Initial Assay Results from 2022 Drill Program at Calico Silver Project Show Broad, High-Grade Silver and Expanded Gold Horizon
29.06.2022 | GlobeNewswire
VANCOUVER, June 29, 2022 - Apollo Silver Corp. (“Apollo” or the “Company”) (TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF0) is pleased to report its first assay results from the 2022 Drill Program at the Calico Silver Project’s Waterloo Property (“Calico” or the “Project”) located in San Bernardino County, California. Assay results continue to show near-surface, broad, high-grade silver mineralization. Results have also verified and expanded the gold mineralized horizon at the Barstow-Pickhandle contact, as discussed in the Company’s news release dated January 11, 2022.Results below are reported for 10 reverse circulation (“RC”) drill holes (see Table 1) which were drilled between early April and early May 2022. The 2022 Drill Program at Calico is proceeding as planned. A total of 37 holes (4,139.50 m out of a planned 10,000 m) have been completed as of June 26, 2022. Drilling is part of the multi-component 2022 Calico Technical Program, which aims to upgrade and expand the recently announced Inferred Mineral Resource Estimate (“MRE”) of 166 million ounces (“Moz”) of silver 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.

“I am very pleased with initial results from our ongoing 2022 drill program,” Apollo CEO Tom Peregoodoff stated. “Results from these first 10 holes validate the high-grade, shallow, and continuous nature of the silver mineralization at Calico. Further, they have verified and expanded the excellent gold target at Waterloo. Finally, they have added very valuable geological information that is being incorporated into the current drill program and will allow us to optimize the remainder of this work. With more than 1,500 samples currently being processed at ALS, shareholders can expect to see regular release of new assay results.”
SILVER ASSAY RESULTS
Silver assay results for 10 RC holes are reported in Table 1, with hole locations and information shown in Table 3 below. Nine of the 10 holes intersected near-surface zones of silver mineralization over and above the mineral resource silver cut-off grade of 50 g/t, and seven holes show intercepts of high-grade silver (greater than 100 g/t Ag) with most intervals being more than 50 m thick (drill hole length). In addition to further validating and infilling the high-grade, thick, and continuous nature of the silver mineralization, the results have added considerably to the Company’s understanding of the stratigraphy and controls on silver mineralization. This information is critical to advancing the confidence in the resource classification and optimizing the design of the remainder of the 2022 Drill Program. Refer to Figure 1 for drill hole locations and Figure 2 and Figure 3 for cross-sections of select silver results.

GOLD ASSAY RESULTS
Gold intercepts are reported for eight RC holes that intercepted the gold-mineralized horizon at the Barstow-Pickhandle contact (see Table 2 and Figure 1 below). Review of historic drilling and recent surface mapping by Apollo concluded that there is evidence to suggest that the entire 2.2 km long contact between the Barstow sediments and Pickhandle volcaniclastics is prospective for gold (see news release dated January 11, 2022). These latest drilling results show that the gold mineralized horizon is more laterally extensive and thicker than historic drilling indicated. Notably, new assay results show that:
- The mineralized gold footprint in the central portion of the Waterloo deposit has expanded from ~ 45 m along strike and 240 m down dip (as indicated by historic drilling by Pan American) to approximately 300 x 300 m; and
- The maximum true thickness of the gold-mineralized horizon drilled to date has increased from 25 m (see news release dated January 11, 2022) to more than 45 m (hole W22-RC-008, which terminated in gold mineralization).
Historic drilling and underground mining in the Burcham area to the southeast of the mineral resource footprint at Waterloo shows the areal extent of near-surface gold mineralization covers approximately 180 m by 450 m in that region. Very little of this gold footprint has been tested to depth. Drill holes are proposed to be completed as part of the 2022 Drill Program at Waterloo to infill information gaps in gold and silver mineralization between the central portion of Waterloo and the Burcham area (see Figure 1). In addition to this drilling, a total of 18 historic holes intercepted this continuous gold-mineralized horizon (based on currently geologic modeling) but were not analyzed for gold. Apollo is in possession of these pulps and will submit relevant intercepts for gold analysis. As part of the 2022 technical program, Apollo has recently completed a modest surface sampling program over the Burcham area to better characterize the nature of the geology and areal extent of mineralization in this region.

BARITE
Of the 10 holes being reported, major element analysis was undertaken on four holes (W22-RC-01, -002, -003B and -004B) to support rock type characterization and to provide a preliminary assessment of barite mineralization. Using a 2% barite cutoff grade, holes W22-RC-001 and W22-RC-002 showed 28 m to 45 m thick horizons of barite concentrations of between 2 to 13.9% from approximately 13 m down hole. Holes W22-RC-003B and W22-RC-004B showed little barite mineralization. As part of Apollo’s metallurgical test program, the purity and grade of barite is being assessed to determine if the barite at Calico meets or exceeds the minimum standards for drilling-grade barite as defined by the American Petroleum Institute. Barite (barium sulfate BaSO4) is one of 23 critical minerals listed in a new United States Geological Survey report that are defined as minerals essential to economic and national security and vulnerable to supply chain disruptions due to reliance on foreign imports.
SAMPLING AND QUALITY ASSURANCE/QUALITY CONTROL
Drilling is being undertaken by Cooper Drilling LLC, of Monte Verde, 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. Splits of prepared pulps are securely shipped from ALS Reno to ALS Vancouver, British Columbia for further analysis.
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 is 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 0.5 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. Four holes were analyzed for major elements using fused-disc X-Ray Fluorescence (method ME-XRF26). 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, 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.
ABOUT THE CALICO 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 at Calico
The 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 and disseminated-style deposits associated with northwest-trending faults and fracture zones and mid-Tertiary volcanic activity. The Project represents a district-scale mineral system endowment with approximately 6,000 m (19,685 ft) in mineralized strike length controlled by Apollo. Oxidized, disseminated and stockwork-style mineralization is primarily hosted in the Barstow sedimentary formation and is the subject of the MRE.
