September 15, 2011, Calgary, Alberta: Antioquia Gold Inc. ("Antioquia" or "the Company") (TSX-V: AGD; OTCQX: AGDXF) is pleased to announce that the Company has extended the high-grade gold mineralization at the Papi Vein Structure at its Cisneros Project, Colombia. Drill hole PAP11-007 intersected 22.25 g/t Au over 3.1 metres, including 34.31 g/t Au over 2.0m and also including 135.6 g/t Au over 0.5 metres.
This summer two (2) additional drill holes (PAP11-006 and PAP11-007, amounting to 442.3 m drilling) were drilled to test the up plunge extension of mineralization previously encountered in drill holes PAP11-001 through PAP11-005. The Papi Vein Structure is a north-east striking, steeply dipping vein structure that has now been confirmed over a strike length of 200 metres and remains open along strike and to depth. Refer to Figure 1 for location.
Table 1 illustrates the results of the two (2) new drill holes and also lists Papi Vein results previously released for comparison purposes.
Table 1. Highlights of 2011 Sampling Results for The Papi Vein Structure
* indicates results from earlier drilling on Papi Vein and results released in Press Release May 27, 2011.
**intervals reported are drilled thickness and may not represent true width.
The Papi Vein Structure was discovered during the 2011 drilling program, and is in addition to the new discoveries at the Chamuela and Soroma structures (refer to Figure 1) reported in the press release of September 12, 2011. The north-east strike of 030° for the Papi Vein Structure is consistent with other vein structures currently being delineated by drilling on the Cisneros Project and Antioquia Gold is optimistic continued drilling on the Papi Vein Structure will not only enhance the discovery, but also uncover additional en-echelon vein structures.
About Antioquia Gold Inc.
Antioquia has been exploring for precious metals in Colombia since 2007. The Company has a land package of close to 40,000 hectares located throughout Colombia. Antioquia's principal asset, which is being actively explored, is its 5,630 hectare Cisneros Project, located 55 kilometers northeast of Medellin in the Department of Antioquia, Colombia. At the Cisneros Project the Company has conducted extensive geochemical and geophysical programs over the entire property and has identified to date six exploration targets. On the original discovery zone it has drilled over 29,000 meters and is well versed in the understanding of the deposit type and the project's path to resource definition and production.
To ensure reliable sample results Antioquia has a rigorous QA/QC program in place that monitors the chain of custody of the samples and includes the insertion of blanks, preparation duplicates, field duplicates, and certified reference standards in each batch of samples. Core is photographed and sawed in half with one half retained in a secured facility for future reference if needed. Sample preparation (crushing and pulverizing) is performed at either SGS or ACME laboratories in Medellin, Colombia.
Samples prepared by SGS (Medellin) are direct-shipped to SGS Laboratories in Lima, Peru or Toronto Canada, both ISO certified laboratories, for analysis. Samples prepared by ACME (Medellin) are direct shipped to ACME Laboratories in Vancouver Canada, also an ISO certified laboratory for analysis. Assay for gold is performed by fire assay with 30g charge and AAS finish, with a gravimetric finish for over limit samples.
This press release has been prepared under the supervision of Brad Van Den Bussche, P. Geol., Vice President of Exploration for Antioquia Gold Inc. and a Qualified Person as defined by National Instrument 43-101.
