Additional High Grade Silver/Zinc/Lead Targets Discovered at Thali - Loei Belt, Thailand
ASX Announcement Friday, 29 July 2016
Ref: /VMS/606/VMS0387
Venture Minerals Limited (ASX code: VMS), is pleased to announce that on-going soil sampling at the Company's Thali Project continues to deliver new high grade silver/zinc/lead targets. During the past three months Venture has substantially increased its priority targets, which now covers over 260 hectares. These latest discoveries deliver the Company "walk-up" drill targets which extend over a combined strike of over 7.5km (Refer Figure One).
In addition to the latest discoveries at Thali Far East, the Company has also been focussing its exploration on the northern extension of the intrusive complex. Detailed mapping in this area continues to identify gossan and skarn mineralization associated with a significant limestone/sandstone unit that extends over at least 10km of strike.
Thali Project | Recent Exploration Highlights:
-
Thali contains six prospects hosting high tenor base and precious metal soil anomalies covering a combined area of over 260 hectares
-
Surface sampling and geological mapping has defined silver/zinc/lead systems extending over a combined strike of over 7.5km
-
Rock chip sampling has delivered high grade silver and lead results at surface, including
1,860g/t Ag & 27% Pb
-
Consistent high grade soil anomalies exist over all six prospects peaking at 4,600ppb silver, 4,170ppm zinc & 1,565ppm lead
Venture has now finalised its drill program, which includes a combination of RC and diamond drilling targeting the majority of high grade soil anomalies. Approval from local authorities for the drill program is currently being finalised.

Thali Project | Geology
Venture's geological mapping of the new Thali base metal prospects shows the area is underlain by a mainly north striking sequence of sedimentary rocks, including limestone, intruded by a series of intermediate to felsic porphyries, diorite and granite. The observed base and precious metal mineralisation is associated with gossanous veins and stockwork zones in sericite, silica and sulphide altered igneous rocks (mainly Thali North and Thali South), and with stockwork veined and sulphide-bearing calc-silicate skarn within the sedimentary host rocks (especially Thali East and North-East). Regional scale geological mapping suggests the host sedimentary rocks are of Permian-Triassic age, and the granitic intrusions of Triassic age; the Triassic granitoid suite is widely associated with base and precious metal deposits within the Loei Belt.

The information in this report that relates to Exploration Results and Exploration Targets is based on information compiled by Mr Andrew Radonjic, a full time employee of the company and who is a Member of The Australasian Institute of Mining and Metallurgy. Mr Andrew Radonjic has sufficient experience which is relevant to the style of mineralisation and type of deposits under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves'. Mr Andrew Radonjic consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.

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.
|
-
Soil samples were collected by Venture Minerals Ltd personnel. The sampling team comprised one geologist and up to three field assistants.
-
Soil samples were collected using hand tools (mattock and shovel) from the B horizon at depths ranging from 20 to 45cm.
-
Each soil sample weighed between 1 and 3 kg when collected, A field duplicate was collected every c. 20th sample site.
-
After collection the soil samples were air dried and screened to -2mm.
|
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..).
|
|
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.
|
|
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.
|
|
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.
|
-
After drying and screening to c. -2mm the soil samples were subsampled by repeated passes through a 50:50 riffle splitter to produce c. 200g split for assay.
-
The 200g splits were all analysed for Cu, Pb and Zn by Venture Minerals Ltd personnel using Olympus Delta 50 Premium portable XRF. The 200g splits were then submitted to commercial assay laboratory ALS Global, Perth ("ALS") for assay of Ag. At ALS the entire 200g splits were pulverised 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
|
-
At ALS the analytical pulps were assayed by industry standard four acid digest (perchloric, nitric, hydrofluoric and hydrochloric) followed by ICP-OES and ICP-MS finish to read Cu, Ag, Pb and Zn.
-
Commercially certified Ag and base metal reference materials were included in both portable XRF and ALS batches at a minimum rate of one standard per 30 soil samples.
-
Approx. 8% of the Cu and Zn assays and 24% of the Pb assays obtained by portable XRF were verified by
