San Marco Continues to Discover High Grade Mineralization at Chunibas;
Samples 6.41 % Copper and 27.3 g/t Silver
Vancouver, B.C. – January 16th, 2018: San Marco Resources Inc. (SMN: TSX-V) ("San
Marco" or “the Company”) announces further assay results from continuing fieldwork at
Chunibas. As disclosed in the Company’s news release dated January 10th, 2018, newly
discovered copper and silver mineralization at the Company’s 100% owned Chunibas property
has been located over an area of approximately 1.2 kilometres of strike and at least 100 metres
of width. That zone has now been extended to 1.7 kilometres of strike and up to 150 metres of
width, and open in all directions.
Recent surface work included 38 rock chip samples, of which 26% assayed greater than 1%
copper and 50% greater than 0.2 % copper. Highlights of the recent 38 assay results are:
Sample number Cu (%) Ag (g/t)
366587 0.75 4.8
366588 1.28 13.7
366589 2.62 26.3
366590 1.29 5.83
366591 1.82 29.8
366592 1.52 10.9
366596 3.95 32.8
366597 6.41 27.3
366601 2.13 7.2
366606 1.59 10.8
366608 0.58 3.6
366610 1.06 5.1
366612 0.87 1.9
An initial petrographic study has identified bornite, chalcocite, covellite and idaite as the primary
copper minerals which appear associated with hydrothermal alteration. Microscopic textural
features indicate that chalcocite, covellite and idaite are replacing bornite. The nature of the
replacement could be a late hydrothermal event or supergene. The dominant alteration
assemblage is represented by Iron – epidote -> chlorite > quartz > calcite.

The andesitic host rocks of presumed Larimide age have undergone hydrothermal alteration,
represented by patches, cavity filling and microbrecciation.
Additional and pending exploration on the Chunibas property includes:
• Continuous rock chip channel sampling over outcrops is underway.
• Follow-up more detailed petrographic studies to be initiated.
• A trenching program between individual outcrops is being evaluated. Success of this
program will depend on the depth of cover between outcrops.
• Induced Polarization (I.P.), as well as ground magnetic surveys are being considered to
help define the boundaries of the system.

National Instrument 43-101 Disclosure
This news release has been approved by San Marco's CEO, 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 implemente d, 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.
