2018

• Approximately 1640 meters of core distributed over 7 drill holes.
• 5 holes tested 1.2 km of strike in the NW – SE mineralized corridor and 2 holes tested approximately 400m as a step-out, along one NE – SW section which is perpendicular to the corridor.
• Receptive rock units from surface had been confirmed.
• The main host rock units are andesitic volcanic breccias as well as porphyritic andesites.
• All drill holes reported several intervals with visible copper sulphide mineralization, present as fine grained disseminations and cavity fillings of bornite, chalcocite and trace chalcopyrite. Minor copper oxides occur as fracture fillings.
• Mineralization tends to be erratic in these types of geological systems and is expected to be so in drill core samples.
• Assay results of all drill holes will be reported once they are received and analyzed by the Company.

San Marco CEO Christian Grijalva stated: “We are pleased to have completed Phase I drilling at Chunibas in a completely safe manner and somewhat under budget. Drilling has confirmed that the Chunibas geological model is typical of that of copper-silver “Manto-Type” systems known to exist in northern Chile.”

An initial 1,500 metres over 6 holes is scheduled with the possibility that additional drilling may be conducted, based on initial results.

San Marco CEO Christian Grijalva stated: “We’re very pleased to announce the start of a maiden drilling program at our Chunibas property. Chunibas represents a typical volcanic-hosted copper-silver stratiform system which was previously unexplored. This kind of mineralization was also previously unknown to Mexico and represents a very unique exploration endeavour. The drilling campaign will target higher-grade areas to confirm down-dip and strike extensions.”

Highlights include:

• The Chunibas targets are several copper-silver bearing mantos hosted in volcanic rocks. Copper rich sulphides such as bornite, chalcocite, covellite and idaite predominate, and are locally replaced by copper oxides.
• Recent surface work included 38 rock chip samples, of which 26% assayed greater than 1% copper and 50% greater than 0.2% copper (see news release dated January 16, 2018).
• The manto type mineralization occurs along a “mineralized corridor of approximately 1.7 kilometres of strike and at least 300 metres of width.*
• Previous rock sampling has included grades up to 6.41% copper and 65.6 g/t silver (see news releases dated January 10 and January 16, 2018).
• The Project has excellent infrastructure and access.
• Surface access rights secured.

Mineralization is comprised of copper oxides and primary copper sulphides such as bornite, chalcocite, digenite, covellite and idaite. Mineralization is partially oxidized at surface, though still with significant sulphide content, and is expected to transition into sulphide-only mineralization down dip. All holes will be distributed along strike, angled at -70 and -75 degrees and will test 6 targets over 1.4 kilometres of the 1.7 kilometre known strike extension. Recent exploration results have indicated the mineralized corridor might include additional mineralized mantos.

Chris T. Grijalva, CEO stated, “Preliminary property assessment has allowed us to recognize the porphyry gold-copper-moly potential for Espiritu SMR, the magnitude of which is unknown. The area will be re-mapped to determine the surface extent of the system(s). Our first pass review suggests the mineralized zones are open in all directions. We still need to understand the zoning and other possible controls of the mineralization in order to best target future drilling. San Marco is taking the Espiritu potential very seriously and, for this reason, has engaged an experienced, high calibre expert who immediately will create and execute an aggressive and systematic exploration program. We are targeting late November for completion of this first-pass program.”

Espiritu SMR is located approximately 230 kilometres (“km”) east of Hermosillo and 15 km east of the town of Sahuaripa. Espiritu SMR (acquired through the recent Mexican Government mineral concession lottery), covers approximately 2,712 hectares and is located less than 30 km southeast of the Company´s Chunibas and 1068 Projects. The property hosts porphyry gold-copper and polymetallic silver-lead-zinc mineralization. The gold-copper-moly porphyry system is located over the eastern section of the property, covering an area of 1200 x 1800 metres underlain by a zoned alteration sequence and quartz vein stockwork marked by strong quartz-sericite overprinting earlier potassic alteration.

Historical drill hole assay data* has indications of widespread gold and copper mineralization. Selected historical 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.*The foregoing geological information on the Espiritu property was previously publicly disclosed by (and San Marco obtained it from) Kootenay Silver Inc. (www.kootenaysilver.com) and has not been verified by the Company. Readers are cautioned not to place undue weight on such information. Details of the sampling methods, handling and quality control methods used in the generation of the foregoing historical technical data by Kootenay Silver are unknown to San Marco, and the drill material, assay results, true width of intercepts herein cannot be and have not been verified by the Company’s Qualified Person for the purposes of National Instrument 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators.

For further detail historical information please see Company´s news release dated May 15, 2018.

Early indications suggest the porphyry-related alteration and mineralization footprint is widespread with large scale potential. Detailed mapping should give a more accurate indication of the lateral and depth extensions of porphyry driven mineralization. San Marco has noted that mineralized and altered zones remain partially untested and will be subject of systematic exploration works to be conducted during the upcoming winter season and through the spring of 2019.

Preliminary indications from an historical data review and field validation by Luciano Bocanegra, suggest the past drill hole collar locations, azimuths and depth of the completed ten-hole historical program were, essentially random in relation to the geometry and zoning of the Espiritu SMR porphyry gold-copper-moly system (s). The Company recognizes that a much larger scale potential exists; hence exploration will concentrate on defining and targeting mineralized zones.

Under the Agreement, Antofagasta can acquire a 70% interest in the Project (the “Earn-In Option”) by expending or incurring US $8 million in exploration expenditures in respect of the Project (the “Earn-In Expenditures”) and making cash payments for an aggregate amount of US$ 200,000 over a period of 4 years. Of the Earn-In Expenditures, a firm exploration expenditure commitment of US$700,000 will be used primarily for an initial drill program. Included in that US$ 700,000 will be the reimbursement to San Marco of US$ 100,000 to cover its costs of recent Project exploration expenditures. The initial drill program is anticipated to start as soon as the rainy season ends, and local road conditions improve. San Marco will be the Project operator, under the direction of a Technical Committee consisting of an equal number of members from each company.

San Marco´s CEO Chris Grijalva stated; “We are pleased to have Antofagasta as a partner and look forward to a successful, team approached exploration program on our copper/silver discovery at the Chunibas project. The Project consists of stratiform, volcanic hosted copper-silver mineralization, similar to several ore deposits in northern Chile and is a style of mineralisation not previously discovered in Mexico.

Upon exercise of the Earn-In Option, San Marco and Antofagasta will participate in a joint venture in proportion to their respective interests (30:70) in the Project. If either party’s interest is diluted to 10% or less, the diluting party’s interest will convert into a net smelter return royalty (NSR), ranging from 1% to 2% depending on the circumstances of the dilution.

About The Chunibas Property

The Chunibas property is located approximately 160 kilometres east of Hermosillo, Sonora State; Mexico. The property is comprised of several mining concessions with an overall surface area of 530 hectares.

Chunibas is a stratiform, volcanic hosted copper and silver system represented by mineralized andesitic rocks. Bornite and chalcocite are the main copper minerals that are associated with a primary alteration assemblage of epidote, chlorite, albite and >quartz>calcite>specularite. The mineralized rocks have been recognized over an area of 1700 by 300 metres, and remain open along strike and down dip. Highest assay results include a 6.41% copper and a 27.3 g/ton silver sample.

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 subjected 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.
• 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

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 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.

Forward Looking Information

The property covers 1,115 hectares and is located 62 kilometres (“km”) southeast of the world class Buenavista copper mine (formerly named Cananea) and 42 km to the north-west of La Caridad mine (both operated by Southern Copper Corporation, www.southerncoppercorp.com), in the prolific Cananea-La Caridad copper belt of Northern Sonora State, which is known for being host for world-class porphyry copper deposits, and many high quality exploration copper-moly prospects.

The Suanse property is sandwiched between two mineral concessions within the Llano del Nogal porphyry copper moly property, controlled by Evrim Resources Corp. For related images, visit the Suanse Project on Company’s website.

The Llano del Nogal property hosts Laramide equivalent intrusives with alteration varying from propylitic to locally potassic and quartz-sericite. The primary copper mineralization is chalcopyrite associated to chlorite-K feldspar pyrite and magnetite veins. Interpretation suggests the presence of a shallowly buried porphyry target. *

The Batamote porphyry copper property controlled by Millrock Resources Inc., located 12 km to the east of Suanse, hosts a main alteration zone extending 6 km by 3 km. Millrock has outlined several copper-moly exploration targets, including hydrothermal breccia bodies, porphyry copper sheeted and stockwork mineralization.*

Christian Grijalva, San Marco’s Vice President stated, “We are fortunate to have been awarded a mineral concession covering part of what we believe is a district scale, highly prospective mineral endowed region. Preparations are being made to initiate an exploration program to evaluate the potential of Suanse.”

According to Mexican governmental geological data, the Suanse property overlies a section of a large oxidation and argillization cell, which has an elongated shape trending northeast-southwest and measuring over 8 km along its axis. Associated to this alteration cell are many polymetallic and precious metals prospects hosted by Upper Cretaceous dacitic to andesitic rocks, which in turn are being affected by porphyritic intrusive bodies. Relevant mineral “showings” located within the large alteration cell are Suanse Norte and Suanse Sur prospects which the Mexican geological survey describes as being part of a group of high angle epithermal to shallow mesothermal (Au, Ag, Pb, Zn and Cu) vein systems.

Upcoming Exploration

San Marco geological staff is preparing to do a first-pass ground validation and prospecting work at Suanse. The aim is to assess the alteration cell and look for mineralization within the main Laramide age rock domain and its peripheries, where Late Tertiary (post-mineral) rocks might be obscuring part of any potential mineralized system.
