San Marco identifies additional significant Copper/Silver mineralization on Chunibas and begins Drill preparation
San Marco identifies additional significant Copper/Silver mineralization on
Chunibas and begins Drill preparation
Vancouver, B.C. – July 19th, 2018: San Marco Resources Inc. (SMN: TSX-V) (“San Marco” or
the “Company") announces the results and recommendations of its continuing Chunibas
exploration program. Most recent surface exploration activities included geological mapping,
trenching and geochemical surveys. As a result, the San Marco team has expanded the known
surface expression of the mineralized system and confirmed consistent copper mineralization in
several areas within the larger system.
San Marco CEO Christian Grijalva stated: “We’re very pleased with the results we have
generated over the past few months at Chunibas. We’ve been able to conclusively demonstrate
that the copper mineralization on the Chunibas property represents a typical volcanic-hosted
stratiform system, analogous to several known copper-silver Chilean deposits but previously
unknown in Mexico. Now that we have confirmed both scale and consistency, the next step will
be preparations for a drilling campaign to locate higher -grade areas and then expand those
areas down-dip and along strike. The Company expects a drill program could start as soon as
the rainy season ends, and local road conditions improve.”
Exploration Results
Highlights include:
• Recent exploration has identified many new copper/silver occurrences. Ninety-six new
rock chip sample assay results had been received. Approximately 80% of these samples
exhibited visible copper oxide/sulphide mineralization with 41% of these sample assays
having copper values greater than 0.1%. The highest reported copper grade is 1.34%
• Attempts to excavate hand dug trenches were very challenging due to the craggy
undulating rock/alluvium contact. Highlights of the few successful saw -cut continuous
channel samples are: 30 metres (“m”) at 0.16% copper (“Cu”), 2.6 g/t silver (“Ag”) and
22m at 0.17% Cu and 2.3 g/t Ag.
• Portable X-ray fluorescence rock analysis was conducted over an area of 300 m by
1400 m. The results indicate anomalous to significant copper values remain consistent
throughout and along the entire corridor.
• The mineralized NW-SE corridor is 1.7 kilometres by 300 m and remains open along
strike and down dip.
• Copper sulphide mineralization occurs as a non-supergene bornite-chalcocite-(diginite)
assemblage. Copper oxides are also common.

Exploration Plans
Integration of the recent exploration results into the Chunibas database to generate a
comprehensive exploration strategy is ongoing.
The following exploration program will continue until the Company begins its maiden drill
campaign following the end of the current summer rainy season:
• Detailed geological mapping and “in fill” rock chip and channel sampling over the south-
eastern extension of the mineralized corridor.
• Anomalous copper points identified by portable X -ray fluorescence rock analysis, in
combination with known and recently found mineralized occurrences, will be considered
for future drill hole locations.
• Drill targets will be defined to adequately test on-strike, down-dip, and depth projections.

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.
The Company 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.
