DENVER, CO / ACCESSWIRE / March 28, 2024 / Solitario Resources Corp. ("Solitario") (NYSE American:XPL)(TSX:SLR) is pleased to report that it has discovered another high-grade gold zone on its Golden Crest project, named Sleeping Beauty. 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 39.6, 24.6 and 16.6 grams per tonne ("gpt") gold.

Sleeping Beauty is situated on a topographic plateau underlain by the same favorable limestone found at the high-grade Geyer gold zone, which is located about 500 meters to the south. The two zones are separated by a shallow valley, where mineralization is considerably weaker at surface and rock outcrops are absent. Although the Sleeping Beauty zone has an apparent east-west orientation, the overall trend of mineralization over a larger scale area is thought to be generally in a northeast-southwest direction.

Approximately 135 samples were collected and assayed from the Sleeping Beauty topographic plateau area (see map). Twenty-eight of these samples assayed greater than 1.0 gpt gold, with 65 samples greater than 0.2 gpt gold. Within the 1600-meter-long trend, there are five clusters of higher-grade gold. The highest-grade cluster measures 170 by 260 meters and is open in all directions. The average grade of all 14 grab samples collected in this high-grade cluster is 7.12 gpt gold.

Table 1 presents the 12 highest-grade rock grab samples in the Sleeping Beauty topographic plateau.

Chris Herald, President and CEO of Solitario, stated: "In the late summer of 2023 we began to focus on a large area north of Geyser, as the north side of Geyser was open to expansion. This area, that we now call Sleeping Beauty, has developed into one of the largest target areas yet discovered at Golden Crest. Although sampling is still in the early days at Sleeping Beauty, we believe that it will develop into a major high-grade target area with the additional work we have planned for 2024. Importantly, we anticipate reporting our final assay results from the 2023 field season over the next several weeks."

Golden Crest Drill Hole Permitting and Project Overview

The Sleeping Beauty and Geyser gold zones are located on Solitario's new Ponderosa Plan of Operations (POO) 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 Sleeping Beauty rock samples 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.

Forward-looking statements involve numerous risks and uncertainties. Consequently, there can be no assurances that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Solitario's Golden Crest land position does not cover any of the areas of historical gold production or historical unmined resources. Certain historical information concerning exploration and gold production in the Black Hills region has been obtained through both public and private sources and are believed to be substantially factual, but Solitario can give no assurances of the accuracy of such information. The existence of historic mines and resources adjacent to Solitario's land position do not necessarily support the existence economic mineral deposits on Solitario's land position. Such forward-looking statements include, without limitation, statements regarding the Company's expectation of the projected timing and outcome of engineering studies; expectations regarding the receipt of all necessary permits and approvals to implement a mining plan, if any, at any of its mineral properties. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, among others, risks relating to risks that Solitario's and its joint venture partners' exploration and property advancement efforts will not be successful; risks relating to fluctuations in the price of zinc, gold, lead and silver; the inherently hazardous nature of mining-related activities; uncertainties concerning reserve and resource estimates; availability of outside contractors, and other activities; uncertainties relating to obtaining approvals and permits from governmental regulatory authorities; the possibility that environmental laws and regulations will change over time and become even more restrictive; and availability and timing of capital for financing the Company's exploration and development activities, including uncertainty of being able to raise capital on favorable terms or at all; risks relating to the impacts of Covid-19 or similar variants; as well as those factors discussed in Solitario's filings with the U.S. Securities and Exchange Commission (the "SEC") including Solitario's latest Annual Report on Form 10-K and its other SEC filings (and Canadian filings) including, without limitation, its latest Quarterly Report on Form 10-Q.
