September 9, 2021 - Bedford, NS - (TSXV:SSE) - Silver Spruce Resources, Inc. ("Silver Spruce" or the "Company") is pleased to announce the receipt of its report from Strategic Consultants IGIS, (“SCIGIS”) based in Chihuahua, Mexico, providing 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 (see Figure 1).

We continue to build on the Sonoran project geotechnical database using advanced processing techniques for re-interpretation of available ASTER and LANDSAT 8 OLI imagery. The TLALI algorithm processing clearly illustrated its capabilities in mineral and anomaly identification with clarity of spatial response,” said Greg Davison, Silver Spruce VP Exploration and Director. “We are compiling and interpreting the Shortwave Infrared (“SWIR”) and Visible to Near-Infrared (“VNIR”) hyperspectral data from El Mezquite and Jackie rock samples in concert with the ASTER/LANDSAT alteration fields for the next phase of drill target definition after recently completing our maiden drill program on EL Mezquite and Phase 2 geological and alteration mapping on Jackie. The SCIGIS maps also will be used for focusing and planning of the targeted geological mapping program at Diamante 1 and 2 in Q4 2021.”
The SCIGIS study comprised 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 research covered an area of 6,500 hectares - the map area shown in Figure 2. The ASTER imagery was 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 was carried out using LANDSAT 8 OLI imagery and focus on clay minerals, ferrous iron, and iron oxide species. The reporting included 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.
Project Geology - Spectral Response
The El Mezquite and Diamante properties each exhibit features that manifest with excellent hyperspectral signatures and responses for a broad suite of oxide and silicate minerals. The remote spectral response distribution, particularly for Jackie, is limited by extensive vegetation. A historical study of ASTER imagery was performed in 2017 principally on the Diamante and El Mezquite properties and identified hyperspectral responses interpreted as supergene oxidation and argillization with propylitic areas, the latter mainly in less altered andesites.
Figures 2 and 3 illustrate examples of the Servicio Geológico Mexicano (“SGM”) alteration and the recent LANDSAT 8 OLI interpretation for the three properties mainly for the Diamante and El Mezquite projects. Data available from the GEOINFOMEX SGM web portal displayed alteration with broadly circled areas of grouped minerals or styles. It is noteworthy that the Jackie property showed only minimal LANDSAT 8 OLI responses though the evidence from the current ground exploration successfully identified significant clay and oxide minerals proximal to the Au-Ag anomaly (see Press Releases – June 10th and June 26th, 2021).
El Mezquite - A white mica-dominant assemblage with lesser jarosite, kaolinite and iron oxides, distal zones containing chlorite, and intermittent areas of aluminous minerals locally linked to potential structural lineaments, were identified by the rock hyperspectral response. The LANDSAT 8 OLI TLALI maps illustrate northeast and northwest-trending clusters tied to surfaces exposure and topographic features including faults interpreted from the magnetic and 3D IP surveys. ASTER data documented, in Figures 3 and 4, the kaolinite, alunite and pyrophyllite group, with silica spatially associated with NW-trending lineaments and, in part, were targeted by the Phase 1 drilling. Additional targets to the south of the current drilling are interpreted from the TLALI alteration maps and the initial lineament analysis.
Jackie - The Phase 1 prospecting and Phase 2 mapping programs (see Press Releases - June 10th and June 26th 2021) identified a distinctive andesite ridge with intense oxidation, silicification, argillic alteration, and a notable vegetation-free zone. This location was confirmed by the ASTER and LANDSAT 8 interpretation though was limited to a focused area with ferric oxides, kaolinite, silica and chlorite-epidote-carbonate. The oxide and silicate alteration, was verified by aiSIRIS results of rock hyperspectral analysis, represented oxidized argillic zones with low grade or bleached metal values. Rock samples collected from the northern area of the ridge also displayed intense replacement by zeolite, kaolinite, alunite, montmorillonite, opaline silica, and muscovite and contained the bulk of the anomalous gold and silver values. None of this neighboring and significant alteration was recognized by ASTER and LANDSAT 8 OLI given the coverage by vegetation during the period of image collection. Compilation of the rock sample hyperspectral data is pending and requisite for advancing the alteration mapping of the Jackie property.

Diamante – Historical ground exploration on the Diamante 1 and 2 concessions identified mineralization accompanied by silicification, and phyllic, argillic, advanced argillic (quartz-alunite-pyrite) and propylitic (chlorite) zones, with overprinting by iron oxide and oxyhydroxide (hematite, goethite, and limonite) staining, jarosite and vuggy silica. The TLALI maps, shown in Figures 2 and 3 for the LANDSAT 8 OLI and combined LANDSAT/ASTER data, respectively, illustrate the spectral response for silicification and argillic alteration, including generic clay, alunite, pyrophyllite, kaolinite and silica, which are in part coincident with known artisanal vein workings and disseminated gold targets, such as the Southern Anomaly in Diamante 2. The areas of alteration require verification by surface exploration as part of the Phase 1 drill target definition program planned for Q4 2021.
