    FOUR HUNDRED AND SEVEN MACRO AND MICRO DIAMONDS RECOVERED FROM 258 KG
    OF SAMPLES COLLECTED FROM BEHRADIH KIMBERLITE, THE VAST MAJORITY OF
    WHICH ARE CLEAR, COLOURLESS STONES.
    The Chhattisgarh joint venture partners ("Oropa Limited and
    B.Vijaykumar Technical Services Pvt Ltd") recently completed a fine
    diamond and mineralogical sampling programme comprising the
    collection and analysis of eight weathered surface samples with a
    combined weight of 258 kg from various points located within the
    Behradih kimberlite as illustrated on Figure 1 in the attached
    Appendix "A". The samples, (BSS#01-08) were airfreighted to Perth in
    August for screening and detailed analyses. Detailed individual
    sample results from these eight samples are tabulated in Table 1 in
    Appendix "A". It should be noted that all eight samples contained
    diamonds and abundant indicator minerals. Detailed petrographic
    analysis of fresher kimberlite obtained from sub-surface sampling
    will be necessary to more precisely evaluate the nature and
    variability of the kimberlite diatreme.
    A total of 497 micro and macro (-0.4mm) diamonds have now been
    recovered from the nine weathered Behradih kimberlite samples,
    including the original sample collected in July. Results of screening
    analysis through square mesh screens are tabulated below;
    BEHRADIH SURFACE KIMBERLITE SAMPLE DIAMOND SIZE DISTRIBUTION
    MESH SIZE 0.1 0.15 0.21 0.30 0.43 0.60 0.85 1.18
    mm mm mm mm mm mm mm mm
    Diamonds 262 141 55 28 5 3 2 1
    Recovered
    The recovered diamonds have been subjected to size distribution
    analysis using Rombouts sampling and statistical evaluation of
    diamond deposits methods (L. Rombouts, Journal of Geochemical
    Exploration 53-1995). Figure 1 in Appendix "A" extrapolates the
    plotted diamonds' as Cumulative Carats per hundred tonnes versus Size
    and indicates that grade and size may be significant. Statistical
    analysis of the size distribution also suggests that diamonds
    exceeding 1 carat in size are probable in this kimberlite.
    Analysis of the diamond populations observed within the fine diamonds
    is also encouraging. The data suggests a large proportion of good
    shapes and clear, white stones. As per the majority of kimberlite
    diamond populations, resorption features are apparent, although the
    overall degree of resorption does not appear to be dominant as is
    the case with kimberlites containing a high proportion of low value
    diamonds. Further evaluation of the stone characteristics is
    currently in progress.
    Although it is not possible to make precise deductions regarding
    grade and size distribution from the 318 kg of surface kimberlite
    material collected to date, it is clear that the Behradih pipe has
    fine diamond counts and, most significantly, yields macro-diamonds
    from very small sample sizes. Analysis of the pyrope garnets and
    chrome spinels recovered from the Behradih samples as produced in the
    accompanying Figures 3, 4 and 5 also provide supporting evidence that
    the Behradih kimberlite sampled source material within the diamond
    stability field and is diamond bearing. Available micro-diamond andmineralogic
    al data points to the presence of measurable grade.
    The Behradih kimberlite is located on the western side of the Raipur
    kimberlite pipe cluster and it is accessed from the main interstate
    highway passing through the block. In the mid-1990's the Directorate
    of Geology and Mines ("DGM") completed a diamond coring programme
    comprising five holes for a total of 708 metres (one vertical hole
    and four angled holes), which indicated that the Behradih kimberlite
    persists to a minimum of 180 metres. This drill pad is located in the
    central portion of the kimberlite and is marked on the accompanying
    map. However, the coring programme did not establish whether the pipe
    was single or multi phased (more than one kimberlite body contained
    within the one diatreme). The Behradih kimberlite has a surface area
    of approximately 3.2 ha, as determined by the DGM. The joint venture
    partners are nearing agreement with their negotiations with the DGM
    to purchase these five cores for preliminary studies. If successful,
    the cores will be airfreighted to Australia and Republic of South
    Africa ("RSA") for detailed mineralogy evaluation.
    The Chhattisgarh joint venture partners are currently awaiting
    approval from the Government of India's Forestry Department to
    undertake comprehensive, large scale kimberlite evaluation
    programmes, including drilling, trenching and bulk sampling.
    Preliminary marking out of the surface of the Behradih kimberlite has
    recently commenced for gridding and clearing to permit drilling and
    surface excavation. An Indian fabrication contractor has been awarded
    the contract to construct a Plietz jig with a nominal capacity of 10
    tonnes per day, which will initially be used to bulk sample
    kimberlite until the design of a more sophisticated Dense Media
    Separation ("DMS") plant is finalized. The Plietz jig will enable the
    joint venture partners to obtain more detailed information about
    Behradih and the other pipes.
    The joint venture's nearby Mainpur laboratory facility is now
    operational and approximately 150 samples have been processed over a
    recently installed Wilfley table and subjected to TBE separation
    since the resumption of this field season's exploration programmes.
    These concentrates were delivered to the local laboratories earlier
    this week. A further 500+ regional steam sediment and loam samples
    have been collected and are awaiting treatment in Mainpur before
    being sent to Johannesburg, RSA. A number of the samples collected
    this season are follow-up stream sediment samples obtained from
    priority targets generated from the initial orientation sampling
    programme.
    The expedited processing and analytical methods currently being
    employed by the joint venture partners are designed to more rapidly
    trace the high interest indicator mineral dispersion trails to their
    possible kimberlitic sources. During the coming months, known and
    newly discovered kimberlites will be treated through the Plietz jig
    to more accurately evaluate their potential. This data will be
    collated and used for the final design criteria of the DMS plant.
    The fine diamond and heavy mineral results obtained to date for
    Behradih are extremely encouraging, although it should be noted that
    the overall combined sample sizes are relatively small. Additional
    work will be conducted during the current field season at Behradih
    and other locations in the Raipur kimberlite field to more accurately
    determine their prospectivity and economic potential.
    The acquisition of drilling and bulk sampling equipment is high on
    the joint venture partners' priority list to advance the project as
    expeditiously as possible throughout the remainder of this field
    season (+/-7 months). Detailed kimberlite evaluation programmes
    combined with the regional airborne geophysical survey, regional
    stream and loam sampling programme, on-site sample processing and
    ground geophysical surveys to delineate new kimberlite sources will
    ensure that rapid progress with the exploration and development of
    the highly prospective cratonic D-7 block will be accomplished before
    the end of the current season.
