TINKA proVIDES EXPLORATION UPDATE ON HUWAYMIDAN GOLD PROJECT IN SAUDI ARABIA INCLUDING COMPLETION OF 3,400-METRE RC DRILL PROGRAM

Tinka Resources Ltd. has provided an update of the exploration activities at the Huwaymidan gold property in Saudi Arabia. The Huwaymidan property is owned by Midad Al Mona Mining Company, a Saudi Arabian company of which Tinka has a minority (5-per-cent) 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 five kilometres.
• High-grade gold in surface samples -- Selective surface rocks graded up to 30.5 grams per tonne 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 chief executive officer 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 six 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-per-cent-owned Ayawilca zinc-silver project and our early exploration stage Silvia gold-copper project in Peru."

Technical discussion

Exploration completed in 2025

Tinka acquired a minority stake in the Huwaymidan gold property in Saudi Arabia during July, 2025 (see release dated Aug. 19, 2025). The project is located 300 kilometres 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 (approximately 900 million to 550 million years) of the central Arabian Shield. Several large orogenic-style gold deposits are known within the central Arabian Shield, including Maaden's Ar Rjum gold deposit (approximately 3.9 Moz Au in resources) 30 km along trend to the southeast of Huwaymidan, and the Mansourrah-Masarah gold mine (approximately 7.5 Moz Au in resources) about 100 km to the east.

Exploration at the Huwaymidan project (34 square km) 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 down hole depth of 75 metres. Two areas were drill tested on approximately 250-metre-spaced drill lines covering a combined trend of approximately five kilometres.

District-scale orogenic gold target

Gold mineralization along the Huwaymidan gold trend is associated with quartz veining and hydrothermal alteration of andesite volcanic host rocks. Much of the Huwaymidan trend is covered by wind-blown sand on the flat-lying desert terrain. Surface sampling of discontinuous outcrops of quartz veins as well as quartz float samples has defined two gold targets at the Ibriz and Rawasi areas. Both areas were the focus of the initial 3,400-metre RC drilling program:

• Ibriz: two km by 0.4 km area with abundant quartz float grading up to 30.5 g/t gold (refer to Table 1);
• Rawasi: three km by 0.4 km area with outcropping quartz veins with associated silica-hematite-pyrite alteration grading up to 6.4 g/t gold.

Background of Huwaymidan project ownership

The Huwaymidan project covers a licence area of 34 square kilometres in the Mekkah region of central Saudi Arabia, approximately 300 km east of Jeddah. The project was acquired by a mining consortium which included Tinka as principal technical partner in Round 6 exploration licence auction held by the Ministry of Industry and Mineral Resources of Saudi Arabia in November, 2024. The ministry transferred the Huwaymidan concession to Midad Al Mona, a private Saudi company, in July, 2025. Tinka owns a 5-per-cent carried interest in Midad Al Mona while the company's Saudi partner owns 94 per cent. The exploration and administration costs are fully covered by our Saudi partner for the first two years (up to approximately $3.3-million). The company's Saudi partner is a well-respected and financed family owned group with limited experience in mining and exploration. Tinka is responsible for providing technical expertise and exploration leadership, and in overseeing the field programs to be largely undertaken by third party consultants and local personnel. Consulting fees are paid to Tinka technical personnel, at market rates, capped at $250,000 (U.S.) over two years. Following the initial two-year period, Tinka may continue to hold its interest via a renewed consulting agreement or by a funding arrangement.

Note on assaying

Rock chip samples from Huwaymidan were sent to SGS Ankara for analysis for gold fire assay (30 g aliquot) and ICP multielement analysis.
