Sampling techniques

Nature and quality of sampling (eg 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.

Sampling is by sawn half core HQ & NQ core or quarter PQ core. Nominal sample intervals are

1m with a range from 0.5m to 1.5m.

Samples are transported to ALS Chemex Orange for preparation and assay

Sampling techniques

Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

Assay standards or blanks are inserted at least every 40 samples. Silica flush samples are employed after each occurrence of visible gold.

During resource drill out programmes duplicate splits of the coarse reject fraction of the crushed core are assayed every 20 samples.

Sampling techniques

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 (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.

Diamond drilling was used to obtain core samples of nominally 1m, but with a range between

0.5-1.5m. Core samples are cut in half, dried, crushed and pulverised to 85% passing 75 microns.

This is considered to appropriately homogenise the sample. 30g fire assay with AAS finish, (Method Au - AA25) with a detection level of 0.01ppm. For Base Metals a 0.5g charge is dissolved using Aqua Regia Digestion (Method ICP41-AES) with detection levels of: Ag-0.2ppm, As-2ppm, Cu-1ppm, Fe-0.01%, Pb-2ppm, S-0.01%, Zn-2ppm. Overlimit analysis is by OG46- Aqua Regia Digestion with ICP-AES finish. Coarse gold samples greater than 0.5g/t were reassayed by screen fire assay (Method Au-SCR22) using the entire sample.

Drilling techniques

Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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).

Drilling is by diamond coring. Surface holes generally commence as PQ core until fresh rock is reached. The PQ rods are left as casing thence HQ or NQ coring is employed.

Drill sample recovery

Method of recording and assessing core and chip sample recoveries and results assessed.

Measured core recovery against intervals drilled is recorded as part of geotechnical logging. Recoveries are greater than 95% once in fresh rock.

Drill sample recovery

Measures taken to maximise sample recovery and ensure representative nature of the samples.

Triple tube drilling employed to maximise recovery.

Drill sample recovery

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.

Not Applicable since recoveries exceeds 95%.

Logging

Whether core and chip samples have been geologically and geotechnically l o g g e d to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.

Systematic geological and geotechnical logging is undertaken. Data collected includes:

 Nature and extent of lithologies.

 Relationship between lithologies.

 Amount and mode of occurrence of ore minerals.

 Location, extent and nature of structures such as bedding, cleavage, veins, faults etc.

Structural data (alpha & beta) are recorded for orientated core.

 Geotechnical data such as recovery, RQD, fracture frequency, qualitative IRS, microfractures, veinlets and number of defect sets. For some geotechnical holes the orientation, nature of defects and defect fill are recorded.

 Bulk density by Archimedes principle at regular intervals.

 Magnetic susceptibility recorded at 1m intervals for some holes as an orientation and alteration characterisation tool.

Logging

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.

Both qualitative and quantitative data is collected. All core is digitally photographed.

Logging

The total length and percentage of the relevant intersections logged.

All core is geologically and geotechnically logged.

Sub-sampling techniques and sample preparation

If core, whether cut or sawn and whether quarter, half or all core taken.

Core is sawn with half core submitted for assay. Sampling is consistently on one side of the orientation line so that the same part of the core is sent for assay. PQ core is ¼ sampled.

Sub-sampling techniques and sample preparation

If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

Not applicable as all samples are drill core

Sub-sampling techniques and sample preparation

For all sample types, the nature, quality and appropriateness of the sample preparation technique.

Samples are dried crushed and pulverised to 85% passing 75 microns. This is considered to appropriately homogenise the sample to allow subsampling for the various assay techniques.

Sub-sampling techniques and sample preparation

Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.

The use of Certified Standard Reference Materials and blanks are inserted at least every 40 samples to assess the accuracy and reproducibility. Silica flush samples are employed after each occurrence of visible gold. The results of the standards are to be within ±10% variance from known certified result. If greater than 10% variance the standard and up to 10 samples each side are reassayed. ALS conduct internal check samples every 20 samples for Au and every 20 for base metals. These are checked by YTC employees. Assay grades are compared with mineralogy

logging estimates. If differences detected a reassay can be carried out by either: ¼ core of the original sample interval, reassay using bulk reject, or the assay pulp.

Sub-sampling techniques and sample preparation

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 field duplicates are taken for core samples. Core samples are cut in ½ for down hole intervals of 1m, however, intervals can range from 0.5-1.5m. This is considered representative of the

insitu material. The sample is crushed and pulverised to 85% passing 75 microns. This is considered to appropriately homogenise the sample.

Sub-sampling techniques and sample preparation

Whether sample sizes are appropriate to the grain size of the material being sampled.

Sample sizes are considered appropriate. If visible gold is observed gold assays are undertaken by both a 30g fire assay and a screen fire assay using the entire available sample (up to several kg).

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.

Standard assay procedures performed by a reputable assay lab, (ALS Group), were undertaken. Gold assays are initially by 30g fire assay with AAS finish, (method Au-AA25). For samples with a gold value greater than 0.5ppm the entire remaining sample is screen fire assayed using wet screening to 75 microns. Ag, As, Cu, Fe, Pb, S, Zn are digested in aqua regia then analysed by ICPAES (method ME-ICP41). Comparison with 4 acid digestion indicate that the technique is considered total for Ag, As, Cu, Pb, S, Zn. Fe may not be totally digested by aqua regia but near total digestion occurs.

Quality of assay

data and laboratory tests

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.

Not applicable as all samples are assayed by independent laboratories

Quality of assay

data and laboratory tests

Nature of quality control procedures adopted (eg standards, blanks, duplicates , external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.

Certified reference material or blanks are inserted at least every 40 samples. Standards are purchased from Certified Reference Material manufacture companies: Ore Research and Exploration, Gannet Holdings Pty Ltd and Geostats Pty Ltd. Standards were purchased in foil lined packets of between 60g and 100g. Different reference materials are used to cover high grade, medium grade and low grade ranges of elements: Au, Ag, Pb, Zn Cu, Fe S and As. The standard names on the foil packages were erased before going into the pre numbered sample bag and the standards are submitted to the lab blind.

Verification of sampling and assaying

The verification of significant intersections by either independent or alternative company personnel.

The raw assay data forming significant intercepts are examined by at least two company personnel.

Verification of sampling and assaying

The use of twinned holes.

Twinned holes have not been used since this work is intended to test areas not previously explored.

Verification of sampling and assaying

Documentation of primary data, data entry procedures, data verification, data storage

(physical and electronic) protocols.

Drill Hole Data including: meta data, orientation methods, any gear left in the drill hole, lithological, mineral, structural, geotechnical, density, survey, sampling, magnetic susceptibility is collected and entered directly into an excel spread sheet using drop down codes. When

complete the spreadsheet is emailed to the geological database administrator, the data is

validated and uploaded into an SQL database.

Assay data is provided by ALS via .csv spreadsheets. The data is validated using the results received from the known certified reference material. Using an SQL based query the assay data is merged into the database. Hard copies of the assay certificates are stored with drill hole data such as drillers plods, invoices and hole planning documents.

Verification of sampling and assaying

Discuss any adjustment to assay data.

Assay data is not adjusted.

Commentary

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.

Drill hole collars are initially located using hand held GPS to ±5m. Upon completion collars are located with differential GPS to ±5cm.

Location of data points

Specification of the grid system used.

All coordinates are based on Map Grid Australia zone 55H

Location of data points

Quality and adequacy of topographic control.

Topographic control is considered adequate. There is no substantial variation in topography in the area with a maximum relief of 50m present. Local control within the Hera and Nymagee Mine areas is based on accurate mine surveys.

Data spacing and distribution

Data spacing for reporting of Exploration Results.

Drill results are exploratory in nature with piece points between 50m and 100m spacing within the mineralised structure.

Data 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.

The mineralised areas are yet to demonstrate sufficient grade continuity to support the definition of a Mineral Resource and the classifications applied under the 2012 JORC code.

Data spacing and distribution

Whether sample compositing has been applied.

Sample compositing is not 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.

Drilling is orientated to cross the interpreted, steeply dipping mineralisation trend at moderate to high angles. Holes are drilled from both the footwall and hangingwall of the mineralisation. The use of orientated core allows estimates of the true width and orientation of the mineralisation to be made.

Orientation of data in relation to 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 sample bias due to drilling orientation is known.

Sample security

The measures taken to ensure sample security.

Chain of custody is managed by YTC. Samples are placed in tied calico bags with sample numbers that provide no information on the location of the sample. Samples are delivered by YTC personnel to the assay lab or transported by courier.

Audits or reviews

The results of any audits or reviews of sampling techniques and data.

No audits or reviews have been conducted at this stage.

Exploration done by other parties

Acknowledgment and appraisal of exploration by other parties.

The area has a 50 year exploration history involving reputable companies such as Ausminda, Cyprus Mines, Grace Ore and Mining, Buka, ESSO Minerals, CRAE, Pasminco, Triako Resources and CBH Resources. Previous exploration data has been ground truthed where possible. Historic drill hole collars have been relocated and surveyed. Most of the drill core has been relocated and re- examined and resampled. This is particularly the case in older drilling where Au assays were sparse or non-existent. Some of the current staff were previously employees of Triako and CBH Resources hence retain corporate memory of activities and the quality of this work.

Drill hole

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.

Explanation

Commentary

Data aggregation methods

In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.

All reported assays have been length weighted. Grades greater than 0.1% in either Cu, Pb or Zn have been used to calculate intercepts. 5g/tAg and 0.5g/tAu are considered anomalous in the geological setting. No high cutoff has been applied. Intervals of less than 0.1% Cu, Zn and Pb are not included, except when Au>0.2g/t, Ag>5g/t

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.

Intercepts are length weighted with no cutting of grades. This may lead to elevation of intercept grades due to the presence of a narrow interval of high grade material. Such high grade zones are reported as included intercepts inside the broader intercept.

The assumptions used for any reporting of metal equivalent values should be clearly stated.

No metal equivalences quoted.

Relationship between mineralisation widths and intercept lengths

These relationships are particularly important in the reporting of Exploration Results.

Orientated drill core used to allow determination of orientation of structures and mineralisation. Orientation of the Hera and Nymagee deposits is well constrained by extensive drilling and mine exposures.

Relationship between mineralisation widths and intercept lengths

If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

See table in body of report.

Relationship between mineralisation widths and intercept lengths

If 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').

See table in body of report.

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.

See body of report.

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.

See table in body of report.

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.
