San Marco acquires Espiritu SMR polymetallic property: Increases district scale exploration footprint in the Sahuaripa District of Eastern Sonora State
San Marco acquires Espiritu SMR polymetallic property:
Increases district scale exploration footprint in the
Sahuaripa District of Eastern Sonora State
Vancouver, B.C. – May 15th, 2018: San Marco Resources Inc. (SMN: TSX-V) ("San Marco" or
“the Company”) is pleased to announce it has been awarded the Espiritu SMR property in the
Mexican government’s recent mineral concession lottery.
Espiritu SMR is located approximately 230 kilometres (“km”) east of Hermosillo and 15 km east
of the town of Sahuaripa. This new land acquisition covers approximately 2,712 hectares and is
located less than 30 km SE of the Company´s Chunibas and 1068 Projects, increasing San
Marco´s exploration footprint at a district scale.
The property is located along a northwest structural trend where less than 100 km to the south
hosts the La India and Mulatos gold mines, which are being operated by Agnico Eagle and
Alamos Gold respectively.
Based on available data from the Mexican geological survey (“SGM”), Espiritu SMR overlies a
window of pre-mineral cretaceous volcanic and sedimentary rocks intruded by Laramide age
granitoids. According to the SGM data, Espiritu SMR covers portions of the San Felipe
mineralized zone, a group of epithermal to mesothermal (gold, silver and lead) vein systems.
Christian Grijalva, San Marco’s Vice President stated, “We believe the Espiritu SMR property is
highly prospective ground demonstrating significant upside exploration potential. The geological
endowment warrants further exploration efforts with “modern day” vectoring and targeting tools.
Preparations are being made to initiate an exploration program to evaluate the overall potential
of Espiritu SMR which is the host for both porphyry gold -copper-moly and silver-lead-zinc
replacement mineralization.”
Previous Exploration
The ground underlying Espiritu SMR´s property has been subject ed to several exploration
campaigns by other exploration companies. The most recent exploration work was conducted
by Kootenay Gold Inc., and various third-party partners via option agreements. According to the
information disseminated by Kootenay Gold Inc., the property has the following characteristics*:
• An extensive area of polymetallic vein, stockwork, breccia and gold -copper porphyry
mineralization.
• Mineralization and alteration are hosted along a 5 km east northeast trending structural
corridor that measures between one and two km in width.
2
• Two zones of mineralization have been recognized; the northeast zone dominated by a
porphyry setting is separated by a major fault from the southwest zone dominated by
veins and stockworks of precious and base metal mineralization.
• Fifty-eight grab samples from the polymetallic southwest zone reported significant
assays from veins that averaged 226 g/ton silver, 1.58% lead and 1.57% zinc with
associated gold and copper values of 0.18 g/ton and 0.15% respectively.
Historical Drilling Results
On May 7, 2010, Kootenay Gold Inc. and its partner , Klondike Silver Corp., reported the
completion of 10 diamond drill holes totalling 2,135 metres. Drilling was designed to test
mineralization within a copper-gold porphyry system over the northeastern zone, covering an
area of 1200 x 1800 metres underlain by a zoned alteration sequence and stockwork marked by
intense secondary leaching. As a result, secondary copper mineralization was encountered
within the stockwork and leached zone, which also reported interesting gold and silver values
along significant long intercepts.*
Selected drill results include:
• Drill Hole ESP-02-09: 48.00 m @ 0.19 g/ton Au; 0.10% Cu; 2.0 g/ton Ag. Including
1.50 m @ 1.80 g/ton Au; 0.07% Cu; 2.0 g/ton Ag
• Drill Hole ESP-06-10: 220.50 m @ 0.14 g/ton Au; 0.15% Cu; 1.1 g/ton Ag.
Kootenay Silver Inc. and its partner Pinecrest Resources Ltd conducted the latest exploration
works at the former Espiritu property. In June 15, 2012, Kootenay Silver Inc. announced the
completion of five-diamond drill holes totalling 409 metres in two of seven known silver-rich
mineralized areas from the southwest zone of Espiritu property.
Selected drill results include:
• Drill Hole ESP-12-01: 41.00 m @ 9.0 g/ton Ag; 537 ppm Pb; 1268 ppm Zn; Including
11.0 m @ 26.2 g/ton Ag; 1388 ppm Pb; 2762 ppm Zn. EOH: 99.0 m
• Drill Hole ESP-12-04: 8.5m @ 12.4 g/ton Ag; 420ppm Cu; 582ppm Pb; 730ppm Zn.
37.5m @ 569ppm Cu; 65 ppm Mo. Including 1.0 m @ 38.0 g/ton Ag; 670ppm Cu;
960ppm Pb; 1580ppm Zn. EOH: 82.0m

Upcoming Exploration
San Marco geological staff is preparing to do a first -pass ground validation and prospecting
work at Espiritu SMR. The aim is to assess the mineralized zones of the main Laramide age
intrusive rocks, which include the Espiritu porphyry copper-moly (±gold) prospect. Exploration
efforts will also dedicated to the polymetallic mineralized system of the southwest zone of
Espiritu SMR, where evidences for high temperature carbonate replacement mineralization has
been documented by past explorers.

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
4
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.
