San Marco Announces Completion of I.P. Survey at 1068 Project,

Textbook porphyry geophysical target identified

Vancouver, B.C. – February 27th, 2018: San Marco Resources Inc. (SMN: TSX-V) ("San

Marco" or “the Company”) announces the completion of the previously announced Induced

Polarization survey at the Company’s 100% owned 1068 porphyry copper, gold, molybdenum

project in Sonora State, Mexico.

A pole-dipole IP survey was completed over a 2 kilometre by 2.8 kilometre grid with northeast

trending lines spaced every 400 metres. The survey succeeded, detecting a large chargeability

anomaly measuring 1.2 kilometres by 1.3 kilometres. The anomaly displays high chargeability

readings, peaking at greater than 40 mv/V. The surface projection of the anomaly coincides

with the area already mapped as prospective Laramide aged volcanic units that have been

subjected to pervasive quartz-sericite-clay-pyrite ± iron oxides (phyllic) alteration, characteristic

of the outer shell of a mineralized porphyry system. This mapped leached cap obscures almost

all of the underlying geology, except in a small erosional window where San Marco personnel

were able to map an area of potassically altered rocks. Mineralization which includes early

stage veining contains copper, molybdenum and gold. Potassic alteration is a common feature

of the ore-bearing zones of economically mineralized porphyry systems.

The geophysical modelling shows a large area of high chargeability starting just below the

current surface with the highest values starting 200 metres below surface and extending down

to 400 metres (the limit of the survey). The highest chargeability readings surround a core area

with slightly lower readings. San Marco’s geophysical consultants consider the 1068 target

highly prospective and have recommended a four-hole drill program as an initial test.

Robert Willis, San Marco’s CEO stated; “The IP survey has generated a classic “textbook”

porphyry-style geophysical target. These geophysical results add additional support to our

theory of significant vertical extent below the large surface footprint. Drill hole collars are

expected to be located at or near copper/gold/moly mineralization, which has been locally,

identified right at surface. Each new layer of data that has been generated at 1068 has simply

strengthened the target potential.”

An initial 4 drill holes have been recommended to target across the gradient of higher

chargeability associated with phyllically altered pyritic shell into the lower signature associated

with the potasically altered and mineralized rocks

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.
