San Marco Commences Exploration on Oregano
San Marco Commences Exploration on Oregano
Vancouver, B.C. – May 24th, 2017: San Marco Resources Inc. (SMN: TSX-V) ("San Marco" or
the “Company”) announces it has commenced exploration on the Oregano project, located
within the Company’s 73,000 hectare Mariana concession (appl.), approximately 240 kilometres
east of Hermosillo, Sonora State, Mexico.
The objective of this exploration program, using saw cut continuous channel samples, will be to
identify anomalous grades of vein mineralization, over greater widths than previously known.
The geological model at Oregano suggests the “boiling zone “, and presumably higher grades of
gold and silver, may be only 150 – 200 metres (“m”) below the veins surface exposure.
San Marco’s CEO, Bob Willis stated; “ We are excited to commence this new phase of
exploration at Oregano and believe a cost-effective, focused program of work has an excellent
chance of encountering higher grade gold mineralization and generating drill targets for further
exploration.” The Oregano mineralized system has been traced for three kilometres and
appears to be open. This is a District scale exploration opportunity for our shareholders.”
The initial phase of exploration will include systematic diamond saw cut channel samples across
the veins and detailed geologi cal mapping of the structures. Five of a proposed 15
channel/trenches have been completed. Of significance, after removing minimal overburden
from flanks of the vein outcrops, true widths of the individual veins appear to be in the 5 – 15 m
range, wider than 2 – 3 m vein widths previously known.
Of a total of 72 sample individual samples (each at least 1 m wide), 25% of the gold assays are
greater than 0.20 g/t (up to 1.1 g/t; and 24% of the silver assays are greater than 10 g/t (up
38.2 g/t).
Assay results from the initial five trenches over 350 m of strike are;
Trench: Z – 01 - anomalous gold/silver
Z – 02 - 23.5 m @ 0.33g/t gold and 9.0 g/t silver including 10.30 m @ 0.52 g/t gold
and 10 g/t silver
Z – 03 - 14.3 m @ 0.31 g/t gold and 5.0 g.t silver
Z – 04 - 31.4 m @ 0.12 g/t gold and 15.0 g/t silver
Z – 05 - 16.6 m @ 0.12 g/t gold and 10.0 g/t silver
The Oregano property is favourably located within the Sierra Madre Occidental belt of
epithermal gold-silver deposits, and hosts a semi-continuous, three kilometre North-South belt
of low sulfidation quartz veins which has only received limited historical exploration.
Vein textures, including well-developed lattice, bladed and cockade features, suggest the
surface exposes of the veins are in the upper levels of the mineralizing system, such that
excellent exploration potential exists along strike and at depth. Quartz varieties include,
chalcedony, opaline, silica replacing calcite, cryptocrystalline, in veins striking north – south and
dipping approximately 73 degrees to the east.

Host rocks include both felsic (rhyolite, rhyodacite) and intermediate (andesite) compositions,
and occupy a favourable stratigraphic setting near the interface between the regionally
correlative Lower and Upper Volcanic Series.

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.
