This is a substantial increase in the number of kimberlites (38) as previously reported in the 31 March quarterly report and illustrates the solid progress being made on a regular basis. The third core drill rig which arrived on site during the quarter has accelerated the exploration programme significantly and core drilling now totals 26,000 metres on 190 holes. Drilling has also commenced in the north east of the project area where 4 kimberlites have been identified. The importance of this accelerated drilling programme is evident when it is considered that of the total 249 magnetic anomalies, 60 have now been drilled and a total of 50 have been confirmed as kimberlitic. This success rate continues to surpass the norms for global kimberlite exploration. The large diameter drill rig has arrived in Luanda and will be operational on site at Alto Cuilo in August when it will commence drilling on the targets selected for mini bulk sampling. The 10 tonne per hour mobile dense media separation ('DMS') sample plant and drill rig had been delayed due to component delivery constraints, however the drill rig was delivered 4 weeks ahead of the revised schedule and the DMS plant is on schedule to begin processing by September 2006. The drill rig will initially stockpile 200 tonne bulk samples from the most prospective anomalies, and the plant, which is a custom made closed circuit unit designed specifically for kimberlite bulk sampling, will start treating these once it is commissioned. Analysis of kimberlite core from 11 of the kimberlites identified so far delivered some highly encouraging diamond indicator mineral results. Key data revealed was as below: (i) Chrome diopside analysis returned a favourable mantle geotherm, indicating that there is a high probability that the kimberlite will have sampled material derived from the earth's diamond stability field at a temperature favourable for the formation of diamonds; (ii) Peridotitic garnet analysis revealed pressure-temperature conditions compatible with the presence of diamond stability field G10 garnets derived from well within the diamond stability field; and (iii) Eclogitic garnet analysis also gave excellent results, with an abundance of high sodium eclogitic garnets in some samples, further increasing the potential for quality diamondiferous kimberlite. Diamond indicator mineral chemistry is crucial in terms of assessing a kimberlite's likelihood of hosting diamonds. It is accepted by the world's kimberlite experts that the higher the count of the acknowledged diamond stability field indicators, the higher the likelihood of the kimberlite hosting economic grades. The results at Alto Cuilo are very exciting and are comparable to other economic kimberlite deposits around the world. Alluvial Exploration The alluvial pitting and trenching programme continues in order to further evaluate the potential for economically viable alluvial deposits, with 507 pits and 7 trenches having been completed. Trial mining on a section of the Luangue river is due to commence shortly using the existing 65 tonne per hour DMS plant and earthmoving equipment. It is expected that the trial mining programme will continue for 24 months in the area of specific alluvial interest. It is believed that apart from production of diamonds, invaluable exploration information will also be gleaned from this alluvial programme. BHP Billiton Joint Venture As at 30 June 2006, BHP Billiton had advanced funding of US$22.8 million (31 March 2006: US$16.1 million) to Petra Diamonds Alto Cuilo Limited in respect of exploration at Alto Cuilo. Xceldiam - Strategic Cooperation On 30 May 2006 Petra entered into a Strategic Cooperation Agreement with Xceldiam Limited with regards to Project Luangue. Petra notes with interest the early drilling success at Project Luangue as announced on 25 July. Core drilling at Project Luangue returned excellent first results, with drilling on the first target intersecting kimberlite. This news supports Petra's belief that Project Luangue may host kimberlite geology similar to that of Project Alto Cuilo and Petra looks forward to further developments from Project Luangue. Botswana, Kalahari Diamonds The exploration field effort has gathered momentum with the change in focus from primarily large kimberlites (> 20 hectares), to also include smaller kimberlites (approx 10 hectares) that would not necessarily be detectable by Falcon airborne gravity under deep (> 50 metres) Kalahari cover. Gope Geophysical targets from Xcalibur and Falcon surveys in the Gope area have been prioritised by their geophysical response compared to the known kimberlites from the orientation survey conducted last quarter, and their spatial relationship compared to the known kimberlitic indicator minerals ('KIM') anomaly that has been compiled from data collected by previous exploration companies. This KIM halo is offset from the known Gope kimberlites by at least 12 kilometres, and is therefore probably not related to the known bodies, implying that there could be potentially large, undiscovered kimberlites in the Gope field. A total of 41 targets have been investigated in the Gope area by follow up ground geophysics this quarter, identifying a number of co-incident gravity and magnetic anomalies with similar characteristics to known Gope kimberlites within, and directly adjacent to, the KIM halo. A drilling program to test these anomalies will commence in the latter part of this year. Orapa South Fieldwork has commenced in the northern portions of our Orapa South area, following up targets identified from the re-gridded Falcon magnetic and gravity data. A total of 13 anomalies have been investigated by ground follow-up geophysics, starting with targets in the north of the Orapa South flight blocks - directly south of the Orapa kimberlite field, and some short distance away from AK6, currently being evaluated by De Beers and African Diamonds. This locality has a Kalahari sand cover of up to 30 metres and thus a dedicated KIM survey will also be undertaken, so as to assist in selection and interpretation of anomalies. Orapa North A total of 9 anomalies selected from ground and airborne magnetic and ground gravity data were investigated by trenching in the Orapa North area. Trenching was chosen as the preferred method of ground follow-up as Kalahari cover is negligible, and calcrete horizons seldom exceed 3 metres in thickness. All trenches (but one) intersected bedrock (Stomberg Basalts in all cases). Samples were taken from all trenches for heavy mineral extraction at Petra's preparation laboratory at Swartruggens, South Africa. Mabutsane / Thswaane A ground gravity survey was carried out over the large (diameter 1.5 kilometre) gravity-only anomaly that was drilled during the quarter to December 2005. This was done as specific gravity determinations on cuttings recovered from this hole failed to explain the cause of the anomaly and to facilitate geophysical modelling of the causative body. Modelling was carried out by the BHP Billiton Falcon unit in Melbourne, and the 3D SolidEarthTM model produced indicates a large pipe-like 'unit' extending from about 200 metres depth to about 1800 metres depth. The top of this unit is deeply concave and was not penetrated by the borehole drilled in 2005. If a kimberlite model is to be assumed, the model suggests about 4 lobes of low density material, coalescing at depth. One may expect these lobes to form one very large crater, which, given absence of KIM's in the drill hole and surrounds, could have been infilled by late Karoo group rocks and later, covered again by the Kalahari beds seen today. A decision will be made this quarter as to whether to deepen the existing hole in the centre of the anomaly, or to drill on the edge of the anomaly where the causative body could be closer to surface. The final Tshwaane data has been received from BHP Billiton and anomalies are in the process of being selected for ground follow-up work. Sierra Leone - Kono Project The plant was commissioned and first diamonds recovered from the Kono project on schedule in June 2006. The recovery of 5.6 carats of diamonds, including a 1.4 carat stone, from the small amount of material processed was highly encouraging. Sinking of the production shafts is on track and we look forward to further developments at Kono over the coming months. Infrastructure Development Since the last quarterly report the construction of the production plant at the central base camp in Yengema Village was completed on schedule in May 06. The plant was successfully commissioned in early June 2006. The treatment of samples then commenced, with a very positive macro and micro diamond recovery rate on the grease table. Sample Treatment As at 30 June, 44 diamonds totaling 5.6 carats had been recovered, the largest being a stone of 1.4 carats. The samples processed to date comprise mixed and diluted material from exploration and shaft sinking operations. The results, whilst very encouraging, are not large enough to arrive at any representative grade. Sample treatment is ongoing. Exploration Development Shaft sinking operations are proceeding well and a sound infrastructure is in place alongside the DMS plant. Two shafts, both of which are on kimberlite fissure, are in progress with the deepest (Black Rock) being at a depth of 13.5 metres and the second (Lost Shaft) at a depth of 9 metres. The shafts will be sunk to a depth of around 30 metres before stopes are prepared to access production test tons of fissure. Exploration trenching uncovered two very promising diamondiferous fissure strikes at Levuma on the Lion 5 dyke extensions and Yendema south west of the original Lion 2 dyke strike. Exploration trenching is underway at Bundofulahan, a fissure strike north of Lion 4. At Bardu, a south-west extension of the Lion 5 dyke extension also exists, with exploration results expected by September 2006. With the multiplicity of diamondiferous fissures available and the information at hand, the short term bulk sampling and exploration focus was reviewed in order to continuously improve the efficiency and effectiveness of the project. The short term objectives for the next six months are as follows: • to aggressively step up the sinking operations at Black Rock and Lost Shaft in order to access production test tons of diamondiferous fissures by mid October 2006; • the roll out of three test shafts up to a depth of 20 metres in order to access mini bulk sample test tons on three of the most promising diamondiferous fissure strikes which were recently uncovered during exploration trenching; and • to maintain the aggressive exploration activities using numerous rolling exploration trenches in order to uncover additional diamondiferous fissure strikes and to create a better understanding of the characteristics of the diamondiferous fissures available. The shaft sinking programme will be aggressively stepped up by the implementation of a second shift supported by additional shaft sinking specialists from Petra's South African operations. The aim is to phase over from shaft sinking to stoping activities as soon as possible in order to gain access to production test tons in the quarter to December. This is necessary in order to accurately determine the grade of the deposit and to get a sample of diamonds large enough to ascertain the quality of the diamonds by December 2006. The roll out of three test shafts on the most promising diamondiferous dyke strikes recently uncovered by exploration trenching will enable Petra to gain access to mini-bulk samples in order to identify and determine the most promising kimberlite dykes. If the results are favourable the test shafts could be seamlessly converted into bulk sampling shafts. The aggressive rolling exploration trenching method has proven to be a very effective and cost efficient method of quickly exploring the fissures surrounding the central base camp and processing infrastructure. It is envisaged that six additional trenches will be opened, the fissure penetrated and the result evaluated by December 2006. The integrated result of the above mentioned activities will provide Petra with a better understanding of the diamondiferous fissures available, their potential and the project strategy ahead. South Africa The combined operations produced a total of 43,378 carats for the quarter. As noted in the previous quarterly report dated 30 April 2006, the production build-up was affected by severe flooding following the unusually high rainfall experienced in South Africa for the period mid-February to mid-April in conjunction with power interruptions due to these unusual weather conditions. Star Mine A total of 7,964 ROM fissure tonnes was delivered to the plant for 2,788 carats, yielding a grade of 35 carats per hundred tonnes ('cpht') for the quarter. In addition 10,051 tonnes of tailings were processed for 1,105 carats. This resulted in a total of 3,893 carats for the combined Star operations. During the quarter the sealing and support of the 1.4 diameter raise-bore ventilation shaft was completed. The final shaft inspection indicated that additional support was required in the area where the shaft intersects the shale formations and this was completed by the contractor during July. The required return-ventilation airways have been completed on 13 level and ventilation districts in the Burns operational sections will be established during the first quarter of FY 2007 to improve the underground ventilation conditions. The improved conditions will assist in increasing production from underground operations. In the Wynandsfontein section the 3 new panels on 15 level continue to produce well. The difficult 10 level haulage is contributing to hauling problems and an increase in loco maintenance. Replacement of the 10 level haulage by the 14 level haulage has been rescheduled and will be commissioned by June 2007 In the Burns section, all 15 level panels are producing well. Further, the primary development on this level will be fast tracked (because of better ventilation) to establish multiple production stopes to assist the production build-up in the 2nd quarter of FY 2007. The three panels being mined in traditional fashion on 14 level east are still producing well and with the improved ventilation conditions additional production from this historically high grade area is anticipated. With the raise-bore shaft now completed the deepening of the main shaft between 12 and 14 levels will be fast-tracked so as to reduce ore handling problems. The plant front-end washing and crushing section was commissioned during the quarter. Helam Mine A total of 31,060 ROM fissure tonnes was delivered to the plant for 26,460 carats, yielding a grade of 85 cpht for the quarter. In addition 2,153 carats were produced from the tailings operation. This resulted in a total of 28,613 carats for the combined operation. The slyping and equipping of John Main Shaft to 20 level and the pilot raising of the main shaft between 21 and 20 level was completed. The break-away from the west-sub shaft to the 22 level main shaft station positioning commenced during the quarter. The Second Lease incline project has progressed well with the loading arrangement on 17 level now complete. Production from 17 level stope and the required development waste to establish multiple stopes on this level, which has up to now been trammed along the traditional route, will henceforth be hoisted via this route to John Main Shaft. This will relieve pressure on the east sub vertical shaft and allow more total tons to be hoisted. The John Main Shaft skip hoisting and loading arrangements were completed and commissioned. This additional hoisting capacity will be utilized for production from Second Lease and waste development to open-up required production resources. At Edward Shaft the establishment of 25 level is progressing well. On surface, the manufacturing of the ore handling upgrade system (similar to John Shaft) has been completed and will be commissioned shortly. This will result in a further reduction of labour cost. Sedibeng Mine A total of 33,271 ROM fissure tonnes was delivered from the mining operation, which yielded 8,318 carats at a ROM grade of 25 cpht. In addition 2,554 carats were produced from the Dancarl tailings operation at a grade in excess of 7 cpht. This resulted in a total of 10,872 carats for the combined operation. At Sedibeng production is going well but was beneath original call due to difficult ground conditions on 23 level that has delayed proper stope development by nine months. However, these bad conditions have now been negotiated and stope establishment is now continuing as planned. The deepening of the west sub shaft to 24 level is progressing well and is eight metres short of level. The 20 South drive into the Dancarl section is now 50 metres short of being vertically beneath Dancarl main shaft. The planning to initiate a raise-bore holing to the bottom of Dancarl main shaft is progressing as scheduled. Capex has been approved for the construction of a complete new DMS diamond recovery plant incorporating all modifications that will be of benefit to operations. This plant will cater for all production (present and future) from the Sedibeng mining and tailings. It is anticipated that when this plant is commissioned in the quarter to March 2007 it will result in a dramatic reduction in operating cost and a significant improvement in diamond security.
