Final Results of Phase 1 2022 Drilling Program Reported
Vancouver, British Columbia, September 14, 2022 – Apollo Silver Corp. (“Apollo” or the “Company”) (TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF0) is pleased to report assay results from a surficial rock grab sampling program and remaining assays from the Phase 1 2022 Drill Program at the Calico Silver Project (“Calico” or the “Project”) located in San Bernardino County, California. The surficial rock grab sampling and drilling programs are part of the 2022 Calico Technical Program, which aims to upgrade and expand the previously announced Inferred Mineral Resource Estimate (“MRE”) of 166 million ounces (“Moz”) of silver (“Ag”) contained in 58.1 million tonnes (“Mt”) at an average grade of 89 grams per tonne (“g/t”) (see news release dated February 9, 2022)1.
A surficial rock grab sampling program completed recently in the Burcham area, 225 metres (“m”) south of the Waterloo resource area, returned 34 rock samples with 0.1 g/t or more gold (“Au”), showing that this region represents a significant gold mineralized prospect outside the current MRE (see Figure 1 below). The surface program was designed to follow up on historic work completed in this area between approximately 1940 and 1989, showing the area exhibited gold mineralization across a broad area. Notable new surface rock samples reported include 6.280 g/t Au, 2.470 g/t Au, 2.410 g/t Au, and 2.240 g/t Au from subvertical, northwest oriented structures. These results, combined with drilling results to date confirm that gold mineralization is present over an extensive area at Waterloo (900 m X 400 m) over a variably thick horizon (approximately 5 m to 45 m true thickness).
In addition to these surface samples, final Phase 1 reverse circulation (“RC”) drilling assay results show that seven of nine holes reported herein intersected gold at the Barstow-Pickhandle contact. This latest drilling shows that gold mineralization is spatially continuous between the Waterloo Ag resource (116 Moz Ag contained in 38.9 Mt at an average grade of 93 g/t Ag) and Burcham areas. Gold mineralization represents a compelling prospect with the latest results providing further support for adding to the metal inventory for the upcoming mineral resource estimate update. These latest results will be followed up in Phase 2 of the 2022 Calico Technical Program which is expected to recommence in late-September.
As with all previously reported drilling results from the Phase 1 2022 Drill Program, silver mineralization correlates well with predicted block model grades, with three drill holes intersecting silver mineralization above the 50 g/t Ag cut-off grade (“COG”) used for the MRE, and one drill hole intersecting silver in excess of 500 g/t Ag.

“These results have confirmed the significant gold potential at Calico” commented Apollo CEO Tom Peregoodoff. “The surficial sampling combined with Apollo’s drilling have defined an extensive gold horizon that has never been fully delineated by previous operators. This horizon has the potential to add significant value to the Calico silver resource and further work is planned as part of the second phase of our 2022 Calico Technical Program to define this zone such that gold can be included in the upcoming revised resource estimate. With drilling set to commence this month, we are on track to deliver a revised resource estimate in early 2023 and will commence engineering studies shortly thereafter.”
SURFACE SAMPLING RESULTS
The surface rock grab sampling program was undertaken in July 2022 over a three-day period. A total of 46 rock samples were collected to confirm the historically reported disseminated nature of gold in the basal Barstow formation rocks in an area 225 m southeast of the Waterloo resource. This area, referred to as the Burcham area, hosted the Burcham mine, the only mine in the Calico mining district that produced gold as its primary commodity. The mine was active in the 1940s and comprised two underground drifts that exploited gold mineralized subvertical northwest oriented structures (refer to Figure 1). Total production figures are unknown. In 1985 and 1989, ASARCO completed 196.6 m of rotary drilling and 335.4 m of diamond drilling and sampled the underground workings at Burcham to determine the extent of mineralization in the Barstow-Pickhandle rocks. The new rock sample results follow up on and confirm that work and show that discrete sub-vertical structures host gold with concentrations varying from 1 to over 6 g/t Au in bleached and brecciated fault gouge in Barstow formation siltstones. The broader rock package across the sampled region (down to ~ 45 m depth) is mineralized with at least 0.1 g/t Au, hosted in variably silicified (cherty), bleached bedding horizons in the Barstow formation siltstones and sandstones. Refer to Figure 1 showing the distribution of surface rock samples reported herein.

The reader is cautioned that grab samples are selective by nature and do not necessarily represent the true metal content of the mineralized zones. Complete rock sampling results are available on the Company’s website.

DRILLING ASSAY RESULTS
Results below are reported for the remaining drill holes from the Phase 1 2022 Drill Program. These nine RC drill holes were completed between mid-June and early-July 2022, bringing the results released to market for the Phase 1 2022 Drill Program to a total of 42 holes (4,909.5 m), of the 44 holes completed (5,021.0 m). Two drill holes (W22-RC-003 and W22-RC-004) were not assayed, as there was evidence of material mixing during sampling at the drill rig. These two drill holes were re-drilled as holes W22-RC-03B and W22-RC-04B (reported in news release dated June 29, 2022).
Of the nine holes reported herein, four were MRE infill holes targeting near surface silver, and five aimed to target gold outside the southern margin of the current MRE. The holes targeting gold aimed to determine if the gold hosted at the Barstow-Pickhandle contact was continuous between the Waterloo resource and Burcham areas. Results show that it is continuous, and that the gold mineralization extends up to 900 m along strike. Refer to Figure 1 (above) and Table 2 (below) for drill hole locations and Table 3 (below) for gold results from drill holes.
Three of the nine holes intersected silver mineralization at or above the mineral resource silver COG of 50 g/t Ag. As expected, holes W22-RC-036 through W22-RC-041 confirmed the MRE-predicted lower Ag grade (< 50 g/t COG) in the southeast margins of the deposit and confirmed the continuous nature of Au in this region. Refer to Figure 1 (above) and Table 2 (below) for drill hole locations and information Table 4 (below) for silver assay results.

SAMPLING AND QUALITY ASSURANCE/QUALITY CONTROL
Drilling is being 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. Grab samples were collected in the field and a 2 kg representative sample was 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 and rock grab 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 laboratories, such as ALS Global-Geochemistry in Carson City, Nevada (“ALS Carson City”) for preparation. After preparation, splits of prepared pulps are securely shipped to ALS Vancouver, British Columbia for multi-element analysis.
Samples were prepared at either ALS Reno or ALS Carson City (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 is taken and pulverized to better than 85% passing a 75-micron (Tyler 200 mesh, U.S. Std. No. 200) screen. All RC 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 (method OG62) 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. Of the 46 surface rock grab samples collected, 36 were analyzed by method ME-MS-61 only, with the remaining 10 analyzed using complete characterization via the CCP-PK05 method which includes whole rock analysis (ME-ICP06), ME-MS61, single element trace method using aqua regia digestion and ICP-MS (ME-MS42) and rare earth elements using method ME-ME81 which consist of lithium borate fusion followed by ICP-MS. All surface rock samples were submitted for gold analysis by fire assay (Au-AA26). All analyses were completed at ALS Vancouver except for gold by fire assay, which was completed at ALS Reno.
The Company maintains its own comprehensive quality assurance and quality control (“QA/QC”) program to ensure best practices in sample preparation and analysis for samples. 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 from the laboratories. 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, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data reported herein.
