08:37 AM EDT, 03/18/2024 (MT Newswires) -- Solitario Resources Corp. ( XPL ) reported Monday that it has "significantly expanded, and better defined through infill rock sampling", the Geyser gold zone area on its Golden Crest project.

Acccording to a statement, recently received assay results from reconnaissance rock sampling of outcrop, sub-crop and float from the 2023 field season yielded gold values as high as 171.5, 108.0, 78.6 and 59.9 grams per tonne gold.

Solitario noted Geyser was previously reported as three separate zones: Geyser, Spur and Zig Zag. Results from the 2023 reconnaissance rock grab sampling program resulted in these three zones coalescing into a single zone that is now solely referred to as the Geyser Zone. The complete Geyser dataset from the 2022 and 2023 field seasons totals 515 rock grab samples. Ninety-nine (99) of these samples have returned values in excess of 1.0 gpt gold, with 36 exceeding 10 gpt gold.

Chris Herald, President and CEO of Solitario, in Monday's statement said: "We believe Geyser has developed into one of the most exciting greenfields gold exploration targets in North America. Mineralization defined to date at Geyser displays a widespread distribution of very high-grade gold in surface samples, within an overall halo of lower-grade gold. We remain amazed at the strength of this 80-square kilometer hydrothermal gold system, and the fact that it remained undiscovered throughout the 150-year history of exploration and mining in the northern Black Hills.

"We are confident that with continued surface exploration, this strongly mineralized area will continue to expand. We are still receiving assay results for rocks collected during 2023 and anticipate releasing additional results in the next several weeks."
