Andina Continues to Extend West Zone Gold Deposit Along Strike

Widths Improving with 450 Metres Grading 0.62 g/t Au

TORONTO, ONTARIO--(CCNMatthews - April 19, 2007) - ANDINA Minerals Inc. (TSX VENTURE:ADM) ("Andina") is pleased to report that infill and extensional drilling from the Dorado West Zone deposit on the Volcan property continues to confirm and expand the dimensions of the gold mineralization with results including 450 metres grading 0.62 grams per tonne gold ("g/t Au") and 70 metres grading 1.74 g/t Au. Table 1, below, provides a summary of the significant drill results from this release while Table 2, attached, provides further details.

"The West Zone drilling program continues to exceed our expectations by extending the gold mineralization over significant widths to the northeast as well as confirming the extension of the mineralization to depth", said Andina President and CEO, Carl B. Hansen. "Currently, Andina is drilling the West Zone along strike to the northeast while working to determine the orientation of a new gold zone situated between the West Zone deposit and the NW Zone (ROA-675 - 186 metres grading 0.75 g/t Au). Upon completion of the current Phase III exploration campaign, scheduled for May 2007, work will commence on an updated resource estimate for release during the third quarter 2007."

Highlights

- Drill hole ROA-675 was collared on section 1150 to test a new zone of gold mineralization situated between the West Zone deposit and the NW zone which had been cut in drill hole ROA-624 (154 metres grading 0.68 g/t Au commencing at surface - see Andina release dated February 8, 2007). ROA-675 returned a 186 metre interval grading 0.75 g/t Au including a 22 metre section grading 2.36 g/t Au. Further drilling is necessary to determine the orientation and dimensions of the new gold zone.

- ROA-673, collared on section 1050, was drilled to a depth of 200 meters returning 150 metres grading 0.75 g/t Au including 48 metres at the end of the hole which returned 1.36 g/t Au. Presently, the West Zone is approximately 200 metres wide on section 1050 although ROA-673 has been deepened and it is anticipated that the width of the zone will increase. Assays are pending.

- On section 900, drill hole DOA-666, which returned 450 metres grading 0.62 g/t Au including 48 metres grading 1.15 g/t Au, increased the true width of the West Zone deposit to approximately 250 metres at a depth of 300 metres below surface. At surface, the gold deposit is approximately 200 metres wide. Drill hole ROA-678, (136 metres grading 0.58 g/t Au) defined the near surface south-eastern boundary of the mineralization.

- Drilling on sections 300 and 350 (see ROA-629D, DOA-663, and DOA-671 results on table 1) confirmed the depth extension of the West Zone gold mineralization previously cut by shallow drilling. Drill hole ROA-629D is the deepened extension of ROA-629 previously reported on March 29, 2007.

Ojo de Agua Drilling Program

Andina presently has two drill rigs actively drilling the Andrea Zone in the Ojo de Agua area located approximately four kilometres northeast of the Dorado area. Results from the previous Ojo de Agua drill program (3 holes - Andina release dated February 20, 2007) included 104 metres grading 0.81 g/t Au while surface trenching completed during the previous field season returned wide intervals of elevated gold assays including 620 metre grading 0.34 g/t Au with 205 metres grading 0.67 g/t Au. It is anticipated that results from the current program will be available in June 2007.

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.

Under the guidelines of National Instrument 43-101 ("NI 43-101") of the Canadian Securities Administrators, the qualified person for the Volcan exploration project is Ralph Gonzalez, a resident of Burnaby, British Columbia, Canada. Mr. Gonzalez is a professional engineer registered with the Association of Professional Engineers of the Province of Manitoba since 1977, and a Professional Geologist registered with the Association of Professional Engineers and Geoscientists in the Province of British Columbia since 1992. Mr. Gonzalez is independent to the Company as defined by NI 43-101.

Reverse circulation ("RC") chips and diamond drill core from Andina's Volcan drilling campaign are collected at the drill under the direct supervision of Andina staff. Both the RC samples and drill core are 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 are riffle split twice to obtain a 15 kilogram sample for assay purposes. Representative chips are collected from each sample for logging purposes. Drill core is logged, marked at two metre intervals for sampling and split longitudinally with a diamond drill saw. One half of the core is bagged and sample tags attached and the second half of the core is returned to the core boxes. 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 Geoanalitica forward samples to ALS Chemex in La Serena, Chile for 47 trace element analysis using ICP.
