Final Results

Aminex PLC 20 March 2007 20 March 2007 AMINEX PLC ("Aminex" or "the Company") Preliminary results for the year ended 31 December 2006 Aminex, the oil and gas company listed on the London and Irish Stock Exchanges, today announces its preliminary results for the year ended 31 December 2006. Highlights • Net loss reduced to US$2.86 million (2005: loss US$4.98 million) • US production ahead of previous year • Active drilling programme due to commence shortly in Tanzania, Egypt and USA • Up to date engineering evaluation shows major increase in 2P value of US properties • Two farm-out agreements concluded on Nyuni licence, Tanzania • Slow but steady progress in North Korea • Seismic completed at Nyuni and further seismic planned for Ruvuma licence this year • First year programme completed in Madagascar and new seismic planned for 2007 Brian Hall, Chief Executive of Aminex, said: "During the year, we consolidated our exploration programme in Tanzania and Madagascar and made good progress in our other areas of operation. We are now poised to launch the most active drilling programme in Aminex's history. We have managed the programme in such a way that shareholders stand to benefit from exploration upside, without being unduly exposed to the outcome of any single well."

Drilling is planned during the current year at the following locations: • Nyuni (Tanzania) • West esh el Mellahah (Egypt); • Alta Loma and South Weslaco (Texas). Depending on progress, drilling may also commence in the Ruvuma Basin (Tanzania) towards the end of 2007, although this now seems more likely to start in 2008. Progress in finalising a Production Sharing Agreement in Kenya has been slow, but we have recently been assured by the Kenyan Energy Minister that we may expect a satisfactory conclusion shortly. A new reserves report for our US properties shows greatly enhanced value, following development drilling and a period of stronger commodity prices, underpinning our current market capitalisation. Two farm outs have now been successfully concluded on the Tanzanian Nyuni licence while our farm-in partner in the Ruvuma area, Hardman Resources Ltd. (" Hardman"), has been acquired by Tullow Oil PLC. The takeover of Hardman slowed down the work programme over Ruvuma in late 2006, but its conclusion leaves us in a 50-50 partnership with Tullow, one of the largest and most successful independent oil companies operating on the African continent today. FINANCIAL REVIEW Aminex's revenue during the current year comprises sales of oil and gas in the USA and sales of goods and services by its oilfield services and supply company. Total revenue of US$5.0 million is 67% higher than 2005 revenue of US$3.0 million, mainly as a result of increased gas sales in the USA and sales of oilfield equipment from the UK. Oil and gas revenue comprises approximately 50% of total revenue in 2006 compared with 61% in 2005. Oil production at 30,000 barrels is 10% up on 2005 whereas gas production has more than doubled from 59mmcf in 2005 to 129mmcf in the current year. The average oil price achieved during 2006 was US$58.35 per barrel, an increase of US$8 per barrel over the 2005 average. Most of the oil sold was from the Group's Somerset field, the production from which is classified as South Texas Sour that is priced at a discount of up to US$4 per barrel against the standard West Texas Intermediate (WTI) pricing. The average gas price obtained in 2006 was US$5.91 per mcf compared with an average price of US$7.81 in 2005. The increase in gas production in the current year is due to two new wells which came on stream at the South Weslaco field during the last two weeks of 2005. Cost of sales at US$3.4 million is US$1.4 million higher than the previous year with much of the increase relating to the cost of oilfield services sales. Nevertheless, average margins of gross profit on oilfield equipment sales during 2006 amounted to approximately 20% (2005: 17%). The depletion and decommissioning charge of US$0.39 million is US$0.55 million lower than the 2005 charge. Included in the 2005 charge was the cost of decommissioning the Sabine Lake field in the USA, whereas no fields have been decommissioned during 2006. After taking these charges into account, the resulting gross profit for the Group in 2006 amounted to US$1.23 million, an increase of US$1.21 million over the 2005 gross profit. As a consequence of continuing cost reductions, mainly in the USA, Group administrative expenses at US$3.97 million are approximately 20% lower than the 2005 charge, which included US$583,000 relating to the settlement and associated legal costs of litigation. The operating loss for the year was US$2.79 million, a decrease of US$2.14 million from the 2005 operating loss of US$4.93 million. After charging net financing costs of US$75,000 (2005: US$49,000), the net loss for the twelve months ended 31 December 2006 has been sharply reduced to US$2.86 million (2005: loss US$4.98 million). Balance sheet exploration and evaluation expenditures during the current period amount to US$1.42 million and comprise mainly seismic work carried out on the Nyuni and Ruvuma licences in Tanzania as well as a gravity survey over the Manja Block 3108 acreage in Madagascar. Expenditures of US$1.1 million (which is stated net of a depletion charge of US$0.39 million) on property, plant and equipment relate to the Group's producing assets in the USA. Included in this expenditure is the Group's participation in drilling a third well at the South Weslaco gas field (two wells were drilled during 2005) as well as further field rehabilitation work at the Shoats Creek field. The cash flow statement shows net cash inflows from financing activities amounting to US$5.44 million, primarily from an equity fundraising in June 2006. During the year, US$52,000 was raised and US$42,000 was repaid on vehicle equipment loans in the USA. At 31 December 2006, the Group's cash balance amounted to US$3.65 million, offset by a minor amount of vehicle equipment debt of US$145,000. OPERATIONS REVIEW Tanzania - Nyuni We anticipate signing a contract imminently for use of the Caroil-6 rig to drill at Nyuni this year. This rig has recently drilled Maurel & Prom's gas discovery well at the nearby Mkuranga licence in Tanzania and will drill a development well in the Songo Songo gas field before delivery to Aminex and partners, anticipated for May. Aminex plans two wells at Nyuni, the first of which will be directionally drilled from the small Kilwani island, which lies one kilometre to the SW of Songo Songo Island. The drilling objective is a prospect known as Songo Songo South. The second well location has yet to be finalised. During the last three months Aminex has conducted an extremely complex " transition zone" seismic programme over the numerous reefs and islands which overlie the licence's leads and prospects. In 2005 a relatively simple marine seismic survey was carried out in navigable waters and the seismic lines in the transition zones, now tied in to the marine lines, provide a far more comprehensive result than has previously been achieved. The Company's partners are Bounty Oil (6%), East Africa Exploration (10%) and Key Petroleum (20%). Discussions continue with Pan African Tanzania (a subsidiary of Orca Exploration, formerly known as East Coast Energy) to participate in this licence. Tanzania - Ruvuma Further onshore seismic is planned for Spring 2007 and preparations are well under way, the results of which will determine drilling locations. Our initial assessment of Ruvuma concludes that this licence area contains several sizeable oil and gas prospects. In the Mozambique part of the Ruvuma Basin the licensing round completed last year has brought in a number of well-known oil companies, including ENI, Anadarko, Norsk-Hydro, Petrobras and others, which have made material financial commitments to exploration of the basin. Exploration acreage on the Tanzanian side of the basin is exclusively in our hands. Partners are Aminex (50%) and Tullow (50%). Madagascar Aminex and its 50-50 partner Mocoh Ltd., operating through a joint company known as Amicoh Resources Ltd., completed a gravity survey over the 10,750 square kilometre onshore Manja concession, Block 3108, earlier in the year and have subsequently reprocessed approximately 2,000 line kilometres of 2D seismic acquired by previous licensees Chevron and Amoco some years ago. The first year work programme has been completed on schedule and a new 500 kilometre 2D seismic survey is scheduled to commence in the third quarter. Since we applied for Manja in early 2005, onshore Madagascar has become a focus of industry interest and Aminex is therefore pleased to have acquired an excellent licence on favourable terms prior to a surge of exploration activity. U.S.A. Aminex USA, Inc., a wholly-owned subsidiary, has interests in four principal producing locations, being Alta Loma, Shoats Creek, South Weslaco and Somerset. A recent reserves report concluded by Oilfield Production Consultants Ltd. attributes a 2P (proved and probable) valuation to all Aminex's properties in the USA of US$84.5 million. Alta Loma produces from a single gas well which was intermittently shut-in for some time as a result of the major fire and explosion at BP's Texas City Refinery, the sole customer for its production. However production has now resumed at Alta Loma and the drilling of a second well is provisionally planned for 2007. Aminex and its partners drilled a third well at South Weslaco during the year, in addition to two gas wells drilled in 2005 which are now on production. The third well was designed to test a deeper Lower Frio sand. So far it has not been possible to flow gas from the deeper formation despite repeated efforts and the well may now be plugged off at the deeper zone and completed for production higher up the formation. Initial well workovers have been carried out at Shoats Creek, Louisiana, and facilities reconstructed and upgraded. The Shoats Creek field has long been considered very promising but the surface terrain is difficult and the underlying geology highly complex. The field lends itself to 3D seismic but this would be a very costly undertaking for a relatively small area. Therefore we can be very encouraged that Forest Oil is conducting extensive 3D seismic over a large area including our properties. In consideration for allowing Forest access to our acreage Forest will make the results of its survey available to us. Thus, after several years of work, we shall finally have a clearer picture of this promising field which will enable us to drill with greater confidence. Kenya Aminex and partners Upstream Petroleum Services Ltd. and SomKen concluded a seismic survey and seabed coring exercise over the near shore areas of Kenya offshore blocks L9 and L10 in the first half of 2006 under the terms of an informal Technical Evaluation Agreement. These areas have now been redesignated as blocks L17 and L18. Extended negotiations have been taking place to convert this acreage to full Production Sharing Agreement ("PSA") status. Aminex has now been assured by the Kenyan Energy Minister that a satisfactory conclusion will be reached in the near future. North Korea In North Korea (the Democratic Peoples Republic of Korea or "DPRK"), progress has been slower than anticipated, mainly on account of a series of bureaucratic delays and a very difficult climate for working. Aminex's area of concentration is the East Sea where a data gathering exercise is under way. It is likely that a new and more comprehensive agreement will be signed with the North Korean authorities which facilitate the introduction of new industry partners and the commencement of a major work programme, but the timing has yet to be determined. This will facilitate accelerated operations and Aminex has been assured that the timetable for the 2005 PSA will be extended to enable commitments to be met in an orderly manner. Aminex considers the oil and gas potential of the DPRK to be very high, even though operations require both patience and perseverance. Egypt On 17th September 2006, as announced to shareholders, a licence for Block 2 in the onshore West Esh el Mellahah area ("WEEM") was finalised in Cairo with the Minister of Petroleum at a formal ceremony. This marked the end of lengthy negotiations and the beginning of a first three year work period, in which three wells are planned commencing in summer 2007. Plans for this programme are well advanced. The main prospects in Block 2 are already covered by 3D seismic data which means that it will be possible to move straight into the drilling phase. Aminex has an interest of 10% in WEEM and its share of exploration costs will be carried through to first commercial production by partners. WEEM is in a proven oil and gas area and close to major existing production in neighbouring WEEM Block 1. Aminex is reviewing further exploration opportunities in Egypt. STRATEGY & PROSPECTS Aminex is about to embark on an ambitious drilling programme, in East Africa and the USA. The Company has a well diversified spread of risk and a balanced portfolio ranging from proved reserves in Texas, upcoming drilling close to established production at Nyuni and in Egypt, two major and prospective licences in industry "hot spots" at Ruvuma and in Madagascar and, at the far end of the spectrum, exclusive rights to all the potentially petroleum-bearing basins of North Korea. Recent highly encouraging political developments in North Korea may serve Aminex's interests well, while the Company's early entry into the East Africa region positions it strategically as a pioneer in an exciting new region. 20 March 2007 Group Income Statement for the year ended 31 December 2006 Notes 2006 2005 US$'000 US$'000 Revenue - continuing operations 2 5,019 3,000 Cost of sales (3,401) (2,038) Depletion, depreciation and decommissioning (386) (941) Gross profit 1,232 21 Administrative expenses (3,974) (4,895) Depreciation (45) (56) Loss on operations (2,787) (4,930) Financing income 3 165 123 Financing costs 4 (240) (172) Loss before tax (2,862) (4,979) Income tax expense - - Net loss for the financial year - continuing operations 2 (2,862) (4,979) Basic and diluted loss per Ordinary Share (in US cents) 5 (1.74) (3.85) Group Statement of Recognised Income and Expense for the year ended 31 December 2006 2006 2005 US$'000 US$'000 Currency translation differences 14 (18) Net gain/(loss) recognised directly in equity 14 (18) Loss for the financial year (2,862) (4,979) Total recognised income and expense for the year (2,848) (4,997) Attributable to the equity holders of the Parent Company (2,848) (4,997) Group Balance Sheet at 31 December 2006 2006 2005 US$'000 US$'000 Exploration and evaluation assets 6 17,065 15,649 Property, plant and equipment 9,424 8,368 Other investments 418 418 Total non current assets 26,907 24,435 Trade and other receivables 1,532 1,179 Cash and cash equivalents 3,648 3,884 Total current assets 5,180 5,063 Total assets 32,087 29,498 Liabilities Current liabilities Interest bearing loans and borrowings (43) (42) Trade and other payables (1,116) (1,946) Decommissioning provision (194) (201) Total non current liabilities (1,353) (2,189) Non current liabilities Interest bearing loans and borrowings (102) (93) Decommissioning provision (2,183) (2,127) Total non current liabilities (2,285) (2,220) Total liabilities (3,638) (4,409) Net assets 28,449 25,089 Equity Issued capital 7 11,916 11,057 Share premium 7 44,010 40,102 Capital conversion reserve fund 234 234 Share option reserve 729 187 Share warrant reserve 899 - Foreign currency reserve (61) (75) Retained earnings (29,278) (26,416) Total equity 28,449 25,089 Group Statement of Cashflows for the year ended 31 December 2006 2006 2005 US$'000 US$'000 Operating activities Loss for the financial year (2,862) (4,979) Depletion, depreciation and decommissioning 431 997 Foreign exchange gains/(losses) 20 (9) Financing income (165) (123) Financing costs 240 172 (Gain)/loss on sale of plant and equipment (11) 15 Equity-settled share-based payment charge 542 26 Decrease in trade and other receivables 2 4,923 Decrease in trade and other payables (398) (3,149) Net cash absorbed by operations (2,201) (2,127) Cost of decommissioning (165) (62) Interest paid (12) (15) Tax paid - - Net cash outflows from operating activities (2,378) (2,204) Investing activities Acquisition of property, plant and equipment (1,986) (1,317) Expenditure on exploration and evaluation assets (1,548) (1,429) Acquisition of investment assets - (44) Proceeds from sale of property, plant and equipment 45 37 Interest received 192 90 Net cash outflows from investing activities (3,297) (2,663) Financing activities Proceeds from the issue of share capital 5,708 8,698 Payment of transaction costs (279) (751) Loans repaid (42) (82) Loans received 52 119 Net cash inflows from financing activities 5,439 7,984 Net (decrease)/increase in cash and cash equivalents (236) 3,117 Cash and cash equivalents at 1 January 3,884 767 Cash and cash equivalents at 31 December 3,648 3,884 Notes to the Financial Information for the year ended 31 December 2006 1 Statement of Accounting Polices The financial information has been prepared in accordance with the recognition and measurement principles of all International Financial Reporting Standards (IFRS), including Interpretations issued by the International Accounting Standards Board ("IASB") and its committees and endorsed or expected to be endorsed by the European Commission. The accounting policies used are consistent with those set out in the audited Annual Report for the year ended 31 December 2005, which is available on the Company's website, www.aminex-plc.com. 2 Segmental Information The Group's primary reporting format is geographical segments, being the America, Africa, Asia and Europe. The Group's other operations by geographical segment do not currently represent 10% or more of the Group's revenue or assets and have therefore not been separately disclosed. The Group's secondary reporting format is by business segment, being (a) exploration and evaluation, (b) producing oil and gas properties and (c) the provision of oilfield goods and services. The Group's revenues and profits arise from oil and gas production in the USA and the provision of oilfield equipment and services in Europe. Segment results, assets and liabilities include items directly attributable to each segment as well as items that can be allocated on a reasonable basis. Inter-segment revenue is not material and has therefore not been disclosed separately below. Net assets before borrowings have been adjusted to eliminate the impact of intercompany financing. Segment capital expenditure is the total amount of expenditure incurred during the period to acquire segment assets that are expected to be used for more than one period.

The diluted net loss per Ordinary Share is calculated using a numerator of the net loss for the financial year and a denominator of the weighted average number of Ordinary Shares outstanding and adjusting for the effect of all potentially dilutive shares, including share options, assuming that they had been converted. The calculations for the basic net loss per share for the years ended 31 December 2006 and 2005 are as follows: 2004 2005 Net loss for the financial year (US$'000) (2,862) (4,979) Weighted average number of Ordinary Shares ('000) 164,289 129,434 Basic loss per Ordinary Share (US cents) (1.74) (3.85) There is no difference between the net loss per Ordinary Share and the diluted net loss per Ordinary Share for the years 31 December 2006 and 2005 as all potentially dilutive Ordinary Shares outstanding are anti-dilutive. There were 7,591,000 anti-dilutive share options and 4,886,384 anti-dilutive share warrants in issue as at 31 December 2006. 6 Exploration and evaluation assets Tanzania Other Total US$'000 US$'000 US$'000 Cost and net book value At 1 January 2006 15,258 391 15,649 Additions 821 191 1,012 Employment costs capitalised 249 155 404 At 31 December 2006 16,328 737 17,065 7 Issued capital and share premium Issued Share Capital Premium US$'000 US$'000 At 1 January 2006 11,057 40,102 Exercise of options 83 234 Issue of shares in part settlement of commercial transactions 35 199 Proceeds from placing net of issue costs 741 3,475 At 31 December 2006 11,916 44,010 8 Comparative figures Comparative figures have been restated where necessary to reflect the current period's presentation. 9 2006 Reports and Accounts The 2006 Report and Accounts will be posted to shareholders shortly. 10 Statutory information The financial information set out above does not constitute the Company's statutory accounts for the year ended 31 December 2006 within the meaning of the Companies (Amendment) Act, 1986.
