Apollo Defines Gold Mineralization over 1,000 metre Strike Length
at Calico
Reports 91.0 m of 0.390 g/t Au from surface and 211 g/t Au from surface grab sample
Vancouver, British Columbia, February 14, 2023 – Apollo Silver Corp. (“Apollo” or the “Company”)
(TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF0) is pleased to report gold (“Au”) assay results from the
Calico Silver Project (“Calico” or the “Project”) located in San Bernardino County, California. Results
reported herein are from the remaining five reverse circulation (“RC”) drill holes from Phase 2 of the 2022
Drill Program and new surface sample assay results.
• A
ll five drill holes intercepted Au above 0.100 g/t Au over significant thicknesses including
91.0 metres (“m”) of 0.390 g/t Au from surface (estimated 88 m true thickness) (W22-RC-
080).
• Surface sampling returned several high-grade results including 211 g/t Au (P715944) and
849 g/t silver (“Ag”) (P715962).
• Gold mineralization occurs stratigraphically below silver mineralization at Waterloo and
extends continuously across more than 1,000 m strike length and up to 400 m width . The
gol
d mineralized horizon remains open along strike.
• Initial cyanide solubility tests show recoveries ranging from 75% to 95% confirming gold
mineralization is oxidized and amendable to simple leaching.
• Gold mineralization represents a compelling prospect with the latest results providi ng
f
urther support for adding to the metal inventory for the upcoming mineral resource
estimate update.
New significant gold intercepts include:
o 0.390 g/t Au over 91.0 m from surface (W22-RC-080), including;
• 1.715 g/t Au over 1.5 m from 8.5 m down hole; and
• 1.771 g/t Au over 3.0 m from 41.5 m down hole; and
• 1.373 g/t Au over 3.0 m from 79.0 m down hole.
o 0.613 g/t Au over 65.5 m from surface (W22-RC-081), including;
• 3.62 g/t Au over 1.5 m from 4.0 m down hole, and
• 1.239 g/t Au over 6.0 m from 47.5 m down hole, and
• 1.100 g/t Au over 1.5 m from 58.0 m down hole.
o 0.353 g/t Au over 52.0 m from surface (W22-RC-082), including;
• 1.204 g/t Au over 4.5 m from 4.0 m depth down hole; and
• 2.05 g/t Au over 1.5 m from 34.0 m depth down hole.
o 0.567 g/t Au over 51.0 m from 35.5 m down hole (W22-RC-083), including;
• 1.673 g/t Au over 10.5 m from 58.0 m depth down hole.
Gold intercepts are reported at a 0.100 g/t gold cut-off grade (“COG”) with significantly higher-grade intercepts reported at a 1.00
g/t COG with a maximum of 4.5 m internal dilution and are uncapped. Lengths are down hole lengths and may not represent true
widths unless otherwise stated.

“These latest gold results from the Burcham area of the Waterloo Property confirm that the Calico Project
has a substantial oxide gold mineralized horizon,” commented Apollo’s President and CEO Tom
Peregoodoff. “This horizon which typically forms part of the footwall to our silver mineralization is extensive
and remains open. The spatial relationship between this defined gold horizon and the overlying silver
resource is consistent with the simple geometry of the overall resource and opens up additional
development optionality in the future. The successful delivery of the objectives of the 2022 program, and
the pending mineral resource update should confirm Calico is one of the largest undeveloped silver
deposits in the U.S. The potential addition of oxide gold to the mineral inventory will only increase the
overall investment attractiveness of the Calico Project.”
The 2022 Calico Drill Program, which is one component of the 2022 Calico Technical Program, comprised
9,840 m (32,283 feet) of drilling with 88 holes on the Waterloo property completed between April 5, 2022
and November 12, 2022. The 2022 Calico Technical Program aimed to upgrade and expand the previously
announced maiden Inferred mineral resource estimate (“ MRE”) at Waterloo of 116 million ounces of
silver contained in 38.9 million tonnes at an average grade of 93 g/t, which forms part of the Calico
maiden Inferred MRE of 166 million ounces of silver contained in 58.1 million tonnes at an average
grade of 89 g/t (see news release dated February 9, 2022)1.
Results for five RC holes are reported below, which total 483.5 m (1, 586 feet) and were completed
between November 8, 2022, and November 12, 2022. These drill holes were completed in the Burcham
area of the Wat erloo property , approximately 225 m southeast of the southern extent of the current
Waterloo silver MRE. These holes specifically targeted shallow oxide gold mineralization hosted in the
lower Barstow and Pickhandle formations . T he overlying Barstow stratigraphy, host to the silver
mineralization, is interpreted to have been eroded off in this area.
Also reported are gold and silver assay results from a surface rock grab sampling program completed in
the fall of 2022, in which 82 samples were collected across the Waterloo property to further understand
the distribution of gold mineralization at surface (following up results from 46 surface samples reported
September 14, 2022).
1The 2022 MRE was prepared by Derek Loveday, P. Geo. of Stantec Consulting Services Ltd., in conformance with Canadian
Institute of Mining and Metallurgy’s “Estimation of Mineral Resource and Mineral Reserves Best Practices” guidelines and are
reported in accordance with the Canadian Securities Administrators NI 43-101. It is effective January 28, 2022. Mineral resources
are not mineral reserves and do not have demonstrated economic viability. There is no certainty that any mineral resource will be
converted into a mineral reserve. Mr. Loveday is an independent Qualified Person for Apollo’s MRE. Please refer to the Company’s
news release dated February 9, 2022, for more information.
GOLD HORIZON
As previously reported (see news release January 11, 2022), a review by the Company of historic drilling
data for the Waterloo property identified a 25 m thick, gold bearing horizon stratigraphically below silver
mineralization and associated with the contact between the Barstow sediments and Pickhandle
volcaniclastics. The Burcham mine was the only mine in the district to have produced gold as its primary
commodity. The identification of these drill intercepts in the historic data suggested that gold mineralization
extended further north from the Burcham area than previously known. Further, surface geological mapping
completed by the Company in December 2021 identified evidence that the entire 2.2 km long
Barstow/Pickhandle contact at Waterloo is prospective for gold (see news release January 11, 2022).
Based on this work, one goal of the 2022 Calico Drill Program was to better understand the distribution
and styles of gold mineralization across the property. The drill program design included holes targeting
3
the prospective Barstow-Pickhandle contact at depth below the Waterloo silver MRE and along strike from
the Burcham area. It also aimed to verify historic drilling completed at Burcham and assess to what extent
the Pickhandle volcaniclastics may be mineralized with gold. All five drill holes reported herein
intersected gold mineralization across significant widths at or above a 0.100 g/t Au cut-off grade,
the longest intercept being 91.0 m of 0.390 g/t Au from surface. More than 74 m of this intercept is
hosted within Pickhandle volcaniclastics suggesting this lithostratigraphic unit may be more prospective
for gold than previously understood. Refer to Table 1 and Figure 1 for drill hole information and locations
and Table 2 for drilling gold assay results. Figure 2 shows the spatial relationship between the silver MRE
and gold in drilling results.

represent true widths.
Definition of gold mineralization is further supported by 2022 surface rock grab sampling for which a total
of 128 samples have now been reported. Surface sampling targeted historically and newly identified
northwest and north -south oriented high- angle structures, structural intersections, surface mapped
silicified rocks and bleached/brecciated fault gouge in the basal Barstow formation siltstones. Notable
results reported from the latest samples include 211 g/t Au, 7.14 g/t Au, 6.31 g/t Au, and 4.97 g/t Au
from the Burcham area. Refer to Figure 1 above and Table 3 below for locations and results for select
surface samples. Full results are listed on the Apollo website at the link provided below Table 3.
Results from drilling and surface sampl ing completed t o date at Waterloo show that gold
mineralization is spatially continuous along more than 1,000 m strike length (Figure 2) and remains
open along strike. Gold was intercepted in several holes 625 m further north of the current northern extent;
however, the continuity of the mineralized horizon in this gap and across the northern half of the Waterloo
property has not been fully tested.

GOLD CYANIDE SOLUBILITY
To assess gold recovery in a preliminary fashion, 66 samples from gold mineralized intercepts (0.100 g/t
Au cutoff grade) from three 2022 RC drill holes were selected for cyanide solubility testing, all of which
had been previously assayed using fire assay (see news releases dated June 29, 2022 and July 26, 2022).
Results of this preliminary testing show a range of average recoveries of 75-95% which confirms that gold
mineralization is oxide in nature and is amenable to recovery by traditional cyanide leaching methods
(Table 4). Additional metallurgical test work to better define gold recoveries is being planned as part of the
2023 Phase 2 Metallurgical program.

SAMPLING AND QUALITY ASSURANCE/QUALITY CONTROL
Drilling was undertaken by Cooper Drilling LLC, of Monte Vista, Colorado. RC chip samples were collected
in 1.5 m lifts with 15 lb representative samples sent for analysis. Representative chip samples were also
collected for logging purposes (lithology, alteration, mineralization), detailed photography and analysis by
portable X-Ray Fluorescence. RC samples are catalogued and securely stored in a warehouse facility in
Barstow, California until they are ready for secure shipment to ALS Global-Geochemistry in Reno, Nevada
(“ALS Reno”) for sample preparation and gold analysis. ALS Reno may selectively ship samples to other
ALS laboratories for preparation. After preparation, splits of prepared pulps are securely shipped to ALS
Vancouver, British Columbia for multi-element analysis.
Drilling and surface samples were prepared at ALS Reno (Prep-31 package) with each sample crushed
to better than 70% passing a 2 mm (Tyler 9 mesh, U.S. Std. No.10) screen. A split of up to 250 g was
taken and pulverized to better than 85% passing a 75-micron (Tyler 200 mesh, U.S. Std. No. 200) screen.
All samples were analyzed for 48 elements via ICP -MS following a four -acid digestion with reportable
ranges for silver of 0.01 to 100 ppm (method ME-MS61). Over-range samples analyzed for silver were re-
submitted for analysis using a four-acid digestion and ICP-AES finish with a silver range of 1-1,500 ppm
(method Ag-OG62). When results were over 400 ppm silver, they were re- submitted for analysis by fire
assay with a gravimetric finish using a 30 g nominal sample weight with reportable silver range of 5-10,000
ppm (method Ag-GRA21). Over-range samples analyzed for copper, lead and zinc were re-submitted for
analysis using a four-acid digestion and ICP-AES finish with range of 0.001-50% for copper, 0.001-20%
for lead, and 0.001-30% for zinc. Gold was analyzed by fire assay with atomic absorption finish (method
Au-AA26) with a reportable range of 0.01 -100 ppm Au. All analyses were completed at ALS Vancouver
except for gold by fire assay, whic h was completed at ALS Reno. For cyanide solubility testing, pulps
representing individual drill samples from within gold intercepts (at a 0.100 g/t Au cut-off grade) for which
fire assay gold results were previously reported were analyzed. Pulps were submitted to ALS Reno and
7
analyzed using method Au-AA13 (reported range of 0.03 to 50 ppm) which measures Au by cyanide leach
with follow up gold analysis via AAS.
The Company maintains its own comprehensive quality assurance and quality control (“QA/QC”) program
to ensure best practices in sample preparation and analysis. The QA/QC program includes the insertion
and analysis of certified reference materials, commercial pulp blanks, preparation blanks, and field
duplicates to the laboratories. Apollo’s QA/QC program includes ongoing auditing of all laboratory results.
The Company’s Qualified Person is of the opinion that the sample preparation, analytical, and security
procedures followed are sufficient and reliable. The Company is not aware of any drilling, sa mpling,
recovery, or other factors that could materially affect the accuracy or reliability of the data reported herein.
ABOUT THE PROJECT
Location
The Project is located in San Bernardino County, California and comprises the adjacent Waterloo and
Langtry properties which total 2,950 acres. The Project is 15 km (9 miles) from the city of Barstow and
has an extensive private gravel road network spanning the property. There is commercial electric power
within 5 km (3 miles) of the Project.
Geology and Mineralization
The Calico Project is situated in the southern Calico Mountains of the Mojave Desert, in the south-western
region of the Basin and Range tectonic province. This mountain range is a 15 km (9 mile) long northwest-
southeast trending range dominantly composed of Tertiary (Miocene) volcanics, volcaniclastics,
sedimentary rocks and dacitic intrusions. Mineralization at Calico comprises high-level low-sulfidation
silver-dominant epithermal vein-type, stockwork-type and disseminated-style associated with northwest-
trending faults and fracture zones and mid-Tertiary (~ 19-17 Ma) volcanic activity. Calico represents a district-
scale mineral system endowment with approximately 6,000 m (19,685 ft) in mineralized strike length
controlled by Apollo. Silver and gold mineralization are oxidized and hosted within the basal stratigraphic
horizons of the sedimentary Barstow Formation and in contact and within the upper volcaniclastic units of
the Pickhandle formation. The current mineral resource estimate at Calico comprises 166 million ounces
of silver contained in 58.1 million tonnes at an average grade of 89 g/t, at a cut-off grade of 50 g/t Ag (see
news release February 9, 2022).
