Vaaldiam’s initial tonnage estimate

Vaaldiam Resources Ltd. announces an initial tonnage estimate of 4.7 million to 5.5 million tonnes for the Brauna 3 kimberlite pipe, situated on the Company’s 100% owned Brauna diamond property, Bahia State, Brazil. The Brauna 3 pipe is one of four diamond-bearing kimberlite pipes discovered to date. The pipes are known to be associated with an extensive diamond-bearing kimberlite dike system which has been traced over a distance of 15 kilometres. This initial tonnage estimate was completed by Wardrop Engineering Inc., an independent geological and engineering consulting firm, and was based on the calculation of the volume of kimberlite defined as a result of a detailed drilling program completed on the Brauna 3 pipe during 2007.

Ken Johnson, President and Chief Executive Officer of Vaaldiam said that we are extremely pleased with the results of the delineation drilling program which has indicated that the Brauna 3 pipe contains sufficient tonnage to potentially support an open pit mining operation. We expect that additional drilling below the 200 metre level of the Brauna 3 pipe, detailed drilling of the other three Brauna kimberlite pipes, and continued drilling of the extensive kimberlite dike systems, will result in a further increase of the volume of kimberlite defined on the Brauna property.

A total of 53 drill holes were completed during the 2007 program directed at the Brauna 3 pipe, on a detailed grid pattern utilizing 25 metre drill spacing, delineating the kimberlite pipe to a depth of approximately 200 metres. The following tables present the estimated kimberlite tonnage to a depth of approximately 200 metres, based on a conservative or rigorous modeling of the body that strictly honors drill hole intersections, and an estimate of the tonnage based on an optimistic model which assumes typical kimberlite morphology or shape. Also included in the tables below is an estimate of the diamond content in carats per hundred tonnes (cpht) based on the results of mini-bulk sampling completed during 2007.
