VANCOUVER, British Columbia, March 19, 2024 (GLOBE NEWSWIRE) -- Apollo Silver Corp. ("Apollo" or the "Company") (TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF0) is pleased to announce that it has received its Conditional Temporary Use Permit (the "Drill Permit") from the County of San Bernardino ("the County") authorizing 2024 drilling activities at the Waterloo Silver-Barite Property. Results from the 2024 assay testing program have been received and are being used to define planned barite assaying as part of declaring a maiden barite resource estimate at Waterloo.

HIGHLIGHTS

• 2024 Drill Permit for the Waterloo Property received from the County; and
• Barite analysis test program completed. Results will be incorporated into preparation for maiden barite resource estimate at Waterloo.

"The receipt of the 2024 Drill Permit ensures we can proceed with future drilling at Waterloo," commented Apollo's President and CEO Tom Peregoodoff. "The County took less than four weeks to issue the latest permit confirming their support for responsible resource development in the County. Results from the barite analysis testing program have enabled us to determine the most efficient and cost effective method for analyzing our drill material for barite. Our extensive pulps cover the entirety of the Waterloo deposit and this will provide us with a very good understanding of the distribution of barite and enable us to include this critical mineral in future resource updates for Calico."

BARITE ANALYSIS TEST PROGRAM
As reported on January 24, 2024, the Company began a test program designed to determine the optimal assay technique for barite. Using 79 samples distributed across the Waterloo Property, barite concentration was analysed to determine the best method to assay for barite. Results of this test work have been received and enable, a comprehensive re-assay program of select drilling pulps to be planned, with the goal of updating the Waterloo mineral resource estimate with the addition of barite.

In 1979 ASARCO calculated an estimate of barite in the Waterloo deposit. The estimate reported a total of 33.9 million tonnes of mineralized rock in the deposit at a grade of 13.4% barite for a total of 4.5 million tonnes of barite at a grade of 93%. Please refer to Table 1 for the results of and further information of this estimate and results are reported here as documented in original documents. The reader is cautioned not to treat this historical estimate or any part of it as a current mineral resource or reserve. An independent Qualified Person has not completed sufficient work to classify this as a current mineral resource or reserve and therefore the Company is not treating the historical estimate as a current mineral resource or mineral reserve.

^{Reference to the historic reserves at the Waterloo Property prepared by ASARCO refer to an internal company document prepared by ASARCO, dated 1979 (unpublished). Historic reserves are reported here as documented in original documents. The historic reserves were calculated prior to the implementation of the current Canadian Institute of Mining's ("CIM") standards for mineral resource estimation (as defined by the CIM Definition Standard on Mineral Resources and Ore Reserves dated May 10, 2014) as required by NI 43-101 and has no comparable resource classification. The reader is cautioned not to treat them, or any part of them, as current mineral resources or reserves. An independent Qualified Person has not completed sufficient work to classify these estimates as current mineral resources or reserves and therefore the Company is not treating the historical estimate as a current mineral resources or mineral reserves. The reliability of the historical estimate is considered reasonable, reliable, and relevant to be included here in that they demonstrated simply the barite mineral potential of the Waterloo Property. This historic resource estimate for silver has been superseded by the Calico Silver Project current mineral resource estimate, announced March 6, 2023. There is no current resource estimate for barite.}

MANAGEMENT UPDATE
Cathy Fitzgerald, Vice President, Exploration and Resource Development has announced her intention to step down from her role at Apollo effective April 26, 2024. Cathy was instrumental in advancing the Company and positioning Calico as one of the largest undeveloped silver projects in the USA. The board and management wish her all the very best in her future endeavors.

ABOUT THE CALICO PROJECT

Location
The Calico Project (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 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 15 km (9 mile) long northwest- southeast trending mountain range is 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. Gold and barite also form a significant component of the mineralized system. 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 sedimentary Barstow Formation and in contact with the upper volcaniclastic units of the Pickhandle formation. The current mineral resource at Calico comprises 110 million ounces ("Moz") silver ("Ag") classified as Measured and Indicated ("M&I") declared at Waterloo at an average grade of 100 grams per tonne ("g/t") Ag; and 51 Moz Ag classified as Inferred (720,000 oz Ag in the Waterloo deposit at 77 g/t Ag and 50 Moz Ag in the Langtry deposit at 81 g/t Ag) (see news release March 6, 2023).
