In the periods 1845 to 1877 and 1971 to 1981 the Monster Mine at Burra produced a total of 2.7Mt @ 3% Cu, and was at one time the largest mine in Australia and the second largest Copper mine in the world.

Phoenix is exploring for:-

Non Sulphide Copper mineralisation in the near surface along strike and in similar hosts to the Monster Mine.

Sulphide and Non Sulphide Copper Ore at depth beneath previously worked oxide or carbonate copper mineralisation.

Phoenix is working to establish a robust genetic model for copper mineralisation throughout the Adelaide Geosyncline.

Phoenix Copper utilise field portable X-Ray Fluorescence analysers to collect geochemical data over all of our project areas. The bulk of the Burra tenement package is perfect for soil sampling.

Phoenix  Copper  Ltd  has  become  the  first company in the world to use the innovative data  assimilation  combination  in  the  form of the Innov‐X Omega Explore Package.

The Omega 6000 and Niton XL3T have given repeatable results in most conditionsThe Trimble Nomad running MapInfo Discover Mobile has the ability to show MapInfo TAB files and position the user in relation to tenements, topography, previous sampling, or other informationIt is a powerful tool for mapping and sampling

Prior to utilising the XRF handheld Analyser Phoenix Copper Geologists and Field Technicians would have to:-Carry a shovel, sieve and bag

of samples into the field.Dig the surface off the area

to be sampled.Sieve out the coarse material.Pack and carry the samples

back to the vehicle

Now they:-Scuff the ground with their

boots - taking a few centimetres off the surface, Place the analyser down

carefully Press the triggerTake the readingAccept GPS positionAdd commentObserve the data

Prior to using the XRF handheld Analyser.

Staff would dispatch the samples to a laboratory for assay.

Wait weeks for results to Wait weeks for results to returnreturn..

Then instigate an infill program over the most anomalous areas and go through the whole cycle again.

Two months later a decision could be made on the geochemical prospectivity of the ground.

ZZZZZZZZZZ

Now the assays are available on screen as soon as you press the trigger. You can react to the information immediately and adjust your

sampling program to suit.

Or call up the drill rig as soon as you want.

The FPXRFs have proven remarkably accurate against laboratory assaying on 120 and 60 second readings.(The Lab assays were taken on 10g of sieved soil samples pulverised mixed and digested using a mixture of nitric and hydrochloric acid. The resultant solution was bulked to volume with water and quantified using ICPMS with a 2ppm Cu low level of detection).

The Assays when contoured generally produced the same broad shape, and at least highlighted the same peak of the anomaly.

One month of soil sampling data

A month of conventional soil analyses

An experiment was undertaken to determine if accurate XRF analysis can be obtained in 30 seconds.

•The accuracy of XRF analysis taken in 30 seconds versus 60 seconds measured against Laboratory analysis, was undertaken on a line of samples in the Spalding area. The soils are thin layers of calcareous silty clays overlying and surrounding subcropping Neoproterozoic siltstones, shales and dolomites.

•Five analyses were taken on the same ground at about the same point:•Sieved dry soil sample analysed in a laboratory via Aqua Regia with mass or optical spectrometer finish. •Niton XL3T XRF analysis 30 second reading and Niton XL3T analysis 60 second reading•Omega 6000 XRF analysis 30 second reading and Omega 6000 XRF analysis 60 second reading

An experiment was undertaken to determine if FPXRF Analysers provide Accurate Results in Damp Soil

The experiment was undertaken on the 6,288,000N (AGD94) line of samples in the Spalding area. The soils are thin layers of calcareous silty clays overlying and surrounding subcropping Neoproterozoic siltstones, shales and dolomites.

Five analyses were taken on the same ground at about the same point:Sieved dry soil sample analysed in a laboratory via Aqua Regia with mass or optical spectrometer finish. Niton XL3T XRF analysis 60 second reading in damp soil after a rainfall and 60 second reading dry soil.Omega 6000 XRF analysis 60 second reading damp soil after a rainfall and 60 second reading dry soil.

Myth Busters60 sec readings have proven only slightly better than 30sec readings on data from the orientation line at Spalding.Readings taken in damp conditions were only marginally less accurate than those taken on dry soils.

SafetyDifferent units emit different radiation levels and training required to use safely

Punctured Window

Manual handlingWeight Ease to carryNumber of components to take into field (some have short battery life and require all the charging equipment nearby)Fragility almost all the analysers are very fragile and extreme care must be taken to protect them from knocks and bumps.Detector window penetration by stones, sticks or stubble - repair cost up to $6K

Thermo Scientific is introducing the new Niton XL3t XRF Analyzer with GOLDDTechnology a new type of Silicon Drift Detector

This new analyser deliversLight element detection (Mg, Al, Si, P, S) without helium or vacuum purging The lowest limits of detection and the fastest analysis availableTrue lab-quality performance in a handheld instrument

This all adds up to the GOLDD advantage10 x better than conventional Si PIN detectors3 x better than analyzers with off-the-shelf SDD detectors

Optimized, higher voltage

X-Ray Tube means greater excitation

Larger drift detector & optimized geometry mean more x-ray counts for faster/more precise readings

• Best ResolutionThe X-Press SDD is designed to operate at 150eV resolution compared to a traditional SiPiN’s 175eV re – the best choice for resolving difficult elements/peaks.

• Highest Count RatesThe X-Press SDD can sustain up to 100kcps without loss of resolution compared to

10-15kcps for PiN’s – the best choice for improving LOD’s and analyzing Light Elements (lower atomic # elements - LZEs) such as Mg, Al, & Si;

• Best Peak-to-Background The X-Press doesn’t have noisy backgrounds to mask elements/peaks of interest like SiPiN’s can have – the best choice for complex matrices and for applications requiring the highest levels of precision and analytical confidence.

PNX decided to use the XRF on 60sec readings for first pass and 30sec readings for infill analysis on Cu projects.Therefore depending upon line spacing and topography about 240 analyses can be taken in an average 8 hour day.Phoenix has collected over 25,000 analyses in the past 12 months Laboratory assays with a similar but less extensive suite of elements cost PNX ~$37.50 each and we have taken 2000 of those as check and follow up assays.Had the XRF sampling been done conventionally it would have taken an extra year or two and cost an extra $937,500 The ~$75,000 investment was well worth while.

Using Field Portable X-Ray Fluorescence analysers, with integrated GPS has been:

Cost effective Cost effective saving almost $1million in assay cost in 12 months.

AccurateAccurate having been tested against laboratory assays for copper.

FastFast allowing quick identification of anomalous areas and or increased density of geochemical coverage those zones of interest.

It provides an excellent way to explore an excellent way to explore for minerals.
