San Marco Resources Inc announced 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. CEO Chris T Grijalva said “We are pleased with the results and interpretations of this first phase of work at Espiritu SMR. The important data compilation and invaluable insights from Luciano Bocanegra has confirmed the porphyry copper-moly-gold potential of the Espiritu SMR project and heightened our understanding of its ongoing exploration potential. This extensive interpretive work and recent re-mapping of the project area has better determined the surface extent of the porphyry system(s) and evidenced several of these zones remain open for ongoing exploration. We are now utilizing this new information, interpretations and recommendations as a means of optimizing and streamlining our future work which is expected to include the recommended magnetic and ZTEM surveys to assist in locating a deeper source of the mineralization in advance of possible drilling at the project.”

As part of the Phase I program, San Marco engaged renowned consulting geologist Luciano Bocanegra (see the Company’s news release dated October 18, 2018) 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 system(s)

Confirmation that the best copper mineralization in surface and drill core samples is related to intense quartz-chalcopyrite-pyrite stockwork in potassic altered rocks

Recommendation to conduct additional deeper penetrating geophysical surveying to assist in locating the potential source of the mineralization seen in drill holes
