Solitario Resources Discovers Gold in First Three Golden Crest Drill Holes

• 26.4 Meters Averaging 2.6 g/t Gold; including 14.4 Meters at 4.2 g/t

• 32.0 Meters Averaging 1.7 g/t Gold; including 14.2 Meters at 3.1 g/t

DENVER, CO / ACCESSWIRE / September 16, 2024 / Solitario Resources Corp. ("Solitario") (NYSE:XPL)(TSX:SLR) is pleased to announce the results of the first three core holes ever drilled on its Golden Crest Project. All three holes intersected significant thicknesses of mineralization, with two of the holes displaying high-grade intercepts. Cross sections of the three holes can be viewed here. This zone, although currently limited in size due to the lack of offset drilling, is laterally open in all directions. Highlights include:

DDH Hole	Interval	Thickness	Grade
Number	(meters)	(meters)	(grams/tonne)
GC-001	9.1 to 41.1	32.0	1.68
including	10.7 to 24.9	14.2	3.10
GC-002	7.9 to 17.8	9.9	0.72
	23.3 to 33.2	9.9	1.88
	40.2 to 46.3	6.1	0.55
GC-003	5.0 to 31.4	26.4	2.56
including	11.4 to 25.8	14.4	4.18
including	19.8 to 21.8	2.0	13.13
	38.9 to 50.6	11.7	0.60
Estimated true thickness of reported intervals: GC-001: 75% +/-10%; GC-002: 90% +/-10%; GC-003: 90% +/-10%

Chris Herald, President and CEO of Solitario, stated: "These core holes represent a true new gold discovery that are potentially part of a major new district-scale extension of the Homestake-Wharf super giant gold district. Considering that these are the first holes ever drilled on our huge 35,000-acre property, they are truly outstanding. Significant gold mineralization over substantial widths with excellent continuity was intersected in all three holes. Importantly, these results also confirm that the multiple high-quality surface anomalies we have generated during the past three years have the potential to have sizable subsurface roots in both grade and size.

We also firmly believe the best is yet to come. This year's program is only testing two of our ten best high-potential target areas. The other eight are still undergoing various stages of permitting with drilling planned on four more in 2025. We are also encouraged that other potential gold horizons below the mineralized Downpour zone are returning anomalous gold and trace element values.. With additional drilling, we will have the ability to vector into significant mineralization in structures and multiple stratigraphic horizons that have been very productive in the historic Homestake-Wharf mining district. All mineralization encountered to date is oxidized."

What Do These Results Mean and Drilling Details

Gold mineralization at Downpour occurs within an intensely brecciated evaporite stratigraphic horizon that has undergone significant silicification and hydrothermal alteration. This favorable zone is sub-horizontal and appears to occur throughout Solitario's land position. Solitario has identified a number of other high-priority prospects in this favorable horizon. Besides the excellent grade and thickness of mineralization encountered in drilling, the potential for high-grade feeder structures is considered excellent.

All three core holes were drilled at the Downpour prospect from the same platform near exceptional gold assay results in trenches (previously reported). Total meterage for the first three holes is 963.5 meters. We expect drilling to continue well into November. Remaining drilling consists of widely spaced holes over Solitario's vast 35,000-acre land holding. We are on track to complete about a dozen core holes totaling up to 5,000 meters.

Golden Crest Future Drill Hole Plans

Solitario has identified ten high priority surface targets as shown in the table below. Two of the targets, Downpour and Eleventh Hour, will be drilled this year. Four new targets are currently being permitted and are scheduled to be drilled in 2025. The other four high-priority targets may undergo future permitting after further review. Besides the ten currently defined high-priority targets, Solitario has identified another dozen promising target areas that require additional surface exploration work. Three years of concentrated exploration surface work has defined approximately 80-square kilometers of gold bearing hydrothermal alteration.

Permitting Still at Early Stage for Priority Targets

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 and not on Solitario's property). 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

All Golden Crest exploration core samples have been prepared and analyzed at the American Assay Laboratories in Reno, Nevada, which is independent from Solitario. Thorough QA/QC protocols are followed on the Project, including insertion of duplicate, blank and standard samples in the assay stream for all drill holes. The samples are collected directly from the drill rig, logged, photographed, split into two samples, and half of each sample submitted directly to American Assay Labs through secure chain of custody protocols. All activities prior to shipment are directly supervised by Solitario geologists. Samples are pulverized from a 250g sample to 85% passing 75 mesh. Approximately 225g of pulp sample is used for fire assay. Assays are based on a 30g fire assay aliquot for gold with Atomic Absorption finish. If the gold value from Atomic Absorption is >10g/t, an additional 30g of pulp sample is fire assayed for gold using a gravimetric finish.

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.
