American Marconi Wireless News - Solitario Resources Intersects 11.55 and 2.45 g/t Gold in Two Important New Styles of Gold Mineralization at Golden Crest

DENVER, CO / ACCESS Newswire / February 6, 2025 / Solitario Resources Corp. ("Solitario") (NYSE American:XPL)(TSX:SLR) is pleased to announce important new drilling results on its Golden Crest Project. Two distinctly different styles and ages of gold mineralization were encountered in drill hole GC-010. The lower interval in GC-010 intersected 11.55 grams per tonne ("g/t") gold over 0.52 meters. This high-grade interval represents paleo-placer gold mineralization (see definition below) positioned between older Precambrian and younger Paleozoic-aged rock formations (Lower Deadwood). The importance of this newly discovered style of gold mineralization is that it supports the existence of Homestake-style Precambrian-aged mineralization in the vicinity of this intercept.

The second mineralized interval in GC-010 occurred several meters above the paleo-placer interval. It graded 2.45 g/t gold over 0.43 meters and consisted of rock flour diatreme breccia that is not pyritized or silicified. The gold grade is thought to be carried by small, pulverized matrix fragments from the Precambrian basement that were forcefully injected into the Lower Deadwood Formation. This also suggests the potential for significant basement-hosted mineralization nearby within our claim block.

Precambrian Homestake Banded Iron Formation ("BIF") was intersected in both GC-009 and GC-010. This is the only area outside of the immediate Homestake district that Homestake BIF has been identified. The Homestake BIF hosts the entire 68-million-ounce gold endowment of the Homestake mine situated about 15 kilometers east of these drill holes.

Chris Herald, President and CEO of Solitario, stated: "We always thought that we would intersect a variety of styles of Tertiary-aged mineralization at Golden Crest, but the paleo-placer intercept was a big surprise. We believe the only way this high-grade paleo-placer could have formed was the existence of a Homestake-style Precambrian deposit situated relatively near GC-010 during Cambrian times that was eroded and formed this paleo-placer gold deposit. This opens up a whole new mega-gold target at Golden Crest, but perhaps more importantly, it gives us a tool to vector in on a Homestake target. In the historic Homestake district, moderate to high-grade gold mineralization spread out over approximately ten square kilometers in a laterally distributed alluvial fan. The grade and thickness of gold mineralization increased the closer you were to the actual Precambrian deposit, which was the origin for the gold in this type of deposit.

Paleo-placer gold mineralization represented an important gold source during the early Homestake production. Historic records estimate approximately 1.2 million ounces of high-grade gold were produced, and another 10 million ounces is believed to have been eroded from the Homestake ledges prior to the deposition of the Lower Deadwood Formation. When you consider the high-grade paleo-placer intercept, the well mineralized diatreme breccia, and the occurrence of rare Homestake BIF in the area, these are the ingredients that point towards the presence of significant Homestake-style mineralization on our Golden Crest property - truly fertile exploration terrain that we are excited to begin drill testing later this year."

*¹- True thickness cannot be estimated based on this single drill hole; Azimuth 208°; Dip 75°

*² - Paleo-placer gold deposits are formed and transported by water processes that occurred millions of years ago and were then covered by younger rocks. These deposits are typically ancient riverbeds, beaches, or slopes. The Homestake paleo-placer is considered an ancient alluvial placer.

2024 Drilling Program Review
Solitario completed 11 core holes on the Golden Crest property totaling 4,345.7 meters in 2024. Assay results for the first ten holes have been received and released. Results for GC-11 are expected to be released within two weeks. Core holes GC-001 to GC-003 were well mineralized and previously reported (see News Release dated September 16, 2024). Significant mineralization was intersected in the Lower Deadwood Formation in hole GC-008 (see News Release dated December 9, 2024). GC-004 through GC-007, and GC-009, showed anomalous gold and/or pathfinder element values in the Paleozoic sedimentary rock formations and demonstrates that gold-bearing hydrothermal fluids have significantly altered the carbonate and clastic formations over a vertical extent of up to 400 meters and laterally an area of 80-square kilometers at surface. We believe with further drilling we can vector into zones hosting potentially economic mineralization.

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, were drilled in 2024. 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 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. Furthermore, Solitario's future drilling has the potential to intersect the highly prolific Homestake Formation, situated below the Lower Deadwood formation.

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 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. Core is placed and marked in boxes and then 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.
