Mr. Christopher Herald reports

SOLITARIO ADDS BRIGHT ANGEL GOLD - COPPER PROJECT, FURTHER DIVERSIFYING ITS PROPERTY PORTFOLIO

Solitario Resources Corp. has acquired the Bright Angel copper-gold project in Colorado. At Bright Angel, mineralized porphyry stockwork contains significant values of gold and copper, with minor silver values. Mineralization has been traced over an area approximately 750 metres long and up to 600 metres wide. Both gold and copper are trading at all-time highs, with copper being designated as a critical metal by the United States government.

Bright Angel was originally discovered and drilled in the late 1960s by a private party. Anaconda Copper leased the property in 1970 and drilled 11 core holes, maintaining the lease for 10 years. The property has sat idle for the past 50 years until Solitario acquired the rights to earn 100-per-cent interest in the minerals from a private entity in September, 2025.

To date, Solitario has completed a surface reconnaissance rock sampling program and has initiated drill hole permitting. Results of the surface sampling program have been highly encouraging with consistently anomalous to strong values of gold and copper. Solitario has submitted a notice of intent to the U.S. Forest Service to commence an exploration drilling program at Bright Angel and is currently working on submitting a plan of operations.

Chris Herald, president and chief executive officer of Solitario, stated: "With gold and copper prices at all-time highs, we are extremely excited about the potential of our newly acquired Bright Angel gold-copper property. Our geologic evaluation of Bright Angel is that it is an alkaline pipe-like porphyry system characterized by potentially high grades for both gold and copper with deep roots. We are focused on obtaining a drilling permit and testing this exceptional target, hopefully in late 2026.

The importance of this type of gold-copper deposit is now well known, in large part due to Newcrest Mining's (now Newmont) world-class Cadia-Ridgeway copper-gold pipe-like porphyry deposits discovered in the mid-1990s. The Cadia-Ridgeway gold/copper endowment is estimated to be in excess of 20 million ounces of gold and 10 billion pounds of copper. The lateral footprint of alkaline copper/gold pipe-like porphyry systems are rather small, generally limited to several hundred metres in diameter, but often extending to depths greater than 1,000 metres. Another important attribute is that these deposits often occur in clusters.

Chris Herald, president and chief executive officer, will present at the 2026 Metals Investor Forum in Vancouver, B.C., Canada, on Jan. 23 at 5:20 p.m. PT. The in-person live presentation will not be webcast. Mr. Herald plans to present an overview of Solitario's exploration plans for the Golden Crest gold project -- Ponderosa area, Cat Creek molybdenum-rhenium project, Bright Angel copper-gold property, and its Florida Canyon and Lik zinc projects.

History of project

Drilling at Bright Angel began in the late 1960s when its initial owner completed 186 very shallow (about 16 metres) and widely spaced drill holes. Twelve of the more mineralized holes were deepened to depths of up to 200 metres. Two of the holes reportedly intersected significant grades of gold and copper but are not reported here as Solitario is unable to verify the historic drill hole assay results. However, Solitario's surface rock sampling produced gold/copper grades consistent with the grades in the upper 20 metres of the reported historic drill holes. Drilling will be required to confirm drill hole grades reported in the historic files.

Anaconda Copper, formerly one of the largest mining companies in the world, leased the property in 1970 and drilled 11 widely spaced core holes ranging in depth from 270 to 783 metres. Anaconda's exploration program focused upon testing for a classic large-scale mushroom-shaped, calc-alkaline copper porphyry system common in the Arizona and Chilean copper belts. Calc-alkaline copper systems tend to be laterally extensive, often well over 1,000 metres in diameter. These copper systems are generally gold poor.

Anaconda intersected thick sections of 0.1 per cent to 0.3 per cent Cu in six of their core holes but generally did not assay for gold as gold price was fixed at $38 per ounce at that time and its exploration priority was a primary copper resource. Anaconda concluded that the Bright Angel porphyry was not a calc-alkaline porphyry system but continued to hold the lease for 10 years before exiting the mineral exploration business, when the property was dropped.

Solitario surface sampling

During late-fall, Solitario collected 27 select surface grab samples from an area approximately 750 metres by 600 metres. Results are presented in the attached table. This work confirmed widespread gold and copper mineralization in both porphyry intrusive rocks and skarn.

Plans are also under way to conduct a drone magnetic survey and possibly an induced polarization geophysical survey in the upcoming field season.

Sample type, sampling methodology, chain of custody, quality control and assurance

The reported Bright Angel rock assays are all select surface rock grab/float samples and were generally not collected from a bedrock source. However, these samples are thought to be derived from the underlying bedrock in the immediate area. Rock samples are reconnaissance select grab samples that display alteration, usually with silicification and silica-filled fractures plus/minus sulphide and copper mineralization. The significance of these results is limited to determining whether copper, gold or trace elements usually associated with copper and gold, are present within the sampled rocks. These assay results should not be considered as representative of, nor verify economically mineable mineralization.

Samples were analyzed by ALS Laboratories in Reno, Nev., a laboratory accredited in accordance with the standards of ISO 17025:2017. ALS is independent from Solitario. The samples were collected by Solitario geologists and submitted directly to ALS through secure chain of custody protocols or an independent sample preparation laboratory prior to being shipped to ALS. All activities prior to shipment were directly supervised by Solitario geologists. The samples were crushed and pulverized, and sample pulps were analyzed using industry standard fire assay and inductively coupled plasma -- mass spectrometry (ICP-MS) analytical methods.

About Solitario Resources Corp.

Solitario is a natural resource exploration company focused on high-quality Tier 1 gold, copper, zinc and critical metals (molybdenum and rhenium) projects. Solitario's 100-per-cent-owned Golden Crest properties in South Dakota constitute strategic landholdings (31,500 acres) along the western and southwestern extensions of the Homestake-Wharf mining district that has produced approximately 52 million ounces of gold. Golden Crest is scheduled for a major drilling campaign in 2026.

In addition to its Bright Angel and Golden Crest projects, Solitario holds a 100-per-cent interest in the Cat Creek critical minerals project (molybdenum-rhenium) in Colorado. Solitario also has a 50-per-cent joint venture interest (Teck Resources 50 per cent) in the high-grade Lik zinc deposit in Alaska and a 39-per-cent joint venture interest (Nexa Resources 61 per cent) in the high-grade Florida Canyon zinc project in Peru. Both Florida Canyon and Lik represent advanced exploration projects with over $110-million spent collectively on the properties. Solitario is carried to production on its Florida Canyon project through its joint venture arrangement with Nexa.
