Cullinan Mine is currently investigating the feasibility of extending its operations to below a depth of 1,100 metres from surface.  Early in 2004 the project was subsequently reinitiated with the purpose of presenting a sound business case to the De Beers Board of Directors.  Some upfront capital may be applied for towards the latter part of 2004 should the current revalidation work prove successful. Projections show that current reserves will be depleted in 2012.  The Centenary Cut will provide a means of replacing these reserves thus extending the life of the Cullinan mine by some 20 to 25 years. On completion, the new facility will have the capacity to produce nine million tons per annum, which is more than double the current four million tons of installed capacity.
	The Centenary Cut will employ a mechanised block cave as its mining method.  Once sinking operations commence, undercutting will begin about four years later. Full production is expected within seven years On completion, the project is expected to be an investment in excess of R6 billion.
