Andina Drills 104 m at 2.21 g/t Au, Including 30 m at 3.98 g/t Au at Ojo de Agua East

   ANDINA Minerals Inc. (TSX VENTURE: ADM) (the "Company") today announced results from the first six (6) completed drill holes in 2011 at the Ojo de Agua East ("ODAE") mineralized zone, situated at the Volcan Project site some 6.5 kms from the known Dorado zone and approximately 4 kms to the north of the proposed Mill and Heap Leach Pad in the Volcan Phase 1 Development Plan. These completed holes are from the 10,000 metre (m) Strategic Exploration Program in the current field season.

The ODAE zone is part of the mineral concessions acquired from Barrick Gold Corporation in 2009.

Four (4) of the six (6) completed holes consist of combined reverse circulation pre-collars with a diamond drill finish (see Table 1).

Results of the drill hole are as follows:

Hole RODAE-853 returned 2.2 grams per tonne gold ("g/t Au") over 104 m, including 30 m at 3.98 g/t Au. Hole RODAE-853 was pre-collared to a depth of 132 m and followed up with a diamond drill to a total depth of 539.15 m. The objective was to intercept the down-dip continuity of hole RODAE-851 which intercepted 122 m of 1.45 g/t Au in the previous 2009/2010 field season (see press release June 8, 2010). The results extend the ore shoot an additional 100 m, to a depth of 300 m, and increase the grade of the zone.

Along what was considered to be a northerly strike continuity of the known mineralized zone, Andina tested at 100 m intervals and this resulted in hole RODAE-861 intercepting 144 m at 0.51 g/t Au and hole RODAE-856 intercepting 38 m at 0.464 g/t Au, while hole RODAE-854 to the south did not intercept mineralization. Hole RODAE-857, a reverse circulation hole collared into the northeastern 100 ppb geochemical halo, with the objective to test for oxidized ore, did not return positive results.

An important parameter, requiring additional investigation, is the presence of an approximately 150 m deep oxidized zone at ODAE.

"Hole RODAE-853 demonstrates down-dip continuity of increasing high-grade mineralization at ODAE and supports our belief that we have intercepted a structurally controlled mineralized system at ODAE with significantly higher average grades than the main Volcan deposits. This could meaningfully impact Volcan's development plan and economics as we prepare a feasibility study for Volcan during 2011" stated George Bee, President and CEO of Andina. "This additional result provides an excellent opportunity to supplement our existing mill feed with higher grade than is contemplated in our Phase 1 Development Plan".

Results to Date and Geology

Andina has drilled 13 successful holes to date into the structural gold target at ODAE. Its north-south trending corridor has now been traced over 750 m; of which 500 m are drill indicated, while another 250 m can be inferred from new trench results cutting the corridor. These trenches show 100 m of 54 ppb gold, a strong indicator for continuity of ODAE towards a northerly direction.

The central higher grade zone however, is interpreted as a deep rooted sub-circular diatreme whose central core is located around holes RODAE-853 and RODAE-861.

This diatreme is characterized by phreatomagmatic breccias, indicating near surface explosive events. Its dimensions are approximately 200 m by 150 m and it appears to have used the north-south dilational zone and secondary north-west structures to develop. Best grades are located at its core and its total depth may well extend to greater depth. Total width of the structural corridor outside the diatreme is in the order of 50 m.

Diatreme hosted gold deposits are common features in high level gold environments such as the Volcan district and are characterized by higher grades than parent porphyry hosted deposits.

In addition to ODAE, Andina is also focusing its regional exploration program on other opportunities such as ODAE to generate Diatreme hosted gold targets with the objective to deliver higher grade gold sources to the Volcan Project.

Andina plans to complete definition drilling to further define the potential at ODAE at 50 m sections in the central zone and will delineate continuity towards the North.

Andina anticipates an initial resource estimate for ODAE in the 3rd quarter of 2011.

Ojo de Agua East Area Qualified Person

The trenching and drilling program at the Ojo de Agua East area of the Volcan Gold Project was reviewed and the results approved by Mr. Sergio Diaz, Andina's Qualified Person under National Instrument 43-101 and he is the Public Registered Person for Reserves and Resources No 51, in Chile, also registered in the Colegio de Geologos de Chile under No 315. Mr. Diaz is responsible for preparing technical information on the Ojo de Agua East area.

QA/QC Protocols

Mr. Diaz has confirmed that Andina has utilized appropriate and accepted (per National Instruments 43-101 requirements) Quality Assurance and Quality Control ("QA/QC") protocols for the trench and drill hole sampling and assaying. Grab samples are selected pieces of rock collected to identify or confirm anomalous or potentially economic concentrations of precious metals (Au, Ag), base metals (Cu, Mo, Zn, Pb), as well as path-finder elements commonly associated with epithermal mineralization (As, Sb, Hg, Ba). Chip-channel samples are one or more continuous samples of mineralized or altered rock collected with hammer and chisel over a measured interval and may be taken from areas of outcrop or from trenches. Sample locations are determined at the time of collection with handheld GPS readings. Andina does not intend to use either the chip channel (trenching) or grab samples data in any future resource estimations. The samples that were taken in this program have been collected to confirm previously reported exploration sampling results and to further identify areas of greater interest for more detailed future exploration and drilling.

All samples are delivered by the Company's personnel to the Geoanalitica sample preparation facility in Copiapo Chile, where they are crushed (chip and grab samples) and all drill hole and surface samples are then shipped by Geoanalitica to their assay facility located in Antofagasta. Geoanalitica analyzes the samples for gold, copper and molybdenum. The gold assays are performed utilizing 30 g fire assay with an Atomic Absorption Spectroscopy ("AAS") or gravimetric finish; the Cu and Mo are assayed for using standard wet analytical techniques. Sample pulp splits are subsequently sent by Geoanalitica to the ALS-Chemex laboratory (also in Coquimbo) for multi-element Inductively Coupled Plasma ("ICP") analysis.

About Andina Minerals Inc.

Andina's primary focus is mining exploration and development in Chile. The Company's flagship development project is the 100%-owned Volcan Gold Project ("Volcan"), strategically located in the prolific Maricunga Gold Belt. In February 2011, Andina announced the results of a positive pre-feasibility study for Volcan. Initial Proven and Probable Mineral Reserves are 6.6 million ounces of gold at an average grade of 0.73 g/t gold. In addition, there remains 2.3 million of Measured and Indicated gold resources plus 1.2 million gold ounces in the Inferred category. Andina is progressing with a feasibility study for Volcan, targeted for completion in 2012.

In addition to Andina's extensive underexplored land position surrounding Volcan, the Company holds two other mineral properties located within Chile's primary mining regions.
