Silver Spruce Contracts ASTER and LANDSAT Spectral Analysis on El Mezquite, Jackie and Diamante Au-Ag Concessions, Sonora, Mexico
Silver Spruce Contracts ASTER and LANDSAT Spectral Analysis on El Mezquite, Jackie
and Diamante Au-Ag Concessions, Sonora, Mexico
June 30, 2021 - Bedford, NS - (TSXV:SSE) - Silver Spruce Resources, Inc. ("Silver Spruce" or
the "Company") is pleased to announce the signing of a contract with Strategic Consultants IGIS,
(“SCIGIS”) based in Chihuahua, Mexico to conduct a comprehensive interpretation of regional
ASTER (Advanced Spaceborne Thermal Emission and Reflectance Radiometer) and LANDSAT
8 OLI (Operational Land Imager) data over three exploration properties comprising El Mezquite,
Jackie and Diamante.
The 180-ha El Mezquite and 1,057-ha Diamante Concessions are drill-ready precious metal (Au-
Ag) projects located 10 km and 5 km, respectively, 165 km southeast of Hermosillo, Sonora,
Mexico. Diamante 1 is situated adjacent to the El Mezquite project. Diamante 2, 700 metres south
of Diamante 1, is located 1.6 k ilometres northwest of the 1,130-ha Jackie project. The Jackie
property is located less than two kilometres south of our El Mezquite and Diamante properties and
adjacent to the west of Minera Alamos' Santana project (Figures 1 and 2).

"We continue to build on the Sonoran project geotechnical data using advanced processing
techniques for re-interpretation of available ASTER and LANDSAT imagery. A review of the
TLALI algorithm processing results from many projects illustrated its success in anomaly
identification and clarit y of response ," said Mr. Davison, Silver Spruce VP Exploration and
Director. "We are actively exploring the El Mezquite with our maiden drill program , and another
team is continuing the Phase 2 geological mapping on Jackie , and look forward to compiling th e
hyperspectral data from rock samples and drill chips with the broad strokes of the
ASTER/LANDSAT alteration fields for enhanced target definition."

This study will comprise a spectral reconnaissance of the Properties (Diamante 1, Diamante 2, El
Mezquite, and Jackie) to understand the structural and lithological controls in a regional context
and provide additional detail on the mineral by mineral distribution over each of the Properties.
SCIGIS will research an area of 6,500 hectares. The ASTER imagery will be processed using the
proprietary TLALI algorithm, which has shown significant success in optimizing and recognizing
anomalies in a wide range of geological environments from several international projects.
A second run will be carried out using LANDSAT 8 OLI imagery and focus on clay minerals,
ferrous iron, and iron oxide species. The reporting will include a complete set of shapefiles, index
raster and RGB images, index reclassifications, and various digital elevation rasters with shading
and lineament extraction in ArcGIS format. Completion of the study will require 1-2 weeks.
Project Geology - Spectral Response
Each Property exhibits alteration features that manifest with excellent hyperspectral signatures and
responses for oxide and silicate minerals. Public data available through the GEOINFOMEX web
portal of the Servicio Geológico Mexicano (SGM) identified areas with potential alteration though
were defined by coarse pattern recognition of grouped minerals and overall styles.
Figure 2 illustrates examples of the alteration for the Diamante and El Mezquite projects. It may
be noteworthy that the Jackie property showed no responses though the evidence from the current
ground exploration successfully identified significant clay and oxide minerals proximal to the Au-
Ag anomaly (see Press Release – June 10, 2021). A historical study of ASTER imagery was
performed principally on the Diamante and El Mezquite properties and identified hyperspectral
responses with one or more minerals . However, during interpretation , the data pixels were
resolved using the principal mineral or group distribution.
Of note, the hyperspectral response may be limited by the vegetative cover, resolution of the older
satellite data and less advanced algorithms for the mineral refinement.
El Mezquite - The El Mezquite Phase 1 2,000 metre reverse-circulation (“RC”) program is using
eight drill pad locations focused around a 400m x 600m area with elevated precious metal values
to 3.41 g/t Au and 387 g/t Ag. The collar locations are defined by several northeast-trending veins,
structural lineaments, and oxide/sulfide transitions interpreted from geological mapping, precious
metal assays, multi-element geochemistry, epithermal alteration assemblages , and coincident 3D
IP chargeability anomalies (see Press Release - June 3, 2021).

Jackie - The preliminary prospecting program (see Press Release - June 10, 2021) identified a
distinctive andesite ridge with intense oxidation, silicification , argillic alteration, and a notable
vegetation-free zone. Geochemical analyses identified a strong Au -Ag anomaly associated with
elevated Hg, Pb, Zn, Cd, As, Sb , and Cu with spatial trends similar to the multi -element data
recorded for the nearby El Mezquite property. The extensive oxide and silicate alteration, verified
by preliminary aiSIRIS results of hyperspectral analysis, represented bleached and oxidized
argillic zones with aluminous clay minerals and muscovite and commonly low metal values.
Samples collected from the northern area of the ridge displayed intense replacement by zeolite,
kaolinite, alunite, montmorillonite, opaline silica , and muscovite though they contained the bulk
of the anomalous gold and silver values.
Diamante – The Diamante 1 and 2 concessions include more than ten known occurrences at La
Prieta-El Aguaje, El Chon-El Pillado, La Olla, La Cruz and El Caso, Mezquite Raizudo, El Puerto,
El Cumbro, Calton and the Southern Anomaly. The target location maps and sampling highlights
were provided previously (see Press Releases - April 12 and April 26, 2021). Precious metal
mineralization occurs as disseminated, stockwork and vein styles acco mpanied by silicification
(with quartz veining), and phyllic, argillic, advanced argillic (quartz-alunite-pyrite) and propylitic
(chlorite) zones, with near -surface overprinting by weathering, iron oxide, and oxyhydroxide
(hematite, goethite, and limonite) staining, jarosite, and vuggy silica.
Project Background
The Properties are well situated in logistics for exploration, located adjacent to each other, and six
to fifteen kilometers west and northwest of the Nicho deposit currently in mine development by
Minera Alamos (Figure 1).
The El Mezquite, Jackie, and Diamante projects are currently subject to option agreements with
Colibri, wherein SSE can earn 50% of the gold and silver projects by meeting specific criteria over
periods of two to four years . El Mezquite and Jackie concessions currently have hyperspectral
assays pending interpretation from Phase 1 mapping and prospecting, while the Company recently
received our SEMARNAT approval and initiated El Mezquite's maiden drilling program in June.

The Properties are easily accessible from Mexican Highway #16, which transects Diamante 1 and
El Mezquite, ranch trails and dry river beds to Diamante 2 , and dry river bed access from the
pueblo of La Quema, west of Highway #117 to Jackie. High voltage power lines positioned along
with Highway #16.
The Properties are located within the west-central portion of the Sierra Madre Occidental Volcanic
Complex within the prominent northwest -trending "Sonora Gold Belt " of northern Mexico and
parallel to the well-known, precious metals-rich Mojave-Sonora Megashear (Figure 3).

About Strategic Consultants IGIS
Based in Chihuahua, Mexico, Strategic Consultants have been in mineral exploration for over 30
years, having GIS and Remote Sensing as powerful tools to search for mineral deposits. Strategic
Consultants developed an innovative cloud -based algorithm capable of processing an ASTER
image anywhere in the world, in a matter of minutes, yielding up to twenty-five spectral signatures
representing the same amount of minerals, each in a separ ate ArcGIS shapefile. This procedure
allows to establish types of alteration, a rock -mineral relationship or geological -mineral
characteristic, and helps to select specific areas of interest and objectives. Major mining
companies, such as Agnico-Eagle México and Redline Minerals Inc. have used the algorithm for
exploration in brownfields and greenfields properties in México and the United States.
