INTERTEK INDONESIA: Intertek, represented by PT Intertek Utama Services, has been providing analytical services inIndonesia since 1993.

In addition to operating one of South East Asia’s largest commercial analytical laboratories in Jakarta, encompassing minerals,environmental, petroleum geochemistry and palm oil testing, Intertek operates sample preparation facilities throughout theregion.

Currently, the Company has sample preparation facilities in Medan, Padang, Manado and Sumbawa Besar in Indonesia, Manilaand Surigao in the Philippines and Lae, Papua New Guinea. Whilst these facilities offer services to all clients, Intertek alsooperates dedicated sample preparation sites for specific clients in both Indonesia and PNG. Fire Assay Gold is also available inLae, PNG.

Utilising its depth of expatriate and national staff, Intertek also provides 24 /7 mine site laboratory operations for the NewcrestGosowong gold mine and Newmont Batu Hijau copper/gold mine.

Analytical services are offered to clients from Saudi Arabia and the Middle East to Thailand, Laos, China, Vietnam, Philippines,Malaysia, Indonesia, Papua New Guinea and Australia.

QUALITY ASSURANCE AND SAMPLE TRACKING: Our Jakarta laboratories hold ISO 17025 accreditation for their minerals,environmental and petroleum analyses whilst the Company is accredited by FOSFA for palm oil testing.

The ISO 17025 accreditation ensures international standards are maintained in the laboratories’ procedures, methodology,validation, QA/QC, reporting and record keeping. A sophisticated Laboratory Information Management System (LIMS) isin place for sample tracking, scheduling, quality control and electronic reporting. This is complemented by bar coding ofsamples in the Jakarta laboratories.

Certified Reference Materials, blanks, splits and replicates are analysed with each batch of samples. Selected samples are alsore-analysed to confirm anomalous results. These quality control results are reported along with the sample values in the finalreports. Intertek also participates in a number of regular international proficiency round robins and client specific proficiencyprograms.

REFINERY REPRESENTATION: Intertek offers a team of trained superintendents to minimize client risk by the supervisionof precious metal refinery evaluation smelts and export shipments. Our staff will reduce the risk of melt losses and sampling biasby strictly monitoring the smelting process. This includes receipt of material, equipment use, clean up and product handover.

ENVIRONMENTAL SERVICES DIVISION: Intertek’s environmental division provides laboratory testing services as well asenvironmental consulting services to numerous industries in Indonesia (mining, oil & gas, manufacturing and utilities).

These services include trace level testing of water, soil, sediment, air and biological tissue in addition to testing more complexsamples such as wastewater and solid waste. Our consulting services support environmental studies which must be conductedby our clients (e.g. AMDAL, RKL/RPL, EBS, for their development plans).

Additional services include the provision of technicians for collection of samples in the field. Sample collection containers,preservatives and coolers are shipped to most locations throughout Indonesia.

PETROLEUM SERVICES DIVISION: Based in Jakarta and also using the extensive capabilities of its Singapore and Malaysianlaboratories, Intertek offers a range of sampling, onsite and laboratory analyses for Oil and Gas clients.

These services include; gas composition analyses, source rock screening, bitumen and oil composition analyses, trace ele-ments, machinery lubrication analysis and interpretation, on-site mercury analyses and gas cylinder rental.

Intertek technicians conduct onshore and offshore sampling, conducting analyses at site or returning to the Jakarta laboratorywith samples for analysis.

COAL SERVICES DIVISION: Intertek has two coal laboratories in Samarinda and Banjarbaru, offering inspection and testingservices such as proximate and ultimate analysis.

Sample PreparationCorrect sample preparation procedures are best selected through consultation with laboratory management prior to samplesubmission.

The schemes listed below are a guide only as the choice of procedure will depend on the sample mineralogy, equipment utilized,time constraints and client budget.

In general, two schemes are offered, Total Preparation and Partial Preparation.

Total Preparation

The entire sample is dried, crushed and fine pulverized. Large samples will require multi-bowl pulverizing, after which the sampleis recombined before the assay pulp is taken.

Partial Preparation

The sample is dried and crushed before a split is taken for fine pulverizing. The size of the split and whether it is taken manually(Riffle) or mechanically (Rotary Sample Divider) will depend on the client’s requirements and equipment in use.

General Information

Standard drying temperature is set at 105oC but samples may be dried at 60oC if mercury is to be analysed.

Samples may also be roasted to remove sulphides and other interferents before fire assay.

Intertek nominates 95% passing specific sieve sizes for crushing and pulverizing, however, the ability to achieve these percent-ages will depend on the sample size and mineralogy and the equipment in use at a particular Intertek facility.

Quality control procedures include a 1 in 15 resplit after crushing or pulverising for partial preparation and after pulverizing fortotal preparation. These samples are analysed and reported to the client. Also sizing tests are carried out on 1 in 20 assay pulpsat 75um (200#) to monitor the pulverising stage. These values are available to be reported, on request.

It is standard Intertek practice that all crushers and pulverisers are cleaned with barren material and/or bowl washing betweeneach sample to minimize carry-over contamination.

Sample Storage

Sample residues and pulps will be stored without charge for three months, after which the client will be contacted with the choiceof samples being returned, discarded or stored for a fee.

Sample Waste DisposalIntertek disposes of its chemical and hazardous wastes ethically and using qualified disposal contractors. A sample disposalcharge of US$0.20 is applied to all samples submitted. This charge is not subject to discount.

Intertek offers a range of analyses for precious metals; gold, platinum and palladium.

Fire Assay schemes involve fusing the sample with a litharge based flux and collecting the precious metals in a lead button. Aftercupellation the resulting prill is dissolved in aqua regia and the gold is determined by AAS for routine samples. Samplesexceeding the upper limits of the method are automatically re-assayed utilising a high grade gravimetric method.

Alternatively, for low level samples, graphite tube atomization via AAS may be used for gold, platinum and palladiumdeterminations.

Samples with sulphide or base metal matrices may be roasted or have the flux mixture changed to accommodate the matrix.

FA30

30g of sample is analysed. This scheme is suitable for higher concentration samples, those generated in ore body definitiondrilling and samples with a sulphide and/or copper matrix. Detection Limit (DL) 0.01ppm, Upper Limit (UL) 30ppm.

FA50

50g of sample is analysed. This scheme is suitable for exploration samples when the identification of anomalous samples isimportant. DL 0.005ppm, UL 50ppm. A recommended option for grassroots exploration is the use of a new fire assay pot for eachsample.

FA51

50g of sample is analysed. This scheme is recommended for routine samples that are not subject to any matrix issues norparticularly low or high concentrations. DL 0.01ppm, UL 50ppm.

FA10 and FA12

A gravimetric finish is used for samples exceeding the upper limits of the routine methods or for known high concentrationsamples.

FA55

For low level exploration samples where 50g is analysed and a graphite tube atomisation finish is employed to give lowdetection limits. Platinum and palladium can also be determined as additional elements. D.L Au (1ppb), Pt (5ppb), Pd (1ppb).

FA20

Screen fire assay is used to identify coarse gold and typically involves sieving 1 kilogram of sample at 75um (200#). The entireoversize and duplicate undersize samples are fired and the weighted average is calculated and reported.

Cyanide Leachable Gold

Cyanide soluble gold is determined by leaching the sample in a dilute cyanide solution.

High Grade Bottle Roll methods are used for ore grade samples and leach conditions can be customised to client requirements.

Additional optional information includes stages pH and cyanide levels, total cyanide consumption along with tail recovery andanalysis. Accelerated leaching using Leachwell is also available.

BLEGS are a low level exploration method commonly used for stream sediment samples to identify low value anomolies.Two techniques are offered, standard leach and GTA finish or a zinc collection method (based on the Merril Crowe technique)Copper and silver may be determined as additional elements..

Fusion Analysis by XRFX-ray fluorescence (XRF) is an instrumental method of analysis in which a sample, pressed into a pellet or fused into a disc, isintroduced into an X-ray beam. The sample is fused with a borate flux, the fusion process breaks down the sample matrixcompletely thus the results obtained are “total”.
