Targets: Anita Copper Mine, San Bartolo Silver Target, Guayacan North and South Copper-Gold Targets, Cumbral IOCG Trend
The ‘EL COBRE” property targets include the famous Anita Copper Mine, San Bartolo, and North and South Guayacan, examples of near-surface vein-type prospects and the newly-discovered Cumbral IOCG trend.
In some cases going back as far as 1750, these were exploited by the Spanish.
The “EL COBRE” mineralization is characterized by high-grade, gold-copper-silver veins, breccias, and diatremes associated with porphyry deposit-style systems and hematite-magnetite-sericitized zones and structures containing copper-gold-silver mineralization in an IOCG setting.
The 2011 exploration focus was the previously undrilled ANITA COPPER MINE target originally exploited by the Douglas Copper Mining Company (NY) from 1900 until operations ceased in 1910 due to the Mexican Revolution.
A CSAMT resistivity geophysical survey at the Anita Copper Mine target was followed up by 14 shallow diamond drill holes along 250 metres of the estimated 600 metres of outcropping breccia. Oxide copper grades are highlighted by hole ELC 10-05 (nine metres grading 2.37% Cu, 22.72 g/t Ag and 1.17 g/t Au) while down-dip an interval of copper-bearing sulphides partially preserved in quartz breccia graded 5.85% Cu, 127 g/t Ag and 810 ppb Au over one metre.
Future drilling will test unleached, primary, preserved sulphides as interpreted from VTEM airborne geophysical survey results.
The San Bartolo silver target was generated by prospecting and an extensive 3.2 Km x 2 Km detailed soil grid. Sixteen shallow diamond drill holes tested silver-copper-gold soil and rock anomalies identified along several of the trends along approximately 1.5 Km of the strike of the system.
The San Bartolo and Guayacan North and South targets appear to be structurally controlled mineralized zones associated with altered pink granitic bodies.
The newly-discovered Cumbral target, a possible IOCG and/or associated porphyry trend, has been mapped and sampled along 4 Kms of strike and is also associated with pink granites. Pervasive hematite-magnetite-sericite alteration is host to copper-gold-silver breccia and vein styles of mineralization. Recent VTEM and MAG survey results for the Cumbral target identify district-scale alteration and magnetic highs and lows associated with regional faults and intrusive emplacement. Ground magnetic and IP geophysical surveys followed by drilling are planned.
