Resource Update

African Consolidated Resources Plc 07 August 2007 African Consolidated Resources Plc The Board of African Consolidated Resources plc ('ACR' or the 'Company'), the AIM listed exploration company focused on Zimbabwe, is pleased to announce a resource update together with further information on the Marange diamond deposit application and a grant of options. Resource Update Resource estimates have been carried out following reverse circulation ('RC') drilling programmes at the Company's two lead gold projects in the Midlands district of Zimbabwe, Concession Hill at the Pickstone-Peerless project and the Giant Mine project 30km to the north. No further drilling has been carried out on the Peerless Mine area since the initial resource definition. Data compilation at the One Step project has identified significant mineralised trends for drill testing. Current resources as estimated according to the methodology of the Company's consultants, SRK Consulting ('SRK') stand at 14.9mt at 1.7g/t for 813,000 oz. (SRK methodology has not been applied to the Pickstone Peerless mine dumps and to underground ore blocks in the Pickstone mine; these were calculated by previous operators to JORC standards and reviewed by SRK and are included in the total estimate). This compares with 14.1mt @ 1.8 g/t for 820,500 oz as previously reported in June 2006. Concession Hill (Pickstone) To date, 107 RC holes totalling over 12,500m of drilling have been completed on Concession Hill which lies above the historical Pickstone underground mine. Drilling is spaced at 80m along strike, and generally 30m down the dip surface of the deposit. Drilling tested the deposit to approximately 150m below surface. Resources on admission to AIM in June 2006 stood at 180,000 Inferred oz from ACR RC drilling of the crown pillar above the old workings, and a further 31,500 ' legacy' ounces within remnant underground ore blocks in levels 2 and 3 of the old mine as estimated by previous operators in the 1990's. All resources estimated for Peerless and Concession were classified as Inferred except the legacy underground ore blocks which were Measured. At a 0.5 g/t cut-off, the resources were: Resource at June 2006 Deposit Tonnes Grade Ounces Peerless 4,600,000 1.4 210,000 Concession 3,200,000 1.8 180,000 Concession Legacy Resource 205,000 4.8 31,500 TOTAL 8,005,000 1.6 421,500 SRK have estimated a revised resource at Concession Hill of 4.8 million tonnes at 1.5 g/t for 240,000 oz. As a conservative measure, and in consultation with SRK, ACR has decided not to report the legacy resource as a separate entity, and instead assume that this material is already included in the Concession resource estimated from the drilling. Some of the deeper ACR drilling overlaps legacy ore blocks. ACR intends to carry out its own study of the economic potential of the remnant ore in the old workings, which extend to a depth of 750m below surface. Historical production from the Pickstone Mine beneath Concession Hill was approximately 500,000 oz. The results of the new Concession estimate are summarised in the following table: Inferred Resource at July 2007 Deposit Tonnes Grade Ounces Peerless 4,600,000 1.4 210,000 Concession 4,800,000 1.5 240,000 TOTAL 9,400,000 1.5 450,000 Additional resources within the Pickstone-Peerless dumps are summarised below. Giant Mine A total of 13,525m of RC drilling has been completed at the Giant Mine since June 2006. Drilling is generally at 50m spacing along strike, and approximately 30m down the dip surface. Drilling tested the deposit to approx 100-150m below surface, which was the maximum depth capability of the RC rigs available. A hard mineralised diorite at the south end of the deposit requires diamond drilling to penetrate the full depth of mineralisation, and elsewhere dip extensions below 100-150m depth will require additional drilling. Old mine plans indicate the orebodies were well developed down to about 210m below surface. SRK was contracted to undertake an interim study on the drilling completed to date. An existing JORC Resource of 4.9 mt @ 2.1 g/t for 336,000 oz (Comprising 3.5mt @ 2.1 g/t for 230,000 oz Indicated and 1.5mt @ 2.2 g/t for 106,000 oz Inferred) was estimated in 1997 by Global Mining Services (GMS) of Perth, Western Australia, from 107 RC drill holes completed by Cambrian Resources. The current drilling programme was planned to test the mineralisation along strike and to depth. From the drilling done by ACR, and the 1997 database compiled by Cambrian Resources N.L., SRK carried out an interim resource estimate for the Giant Mine. At a 1 g/t cut-off (the same cut-off used for the 1997 model), SRK estimated an Inferred Resource of 4.4 Mt @ 2.2 g/t for 300,000 oz. The decrease in ounces compared to the previous estimate occurred because: 1. ACR has interpreted a structurally-controlled model for mineralization (rather than the lithologically-controlled model used by GMS). Although the volume of the mineralized domain has decreased, the improved understanding of the orebody orientation and mineralisation controls will be of great benefit in future exploration. 2. ACR and SRK have been more conservative than GMS in extrapolating mineralization away from the limits of the drilling. The mineralized envelope used by SRK is generally projected no more than 30m from the outermost drill holes (30m is the typical east-west spacing between drill holes). GMS extrapolated their Resource model up to 70m away from the extent of the drilling. The original GMS model was classified as 70/30 Indicated/Inferred, but SRK considers that the entire resource should be classified as Inferred, based on geostatistical parameters, uncertainties about the position and extent of old underground workings throughout the orebody, and the limited set of samples available for estimating density. SRK has advised ACR on a drilling programme of 3500m to test possible extensions to the orebody to a target depth of 150-200m below surface. The additional drilling will also aim to infill gaps and increase confidence in the resource estimate. Much of this will be diamond drilling, which will provide valuable additional data on structure, specific gravity and rock strength factors. This programme will commence as soon as a suitable rig becomes available.

Diamond drilling by Rio Tinto plc in the mid-1990's returned a best intercept of 24m @ 2.6 g/t in the centre of lease, with over 400m of strike un-drilled to the north. ACR has acquired 24 new claims at One Step and the consolidated holdings now extend discontinuously over 4km of mineralised trend. The historical diamond drillhole intercepts on ACR's claims have been compiled and re-calculated using the weighted-average method and are listed below. Significant results include: Hole ID Easting Northing From (m) Width (m) Wt. Av.

ACR intends to infill the mineralised trend over about 600m of strike with Reverse Circulation drilling as soon as a rig is available. Sampling of two tailings dumps is also underway. Dumps In addition, results from sampling of tailings dumps at the Giant Mine and the One Step project near Kadoma have incurred logistically related assay delays and so will only become available later in August. Marange Diamond Title Further to the announcement on 6 July 2007, the Company still awaits a date in the Zimbabwe High Court for a hearing to obtain an order confirming that its claim over the Marange diamond deposit is valid. The Company expects that the case will be heard prior to the end of 2007 although it has no certain date or even reliable estimate as to when the matter will be heard. The Company's legal advice that its claim to title should be successful remains unchanged. As announced on 2nd July 2007 the Company continues its dialogue with relevant parties with a view to possibly agreeing a joint venture over the deposit prior to the High Court hearing. The Company would like to re-iterate that at this point there can be no certainty as to the timing or outcome of the civil action or any agreement on the ownership and operations of the Marange deposit prior to that action. Further statements will be made to update the market in due course. Grant of Options The Company has granted 4,000,000 options over new Ordinary Shares of 1p each in the Company exercisable at 14.5p per share from 30 June 2008 to 29 June 2011. These options have been granted to an employee trust for a broad range of staff and independent consultants working for the Company mainly in Zimbabwe. The trust is a discretionary one and the trustee is a wholly owned subsidiary of the Company, which through its Remuneration Committee, will advise on allocation of options. Options may be allocated to specific beneficiaries (excluding directors of the Company) as reward for performance or for value added.
