Trade Winds Ventures Completes 
Preliminary Metallurgical Study on Block A

Vancouver, BC, May 2, 2011 - Trade Winds Ventures Inc. (TSX-V: TWD, FSE: TVR) ("Trade Winds") is pleased announce the results of a metallurgical study by SGS Minerals Services ("SGS") on the Block A Joint Venture project (50% Trade Winds / 50% Detour Gold), located adjacent to Detour Gold's Detour Lake gold project in northeastern Ontario. Trade Winds is currently the operator of the JV on Block A.

The study completed by SGS Minerals Services ("SGS") of Lakefield, Ontario was designed and supervised by Mr. Andy Holloway, Senior Associate Process Engineer of Watts, Griffis and McOuat Limited ("WGM"). Results indicate excellent gold recoveries, ranging from 87.3% to 98.7%, using a standard gravity/cyanidation/carbon-in-pulp circuit (see table below).  Three composite samples were prepared from diamond drill hole TWDDH253 (section 16460E) drilled in early 2010 near the centre of the deposit and submitted to SGS for a preliminary metallurgical study including grindability assessment (Bond ball mill work index), gravity separation and bottle roll cyanidation tests.

The Bond ball mill work index results varied from 9.0 to 10.2 kWh/t, indicating a low degree of hardness.  Further testing will be required on a number of samples to adequately represent the deposit.  Gravity gold recoveries were 72% for Composite 1, 20% for Composite 2, and 80% for Composite 3.  With subsequent cyanidation of gravity tailings, the overall gold recovery ranged between 87% and 98.7%, depending on grind size and NaCN concentration.  Bottle roll cyanidation tests were conducted at 8, 24, 32 and 48 hours intervals.  The tests do conclude that higher overall gold recoveries can be achieved with the inclusion of a gravity circuit .

Further metallurgical and comminution work will be undertaken in 2011 along with detailed mineralogical studies to determine the nature of the gold.

Forward Looking Information
Certain information included in this news release constitutes "forward-looking statements". The words "expect", "will", "intend", "estimate" and similar expressions identify forward-looking statements. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by management, are inherently subject to significant business, economic and competitive uncertainties and contingencies. The Company cautions the reader that such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the Company to be materially different from the Company's estimated future results, performance or achievements expressed or implied by those forward-looking statements and the forward-looking statements are not guarantees of future performance. These risks, uncertainties and other factors include, but are not limited to, risks associated with the mining industry such as government regulation, environmental and reclamation risks, title disputes or claims, success of mining activities, future commodity prices, costs of production, possible variation in mineral reserves, mineral resources, grade or recovery rates, failure of plant, equipment or processes to operate as anticipated, accidents, labour disputes, the timing of estimated future production, capital expenditures, financial market fluctuations, requirements for additional capital, conclusions of economic evaluations, limitations on insurance coverage, risks associated with using third-party contractors and inflation. The Company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise, except as required by applicable law.

Information Concerning Estimates of Mineral Resources
This news release uses the terms 'indicated' and 'inferred' resources. The Company advises investors that although these terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, 'inferred resources' have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.

 

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
