SUMMARY

The Ardlethan Tin Mine is located 3km Northwest of the town of Ardlethan in the Riverina district of NSW. Ardlethan is located 65 kilometres from Narrandera on the Newell Highway and supports a strong rural community of wheat and sheep producers. Between 1912 and 1986 The Ardlethan Tin Mine and produced over 31000 tonnes of tin, much of this between 1961 and 1986 when the mine was operated by Aberfoyle Tin NL. Overall about 10.7 million tonnes of mill tailings are stored on site as well as about 21 million tonnes of mineralised waste. The area is held under 49 mining tenements granted under the Mining Act 1906 and still current. These tenements are held under the name EOE Pty Ltd. Mill Tailings: During the main period of production from 1964 to 1986 by Aberfoyle Tin NL, automated sampling and weightometer readings were taken from the tailings stream, along with total throughput, tin production and tin recovery data. In 1978 the Main Dam was drilled by Aberfoyle to assess the size distribution and grade of the tailings material. A combination of Proline auger and reverse circulation drilling was used with samples taken at 2 metre intervals and analysed on site. The grades from this drilling compared well with the production records for the equivalent period.

Metallurgical testwork showed a recovery of 41% from a head grade of 0.172% Sn (0.182% Sn) to a 20.5% concentrate using flotation. The majority of the tin (~70%) is in the -53 um fraction.

Mineralised Waste: Waste dump volumes are established by blast hole drilling prior to firing, hauling and dumping and have not generally been systematically resampled. Fairly complete waste tonnages and grades are to be available for the period from 1964 to 1975, but only tonnages for the period from 1976 and 1985. Some estimates were calculated from adjacent periods where historical production data was missing. Aberfoyle did resample part of the White Crystal waste dump in 1983 returning grades between 0.07 % Sn and 0.40% Sn. They also trial treated some White Crystal waste through the mill in April 1983 reporting no problems with treatment but did note higher than normal lead and bismuth levels.

The resource classifications used are considered conservative, with most of the tailings and waste dump resources listed well supported by detailed production data from the operating minesite, with some estimates made for some missing data using the surrounding confirmed data. The inferred resources that are less supported are the Pre 1964 tailings and waste. These are estimated using the known tin production and back calculating the tails and waste that is likely to have been produced to achieve that production. For this reason caution is recommend when using the Pre-1964 resources in economic studies, with these resources used only with suitable disclaimers. Perhaps a range of values with the Pre 1964 numbers included and excluded would be better. It is considered sufficient or appropriate to use the remaining resources (indicated and inferred) in discounted cash flow models including valuations.

1. INTRODUCTION The Ardlethan Tin Mine is located 3km Northwest of the town of Ardlethan in the Riverina district of NSW. Ardlethan is located 65 kilometres from Narrandera on the Newell Highway and supports a strong rural community of wheat and sheep producers. Figure 1 shows the location of Ardlethan within the State. Between 1912 and 1986 The Ardlethan Tin Mine and produced over 31000 tonnes of tin, much of this between 1961 and 1986 when the mine was operated by Aberfoyle Tin NL. Overall about 10.7 million tonnes of mill tailings are stored on site as well as about 21 million tonnes of mineralised waste. This report sets out the locations, quantities and estimated tin grades of the tailings and waste dumps at Ardlethan and is prepared for Freshtel Holdings Ltd.

4. THE MILL TAILINGS - No.1 TAILINGS DAM, SPRING VALLEY TAILINGS DAM, WHITE CRYSTAL

TAILINGS DAM, HORSESHOE DAM, and SULPHIDE DAM Between 1964 and 1986 Ardlethan Tin Ltd/Aberfoyle produced some 25,000 tonnes of tin from the old Ardlethan mine, principally from the White Crystal, Ardwest and Wild Cherry pits. Prior to this various smaller operators mined the area. The tailings from the Ardlethan Tin Ltd operation are stored in a number of dams located around the old open cuts. The principal tailings dams at Ardlethan are; 1. The White Crystal Open Pit containing all mill tailings produced after September 1983. 2. The Spring Valley Tailings Dam containing mill tailings produced from mid 1977 to September 1983. 3. No.1 Tailings Dam including the Horseshoe Dam containing all mill tailings produced prior to mid 1977. 4. The small Sulphide Dam adjacent to the mill site containing residue from tin concentrate dressing to produce a

final concentrate. In August 1981 a Tailings cassiterite flotation plant was commissioned at Ardlethan. Tailings produced after that date have a portion of the free tin removed. The Main Dam, Horseshoe Tailings Dam and most of the Spring Valley Tailings Dam were deposited prior to August 1981 and have a higher free tin content. Figure 3 shows the dam locations.



Phone/Fax 0267 210 196, Mobile 0419 956 270


The Spring Valley Dam contains both older tailings produced prior to August 1981, and newer tailings produced after this date and placed on top of the older tailings. The tailings in the White Crystal pit are post August 1981 have passed through the flotation circuit.

Figure 3. Tailings Dam Locations.

5. DATA DENSITY AND DISTRIBUTION

Two sets of sampling data are available for the mill tailings, as well as a site summary;

5.1. Mill Production Data During the main period of production from 1964 to 1986 by Aberfoyle Tin NL, automated sampling and weightometer readings were taken from the tailings stream, along with total throughput, tin production and tin recovery data. In some cases the tailings tonnage and grade is given as well. Where it is not, the tailings tonnage is calculated as 99.7% of the feed tonnage, with the grade calculated from the tin recovery. The four-weekly period averages of these readings were reviewed taken from the production reports prepared by the Mine Manager and senior staff at the time. Some period reports were missing, and estimates were made by averaging the data from similar periods either side of the missing period or from other sources (e.g. Molina and Doran). This data is summarised in Appendix 3. Samples were analysed on site using a Tin Analyser (XRF) commonly used in the industry. This machine is generally accurate within a specified range provided it is calibrated correctly. As the tailings sample grades generally fall within a narrow range a high degree of accuracy is expected.

5.2. Drilling Data In 1978 the Main Dam was drilled by Aberfoyle to assess the size distribution and grade of the tailings material. A combination of Proline auger and reverse circulation drilling was used with samples taken at metre intervals and analysed on site. The grades from this drilling compared well with the production records for the equivalent period



Phone/Fax 0267 210 196, Mobile 0419 956 270


increasing confidence in the tin grades of the tailings. Appendix 4 lists the drill results. The drill samples are not used to calculate tailings tonnages and grades as it is considered that the mill production records are more accurate. The drill samples confirm the production records. The Spring Valley Dam, Horseshoe Dam, the tailings in the old White Crystal open cut and the Sulphide Dam have not been drill sampled and grades and tonnages quoted are from weightometer and automatic sampling of the mill tailings stream.

Figure 4: Tailings dam drilling by Aberfoyle in 1978.

5.3. Molina and Doran 1989. In 1989 an "Information Brochure" was produced by Aberfoyle summarising past production as well as hard rock, alluvial, tailings and some waste tonnages and grades remaining at Ardlethan. Some data from this brochure was used where no other was available. In particular, missing data for the 1976 period of production and for the Sulphide Dam were taken from this document. Production data from this report is used to estimate the Pre-1964 tailings and waste dumps. The authors were site personnel during operations.

6. METALLURGICAL TESTWORK

6.1. Aberfoyle Tin NL 1978-88 Aberfoyle Tin NL carried out a comprehensive series of metallurgical tests between 1977 and 1988 both on the older tailings in the Main Tailings Dam and on the tailings deposited in the Horseshoe, Spring Valley and White Crystal Dams. This work had the dual purposes of assisting design of the tailings flotation circuit added to their existing plant and commissioned in August 1981, and assessing the reclamation of the older tailings in the Main and others. The test work carried out has included:

· Air/Water Core drilling of the No.1 and Horseshoe tailings dams, with holes on a 50 m x 50 m grid, with samples taken each 1.5 or 3 metres and analysed by XRF for Sn. (Paterson, 1978 and Jones & Rangott,



Phone/Fax 0267 210 196, Mobile 0419 956 270


1989).

· Sizing test work of the drill samples giving a grain size distribution and distribution of the tin within each size range. The size ranges selected were set to suit the flotation tests. (Paterson 1978).

· Laboratory flotation test work considering several alternative approaches including pre-concentration, additional classification, simple sizing.

· Pilot plant scale test work.

· Metallurgical investigations associated with the operation of the tailings flotation plant in operation on the site from August 1981.

6.2. Marlborough Resources NL (Kelliher 2003) A review of the previous testwork with recommendations was carried out by Telminex/Marlborough Resources in 2003. In this review, Kelliher recommended a series of metallurgical test to develop a flow circuit to recover the tin from the tailings. These included;

· Developing a conceptual flowsheet aiming to maximise low cost gravity recovery using tin flotation as a scavenger section to produce feed for contact fuming.

· Investigating low capital/operating cost equipment including spirals and jigs.

· Testwork on drill sample composites from the whole of each of the tailings dams.

· Confirm that the flotation response of the tailings has not altered during storage.

6.3. Esker Milling and Processing Pty Ltd (Mooney 2007) Esker carried out a desktop review of the Ardlethan tailings aimed at setting the general tin recovery parameters. In this review, Esker noted that the free cassiterite at Ardlethan averages about 20µm and about 50% of the cassiterite occurs in situ as free grains in the +2µm and-53µm fractions with 7% reporting in the -3µm slimes fraction and a further 10% reports as free grains + 38µm fraction. Some 26% of the cassiterite is composite in the + 106µm fractions. They proposed the use spirals to recover the +30µm cassiterite and flotation to recover the + 3µm fractions.

Esker proposed two options to treat the Ardlethan tailings; Option 1: Gravity, Pre-concentration & Flotation (G. P. & F.)

In this circuit the + 150µm O/S is ground to less than 150µm in a ball mill, the tailings are then cycloned and the cyclone U/F is processed on a FM 1 spiral to recover any coarser cassiterite, the spiral tail is fed to a Derrick screen. Recovery is estimated between 60.7% and 67.7%. Capital costs of $16.35 million were estimated (2007).

Option 2: Gravity, Pre-concentration & Flotation (G. & F.)

In this circuit the + 150µm O/S is ground to less than 150µm in a ball mill, the tailings are then cycloned and the cyclone U/F is processed on FM 1 spiral to recover any coarser cassiterite, the spiral tail is feed to a Derrick screen this also allows for the +53µm or +75µm fractions to be discarded as all the coarser(+30mµ) tin to have been recovered. The -53µm/75µm fines are then floated to recover the finer cassiterite, in addition a proportion of the sulphides are added to the concentrate, the sulphides assist the fuming process. Recovery is estimated between 55.5% and 69.3%. Capital costs of $12.7 million were estimated (2007). The difference between cash flow at different tin prices in Year 1 for the G.& F. and the G.P.& F. is very small, but the G.&.F. is marginally higher and when capital is taken into account the margin is significant.

6.4. Sedgman 2008, 2010 The base case for the plant design was a throughput of 1.0 Mt/a of dry tailings. Two further options were also assessed, i.e. throughputs of 0.5 Mt/a and 1.5 Mt/a. Their testwork and conclusions are summarised below;

6.4.1. Samples Sedgeman arried out gravity testwork on one sample from the Main Tailings Dam and flotation testwork on two samples from the Main Tailings Dam. These were forwarded to AMDEL for metallurgical testwork. Details of these samples are given in Table 1. The results in Table 1 show that the two samples of tailings had similar tin and sulphur assays.

The results in Table 3 and Table 4 show that while there were some differences between the size by size mass

and tin distributions the overall trends were similar with the coarse material i.e. the +53 microns material

contained between 62% and 66% of the mass but only contained 30% of the tin. This was not unexpected as the

tailings were predominantly from a gravity separation plant which would have been very effective in recovering

tin down to this size range. The majority of the tin was in the finer fractions i.e. the -53 microns material

which would be more effectively recovered by tin flotation, which had been included in the original Ardlethan

processing plant for the last few years of operation.

6.4.4. Gravity Concentration

A sample of the un-sized Ardlethan tailings was subjected to gravity separation using a Falcon Separator. The sample was passed through the Falcon separator and the concentrate was collected while the Falcon tailings were re-passed through the Falcon Separator and a second concentrate was collected. The tailings were re-passed through the Falcon Separator a further three times so that a total of five concentrates were collected, filtered, dried, weighed and submitted for assay. The final Falcon Separator tailings were filtered, dried, weighed and a sub-sample was split out for size by size assay distribution.

The results of the gravity separation are given in Table 5 while the size by size assay distribution of the final Falcon Separator tailings is given in Table 6. The results in Table 5 show that the gravity separation test gave a 57% tin recovery to a concentrate that assayed 0.89% tin.

6.4.5. Flotation Testwork

A series of flotation tests were carried out with various numbers of flotation stages, flotation residence times

and pulp densities. The results of the flotation tests are summarised in Table 7.

The results in Table 7 and show that Test 3 gave the best grade recovery response with a rougher concentrate grade of 2.0% tin at an overall tin recovery of 70.7%. This test which had been conducted at a pulp density of 15% solids, with a sulphide pre-flotation stage plus high initial collector addition dosage, was used as the basis for the subsequent cleaner tests. Unfortunately, while test 7 had been planned to be conducted at 15% solids it was later discovered that it had actually been conduct at 30% solids.

The results of the locked cycle test were used as the basis for the initial processing plant design. The locked

cycle test was to be conducted at 15% solids, however it was later found to have been conducted at 30%

solids.

A further series of tests were undertaken to determine the effects of pulp density on tin flotation

performance, the results of which are summarised in Table 9. The results show that the flotation

performances were similar for the tests with pulp densities between 15% and 25% solids. The tests at 30%

and 35% solids gave much higher final concentrate grades at similar recoveries. The reason for the

improvement in flotation performance may have been due to the effects of amount of acid added to

maintain the optimum pH for flotation. As the pulp density decreased the acid addition had to be

increased to maintain the pH at approximately 4.5.

On the basis of these results the preliminary plant design included operating the flotation circuit at 30% solids.

A series of tests aimed at determining the effects of acid addition and site water were conducted by AMDEL.

The results showed very little differences between the tin flotation tests conducted using Perth tapwater, with

and without acid addition, and site water. The use of acid with Perth tapwater and/or site water appears to have

been beneficial with regard to the final concentrate grade, however this may have been due to operator technique

and would require further testwork to confirm whether or not this was a real effect. Nevertheless the rougher

flotation results were all very similar irrespective of the water used for flotation.

On the basis of these results it can be concluded that the existing site water could be successfully used for

the flotation in the proposed tin tailings retreatment plant.

6.4.6. Process Plant Description

The base case for the plant design is a throughput of 1.0 Mt/a of dry tailings. Two further options were also

assessed, i.e. throughputs of 0.5 Mt/a and 1.5 Mt/a.

· Testwork showed a recovery of 41% from a head grade of 0.172% Sn (0.182% Sn) to a 20.5% concentrate using flotation. This would result in a tin production to tin flotation concentrate of 705 t/a for the 1.0 Mt/a throughput option. A summary of the major design criteria is shown in Table 10.

· The majority of the tin (~70%) is in the -53 um fraction.

· Concentrate thickening and handling; and



Phone/Fax 0267 210 196, Mobile 0419 956 270


· Tails t hickening.

Final tin concentrate product will be packaged into 1 tonne capacity bags and loaded on pallets for transport.

Screening and de-sliming

The screening and de-sliming area will be used to remove the +100 µm and -2 µm fractions of the reclaimed tailings. A trommel screen will remove the +2 mm material which will be sent to final tails. A stacked Derrick screen will treat the underflow from the trommel screen to give a nominal product size of -100 µm.

A two or three stage cyclone bank will be used to remove the slimes (-2 µm fraction) from the Derrick screen underflow. The -100 µm +2 µm fraction will be held in a surge tank to feed the flotation circuit.

Flotation

The flotation circuit will consist of sulphide flotation circuit, 2 stage rougher flotation and a 3 stage cleaner flotation circuit. The flotation circuit will operate at approximately 30% solids.

7. RESOURCE CATEGORIES - TAILINGS DAMS

Main Dam and Horseshoe Dam: As the grade and tonnage of the 1964-1985 tailings in the Main Tailings Dam has been reasonably confirmed by both continuous weightometer/automatic sampling of the tailings stream during milling, and by drilling of the dam by Aberfoyle in 1978 confidence in this resource is sufficient for it to be classified as Indicated Resources under the JORC Code. Also assumed to be within the Main Dam will be an estimated 1.9 million tonnes of pre 1964 tailings produced by various operators. The quantity, grade of this material is estimated by back calculation from the known quantity of tin produced. A conservative estimate of the original head grade and tin recovery to a saleable product is used in these calculations. Spring Valley Dam: The Spring Valley Dam contains tailings produced both before and after introduction of the flotation circuit in August 1981. Grades and tonnages of both pre and post August 1981 tailings are calculated from mine records detailing continuous weightometer/automatic sampling of the tailings stream during milling. These resources are classified as Inferred under the JORC Code. White Crystal Pit: Tailings disposal into the White Crystal Pit commenced in September 1983 and continued until closure of the mine in early 1986. Grades and tonnages of tailings are calculated from mine records detailing continuous weightometer/automatic sampling of the tailings stream during milling. These resources are classified as Inferred under the JORC Code. Sulphide Dam: Incomplete records are available of the grades and tonnages in the Sulphide Dam and the figures assumed in Table 1 come from estimates by Molina an Doran in 1989. These are partly confirmed by mine records and Paterson's 1978 drill sampling. These resources are classified as Inferred under the JORC Code.

8. RESOURCE CATEGORIES - WASTE DUMPS

Waste dump volumes are established by blast hole drilling prior to firing, hauling and dumping and have not generally been systematically resampled. Fairly complete waste tonnages and grades are to be available for the period from 1964 to 1975, but only tonnages for the period from 1976 and 1985. Some estimates were calculated from adjacent periods where historical production data was missing. Table 12 shows the tonnages and grades and Figure 4 shows the dump locations. Aberfoyle did resample part of the White Crystal waste dump in 1983 returning grades between 0.07 % Sn and 0.40% Sn. They also trial treated some White Crystal waste through the mill in April 1983 reporting no problems with treatment but did note higher than normal lead and bismuth levels. All of the mineralised waste dump resources are classified as Inferred Resources under the JORC Code. While the tonnages and grades are generally well established from the production records, the exact location of individual periods of production within the dumps is not known, except for the White Crystal Waste Dump. In addition, the Pre-1964 waste is inferred from the known tin production and could differ substantially in grade and tonnage from the figures presented in Table 12, although probably to a lesser extent in terms of contained tin. To raise these Inferred Resources to Indicated Resource or higher category, systematic sampling of the dumps will be required, both on the dump flanks and internally through drilling. This is likely to identify higher and lower grade sections of the dumps for selective reclamation if desired.

9. USE OF RESOURCES IN ECONOMIC CALCULATIONS AND VALUATIONS. Section 20 of the JORC Code states: "Caution should be exercised if this category is considered in technical and economic studies" The resource classifications used are considered conservative, with most of the tailings and waste dump resources listed well supported by detailed production data from the operating minesite, with some estimates made for some missing data using the surrounding confirmed data. The inferred resources that are less supported are the Pre 1964 tailings and waste (see Tables 11 and 12). These are estimated using the known tin production and back calculating the tails and waste that is likely to have been produced to achieve that production. For this reason caution is recommend when using the Pre-1964 resources in economic studies, with these resources used only with suitable disclaimers. Perhaps a range of values with the Pre 1964 numbers included and excluded would be better. It is considered sufficient or appropriate to use the remaining resources (indicated and inferred) in discounted cash flow models including valuations.

10. DEFINITIONS

A ‘Mineral Resource’ is a concentration or occurrence of material of intrinsic economic interest in or on the Earth’s crust in such form, quality and quantity that there are reasonable prospects for eventual economic

extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories. An ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability. An ‘Indicated Mineral Resource’ is that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.

ARDLETHAN OLD TAILINGS DAM - TEST DRILLING RESULTS (By Paterson 1978)

(Source: Report by RG Paterson June 1978 "ARDLETHAN TAILINGS : TONNAGE AND GRADE ASSESSMENT" )

Aim of drilling was to ascertain proportion of material in floatable size range -106 to +5 microns and the tin assay of this size range.

Dams drilled on 50m square grid pattern

Samples taken at 3.0m intervals

1200m of drilling completed for 411 samples which were then dried, sized and assayed

Cross sections of drill holes drawn across the dams and the volume of tailings determined from these sections

The full tailings assay, the fraction of material in floatable material and the product of the latter two (or overall recoverable grade)down the holes.

plotted against each 3 metre section

Total tonnage determined using an S.G. of 1.59

Grade determined by taking the arithmetic mean of all full 3 metre samples

Part samples at the bottom of the dam were rejected as being unreliable

A total 335 samples were meaned to produce the average grade of 0.197% Sn. This exactly the same as mill assay records.

The mean feed float fraction was meaned from the 335 samples as 0.342 (or 34.2%)

Float feed assay meaned at 0.318% Sn

Bench plans at 6.0m intervals across the dam were constructed for Float Feed Fraction, Float Feed Assay and Float Feed Fraction x Float Feed Assay

Apparent from these plans there are less favourable units for the float plant near the old cyclone walls and original tailings outlet position, i.e. the northern section of the dam above the tailings wall.

Total tonnage across the Old Dams (except sulphide Dam which had an estimated 15,000t at 2.00% in 1978 and Horseshoe Dam which was too wet to measure was:

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.

* Whether sample sizes are appropriate to the

grainsize of the material being sampled.

* Section 5



Phone/Fax 0267 210 196, Mobile 0419 956 270



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.

* 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.

* Section 5.1, Section 8

Verification of

sampling and assaying.

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

* The use of twinned holes.

* Sections 5.1 and 5.2, Section 8

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.

* Quality and adequacy of topographic control.


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.


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.


Audits or

reviews.

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


Estimation and reporting of Mineral

Resources

(criteria listed in the first group, and where

relevant in the second group, apply also to this

group)

Database

integrity.

§ Measures taken to ensure that data has not

been corrupted by, for example, transcription

or keying errors, between its initial collection

and its use for Mineral Resource estimation purposes.

§ Data validation procedures used.

§ Sections 7 and 8

Geological interpretation.

§ Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral

deposit.

§ Nature of the data used and of any

assumptions made. § The effect, if any, of alternative

interpretations on Mineral Resource

estimation.

§ The use of geology in guiding and controlling Mineral Resource estimation.

§ The factors affecting continuity both of grade

and geology.

§ Sections 7, 8 and 9



Phone/Fax 0267 210 196, Mobile 0419 956 270



Dimensions.

§ The extent and variability of the Mineral

Resource expressed as length (along strike or

otherwise), plan width, and depth below

surface to the upper and lower limits of the Mineral Resource.


Estimation

and modeling techniques.

§ The nature and appropriateness of the

estimation technique(s) applied and key assumptions, including treatment of extreme

grade values, domaining, interpolation

parameters, maximum distance of

extrapolation from data points. § The availability of check estimates, previous

estimates and/or mine production records

and whether the Mineral Resource estimate

takes appropriate account of such data. § The assumptions made regarding recovery of

by-products.

§ Estimation of deleterious elements or other

non-grade variables of economic significance (e.g. sulphur for acid mine drainage

characterisation).

§ In the case of block model interpolation, the

block size in relation to the average sample spacing and the search employed.

§ Any assumptions behind modeling of

selective mining units.

§ Any assumptions about correlation between variables.

§ The process of validation, the checking

process used, the comparison of model data

to drill hole data, and use of reconciliation data if available.


Moisture. § Whether the tonnages are estimated on a dry

basis or with natural moisture, and the method of determination of the moisture

content.

§ Tables 11 and 12

Cut-off parameters.

§ The basis of the adopted cut-off grade(s) or quality parameters applied.

§ No cut off applied

Mining

factors or assumptions.

§ Assumptions made regarding possible

mining methods, minimum mining dimensions and internal (or, if applicable, external)

mining dilution. It may not always be possible

to make assumptions regarding mining

methods and parameters when estimating Mineral Resources. Where no assumptions

have been made, this should be reported.

§ No assumptions made

Metallurgical factors or

assumptions.

§ The basis for assumptions or predictions regarding metallurgical amenability. It may

not always be possible to make assumptions

regarding metallurgical treatment processes

and parameters when reporting Mineral Resources. Where no assumptions have been

made, this should be reported.

§ Section 6

Bulk density. § Whether assumed or determined. If assumed, the basis for the assumptions. If determined,

the method used, whether wet or dry, the

frequency of the measurements, the nature, size and representativeness of the samples.

§ Section 6



Phone/Fax 0267 210 196, Mobile 0419 956 270



Classification. § The basis for the classification of the

Mineral Resources into varying confidence

categories.

§ Whether appropriate account has been taken of all relevant factors. i.e. relative confidence

in tonnage/grade computations, confidence in

continuity of geology and metal values,

quality, quantity and distribution of the data. § Whether the result appropriately reflects the

Competent Person(s)’ view of the deposit.


Audits or reviews.

§ The results of any audits or reviews of Mineral Resource estimates.

§ No audits

Discussion of

relative

accuracy/

confidence.

§ Where appropriate a statement of the

relative accuracy and/or confidence in the Mineral Resource estimate using an

approach or procedure deemed appropriate

by the Competent Person. For example, the

application of statistical or geostatistical procedures to quantify the relative accuracy

of the resource within stated confidence

limits, or, if such an approach is not deemed

appropriate, a qualitative discussion of the factors which could affect the relative

accuracy and confidence of the estimate.

§ The statement should specify whether it

relates to global or local estimates, and, if local, state the relevant tonnages or volumes,

which should be relevant to technical and

economic evaluation. Documentation should

include assumptions made and the procedures used.

§ These statements of relative accuracy and

confidence of the estimate should be

compared with production data, where available.

§ Sections 5 to 8. Accuracy based on

production data and drilling data
