Andean American Announces a Revised Mineral Resource Estimate on its Invicta Property
(firmenpresse) - TORONTO, ONTARIO -- (Marketwire) -- 04/30/12 -- Andean American Gold Corp. ("Andean American" or the "Company") (TSX VENTURE: AAG)(FRANKFURT: AQN) announces that it has received an updated NI 43-101 Technical Report of the mineral resources at the Invicta Gold Project in Huaura Province in Peru. The report was prepared by SRK Consulting (US) Inc. ("SRK").
The mineral resources for the Invicta gold-silver-copper-lead-zinc deposit are estimated by SRK at 8,644 kt grading an average of 2.13 g/t gold, 15.90 g/t silver, 0.43% copper, 0.24% lead and 0.29% zinc, classified as Measured and Indicated mineral resources; with an additional 2,534 kt grading an average of 1.61 g/t gold, 12.02 g/t silver, 0.46% copper, 0.27% lead and 0.18% zinc, classified as Inferred mineral resources.
(i) Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into a Mineral Reserves estimate. The resource is stated above a 1.30 g/t gold equivalent cut-off and contained within potentially economically mineable mineralized solids. Metal prices assumed for the gold equivalent calculation are US$1,500/oz for gold, US$32.50/oz for silver, US$3.90/lb for copper, US$1.05/lb for lead and US$1.00/lb for zinc. The gold equivalent calculation assumes 100% metallurgical recovery, and does not account for any smelting, transportation or refining charges. Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding. Mineral resource tonnage and grade are reported as diluted to reflect a potentially mineable underground SMU (Selective Mining Unit) of 3.0m. The resource model has not been depleted for historical artisanal mining, as the location and extent of these workings are largely un-documented.
Mineral Resource Sensitivity
In order to assess the sensitivity of the resource to changes in gold equivalent cut-off grade, SRK summarized tonnage and grade above cut-off at a series of increasing gold equivalent cut-offs by resource category. The sensitivity analysis for Measured plus Indicated blocks and Inferred category blocks are provided in Tables 2 and 3, respectively.
SRK has made certain recommendations in terms of further exploration work and trade-off studies. They suggest completing detailed structural-geological mapping over the entire project and the development of a structural and stratigraphic 3D model to identify exploration targets, as well as a regional structural geological interpretation of airborne and remote sensing data. Trade-off studies to determine the most suitable mining method and production rate are recommended, as well as the completion of preliminary project cash flow modeling to estimate project economics. This evaluation is currently in progress for higher grade and lower treatment tonnage options.
Rationale for the Revised Resource Estimate on the Invicta Project
In October 2011, Andean announced that the initial capital cost to build an underground mine at the Invicta Project would be considerably higher than forecast in the July 2010 Feasibility Study, partly due to increases in the estimates for infrastructure. Andean's management and Board of Directors decided to delay completion of the SRK Feasibility Study on the Invicta Project in October 2011, and indicated that the (then ongoing) engineering studies would not be completed to a feasibility level at that stage. The SRK Feasibility Study on the Invicta Project was discontinued at that time.
There is neither a current Pre-Feasibility Study (PFS) nor Feasibility Study (FS) for the Invicta Project, which incorporates all presently applicable Invicta Project cost estimates. It follows that there are no current mineral reserves for the Invicta Project in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum Standards on Mineral Resources and Reserves: Definitions and Guidelines, November 27, 2010 (CIM).
For this reason, in a press release issued on February 13, 2012, Andean announced that it had commissioned SRK to do a revised resource estimate which reclassifies the (previous) Mineral Reserves as Mineral Resources as set out in the table above. There are no current Mineral Reserves estimated for the Invicta Project.
Commenting on the revised resource estimate for Invicta, Mr. David Rae, President and CEO of Andean American, said: "We believe that this new resource estimate for Invicta supports our view that the Invicta Project lends itself to a higher grade lower tonnage mining scenario and we continue to review alternatives which will reduce the capital costs and improve project economics. This revised technical report incorporates the structural geology work completed in late 2011 and has given us some valuable insight into the potential on the property. We are anxious to realize value from the Invicta Project which will benefit both our shareholders and the local communities. Much of the work we would like to do requires the support of the local communities and we continue to seek agreements with them which will ensure benefits for all parties."

Qualified Person
The resource estimate was completed by Frank Daviess, MAusIMM under the direction of Jeffrey Volk, CPG, FAusIMM, Principal Resource Geologist with SRK. Mr. Volk is independent of the issuer and an Independent Qualified Person, as this term is defined in NI 43-101 and has reviewed and approved the scientific and technical disclosure contained in this release. The effective date of this resource estimate is April 6, 2012 and is based on data received by SRK in November, 2010. The mineral resources are reported in accordance with Canadian National Instrument 43-101 (NI 43-101) and have been estimated in conformity with generally accepted Canadian Institute of Mining, Metallurgy and Petroleum (CIM) "Estimation of Mineral Resource and Mineral Reserves Best Practices" Guidelines. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource will be converted into mineral reserves.
