Silver Range Expands Alamo Gold-Copper Target

Executive Summary

• Silver Range Resources announced recent exploration results at its Alamo Property in Arizona, highlighting significant gold and copper geochemical anomalies and geophysical conductors.
• Soil sampling identified peak gold responses of 1.34 g/t and copper of 649 ppm, while rock and float samples returned up to 21.8 g/t gold and 6.99% copper.
• VLF-EM surveys revealed an extensive network of coalescing conductors coincident with the geochemical anomalies, expanding the exploration target to over 1.6 km in length.

Key Details

• Survey Scope: Soil geochemical and VLF-EM surveys were conducted in December 2025 and April 2026, collecting 481 soil samples at 25m intervals on 100m-spaced lines, alongside 11.7 line-km of VLF-EM coverage.
• Soil Geochemistry: Peak gold response of 1.34 g/t Au and peak copper response of 649 ppm Cu were identified across the surveyed grid.
• Rock/Float/Grab Assays: 23 samples were collected, with 2 returning >5 g/t Au and 6 returning >1% Cu (10,000 ppm). Notable high-grade results include:
• 25-TT-1: 21.8 g/t Au, 69,900 ppm Cu
• 25-RP-1: 12.75 g/t Au, 27,100 ppm Cu
• K417902: 1.61 g/t Au, 28,600 ppm Cu
• K417911: 1.61 g/t Au, 12,550 ppm Cu
• K417904: 0.82 g/t Au, 22,200 ppm Cu
• Geophysics: VLF-EM survey utilized the Jim Creek, WA station and identified a network of locally coalescing conductors, with portions coincident with anomalous soil geochemistry and high-grade rock samples.
• Exploration Target: The target area has been expanded to over 1.6 km in length.
• Property Geology & History: The property hosts detachment fault-related IOCG mineralization within a metamorphic core complex. Historically mined (1909–1929) in the Cunningham Pass Mining District, with the Wenden Mine reporting grades of 0.5 OPT Au and 9.65% Cu down to 300m depth.
• Royalty Interest: Altius Minerals Corporation holds a 1% net smelter return (NSR) on the Alamo Property pursuant to a March 2023 agreement.
• QA/QC & Laboratory Analysis: Samples were shipped under chain of custody to ALS Minerals and Paragon Geochemical in Reno, NV. Gold was analyzed via fire assay with atomic absorption finish, and multi-element analysis was performed via ICP-MS/ICP-OES. Overlimit copper samples were re-analyzed using ore-grade techniques.
• Future Plans: The Company intends to continue exploration using geological, geochemical, and geophysical techniques to locate mineralization under cover.
