The new kimberlite occurrence was discovered during prospecting in the Itapicuru river The Itapicuru River is a river in Bahia state of eastern Brazil. The Itapicuru rises in the northern part of the state, and flows east to empty into the Atlantic Ocean. area, situated in the southern part of the Brauna property, a location known as the "Garimpo do Bastiao", the site of substantial alluvial al·lu·vi·al adj.

The new kimberlite dike, named Brauna 17, was exposed in a surface trench located just 50 metres from the Itapicuru River. The dike exhibits a width of 1.0 metre and strikes in an east-west direction Noun 1. east-west direction - in a direction parallel with lines of latitude direction, way - a line leading to a place or point; "he looked the other direction"; "didn't know the way home" , roughly perpendicular to the northwesterly north·west·er·ly adj. 1.

The exploration program on this dike will focus on determining if the dike might be the primary source from which the diamonds recovered from the "Garimpo do Bastiao" eroded. A map showing the location of the new discovery is available on Vaaldiam's website at www.vaaldiam.com/pagefind.php?id=39. The Brauna project comprises three exploration concessions which now encompass four known kimberlite pipes, or blows associated with a system of kimberlite dykes that have been traced over a distance of approximately 15 kilometres. Based only on the surface exposures, the pipes range in area from 0.50 hectares at the Brauna 7 pipe, to 2.0 hectares at the Brauna 3 pipe. Surface exposures of kimberlite within the dyke or fissure fissure /fis·sure/ (fish´er) 1. any cleft or groove, normal or otherwise, especially a deep fold in the cerebral cortex involving its entire thickness. 2. a fault in the enamel surface of a tooth. systems indicate widths ranging from 0.7 metres at the Brauna 6 occurrence, to 5 metres at the Brauna 8 occurrence. Drill Program Underway Core drilling of the Brauna 3 kimberlite pipe started in December 2005 with three holes completed. Vertical drill hole BRA01-01 tested the south lobe lobe (lob) 1. a more or less well-defined portion of an organ or gland. 2. one of the main divisions of a tooth crown. of the Brauna 3 pipe, and was drilled to a depth of 201.45 metres intersecting in·ter·sect v. in·ter·sect·ed, in·ter·sect·ing, in·ter·sects v.tr. 1.

This hole intersected kimberlite at a down-hole depth of 13.65 metres and is currently in kimberlite at a depth of 43.20 metres. The following table summarizes the results of the drilling completed at the Brauna 3 pipe.

The Brauna 3 pipe is reported to have produced diamonds in the past. During 2000, a local farmer started mining activities at the Brauna 3 pipe. Production records from the manual mining operation, which were reviewed by Vaaldiam's geologists, indicate that during 2000 and 2001, a total of 250 diamonds with a total weight of 372.9 carats were reportedly recovered from colluvial gravels and soils excavated immediately downslope n. 1. a downward slope. Noun 1. downslope - a downward slope or bend declivity, declination, declension, fall, decline, descent downhill - the downward slope of a hill from the Brauna 3 kimberlite. The individual diamonds reportedly ranged in size from 0.20 carats to 15.5 carats, with a significant portion of stones falling in the one to three carat CARAT, weights. A carat is a weight equal to three and one-sixth grains, in diamonds, and the like. Jac. L. Dict. See Weight. range, with the average stone size 1.49 carats. A two-metre thick cap of calcrete overlies the Brauna 3 kimberlite, which appears to have prevented mining of the kimberlite pipe itself. However, a small 8 metre deep pit excavated through the calcrete and into the kimberlite reportedly resulted in the recovery of a 3.55 carat diamond from a small sample. Since these reported results were achieved prior to Vaaldiam and Majescor's acquisition of the Brauna project, they cannot be verified. Vaaldiam expects to commence a mini-bulk sampling program during Q2-2006 to determine the diamond content of the pipes and dikes on the Brauna property.
