Brazilian Diamonds Limited bulk testing continues at Salvador 1 Patos Laboratory accredited to ISO 17025

Brazilian Diamonds Ltd announces that bulk sampling on the Company’s 100% owned Salvador 1 diamond bearing kimberlite in central Bahia State, Brazil has recommenced and the important ISO 17025 accreditation for kimberlite indicator mineral recovery from heavy mineral concentrates at the Company’s laboratory in Patos de Minas, Minas Gerais has been reconfirmed following an extensive Brazilian government departmental audit.

Salvador 1 testing programme

The excavation and testing programme at Salvador 1 continues the Company’s evaluation of the Salvador 1 kimberlite following the encouraging recovery of diamonds during a smaller, mini-bulk sampling programme carried out early in 2007. The programme comprises pitting and testing at six locations spaced across the Salvador 1 kimberlite, which is approximately six hectares in surface area, with each pit designed to recover approximately 1,300 tonnes of kimberlite. Excavation of the first pit (Pit 1) was completed late last year and excavation of the second and third pits commenced prior to the Christmas break. Diamond-bearing sand and gravel overlie each of these pits.

At least six different kimberlitic rock types or “phases” have been identified from the field examination of exposures in Pit 1. Each of these phases is interpreted to represent a different intrusive event and thus potentially may carry a different diamond sample. The identification of multiple phases emphasizes the importance of testing the entirety of the six different pits to determine a representative diamond concentration for the body. The different phases also have variable processing characteristics, requiring some ongoing adjustments to the primary disaggregation plant on site.

The Company has also now completed the third of a three hole diamond drill programme to test the body at depth. As with the previous two holes, encouragingly the third hole was completed to its targeted depth of 200m and ended in kimberlite.

Patos de Minas Laboratory

The Company’s diamond laboratory accreditation to ISO 17025 has been confirmed following the completion of a comprehensive audit by INMETRO (the National Institute of Metrology, Normatization and Industrial Quality) in Brazil. The Patos de Minas Laboratory is Brazil’s only Indicator Mineral Laboratory accredited to ISO 17025 and represents an important element of the Company’s technical competence providing a significant advantage in achieving a fast and reliable turnaround of sample results from the Company’s field and bulk sampling programmes.
