TORONTO, Feb. 22 /CNW/ - Medoro Resources Ltd. (TSX-V: MRS) is pleased to announce that it has received a National Instrument 43-101 compliant technical report on its Zona Baja property (the "Zona Baja Report"), recently acquired through the acquisition of Mineros Nacionales S.A. The Zona Baja Report contains mineral resource estimates of 3.4 million ounces of gold in the measured and indicated categories with an additional 1.3 million ounces of gold in the inferred category. The estimates are based on 17,372 meters of diamond drilling in 78 holes and using a cutoff grade of 0.3 g/t Au.

Zona Baja is located at Marmato in Colombia, directly beneath and contiguous with the Company's Zona Alta property, and it adjoins Medoro's Echandia property. The Company has now received NI 43-101 technical resource estimate reports on all three of these properties and the measured and indicated resource estimates for the three properties total approximately 6.87 million ounces of gold. The inferred resource estimates for the three properties total approximately 2.66 million ounces of gold. (See tables below.)

"Medoro now has a very strong position at Marmato with M&I gold resources of over 6.8 million ounces and an operating underground gold mine. Our plans are to expand, upgrade and combine these mineral resources while seeking methods to improve efficiency and increase production at the mine," said John Hick, CEO of Medoro Resources Ltd.

The Zona Baja Report describing the resource estimate is filed on SEDAR and can be accessed at www.sedar.com and on the company's website at www.medororesources.com.
