In addition, a mapping and sampling program was recently completed at the Burcham gold prospect area in the southwest region of the Waterloo property (see news release dated February 12, 2025). This program confirmed the importance of the Calico fault system with respect to controls on the silver ("Ag)" and gold ("Au") mineralization in the area and has identified the potential for copper ("Cu"), zinc ("Zn") and lead ("Pb") mineralization associated with stratabound and mantos lenses.
Highlights:
- Mule claims expand the Calico Project land package by over 285%, from 1,194 ha to 3,409 ha of contiguous claims.
- Mule claims trend along the mineralized Calico Fault System responsible for mineralization seen at Calico.
- Reports from the prior operator indicate that there are several strongly anomalous silver values on the property, which Apollo will attempt to ground-truth in the coming exploration programs.
- Sampling done across the Mule claims by previous operator has  identified a large Ag anomaly associated with the same suite of host rocks at the Waterloo property.
- Exploration at the Burcham prospect at Waterloo included assays from 27 surface samples:
- Assay peaks up to 14.10 g/t Au, 20.70 g/t Ag, 0.17% Cu, 22.80% Zn and 5.74 % Pb from various samples (see Table 1).
- Identification of strata-bound lenses and mantos that show strong potential for Cu, Zn and Pb mineralization.
Ross McElroy, President and CEO of Apollo, commented , "The addition of the Mule claims substantially enhances the Calico Project. Calico already hosts 3 discrete drill delineated zones with resource estimates along a 4km long trend, along the Calico fault zone. The Mule claims increase the overall land area of the Calico project by more than 2.5x. The new claims are strategically located to the east along the very prolific Calico mineralized corridor and represent a great opportunity for further discoveries. Apollo is committed to continuing to unlock value in California for our shareholders."
Mule Claims Acquisition
The Mule claims are composed of 415 lode mining claims administered by the Bureau of Land Management. Mapping and sampling conducted by the previous operators across the Mule claims has identified a continuation of the mineralized Calico Fault System. The sedimentary rocks of the Barstow formation which hosts the Waterloo silver deposit, as well as the volcanic Pickhandle formation are pronounced all over the acquired claims. The contact between the Barstow and Pickhandle formation has demonstrated potential for gold mineralization as is seen at Waterloo. Sampling across the Mule claims has identified several strong Ag and Au anomalies. Apollo plans to conduct its own follow up exploration program on the Mule claims to better develop its own exploration targets and delineate where this highly prospective contact is exposed.
Details of the Transaction
The Mule claims were acquired by Apollo's wholly owned U.S. subsidiary, Stronghold Silver USA Corp. ("Stronghold"), from LAC. As consideration for the acquisition, Apollo paid US$250,000 in cash, and LAC retains a 2.0% net smelter return royalty (the "Royalty") on the Mule claims.
Apollo, through Stronghold, retains the right to buy back 1.0% of the Royalty at any time on or before the date that is thirty (30) days from the date of commencement of commercial production, for a payment of US$1,000,000.

2025 Burcham Exploration Program
The Company has completed its previously announced surface exploration work at its Burcham prospect (see news release dated February 12, 2025). The work completed consisted of detailed mapping, sample collection and target generation, with the aim to follow up with future drilling.
The exploration team has completed some of the most detailed mapping to date at the Calico Project, including previous programs at Langtry and Waterloo. Structures dominating at Burcham are similar to those at Waterloo with the system being dominated by the Calico Fault, a sinuous moderately plunging reverse fault that dips steeply to the north. Potential for Au mineralization is strong along the contact of the Burcham and Pickhandle formations. Previously unrecognised, stratiform mantos and lenses occupying fold flexures show strong potential for Cu mineralization. This type of mantos have been historically mined on the north side of the Waterloo deposit, and occur near the contact between the Pickhandle Formation and the overlying Barstow Formation. Historic mining on the North side of Waterloo Deposit targeted a manto about 1.5 m thick. Copper mineralization is associated with strong hydrothermal alteration which is seen to diminish as you move eastward along the property. Assays of the sample results are presented in Table 1.

Sampling and Quality Assurance/Quality Control
Grab samples were collected in the field and a 2 kg representative sample was sent for analysis. Rock 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. After preparation, splits of prepared pulps are securely shipped to ALS Vancouver, British Columbia for 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 250 g is taken and pulverized to better than 85% passing a 75-micron (Tyler 200 mesh, U.S Std. No 200) screen. Surface samples were analyzed using complete characterization via the CCP-PK05 methods, which include 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 the method ME-ME81, which consists of lithium borate fusion followed by ICP-MS. All surface samples were submitted for gold analysis by fire assay (Au-AA23). 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 a 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-AA25) 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.
Apollo's QA/QC program includes ongoing auditing of all 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 sampling issues or other factors that could materially affect the accuracy or reliability of the data reported herein.
