Abu Dabbab - Tantalum-Tin-Feldspar (50% Gippsland)

Introduction

The Abu Dabbab tantalum-tin-feldspar deposit is located within the Central Eastern Desert in Egypt. The deposit is located on land about 16km westwards from the western shore of the Red Sea.

The deposit is covered by two Exploitation Leases (1658 & 1659) granted in the name of Tantalum Egypt LLC, a company incorporated in Egypt and owned 50% EGSMA and 50% by Tantalum International Pty Ltd which is a 100% owned subsidiary of Gippsland Ltd. The proposed plant site located 6km from the Red Sea coast has been secured under Ministerial Decree No. 11/2003 and provides for an area of 14km 2.

Previous exploration

Tin-tungsten mineralisation at Abu Dabbab has been known since the 1940s but it was not explored until the early 1970s when a joint Soviet-Egyptian team, completed an extensive exploration programme. In the early 1990s the project was further explored by a joint venture between the Egyptian Government (EGSMA) and Geominera Italiana. The previous work included 28 diamond drill holes, three adits, one crosscut, numerous trenches, surface sampling, bulk sampling and metallurgical tests.

ippsland carried out some re-sampling of the adits to verify the previous results, collected bulk samples totalling 43 tonnes which was used to conducted additional detailed metallurgical testwork in Australia. Encouraged by the results of the testwork, Gippsland commence a Bankable Feasibility Study which was completed in September 2004 by the international engineering Group Lycopodium Pty Ltd.

Bankable Feasibility Study

Bankable Feasibility Study – 2Mtpa

The BFS completed during October 2004 by the international engineering group Lycopodium Ltd determined that the world-scale 40Mt Abu Dabbab deposit has the potential to become a major global supplier of tantalum whilst operating from a low cost basis. Based upon the scheduled mill feed-rate of 2 million tonnes per annum the sUmarised results of the BFS are:

  • Gross sales revenue in excess of US$500 million over initial 13 years of its estimated mine life (based upon tantalum and tin sales alone)
  • Net free cash flow of US$127 million over initial 13 years of estimated 20-year mine life
  • IRR 17.4% on all equity basis
  • IRR 29% on basis 80% debt & 20% equity
  • Capital Expenditure US$80.5 million
  • Capital repayment period 4.5 years
The BFS determined that the project will produce in excess of 650,000 pounds of tantalum pentoxide ("Ta2O5") per year which will firmly establish the operation as the world's second largest tantalum producer. The project will also produce 1,530 tonnes of tin metal per year.

The BFS also determined that the project will generate gross sales revenue in excess of US$500 million during the first 13 years of its estimated 20-year mine life. These sales are from tantalum and tin only and exclude all potential feldspar sales revenues

The BFS also determined that the project will generate a net free cash flow of US$127.6 million during the first 13 years of its estimated 20-year mine life.

The BFS also concluded that the project has an Internal Rate of Return ("IRR") of 17.4% on an all equity basis. Assuming a debt:equity ratio of 4:1 the IRR for equity holders increases to approximately 29%.

The BFS completed during October 2004 by the international engineering Group Lycopodium Ltd determined that Abu Dabbab will produce in excess of 650,000 pounds of Ta 2O5 (tantalum pentoxide) per year which will firmly establish it as the world's second largest tantalum producer.

Gippsland has entered into two 4-year Heads of Agreement for the off-take of 420,000 pounds of tantalum per annum. Additional off-take agreements are currently being negotiated.

Based upon a mill feed-rate of 2Mtpa, the Abu Dabbab project is also scheduled to produce 1,540 tonnes of tin per annum which will be sold direct to industry and/or via the London Metal Exchange.

The Abu Dabbab project has the potential to produce approximately 1.5 million tonnes per annum of ceramic grade feldspar which would be used in the European ceramic industry. In-plant testwork undertaken in Italy demonstrated that the Abu Dabbab feldspar is ideal for the production of ceramic tiles and sanitary wares, the major use of the material. Consideration of this additional phase of the Abu Dabbab project will be undertaken following commissioning of the tantalum/tin operation.

Gippsland has entered into Heads of Agreement with a major Italian ceramics group for the off-take of 2.65 million tonnes of feldspar delivered over a 4-year period.
