August 5, 2021 - Bedford, NS - (TSXV:SSE) - Silver Spruce Resources Inc. ("Silver Spruce" or the "Company") is pleased to announce the completion of its Phase 1 exploration drilling at the El Mezquite Au-Ag property ("El Mezquite" or the "Property"). A total of 2,485 metres were drilled in twenty (20) holes covering eight collar locations. The first seven (7) drill holes were completed on June 14th and the Company is anticipating the final results of gold, silver and multi-element analyses by mid-August. The remaining thirteen (13) holes were drilled with two RC rigs from Layne de Mexico and completed as scheduled on July 28th.
"We were pleased to expedite exploration with additional geologists and samplers, and equipped with a second drill, Silver Spruce completed over 1,500 metres during July 21st to 28th. Logging and splitting of samples are progressing quickly at our option partner Colibri Resource's office facilities in Hermosillo. Samples will be submitted to ALS Global through the first week of August and, during September, we are looking forward to assays which reflect the potential of the outcrop samples," stated Greg Davison, Silver Spruce Vice-President Exploration and Director.

"The Phase 1 RC program (see Figure 1 and Table 1) comprised 20 holes with a combined depth of 2,485 metres and utilized 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. Collars were defined by several northeast-trending veins, structural lineaments and oxide/sulphide transitions interpreted from geological mapping, precious metal assays, multi-element geochemistry, epithermal alteration assemblages and coincident 3D IP chargeability anomalies," said Mr. Davison. "New targets for Phase 2 drilling are developing from our ongoing geological, hyperspectral, LANDSAT and LiDAR compilation, and incoming drill results as available."

The Company's first-ever drilling program at El Mezquite was completed in July with samples being submitted to ALS Global in Hermosillo in daily batches of 3-4 holes. Laboratory assay results generally are expected from four to eight weeks after submittal. Laboratory workloads have impacted the projected turnaround timelines for the assays. The data will be released once the final precious metal and multi-element results are in receipt and interpreted for the first seven (7) drill holes, and for the remaining thirteen (13) drill holes, and all of which will contribute to the program design for Phase 2 drilling after the summer rainy season.
El Mezquite, a drill-ready precious metal project located 10 km northwest of the town of Tepoca, and 170 km southeast of the capital city of Hermosillo, eastern Sonora, Mexico, is very well situated in terms of logistics for exploration and is located only twelve kilometres northwest of the Nicho deposit currently under mine development by Minera Alamos (see Figure 2).

The Company undertook an exploration program including environmental permitting for drilling, geological mapping of geologic structures and lineaments, ortho-mosaic photography, rock geochemical and hyperspectral analysis, data compilation and GIS modeling, and a LiDAR survey. Ground truthing of the Au-Ag system with geological mapping and rock sampling was completed in three campaigns between July 2020 and March 2021. All aspects of the exploration program are conducted with strict adherence to COVID-19 protocols for personal safety.
All current samples from the 2020-2021 field programs were submitted to ALS Global for gold, multi-element and hyperspectral analysis. Historical samples (>400) from the 2010-2019 programs also were submitted to provide complementary multi-element and hyperspectral data over the Property database. The assays, LiDAR survey data, and satellite hyperspectral interpretation results are being updated into the project ArcGIS database.
RC Drill Program
The environmental permit, required to drill the Property, was received from SEMARNAT (see Press Release April 20, 2021) and granted to the concession holder, Yaque Minerals S.A. de C.V. ("Yaque") by the Mexican Secretariat of Environment and Natural Resources (SEMARNAT).
The permit allows for fourteen (14) drill pads over the targets in the northern area of the concession. Individual holes achieved depths of 100-200 metres to intersect the target intervals.
Land surface agreements were signed recently with three ranchers to facilitate full access to the Phase 1 collar locations.
The 180-hectare Property is easily accessible from Mexican Highway #16 via a southerly-trending unpaved road which traverses through the centre of the known gold mineralization (see Figure 2). High voltage power lines are positioned along Highway #16.
The El Mezquite Project is 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.
Geochemical Analysis, Quality Assurance and Quality Control
Drill chip sample splits are delivered to the ALS sample preparation facility in Hermosillo, Sonora, Mexico. ALS Global in North Vancouver, British Columbia, Canada, is a facility certified as ISO 9001:2008 and accredited to ISO/IEC 17025:2005 from the Standards Council of Canada.
The samples are crushed to 70% passing 2mm (PREP-31) and a split of up to 250 grams pulverized to 85% passing 75 micrometres (-200 mesh). The sample pulps and crushed splits are transferred internally to ALS Global's North Vancouver, Canada or Lima, Peru analytical facility for gold and multi-element analysis. Pulps (50gram split) are submitted for Au analysis by Fire Assay with Atomic Absorption finish (Au-AA24).
The retained pulps also will be analysed by Four Acid Digestion followed by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) multi-element analyses (ME-ICP61m) with Hg by Aqua Regia and ICP-MS (Hg-MS42).
Over-limit Au and Ag samples will be analyzed by Fire Assay with Gravimetric Finish Ore Grade (Au-GRA21 or Au-GRA22, Ag-GRA21). Overlimit base metals will be analyzed by Four Acid Digestion followed by Ore Grade Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) for Cu, Pb and Zn (Cu-OG62, Pb-OG62, Zn-OG62).
In-house quality control samples (blanks, standards, duplicates, preparation duplicates) are inserted into the sample set. ALS Global conducts its own internal QA/QC program of blanks, standards and duplicates, and the results will be provided with the Company sample certificates. The results of the ALS control samples are reviewed by the Company's QP and evaluated for acceptable tolerances.
All sample and pulp rejects will be stored at ALS Global pending full review of the analytical data, and future selection of pulps for independent third-party check analyses, as requisite.
