THE BRAZILIAN REALITY OF THE DIAMOND SMALL-SCALE MINING JOSÉ RICARDO THIBES PISANI
How big is the global diamond industry? • Total Production: 160 milion carats per year • Value of production: + $ 13 bilion per year • Global Diamond Exploration Expenditures in 2006 US$ 1 billion. • DIAMOND INDUSTRY IS RELATIVELLY SMALL INDUSTRY, BUT.... • IT IS ONE OF THE MOST PROFITABLE MINING SECTOR • The Major Minind Players in 2006/2007 • De Beers 51M carats valued at $6B • Rio Tinto 35M carats valued at $1.3B • Alrosa 31M carts valued at $2.3B • BHP Bilinton 2.5M carats valued at $440M • Gem Diamonds 0.9M carats valued at $355M Source: RBC Capital Markets
Diamond Exploration Expenditures (US$ Millions) In 1991, the first economic kimberlite pipe in Canada was discovered at Pointe Lake > US$ 2 billion was invested in diamond exploration since 1991 and this results in at least 4 new diamond mines = more than US$ 2 billion of diamond/ year.

Use the excellent work done by De Beers, Rio Tinto, CPRM, etc. > 1.000 kimberlitesdiscoveredsince 1966 (RedondãoKimberlite);
Why the “Majors” walked away from Brazil The “majors” diamond companies did a very good and successful exploration work in Brazil; however they were looking only for WORLD CLASS MINES. Note: Just for reference most of the kimberlites which comprise Point Lake (Ekati Mine) area are smaller than 3 hectares in size. Ekati produces US$ 500 million/ year for at least 25 years. Many small bodies can make a big mine.
Diamond Mining Companies Just for comparason: more than 100 diamond companies are listed and exploring in Canada........

Chapada MineMatoGrosso State • Located in the Mato Grasso State of Brazil, 80 km north east of the state capital of Cuiaba • Largest diamond mine operating in South America • Ni 43-101 compliant resource of 4.8 M bcm at 0.05 cts/bcm • Exploration concessions provide opportunity to expand production and resources • Deposit Characteristics: • The basal conglomerate of the Bauru Formation of varying thickness (up to 20m), which outcrops widely, is considered the most likely local source of diamonds found at Chapada • Operating Performance: • ROM capacity of 60 to 70 bcm per hour • Total sales to date of 32,516 carats @ $411 per carat • 2007 ore processed of 565,776 bcm for total carats of 17,892
The Finance Crisis How the finance crisis will impact the diamond business in Brazil? • The diamond prices are already trading at discounts; • the smaller companies which do not have sustained production and positive cash flow will suffer due to the lack of raising capital opportunities. • A rush to sell projects, claims, equipments already start; • Downsizing is now the strategy for all junior diamond companies in Brazil.
How we can Change this Scenario? Partnership small companies and “garimpeiros” by: 1 – Share the same mining concessions (PLG’s, JV, etc.); 2 – Improving the processing from “garimpeiros” by using the companies technology. 3 – Improvingtheenvironmentalreclamation in order to minimize theimpactoftheareasexploredbygarimperios.
How we can Change this Scenario? Brazilian Diamond Players 1 - Incentives in order to have diamond companies listed at BOVESPA; 2 - Finance and facilities to buy equipments and working capital; 3 -Training in order to have Brazilian diamond valuators with international recognition; 4 - Analysis the possibility to create a Brazilian Diamond Exchange Centre. 5 – Safe regulations and legal stability.
