Medoro Announces Additional Drilling Results
TORONTO, ONTARIO--(Marketwire - Oct.

18, 2010) - Medoro Resources Ltd.

(TSX VENTURE:MRS) announced today diamond drilling results from a further 19 drill holes from its exploration and in-fill drilling program at the Marmato gold project in Colombia.

Highlights included Hole MT-1282 which intersected 215.5 metres (m) at an average gold grade of 1.0 grams per tonne (g/t), and Hole MT-1283A which reported a 37.2 metre interval grading 3.9 g/t gold. Serafino Iacono, Interim President and CEO of Medoro, commented, "We are very pleased with the consistently good results we are generating from this drill program, which demonstrate economic gold grades over significant widths.

Marmato is a significant bulk tonnage gold project which is distinguished by its access to excellent infrastructure, an existing operational mine and mill, and topography which will facilitate the construction of a large tonnage, open pit mining operation." Other significant results (greater than 10 gram-metres) are summarized below.

Sample lengths are normally 2.0 metres but may be varied for geological and recovery factors.

Intersections were calculated using a cut-off grade of 0.1 g/t gold and no more than 6.0 metres of internal dilution.

Gold grades were cut to 20.0 g/t.

No significant intercepts in holes MT-1280, 1281, 1291, 1294 and 1303 were found.

---------------------------------------------------------------------------
In addition to the long widths of low grade mineralization, several drill holes also contain high grades of gold and silver in both veins and in porphyry with veinlets, with gold values of up to 72.8 g/t over 1.3 metres and silver values of 88.0 g/t over 0.8 metres. The total number of metres drilled to date is 46,870 in 136 holes, including 23 holes for which the company is awaiting assay results and 12 holes which are currently being drilled.

All of the results to date, together with a map showing the locations of the drill holes, are available on Medoros website at www.medororesources.com. The Marmato Project is a single gold deposit comprised of the three contiguous license areas of Zona Alta, Echandia and Zona Baja, which cover 1,198 hectares in Caldas, Colombia.

The Marmato Project is the subject of a Technical Report dated March 5, 2010 prepared by Scott Wilson of Scott E. Wilson Consulting, Inc.

of Englewood, Colorado which currently has a measured and indicated mineral resource of approximately 245 million tonnes at an average gold grade of 1.0 g/t containing 7.5 million ounces of gold plus 76 million tonnes grading 0.9 g/t containing approximately 2.2 million ounces of gold classified as inferred resources.

Verification included a review of the quality assurance and quality control samples, and review of the applicable assay databases and assay certificates. Quality Assurance and Quality Control In the case of the drilling results referred to herein, the samples were prepared by Acme Analytical Laboratories Ltd (ISO 9001:2008) at their sample preparation facility in Medellin, Colombia, and were assayed at their laboratory in Santiago, Chile.

Gold was assayed by fire assay with atomic absorption spectrophotometer ("AAS") finish.

Samples over 10 g/t were assayed by fire assay with gravimetric finish.

Silver was assayed by aqua regia digestion and AAS finish.

Silver samples above 100 g/t were assayed by fire assay with gravimetric finish.

Blank, standard and duplicate samples were routinely inserted for quality assurance and quality control. About Medoro Resources Ltd. Medoro Resources Ltd.
