Vaaldiam Resources Ltd.: Positive Diamond Results from Initial Brauna Bulk Sample

TORONTO, ONTARIO--(CCNMatthews - Dec. 12, 2006) - Vaaldiam Resources Ltd. (TSX:VAA) (60% interest) and partner Majescor Resources Inc. (TSX VENTURE:MAJ) (40% interest) are pleased to report that 38 diamonds with a total weight of 4.78 carats have been recovered from 21.5 dry tonnes of kimberlite processed thus far from the 1.7 hectare Brauna 3 pipe, located in the State of Bahia, Brazil. The five largest stones recovered to date weigh 0.49, 0.46, 0.43, 0.41 and 0.31 carats.

The following table summarizes the diamond results from the processing of the mini-bulk sample collected from the first of three vertical shafts excavated into the Brauna 3 pipe to depths ranging from 6 to 16 metres.

Note 1: All diamonds recovered are larger than 0.85 mm using a
square mesh screen.
Note 2: The shaft interval from 0 to 4 metres was comprised of soil,
calcrete and calcretized kimberlite and was not sampled.


Vaaldiam's dense media plant, which is situated just 5 kilometres from the Brauna property, is being utilized by the joint venture to process the 50 tonne mini-bulk samples extracted from two of the four Brauna pipes. The diamond recovery plant consists of a crushing and feed circuit, a 300 kilogram per hour dense media separation module, and a secure diamond recovery circuit. Simulated diamond "tracers" with a density similar to diamond, are being utilized to measure the efficiency of the plant, and indicate an average recovery rate of 98.7% based on the samples processed to date. Reprocessing of the plant tailings will be completed as part of an audit of the processing plant efficiency, to ensure the highest recovery rate is achieved for the sample processing. A description of the diamonds will be provided upon the completion of the sampling program.

The Brauna 3 pipe was discovered by De Beers in 1992 during follow-up exploration of a high interest heavy mineral anomaly. De Beers extracted approximately 7.5 tonnes of material from the surface of the pipe, which produced 7 diamonds with a total weight of 0.18 carats, suggesting a diamond grade of only 2.38 cpht for the pipe. The average size of the diamonds recovered by De Beers was 0.03 carats per stone, and the largest stone recovered weighed 0.10 carats. The current mini-bulk sampling program being completed by Vaaldiam and Majescor is focusing on testing the kimberlite below a depth of 4 metres, where the kimberlite is less diluted by the calcrete, which forms a hard layer covering the surface of the Brauna pipes. Ken Johnson, President and Chief Executive Officer of Vaaldiam commented that "the diamond grade appears to become more consistent with depth as the kimberlite becomes less diluted by calcrete. We are extremely pleased with the diamond results, as they show a fourfold improvement over the 1992 surface sampling results in the average size of the diamonds, and an almost tenfold improvement in the diamond grade."

Approximately 25 tonnes of kimberlite remains to be processed from the Brauna 3 pipe, and is expected to be completed by year end. An additional 50 tonnes of kimberlite from the 1.0 hectare Brauna 7 pipe will be processed during January and February 2007.
About Vaaldiam

Vaaldiam is a Canadian-based diamond exploration company primarily involved in the exploration and development of advanced-staged diamond properties in Brazil. Vaaldiam is also focused on the development of its Duas Barras alluvial diamond mine in the State of Minas Gerais, Brazil, where an indicated gravel resource of 1.7 million cubic metres and an inferred resource of approximately 1.0 million cubic metres, containing a combined 430,000 carats has been delineated by bulk sampling and drilling. Mine construction is underway, with production scheduled to commence in Q1-2007. On its Pimenta Bueno diamond property in the State of Rondonia, Brazil, joint venture partner Rio Tinto has committed to the second year of exploration work and is completing a drill program which has recently resulted in the discovery of additional kimberlite pipes. Delineation and sampling of the new discoveries is underway, and is focused on defining targets for bulk sampling early next year. Vaaldiam has 81.4 million common shares outstanding and approximately C$13.0 million in cash available for the exploration and development of its diamond properties.
