IP conductors therefore drill spacing is non applicable. 4m composite samples were collected through mineralized or altered zones in the RC and pre-collar holes. Diamond core was sampled to geological contacts on nominal 1m intervals. |
| 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. |
The survey layouts were orientated perpendicular to the strike of the geology and mineralisation All the drilling was orientated to intersect the target perpendicularly. At Salt Creek the diamond holes were orientated at -60 degrees toward 330 degrees. The drilling at Mons Cupri was orientated to intersect the strongest part of the IP anomaly. |
| Sample security |
The measures taken to ensure sample security. |
Samples are stored on site and transported to the Perth laboratory by truck. Samples are then stored in the lock yard at the laboratory. The digital data has been stored in the archives of the company’s consultant physicist Southern Geoscience Consultants |

| Geology | Deposit type, geological setting and style of mineralisation. |
The Mons Cupri and Salt Creek Deposits are located with the Archaean aged Whim Creek Basin, a sequence of intermediate to felsic volcanic, volcanoclastic and sediments. The deposits are classed as a volcanogenic massive sulphide (VMS). Massive sulphide and stringer sulphide mineralisation has been deposited at the top of the Cistern Formation which comprises a thick sequence of volcanogenic siltstone, sandstone & conglomerate with minor shale units. The Cistern Formation is overlain bythe Rushall Formation. |

| 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. |

| 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. |
Not applicable |
| 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’). _ |
Not applicable |
| 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. |

| 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 Salt Creek Deposit has had a significant body of work completed on it, including geophysical studies, metallurgical test work geotechnical and ground water studies. |
| Further work | The nature and scale of planned further work (e.g. 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 |
The geophysical review has generated a number of subsurface targets which will be reviewed |
