Andean American Mining Announces Disclosure Clarification

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 19, 2007) - Andean American Mining Corp (TSX VENTURE:AAG)(FRANKFURT:AQN) -

As a result of a review by the British Columbia Securities Commission (the "BCSC"), we are issuing the following news release to clarify our disclosure.

1. Failure to file NI 43-101 compliant technical report

1. The BCSC has reviewed the Company's technical report on the Invicta Property filed October 31, 2006 (the "Invicta Report") and found it was not completed, in some cases, in accordance with NI 43-101. The non-compliance areas in the report include the following:

a) The report contains a disclaimer of responsibility for the input data and relies on Andean's in-house reports

b) The report contains a historical Invicta resource estimate by Pangea, with significantly higher grades than the October 2006 report estimate. This historical estimate does not comply with s2.4 of NI 43-101.

c) The October 2006 report did not provide adequate discussion of the parameters, assumptions and methodology used for new resource estimates. For example

- It used different cutoffs for estimating measured vs. indicated & inferred resources without adequate explanation.

- It did not support parameters used to estimate gold equivalent grades based on complex gold-silver-copper-lead-zinc mineralogy, including mixed (oxide plus sulfide) mineralization types. The previous gold equivalent grade reporting should not be relied on, and the revised estimates expressed as g/t gold, g/t silver, and % copper follow.

- It did not sufficiently disclose methodology used to estimate inferred resources. The company retracts the prior estimate of inferred resources and its revised inferred resource estimate follows.

d) The October 2006 report presented a 14 million tonne estimate of exploration potential without giving ranges of grades and tonnes, without required cautionary language and without disclosing how the estimate was derived. The company advises that the estimate should not be relied on, and retracts estimates of potential exploration targets for Invicta.

As a result, the author has modified the report in order to address the issues raised and to satisfy NI 43-101 reporting requirements. The author has restated the current Invicta resource estimate and deleted its estimates of exploration potential. The Company is filing an amended Invicta report on SEDAR with an effective date of July 24, 2007.

The revised report includes the following mineral resources:

2. Non compliant disclosure of preliminary assessment

In its news releases of April 5, 2007 and July 4, 2007, the company disclosed economic analysis at Invicta including work by three arms length engineering firms. This included annual production schedules expressed over the mine life as tonnes and equivalent grade per annum, ounces of saleable gold and gold equivalent, after tax profits, internal rates of return, net present value, pay back period, mine life, year of startup, design milestones achieved, and other parameters. The information appeared in news releases, on the Company's website and in investor materials.

The economic analysis should not have been relied on, in part because the company did not disclose that it included inferred resources that are considered too speculative to have economic considerations applied that would categorize them as mineral reserves, and there is no certainty that the analysis will be realized. The company did not disclose the basis of the economic analysis such as the grades, size and classes of the input mineral resource, assumptions made on recoverability of precious and base metals, the names of the qualified persons who conducted the analysis or the other qualifications and assumptions they made.

Andean hereby retracts this information in its entirety. A preliminary assessment has commenced that will address these issues.

3. Erroneous disclosure of a new resource estimate

In its news release of June 14, 2007, Andean erroneously reported Measured and Indicated Resources totaling 4.8 million tonnes grading 3.58 g/t Gold, 33.46 g/t Silver and 0.68% Copper. The statement should have read: Measured and Indicated Resources totaling 4.8 million tonnes grading 2.73 g/t Gold, 18.36 g/t Silver and 0.45% Copper. This error occurred when the historical, non NI 43-101 compliant resource grades determined by previous operator Pangea were mistakenly inserted instead of the October 24, 2006 NI 43-101 technical resource estimate.

4. Non compliant disclosure of potential exploration targets

The company disclosed a 14 million tonne estimate of potential exploration targets at Invicta in news releases, on its website, and in investor materials. The tonnage appeared in the October 2006 technical report without giving ranges of grades and tonnes, without required cautionary language and without disclosing how the estimate was derived. The Company retracts estimates of potential exploration targets at Invicta. The amended July 2007 technical report does not support any estimates of potential.

The company also disclosed and subsequently clarified a 28 million tonne estimate of potential for Invicta, and in its July 4, 2007 clarification news release, attributed this to the Company's October 2006 report. The October 2006 report contained no such estimate and, as indicated above, the company formally retracts estimates of potential exploration targets for Invicta.

5. Adding inferred resources to other categories

In its news releases of November 17, 2006, December 5, 2006, January 8, 2007, January 9, 2007, March 5, 2007 and July 4, 2007, Andean erroneously combined inferred resources with measured and indicated resources. N1 43-101 prohibits adding inferred mineral resources to any other resource categories and Andean therefore retracts this disclosure. This error was also included in website materials, including a fact sheet, a video and a 3rd party article. These materials have been removed from the website. Inferred resources have a great amount of uncertainty as to their existence and economic feasibility. It cannot be assumed that any part of an inferred mineral resource will ever be upgraded to a higher category. Investors are cautioned not to assume that part or all of an inferred resource exists or is economically mineable. Andean retracts this non compliant disclosure of resources information in its entirety.

6. Reporting gross in-situ metal values

In materials on its website and otherwise Andean improperly reported gross in-situ metal values on a deposit scale or per-tonne basis and did not take into consideration operating and capital costs, recoveries, smelter costs and other factors relating to the potential mining, extraction and recovery of metals. The disclosure of gross value for expected mill feed and material "in process" is misleading when given out of context. This disclosure is hereby retracted and has been removed from Andean's website and other materials.

7. Failure to name the Qualified Person

In its news release of December 15, 2006, Andean did not designate the Qualified Person responsible for the scientific and technical information in that release. The news release pertains to an announcement of a new metallurgical flowsheet with significantly improved recoveries, which is material to the future success of the Santa Rosa operation. The company relied on the authority of Juan Zegarra Wuest, MSc, DIC Eng., who has a Master of Science (MSc) in Mineral Processing, Royal School of Mines, London University, England and a Diploma of the Imperial College (DIC) in Mining and Metallurgical Technology, London University, England, as well as engineering degrees from the National University of Engineering, Lima, Peru. The press release had been prepared under the supervision of Mr. Zegarra Wuest. Mr. Zegarra Wuest verified the data disclosed by the release including analytical and test data underlying the information. Mr. Wuest is not a qualified person as defined by NI 43-101 and the information was not prepared by or under the supervision of a qualified person. The company is in the process of applying for a one-time exemptive order regarding Mr. Zegarra Wuest's professional qualifications. In future written disclosure the Company intends to name the qualified person who prepares or supervises all technical and scientific disclosure as required by NI 43-101.

Mr. Andrew Gourlay, P. Geol., President of Sinchao Metals Corp. is a Qualified Person as defined in the Canadian Securities Administrators National Instrument 43-101 with the ability and authority to verify the authenticity and validity of technical and scientific data. This press release has been prepared under Mr. Gourlay's supervision. Andean American Mining holds 67% of Sinchao Metals Corp. Mr. Gourlay is also a member of the Andean American Mining advisory board.

On behalf of Andean American Mining Corp.,

John Huguet, Chairman & CEO
