Australian Securities Exchange Announcement

28 July 2014

ASX Market Announcements Australian Securities Exchange 20 Bridge Street SYDNEY NSW 2000

Spargoville Air Core Resample Results

  • 10m @ 2.39g/t Au from 48m including 1m @ 11.3g/t from 55m
  • 2m @ 25.8g/t Au from 34m including 1m @ 46.9g/t Au from 35m
  • 5m @ 6.78g/t Au from 45m including 1m @ 27.0g/t Au from 47m
  • RC Drilling programme to test the results now in progress

Tychean Resources Ltd (ASX: TYK) (Tychean or Company) is pleased to announce that one metre resampling results of significant (≥0.5g/t Au) composite results from the Air Core drilling completed in May 2014 has confirmed highly anomalous gold intercepts. The drilling was completed both to the East and South of the Golden Orb Prospect (Figure 1), at the Company's wholly owned Spargoville Gold Project in the Eastern Goldfields of Western Australia.

A total of 32 one metre scoop samples were collected from significant (≥0.5g/t Au) composite samples1 returned from the Air Core drilling completed during May 2014.

All significant (≥0.5g/t Au) intercepts from the drilling were received within weathered ultramafic lithologies at or adjacent to contacts with felsic lithologies. As well as confirming the significant intercepts returned from the initial composite sampling, the sampling has highlighted a high grade component to the intercepts, a characteristic of the high grade Wattle Dam mineralisation.

Updated significant (≥0.5g/t Au) results from the air core drilling are included in Table 1 and all collar details from the completed drilling are included in Table 2.

RC drilling designed to further evaluate the returned intercepts has commenced2 and is expected to be completed by mid-August.

Section 1: Sampling Techniques & 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.
Single metre scoop samples over significant intervals
highlighted from previous composite sampling were collected
from air core drill holes which were drilled to infill interpreted
mineralised trends identified from previous drilling to a drill
spacing of 20m x 50m.
A total of 20 Air Core drill holes for
1,213 metres were completed.
Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any
measurement tools or systems used.
A consistent scoop sampling method has been adopted for
composite RAB and Air Core drilling.
All sampling protocols
remained constant throughout the program.
All drill hole
locations were determined by handheld GPS.
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.
Air Core drilling was used to obtain one metre drill samples
from which approximately a 2-3 kg composite sample (scoop
sampled as per above) was pulverized (>90% smaller than 75
micron) to produce a pulp sample for analysis.
Analysis of the four metre composite samples comprised a
25g aqua regia digest, solvent extraction then Flame Atomic
Absorption Spectrometry for Au determination to a lower
detection limit of 0.01ppm Au.
Significant intervals returned
from the composite results were later collected and submitted
by analysis via a 25g charge aqua regia digest followed by
Atomic Absorption Spectrometry finish.
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.).
All drilling was completed via Air Core Drilling.
All holes were
completed to blade refusal for an average depth of
approximately 61 metres.
Drill sample
recovery
Method of recording and assessing core and chip sample
recoveries and results assessed.
No recording of recoveries was undertaken.
Measures taken to maximise sample recovery and ensure
representative nature of the samples.
Drill cyclone and sample buckets are cleaned when required
during each drill hole and after each hole to minimise down
hole and/or cross contamination.
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 relationship has been identified to date.
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.
The use of scoop sampled Air Core drilling results is not
appropriate for mineral resource estimate and is considered a
qualitative sampling technique.
Whether logging is qualitative or quantitative in nature. Core
(or costean, channel, etc.) photography.
Logging of Air Core drill chips recorded lithology, weathering,
veining, mineralisation, and other features of the drill samples.
A EOH chip sample reference was collected for each hole.
The total length and percentage of the relevant intersections
logged.
All drill holes were logged in full from start to end of hole.
Sub
sampling
If core, whether cut or sawn and whether quarter, half or all
core taken.
No core.
techniques
and sample
preparation
If non-core, whether riffled, tube sampled, rotary split, etc. and
whether sampled wet or dry.
The drilling comprised dry samples which were scoop sampled
over 4 consecutive metres and one metre samples (where
applicable).
For all sample types, the nature, quality and appropriateness
of the sample preparation technique.
The sample preparation of the Air Core chip samples follows
industry best practice in sample preparation involving oven
drying, crushing and pulverising of the total sample (total prep)
so that a minimum of 90% of pulverized material is less than
75µm grind size.
Quality control procedures adopted for all sub-sampling
stages to maximise representivity of samples.
The laboratory conducted up to one repeat analysis on all
composite samples returning >0.1ppm Au and conducted
routine

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.
No duplicate sampling was completed.
All samples were
collected to weigh less than 3kg to ensure the entire sample is
pulverized prior to subsampling for digesting.
Whether sample sizes are appropriate to the grain size of the
material being sampled.
Given the qualitative nature of the sampling technique, the
sample sizes are considered appropriate to give an indication
of degree and extent of anomalism.
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.
The aqua regia digest is considered a near total digest and is
considered appropriate considering the nature of sample
collected.
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.
None used
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.
The laboratory conducted up to one repeat analysis on all
composite samples returning >0.1ppm Au and conducted
routine 1 in 20 check analysis and regular blank and
mineralized standard analyses throughout.
The laboratory
conducted two repeat analysis on the single metre samples
which comprised the two highest returned assays and
conducted routine 1 in 20 check analysis and regular blank
and mineralized standard analyses throughout. From these
results it has been determined that an acceptable level of
accuracy and precision has been achieved.
Verification
of sampling
The verification of significant intersections by either
independent or alternative company personnel.
None undertaken.
and
assaying
The use of twinned holes. None undertaken.
Documentation of primary data, data entry procedures, data
verification, data storage (physical and electronic) protocols.
Field and laboratory data have been collected electronically.
The electronic data has been validated visually and
automatically using Micromine software.
Discuss any adjustment to assay data. None undertaken.
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.
The location of drill hole collars was determined by handheld
GPS prior to drilling which is expected to have an accuracy of
+/- 5m.
The level of accuracy of the collar location details is
considered appropriate for the nature of drilling completed.
Specification of the grid system used. The coordinate system in use was GDA1994 MGA Zone 51.
Quality and adequacy of topographic control. A nominal RL of 340m has been used for the drilling.
Data Data spacing for reporting of Exploration Results. The majority of drilling ensured drill coverage of 20m x 50m.
spacing and
distribution
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.
At this stage no mineral resource or reserve estimates have
been undertaken.
Collected samples and subsequent results
from the RAB drilling are not suitable for incorporation into
mineral resource or ore reserve estimations.
Whether sample compositing has been applied. The original four metre composites were collected from the
drill samples in the field.
Orientation
of data in
relation to
Whether the orientation of sampling achieves unbiased
sampling of possible structures and the extent to which this is
known, considering the deposit type.
The completed drilling was undertaken roughly perpendicular
to the strike direction of the geology and related
mineralisation.
geological
structure
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.
No orientation based sampling bias has been identified in the
data
Sample
security
The measures taken to ensure sample security. All one metre samples were immediately delivered to
Genalysis Laboratories in Kalgoorlie for sample preparation.
After sample preparation, a representative pulp sample was
sent down the Perth laboratory for analysis.

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.
Air Core drill hole locations are depicted on the included
figures within the body of text and a full list of hole collar
details are included as Table 2.
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 information has been excluded
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.
When reporting exploration results an average of the Au and
available Au repeat results which are ≥0.5g/t Au, are
averaged and reported. When consecutive down hole
samples returned >0.5ppm, the weighted average gold
values for each relevant interval is used to obtain an intercept
average.
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
Any aggregate results which are biased by one or more
higher grade single composite results, then these composite
results are detailed.
values should be clearly stated. No metal equivalents reported.
Relationship
between
mineralisation
widths and
intercept
lengths
These relationships are particularly important in the reporting
of Exploration Results.
Not enough information is known about the nature and
orientation of the mineralisation within the area at this stage.
If the mineralisation is vertical then the downhole width of the
intercepted mineralisation would be twice that of the true
width, as was the Case at Wattle Dam Gold Mine.
If the geometry of the mineralisation with respect to the drill
hole angle is known, its nature should be reported.
The orientation of the mineralisation is unknown. Further
drilling including air core, RC and diamond drilling will be
required to determine the orientation of mineralisation.
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 reported intercepts are down hole lengths only as the
true width of is not known.
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.
