Solitario drills 1.2 m of 1,445 g/t Ag at Golden Crest

Executive Summary

• Solitario Resources reported a high‑grade silver intercept of 1,445 g/t Ag (46.5 oz/ton) over 1.2 m in drill hole GC‑012 at the Golden Crest project.
• Phase 1 drilling is now complete with 7 holes (2,653 m) added this summer, bringing total historic drilling to 18 holes (≈7,000 m); assays pending for three holes.
• The company is preparing to commence Phase 2 drilling on the Ponderosa target as soon as U.S. Forest Service permits are received, targeting a late‑October start and planning >40 new drill locations.

Key Details

• High‑grade silver intercept: 1,445 g/t Ag (46.5 oz/ton) over 1.2 m in hole GC‑012 between 164.0–165.2 m depth.
• Associated mineralization: Core above and below the silver zone is being assayed; adjacent holes GC‑012X and GC‑013 contain multiple >30 ppb Au intervals, up to 0.57 g/t Au with elevated pathfinder elements.
• Phase 1 drilling summary: 7 new holes (2,653 m) added in the 2025 summer field season; total historic drill program now 18 holes (≈7,000 m). Seven of the first 15 holes intersected significant mineralization. Assays pending for the final three holes.
• Phase 2 drilling plan: Awaiting U.S. Forest Service permit decision; targeting a late‑October start. Permit window runs May 15 – Dec 15. Program will include >40 drill hole locations on the Ponderosa side of Golden Crest.
• Gravity survey: Initiated to cover Ponderosa and additional targets at Golden Crest, intended to refine geological understanding and prioritize drill targets before resuming core‑rig operations.
• QA/QC procedures: Core samples processed by American Assay Laboratories (Reno, NV) with full chain‑of‑custody, duplicate, blank, and standard inserts; fire assay protocols described in detail.
• Qualified person: Technical disclosure reviewed and approved by Walter Hunt, QP under NI 43‑101.

Notable Quotes

“We were surprised to intersect this very high‑grade silver intercept in GC‑012… As we await approval of the Ponderosa drilling permit, Solitario is launching a gravity survey… to sharpen our understanding of the geologic architecture of the district and prioritize the most compelling drill targets.” – Chris Herald, President & CEO

Materiality Assessment: Material – Positive (significant high‑grade intercept and advancement of exploration program.)
