Vaaldiam Resources Ltd.: Diamond Grade Increases From Brauna 11 Sampling

TORONTO, ONTARIO--(Marketwire - Oct. 18, 2007) - Vaaldiam Resources Ltd. (TSX:VAA) continues to produce significant diamond results from its sampling of the Brauna 11 dike situated on the Company's 100% owned Brauna property in the State of Bahia, Brazil. A second mini-bulk sample has returned 21 diamonds with a total weight of 2.50 carats from 12.16 dry tonnes of kimberlite (13.33 wet tonnes), indicating a recovered grade of 20.56 carats per hundred tonnes (cpht).

This second mini-bulk sample was excavated 200 metres to the northwest of Vaaldiam's initial sample site (reported on October 3, 2007) which produced 19 diamonds with a total weight of 2.81 carats from 16.02 dry tonnes of kimberlite (17.67 wet tonnes), indicating a recovered grade of 17.54 carats per hundred tonnes (cpht). The average stone size of the diamonds recovered from this second mini-bulk sample was 0.12 carats. The five largest stones recovered in the mini-bulk sample weigh 0.87, 0.35, 0.33, 0.17 and 0.13 carats. The diamonds are predominantly white to yellowish-white in colour, with one brown stone (0.35 carats). Roughly half of the diamonds show well-formed crystal shapes, while the balance appear to be fragments due to breakage during processing, or are natural irregular stones. Photos of the diamonds recovered from the mini-bulk sample of Brauna 11 are available for viewing on the Company's website at

The Brauna 11 kimberlite occurrence is a 1.5 to 2.5 metre wide, vertically oriented kimberlite dike situated approximately 2 kilometres south of the diamond bearing Brauna 3 and Brauna 7 pipes. To date, the dike has been traced on surface over a distance of approximately 750 metres and it appears to form part of a northwest-trending dike system that has been traced on surface over a distance of approximately 15 kilometres. Vaaldiam's first sample was extracted from a 6 metre deep shaft that allowed the excavation of fresh kimberlite which does not appear to be diluted by soil and calcrete overlying the dike system. The second most recent sample was excavated from an 8 metre deep shaft located 200 metres to the northwest of the initial sample site.

Ken Johnson, President and Chief Executive Officer of Vaaldiam commented that "these latest results from the Brauna 11 dike confirm the lateral continuity of the diamond mineralization within the Brauna 11 dike system. We now plan to delineate the dike system by core drilling, in an effort to expand the resource potential of the Brauna property, and determine the relationship between this diamond bearing dike and the diamond bearing Brauna 3 and Brauna 7 kimberlite pipes situated immediately to the north, which were the focus of our bulk sampling efforts earlier this year."

The mini-bulk sample collected from the Brauna 11 kimberlite was processed at Vaaldiam's dense media plant situated in Vaaldiam's secure facilities in the town of Nordestina, just 5 kilometres from the Brauna property. The processing plant consists of a crushing and feed circuit, a 300 kilogram per hour dense media separation module and a secure diamond recovery circuit capable of recovering diamonds larger than 0.85 mm using a square mesh screen. Simulated diamond tracers with a density similar to diamond were used to measure the efficiency of the plant. Vaaldiam's geologists and technicians implemented strict chain-of-custody procedures during the extraction and processing of the sample to ensure the security of the sample. Reprocessing of the plant tailings was completed as part of an audit of the processing plant efficiency to ensure the highest recovery rate is achieved for the sample processing.
