San Marco Discovers High Grade Copper – Silver At Chunibas; Samples up to 5.9% Copper and 66 g/t Silver
San Marco Discovers High Grade Copper – Silver At Chunibas;
Samples up to 5.9% Copper and 66 g/t Silver
Vancouver, B.C. – January 10th, 2018: San Marco Resources Inc. (SMN: TSX-V) ("San
Marco" or “the Company”) announces the first assay results from the newly discovered copper
and silver mineralization at the Company’s 100% owned Chunibas property, located
approximately 160 kilometres east of Hermosillo, Sonora State, Mexico.
As discussed in the Company’s news release dated November 29th, 2017, and as a follow-up to
the Company’s grid soil sampling program, a strong copper/silver soil anomaly was defined in
the northwest sector of the Chunibas project, an area that has seen little exploration by San
Marco or past workers. Copper oxides have now been recognized and sampled from random
outcrop exposures scattered over at least 1.2 kilometre of strike, and at least 100 metres of
width. Additional sampling is ongoing in an effort to determine the full extent of mineralization,
which remains open in all directions. Copper oxides (malachite and minor azurite) appear as the
result of oxidation of chalcocite and bornite. Highlights of the initial 16 samples within the known
zone of mineralization are;
Sample number Cu (%) Ag (g/t)
366502 0.16 1.2
366503 5.90 50.7
366507 0.87 5.9
366508 0.76 8.4
366510 1.38 19.4
366511 0.97 4.0
366513 1.84 17.2
366516 0.41 3.6
366557 3.72 65.6
366572 0.25 3.6
San Marco’s CEO, Bob Willis stated: “This most recent discovery is further evidence of the
regional implications of this very large mineralized system. Our recent drilling at the Santa Fe
target at Chunibas discovered wide intervals of gold mineralization in hydrothermal breccias .
Our newest discovery is primarily copper and silver mineralization in a different geol ogical
environment, over an area, which is open in all directions. While sampling is, by necessity,
confined to outcrop exposures it is important to note that mineralization has been discovered in
most exposures within a large and growing area. Every effor t was made to generate
2
representative rock chip samples of entire individual outcrop exposures. There is no evidence
that this zone was previously explored or sampled. Management considers this new discovery
highly significant and is following up on it aggressively.”
Outcrop exposure in the area containing this new mineralization is generally poor. Sample
points are dictated by irregularly spaced outcrops, represented by knobs, weather resistant
ridges and small sub-crops, located within colluvium and soil covered foothills. At this point it
does not appear that the mineralized outcrops are structurally related or created by preferential
weathering, as copper mineralization has been found in several alteration regimes and rock
types within this broad zone.
Host rocks are presumed to be Laramide age intermediate volcanics, which have variable
textures, andesite breccias; porphyritic andesite and vesicular -amygdaloidal andesites. Copper
and silver mineralization is mainly hosted in the andesite breccia which are moderately to
strongly altered by an assemblage of epidote>chlorite>quartz>calcite>specularite.
Mineralization occurs mainly as disseminations, patches, cavity fillings, minor veinlets and
hydrothermal breccias.
Additional and pending exploration;
• Next batch of assay results of additional outcrop chip samples expected in
approximately one week.
• Results of a Petrographic study to identify specific copper minerals expected in one
week.
• Property exploration has resumed after the Christmas break. In addition to continued
reconnaissance chip sampling, detailed channel sampling of known copper mineralized
outcrops to be initiated.
• Induced Polarization (I.P.) as well as ground magnetic surveys are being considered to
help define the boundaries of the system, as is trenching.

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 implemented, including
such measures as external blanks, standards and duplicate s amples. 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.
