Dwyka Diamonds Limited13 March 2006 Dwyka Diamonds Limited India update • Sample site 100km north-west of recent Rio Tinto Kimberlite field discovery • Sample analysis strongly suggests source rock is diamondiferous Dwyka Diamonds Limited ("Dwyka" or "the Company"), the AIM and ASX listeddiamond developer and producer today announces positive results from its recentstream sediment sampling programmes in Uttar Pradesh, India. Analysis of two samples from the Uttar Pradesh programme suggest the indicatorminerals were derived from a diamondiferous source rock. In material derived from one of the samples, chrome spinel and pyrope garnetsexhibit compositions typical of the diamond inclusion field. The sample site islocated approximately 100km north-west of the Bunder Kimberlite field discoveryrecently announced by Rio Tinto. Analysis of the recent samples strongly suggests the source rock isdiamondiferous. The importance of this discovery is underpinned by the fact thatRio Tinto has recently located diamondiferous bodies intruding the same basementrocks. Additionally the surface textures of the indicator minerals found byDwyka, and the distances from the Rio Tinto discoveries, would suggest that bothsamples contain indicator minerals sourced from as yet undiscovered kimberlitebodies. Commenting today Melissa Sturgess, Executive Chairman, said, "Our priority nowis to conduct follow up sampling and additional field work in order to locatethe source of the kimberlitic indicator minerals. We shall be concentratingefforts on identifying the presence of kimberlites while working closely withour JV partners in India."
