Lodestar Metals Enters into Exclusivity Agreement on Silver Projects in Eureka Silver District, Nevada

Vancouver, British Columbia--(Newsfile Corp. - September 8, 2025) - Lodestar Metals Corp. (TSXV: LSTR) (OTCQB: SVTNF) ("Lodestar" or the "Company") is pleased to announce it has entered into an exclusivity agreement with a group of arm's-length vendors to negotiate the terms of an agreement to option silver-focused unpatented mineral claims in West Eureka, Nevada (the "Eureka West Project").

Lowell Kamin, President and CEO of Lodestar stated: "Eureka West gives us a chance to keep moving things forward in Nevada. Having a second opportunity here is a structurally important step for the company, and with strong historical results on the ground that hasn't seen modern exploration, it's an exciting addition as we continue advancing our portfolio."

The West Eureka Project consists of an initial 20 unpatented lode claims located within the prolific Battle Mountain - Eureka Trend (Figure 1). The West Eureka Project is relatively unexplored; grab samples previously taken by the vendors include: up to 378 g/t silver, 1.1% copper at Silver King prospect; up to 277 g/t silver, 2.7% copper at Angel prospect; and up to 254 g/t silver, 0.4 g/t gold and 7.7% lead at Jag prospect.

Company personnel recently visited the Eureka West Project to assess its geology and mineralization. While due diligence on the property is ongoing, several historical shafts have exposed two primary mineralization types: carbonate replacement at the Jag prospect (Figure 2, left); and fault breccias at the Angel prospect (Figure 2, right).
