Solitario announces Golden Crest metallurgical results

Solitario (XPL) Resources has received favorable metallurgical gold recovery test results for its Golden Crest project in South Dakota. Bottle roll metallurgical testing was conducted on twenty mineralized intervals from 2024 drilling. Average gold recoveries were approximately 69% for nine core samples from drill hole GC-003 and 66% for nine samples from hole GC-008. Importantly, mineralized intervals in both drill holes were all well oxidized, with oxidation extending below 362 meters in GC-008, the limit of drilling for that hole. Chris Herald, President and CEO of Solitario, stated: “This initial metallurgical test work is very encouraging. The gold we intersected in the upper limestone rocks and the deeper lower Deadwood formation is very amenable to standard industry extraction methods. We can confidently move forward with our 2025 drilling program knowing that the mineralization we have identified to date appears to be metallurgically similar to the nearby Wharf-Homestake gold district.” GC-003 and GC-008 are considered the most important mineralization intersected in the 2024 drilling program. Bottle roll tests of this type are often considered the minimum recovered values for gold due to the weak strength of the solution and the limited amount of leaching time of just 48 hours. One sample each from holes GC-010 and GC-011 were also tested and displayed lower recoveries of less than 31%. These samples are considered mineralogical outliers compared to all other mineralized intersections in the 2024 drilling program.
