During construction of a preliminary access road to potential drill site areas, mineralization was noted in the roadway with copper values up to 0.76%, gold up to 0.17g/t and molybdenum up to 2050 ppm over 3 – 4 metre channel samples. Drilling is recommended after additional surface mapping and sampling is completed. Preparation for such work will commence immediately.

Exploration Highlights

Highlights of the exploration include;

• Surface alteration and mineralized footprint has increased to 1.6 kilometres X 1.5 kilometres (“km”) and is open for expansion in at least two directions.
• Poorly exposed erosional window into potassically altered mineralized intrusive (100 metres by 200 metres) is an obvious drill target.
• Extensive phyllically altered and stockwork-quartz-veined volcanic lithocap (as above, 1.6 km X 1.5 km and open) may have created favourable conditions for sealing the system acting as a trap for fluids, enhancing the mineralizing process. Drilling through this volcanic cap is another obvious drill target.
• Oxide copper occurs mainly in fractures and veinlets. Fresh sulphides (pyrite, chalcopyrite and molybdenite) were observed below the volcanic rock cap in potassic alteration.
• Semi-continuous channel sampling over part of a newly constructed road cut ran 62 metres of 0.1% copper; 215 ppm molybdenum and 0.044 g/t gold. Sampling was limited to where the bulldozer was able to build the road and not necessarily cutting the best outcrop exposures.
• Geochemical zonation suggests use of pathfinder elements as well as mapping alteration mineralogy can be utilized to vector to the best drill targets.

Exploration Plans

Recent work has resulted in the following strategy and recommendations for continued exploration of the 1068 Project:

• Extend geological mapping over the northeast and southeast sections of the Project, up to 1 kilometre in each direction.
• Expand the previous rock-chip sample grid by a minimum of 500 metres to the southeast and northeast.
• Detail mapping of the phyllic alteration over the volcanic cap (lithocap) using pathfinder alteration minerals and the relative amounts of porphyry copper system vein types, to define specific drill targets.
• Commence drilling into the deeper core of the potassic alteration window (where current road cut sampling exists), as well as selected locations within the volcanic cap to test for mineralization suspected to occur beneath.

The Company plans to initiate the exploration programs as indicated. A more precise timetable of events will be disclosed over the next few weeks.

Exploration Results

The Chunibas Project is now viewed as a porphyry-related breccia gold system. Highlights include:

• Surface mineralized footprint of 3 kilometres X 1.5 kilometres and remains open.
• Gold mineralization occurs disseminated and vein controlled.
• The Company is encouraged to see three stages of mineralizing development, which are apparent in the discovery:
  1) initial property-wide emplacement of an igneous breccia which intruded older diorite and andesite rocks;
  2) a magmatic hydrothermal pulse where mineralising fluids emplaced disseminated gold in the breccias; and
  3) late, overprinting epithermal gold-bearing quartz-carbonate veins cross cut all previous rock types.
• Re-logging of the CHD-01 drill hole reveals it to host 88 metres grading 0.37 g/t gold disseminated in igneous breccias. The previously reported drill intercept in CHD 01 did not include this much wider zone of gold mineralization within breccias.
• Several drill holes cut magnetite-bearing potassic alteration associated with elevated gold grades. In some cases holes ended in significant, but previously unrecognized mineralization. The last assay in CHD-03 is 1.05 g/t gold and last assay in CHD-02 is 2.4 g/t gold.
• The alteration styles are indicative of a porphyry system.

For related images, please visit the Chunibas Project on the Company’s website.

Exploration Plans

Integrating the recent exploration recommendations with the current Chunibas database has generated an exploration strategy moving forward. The Company plans to immediately initiate the exploration programs as indicated below:

• Initiate a property-wide magnetic survey. There are indications gold mineralization may be associated with magnetite in potassic alteration. The magnetic survey could help map zones of potassic alteration beneath phyllically-altered rocks common at surface at Chunibas.
• Further explore the western sector of the property where highly altered rocks contain quartz-sericite-tourmaline structures possibly indicative of a porphyry system in close proximity.
• Extend several soil sample lines to the western area of the property to cover this zone.
• Use known pathfinder elements as well as magnetics for vectoring future drill hole locations.
• Drill defined targets to sufficient depths for an adequate test. Past drilling targeted the late epithermal vein zones at a shallow depth. The program wasn’t designed to test a porphyry gold system now suspected to be present. Deeper drilling will be required.

1068 Project

The Company is waiting on some final exploration information regarding the 1068 Project and expect to issue an update on that Project shortly.

It is now apparent that the drill hole collar locations, azimuths and depth of the recently completed six hole program were, essentially, “random” in relation to the newly discovered breccia system’s geometry and zoning since the Phase I drill holes being spotted based on a totally different geological model (see news release dated May 31,2017). Now that the Company recognizes an intrusive hosted gold breccia system with much larger scale potential exists, exploration will concentrate on defining and targeting this new system. Mapping, detailed sampling, review and integration of previous surface soil and rock chip sample data will be used by San Marco’s new team to generate a new geological model and vectoring process to target areas with higher grade potential for future drill campaigns.

To that end, the Company is pleased to have engaged Luciano Bocanegra to lead the team to re-map, sample, generate geological models and complete a vector analysis for the Chunibas property, as well as review similar analysis for the 1068 project. Mr. Bocanegra is currently Manager at Petra GAIA (a spectroscopy and exploration mining consulting company), located in Chile. As well, he is co-founder of a consulting company, Mineral Vector Services. Previous work engagements include services to Hochschild Mining plc and Rio Tinto plc in Argentina and Chile.

Bob Willis, San Marcos CEO stated, “Our core drilling, the first on the property, has allowed us to recognize a new Intrusive related gold breccia system, the magnitude of which is unknown at this time. The area will be remapped to determine the surface extent of the breccia. Our widely spaced Phase I drill holes indicate the breccia is open to depth and laterally in all directions. While we need to understand zoning and other possible controls on gold emplacement in order to target the best areas in future drilling, we are highly encouraged that most core containing breccia assayed to date exhibits at least anomalous (greater than 50 ppb) gold values. It will be exciting times as we work to define the magnitude of the system, refine and better understand the geological model and locate zones of mineralization with economic interest. San Marco is taking this discovery very seriously and has engaged a team of experts who will immediately create and execute an aggressive exploration program. We are targeting mid-September for the completion of a definitive go forward plan”.

Results and descriptions for holes 4 though 6 of the Phase I program are provided below. A map showing the location of the holes can be found at the following link: Chunibas Geology and Drill hole location July 20-17.

Hole CHD-04: Intersected breccia through the entire 202 metres of the hole. It appears that this hole is higher in the mineralized system, based on the elevated levels of pathfinder elements like arsenic and antimony, combined with lower gold values. This combination is typical of the higher levels of an intrusive related gold system.

Hole CHD 05: Drilled into what appears to be a residual block of non-eroded andesite (roof pendant). The hole did intercept breccia over 18 metres; including 2.0 metres of 0.28g/t gold ; 2 metres of 0.81 g/t gold, including 0.85 metres of 1.38 g/t gold.

Hole CHD-06: Primarily breccia; 25.2 metres of 0.18 g/t gold (including 9 metres of 0.25 g/t gold); 6 metres of 0.22 g/t gold; and 1 metre of 0.40 g/t gold and 11.5 g/t silver.

All holes were drilled at – 60 degrees inclination and at an azimuth (“az”) as follows: CHD-01 az 90 degrees; CHD-02 az 305 degrees; CHD-03 az 90 degrees; CHD-04 az 90 degrees; CHD-05 az. 90 degrees; and CHD-06 az 315 degrees. True widths are presently unknown, as the discovery holes do not have enough information yet to identify where the holes are located in the mineralized system.

Assaying for this drill program is being done by ALS Chemex located in Vancouver, B.C. Sample preparation is done at the Chemex lab in Hermosillo, Mexico, then pulps are shipped to Vancouver for analysis. Prepared samples are analyzed for gold by the Au – ICP21 method and multi-elements by ME – MS61, preparation 31B.

Drill core was sawn in half by a gas-powered diamond saw, then photographed and logged. One half of the core is sent for assay analysis and the other retained at the Company’s secure exploration facility in Sahuripa, Mexico.

Project 1068 – Drill permits received

The Company also reports receipt of SEMARNAT’s (Mexico’s environment ministry, Secretariat of Environment and Natural Resources) approval for drilling at the Company’s 100% owned 1068 copper/gold/moly porphyry project. Recent exploration activities included initial construction of access roads to drill pad locations. As the roads were side cut into relatively steep gully terrain, the porphyry intrusive body was exposed at various intervals along the road. Where the bulldozer managed to gouge deep enough into the side hill, visible copper oxides were noted over significant lengths. Continuous channel samples (each sample being 3 – 4 metres in length) were collected intermittently along approximately 200 metres where the road cut into the potassic core alteration. Assay results are expected shortly. Preparations for a maiden drill program at Project 1068 will begin in a few weeks, once roads have dried out after seasonal rains currently affecting the area.

Quality Assurance and Quality Control

The Company’s QA/QC program consisted of submission of duplicate samples and insertion of certified reference material and blanks inserted at regular intervals. These were inserted every 10 samples, or 10% of the total. Samples were bagged and tagged at the Company’s core facility in Sahuripa, Mexico and held in a secure environment, until being picked up by ground transport of ALS Chemex.

Bob Willis, San Marcos CEO stated,

“It is very early days, but we don’t want to understate the potential significance of this discovery. It’s too early to classify this new discovery though it has affinities to both breccia-hosted and intrusive-hosted systems, which are host to some large gold and gold-copper discoveries worldwide made in the recent past.

“Our core drilling, the first on the property, allowed us to log long contiguous sections of rock unaffected by surface weathering, something unavailable to past workers. This led to the discovery of the new intrusive breccia in all holes drilled so far, extending from the top to the bottom of the holes in most cases. Subsequent prospecting confirmed the breccia extends at least 200 metres west and 300 metres south of the Hole 1 and Hole 4 areas and it remains wide open. The area will be remapped to determine the surface extent of the breccia but early indications from our widely spaced drill holes is that it is fairly large. While we need to understand zoning or other possible controls on gold emplacement, we are highly encouraged that all core containing breccia assayed to date exhibits at least anomalous (greater than 50 ppb) gold values. It will be exciting times as we work to define the magnitude of the system, refine and better understand the geological model and locate zones of mineralization with economic interest. San Marco is taking this discovery very seriously and shareholders should expect more reporting on it in coming weeks. “

As indicated in the Company’s News Release dated May 31, 2017, the primary objective of the current drill program was to confirm the presence of higher grade mineralization within narrow (1 – 2 metres wide) shear zones, and possibly low-grade mineralization in the flanking wall rock. Exploration by previous property owners consisted exclusively of surface work and RC drilling. They concluded the Chunibas system was of the low sulphidation, epithermal type with mineralized shears / veins hosted in a monzonite intrusion. The San Marco core-drilling program was designed to test three separate areas of old workings and presumed shearing along approximately 1,000 metres of north-south strike.

Upon commencement of drilling and logging of the core, it immediately became apparent that the dominant rock type in the drill core is a multi-lithic (breccia fragments of different compositions) highly altered, intrusive breccia, and NOT monzonite. Two holes (drilled to the east at – 60 degrees) around the southernmost workings intersected breccia from the collars to total depth (154 metres and 201 metres respectively). Additional holes completed to date have intersected breccia as well. Drilling has now been concluded, with approximately 860 metres completed in the six core holes, see map Chunibas Geology and Drill hole location July 20-17*, for locations of drill collars from the current program as well as historic drilling. Following are the results of three holes, one each in the three areas of old workings over 1000 metres of strike. Results of remaining holes will be released when all assays are received and analyzed.

Highlights are:

Hole CHD – 01 39.0 metres of 0.67 grams per tonne gold

• Including 20.0 metres of 1.05 grams per tonne gold, 2.15 metres of 1.97 grams per tonne gold and 1.0 metre of 4.55 grams per tonne gold

Hole CHD – 02 21.0 metres of 0.58 grams per tonne gold,

• Including 1 metre of 6.78 grams per tonne gold, 1.20 metres of 2.42 grams per tonne gold at the bottom of the hole (i.e. hole ended in mineralization)

Hole CHD – 03 3.3 metres of 5.05 grams per tonne gold. Hole ended in mineralization with the final 2.2 metres grading 1.05 g/t gold (a separate interval)

Note; Hole CHD-03 intersected primarily diorite host rock rather than breccia, thus gold mineralization is primarily restricted to the higher-grade shear zone.

Early interpretation of these results indicates discovery of a breccia body, which has a significant footprint horizontally and vertically. Although breccia was previously identified in isolated outcrops, it was not systematically mapped nor recognized as an important host rock to mineralization. Holes CHD 01 and CHD 02 also exhibit anomalous gold (0.12 – 0.14 g/t over 30 -35 metres, higher up in the drill hole) in core, which does not appear to contain structures, suggesting gold may be disseminated in the breccia. All gold intercepts so far received are consistent with historical Reverse Circulation drill hole assay grades. The current drill program confirms gold mineralization exists from surface to approximately 75 metres below surface, and is open to depth, and in all directions laterally.

Based on review of the drill core and potential size implications of the breccia body, the next exploration steps will include;

• Receipt of and plotting / compilation of all drill holes assays.
• Merger of historic data together with 2017 results to generate 3D Leapfrog model to create a solid basis for additional exploration.
• Remapping of the surface geology, with particular attention to the distribution and types of breccia.
• Continue petrographic studies with emphasis on host rock textures, character of hydrothermal alteration, and the distribution and controls to gold mineralization
• Remodelling of all surface geochemical data to investigate potential pathfinder elements better suited to delineate the footprint of the breccias and identify / vector towards areas with higher grade mineralization.

Follow up drilling is expected to be commenced once targeting based on the new model is completed. Please see table below for complete listing of significant assays from holes reported today.

All holes were drilled at – 60 degrees inclination and azimuths of CHD-01: 90 degrees; CHD-02: 305 degrees; and CHD-03: 90 degrees. True widths are presently unknown, as the discovery holes do not have enough information yet to identify where the holes are located in the mineralized system.

Assaying for this drill program is being done by ALS Chemex located in Vancouver, B.C. Sample preparation is done at the Chemex lab in Hermosillo, Mexico, pulps are then shipped to Vancouver for analysis. Prepared samples are analyzed for gold by the Au – ICP21 method and multi-elements by ME – MS61, preparation 31B.

San Marco 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 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.
