Silver Spruce completes geological mapping on priority drill targets, new sampling reports
Au to 51.5 g/t, Ag to 2,270 g/t with Pb+Zn+Cu to 50.9 wt.% at Diamante, Mexico
April 27, 2022 - Bedford, NS - (TSXV:SSE) - Silver Spruce Resources Inc. ("Silver Spruce" or
the "Company") announces that the Company has received high-grade Au-Ag-Pb-Zn-Cu assays
upon completion of its Phase 1 geological mapping program on the principal drilling target areas
of the Diamante 1 and 2 concessions (see Press Release of January 24, 2022).
“We are pleased to report Au values to 51.5 g/t from silicified breccias in the Calton target (see
Figure 1) , 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, the latter
returning 2,270 g/t Ag, accompanied in several target areas 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 ,” stated Greg Davison, Silver Spruce Vice -
President Exploration and Director.

Calton, Calton Sur and Anomalía Sur on regional geology and graduated Au-Ag symbols.
“Significant zoned or multi -phase Au-Ag and/or base metal values from multiple targets spread
across the concessions validated the historical data and contributed to drill target prioritization.
Media Release
The significant impact of the polymetallic base metals to the project value proposition is
exemplified using Au -equivalent (AuEq) and/or Ag -equivalent (AgEq) grade determinations.
With our drilling permit now in hand, Silver Spruce, along with our partner Colibri Resource
Corp., look forward to awarding contracts for the initial 2,000 metres of reverse circulation (R/C)
drilling on the first-priority targets at La Prieta, Calton, Pillado and Aguaje with El Chon-El Chon
Oeste and Mezquite Raizudo next in line. Drilling quotations currently are under review for the
May-June 2022 program ,” Mr. Davison added. “The targeted geological mapping verified
moderate to intense silica, sericite, clay and propylitic alteration profiles within and peripheral to
mineralized veins and breccias transecting the Tarahumara andes ite tuff, overlying rhyolites and
late granodiorite (see Figure 1). Intersecting and splaying vein patterns with steep to moderately
dipping northwest, northeast and north -striking orientations were confirmed and spatially
coincident with parallel to obli que faults and shears which control and locally offset the
mineralization (see Figure 2).”

Calton - Mina Jacalon and Anomalía Sur targets showing branching arrays of veins and fault traces with
strike and dip, sampling locations for 2022 Au geochemistry on regional geology. Grid spacing 1 km.
Geological reports from the field team have corroborated and augmented the geological features
of polymetallic sulphide-rich veins principally hosted within sheared and altered andesites of the
Tarahumara Formation which dominates the geological exposure on Diamante (Figure 2). The
Calton and A nomalía Sur veins and/or stockworks also transect the younger rhyolite and
granodioritic intrusions. The veins commonly are 0.5 metres to 1 metre in apparent thickness and
are traced up to 200 metres along strike. 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 latera l drifts. 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, hematite and iron hydroxide.
Table 1 provides geochemical results for select samples (n=20 of 70) sorted by Au g/t from surface
and underground sampling of eight target areas on both Diamante 1 and 2 concessions. 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/or Zn.
Table 1. Diamante 1 and 2 Concessions - precious metal and multi-element geochemistry from twenty
(20) rock samples (n=70) from eight target areas collected during the 2022 geological mapping program.
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). Most of the 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.
Our high-resolution LiDAR mapping and review of the historical reports supplemented by the
2022 geological mapping have identified abundant additional surface workings (see Press Release
of January 24, 2022) , mainly small exploratory pits, some with artisanal minin g exhibiting
individual adits with or without crosscuts following vein and shear structures. Figure 3 illustrates
two of the high-grade targets recently sampled at El Chon and La Prieta.
The targets now planned for Phase 1 drilling include La Prieta, Aguaje and Pillado (see Figure 4)
and Calton (see Figure 1). El Chon -El Chon Oeste and Mezquite -Raizudo targets also are
permitted for drilling and available as warranted.

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.
Geological features of e pithermal 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 accompanied by phyllic, argillic, advanced argillic and propylitic zones, with near -
surface overprinting by weathering with iron oxide and oxyhydroxide staining, jarosite and relict
vuggy silica. Recent exploration verified pathfinder elements including As, Sb, Hg, Cd and Bi.
Structural lineaments with ENE, NE and NW orientations and branching, oblique vein sets to the
N-S direction correspond to known vein systems. These include vein targets at La Prieta, El
Cumbro, Mezquite Raizudo, El Chon, La Olla, Calton and Pillado. Dis seminated and stockwork
mineralization at Anomalía Sur and El Puerto offer bulk low-grade targets.
Mineralization is reported visually as pyrite, arsenopyrite, chalcopyrite, sphalerite, argentiferous
galena, argentite, hematite and probable metal oxides, carbonates and sulphates, including copper
carbonate (malachite), copper sulphates and plumbojarosite.

Geochemical Analysis, Quality Assurance and Quality Control
Rock and channel samples were delivered by the Project Geologist from the Property 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. 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 facility
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 fo llowed 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 are analyzed by Fire Assay with Gravimetric Finish Ore Grade
(Au-GRA21 o r 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, specifically Pb samples, were digested, as above, and
analyzed using Titration (Pb-Vol70).
In-house quality control samples (blanks, Rocklab Au standards 0.213ppm & 1.278ppm ) 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 were reviewed
by the Company's QP and evaluated with acceptable tolerances for 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 values 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.
