Silver Spruce and Colibri report on Zn-Pb-Ag-Au mineralization at El Pillado target in 19- hole, 2,005 metre R/C drill program at Diamante project, Sonora, Mexico
Silver Spruce and Colibri report on Zn-Pb-Ag-Au mineralization at El Pillado target in 19-
hole, 2,005 metre R/C drill program at Diamante project, Sonora, Mexico
September 7, 2022 - Bedford, NS - (TSXV:SSE) - Silver Spruce Resources Inc. ("Silver Spruce"
or the "Company") , with its partner Colibri Resources Corp. (“Colibri”), announces promising
shallow intersections of base metal, silver and gold values from the first R/C drilling program on
the Diamante project (“Diamante” or the “Property”) . N ineteen (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).
“We are pleased to report the initial results from our maiden exploration drilling program on two
highly prospective areas of Diamante. Our first target, El Pillado, exhibited intervals of Pb and Zn
sulphide mineralization up to a combined 13.1 wt.% Pb+Zn, with elevated Ag to 397 g/t and Au
to 0.934 g/t, in variably altered andesite locally with shear/fault controls, comprising polymetallic
vein-style occurrences within and adjacent to historical artisanal mining,” stated Greg Davison,
Silver Spruce Vice-President Exploration and Director.

Media Release
“Geological logging and quantitative assays reported from one to six sulphide-bearing zones per
hole consistent with pXRF analyses conducted during the drill program. Anomalous values of Pb,
Zn, Ag and pathfinders including As, Cd, Cu, Hg and Sb, were confirmed over intersections of up
to 7.5 metres (e.g. , DIA22-05 24-30 metres and 43.5-51 metres),” Mr. Davison added. “ The
drilling confirmed the indicated El Pillado mine target, both shallow and at depth, and given the
promising metal grades in DIA22 -05 (AZ 105˚, -45˚) remains open to the east. Further ground
truthing will be prioritized for structural analysis and potential displacement vectors of projected
mineralization peripheral to underground workings. La Prieta drill results will be provided shortly.
Other high priority targets at Calton, Aguaje, El Chon, Mezquite Raizudo and several others await
ground-based activities. The Companies’ land position together at Diamante and other projects in
the area have significant exploration potential for a precious and base metals district opportunity
proximal to the Santana Mine, a pre-production Au project by Minera Alamos.”

Table 2. Select Assay Intervals from Phase 1 drilling at El Pillado target on Diamante Project (n=36 of
710 sampling intervals). Units of measure – 1 ppm = 1 g/t.
The initial five holes at El Pillado targeted E -W trending, shallow -dipping mineralization
straddling two normal faults or shear zones with one of the holes aimed to undercut the
mineralization looking for stacked zones or structural dilation targets parallel to the shallow
exposures and oblique to the shear/fault motion. Two holes were drilled from the northwest toward
the western extension of the know mineralization and several near-surface showings proximal to
N-S faulting and potential offsets of the main zone. The final two holes were proposed to test both
western extensions and southerly south -dipping targets beyond the initial geochemical sampling
window.

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. pXRF anomalies
were based on 90th and 95th percentiles for Pb, Zn, As, Ba and Sr values. Compilat ion of the full
ALS data package with the pXRF analyses identified a strong linear relationship for selected
metals and pathfinders which will now be applied both to drilling cost optimization and sample
selection protocols for the future Diamante drill programs.
Each of the holes intersected variably altered Tarahumara andesites and several hit one to several
intervals of the overlying dacite. Shear and fault features were interpreted from chip logging
within the andesites, and commonly associated with th e contact adjacent to dacite intervals.
Structural repetition of andesite and dacite in several holes may be represented in the sections due
to the east -west trending ‘normal’ faults indicated by the recent geological mapping program .
Alteration ranged fr om weak to moderate to strong in terms of silicification, chloritization and
carbonatization with local argillization due to weathering. Hairline veinlets of calcite, quartz and
sulphides were associated with mineralization - pyrite, galena, sphalerite, jarosite and hematite .
Highlights of the drill intersections shown in Table 2 and are noted below.
• DIA22-01 intersected five intervals to 3 metres with two sections exceeding 1% Zn.
• DIA22-02 cut six intervals to 3 metres with one section containing 3.89% Zn.
• DIA22-05 hit five intervals with significant metal values, including 24-30 metres (high
silver to 251 g/t Ag, Zn to 1.9 wt.%), 33-36 metres (Ag to 397 g/t, Pb+Zn to combined 11.2
wt.%), 43.5-51 metres (Ag to 257 g/t, Pb+Zn to 13.07 wt.%), 78-81 metres (Ag to 35.8 g/t,
Pb+Zn to 8.5 wt.%).
• DIA22-06 hit one zone of 3 metres (Ag to 60.4 g/t and Pb to 1.21 wt.%).
• DIA22-08 reported the highest gold of 0.934 g/t Au at a depth of 13.5 metres with low Ag
and base metal values.
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, many with parallel and branching structural control, and 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.
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 accompanied by high -grade
primary and supergene Pb+Zn+Cu up to a combined grade of 50.9 wt.% from grab and channel
sampling. 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 (Cu, Cd, Sb, Hg, As and Bi) are linked commonly to Pb
and/or 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).
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 precio us metal-dominant targets
also identified at Calton, El Chon and Aguaje.
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 drill-ready Diamante gold-silver (Au-Ag) property is located 5 km northwest of Tepoca, and
165 km southeast of the capital city of Hermosillo, eastern Sonora, Mexico. The Property is well
situated in terms of logistics for exploration and is ea sily accessible from Mexican Highway #16
which transects Diamante 1 and along several trails and dry river beds southward to Diamante 2.
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, Mexico.
Sample shipments comprising a total of 797 samples, including QA/QC insertions, to ALS Global
in Hermosillo were delivered on a weekly basis.
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 fac ility
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 processed by Four Acid Digestion followed by
Inductively Coupled Plasma Atom ic 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 Gravimetric 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).
Local chain of custody was monitored and maintained by the Project Geologist under the direction
of the QP. In-house quality control samples were inserted into the sample set by the Projec t
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 evaluated 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. 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.
Metal values disclosed herein by the Companies are reported from representative splits of drill
chip samples whereas those reported from grab and channel samples from earlier programs 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.
