NS -- InvestorsHub NewsWire -- (TSXV:SSE) -
Silver Spruce Resources Inc.
("Silver
Spruce"
or
the "Company")
is pleased
to announce
the
discovery of a pristine exploration target with promising
Au-Ag
assay
results from
its Phase 1
prospecting and rock sampling
program
conducted over three weeks
on the 1,130-hectare Jackie Au-Ag property
("Jackie" or the "Property").
"Silver
Spruce
put the
technical
boots on the ground
and
our Hermosillo-based
geological
team
has
discovered
a
high quality,
broadly-zoned
geochemical
anomaly with multiple
mineralized
surface rock samples ranging up to 9.65 g/t Au and 515 g/t
Ag
with
intense
oxide and silicate
alteration,
and presence of base
metals and pathfinder elements,"
said Greg Davison, Silver Spruce VP Exploration. "Jackie
had
seen very little structured exploration and
our first
prospecting
program successfully
identified a
previously
untouched
Au-Ag
target
ready for systematic sampling.
The Phase 2 geological program scheduled for a late May
startup
will focus
on grid sampling and mapping
around our discovery
and on ASTER targets
noted
at higher elevations."
The Company recently signed a Definitive Agreement (Press release
November 30, 2020) with Colibri Resource
Corp. to
acquire 50% interest in
Jackie,
an early-stage precious metal project located 175 km east of
Hermosillo,
Sonora, Mexico.
The
large grassroots property (Figure 1) is located
in a very productive region
only
one to
two kilometres south from
our
El Mezquite
and Diamante
properties
and adjacent to the west of Minera Alamos' Santana
project.

Tepoca south on Highway #117
and local road to La Quema. Discovery area
3km
north of La Quema
is indicated by the white arrow.
The
Company, with a four-person team (two senior geologists and two
samplers) and all necessary logistical support, undertook a
Phase
1 exploration
program, including prospecting, rock, soil and stream silt/sand
sampling, and preliminary geological mapping of areas exhibiting
significant alteration or mineralization and collection of
structural data. The team focused on identifying and sampling
readily accessible areas of interest, confirming areas for future
detailed mapping and providing a geochemical baseline map for
vectoring toward potential Phase 2 targets.
All
aspects of the exploration program will be conducted with strict
adherence to COVID-19 protocols for personal safety.

Figure 2,
identified as one of the
early
exploration targets
from
aerial photography and review of
regional ASTER (Advanced
Spaceborne Thermal Emission and Reflectance Radiometer)
imagery,
shows a
distinctive andesite ridge with intense oxidation, silicification
and argillic alteration, and a notable paucity of
vegetation. Outcrop
exposures,
mapped
on a reconnaisance1:5,000
scale,
included
mainly
andesite in the
central valley and rhyolite tuff on the west and
southwest. The Property is
characterized by 300 metres of elevation from the river valley to
the cliff top plateaus.
A total
of 123 rock samples, plus duplicates and QA/QC standards and
blanks, were delivered to ALS for gold and hyperspectral analysis
using the Terraspec 4 and aiSIRIS identification of the principal
alteration minerals and their relative intensity.
Multi-element analysis was performed as results warranted from the
gold values and coincident with visual alteration
mapping.
The
prospecting sample locations are shown on the Property map in
Figure 3 and selected rock sample assays and analyses, sorted by Au
g/t, are displayed in Table 1.
The
extensive oxide
and silicate
alteration, verified by preliminary aiSIRIS results of
hyperspectral analysis, and seen in Figure 2 represented bleached
and oxidized argillic zones with aluminous clay minerals and
muscovite, and commonly low metal values.

anomalous Ag g/t, base metals and pathfinder trace
elements.
The
current suite of
samples
was
comprised of
kaolinite, dickite,
alunite, pyrophyllite, montmorillonite, saponite-nontronite,
opaline silica and jarosite in variable proportions. Zeolite
speciation to define temperature ranges was not
confirmed. Samples collected
from the northern area of the ridge as noted in Figure 4 also
displayed intense replacement by zeolite, kaolinite, alunite,
montmorillonite, opaline silica and muscovite
though contained the bulk of the anomalous gold and silver
values. Ubiquitous hematite with lesser jarosite and
secondary oxyhydroxides was identified on steep vertical exposures
(Figure 4) and in quartz vein
assemblages.
Further
interpretation of the hyperspectral minerals
and
potential
epithermal
alteration zones will be generated upon receipt of the final sample
batch and raw files from ALS and comparison with
property-wide
ASTER
and
LiDAR imagery.

sample JK9 - 9.65 g/t Au, 515 g/t Ag - intense low temperature
alteration including zeolite with lesser jarosite and muscovite
confirmed by aiSIRIS hyperspectral analysis.
Geochemical
analyses of precious metals clearly identified a strong Au-Ag
anomaly, commonly though not exclusively, associated with elevated
Hg, Pb, Zn, Cd, As, Sb and Cu. Gold-silver
ratios
are highly variable with
Ag
assays
generally low and the highest
silver values are linked to the best gold assays.
Hg
shows a strong positive link
to
Au-Ag as does
Zn-Cd
though
each element displays a wide range down to background
values. Copper,
arsenic and antimony display a more diffuse spatial
pattern
with lateral extent and Ba-Sr exhibit an inverse relationship to
precious metals with both trends similar to the multi-element data
recorded for the nearby El Mezquite property.

geochemical
anomalies,

on 75th,
90th,

and
98th
percentiles,

for
gold,
arsenic and strontium. The additional geochemistry
and
geological maps and
images from the field
program will be provided on
the updated Silver Spruce web site (www.silverspruceresources.com)

Location Map of Jackie
Property and Mines of the Sierra Madre Occidental
The
Property is situated
approximately six
kilometres
northwest
of the Nicho deposit currently under mine development by Minera
Alamos.
Other
nearby large operating mines include Alamos Gold's Los Mulatos gold
mine and Agnico Eagle's La India gold mine located
50-60
km to
the northeast, Agnico Eagle's
Pinos Altos Mine, 95
km
southeast and Argonaut's La Colorada Mine, 100 km
to
the west.
Exploration is very active with adjacent and nearby
properties reported to
be held by
Minera
Alamos, Newmont,
Garibaldi, Evrim,
Kootenay Silver and
Peñoles.
The
1,130-hectare Property is easily accessible from Hermosillo
to the
Tepoca area and heading south
from Mexican Highway #16 or west from
Highway #117,
or
from
Ciudad Obregón travelling northeast
on Hwy.
#117
and
west to the pueblo of La Quema with vehicles
and then
pack
teams along dry river beds,
dirt roads and trails. The
southerly road from Hwy #16 traverses through the centre of the
known gold mineralization at El Mezquite only
2
km north of
Jackie. High voltage power lines are positioned
on
Highway
#16.
Project Geology
The Miocene-age lithologies are represented by the Baucarit
Formation consisting of intercalated polymictic conglomerate,
sandstone and 'limonite' overlying the Tepoca Formation represented
by porphyritic andesite at the base, and basalt and basaltic
andesite at the top of the section.
The
Baucarit conglomerate unit is represented by unsorted pebbles to
large cobbles of andesite and basalt of different sizes, from 1cm
to 20cm in diameter, exhibited moderate to strong
silicification. The Tepoca basalt
underlying the conglomerate displayed a porphyritic texture with
moderate silicification. Neither
unit exhibited evidence of any mineralization.
Tepoca
andesite is similar to the above unit though with light gray color
when fresh and reddish color on exposure, displayed moderate to
intense oxidation and alteration, with hematite and associated Fe
oxide/oxyhydroxide, jarosite and Mn oxides. Silicate
alteration
comprised
weak
sericitization
and
moderate to strong silicification, weak to moderate argillization
and veinlets of quartz and hematite.
Transecting the
andesite in a northeasterly strike were narrow 1 to 1.5 metre
wide, lineaments
of brecciated andesite
with monolithic fragments,
abundant hematite,
jarosite, moderate to strong silicification, and traces of very
finely disseminated pyrite.
Rhyolitic crystal
tuff units,
located to the west and
southwest, presented moderate
to strong silicification, moderate veinlets of chalcedonic silica,
and narrow stringers of calcite with quartz crystals, weak
oxidation to hematite and weak to moderate propylitic alteration
(chlorite-carbonate). Precious
metal values were very low to below detection limits.
Geochemical Analysis, Quality Assurance and Quality
Control
Rock samples
were 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 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 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 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 Gravimetric Finish Ore Grade (Au-GRA21 or Au-GRA22,
Ag-GRA21). Overlimit base metals were 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) were inserted into the sample set. ALS Global
conducts its own internal QA/QC program of blanks, standards and
duplicates, and the results were provided with the Company sample
certificates. The results of the ALS control samples were
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.
All of the 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 has reviewed the current QA/QC
certificates and believes the sampling, analytical protocols and
data will withstand scrutiny for inclusion.
