ANDINA Minerals Inc.: Volcan Trenching Outlines Significant Gold Mineralization.

TORONTO -- Andrea Zone Sampling Returns 205 Metres Grading 0.67 g/t Gold

ANDINA Minerals Inc. (TSX VENTURE:ADM) ("Andina" or "the Company") is pleased to update the results from the continued channel sampling program from the Ojo de Agua area on its Volcan Gold Project, Chile. To-date, assays from 688 samples have outlined a new zone of anomalous gold mineralization, referred to as the Andrea Zone, measuring approximately 900 by 400 metres. Results include a 205 metre interval which graded 0.67 grams per tonne ("g/t") gold. The Andrea Zone represents only a small portion of the 2 by 2 kilometre Ojo de Agua maar diatreme complex located 3 kilometres north northeast of the Dorado area, the location of Andina's ongoing definition drilling program.

Eight trenches were cut and channel sampled essentially on three levels, spaced 50 to 150 metres apart, along the southeast facing slope of the Andrea Zone. Trench TR-1 (see table 1), located approximately 50 metres vertically below an extensive sub-horizontal blanket of acid leached (steam-heated) alteration, returned a broad zone of elevated gold mineralization: 620 metres grading 0.34 g/t, including 205 metres grading 0.67 g/t with higher grade intervals of 0.97 g/t over 80 metres and 1.34 g/t over 25 metres. Trench TR-1 encompasses the 165 metre trench previously reported by Andina (see January 24, 2006 press release) which returned 165 metres grading 0.45 g/t gold including the 25 metre interval grading 1.34 g/t gold noted above.

"Preliminary results from the Ojo de Agua exploration program have been very encouraging", stated Carl Hansen, President and CEO. "The widespread occurrence of significant gold mineralization at the Andrea Zone suggests the presence of a large underlying mineralized system requiring further exploration.Trenching and channel sampling continue in the area and platforms have been prepared at the Andrea Zone for drilling to commence, weather permitting, prior to the end of April."

Channel samples from three trenches, including TR-11 and TR-12, located 150 metres northwest of trench TR-1 and situated immediately below the acid leached alteration zone, returned elevated gold values with locally significant intervals above 0.5 g/t including 40 metres grading 0.85 g/t and 40 metres grading 0.58 g/t. The presence of gold mineralization at the base of the alteration zone was unexpected as typically gold deposition occurs lower in the system.

Trench TR-8, located 100 metres southeast of and 25 metres vertically below TR-1, returned 70 metres grading 0.46 g/t gold including a 25 metre interval, at one end of the trench, grading 0.73 g/t gold and open to the southwest.

The Andrea Zone gold mineralization appears to be associated with wide zones of narrow veinlets and fractures filled with variable amounts of iron and manganese carbonate, magnetite and quartz cutting dacitic breccias. The orientation of the gold mineralization has not yet been determined.

As expected, samples from 5 additional trenches cut into and above the acid leached alteration zone returned essentially negligible gold values.

About Andina Minerals Inc.

Andina is an Americas focused exploration company with a portfolio of precious metals exploration projects in Chile which is dedicated to maximizing the value of its exploration assets through a commitment to fiscally responsible exploration. The Company is earning a 100% interest in the Volcan project by undertaking certain work commitments and making a series of escalating payments ending in 2008.

Under the guidelines of National Instrument 43-101, the qualified person for the Volcan exploration project is Eduardo Magri, Ph.D. in mining engineering (Witwatersrand) and a Fellow of the SAIMM with over 30 years of industry experience. Mr. Magri has approved the exploration program and established the quality assurance and quality control programs to ensure the accuracy of the collection and analysis of samples.

Samples are processed and analyzed for gold using fire assay techniques with atomic absorption finish. Samples which returned gold values greater than 1.00 gram per tonne 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 ship samples to ALS Chemex in La Serena for 47 trace element analysis using ICP.
