Summary
Microdiamond Extraction, Selection and Description
Microdiamond extraction, selection and description was performed on a single sample (VL-04-
01). The caustic dissolution residue was collected on a 150 mesh (100 |j.m) screen, and then
submitted for Frantz magnetic separation to concentrate the microdiamonds into the non-
paramagnetic fraction. The results of the diamond selection process are reported as a
Certificate of Analysis in Appendix A.
As part of our on-going commitment to providing a high quality service and to monitor the
recovery efficiency of sample material in each kiln pot, we put spikes in each sample and
recovered these spikes at the end of the process during microdiamond selection. The recovery
of relatively coarse, 35 mesh spikes was 10007o whereas the recovery of relatively fine, 80 mesh
spikes was 8007o.
A detailed description of the microdiamond extraction process, as well as a generalized
processing flow sheet, may be found in Appendix B.

EXPLANATION OF MICRODIAMOND EXTRACTION AND SELECTION PROCEDURE AND FLOWSHEET
Microdiamond Extraction, Selection and Description Mineralogical Services Rainer Skeries SGS Lakefield Research Ltd. Lr2401345MI0008-MA Y04
DIAMOND EXTRACTION BY CAUSTIC DISSOLUTION
Introduction
Caustic dissolution of exploration samples efficiently produces a concentrate from which diamonds can readily be extracted during microscopic examination. The process takes advantage of diamond's property of high resistance to caustic soda (NaOH), eliminating diamond size reduction and loss that often occurs during extraction procedures that rely on crushing and attrition milling.
Procedure
The samples are processed according to the attached flowsheet. Very few minerals survive the harsh chemical attack, therefore weight reductions commonly exceed 9907o of the initial sample weight.
As-received samples are divided into equally sized charges of less than 8 kg. Smaller charge sizes are necessary if the sample contains a high proportion of carbonate minerals, which are vigorously reactive with NaOH (the carbonate content is evaluated by an acid test prior to charge preparation). If a high proportion of the sample is composed of fragments larger than 8 cm, simple breakage, crushing or attrition milling may be required for an effective dissolution, or the length of the dissolution process may be increased. Client consultation and approval is necessary before any size reduction of the sample is initiated.
After digestion in molten caustic soda, the sample is poured onto a large-diameter 200 mesh (74 jim) screen. The + 200 mesh residue is liberated from the NaOH by washing the sample in a series of water and acid leach (HCI) baths. Once all of the NaOH is dissolved and removed, the concentrate is dried and screened on a 6 mesh screen to remove undigested material. The undigested material is examined microscopically by a mineralogist. If a significant amount of +G mesh remains, or if the material consists of possible diamondiferous rock fragments, further digestion may be required. If the undigested material is of insignificant size or not considered as a possible source of diamonds, the -6 mesh residue is further processed by a two (possibly three if the residue is large) stage magnetic separation procedure utilising a permanent magnet and a Frantz Barrier Magnetic Separator.
The magnetically characterised residue is then submitted for microscopic examination and diamond selection. In addition to diamonds, the residue may contain partially undigested indicator minerals, colourless to opaque spinel, garnet, ilmenite, graphite, moissanite, zircon and kyanite. Each of the magnetic fractions is examined at a magnification of 40x using a binocular microscope. Grains of questionable mineralogy are examined using a scanning electron microscope equipped with an energy dispersive spectral (SEM-EDS) analyser. Although each magnetically characterised fraction is examined, particular emphasis is given to the diamagnetic portion.
The X, Y and Z dimensions of selected microdiamonds are measured in millimetres. Macrodiamonds are weighed individually while microdiamonds are weighed in groups of 20 or 30, with the milligram weight, in each case, converted to carats. The colour, clarity and morphology of each diamond are determined and all observations reported in a Certificate of Analysis. Synthetic diamonds released into a sample by diamond drill bits are selected and reported as "syndites" on the diamond description sheet.

Quality Control
Routine quality control tests are utilised to evaluate the efficiency of the caustic dissolution processing technique. Since the beginning of 2004, we have started reporting SGS-LR spike recoveries together with diamond results. During 2003, we experimented with the addition of two sizes (80 and 35 mesh) of synthetic diamond spikes with great success including one project, which ran for approximately six months, in which one of our clients used "Congo Rounds" as natural diamond spikes. Diamond spikes recoveries for our client's spikes ran at 9507o whereas recoveries for our 35 and 80 mesh synthetic diamond spikes were 96 07o and 9307o, respectively.
In addition to the above aspect of Quality control, each caustic dissolution residue is picked twice by separate diamond pickers. Questionable grains are examined by SEM-EDS for verification.
Every effort is made at each stage of sample handling during caustic dissolution, residue preparation and diamond picking to eliminate the possibility of contamination. These steps include:
* A rigorous sample tracking procedure.* Dedicated screens and equipment for each sample during sample processing.* Replacement of screens between each sample after pouring caustic soda.* Thorough washing and scrubbing of all sample containers.* Thorough cleaning of equipment used to prepare caustic residues between each
processed sample.* Sandblasting of each kiln pot between clients projects to ensure the removal of any
microdiamonds or indicator minerals.
Customized flowsheets for sample processing utilising caustic dissolution and other sample preparation techniques (magnetic, gravity, flotation, acid leaching, etc.) can be developed, in consultation with the client, to meet specialised requirements.
SGS Lakefield Research Limited is not responsible for the determination of the origin, quality or valuation of any diamonds recovered unless otherwise instructed by the client.
