Solitario Resources Corp. announced that it has significantly expanded, and better defined through infill rock sampling, the Geyser gold zone area on its Golden Crest project. 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 ("gpt") gold.

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. The Geyser Zone is V-shaped and is believed to represent two intersecting structural trends. The west limb is a broad rectilinear zone that trends north-south and is 1,200 meter long and up to 600 meters wide.

At its southern end, a distinct, structurally controlled zone branches off to the northeast for 1,100 meters forming the eastern limb of the V-shaped surface mineralization. This zone varies from 200 to 400 meters in width. A third, less-well defined subzone exists east of this structure.

The two primary limbs to the Geyser prospect are characterized by scattered, but widespread, high-grade gold values surrounded by large zones of lower-grade mineralization between 0.2 to 2.0 gpt gold. Previously reported Spur Trench 1 results, 0.82 gpt gold over a continuously sampled 234-meter trench in bedrock and sub-crop, exemplifies this lower-grade halo. Golden Crest Drill Hole Permitting and Project Overview: The Geyser gold zone is located on Solitario's new Ponderosa Plan of Operations (POO) which is located in the easternmost portion of Solitario's consolidated Golden Crest property.

The Ponderosa area is a non-contiguous group of mineral claims not covered by the original Golden Crest POO, but is a part of Solitario's 100%-owned Golden Crest project area in South Dakota. The new Ponderosa POO proposes low-impact core drilling to test the Geyser gold zone and several other new gold targets. In December 2023, the United States Forest Service ("USFS") issued its final Environmental Assessment ("EA") and Draft Decision and Finding of No Significant Impact (FONSI) on Solitario's proposed Golden Crest drilling program.

As a result of this decision, no additional environmental studies beyond USFS's comprehensive EA is required. Currently, the USFS is finalizing its response to objections to their FONSI decision. Solitario's 100%-owned Golden Crest properties in South Dakota constitute strategic land holdings along the western and southwestern extensions of the Homestake-Wharf mining district that has produced approximately 52 million ounces of gold and contains another 30 million ounces in historical resources (not SK-1300 or NI-4301 compliant).

The project area is in a safe jurisdiction with highly developed infrastructure, an unbroken 150-year record of continuous gold mining, a skilled mining workforce, and a history of high-grade, underground mineable gold deposits. Sample Type, Sampling Methodology, Chain of Custody, Quality Control and Assurance: The reported Geyser rock assays are all surface rock grab/float samples consisting of near-bedrock float samples, and to a lesser extent, bedrock and sub-crop composite grab samples. All float samples are thought to be derived from the underlying bedrock within the immediate sampled area.

All sampling reported in this release was supervised by project geologists, including chain of custody. Rock samples are reconnaissance select grab samples that display alteration, usually silicification and hydrothermal brecciation. The significance of these results is limited to determining whether gold, or trace elements usually associated with gold, are present within rocks affected by hydrothermal alteration fluids.

Assay results may not be representative of, nor verify economically mineable mineralization. Samples were analyzed by ALS Laboratories in Reno, NV, a laboratory accredited in accordance with the standards of ISO 17025:2017. The samples were crushed and pulverized, and sample pulps were analyzed using industry standard fire assay methods.

A certified reference sample or duplicate was inserted at least every 20th sample.
