633 G/t Silver at the Buck Gold-Silver Property,
Central British Columbia
Vancouver, British Columbia--(Newsfile Corp. - September 28, 2020) - San Marco Resources Inc.
(TSXV: SMN) ("San Marco" or the "Company") announces results from its summer exploration program
and commencement of an induced polarization (IP) geophysical survey at its 100% controlled Buck gold
and silver property in central British Columbia, Canada.
The 22,000 hectare Buck property is located approximately 12 kilometres (km) south of Houston, British
Columbia, via an all-weather access road. It has excellent nearby infrastructure and allows for year round
exploration.
Phase 2 drilling is currently underway on the Buck property
(see SMN news release
dated
September 8
th
, 2020
).
Highlights
A 700 by 300 metre (m) multi-element soil anomaly, open to the north, was defined at Buck North
centered one kilometre north of historic drilling.
Grab samples returned assays of up to 13.3 grams per tonne (g/t) Au and 44.1 g/t Ag from the
Trench zone, and 11.1 g/t Au with 5.9 g/t Ag from the Horseshoe zone, confirming the presence of
higher grade epithermal-related mineralization throughout the Buck property.
A 20 line-km IP geophysical survey has commenced.
Five HQ diamond drill holes are now complete.
Rock Geochemistry
A program of geological mapping and rock sampling was completed in preparation for drilling. A total of
104 grab samples were collected from throughout the Buck property (
Figure 1
). Sampling was focused
primarily on the Buck breccia complex and the Buck structural corridor (see SMN news release dated
August 6
th
, 2020
).

Systematic sampling of mineralized, northwest-striking structures along Bob creek, which forms the core
of the Horseshoe zone, suggest that low-angle shear-zones carry higher-grade mineralization (sample
A0603848; Table 1) and that structural intersections with high-angle structures are also favorable hosts
for gold mineralization. The orientations of these structures and intersections helped inform the
orientations of some of the current Phase 2 diamond drill holes (see SMN news release dated
September 8
th
, 2020
).
The Trench zone comprises an area of historic trenching covering a footprint of approximately 200 by
220 m where local near-continuous Au mineralization has been reported from chip sampling and local
historic drilling (see SMN news release dated
June 23
rd
, 2020
). The zone is underlain primarily by
quartz-plagioclase porphyritic dacite and polymictic breccia that hosts clotted and vein-controlled pyrite-
sphalerite mineralization. Sampling of the trenches have returned many >1 g/t Au samples which confirm
historic data and also suggests a strong structural control. Additional structural mapping focused on the
higher-grade areas (sample A0603833; Table 1) in the Trench zone is warranted in order to refine drill
targets.
The Bob zone is 1.5 km west of the Horseshoe zone and consists of near-vertical, northwest striking
quartz-pyrite-arsenopyrite-sphalerite shear-hosted veins and vein-breccias that crosscut andesitic lapilli
tuff which have been exposed in historic adits and workings. These veins and vein breccias (2 to 50 cm)
have returned assays of up to 633 g/t Ag (sample R266334; Table 1). The extent of these veins is not
presently known and the area warrants detailed follow-up.
Grab samples are used to provide evidence of mineralization, however, grab samples are selective in
nature and the resulting assays from the samples may not be representative of all mineralization on the
property.
Soil Geochemistry
A recently completed 26 line-km soil grid consisted of 679 samples collected from 24 north-south lines
spaced 25 to 100 m apart with samples spaced 25 to 50 m along the lines. The center of the grid is
located one km northwest of the Horseshoe zone and one km north of the Trench zone where the bulk of
historic drilling has taken place (
Figure 2
). Within the northern grid, a 700 by 300 m multi-element soil
anomaly (Zn, Ag, As, and Pb) has been identified. This anomaly is open to the north. The east-west
trending, multi-element anomaly along Bob Creek (
Figure 2
) is interpreted to have been transported and
therefore limited significance is placed on the anomaly.

Geophysical Survey
A 20 line-km IP geophysical survey has now commenced. This north-south oriented survey consists of
nine lines spaced 200 m apart (
Figure 2
). The survey footprint covers the Buck breccia complex as well
as the recently defined soil-anomaly at the Buck North zone. This survey will have a significantly deeper
depth of investigation compared to historical 1980's-vintage surveys and the data will be used to refine
the current exploration model.
Health and Safety
The Company's exploration programs are being carried out in full compliance with federal, provincial,
and municipal guidelines established in response to the global COVID-19 pandemic. San Marco has a
rigorous infection prevention and control protocol in place to protect the health of employees,
contractors, as well as surrounding communities in which we work.
Quality Assurance
All sample assay results have been monitored through a quality assurance / quality control (QA/QC)
program. Samples were shipped in sealed and secure bags to the ALS Global laboratory in North
Vancouver, B.C. for analysis. Samples were prepared using standard preparation procedures. Soil
samples were analyzed for 53 elements by ICP-MS on a 25 gram sample using an aqua regia digestion
(method AuME-ST43). Rock samples were analyzed for 48 elements by ICP-MS on a 0.25 gram sample
using a four acid digestion (method ME-MS61L). Gold was analyzed by fire assay with an AAS finish
(method Au-AA23). Over limit gold (>10 ppm) was re-analyzed by fire assay using a gravimetric finish.
Over limit silver (>100 ppm) was re-analyzed using a four acid digestion and ICP-AES finish. Over limit
zinc (> 10,000 ppm) was re-analysed using a four acid digestions and ICP-AES finish. ALS Global is
registered to ISO / IEC 17025:2017 accreditations for laboratory procedures.
