MONTREAL, QUEBEC---(Marketwire - Feb. 24, 2010) - Strateco Resources Inc. ("Strateco") (TSX:RSC)(OTCBB:SRSIF)(FRANKFURT:RF9) is pleased to announce an update of the Preliminary Assessment of its 100% owned Matoush property located in the Otish Mountains, 275 km north of Chibougamau, Quebec.

The revision of the Preliminary Assessment was conducted by Scott Wilson Roscoe Postle Associates Inc. ("Scott Wilson RPA"), with the participation of Melis Engineering Ltd. for capital and processing costs.

The revised Preliminary Assessment is based on the National Instrument 43-101 compliant indicated and inferred resource estimate made by Scott Wilson RPA in September, 2009.

Mineral Resource Estimate for Matoush, September 1st, 2009 Tonnes Grade Pounds U3O8 (x 1,000) (% U3O8) (x 1,000) ---------------------------------------------------------------------------- Indicated AM-15 262 0.70 4,039 MT-34 174 0.89 3,420 ---------------------------------------------------------------------------- Total Indicated 436 0.78 7,458 Inferred AM-15 33 0.34 249 MT-22 822 0.53 9,526 MT-34 302 0.45 3,003 ---------------------------------------------------------------------------- Total Inferred 1,157 0.50 12,777

Notes:

1. CIM Definition Standards have been followed for classification of Mineral Resources. 2. The cut-off grade of 0.1% U3O8 was estimated using a U3O8 price of US$75/lb and assumed operating costs. 3. High U3O8 grades were cut to 9%. 4. The Mineral Resource estimate uses drill hole data available as of September 1, 2009. 5. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. 6. Totals may not sum correctly due to rounding.

The following is a summary of the Preliminary Assessment results (conducted on February 2010). The updated report will be available on Strateco's website (www.stratecoinc.com) and on SEDAR (www.sedar.com) within 45 days.

The Preliminary Assessment is based, in part, on inferred resources, and is preliminary in nature. Inferred resources are considered too geologically speculative to have mining and economic considerations applied to them and to be categorized as Mineral Reserves. There is no certainty that the reserves development, production and economic forecasts on which this preliminary assessment is based will be realized.

I PRODUCTION AND RECOVERED METAL

The mining plan was based on mineral resources with factors applied for dilution and extraction. Recovered metal is based on metallurgical tests done at SGS Lakefield Research Ltd. in Lakefield, ON; an average of 97.6% recovery is used. Potential grade implied mining dilution at 15% at zero value. Mill design was modified to increase annual mill capacity from 2.0 M to 2.7 M pounds U3O8.

II REVENUE

-- The price scenario was established by SD Energy in September 2008, in the initial scoping study, with a long term price from US$60.00 to US$90.00 per pound U3O8 over the life of the project with an evaluation price of US$75.00 per pound U3O8. -- The exchange rate US$/CAN$ is 0.85. -- Transport to smelter in North America is $0.10 per pound. -- Royalty 2%. ------------------------------------------------------- (x 1,000) CAN$ ------------------------------------------------------- Gross Revenue 1,568,363 ------------------------------------------------------- Transport to smelter 1,777 ------------------------------------------------------- Royalty 31,332 ------------------------------------------------------- NSR Gross Revenue after the Royalty 1,535,253 -------------------------------------------------------

"Regardless of the significant inflation in operating costs in the mining industry, our Matoush project indicates stronger economics, compared to the initial scoping study. Despite a possible price decrease, it is still possible to see our economics improve. We continue to evaluate different engineering alternatives to enhance the project's economics, such as the use of windmills to produce electricity. Closure costs were kept to $30 Million, work will be done to reduce this important cost," says Mr Guy Hebert, President and CEO. "We continue to expand mineral resources with an aggressive drilling program of 120,000 meters over the next 24 months," continues Mr. Hebert.
