Lodestar Metals acquires Black Diamond Mining patent at Gold Run, Nevada

Vancouver, British Columbia--(Newsfile Corp. - April 16, 2026) - Lodestar Metals Corp. (TSXV: LSTR) (OTC PINK: SVTNF) (FSE: PR90) ( "Lodestar" or the " Company ") a junior exploration company focused on unlocking world-class gold potential in Nevada, is pleased to announce the acquisition of an important mining patent on its flagship Gold Run project. "The purchase agreement on the Black Diamond patent is another important step forward for Lodestar," said Lowell Kamin, President & CEO of Lodestar Metals. "Research into the mining history at Black Diamond and recent fieldwork have elevated the potential of this exciting prospect area and given us more flexibility to drill and unlock its value."

The Patent covers much of the Black Diamond structure, where historical records document high-grade silver mineralization that was historically mined. Under the 1872 Mining Act, surface and mineral rights on unpatented mining claims with established mineral potential could be transferred to private ownership, creating a patented mining claim. Lodestar executed a lease-and-purchase agreement for the Black Diamond Patent for the consideration set forth below.

This is a significant opportunity for Lodestar, given that the Patent has been held for over 100 years and has never been drilled. Previous work over the Black Diamond Patent has shown compelling evidence to support the validity of the target area for future exploration efforts: Extensive historical rock chip sampling, as well as that by Lodestar in 2024, demonstrates that silver mineralisation at surface ranges from 20 g/t and up to 3,307 g/t over at least 550 metres of strike (Figure 1) (see NI 43-101 Technical Report on the Gold Run property, May 12, 2025). Soil sampling by Lodestar shows a high tenor silver-in-soil anomaly over the Black Diamond Patent over the same 550m strike with soil values over 1 g/t silver and up to 33 g/t silver (see News Release Oct 28, 2025).

Historical DDIP work indicates at least one strong, untested chargeability anomaly along the western edge of the Black Diamond Patent (Figure 2), which is a target for the current round of drilling (see News Release Dec 2, 2025). New DDIP work by Lodestar Metals showed a second DDIP anomaly with depth extent down to 200m (Figure 2) along the western edge of the Patent area, further supporting the validity of the prospect area (see News Release March 10, 2026).

Rock chip assays by Lodestar at Black Diamond in 2024 indicate a close association of high grade silver with various other metals: gold up to 2.7 g/t, copper up to 0.5%, lead up to 1%, zinc up to 0.4% and pathfinder metals arsenic up to 1000 ppm, molybdenum up to 49 ppm, and antimony up to 955 ppm. This metal association suggests possible polymetallic, intrusion-related mineralization.

With the Black Diamond Patent lease, Lodestar has the flexibility to drill near-surface targets for silver mineralization. The Patent area is being assessed for drilling in the current program.

Upon acquisition of the Patent, Lodestar will grant a 2% net smelter return royalty to the vendor, which may be repurchased in its entirety for USD $75,000. Disclaimers 1 Summaries of drill targets and intercepts, and supporting technical data were provided in the Company's December 2, 2025, News Release. 2 The Company has identified historical drill intercepts in the Property's historical database, which was acquired.

The Company has not verified the intercepts, and there is limited available information regarding sampling methodologies, analytical procedures, and associated QAQC protocols. The historical intercepts are considered relevant for exploration targeting, which is intended to validate and assess the continuity and reliability of the reported mineralization. Readers are cautioned that the historical information should not be relied upon until it has been independently verified.
