Silver Spruce and Colibri hit mineralization at El Pillado and La Prieta Au-Ag-Pb-Zn-Cu
targets in 19-hole, 2,005 metre R/C drill program at Diamante project, Sonora, Mexico
August 3, 2022 - Bedford, NS - (TSXV:SSE) - Silver Spruce Resources Inc. ("Silver Spruce" or
the "Company") , with its partner Colibri Resources Corp. (“Colibri”), announces that their
Hermosillo-based team of geologists and service contractors has completed the first R/C drilling
program on the Diamante project. Nineteen (19) holes were drilled in its 2,005-metre program at
the La Prieta (10) and El Pillado (9) Au-Ag-Pb-Zn-Cu targets (Figure 1, Table 1). The drill-ready
Diamante gold-silver (Au-Ag) property (“Diamante” or the “Property”) is located 5 km northwest
of Tepoca, and 165 km southeast of the capital city of Hermosillo, eastern Sonora, Mexico.
“We are pleased to complete successfully our maiden exploration drilling program on two highly
prospective areas of Diamante. Our first two drill targets, El Pillado and La Prieta, exhibit ed
multiple intersections of sulphide mineralization, locally with fault controls , comprising
polymetallic vein-style occurrences within and adjacent to historical artisanal mining,” stated Greg
Davison, Silver Spruce Vice-President Exploration and Director.

the Pillado drill target, first DDH on the Diamante 1 concession.
“Geological logging reported one o r more sulphide-bearing i ntersections per hole and pXRF
analyses conducted on -site during the drill program provided clear ly anomalous values of base
metals, pathfinders and to a lesser degree, silver . Mineralized sections occurred over individual
1.5 metre sampling intervals and, with anomalous geochemical haloes, over contiguous intervals

up to 21 metres . From one to seven discrete pXRF anomalies per hole, based on 90 th and 95th
percentiles for Pb, Zn, As, Ba and Sr values, were indicated at both El Pillado and La Prieta,” Mr.
Davison added. “The initial batch of data from ALS Global (“ALS”) is in hand and under review
for the El Pillado drilling prior to release. We anticipate receipt and release of the remaining La
Prieta geochemical results from ALS shortly concurrent with interpretation of the geological
sections from both targets. Comparison of the current ALS data with the pXRF analyses identified
a strong linear relationship for selected metals and pathfinders which can be applied both to drilling
optimization and sample selection protocols for the future Diamante drill programs.”
Constructora Trax (“TRAX”) and Minera Drilling, both from Hermosillo, Mexico, respectively,
were contracted for the preparation of access trails and pads, and reverse circulation drilling holes
on the principal drilling target areas of the Diamante 1 and 2 concessions, specifically on the first-
priority targets at Pillado and La Prieta (Figures 1, 2, 3, 4 and 5).
Priority targets at Calton, Aguaje, El Chon-El Chon Oeste and Mezquite Raizudo are next in line
for a Phase 2 wor k program with several other promising targets awaiting additional ground
truthing activities.

The initial four holes at El Pillado targeted E-W trending, shallow-dipping mineralization. Five
additional holes were proposed at Pillado to test western extensions and southerly south -dipping
targets. Ten holes were completed at La Prieta, a ll of which are oriented to intersect depth
projections of known surface and shallow underground holes were inclined between -45˚ and -75˚
and drilled to depths ranging from 70 metres to 135 metres.
Samples were screened using pXRF analyses during the on-site logging to provide rapid qualitative
data for dynamic decision -making on drill hole planning and depth targeting (Figure 5). Four
sample shipments comprising a total of 1,586 samples, including QA/QC insertions, to ALS
Global in Hermosillo were delive red on a weekly basis (Table 1). The quantitative drill sample
results will be reported in due course.

Project Geology
The Property is located within the west -central portion of the Sierra Madre Occidental Volcanic
Complex within the northwest-trending “Sonora Gold Belt” of northern Mexico. Diamante offers
strong precious metal tenor with a polymetallic endowment, multiple quality targets, styles of
mineralization, of particular significance for our exploration moving forward, no records of
drilling. Historical exploration and artisanal activities are indicated by surface trenches and
subsurface workings parallel to and cutting the vein mineralization were measured up to 100
metres in length, with the latter showing shafts and short lateral drifts.
Geological features of epithermal Au, low to intermediate sulphidation Ag -Au (Pb -Zn), high
sulphidation Au-Cu, and potential porphyry style Au -Cu occur as disseminated, stockwork and
vein styles. Most drill targets are polymetallic vein style with precious metal -dominant targets
also identified at Calton, El Chon and Aguaje. Metal zoning or pulses of mineralization may be
indicated at each of these three locations.
Silicification with sericitic, argillic and propylitic alteration were accompanied by drusy to vuggy
quartz, black tourmaline, multiple disseminated to vein sulphides with incipient to pervasive
oxidation to carbonates, sulphates such as jarosite, hematite and iron hydroxide.
Our recent geological mapping programs conducted over multiple targets reported Au values to
51.5 g/t from silicified breccias in the Calton target (see Press Release of April 27, 2022), the
highest Au grade yet reported from Diamante, and Ag values >1,000 g/t were recorded from base
metal sulphide -bearing veins at Pillado, El Chon and El Cumbro ac companied by high -grade
primary and supergene Pb+Zn+Cu up to a combined grade of 50.9 wt.% from grab and channel
sampling at surface and within historical trenches and artisanal workings. Importantly, despite the
number and quality of known mineralization targets, there is no recorded historical drilling on
Diamante to date.
Figure 5. Company geologists utilizing portable X-ray fluorescence (pXRF) analyses on R/C drill chip
samples to guide daily drilling activities, hole depth, fan design and undercutting areas of visual
mineralization and those indicated by Cu, Pb, Zn, Ag and other pathfinder element data.
Specifically, geochemical results from surface and underground sampling of eight target areas
reported precious metals (Au to 51.5 g/t, Ag to 2,270 g/t), base metals (Pb to 42.3 wt.%, Zn to 22.9
wt.% and Cu to 3.2 wt.%) and pathfinders each exhibited weak to highly anomalous values
commonly with high Ag;Au and low to high Pb:Zn. Elevated Cu, Cd, Sb, Hg, As and Bi are linked
commonly to Pb and/o r Zn. The current assays are consistent with historical surface and U/G
channel samples reported up to 39.8 g/t Au, 3,460 g/t Ag, 18.2% Pb, 33.5% Zn and 1.47% Cu (see
Press Releases of April 12, 2021, and January 24, 2022).
Mineralization is reported vi sually as pyrite, arsenopyrite, chalcopyrite, sphalerite, argentiferous
galena, argentite, hematite and probable metal oxides, carbonates and sulphates, including copper
carbonate (malachite), copper sulphates and plumbojarosite.
Structural lineaments show intersecting and splaying vein patterns with steep to moderately
dipping northwest, northeast and north -striking orientations were confirmed and spatially
coincident with parallel to oblique faults and shears which control and locally offset the
mineralization.
Project Background
Silver Spruce can acquire up to 50% interest in four Diamante concessions with a cumulative land
position of 1,057 hectares (see Press Release of April 29, 2021).
The Property is well situated in terms of logistics for exploration and is easily accessible from
Mexican Highway #16 which transects Diamante 1 and along several trails and dry river beds
southward to Diamante 2.
Mining and exploration in the surrounding area is very active with adjacent and nearby properties
held by Alamos Gold, Argonaut, Agnico Eagle, Evrim, Newmont, Garibaldi, Kootenay Silver and
Penoles among others.
Geochemical Analysis, Quality Assurance and Quality Control
Drilling samples (¼ splits) were delivered by the Project Geologist from the Property to the ALS
sample preparation facility in Hermosillo, Sonora, Mexico. The remaining ¼ and ½ splits were
transported to Colibri’s storage facilities in Suaqui Grande, south of Tecoripa, Sonora.
ALS Global in North Vancouver, British Colum bia, Canada, is a facility certified as ISO
9001:2008 and accredited to ISO/IEC 17025:2005 from the Standards Council of Canada. Local
chain of custody was monitored and maintained by the Project Geologist under the direction of the
QP.
The samples were 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 were
transferred internally to ALS Global's North Vancouver, Canada or Lima, Peru analytical facil ity
for gold and multi-element analysis.
Pulps (50gram split) were submitted for Au analysis by Fire Assay with Atomic Absorption finish
(Au-AA24). The retained pulps also were 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 were analyzed by Fire Assay with Grav imetric Finish Ore Grade
(Au-GRA21 or Au -GRA22, Ag -GRA21). Overlimit base metals are 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). High grade samples above the
range of the Ore Grade OG62 analysis are digested, as above, and analyzed using Titration (e.g.,
Pb-Vol70).
In-house quality control samples were inserted into the sample set by the Project Geologist. ALS
Global conducts its own internal QA/QC program of blanks, standards and duplicates, and the
results are provided with the Company sample certificates. The results of the internal and ALS
control samples w ill be reviewed by the Company's QP and evalu ated for acceptable tolerances
prior to disclosure.
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.
All metal value s disclosed herein by Silver Spruce are reported from grab and channel samples
which may not be representative of the metal grades.
The Company’s Qualified Person believes that the sampling documentation, analytical protocols
and quantitative data will withstand scrutiny for inclusion.
