ANDINA Minerals Inc.: Volcan Drilling Outlines Extensions to Dorado West and East Deposits

New Zones of Gold Mineralization Outlined

TORONTO, ONTARIO--(CCNMatthews - March 26, 2007) - ANDINA Minerals Inc. (TSX VENTURE:ADM) ("Andina") is pleased to report further drilling results from the ongoing US$10 million exploration campaign on its Volcan Gold Project located in Region III, Chile. The results include both infill and extensional drilling in the East Zone, Central Zone, and West Zone gold deposits as well exploration drilling in the NW Zone. A summary of the significant drill assay results are summarized in Table 1 (below). A more complete summary (Table 2) and a drilling plan of the Dorado West Zone Area are attached. To date, Andina has completed approximately 27,000 metres of drilling from the planned 40,000 metre Phase III program.

- West Zone deposit extended 250 metres to the northeast to Section 1375, remaining open to the northeast below the steam-heated alteration zone, to the southwest and to depth along the entire strike. Results include 232 metres grading 0.60 grams per tonne gold ("g/t Au") from hole ROA-633.

- Drilling extends the West Zone deposit mineralization from surface to depths in excess of 300 metres with improving grades: DOA-646 cut 152 metres grading 1.60 g/t Au.

- NW Zone further defined with 102 metres grading 0.67 g/t Au including 28 m grading 1.07 g./t Au and 118 metres grading 0.77 g/t Au including 62 m grading 1.14 g/t Au.

- Dorado East Zone deposit extended 100 metres to the east (REA-657 - 178 metres grading 0.59 g/t Au) and remains open to the east.

"Drilling in the Volcan Gold Project's Dorado area continues not only to expand the dimensions of the three main deposits but also to outline new zones of gold mineralization", commented Carl B. Hansen, President and CEO of Andina. "The extension of the East Zone deposit 100 metres to the east of the existing resource estimate was an positive surprise as is was thought that the Zone was narrowing in this area. Drilling also extended the West Zone deposit to the northeast although deeper drilling will likely be necessary to follow the gold mineralization beneath the alteration cap. And north of the West Zone deposit, drilling further outlined the NW Zone with another gold zone, 200 metres to the south, remaining to be defined. At the Central Zone, results suggest a new extension to the gold mineralization wrapping around a late intrusive body and opening the potential for further discoveries. With five drill rigs onsite drilling the Dorado area gold deposits, shareholders can look forward to further results as Andina continues to aggressively explore its Volcan Gold Project."

Dorado West Zone Area

Drilling extended the West Zone Deposit an additional 250 metres to the northeast towards the flat-lying steam-heated alteration zone which caps the Dorado area mineralized system at an elevation of approximately 5,000 metres. The main West Zone Deposit has now been traced over a distance of 1,000 metres and remains open to the northeast, southwest and to depth although the southwest extension is anticipated to be limited.

As is typical of epithermal systems such as Barrick Gold Corp.'s Chilean Pascua Lama deposit, the near surface gold grades appear to be declining as elevation increases towards the steam-heated alteration zone at 5,000 metres. This can be seen in drill hole ROA-633 (elev. 4,930 m) which returned 232 metres grading 0.60 g/t Au and drill hole ROA652 (elev. 4,989 m) which returned 108 metres grading 0.59 g/t Au. A series of drill holes will target the northeast portion of the West Zone deposit at depths of greater 100 metres below the steam-heated alteration zone, where it is anticipated that gold grades may improve.

To the north of the West Zone, two additional zones of mineralization are being outlined: the NW Zone, and a second as yet to be named zone defined by drill hole ROA-624 which returned 174 metres grading 0.68 g/t. The NW Zone appears to extend over a strike length in excess of 400 metres and is open to the west, to the east under the steam-heated alteration zone, and at depth. Drilling results included 102 metres grading 0.67 g/t Au including 28 metres grading 1.07 g/t Au and 118 metres grading 0.77 g/t Au including 62 m grading 1.14 g/t Au. Further drilling is necessary to define both gold zones.

Dorado East Zone Deposit

Of the three drill holes collared into the East Zone Deposit, REA-657, a 100 metres step-out hole to the east of the existing resource estimate returned 178 metres grading 0.59 g/t Au including a 78 metre interval grading 0.86 g/t Au and 28 metres grading 1.30 g/t Au. Until this hole, it was thought that the East Zone was pinching to the east, however, the results from REA-657 suggests that the potential to further extend the gold zone to the east is good.

Drill hole REA-639, which was collared to test the westerly extension of the East Zone deposit was unfortunately lost prior to intersecting the target depth. Drill hole REA-642 confirmed the southern boundary of the East Zone along section V-3.

Dorado Central Zone Deposit

Drill hole RCA-650 was an infill hole testing the core of the Central Zone. The hole returned a better than anticipated 172 metres grading 0.90 g/t Au starting from surface further defining the core of the deposit.

Drill hole ROA-643 successfully tested the theory that the Central Zone gold mineralization may wrap around the contact of a late intrusive unit as defined by ground magnetics. The hole returned 82 metres grading 0.51 g/t Au opening the possibility that the gold mineralization may continue to extend around the intrusive body.

Drill holes RCA-658 and RCA-659, were both significant step-out exploration holes drilled along the east boundary of the West Zone deposit. RCA-658, drilled closer to the West Zone, cut 50 metres grading 0.43 g/t Au. RCA-659 returned no significant results.

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.

The reverse circulation ("RC") chips and diamond drill core from Andina's drill 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. Both the RC samples and drill core 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. Drill core was logged, marked at two metre intervals for sampling and split longitudinally with a diamond drill saw. One half of the core was bagged and sample tags attached and the second half of the core was 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.
