-***-
--------------- ----------------------------------------------------------------
Criteria JORC Code explanation
--------------- ----------------------------------------------------------------
Sampling o Nature and quality of sampling (eg cut channels, random chips,
techniques 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.
o Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any
measurement tools or systems used.
o Aspects of the determination of mineralisation that are Material
to the Public Report.
o In cases where 'industry standard' work has been done this would
be relatively simple (eg '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 (eg submarine nodules) may warrant
disclosure of detailed information.

data in
relation of possible structures and the extent to which this is known,
to geological considering the deposit type.
structure

Criteria Commentary
------------- ------------------------------------------------------------------
Sampling o Three diamond drillholes (HQ3 collars and NQ3 tails) were
techniques completed by Techdrill Civil and Mining for TriAusMin Limited
(TRO).
o HQ3 and NQ3 diamond core were half cored using a brick style
diamond saw.
o Sample lengths ranged from 0.17 to 1.25 metres in length, with
the majority of sampled being 1.0 metre long. Sample splits were
determined by changes in geology.
o All samples were weighed by the laboratory and weights ranged
from 0.5 to 4.4 kilograms. Samples weighing over 3.2 kilograms
were riffle split by the laboratory.
------------- ------------------------------------------------------------------
Drilling o Diamond drilling was undertaken as HQ3 (61.1mm) and NQ3 (45.1mm)
techniques diameter core. A total of 81.7 metres of HQ3 core and 471.9
metres of NQ3 core were drilled. Chrome barrels were used at all
times. A Global Tech core orientation device was used for all
NQ3 drilling to enable core orienting to be conducted. No
orientation device was used for HQ3 drilling.
------------- ------------------------------------------------------------------
Drill sample o Triple tube was used at all times to maximize core recovery and
recovery ensure integrity of the material structure.
o Core recovery was measured on all core with recoveries generally
being in excess of 95%, except at the start of holes in soil -
saprolite zone the top 2 to 3 metres) where core loss occurred.
------------- ------------------------------------------------------------------
Logging o Geological and geotechnical logging was completed by a
professional geologist using TROs logging procedures that were
developed to accurately cover the local geology and
mineralization. These include: geology (including lithology,
mineralization and alteration), structure, fracture frequency,
core recovery and RQD.
o All drill core was logged quantitatively and all drill core was
photographed (wet only).
------------- ------------------------------------------------------------------
Sub-sampling o All core samples were of half core cut with a brick style
techniques
and diamond saw.
sample
preparation o No sub-sampling was done.
o All samples were sent to an accredited laboratory for sample
preparation and analysis. ALS Global follow industry best
standards in sample preparation including drying, crushing and
pulverizing the entire sample to a grind size of 85% passing at
75 microns. Samples over 3.2 kilograms were riffle-split
o Sample sizes are more than adequate to correctly represent the
style and nature of the copper mineralization.
------------- ------------------------------------------------------------------
Quality of
assay o Gold is analysed by fire-assay fusion (method Au-AA-25
data and which is a 30 gram charge) that is considered a total
laboratory
tests method. Thirty-five base metals and other pathfinder
elements are determined by methods ME-ICP41 (and for
over-range samples OG46) which uses an aqua-regia digest
followed by an ICPAES analysis. This is considered a
partial digest.
o No geophysical tools nor XRF instruments were used.
o TRO inserted 16 certified OREAS standards (some of which
are siltstone blanks) into the single batch with 298 half
core samples. The insertion rate was nominally one
standard per 24 normal standards. No duplicates were
submitted. ALS laboratories conduct their own stringent
internal QA-QC protocols as part of their own internal
standard procedures which includes the use of fusion
duplicates, blanks and certified reference materials.
------------- ------------------------------------------------------------------
Verification
of o None were undertaken in this program.
sampling and
assaying o No holes were twinned in this program.
o All drillhole data was captured in individual excel spreadsheets
that were visually checked, then later validated using GIS /
drilling software, and at that time any errors were corrected.
o No assay data was adjusted. Samples over-range in copper and
zinc were re-assayed by ore-grade method OG-46 method.
------------- ------------------------------------------------------------------
Location
of data o Drillhole collars were located by a professional surveyor using
points a DGPS with precision of 10 to 20 centimetres. All other surface
mapping and sampling done on this prospect was done using a
Garmin handheld GPS 60CSx with an accuracy of 5 metres. Downhole
surveys were done at a nominal spacing of 30 metres (downhole)
using a Camteq Multi-shot instrument.
o Grid system used for Lewis Ponds regional work is GDA94 MGA Zone
55 and RL is AHD.
o Topographic control was assessed by DGPS in AHD.
------------- ------------------------------------------------------------------
Data spacing
and o Drillhole locations are stated in Table 1. The holes were
distribution designed as a first pass test of a 400 metre long modelled EM
plate with holes spaced roughly 100 metres apart along strike.
The drill program was a first pass drilling assessment and it
clearly is not close enough to establish any kind of resource.
o No sample compositing was necessary nor applied.
------------- ------------------------------------------------------------------
Orientation
of o All drillholes were aligned orthogonally to the strike of the
data in
relation targeted plate and the mapped geology. Two of the 3 holes were
to geological drilled as close to 90(degree) to the dip of the target. MNDD004
structure was drilled as shallowly as safely possible (-55(degree)) from
the footwall intersecting the veins in a down-dip orientation.
------------- ------------------------------------------------------------------
Sample
security o All samples were placed into individual calico bags and each
calico bag into a pollyweave bag. Each pollyweave bag was closed
with a secure plastic zippy-tie. All samples were delivered
directly to the laboratory in Orange by company employees to
ensure sample security.
------------- ------------------------------------------------------------------
Audits or o No audits or reviews have been completed.

Drill hole oA summary of all information material to the understanding of
Information the exploration results including a tabulation of the following
information for all Material drill holes:
o easting and northing of the drill hole collar
o elevation or RL (Reduced Level - elevation above sea level in
metres) of the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
oIf 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 oIn reporting Exploration Results, weighting averaging
methods techniques, maximum and/or minimum grade truncations (eg cutting
of high grades) and cut-off grades are usually Material and
should be stated.
oWhere 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.
oThe assumptions used for any reporting of metal equivalent
values should be clearly stated.
-------------- -----------------------------------------------------------------
Relationship oThese relationships are particularly important in the reporting
between of Exploration Results.
mineralisation
widths and oIf the geometry of the mineralisation with respect to the drill
intercept hole angle is known, its nature should be reported.

oIf it is not known and only the down hole lengths are reported,
there should be a clear statement to this effect (eg 'down hole
length, true width not known').
-------------- -----------------------------------------------------------------
Diagrams oAppropriate 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.
