TORONTO, ONTARIO--(Marketwire - June 15, 2011) - Vaaldiam Mining Inc. ('Vaaldiam' or the 'Company') (News - Market indicators) reports that, for the three months ended March 31, 2011, it has recorded a net loss of $7,641,000 or $0.11 per share compared to a net loss of $2,146,000 or $0.04 per share for the same period in 2010, reflecting the asset impairment of Duas Barras.

Vaaldiam ended the period with a cash position of $5.6 million and working capital of $3.7 million. Vaaldiam also holds 10.6 million shares in Flemish Gold Corp. ('Flemish'), which is focused on gold exploration in sub-Saharan Africa, marketable securities valued at approximately $2.0 million and royalties on two major exploration and development projects. Vaaldiam holds 51% of the Braúna diamond project in Bahia, Brazil as well as two diamond mines, Duas Barras in Minas Gerais, Brazil and Chapada in Mato Grosso, Brazil, both of which are on care and maintenance, as well as 100% interest in the gold deposit at Braúna and other kimberlite projects.

Company Highlights

Braúna Project

On March 4, 2011, Vaaldiam entered into an arrangement with the joint venture partners of the Braúna project to restructure the existing arrangement and to increase the ownership interest of the Company in the Braúna project from 20% to 51% by paying a transaction consideration of US$6.5 million over 15 months to the existing partners and financing the project development cost to production. Vaaldiam is the operator for the project. See press release of March 4, 2011.

On April 7, 2011, Vaaldiam issued a National Instrument 43-101 ("NI 43-101") compliant Preliminary Assessment Report ("PA Report") which presented two net present valuations ("NPV") at a 10% discount rate and an independent diamond value of US$338 per carat ("ct"): a base case pre-tax NPV of US$33.6 million and internal rate of return ("IRR") of 42%, using the NI 43-101 mineral resource of diamond grade of 16.8 cts per 100 tonnes ("cpht") by Coffey Mining, and the second scenario of pre-tax NPV of US$101.0 million and IRR of 107% using the NI 43-101 mineral resource diamond grade of 24.58 cpht presented by A.C.A. Howe International in December 2010.

Duas Barras Mine

During the first quarter of 2011, a total of 4,355 cts of diamonds and 6.9 kilograms (221 troy ounces) of gold were recovered from 58,397 bank cubic metres ("bcm") at Duas Barras, resulting in an average diamond grade of 0.07 cts per bcm and an average gold grade of 0.12 grams of gold per bcm. These are much lower than the diamond resource grade of 0.16 cts per bcm and the gold resource grade of 0.18 grams of gold per bcm. With the escalating fuel costs and other operating costs, and the lower than expected grades, Vaaldiam made the decision in April to suspend operations at Duas Barras until such time that rising diamond prices may improve the mine's economics and make it reliably profitable. Until then, Vaaldiam will focus its attention on the Braúna project. As a result of suspending operations at Duas Barras in April, Vaaldiam reviewed the carrying value of Duas Barras mine for asset impairment at the end of the quarter and recorded an asset impairment loss of $6.1 million for the quarter ended March 31, 2011, representing the full carrying value of the mine and plant and equipment as at March 31, 2011.

Vaaldiam continues to pursue its strategy of using cash flow from disposing of non-core assets to sustain itself and to advance its high-potential hard rock diamond and gold properties in Brazil.

Cash Flow and Liquidity

As at March 31, 2011, Vaaldiam had working capital of $3.7 million, compared with $10.1 million at March 31, 2010. For the three months ended March 31, 2011, Vaaldiam used cash of $2.7 million, which included cash used in operations of $1.5 million, expenditures on plant and equipment and mine development of $0.3 million and payment of $0.9 million to the joint venture partners with respect to the Braúna transaction discussed above.
