San Marco Resources To Begin Phase One Drill Program at Chunibas Project; Appoints New Chief Financial Officer

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 4, 2017) - San Marco Resources Inc. (TSX VENTURE:SMN) ("San Marco" or the "Company") announces it has commenced preparation for Phase One core drill program at its 100% owned Chunibas gold/silver project, located approximately 160 kilometres east of Hermosillo, Sonora State, Mexico.

  • The Chunibas targets are a series of high-grade gold bearing veins hosted in intrusive rocks
  • There are 5 main vein zones; Santa Rosa, Argentina, Santa Fe, Gusima, and Western, which comprise a "mineralized corridor" 750 metres wide and 1.5 kilometres long
  • The Company's sampling of the one to two metre-wide structures has resulted in grades up to 46 g/t gold
  • The Project enjoys excellent infrastructure and access
  • Surface access rights secured
  • Access road repair and drill pad construction is commencing
  • Drilling expected to begin by the end of May
  • Additional drilling maybe scheduled, based on initial results

The primary objectives of this drilling will be to confirm the presence of higher-grade mineralization within the discrete shear veins, as well as the presence of broad haloes of lower grade Au-Ag within adjacent, sericite - Fe carbonate altered wall rocks. Historical data has been incorporated with the Company's recent exploration work, resulting in field evidence that the north-south trending shear/vein structures coalesce in various zones along strike. This has reinforced the geological model that wider zones of gold mineralization, flanking the high-grade shear structures, some of which continue to be mined by local gambosinos (miners), where grades appear to be in the 15 g/t gold range, exist. *

An initial 4 core holes totalling approximately 500 metres is contemplated, two holes in the Santa Fe zone; one hole 400 metres along strike to the north in the Santa Rosa zone; and one hole a further 350 meters to the north in the Argentina zone. These holes are located in areas of old gambosino workings, as well as several historic reverse circulation drill holes. *

In addition, baseline metallurgical test work will also be completed, with the objective of determining precious metals recoveries as a function of degree of oxidation.
