Tinka Provides Exploration Update on Huwaymidan Gold Project in Saudi Arabia Including Completion of 3,400-Metre RC Drill ProgramVancouver, British Columbia--(Newsfile Corp. - January 12, 2026) - Tinka Resources Limited (TSXV: TK) (OTCQB: TKRFF) ("Tinka" or the "Company") is pleased to provide an update of the exploration activities at the Huwaymidan gold property in Saudi Arabia. The Huwaymidan property ("Huwaymidan" or the "Project") is owned by Midad Al Mona Mining Company ("Midad"), a Saudi Arabian company of which Tinka has a minority (5%) equity ownership. Tinka has a free-carried interest until mid 2027 and is responsible for providing technical expertise and exploration leadership to the Project. Exploration on the ground is largely carried out by third-party consultants and local contractors. Key highlights:Reconnaissance 3,400 metre drill program completed at Huwaymidan – A 46-hole reverse circulation (RC) drill program was carried out in December 2025. The drill rigs have now demobilized, with assay results pending. District-scale orogenic gold potential – The initial drill program targeted gold mineralization identified by selective surface sampling at two target areas covering a potential gold trend of more than 5 kilometres. High-grade gold in surface samples – Selective surface rocks graded up to 30.5 g/t gold in quartz float and up to 6.4 g/t gold in outcropping quartz veins. Refer to technical discussion for more details of rock sample results. Significant zones of quartz veining and widespread hydrothermal alteration – Drilling intersected wide zones of pervasive hydrothermal alteration and quartz veining, features consistent with a large orogenic gold system. Note that no gold assays are available at this time. Next steps – Assay results from the drilling are expected late Q1 2026. Subject to results, a follow-up drill program is planned for Q2 2026. Cautionary note: by their nature, surface samples represent selective samples and do not necessarily reflect the overall grade of underlying mineralization.Dr. Graham Carman, President and CEO of Tinka, stated: "The exploration program at Huwaymidan is advancing very well, with encouraging surface results for gold and the completion of an initial 3,400 metre RC drill program within 6 months of acquiring an interest in the property, thanks to the support of our local partner and our consultants. Huwaymidan is located in a proven gold belt just 30 kilometres along trend of Maaden's Ar Rjum project (3.9 Moz gold) and we believe Huwaymidan has the potential to be a district-scale gold target. The aim of the reconnaissance drill program was to drill test the most obvious surface gold occurrences on a wide-spaced drilling grid. We look forward to receiving gold assays soon, so that the most promising areas for gold can be quickly followed up with additional work including more focused drilling.""The exploration programs at Huwaymidan are fully-funded by our local Saudi partner until mid 2027. The main focus of Tinka's exploration remains our 100% owned Ayawilca zinc-silver project, and our early exploration stage Silvia gold-copper project in Peru."Technical DiscussionExploration completed in 2025Tinka acquired a minority stake in the Huwaymidan gold property in Saudi Arabia during July 2025 (see release dated August 19, 2025). The Project is located 300 km east of Jeddah and is close to excellent infrastructure including a major highway and large town. The geology consists mostly of mafic volcanics and intrusions of Proterozoic age (~900–550 million years) of the central Arabian Shield (Figure 1). Several large orogenic-style gold deposits are known within the central Arabian Shield, including Maaden's Ar Rjum gold deposit (~3.9 Moz Au in resources) 30 km along trend to the southeast of Huwaymidan, and the Mansourrah-Masarah gold mine (~7.5 Moz Au in resources) some 100 km to the east. Exploration at the Huwaymidan Project (34 km2) has progressed significantly during the second half of 2025. Systematic geological mapping and sampling was conducted in September and October with more than 500 rock samples assayed for gold and pathfinder elements. A 340 line-kilometre ground magnetic survey was acquired over the entire property in October 2025. The results of this exploration have identified a 10-kilometre gold trend exposed discontinuously throughout the Huwaymidan property, believed to be associated with a large district-scale orogenic-type gold system. A reconnaissance RC drilling program commenced in late November 2025 and was completed by the end of December 2025. The drill program was designed to follow-up on encouraging gold assays from surface sampling. In total, 46 holes for 3,436 metres were drilled with two rigs operating. All holes were drilled at an angle of between 50 and 60 degrees on a grid pattern, to an average downhole depth of 75 metres. Two areas were drill tested on ~250 metre-spaced drill lines covering a combined trend of appr
