Heraldo de Madrid - Solitario Resources Completes Highly Successful 2024 Drilling Campaign

In the nearby historic Homestake-Wharf mining camp, with an overall gold endowment*¹ approaching 95 million ounces, there are six geologic environments in which gold was deposited. Drilling at Golden Crest intersected significant gold values in four of these deposit types, and strong indirect evidence that the fifth and sixth deposit types are present (see table below and schematic cross section here).

Chris Herald, President and CEO of Solitario, stated: "This year's results surpassed our highest expectations. Solitario's multiple new greenfield discoveries have opened-up significant targets that are wide-open to expansion. As these sites are already permitted, we plan to offset these mineralized drill holes beginning in late-May. Priority areas for expansion include the Downpour zone where near-surface mineralization was intersected in all three drill holes, each averaging about 30 meters of 1.7 g/t gold; Lands End - GC-008 that intersected 41 meters at approximately 1.0 g/t in the lower Deadwood Formation; and GC-010, that intersected 11.33 g/t gold over 0.52 meters in a paleo-placer on top of the Precambrian Homestake Formation and 2.45 g/t gold over 0.43 meters in a Tertiary igneous breccia.

We are equally excited to initiate the first ever drilling in the Ponderosa area situated immediately southeast of our Golden Crest claim block. Our strongest and most widespread surface gold anomalies occur within the Ponderosa permit application and include the Geyser, Sleeping Beauty, Holland, Wild Cat and Moonlight target zones. We anticipate utilizing a second drill rig at Ponderosa and are targeting a mid-summer start date. Forty-five (45) drilling platforms are included in the Ponderosa Plan of Operations to drill test these strong surface gold anomalies (here)."

Hole GC-011: Eleventh Hour
The last drill hole of the season, GC-011, was the furthest north drill hole in an area referred to as the Eleventh Hour zone. Strong gold mineralization was intersected within massive limestone of the Lodgepole Formation. The mineralization is thought to be situated within a feeder structure.

• GC-011: 2.68 meters @ 4.69 g/t gold starting at 161.9 meters

Drilling Statistics
Solitario completed 11 core holes in 2024 on the Golden Crest property (see drill hole location map here) totaling 4,345.7 meters. Assay results for all drill holes have now been received.

Core holes GC-001 to GC-003 intersected silicified and well mineralized evaporite collapse breccias in the Mississippian-aged Mission Canyon limestone (see News Release dated September 16, 2024). GC-004 through GC-007 showed anomalous gold and/or trace element values in the Paleozoic sedimentary rock formations, while hole GC-008 intersected a wide interval of well mineralized Lower Deadwood Formation (see news release dated December 9, 2024) indicating the potential for significant Wharf-style mineralization. GC-009 and GC-010 both intersected Precambrian Homestake Formation, the only known occurrence of this rock unit outside of the Homestake district. Additionally, GC-010 intersected high-grade paleo-placer gold between the Homestake Formation and much younger Lower Deadwood Formation, as well as mineralized diatreme intrusive breccia (see news release dated February 6, 2025). Drill hole GC-011 intersected a mineralized near-vertical structure in Paleozoic limestones.

Abundance of High-Quality Drilling Targets
Solitario has identified ten high priority surface targets (including the Ponderosa area) as shown in the table below. Two of the targets, Downpour and Eleventh Hour, were drilled this year. Five new targets are currently being permitted and are scheduled to be drilled in 2025. The other three high-priority targets may undergo future permitting following further review. In addition to the ten currently defined high-priority targets, Solitario has identified another dozen promising target areas that require additional surface exploration work. Solitario's future drilling will not only test the strong surface gold anomalies, but the underlying and highly prolific Lower Deadwood Formation, paleo-placer and Homestake banded iron formation mineralization.

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 35 million ounces in resources and historical resources (not SK-1300 or NI43-101 compliant and not located 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 prepared 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.
