Eco Oro infill drilling returns high grade results at Angostura
VANCOUVER, Feb. 6, 2013 /CNW/ - Eco Oro Minerals Corp. ("Eco Oro" or the "Company") (TSX: EOM) reports that results from the infill drilling program completed to September 2012 continue to outline higher grade gold mineralization favourable to underground mining at its multi-million ounce Angostura gold-silver deposit in northeastern Colombia. Results from this drill program will be used for an updated resource, which is estimated to be completed in Q1 2013.
Fifty six additional infill drill holes over 22,983 m have been completed since the last news release on drill results dated November 30, 2011. Highlights from this drilling include:
- 59.7 g/t Au and 30.7 g/t Ag over 4.8 m in hole SI12-06
- 26.5 g/t Au and 18.2 g/t Ag over 2.6 m in hole QP011-01
- 16.9 g/t Au and 0.6 g/t Ag over 3 m in hole DM12-08
- 14.2 g/t Au and 3.0 g/t Ag over 2 m in hole GTC-06
- 7.4 g/t Au and 11.3 g/t Ag over 6 m in hole DM11-30
In 2012 the infill drilling was concentrated in the western limit of the Angostura deposit going from the Diamante area through to the Silencio area, with one hole each drilled in Veta de Barro and La Alta. A representative sample of the 291 intercepts containing >2 g/t Au is illustrated in the following table:

A complete list of results as well as a map showing the location of the 56 holes drilled is available on the Company's website at www.eco-oro.com/Projects/Angostura.
Results confirm higher gold grades in the infill areas than was encountered from the wider spaced drilling previously completed. Of this drilling, geotechnical and hydro geological drilling programs totaled 3,231 m in 18 holes, of which 2,714 m in eight holes were used in both geotechnical and infill programs.
"Results from the infill drilling program reinforce management's expectation that the deposit has the continuity of mineralized zones and high grades required for underground mining, as well as demonstrating further upside potential at depth. Results from the geotechnical and hydro geological drilling will provide valuable information, which will ensure that Eco Oro effectively addresses any associated safety and environmental concerns of the surrounding community." states Joao Carrelo, President and CEO of Eco Oro.
The 2011/12 drilling program provides a better geometric definition of the mineralized structures, required for planning of the underground mine design, and has contributed to a more robust resource model for underground development of the Angostura deposit.
The latest results further enhance the information of the very high grade mineralization, with 15 additional individual intercepts with grades exceeding 20 g/t Au, for a total of 454 individual intercepts in the entire Angostura drill database having a weighted average grade of 37.8 g/t Au. Drill programs focused on identifying high grade mineralization have consistently confirmed good vertical continuity containing high grades.
Results from the 2011/12 drilling program indicate that targeted higher grade gold shoots have an average intercept length of 7.44 m with an average weighted gold grade of 6.35 g/t Au and an average weighted silver grade of 18.22 g/t Ag. The table below shows statistical results of all infill drilling completed since that reported in November 2011:

Quality Control and Reports
The Company employs a quality control program to ensure sampling and analysis of all exploration work is conducted in accordance with the best possible practices. Under these quality assurance measures, drill core is sawn into halves with one half of the core prepped on site and samples shipped to ALS-Chemex Laboratory in Vancouver, B.C. for analysis. The remainder of the core is retained for future assay verification. Gold analysis is conducted by fire assay (one assay tonne) using an atomic absorption finish. The laboratory re-assays using the ALS-Chemex protocol, and additional checks may be run on anomalous values. Eco Oro has independent re-analysis and sample preparation checks run at other accredited laboratories. The Company also introduces background blanks prepared from previously analyzed core samples from the Angostura Project.
