Andina Establishes a New Resource at the Ojo de Agua East Area of the Volcan Gold Project

   ANDINA Minerals Inc. (TSX VENTURE: ADM) ("Andina") is pleased to report an initial resource estimate from the new Ojo de Agua East ("ODAE") area of the Volcan Gold Project ("Volcan").

The ODAE resource estimate includes indicated resources of 2.71 million tonnes grading 1.55 grams per tonne gold ("g/t Au") for contained gold of 135,000 ounces and inferred resources of 3.43 million tonnes grading 1.53 g/t Au for contained gold of 168,000 ounces, both at a 0.9 g/t Au cut-off grade.

The ODAE deposit is located in Chile's Maricunga Mineral Belt, approximately four kilometres northeast of the proposed process facilities for Volcan and within 1.5 kilometres of the proposed Volcan Heap Leach Pad.

Table 1 provides further details on the ODAE resource estimate while the accompanying sections highlight the better grade zone.

(1) All quantities are rounded to the appropriate number of significant
figures, consequently sums may not add up due to rounding.

(2) Mineral resources, which are not mineral reserves, do not have
demonstrated economic viability. The estimate of resources may be materially
affected by environmental, permitting, legal, title, taxation, socio-
political, marketing or other relevant issues.

(3) The quantity and grade of reported Inferred Resources in this estimation
are conceptual in nature and there has been insufficient exploration to
define these Inferred Resources as an Indicated Resource. It is uncertain if
further exploration will result in the upgrading of the Inferred Resources
into an Indicated or Measured Mineral Resource category.

"We are pleased to announce this initial gold resource for ODAE" stated George Bee, President and CEO of Andina. "The ODAE discovery is significant insofar as there is a higher grade core within ODAE which is a discernable unit, that can be mined and add higher grade material to the Volcan mine plan. What we see in ODAE is proof positive that Andina's land position hosts more gold than we knew about and the opportunity for higher grade material is now clear".

Mr. Bee went on to say, "With this shallow higher grade discovery at ODAE, we will assess if it is warranted to increase Volcan's proposed throughput to accommodate additional mineralization that could improve cash flow in the initial years of Volcan's operations."

With the addition of the ODAE resource estimate, total Volcan property reserves and resources are as follows:

--  Proven and Probable reserves remain unchanged at 6.6 million ounces of
    gold (283 million tonnes grading 0.73 g/t Au),
--  Measured and Indicated resources increased to 2.4 million contained
    ounces of gold (110 million tonnes grading 0.68 g/t Au), while,
--  Inferred resources increased to 1.35 million ounces of gold (64 million
    tonnes grading 0.66 g/t Au).

A summary of the total Volcan property resource estimate is provided in Table 2.

(6) 'Proven and Probable Reserves are based on a processing plan that
includes a Mill and a Heap Leach. The Mill cut-off grade used is 1.25 g/t
Au, while the Heap Leach cut-off grade is 0.34 g/t Au

(7) Due to the variable metallurgical recovery used in the determination of
the potential profitability of any given block within the block-model, an
iterative approach was required to determine cut-off grade(s) for Volcan's
Dorado (East, West and Central) deposits. Cut-off grades were determined for
each deposit that considered the full operating costs for both milling and
heap leach operations. Mill cut-off grades are 1.10 g/t Au, while Heap Leach
cut-off grades are 0.34 through 0.68 g/t Au. For purposes of the mineral
resource estimate, a gold price of US$950/oz Au was selected.

Geology and Exploration Drilling

ODAE is a structurally controlled gold target. Gold mineralization in the zone has been traced by drilling over a north-south strike length to approximately 750 m. The central higher grade zone is interpreted as a deep rooted sub-circular diatreme the core of which 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 dilatational zone and secondary north-west structures to develop. The best grades are located at the core of the diatreme and which extends to a total depth 400 m and which appears to be open at depth. Outside the diatreme, the total width of the structural corridor is in the order of 50 m.

The higher gold grades obtained at ODAE in comparison with the main deposits of Volcan, are characteristic of this Diatreme type of gold deposit.

Andina is currently reviewing the 2011/12 exploration campaign in order to assess an infill drilling program to achieve a 50 m by 50 m grid in order to enhance the resource categorization.

Resource Estimation Methodology

The ODAE resource estimation is based on 38 drill holes totaling 12,730.65 m of combined reverse circulation and diamond drilling. The drilling was performed on a 50 m by 100 m grid to an approximate depth of 500 m.

The resource was estimated using a block-model methodology. Drill hole assays were composited from (typically) two metre assay intervals to generate composite intervals for each drill hole which correspond to the appropriate cut-off grades which range from 0.3 to 1.0 g/t Au. Only drill intervals six metres long or greater, or greater than an approximate three metre true width, at or above the appropriate cut-off grade were included in the resource estimate. The maximum vertical projection was 100 meters as supported by the geology. The resource blocks were projected one half the distance between sections, or 25 metres northwest and southeast. A density of 2.34 tonnes per cubic metre was used, based on 77 density measurements on core drill samples.

Inferred resources are based on data which is not sufficiently closely spaced, or of sufficient quantity, that the geological and grade continuity can be reasonably assured with a sufficiently high level of confidence to allow the resources to be classified with a higher degree of certainty. It cannot be assumed that the Inferred Mineral Resources will be upgraded to an Indicated Resource as a result of continued exploration. Additionally, it cannot be assumed that the Indicated Mineral Resources will be upgraded to a Measured Resource as a result of continued exploration.

Furthermore, it cannot it be assured that measured and indicated or inferred mineral resources will be converted to a "reserve" category at such time as feasibility studies are initiated.

Map and sections showing all drill results to date from ODAE may be found at the end of this press release.

Quality Assurance / Quality Control Program

Mr. Michael Easdon, a "qualified person" as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101"), 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 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 did not use either the chip channel (trenching) or grab samples data in the 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 Asesoria Minera Geoanalitica Limitada ("Geoanalitica") sample preparation facility in Copiapo Chile, where they are crushed (chip and grab samples) and which 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 50 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.
