Medoro Announces Preliminary Resource at Lo Increible Properties

TORONTO, Nov. 1 /CNW/ - Medoro Resources Ltd. announced today an Indicated Mineral Resource at the La Cruz, La Sofia and El Tapon zones at its Lo Increible 4A and 4B properties in Venezuela of 394,000 ounces of gold comprising 5.9 million tonnes at an average gold grade of 2.1 grams per tonne (g/t). In addition, an Inferred Mineral Resource of 423,000 ounces was identified comprising 5.6 million tonnes grading 2.4 g/t.

Based on 296 diamond drill holes, 186 of which were drilled during2006-2007, totaling 45,084 metres, and 24 historical reverse circulation holestotaling 3,900 metres, the Inferred and Indicated Mineral Resources based on acut-off grade of 0.5 g/t have been estimated as tabulated below. All gradeinterpolation has been carried out using Ordinary Kriging and all figures arenet attributable. Indicated Inferred Tonnes Grade Ozs Tonnes Grade Ozs ----------------------- ----------------------- La Cruz O/P 4,130,000 2.2 292,000 2,230,000 2.2 158,000 U/G - - - 240,000 6.4 49,000 La Sofia O/P 1,760,000 1.8 102,000 607,000 1.7 33,000 El Tapon O/P - - - 2,470,000 2.3 183,000 ----------------------- ----------------------- Total 5,890,000 2.1 394,000 5,547,000 2.4 423,000

Drill holes are to a maximum depth of 450 metres (historical drill hole) and 367 metres (2006-2007 campaign) and have an average depth of 153 metres. The drill grid is based on 50x50 metre spacing, except at La Cruz, where it has been 25x25 metres.

The company currently has three drill rigs on the property, of which one is dedicated to continuing to upgrade the resources at the La Cruz, La Sofia and El Tapon zones. The other two rigs are evaluating three additional prospects, among others, that have been identified within Lo Increible 4A and 4B - Tibaire, Mina A, and La Loca.

This resource estimate has been prepared to update the previously reported historical resources to current National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") standards. While no detailed economic studies have yet been carried out to determine what portion of these mineral resources will ultimately be upgraded to Mineral Reserves, sufficient work has been undertaken to confirm that these are potentially economic and can therefore be reported as mineral resources as defined by the standards adopted by the CIM Council.

Mike Armitage is the Qualified Person for this project, is independent of the company, and has reviewed the resulting mineral resource estimates and the integrity of these as reported above. A NI 43-101 compliant Technical Report is being prepared on these resources and will be filed by the company shortly.

Medoro has used Triad Laboratories in Venezuela as the primary laboratory. Split HQ core samples of 4 to 5 kilograms were crushed and pulverized to 250 grams. A 50-gram sample was split for fire assay analysis using AAS finish, and gravimetric finish if gold grade was greater than 2.0 g/t. A comprehensive quality control program, which includes blanks, standards duplicates and cross checks was employed.

Medoro Resources is a gold exploration and development company focused on acquiring properties of merit for potential joint ventures with senior producers. The company holds a 100% interest in the Lo Increible 4A and 4B concessions in Venezuela and interests in nine gold exploration areas in the Republic of Mali.

Glossary:

Ordinary Kriging: Ordinary kriging (OK) is a geostatistical approach to modeling. Instead of weighting nearby data points by some power of their inverted distance, OK relies on the spatial correlation of the data to determine the weighting values. This is a more rigorous approach to modeling, as correlation between data points determines the estimated value at an unsampled point.

O/P: Open pit. U/G: Underground. Split HQ: A standard form of core size. THE TSX VENTURE EXCHANGE HAS NOT REVIEWED AND DOES NOT ACCEPT RESPONSIBILITY FOR THE ADEQUACY OR ACCURACY OF THIS NEWS RELEASE
