Vancouver, B.C. – November 6, 2018: San Marco Resources Inc. (SMN: TSX-V) (“San Marco” or the “Company”) announces that diamond drilling has commenced at its 100% owned Chunibas copper-silver project, located in Sonora State, Mexico (the “Project”). San Marco and a wholly-owned subsidiary of Antofagasta plc (“Antofagasta”) have entered into an earn-in agreement (the “agreement”) to jointly explore and drill test several copper-silver rich mineralized targets. For further detailed information about the “Agreement”, please see Company´s news release dated August 9th, 2018.

The primary focus of this drilling will be to confirm the down-dip and along strike projections of high-grade copper-silver mineralization, as well as to test for the presence of additional mineralized mantos. The Company’s recent exploration work, confirms the presence of various mineralized zones along strike and at different stratigraphic levels. This has reinforced our manto-type geological model and as a result, the drill program is designed to not only test the potential high-grade mantos, but the possibility of a significant large scale-size opportunity.

An initial 1,500 metres over 6 holes is scheduled with the possibility that additional drilling may be conducted, based on initial results.

San Marco CEO Christian Grijalva stated: “We’re very pleased to announce the start of a maiden drilling program at our Chunibas property. Chunibas represents a typical volcanic-hosted copper-silver stratiform system which was previously unexplored. This kind of mineralization was also previously unknown to Mexico and represents a very unique exploration endeavour. The drilling campaign will target higher-grade areas to confirm down-dip and strike extensions.”

Highlights include:

• The Chunibas targets are several copper-silver bearing mantos hosted in volcanic rocks. Copper rich sulphides such as bornite, chalcocite, covellite and idaite predominate, and are locally replaced by copper oxides.
• Recent surface work included 38 rock chip samples, of which 26% assayed greater than 1% copper and 50% greater than 0.2% copper (see news release dated January 16, 2018).
• The manto type mineralization occurs along a “mineralized corridor of approximately 1.7 kilometres of strike and at least 300 metres of width.*
• Previous rock sampling has included grades up to 6.41% copper and 65.6 g/t silver (see news releases dated January 10 and January 16, 2018).
• The Project has excellent infrastructure and access.
• Surface access rights secured.

Mineralization is comprised of copper oxides and primary copper sulphides such as bornite, chalcocite, digenite, covellite and idaite. Mineralization is partially oxidized at surface, though still with significant sulphide content, and is expected to transition into sulphide-only mineralization down dip. All holes will be distributed along strike, angled at -70 and -75 degrees and will test 6 targets over 1.4 kilometres of the 1.7 kilometre known strike extension. Recent exploration results have indicated the mineralized corridor might include additional mineralized mantos.

National Instrument 43-101 Disclosure

This news release has been approved by San Marco’s Co-Chairman, Robert D. Willis, P. Eng. a “Qualified Person” as defined in National Instrument 43-101, Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators. He has verified the data disclosed, including sampling, analytical and test data, underlying such technical information by reviewing the assay reports provided to San Marco by its independent testing laboratory.

San Marco has implemented quality assurance (“QA”) and quality control (“QC”) programs to ensure sampling and analysis of all exploration work is conducted in accordance with the best possible practices. All sampling programs are carried out in a careful and diligent manner using scientifically established sampling practices designed and tested to ensure that the results are representative and reliable. Quality control programs appropriate to the type of sample and the mineralization are implemented, including such measures as external blanks, standards and duplicate samples. The security of samples from sample acquisition to analysis is a vital component of the sampling process. Procedures include the use of secure core logging, sampling, storage and preparation facilities as appropriate and the prompt, secure and direct shipping of samples to the laboratories. Appropriate sample security procedures are employed given the geographic and topographic conditions and the logistics created by the site location.
