ANDINA Provides In-Fill Drilling Update on the Volcan Gold Project

TORONTO, ONTARIO--(Marketwire - Feb. 10, 2010) - ANDINA Minerals Inc. (TSX VENTURE:ADM) (the "Company") is pleased to report results to date from the 2009-2010 in-fill drilling programme on the Company's Volcan Gold Project in Chile. As previously reported, the 2009/2010 field season include 20,960 metres of in-fill drilling. Assay results from nine (9) drill holes totalling 3,766 metres on the Dorado West area of the deposit have been received to date, and are reported in Table 1 below. These results continue to highlight the robust nature of the resource and include several areas of better than expected grade that are located within higher grade zones which extend from surface to depth along the vertical axis of mineral deposition.

These new drill results from the Dorado in-fill program provide further confidence to the distribution of the gold mineralization as represented by the updated resource model published in the most recent National Instrument 43-101 compliant resource (see press release dated September 10, 2009). The presence of better than average grade zones (greater than or equal to 1 g/t Au which lie within the broader resource) have been postulated by review of cross sections and level maps. These higher grade zones have not, as yet, been incorporated into an updated model as separate zones. The in-fill drilling has helped test some of the areas of predicted higher grades and the results provide additional confidence to the presence of these better than average grade zones. The potential to segregate zones of higher grade mineralization within the broader volume of lower grade material should offer opportunities to develop alternate exploitation scenarios beyond the simple, base case heap leach scenario that is currently the subject of development studies.

Table 2 compares the average grade across the resource envelope as predicted by the resource block model along each of the recently completed drill hole traces to that of the assayed drill hole composite values (un-cut) over the same envelope. The overall average reconciliation is favourable, with drill hole samples returning, on average, better gold grades than the modeled grades. While this is encouraging, it is not to be viewed as conclusive until the resource model is updated.

"The aim of this in-fill drill program, which began in November 2009, is to confirm the continuity and extent of better than average-grade gold mineralization within the current resource envelope," said George Bee, President & CEO. "Based on these recent positive results, we are gaining a better insight into the gold grade distribution which will allow us to investigate alternatives to the current heap leach concept which may improve gold extraction and project economics at Volcan."

All assays were performed by Laboratorio Geoanalitica, Coquimbo Chile.

Development Study Update

Development planning is progressing well, although the Company has taken the opportunity to expand the scope of the base case Heap Leach alternative to explore strategies to optimize recoveries given the favourable outlook for gold prices. The timing of the Conceptual Design Study ("CDS") and Preliminary Economic Assessment ("PEA") remains targeted for early 2010, and the Company will have a more detailed update on release timing towards the end of February 2010.

Qualified Person

Mr. Michael Easdon is the Qualified Person under National Instrument 43-101 responsible for preparing and reviewing technical information on the Volcan Project in the Dorado and Ojo de Agua areas and ongoing field, sampling and analytical procedures in Chile concerning the aforementioned drill results. Mr. Easdon has reviewed the contents of this press release. Comparisons of the drill results to the block model values were performed by Mr. Reno Pressacco of Micon International Ltd, a qualified person under National Instrument 43-101. The block model in question forms the basis of the Dorado resource update released on September 24th 2009 and available on SEDAR.

Certain technical information regarding the Volcan Project required to be disclosed under Part 3 of National Instrument 43-101 is contained in the Technical Report on the Volcan Gold Project, Region III, Chile and Updated Mineral Resource Estimate for the Dorado Gold Deposits, dated October 23, 2009, prepared by Reno Pressacco, M.Sc. (A), P.Geo., Richard Gowans, P.Eng. and Sam Shoemaker, B.Sc., MAusIMM, each of Micon, and is available on SEDAR at This includes information regarding project area geology, mineralization, rock types and geological controls.

QA/QC Protocols

Andina continues to utilize Canadian Institute of Mining, Metallurgy and Petroleum ("CIMM") prescribed Quality Assurance and Quality Control ("QA/QC") protocols for all sampling and assaying of the core and reverse circulation cuttings. The Dorado drill program utilizes extensive QA/QC protocols for assaying and core sample handling that consist of the systematic insertion of blanks, standards and duplicates as well as using a secondary laboratory for regular check assaying. The core boxes are transported to Copiapo where the core is cut with a diamond saw with one-half of the core being placed in sealed bags, which are then taken to the Geoanalitica preparation facility in Copiapo for crushing and from which the crushed sample is shipped by Geoanalitica to the Geoanalitica assay facility in Coquimbo.

Geoanalitica analyses the samples for gold, copper and molybdenum. The gold assays are performed utilizing 30g fire assay with an atomic absorption spectroscopy ("AAS") or gravimetric finish; the Cu and Mo are assayed for using standard wet analytical techniques.
