Corporate profile
Firestone Diamonds plc is an international diamond mining and exploration company with operations in Botswana and South Africa, which are the world's largest and fourth largest producers of diamonds, respectively, and the lowest cost producers among major diamond producing countries.
Firestone has extensive interests in Botswana, which produces over 34 million carats per annum, worth over $3.5 billion. Botswana is considered to be one of the top countries in the world to explore for kimberlite - the primary source rock for diamonds.
Firestone is the largest holder of exploration rights around the Orapa Mine, including the BK11 evaluation project, and around the Jwaneng mine. In addition, De Beers has entered into joint ventures with Firestone over some of Firestone's ground holdings in the Orapa and Jwaneng areas.
The company also holds exploration rights over the entire Tsabong kimberlite field in south-west Botswana, which is one of the largest diamondiferous kimberlite fields in the world. Exploration carried out to date has identified 81 kimberlites, of which 17 have been proven to be diamondiferous. Tsabong is noted for the exceptionally large size of many of its kimberlites, in particular the 180 hectare MK1 kimberlite, which is one of the largest known diamondiferous kimberlites.
Firestone is also exploring for kimberlite in the US on the Laurentia craton, which extends into Canada, where it hosts a number of diamondiferous kimberlite deposits.
Firestone's mining operations include the Bonte Koe, Avontuur and Oena Mines, which are located on the west coast of South Africa, in Namaqualand. Namaqualand has been one of the world's largest alluvial diamond producing regions for the past 60 years, with total production to date estimated to be worth more than $3 billion. Firestone has entered into a mining joint venture with De Beers at the Bonte Koe Mine, which provides the company with guaranteed cash flow for processing gravel mined by De Beers in the area surrounding Bonte Koe.
The company also has a growing portfolio of early stage and advanced exploration projects in Namaqualand, of which the Groen River Valley project, which is being explored by De Beers in joint venture with the company, is the most advanced.
Firestone has a highly qualified management team with extensive experience in the exploration, evaluation and development of diamond projects. Firestone is quoted on the Alternative Investment Market (AIM) of the London Stock Exchange and trades under the symbol FDI.L.
Our Strategy and Objectives
Firestone Diamonds plc is a UK-based international diamond mining and exploration company with operations in Botswana and South Africa. Firestone's objective is to become a leading mid-tier diamond producer.
Firestone's strategy is to use cash flow from alluvial mining operations in South Africa to finance exploration projects in established diamond producing areas with the potential for large scale economic diamond deposits. Firestone's key competitive advantage is its highly prospective portfolio of exploration projects in Botswana, which is the world's largest producer of diamonds. The company is the largest holder of exploration rights around the major Orapa and Jwaneng mines, and controls the entire Tsabong kimberlite field, which is one of the largest diamondiferous kimberlite fields in the world.
Botswana
Tsabong Kimberlite Field
The Tsabong kimberlite field is located in south western Botswana, approximately 280 kilometres south west of the Jwaneng Mine, which is the world's most profitable diamond mine, producing over $2 billion revenue and over $1.8 billion operating profit per annum. The Tsabong project extends over an area of approximately 7,400 square kilometres, and covers the entire Tsabong kimberlite field.
Tsabong is one of the largest diamondiferous kimberlite fields in the world, containing 85 known kimberlites, of which 18 have been proven to be diamondiferous. It is noted for the exceptionally large size of many of its kimberlites, in particular the 180 hectare MK1 kimberlite, which is one of the largest known diamondiferous kimberlites. The Tsabong field also contains five kimberlites larger than 50 hectares and 32 kimberlites between 20 and 50 hectares in size. Work at Tsabong has been primarily focused on 14 high interest kimberlites that were selected on the basis of diamond content, kimberlite indicator mineral ("KIM") chemistry and size. A programme of 17,000 metres of core and percussion drilling has been undertaken on these kimberlites to obtain material for detailed microdiamond, KIM chemistry and petrographic analyses. Bulk samples from selected kimberlites is being undertaken by large diameter drilling to provide an indication of grade and diamond value.
Exploration at Tsabong is targeting approximately 80 well defined geophysical anomalies that have been identified by interpretation of aeromagnetic survey data over the area. The company expects the total number of kimberlites in the Tsabong area to reach more than 100, once exploration has been completed.
With rough diamond prices estimated to have tripled since the Tsabong field was discovered in the early 1980's, the threshold for economic viability is modest. A kimberlite in Tsabong with a grade of 20 cpht and average quality diamonds of $100 per carat would support a large-scale, profitable mining operation. Access to the area is via tarred road from Gaborone and infrastructure in the area is good. Firestone owns a 100% interest in the Tsabong project.
BK11 Kimberlite
The BK11 kimberlite is located in the Orapa kimberlite field in northern Botswana. With eight economic kimberlites out of the 75 kimberlites discovered in the field to date and a new mine being developed by African Diamonds plc in joint venture with De Beers, the Orapa field has an economic ratio of more than 10%, which is significantly higher than the global average of 1%. The Orapa Mine produces approximately $1 billion in revenue and $800 million in operating profit per annum, and is one of the richest diamond mines in the world.
BK11 is located approximately 7 kilometres north-west and 20 kilometres south-east of De Beers' Letlhakane and Orapa mines, respectively, and is within 5 kilometres of the proposed new mine at AK6. The surface area of BK11 is estimated to be 8 hectares, and overburden is shallow at less than 20 metres.
Phase 1 evaluation was completed in June 2008, with very encouraging results. A sample of 135 tonnes of kimberlite produced a sample grade of 10 cpht and a modelled grade of 15 cpht. The quality of diamonds recovered was very good, comprising mostly clear white gemstones, and the value was estimated at approximately $200 per carat in June 2008. BK11 contains approximately 17 million tonnes of kimberlite material to a depth of 120 metres.
Phase 2 evaluation, comprising approximately 2,300 metres of percussion, core and 36 inch large diameter drilling, commenced in July 2008. The Company expects that this will provide sufficient data to define an inferred resource.
With the well developed infrastructure in the Orapa area and a new mine being developed 5 kilometres away at AK6, the grade required for BK11 to be economically viable is modest. Subject to the results of the Phase 2 evaluation work, the Company is examining the feasibility of accelerating a development decision on BK11 to allow first production from BK11 to commence in 2010. Firestone owns an 80% interest in BK11.
