Proposed Acquisition

Goldstone Resources Ltd 03 April 2007 GOLDSTONE RESOURCES LIMITED PROPOSED ACQUISTION OF AN INTEREST IN THE SWARTDORING DIAMOND PROJECT The Directors of GoldStone Resources ('GoldStone' or the 'Company') announce that the Company has conditionally agreed to acquire a 70 per cent. interest in Xanadu Mining (Pty) Limited ('Xanadu Mining') from GeoQuest Holdings Limited (' GeoQuest') (the 'Acquisition'). Xanadu Mining has, through its wholly-owned subsidiaries GrindStone Mining (Pty) Limited ('GrindStone Mining') and Multi-Direct Mining (Pty) Limited (' Multi-Direct Mining'), filed applications for prospecting rights over the Swartdoring Diamond Project, all of which have been accepted by the Department of Minerals and Energy ('DME') in the Republic of South Africa. Under the acquisition agreement dated 2 April 2007 (the 'Acquisition Agreement'), GoldStone has conditionally agreed to acquire a 70 per cent. interest in Xanadu Mining from GeoQuest in consideration of the issue of 50,640,000 consideration shares ('Consideration Shares'). At the mid-market price of 1.1 pence per share at the close of business on 2 April 2007, the Consideration Shares have a value of £557,040. GeoQuest holds 40,000,000 ordinary shares of 1p each in the Company (the ' Ordinary Shares'), representing approximately 30.6 per cent. of the existing Ordinary Shares. In addition, each of the Directors has an interest in the share capital of GeoQuest which, in aggregate, represent 32.2 per cent. of the share capital of GeoQuest. The Acquisition is therefore classified as a related party transaction under the AIM Rules. A related party transaction for an AIM company does not ordinarily require the approval of shareholders, however, the Directors considered it appropriate in this case. The Acquisition is conditional, inter alia, on the passing of a resolution at an extraordinary general meeting to be held on 19 April 2007 (the 'EGM'). A circular will be sent to shareholders today including notice of the EGM (the ' Circular'). Sir Michael Oliver, the independent director, having consulted with Hanson Westhouse Limited, the Company's nominated adviser, considers the Acquisition to be in the best interests of the Company and shareholders as a whole. Background to the Acquisition GoldStone was admitted to AIM in March 2004 with the objective of continuing the exploration of two areas in Guyana in order to find economically mineable gold palaeoplacers. Having undertaken an extensive exploration and evaluation programme, the Company successfully discovered 21 palaeoplacers exhibiting similar geological characteristics to the Witwatersrand, an area in South Africa from which an estimated 50,000 tonnes of gold, or more than 40 per cent. of total worldwide gold production, has been derived. While a number of the palaeoplacers were found to contain anomalous quantities of gold, the low tenor of the intersections made during the drilling programme led to the Directors concluding that the likelihood of finding economical grades was remote. Furthermore the Directors felt that high drilling costs made continued detailed exploration of the palaeoplacers prohibitive. A decision was taken in August 2006 to cease all gold exploration in Guyana. A lateritic bauxite deposit is also located within permit areas held by the Company. In September 2005, GoldStone entered into an option agreement with BHP Billiton ('BHPB') over the bauxite interests. BHPB launched an initial programme which confirmed the deposits previously identified by GoldStone. Further, more detailed sampling is planned. In September 2006, BHPB paid to GoldStone the fee of US$100,000 which is required to maintain the option until 6 June 2007. In the event that BHPB elects to exercise the option after that date, further amounts would become payable to GoldStone. GoldStone currently has cash resources of approximately US$3.0 million. With the cessation of the gold exploration programme and the option agreement in place with BHPB over the bauxite interests, the Directors decided to seek a new project for the Company. The criteria for the new project were that it should be relatively low risk and would provide early cash flow to the Company. The Directors believe that the Swartdoring Diamond Project has the potential to fulfil these criteria thereby rebuilding value for Shareholders. Independent Valuation of the Swartdoring Diamond Project An independent valuation report on the Swartdoring Diamond Project has been undertaken by Snowden Mining Industry Consultants (Pty) Ltd ('Snowden'). In Snowden's opinion, the project value is between US$4 million and US$20 million, with a preferred value of US$12 million. On the basis of the preferred value, a 70 per cent. interest would have a value of US$8.4 million. The full text of Snowden's report is set out in the Circular. The Swartdoring Diamond Project Background The Swartdoring diamond deposit is a preserved diamondiferous palaeochannel of the Swartdoring river in the Northern and Western Cape Provinces of South Africa. The first permissions for the exploration of the area, which consists of a number of farms, were granted in 1997 to GrindStone Mining by the DME. Xanadu Mining, through its subsidiaries, has invested approximately US$500,000 in the development of the Swartdoring Diamond Project since 1997. In order to advance the project, the Directors estimate that an investment of approximately US$500,000 will be required to fund direct exploration expenses. The exploration will be conducted in order to complete a mining feasibility study on the inferred resource of the project. The subsurface channel, which is buried beneath surficial sand cover, ranges from 400 to 2,000 metres in width and occupies an area of 1,345 hectares. This area has been explored by means of outcrop mapping, ground-penetrating radar, 630 reverse circulation drill holes, and by bulk-sample excavations at each end of the reach. An inferred resource of 12 million tonnes of loose, uncemented, diamond-bearing gravel, interpreted from drill hole records, lies beneath loose to slightly cemented sandy overburden at an average stripping ratio of 12.4. There is a possibility to extend this resource to approximately 49 million tonnes of diamond-bearing gravel after analysis of results from further drilling work and bulk sampling operations. Sampling at the eastern end of the preserved palaeochannel has recovered 220 stones weighing a total of 177.73 cts, equivalent to an average size of 0.81 cts /stone. The last parcel of stones was classified as very good gem quality, weighed 16.98 cts, and was valued at US$343/ct in 1998. This equates to approximately US$450 in current day terms. The largest stone in this parcel weighed 3.48 cts. Sampling at the western end of the preserved palaeochannel recovered 131 stones weighing a total of 68.49 cts, equivalent to an average size of 0.525 cts. The largest stone recovered was 11.60 cts. Statistical analysis of the gravel bulk sampling results for samples collected at either end of the palaeochannel indicates an average grade of 3.2 cpht for both ends of the palaeochannel. Summary of Previous Exploration Results Grade (inferred) 3.18 cts per 100 tonnes Stone quality Size range = 0.2 to 11.6 cts Average size = 0.81 cts Value (2005) = US$475 per ct. Tonnage (inferred) 12 million tonnes Equating to in situ 360,000 cts Value in situ: US$181 million Potential In arriving at the in situ value set out above, the potential of the upper gravels and the gravels from the mid-channel section have not been taken into consideration. Although drill records show the existence of upper gravels and the continuation of basal gravels in the mid-channel area, these gravels have not been bulk sampled and tested and were therefore excluded from the inferred resource calculation described above. There are, however, no geological reasons why the grade and tonnage of the mid-section of the palaeochannel would differ substantially from what was found on the eastern and western ends of the channel. Upper Gravels Tonnage (estimated) 20 million tonnes Mid-Channel (not fully explored) 17 million tonnes Exploration Objectives Further exploration in order to complete a feasibility study on the inferred resource of 12 million tonnes of diamond bearing gravel is necessary. This would require the completion of percussion drilling over and bulk sampling of the eastern and western sections of the channel. From drill log interpretation, the channel-reach will be subdivided into separate fluvial environments, each of which will then be bulk sampled. Reverse circulation drilling will be used to delineate the final position of drill sites and a wide diameter drill will be used to extract bulk samples of gravel from those parts of the channel. The bulk sampling would aim to get representative values of grades in various environments and will assist in determining the global and regional gravel tonnage and diamond value. Drill records of the entire channel will also be used to determine the average stripping ratio. A financial feasibility study will be made upon receipt of bulk sampling data. If this part of the project appears feasible, further commercialisation of the project will take place, which may entail the development of a mine thereon or a sale thereof. Should this be successful it may also encourage a later exploration phase of the diamond bearing basal and upper gravels in the mid-channel section. If so, similar percussion drilling and bulk sampling techniques will be applied to the mid-channel section in order to enable a separate feasibility study thereon. The untested upper gravels in the eastern and western-channel areas will be determined from results obtained during the planned exploration. Company Structure and Current Status of Authorisations GrindStone Mining and Multi-Direct Mining were formed for the purpose of exploring the Swartdoring Diamond Project. The companies are wholly-owned subsidiaries of Xanadu Mining. GeoQuest currently owns approximately 70 per cent. of the issued share capital of Xanadu. The first permissions for the exploration of this project were granted in 1997 by the DME and GrindStone Mining and Multi-Direct Mining have held a number of permissions since then. The DME has granted a prospecting right to Multi-Direct Mining over one of the farms situated in the Western Cape and it is expected that the prospecting right will be notarially executed shortly. The applications of GrindStone Mining over certain properties in the Western and Northern Cape Provinces have also been accepted and it is expected that these prospecting rights will be granted soon. Terms of the Acquisition Under the terms of the Acquisition Agreement, GoldStone has conditionally agreed to purchase a 70 per cent. interest in Xanadu Mining from GeoQuest. Additionally, under the terms of the agreement, GeoQuest will assign to GoldStone 70 per cent. of the inter-company debt owed by Xanadu to GeoQuest comprising of the amount as at 28 February 2006 and stated in the financial statements and expenses approved by GoldStone and incurred in the normal course of business. On completion the debt will amount to approximately £760,000. The consideration payable at completion will be the issue and allotment of 50,640,000 Consideration Shares to GeoQuest. At the mid-market price of 1.1 pence per Ordinary Share at the close of business on 2 April 2007, the Consideration Shares have a value of £557,040. The Acquisition is conditional, inter alia, on: • The passing of the Resolution by Shareholders which would grant the Directors authority to issue the Consideration Shares; • The granting and notarial execution of prospecting rights over all the farms comprising the Swartdoring Diamond Project by the DME in favour of GrindStone Mining and Multi-Direct Mining; • The successful listing of GoldStone on the AltX (the Alternative Exchange of the Johannesburg Stock Exchange), further information on which is set out below; • The approval of the Acquisition by the South African Reserve Bank; and • The passing of a special resolution by the members of GeoQuest approving the Acquisition Agreement. Completion of the Acquisition will not take place until satisfaction of all of the conditions, which must occur before 30 October 2007. The Acquisition Agreement contains certain warranties given by GeoQuest to GoldStone. On completion of the Acquisition, GeoQuest will hold 90,640,000 Ordinary Shares, representing 49.95 per cent. of the enlarged share capital. The Directors understand that the directors of GeoQuest intend that, at the time of the listing of GoldStone on AltX and completion of the Acquisition, GeoQuest will be liquidated and the directors of GeoQuest will declare a dividend in specie comprising the distribution of the Ordinary Shares held by GeoQuest to its shareholders. Following this distribution, the shareholders in GeoQuest will hold 90,640,000 Ordinary Shares, representing 49.95 per cent. of the enlarged share capital. The approximate anticipated interests of the Directors in the Company, all of which arise as a result of the dividend expected to be paid by GeoQuest, are as follows: Director No. of Percentage Ordinary Shares Sir Michael Oliver 1,599,915 0.9 Nico van der Hoven 16,271,417 9.0 Dr. Lawrie Minter 7,705,241 4.2 Jurie Wessels 3,576,291 2.0 29,152,864 16.1 Listing on AltX and SARB approval As set out above, the Acquisition is conditional, inter alia, on a listing of GoldStone on the AltX. The Directors are of the opinion that a listing on the AltX would open new avenues for fund raising for the Company and will provide improved liquidity for the Company's shareholders at a relatively low cost. In addition, an AltX listing will allow the Company to invest in the South African Democratic Community, a region that is well known for its exploration opportunities. South Africa, in common with many other countries, operates a policy of exchange control, which is administered by the South African Reserve Bank (the 'SARB'). During November 1999 and June 2003, the SARB approved the injection of funds originating from GeoQuest in South Africa into GoldStone in order to fund GoldStone's exploration activities. During June 2003 the SARB also approved the expatriation by GeoQuest from South Africa of sufficient funds in order to finance the flotation of GoldStone on AIM. On 31 August 2006 GeoQuest applied for permission from the SARB to sell the Swartdoring Diamond Project to GoldStone. This application was refused because in terms of current exchange control policy, the acquisition of the Swartdoring Diamond Project would amount to a 'loop structure', namely an acquisition of property inside the SADC by a foreign (non-South African) entity originally financed by a South African company. Under this SARB policy, GoldStone is precluded from investing or acquiring any assets within the borders of the SADC. Further submissions and proposals were made by GeoQuest and GoldStone to the SARB in order to allow GoldStone to acquire assets in the SADC and it was resolved during March 2007 that the SARB would favourably consider an application by GoldStone to invest in the SADC if GoldStone is listed on the AltX.
