Solitario intersects 1,445 grams/tonne of silber over 1.2 meters

Solitario (XPL) Resources intersected 1,445 grams per tonne silver in drill hole GC-012. This high-grade interval represents an unrecognized style of precious metal mineralization not only for the Golden Crest project, but unique compared to mineralization in the historic Homestake and Wharf mining areas, The high-grade silver intercepted in hole GC-012 between 164.0 to 165.2 m appears to be associated with a clay-rich alteration zone of the Winnipeg Formation. Core above and below this mineralized intercept is currently being assayed. Chris Herald, CEO stated: “We were surprised to intersect this very high-grade silver intercept in GC-012. The mineralized core interval, although clay-altered, was not visually that impressive to host such high-grade mineralization. We are reviewing adjacent core holes to sample potentially similar mineralization. As we await approval of the Ponderosa drilling permit, Solitario is launching a gravity survey that will cover Ponderosa and several other targets at Golden Crest. This work is designed to sharpen our understanding of the geologic architecture of the district and prioritize the most compelling drill targets as we prepare to resume drilling with two core rigs. Ponderosa continues to demonstrate the strongest and largest surface gold mineralization on the property, and our well-positioned drill sites provide an exceptional opportunity to unlock the potential of these exciting new target areas.” With the seven holes completed during the 2025 summer field season, a total of 18 holes have now been drilled on the Golden Crest property. Seven of the first 15 holes intersected significant mineralization. Most of the drilling was widespread, mainly over the western portion of the property. Assays are pending for the final three holes. Besides the high-grade silver intercept in GC-012; GC-012X and GC-013 had multiple intervals in excess of 30 ppb gold, grading up to 0.57 g/t Gold, with highly elevated pathfinder elements, indicating that gold deposition was active throughout most of the western portion of the property.
