First Pass Exploration Identifies a Copper/Lead/Silver System with Rock Chips Assaying up to 296g/t Silver
Thali Prospect - Thailand
ASX Announcement
Tuesday 8 September 2015
Ref: /VMS/606/VMS0355
Venture Minerals Limited (ASX code: VMS), is pleased to announce that first pass exploration on the recently granted Thali Prospect in northern Thailand (refer Figure One) has already delivered some excellent, high grade results from initial rock chip sampling including:
(Refer to full table of results Appendix One)
The presence of significant lead grades and high silver grades suggests Thali may host a substantial mineralized system potentially epithermal in nature. Initial reconnaissance work has identified mineralization over 300m of strike (Refer Figure Two) however, on-going work will focus on extending the known zone along strike.
Having only very recently received our first granted tenure in Thailand the Company is very pleased to have already identified significant and high grade mineralization at surface from reconnaissance style exploration.
Further detailed geological mapping and surface sampling will continue over the coming weeks, with results expected shortly thereafter.

Thali Prospect - Geology
Exposure in the Thali prospect area is sparse and largely restricted to saprolite and saprock after felsic volcanic rocks, tuffaceous sedimentary rocks and sericite-altered granitoid with stockworks of partly oxidised sulphide and quartz veinlets. Reconnaissance prospecting has identified a north trending zone at least 300 m long of gossanous quartz veins and breccias with boxworks of secondary minerals after iron and base metal sulphides (Refer Figure Two). Regional scale geological mapping suggests the host volcanic rocks are of Permian-Triassic age, and the granitic intrusions Triassic age; the Triassic granitoid suite is widely associated with base and precious metal deposits within the Loei Belt.

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.
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.
|
Rock samples were collected from visibly mineralized outcrop and sub-crop by Venture Minerals Ltd
geologists.
Each rock sample weighed between 1 and 3 kg and was of sufficient size to be representative of the outcrop of
interest.
|
Drilling techniques
|
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..).
|
No drilling, not applicable
|
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.
|
No drilling, not applicable
|
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 and percentage of the relevant intersections logged.
|
The rock samples were qualitatively logged and described by a suitably qualified geologist.
|
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 the grain size of the material being sampled.
|
The rock samples were dispatched to commercial assay laboratories Mineral and Assay Services Co Ltd, Bangkok
("MAS") or ALS Global, Perth ("ALS") for preparation and
assay.
Rock samples submitted to MAS were oven dried then entirely crushed to 100 % passing 2 mm, then 500 g was
split off each sample and pulverized to nominally 90 %
passing 74 microns to produce the analytical pulps.
Rock samples submitted to ALS were each crushed 70%
passing 6 mm then entirely pulverized to nominally 80%
passing 75 microns to produce the analytical pulps.
No drilling so information regarding drill sampling not applicable.
|
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.
|
At MAS the analytical pulps were subjected to industry standard four acid digest (perchloric, nitric, hydrofluoric
and hydrochloric) followed by Inductively Coupled
Plasma Emission Spectrometry (ICP-ES) finish to read Cu, Ag, Pb and Zn. Samples with above 1% Pb were re- assayed by sodium peroxide fusion followed by acid
digest and Atomic Absorption Spectrometry finish.
At ALS the analytical pulps were assayed by industry standard four acid digest (perchloric, nitric, hydrofluoric
and hydrochloric) followed by ICP-ES finish to read Cu,
Ag, Pb and Zn.

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.
|
The assay results agree well with the observed minerals and weathering textures in the rock samples.
The use of twinned holes is not applicable at this stage
(no drilling).
Primary data is stored and documented in industry standard ways.
The assay data is as reported by MAS or ALS and has not been adjusted in any way.
Remnant assay pulps are held in storage by Venture
Minerals Ltd.
|
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.
|
Rock sample locations were determined by handheld
Garmin GPS considered accurate to ±10 m and verified by plotting on Thai government 1:50,000 topographic
maps.
All co-ordinates were recorded in UTM Zone 47N
datum WGS84.
Topographic control is provided by Thai government
1:50,000 topographic map sheets and a Digital Terrain Model based on the 90 m Shuttle Radar Topographic Mission data.
|
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.
|
Only visibly mineralized rocks were sampled for assay and sampling is of a reconnaissance nature. Sample
following an identified gossanous vein and breccia
trend, and was principally limited by available outcrop and sub-crop.
The reported rock sampling data is in no way sufficient to establish mineral resources.
Sample compositing has not been applied.
|
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 reconnaissance rock sampling defines a North trending zone of Cu-Pb-Ag mineralization.
No drilling, not applicable.
|
Sample security
|
The measures taken to ensure sample security.
|
The chain of custody for all Venture samples from collection to dispatch to MAS for assay is managed by
Venture personnel. Sample numbers are unique and do
not include any locational information useful to non- Venture personnel. The level of security is considered appropriate for reconnaissance surface rock sampling.
|
Audits or reviews
|
The results of any audits or reviews of sampling techniques and data.
|
The assay results agree well with the observed amount of Cu and Pb minerals in the rock samples.
No further reviews have been carried out at this reconnaissance stage.
Further surface sampling to verify these reconnaissance results is proposed.

Commentary
|
Mineral tenement and land tenure status
|
Type, reference name/number, location and ownership including agreements or material issues with third parties such
as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
The security of the tenure held at the time of reporting along
with any known impediments to obtaining a licence to operate in the area.
|
The exploration targets are located within Special
Prospecting License 70/2558.
The exploration tenements are 100% held by Venture Minerals Thailand Ltd, a wholly owned subsidiary of Venture Minerals Ltd, and there are no encumbrances or non-standard regulations.
The Special Prospecting Licences allow all industry standard stages of mineral exploration, resource and
reserve definition.
|
Exploration done by other parties
|
Acknowledgment and appraisal of exploration by other parties.
|
Previous exploration work has included regional stream sediment sampling and airborne magnetic
surveying by the Department of Mineral Resources of
Thailand. To Venture Minerals knowledge there has been no previous local scale exploration of the target
area.
|
Geology
|
Deposit type, geological setting and style of mineralisation.
|
The exploration area is within the Loei Belt and considered prospective for base and precious metal
skarn, porphyry and epithermal deposits. Nearby
deposits of this style include PanAust's operating Phu
Kham and Ban Houayxai mines in Laos.
|
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.
|
No drilling, not applicable.
|
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.
|
No drilling, not applicable.

Commentary
|
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').
|
No drilling, 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.
|
An appropriate exploration plan is included in the body of this release, including location of the
mineralized rock samples.
No drilling, so drill plans and sections are not applicable.
|
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.
|
Not applicable at this reconnaissance stage.
|
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.
|
Appropriate reconnaissance exploration plans are included in the body of this release.
|
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.
|
Venture proposes to conduct further prospecting and geochemical sampling to refine the targets before drill
testing.
An appropriate exploration target plan is included in the body of this release.
