Vaaldiam Resources Ltd.: Duas Barras Diamond Project Moves Towards Production

TORONTO, ONTARIO--(CCNMatthews - May 29, 2006) - Vaaldiam Resources Ltd. (TSX:VAA)

- Engineering contract awarded for design and construction of diamond production plant at Duas Barras;

- Construction of mine infrastructure underway;

- Delineation drilling program nearing completion;

- 43-101 compliant resource estimate scheduled for end July;

- 48 diamonds totaling 16.27 carats recovered from 149 m3 gravel sample from Pit # 2;

- Testing of gold content in gravels on-going with results expected in August; and

- Vaaldiam increases its interest in the Duas Barras project to 75%.

Vaaldiam Resources Ltd. (TSX:VAA) (75% interest) has granted the engineering contract for the design of the production scale diamond recovery plant at Duas Barras to Multigeo-Mineracao, Geologia e Meio Ambiente Ltda. of Sao Paulo, Brazil. Multigeo is one of Brazil's leading engineering firms with significant experience in the design and construction of alluvial mining operations.

Ken Johnson, President and CEO of Vaaldiam, in commenting on Multigeo, said that "we are extremely pleased to add Multigeo to our mine development team at Duas Barras. Multigeo's engineering and geological team has a significant amount of experience in the design and construction of diamond recovery plants and the development of mine and reclamation plans related to alluvial mining operations. Multigeo was responsible for the design and construction of the Camargo Correa alluvial diamond and gold mine in the Nortelandia diamond district, Mato Grosso state, Brazil, and remains a technical advisor to the mine. Multigeo's hands-on experience in the development, construction and operation of an alluvial diamond mine in Brazil should contribute to the rapid and successful development of our Duas Barras Mine."

Initial plant design and mine planning is currently underway, and fabrication and construction of the processing plant is expected to commence during Q3-2006, with production scheduled to commence during Q4-2006. Improvements to the infrastructure of the Duas Barras project are in progress, with the construction of additional accommodation for mine and construction staff, a new administrative building, and expanded garage facilities. Hydrological testing is also underway to measure groundwater flow in the proposed mining areas, and environmental baseline studies are being completed in accordance with the environmental impact study authorized by the regulatory authorities in Brazil.

Delineation drilling is nearing completion, with 154 holes totaling 3,110 metres having been drilled on a 50 by 50 metre grid pattern. The drilling so far has identified two main deposits of the white basal gravel, which has been the target of Vaaldiam's on-going bulk sampling program. The North Zone, which appears to be the more extensive of the two channels of alluvial gravel, has been traced over a distance of 1,100 metres, reaching widths of 250 metres. Detailed drilling indicates that the North Zone has an average thickness of 7 metres for the white basal gravel unit, which is covered by up to 14 metres of sand and soil.

The South Zone has been traced by drilling over a distance of 300 metres, exhibiting a channel width of 250 metres. The basal gravels comprising the South Zone have an average thickness of 3 metres, and are covered by approximately 8 metres of sand and soil. Only 30% of the property has been tested by drilling thus far, and with both the North and South zones remaining open along their strike, additional gravel resources will likely be added as a result of future planned drilling programs. A resource estimation compliant with National Instrument 43-101 is expected to be completed by the end of July.

Vaaldiam's bulk sampling program is also continuing, with processing of gravels from Pit # 2 currently underway. Pit # 2 is situated at the western end of the North Zone approximately 400 metres to the west of Pit # 1, which produced 129 diamonds totaling 30.67 carats from 132.6 m3 (approximately 239 tonnes) of gravel for a recovered grade of 0.23 ct/m3 or 12.85 cpht. The individual diamonds recovered from Pit #1 ranged in size from 0.10 carats to 1.24 carats, with an average stone size of 0.24 carats (previously reported on December 7, 2005). Processing of the upper 1 metre of the basal gravel sequence from Pit# 2 has resulted in the recovery of 48 diamonds totaling 16.27 carats from 149.2 m3 (approximately 269 tonnes) of gravel for a recovered grade of 0.11 ct/m3 or 6.05 cpht. The individual diamonds recovered range in size from 0.09 carats up to 2.39 carats in weight, and have an average size of 0.34 carats per stone. The completion of the bulk sampling program at Pit# 2 is expected by mid-June.

Testwork is also underway to determine the gold content of the diamond-bearing gravels at Duas Barras. Heavy mineral concentrates resulting from the processing of the fine less than 2 mm size fraction screened and directed through the gold circuit in the Company's bulk sampling plant is currently being analyzed to determine the gold content of each of the bulk samples. A previous mining operation by Vaaldiam's joint venture partner, Mineracao Marly Ltda. in 2002 reported recovering 24.5 ounces of gold (approximately 762 grams) from 4,263 m3 of gravel extracted from the basal sequence, for a calculated recovered gold grade of 0.18 grams/m3. At a gold price of US$650 per ounce, the reported gold content would represent an in-situ value of US$3.75 per cubic metre (approximately US$2.08 per tonne). The current test-work is focused on confirming this reported gold grade, which if positive, would likely offset a significant portion of the operating costs of the planned mining operation at Duas Barras.

On the corporate front, Vaaldiam recently negotiated the purchase of an additional 5% equity interest in the Duas Barras project, increasing the Company's interest to 75%. The interest was acquired through the payment of an advanced royalty of US$50,000 to Mineracao Marly Ltda.
