Interim Management Statement

Gem Diamonds Limited 23 April 2008 GEM DIAMONDS LIMITED ('Gem Diamonds' or 'the Company') INTERIM MANAGEMENT STATEMENT FOR THE FIRST QUARTER ENDED 31 MARCH 2008 This Interim Management Statement is Gem Diamonds' first and reflects the Company's performance in the first quarter of the 2008 financial year. After a year of solid progress in 2007, Q108 has seen continued remarkable diamond prices achieved across all its producing mines. Highlights - Strong rough diamond sales across all three mines with record prices achieved - Q108 carats sold of 156 438 - Q108 diamond sales revenue of US$56.1 million - Beneficiation trials successful with significant additional margin capture - average price per carat of US$74 000 achieved - Letseng second plant final commissioning commenced and first ore processed and diamonds recovered - Encouraging grades from new sample area in the CAR 1 Lesotho Gem Diamonds holds a 70% shareholding in Letseng Diamonds (Pty) Ltd ('Letseng') in partnership with the Government of the Kingdom of Lesotho which owns the remaining 30%. 1.1 Production Hard rock mining commenced in the Main Pipe in December 2007. Accordingly in Q108 ore was available from three sources - Main and Satellite Pipes as well as Main Pipe stockpile. To ensure optimal production levels, ore from all three sources was blended and treated in Q108. Q108 Q107 % Change Ore mined and processed - Letseng Diamonds 699 456 677 208 3% Carats produced - Letseng Diamonds 13 268 15 956 -17% Ore mined and processed - Alluvial Ventures 506 503 208 527 143% Carats produced - Alluvial Ventures 5 603 2 152 160% 1.2 Diamond Sales Q108 Q107 % % % Change Change Change Cts Total Achieved Cts Total Achieved Cts Total Achieved sold tender US$/ct sold tender US$/ct sold tender US$/ct value value value US$ US$ US$ millions millions millions Letseng 8 190 20.50 2 502.71 16 841 39.0 2 315 -51% -47% 8% Diamonds Alluvial 2 731 2.56 936 947 0.4 472 188% 540% 98% Ventures Total 10 921 23.05 2 111 17 788 39.4 2 217 -39% -41% -5% In Q108 two tenders took place, versus three in the comparative period. Prices achieved for goods sold from the Main Pipe, Satellite Pipe and Main Pipe stockpile are significantly ahead of forecast for run of mine production. 1.3 Beneficiation Between July and November 2007, seven D colour diamonds were extracted from production for polishing in Antwerp by Matrix Diamond Technology using their proprietary diamond technology. Six of these diamonds totalling 137 carats were polished into 45.7 carats, of which 41.6 carats were sold for US$3.1 million at an average price of US$74 000 per carat. The seventh highly complex rough diamond, weighing 129 carats has been polished into 34.5 carats and the polished stones will be sold in Q208. 1.4 Expansion and Development Final commissioning of the second plant began in late March with 700 tonnes of ore treated and 12.8 carats recovered. The project is on track to achieve full production by the end of the Q208. 1.5 Power Supply Letseng Diamonds is supplied with power by the Lesotho Electricity Corporation ('LEC') who in turn source some of this power from the South African parastatal ESKOM. Letseng Diamonds has received permission to draw more power in order to run the second plant. The line that will feed this increased demand has been, and will continue to be, subjected to ESKOM load shedding. To date there has been minimal impact to production caused by the load shedding due to: - the short periods of load shedding; - the mine having managed to re-schedule maintenance periods to coincide with the load shedding; and - the second plant not yet running at full capacity. To minimise the possible impact of load shedding, Letseng is making arrangements to install standby generating capacity sufficient to run the whole mine. Letseng will develop plans in conjunction with the LEC to upgrade an alternate line from the LEC's hydro-electricity plant to secure an uninterrupted supply at the increased demand level. 2 Australia Gem Diamonds completed the compulsory acquisition process of all shares and options in Kimberley Diamond Company ('Kimberley Diamonds') during Q108. The new Managing Director, Alistair Croll, took up his appointment at the end of February and at the first Kimberley Diamonds Board meeting, held at the end of March 2008, the Board was reconstituted accordingly. 2.1 Production Mining into the wet season (three months from mid December through mid March) continued in Q108 notwithstanding past practices of only processing ore stockpiled during the year. The tonnage throughputs for Q108 are reflected in the table below and show (allowing for wet season vagaries) that the good progress achieved in late 2007 has continued in 2008. High processing rates achieved in December and January combined with limited waste stripping in the months leading up to Gem Diamonds acquisition, has resulted in lower stockpile volumes and reduced stripped reserves. The combined impact is that with the lack of flexibility to mine to average grade, lower average grades have been achieved. 2007 2008 Oct Nov Dec Jan Feb Mar Ore mined and 0.58 0.65 0.65 0.69 0.44 0.53 processed (mt) Cts Produced 46 500 50 400 42 700 45 700 22 400 30 600 Grade cpht 8.0 7.7 6.5 6.6 5.1 5.8 2.2 Diamond Sales Q108 Q107 % % % Change Change Change Cts Total Achieved Cts Total tender Achieved Cts Total Achieved sold tender US$/ct sold value US$/ct sold tender US$/ct value value US$ US$ millions US$ millions millions 130 476 28.1 216 158 600 20.2 127 -18% 39% 70% 2.3 Expansion and Development On acquisition, Ellendale had a processing capacity of 8mtpa but were mining at 60% of this capacity. This processing capacity has subsequently been increased to 8.5mtpa and will be further enhanced to 10.5mtpa. Tonnes mined and processed in 2008 and 2009 will increase accordingly. Extended maintenance work was undertaken on the E4 South plant in February to enable improved throughput volumes planned for the drier months. Capital work on the two main plants at E4 and E9 continued as part of the throughput improvement programmes. A third mining fleet has been commissioned to facilitate higher waste stripping rates and maintain ore generating capacity at the required grade. 3 Indonesia BDI Mining owns 80% of the Cempaka alluvial diamond mine in South Kalimantan, Indonesia in partnership with the Government of Indonesia which owns the remaining 20%. 3.1 Production Mining in Q108 was predominantly in the Cempaka channel as opposed to the Danau Seran channel in the comparative period. Production for Q108 was as follows: Q108 Q107 % Change Gravel mined and treated (mt) 0.54 0.13 315% Overburden stripped (mt) 1.82 0.74 146% Strip ratio 3.35 5.88 - Carats recovered 6 004 4 845 24% Grade (cpht) 1.10 3.83 -71% Au/Pt conc produced (kg) 4.5 3.1 45% The build up of gravel treated continued in the first two months of Q108 culminating in the achievement for the first time of the targeted 216 000 tonnes in February 2008. The recovered grade was lower than expected but improved grades are anticipated in the areas being mined for the balance of 2008. Rainfall led to widespread flooding and adversely affected production in March 2008. The mining block in Danau Seran channel was flooded and will take several weeks to dewater. The mining face in the Cempaka channel was less severely affected and will be available earlier than the Danau Seran block. 3.2 Sales Q108 Q107 % % % Change Change Change Cts Total Achieved Cts Total Achieved Cts Total Achieved sold tender US$/ct sold tender US$/ct sold tender US$/ct value value value US$ US$ US$ millions millions millions 15 041 5.0 331 7 661 1.7 225 96% 194% 47% 3.3 Expansion and Development A DMS plant has been procured for Cempaka and will be delivered in Q208. This will enhance the mine's recovery process. The delivery of the mining fleet for the expanded production and conversion from contactor to owner mining is largely complete. 4 Botswana Subsequent to the submission of a Mining License Application in H207, the Retention License was extended to the end of August 2008 to allow for the Feasibility Study and the Social and Environmental Impact Assessment ('SEIA') to be completed. The SEIA continued with the holding of numerous Public Participation meetings with interested and affected communities. The meetings were positive with all communities consulted indicating their support for the mine. These studies resulted in the Scoping Report being submitted to the Government in February. The SEIA process is on target and the approval is expected in H208. Thereafter the Section 51 negotiations with the Government of Botswana, which will determine the awarding and key terms of a mining license, are expected to commence. 5 DRC Gem Diamonds has interests in three projects in the Democratic Republic of the Congo ('DRC') at Mbelenge, Lubembe and Longatshimo. These interests are held via a number of companies in which Gem Diamonds has between an 80% and 100% shareholding. 5.1 Mbelenge With the low grades returned in the latter part of 2007 from the terrace gravels, sample trenches transverse to the old river flow direction were excavated to refine the geological model. These transverse trenches have been sampled and confirm the overall low grades in this area. A programme has been designed to sample the gravel deposits of the modern river system and dredges were transferred from Lubembe for this purpose. 5.1.1 Production and Sampling Production and sampling results for Q108 were as follows: River terraces Actual Overburden stripped m3 278 048 Gravel mined : m3 48 630 Gravel treated : m3 49 328 Carats recovered 6 208 Grade : cts/ m3 0.13 River Dredging Actual Gravel mined : tonnes 19.79 Gravel treated : tonnes 19.79 Carats recovered 64.35 Grade : cts/ tonne 3.25 5.1.2 Diamond Sales Two parcels of Mbelenge diamonds totalling 10 699 carats were sold in Antwerp for an average price of US$86 per carat in Q108. 5.1.3 Expansion and Development Further sampling by way of dredging will continue into the dry season and will provide an indication of river grades. The construction and sampling of paddocks in the Kasai River will provide additional information and sampling of the terraces in the north of the project area is also planned. The further development of Mbelenge will be reviewed on receipt of the sampling information. 5.2 Lubembe Sampling at Lubembe in Q108 continued with the remaining dredges and was predominantly resource development focused. 5.2.1 Sampling Resource development through bathymetric mapping and sampling was undertaken with 2 255 carats recovered at a grade of 13.43 cts/tonne recorded. Seasonal flood conditions delayed the treatment of other samples taken, which have been stockpiled for treatment in early Q208. Actual Gravel mined : (tonnes) 242.43 Gravel treated : (tonnes) 167.95 Carats recovered 2 255.25 Grade : (cpt) 13.43 5.2.2 Diamond Sales In January 2008 a parcel of 4 608 carats was sold in Antwerp for US$82 per carat, in line with expectations. 5.2.3 Expansion and development 5.2.3.1 Alluvial Sporadic high grade gravel pockets were encountered at Lubembe and diamonds have been successfully recovered. Accordingly, an appropriate mining technique to exploit this resource is being evaluated. In the interim the dredging programme at Lubembe will be suspended to allow the dredge units to be deployed at Mbelenge. 5.2.3.2 Kimberlite No kimberlite drilling took place in Q108. The portable drilling rig is being tested after which the remaining 22 anomalies will be drilled. 5.3 Longatshimo Sampling results during the latter part of 2007 were less encouraging than the initial programme. Plans for trial mining are under review. Resource definition of river terraces and floodplain settings is ongoing in the Longatshimo area through systematic field mapping, reconnaissance pitting and limited sampling. The geophysical anomalies that were generated by the helimag survey that was conducted recently in the Longatshimo area are being investigated. A further four anomalies were drilled in Q108, with no kimberlites intersected. Further surveying has identified four anomalies, bringing the total outstanding anomalies at Longatshimo to 14. 6 CAR Gem Diamonds holds a 75% interest in Gem Diamonds Centrafrique SA, in partnership with the Government of the CAR which holds the remaining 25%. Gem Diamond Centrafrique holds exclusive exploration and mining rights to the 800km2 Mambere Concession. 6.1 South Mambere: Sample Results Bulk sampling of terrace gravels in the le Buckle area was completed in December 2007 and from January 2008 sampling and exploration work was in the modern day Mambere River. Grades of more than 70 cpht have been recovered from the bottom gravels. However, the 'run of mine' recovered grades in February and March was 20 cpht. The diamonds are estimated to be worth US$140 per carat. Work to determine the extent of the resource will continue throughout 2008. 6.2 North Mambere: Exploration Strong historical production and grades of 15 to 30 cpht are recorded from the northern part of the concession from the Mambere River tributary gravels. Quickbird satellite imagery will be used to direct the geological exploration programme in this area during Q208. Past and present mining activity in the area, undertaken by local artisans, is being evaluated in terms of overburden thickness, grade, volume and stone size. 7 Angola A Cooperation Agreement was signed in January 2007 between Gem Diamonds and Avantis Angola Inc ('Avantis') with respect to a feasibility study to be conducted on the known Chiri kimberlite in the Lunda Sul Province of Angola in which Avantis have a 25% interest. An Option Agreement whereby Gem Diamonds can acquire an effective 11.25% interest in Chiri from Avantis was signed at the same time. Negotiations surrounding the Cooperation Agreement continued through most of 2007 with an addendum to the Cooperation Agreement being signed in December providing for an acceleration of activities with defined milestones for particular activities and an effective start date of January 2008. A camp has been established and technical personnel are on site. Final procurement of equipment was completed in Q108. The 10tph DMS sampling plant and large diameter drilling are in transit to site and expected in Q208. Contracts have been signed for the site preparation, civil engineering works and erection of the sampling plant, management of field operations and for lease of the earthmoving equipment for the bulk sampling programme.
