Andina drills 266 m at 1.00 g/t Au, including 56 m at 2.6 g/t Au at Ojo De Agua East

TORONTO, May 25, 2011 - ANDINA Minerals Inc. (TSX-V: ADM) (the �Company�) today announced results from a second set of twenty (20) drill holes completed in 2011 at the Ojo de Agua East (�ODAE�) mineralized zone, situated at the Volcan Project site some 6.5 kms north-east 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 holes form part of the 10,000 metre (m) Strategic Exploration Program drilled during in the current field season. A further six (6) holes await assay results and are expected to be released in early June.

Hole RODAE-887D returned 1.0 grams per tonne gold (�g/t Au�) over 266 meters (�m�), including 54 m at 2.6 g/t Au. Hole RODAE-887D was reverse circulation pre-collared to a depth of 150 m and followed up with a diamond drill to a total depth of 450.65 m. Our objective to extend the known ore shoot to depth and to the South was successfully achieved.

�Hole RODAE-887D demonstrates down-dip continuity of increasing high-grade mineralization at ODAE and supports our continued belief that we have intercepted a structurally controlled mineralized system at ODAE.

With this hole we now have several intercepts of at surface mineralization, continuity to depth and at significantly higher average grade than the main Volcan resource grade.

ODAE could become an important resource, in the initial years of Volcan�s operations by allowing the displacement of low-grade fines, from the mill, to the heap leach pad and thereby replacing low-grade mill feed with high-grade ore� stated George Bee, President and CEO of Andina. �This hole is very encouraging as ODAE could materially improve Volcan�s cash flow in the initial years of operation. Therefore, we are moving quickly to process ODAE drilling results with a view to incorporating ODAE into the Volcan mine plan. We hope to release an initial resource estimate for ODAE in Q3�.

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

All holes released today consisted of a combined reverse circulation pre-collar with a diamond drill finish.

Results to Date and Geology

Andina has concluded the current 2010/2011 field season with a total of 10,831.7 m drilled in 33 holes. Total drilling at ODAE now stands at 13,207.15 m in 43 drill holes.

Our testing has confirmed a total strike length for the ODAE exploration target of over 750 m. We estimate that the mineralized zone extends up to a width of 200 m and a depth of 400 m. Current positive results include mineralization at the northern extension of ODAE (section 30) holes RODAE-923 and RODAE-924), while hole RODAE-887D increased the known ore body width significantly at the southern end of the mineralized zone. The high-grade core of hole RODAE-887D being 54 m @ 2.6 g/t Au coincides with earlier reported high-grade intercepts 100 - 200 m to the north at holes 851 and 853 (see section 22 and 23). (See press release dated February 15th 2011 for geology.)

Another important parameter, requiring additional investigation, is the presence of an approximately 150 m deep oxidized zone at ODAE, which offers potential for higher recoveries and lower costs in a standard heap leach process.

Andina will undertake an initial resource calculation once results for the remaining seven (7) holes are available, expected by early June, and will work towards an initial resource estimate for ODAE in the 3rd quarter of 2011.

With the success of targeting and discovering high-grade mineralization at ODAE, Andina is now considering expanding its regional exploration program to focus on other opportunities, such as ODAE, where it hopes to generate additional Diatreme hosted gold targets that could deliver high-grade gold mill feed for the Volcan Project.

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 D�az, Andina�s Qualified Person under National Instrument 43-101 and he is the Public Registered Person for Reserves and Resources N� 51, in Chile, also registered in the Colegio de Ge�logos de Chile under N� 315. Mr. D�az is responsible for preparing technical information on the Ojo de Agua East area.

QA/QC Protocols

Mr. D�az 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 contained in 283 million tonnes of ore. In addition, there remains 2.3 million ounces of Measured and Indicated gold resources at an average grade of 0.66 g/t contained in 107 million tonnes of ore plus 1.2 million gold ounces in the Inferred category. Andina is progressing with a feasibility study for Volcan, targeted for completion in the first half of 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.
