OTTAWA, ONTARIO--(Marketwire - June 28, 2010) - Mazorro Resources Inc. ("Mazorro" or the "Company")(TSX VENTURE:MZO)(FRANKFURT:JAM) announces initial sample results and exploration plans on its two Democratic Republic of Congo exploration permits, PR7811 and PR8500.

Random samples recently taken from permits PR7811 and PR8500 were submitted to ALS Chemex labs for 41 multi element assay tests (ME-MS41). Results for 10 grab rock samples include trace amounts of gold to a high of 6.4 grams per tonne (g/t) (ppm), with sample 7811-1 at 6.4 g/t, and sample 7811-2 at 3.1 g/t. Sample 7811-1 yielded an anomalous Antimony value of 1,345 ppm and sample 7811-3 yielded 243 ppm Zinc.

The Company has also received results for 3 soil samples taken at PR8500 during a recent field visit by Wardell Armstrong International in connection with their preparation of the Company's recently filed National Instrument 43-101 Report (available at [ www.SEDAR.com ] under the Company's profile). Sample 8500-2 yielded 7.3 g/t gold and sample 8500-3 yielded 18.5 g/t gold by MS-multi elements ME 41 tests. The size of the samples tested makes the results semi-quantitative. The soil samples 8500-2 and 8500-3 were retested by ICP21 fire assay analysis and yielded ore grade assays of 7.25 g/t and 9.46 g/t gold, respectively. Results of 2 soil samples taken at PR7811 showed elevated ore grades of gold. Sample 7811-1 exceeded ME-MS41 gold test limits and was re-tested and confirmed by 2 independent fire assay tests with the Fire Assay Gradient 21 test yielding 108.5 g/t gold, and sample 7811-2 yielding 9.41 g/t in fire assay ICP21 analysis.

These initial results warrant a detailed grid based sampling program be conducted to investigate these random sampling anomalies.

The Company plans to undertake a pre-field exploration survey of orientation data which have been obtained from The Royal Museum for Central Africa (RMCA) at Tervuren, Belgium. The data will be reviewed and investigated further in order to generate a compilation of exploration, resource/reserve and production information. Contingent on positive results from this phase, targets for initial exploration will be identified. Following the RMCA compilation study, the Company plans to engage preliminary stream sediment sampling and soil geochemistry programs to define any anomalous mineralisation within the permit areas. Surveying and sampling of any accessible exploration pits, trenches, mining sites, or artisanal workings will be undertaken. Additionally, the Company plans to field check and sample previously identified circular features from an ACA Howe Aster survey conducted in 2008 to establish whether these features are related to post-Kibaran granites which appear to be associated with mineralisation.

Some statements in this release may contain forward-looking information. All statements, other than of historical fact, that address activities, events or developments that the Company believes, expects or anticipates will or may occur in the future (including, without limitation, statements regarding potential mineralization) are forward-looking statements. Forward-looking statements are generally identifiable by use of the words "may", "will", "should", "continue", "expect", "anticipate", "estimate", "believe", "intend", "plan" or "project" or the negative of these words or other variations on these words or comparable terminology.

Factors that could cause actual results or events to differ materially from current expectations include, among other things, without limitation, failure to establish estimated mineral resources, the possibility that future exploration results will not be consistent with the Company's expectations, changes in world gold markets or markets for other commodities, and other risks disclosed in the Company's public disclosure record on file with the relevant securities regulatory authorities. Any forward-looking statement speaks only as of the date on which it is made and except as may be required by applicable securities laws, the Company disclaims any intent or obligation to update any forward-looking statement.
