ANDINA Minerals Inc.: Drilling Outlines New Gold Zone at Volcan Gold Project

Ojo de Agua Area Drilling Returns 104 Metres Grading 0.81 g/t Gold

TORONTO, ONTARIO--(CCNMatthews - Feb. 20, 2007) - ANDINA Minerals Inc. (TSX VENTURE:ADM) ("Andina") is pleased to report the results from three reconnaissance drill holes from the Ojo de Agua area of Andina's Volcan Gold Project located in Chile's Maricunga Gold Belt. The drill results, which include a 104 metre interval grading 0.81 grams per tonne gold ("g/t Au"), confirmed the extension of gold mineralization below a series of trenches sampled in early 2006. Table 1 summarizes the results from the reverse circulation drill holes.

The Ojo de Agua area is located four kilometres northeast of Volcan's Dorado area where Andina continues to outline three gold deposits. Ojo de Agua is similar to the Dorado area in that both are underlain by large high-sulphidation alteration systems which host gold mineralization associated with breccia systems developed within diorite porphyries.

"While the primary focus of our ongoing 40,000 metre Volcan drilling campaign is directed towards increasing the resource base within the property's Dorado area, we are dedicated to evaluating new high priority targets such as the large Ojo de Agua alteration system", stated Carl B. Hansen, President and CEO of Andina. "Considering the success of the reconnaissance drilling, we are mobilizing a drill rig back into the Ojo de Agua area and are considering the addition of another rig during the second quarter."

The Ojo de Agua drill holes targeted anomalous zones of gold mineralization identified by Andina during the previous Phase II (2005/2006) exploration season. A summary of the drill results follows:

- RODA-630 - collared near the base of the acid-leached alteration zone, the hole returned 28 metres grading 0.54 g/t Au, confirming the down dip extension of a 40 metre interval grading 0.58 g/t Au obtained from trench TR-11 (see Andina press release dated March 14, 2006). Mineralization is associated with a polymictic breccia developed within a diorite with fine disseminated pyrite.

- RODA-634 - collared 150 metres southeast of RODA-630 and 50 metres lower, the hole cut a wide interval of gold mineralization, 238 metres grading 0.54 g/t including 104 meters grading 0.81 g/t Au (at a 0.5 cut off grade), similarly hosted in a polymictic breccia with minor pyrite. The hole was drilled to test the down-dip extension of the gold mineralization encountered in trench TR-1 which included a 205 metre interval that graded 0.67 g/t Au.

- RODA-637 - collared 550 metres southwest of RODA-630, the drill hole tested a 50 to 75 metre wide, locally silicified, fault zone which has been traced on surface over a strike length of approximately 2,000 metres and from which surface grab samples had returned assays up to 6.58 g/t Au. The drill hole confirmed the presence of gold mineralization at depth with a 54 metre interval grading 0.65 g/t Au. The mineralized interval was oxidized.

About Andina Minerals Inc.

Andina is an Americas-focused exploration company, with a portfolio of precious metals exploration projects in Chile, dedicated to maximizing the value of its exploration assets through a disciplined and fiscally responsible approach to exploration.

Mr. Micheal Easdon, a Registered Professional Geologist resident in Santiago, Chile and an "Independent Qualified Person" as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI43-101") is also the "Qualified Person" for the Volcan exploration program.

The reverse circulation ("RC") chips from Andina's Volcan drilling campaigns were collected at the drill under the direct supervision of Andina staff. RC samples of approximately 70 kilograms in weight were collected over 2 metre intervals. The RC samples were appropriately tagged, secured and transported to the Andina exploration camp and then to Andina's secure sample logging and preparation site near Copiapo, Chile. RC chip samples were riffle split twice to obtain a 15 kilogram sample for assay purposes. Representative chips were collected from each sample for logging purposes. All samples were appropriately tagged and securely stored prior to shipping to Asesoria Minera Geoanalitica Ltda.'s ("Geoanalitica") laboratory in La Serena, Chile.

Samples are processed and analyzed for gold using fire assay techniques with atomic absorption finish. Samples which returned gold values greater than 1.00 g/t Au are re-analyzed by Geoanalitica using fire assay techniques with a gravimetric finish. Duplicate samples are inserted at a rate of approximately 5%. Andina also inserts standard samples within each sample batch to ensure laboratory quality control procedures. Occasionally Andina requests that Geoanalitica send samples to ALS Chemex in La Serena, Chile for 47 trace element analysis using ICP.

A 43-101 compliant Technical Report titled "Technical Report on the Volcan Gold Project. Region III, Chile" filed November 2006 at www.sedar.com summarizes Andina's September 2006 Volcan resource estimate. Previous technical reports relating to the Volcan Gold Project have also been filed on the SEDAR web site. Further, all reports are available on the Company's website noted below.
