CHICAGO, IL--(Marketwire - June 21, 2010) -  Tara Minerals Corp. (OTCBB: TARM) (BERLIN: 6T3) is pleased to announce the discovery of additional gold-bearing veins at the Picacho prospect of its subsidiary, Adit Resources Corp. The discoveries consist of a new vein system parallel to the previously drilled Picacho Vein target, two new veins in the Dos Amigos target, and two new parallel veins in the No Name target. Initial sampling has identified areas grading more than our targeted future production grade of 5 grams of gold per tonne and the identification of parallel veins is ideal for a scenario of mining multiple veins from common underground accesses. A total of nine gold-bearing veins have now been identified with an aggregate strike length of over 10.8 kilometers. Previous drilling has been conducted only along the Picacho Vein.

With the addition of 2.3 kilometers in new veins, the aggregate strike length of the Picacho prospect has increased from 8.5 kilometers to 10.8 kilometers over four mineralized target areas -- the Picacho Vein, Dos Amigos, Basaitegui, and No Name. The near term plan is to aggressively core drill the Picacho Vein where previous drilling results included true width intercepts of 11.3 meters of 15.6 gpt-gold and 9.4 meters of 7.8 gpt-gold. Simultaneously, detailed surface evaluation (mapping, geochemical sampling, trenching) of the other three areas will be conducted to identify targets for a reverse circulation drill campaign later in the year.

The property is being re-surveyed to an accuracy of one meter. This enables Adit to get all of the previous data into a three-dimensional database and greatly enhances geologic mapping. Initial results of current efforts are summarized below.

Mr. Robert Wheatley, President of Adit Resources Corp., commented, "The dedicated efforts of our experienced and motivated geologists are already paying off with the identification of additional veins. I would like to thank our geologists and local technicians for their efforts. The potential of the Picacho property continues to grow. We are now planning a drill program, with initial focus on the Picacho Vein target area, which will begin to unlock this potential for the benefit of our shareholders."

Picacho Vein Target Area

In order to test for potential near-surface open pit potential, surface channel sampling was completed in the central portion of the Picacho Vein above old mine workings. These results returned 15 meters averaging 1.46 gpt-gold and 6 meters averaging 0.92 gpt-gold. These encouraging results justify further advancement with more detailed channel sampling and future shallow drilling.

Geologic reconnaissance identified a new mineralized target consisting of veins, stockworks, and breccias along a 1.3 kilometer structure that is 200-250 meters south of and parallel to the Picacho Vein. The western, highest elevation portion of the zone displays textures indicative of the highest levels of a vein system as well as parallel mafic dikes correlative with the dikes seen in the productive portions of the Picacho Vein; a dump grab sample contained 1.25 gpt-gold. On the eastern portion (130 meter lower elevation) samples up to 1.8 meters grading 3.54 gpt-gold were obtained.

Preliminary work on the western end of the mined portion of the Picacho Vein indicates a northeast trending, 50-100 meter offset. Veinlets along this zone returned anomalous gold values.

Dos Amigos Target Area

Reconnaissance and topographic mapping reveals that the area between the previously mapped two parallel veins contains at least two more veins totaling at least 200 meters of strike length. Sampling of these well banded chalcedony veins is being initiated. There has been no known previous drilling in this area.

Basaitegui Target Area

Reconnaissance along the Basaitegui Vein has extended the strike length by at least 150 meters. A 1.2 meter channel sample returned 43.5 gpt-gold. Quartz replacing calcite is common in the area. There has been no known previous drilling in this area.

Sin Nombre (No Name) Target Area

Reconnaissance mapping and sampling reveals there are at least three parallel veins instead of just two veins as previously mapped. Thirty-eight samples collected average 2.86 gpt-gold with values up to 1.9 meters of 10.05 gpt-gold. Over 800 meters of additional vein strike length were identified. There has been no known previous drilling in this area.
