Gold Resource Estimates at Medoro's Marmato Project Increase to 7.5 Million
Ounces Measured and Indicated and 2.2 Million Ounces Inferred

TORONTO, March 8 /CNW/ - Medoro Resources Ltd. (TSX-V: MRS) is pleased to announce a new National Instrument 43-101 compliant resource estimate for its Marmato Project of measured and indicated resources containing 7.49 million ounces of gold and inferred resources containing 2.23 million ounces of gold. In addition, there is an estimated M&I resource of 48 million ounces of silver and an estimated inferred resource of 13.4 million ounces of silver (see the summary table below).

Medoro's Marmato Project includes three individual properties - Zona Alta, Echandia and Zona Baja - all of which were recently acquired by the Company through its purchase of the companies owning these properties. These individual properties are held under different licenses but are contiguous and are all part of the same geological system.

The updated resource estimates discussed in this press release cover the combined areas of Zona Alta, Echandia and Zona Baja. Resource estimates for each of the three separate areas were prepared and disclosed previously (see press release dated February 22, 2010). We are now able to consolidate the mineral deposit and have made this new resource estimate comprising a single project, the Marmato Project, rather than summing the individual resource estimates for the three properties.

The estimates are based on over 80,000 meters of diamond drilling in 379 holes and using a cutoff grade of 0.3 g/t Au.

"We are particularly pleased with this new resource estimate because the total M&I resource estimate of 7.49 million ounces of gold represents an increase of approximately 700,000 ounces over what was previously reported for the total M&I resources on the three individual properties. This is a result of the Company's successful consolidation strategy at Marmato," said John Hick, CEO of Medoro.

"As our substantial infill and exploration drilling program progresses, we expect further increases in resources. In addition, we are currently anticipating gold production from our underground Mineros Mine at Marmato to be about 25,000 ounces in 2010," he added.

The Company is currently conducting an exploration and infill drilling program aimed at further expanding and upgrading these gold resources. With 5 drills currently working, approximately 5,100 metres have been drilled since January 15, 2010. The first batch of assay results from this drilling program should be available for release shortly. Next steps include a scoping study to consider the possibility of a large scale open pit mine at Marmato, and a study of the potential for cost and/or production improvements at the Mineros underground mine located on Zona Baja.

Qualified Person:

Sample Preparation, Assays, QA/QC

The samples were prepared by Inspectorate America Corporation (ISO 9001:2000 and 9002:2004 certified) at sample preparation facilities in Medellin, Colombia, and Reno Nevada, and were assayed at their laboratories in Reno and Lima, Peru. Gold was assayed by fire assay with gravimetric or atomic absorption spectrophotometer ("AAS") finish. Silver was assayed by AAS finish or analyzed by ICP with a suite of multi-elements. Additional laboratories used were SGS Lakefield Research Ltd. in Medellin, Colombia (preparation) and Lima, Peru (analysis), and ALS Chemex in Reno, Nevada (analysis) using the same analytical methods. Blank, standard and duplicate samples were routinely inserted for quality assurance and quality control.
