San Marco Resources Inc. announced that it has completed a critical first phase of exploration and evaluation which confirms the existence of a porphyry copper-molybdenum-gold system at its 100% owned Espiritu SMR property in Sonora State, Mexico. In addition, work from this phase has identified previously unrecognized vectoring tools to optimize future exploration efforts toward priority target areas of potential best-grade mineralization. As part of the Phase I program, San Marco engaged renowned consulting geologist Luciano Bocanegra to lead the San Marco team in the reinterpretation and consolidation of all previous data from the Espiritu SMR property. Data utilized in this evaluation included geological mapping, surface rock sampling, re-logging of historical drill core and review of rock geochemical data. Results and recommendations from Mr. Bocanegra's work included confirmation of a multi-stage copper-moly-gold porphyry system with a minimum alteration footprint measuring 2.5 km x 1.2 km, open in multiple directions; Identification of previously unrecognized vectoring tools that can assist in targeting potential areas of best-grade mineralization to depth and buried targets under post mineral rocks; Indication that copper mineralization may be preserved at depth within the shallower part of the porphyry systems; Confirmation that the best copper mineralization in surface and drill core samples is related to intense quartz-chalcopyrite-pyrite stockwork in potassic altered rocks; and Recommendation to conduct additional deeper penetrating geophysical surveying to assist in locating the potential source of the mineralization seen in drill holes.
