Tinka Acquires Minority Stake in Gold Exploration Property in Saudi Arabia

Rhea-AI Summary

Tinka Resources (OTCQB: TKRFF) has acquired a 5% carried interest in Midad Al Mona Mining Company, which holds the Huwaymidan gold exploration property in Saudi Arabia. The 34 km² property, located 300 km east of Jeddah, was secured through a successful Round 6 exploration license auction.

The property shows promising potential with historic trench sampling yielding up to 10 g/t gold over 2.5 metres within a 1 km strike zone. Tinka's Saudi partner will fully fund operations for the first two years, with exploration set to begin in September 2025. The company will provide technical expertise and receive consulting fees capped at US$250K over 2 years.

The project is strategically located near significant gold deposits, including Ar Rjum (~3.9 Moz Au) and Mansourrah-Masarah (~7.5 Moz Au).

Positive

• No upfront funding required from Tinka for first two years of exploration
• Consulting fees of up to US$250K over 2 years for technical services
• Historic sampling shows high-grade gold potential (10 g/t Au over 2.5m)
• Strategic location near major gold deposits (Ar Rjum 3.9 Moz Au, 30km away)
• Property has never been drilled, offering significant exploration potential

Negative

• Minority stake of only 5% in the project
• Funding arrangement beyond initial two years is uncertain
• Property is partially covered by shallow sand, potentially complicating exploration
• Lock-in period prevents share disposal for first two years

Vancouver, British Columbia--(Newsfile Corp. - August 19, 2025) - Tinka Resources Limited (TSXV: TK) (OTCQB: TKRFF) ("Tinka" or the "Company") is pleased to announce that it has acquired, through its 100%-owned subsidiary Tinka Saudi Resources Corp., a minority stake in a mineral exploration property in Saudi Arabia prospective for gold deposits. The concession over the Property, known as "Huwaymidan", was acquired as the result of a successful competitive tender by a mining consortium including Tinka in Round 6 exploration licence auction held by the Ministry of Industry and Mineral Resources of Saudi Arabia (the "Ministry") in November 2024 (link here). The Ministry granted a concession over the Property to Midad Al Mona Mining Company ("Midad Al Mona"), a newly established Saudi Arabian company, in late July 2025. Tinka now owns a 5% carried interest in Midad Al Mona while our Saudi Arabian partner owns 94%. Midad Al Mona will be fully funded and capitalized by our Saudi partner for the first two years of the exploration program.

Huwaymidan covers an area of 34 km² in the Jiddah Terrane of the Saudi Arabian Shield (Figure 1). Numerous gold workings are known, while no mineral resources have been defined. Past trench sampling results include 10 g/t gold over 2.5 metres within a much wider clay - silica alteration zone with gold anomalism and a mapped strike of 1 km. Field work will commence in September 2025 with a program of mapping, rock sampling and ground-based geophysics (magnetics). An initial shallow drill program is planned for late 2025, and no additional permitting is required to allow drilling.

Key highlights of the Huwaymidan Property acquisition:

• Huwaymidan is situated 300 km east of the Red Sea city of Jeddah in central Saudi Arabia, an area with excellent road access.
• The Property has historic gold workings (surface trench results up to 2.5 m @ 10 g/t Au) yet to be tested by modern exploration. There is no past drilling recorded. Much of the area is covered by shallow sand.
• The Property is located in an underexplored region of the Precambrian-age Arabian Shield prospective for orogenic gold. Deposits in the region include Ar Rjum (~ 3.9 Moz Au) just 30 km from Huwaymidan, and Mansourrah-Masarah gold mines (~ 7.5 Moz Au) operated by Maaden approximately 100 km from the Property (Figure 1);
• Midad Al Mona will be funded and capitalized by Kalimat Al Hikma our Saudi partner, a private company, to undertake the anticipated exploration programs in 2025 and 2026.
• Tinka will provide exploration expertise and technical leadership to Midad Al Mona and be paid consulting fees for all services provided;
• Tinka holds a 5% carried interest for the first two years. Afterwards, Tinka may continue to hold its interest by negotiating a renewed consulting agreement or via a funding arrangement.

Dr. Graham Carman, Tinka's President and CEO, stated: "This new venture in Saudi Arabia is an exciting opportunity for our Company. Our Saudi partner is a well funded and well-respected family-run company based out of Jeddah. The project company will be funded and capitalized by our Saudi partner for at least the first two years, with Tinka providing exploration leadership and project oversight. Not only is there no upfront funding required by Tinka but we will be paid for all services provided."

Dr. Carman continued: "Tinka gains critical access through this relationship to exploration and capital market opportunities in the Middle East. This is a huge capital market, which has started to diversify investments from hydrocarbon industries into new opportunities including in the mining sector. Importantly, the Saudi venture will not detract from our focus in Peru. On-ground activities in Saudi will largely be supervised by 3^rd party geological consultants and locally sourced personnel."

The Huwaymidan Gold Property

Background

Huwaymidan was awarded to the Midad Al Mona - Tinka consortium on November 24, 2024, following a competitive tender process under exploration licencing Round 6 by the Saudi government (link here). A concession over the Property was granted to Midad Al Mona in late July 2025 covering 34 km². The ownership of Midad Al Mona is: Kalimat Al Hikma 94% (a local company), Tinka Saudi Resources Corp. 5% and Orthosa Pty. Ltd. 1% (a private Australian exploration consulting company not related to Tinka). Tinka is responsible for providing technical expertise and exploration leadership to Midad Al Mona, and in overseeing the field program to be largely undertaken by 3^rd party consultants and local personnel. The Saudi partner will cover sufficient funding and capitalization for the first 2 years.

Geology

Huwaymidan is located 300 km east of Jeddah in the Jiddah Terrane (Figure 1). The Property is prospective for orogenic gold deposits hosted by Precambrian mafic volcanic and intrusive igneous rocks associated with shear zones. Past exploration data is limited to surface sampling for gold associated with old workings. Geochemical data from historic trenches returned results up to 2.5 m grading 10 g/t gold within a zone of hydrothermal clay-silica alteration with iron oxides up to 200 metres wide and 1 km in strike length (NW-SE). A reconnaissance field trip in January 2025 confirmed this zone of alteration in trench debris (with trenches largely infilled with recent sand) with check samples grading up to 6 g/t Au.

Regionally, the Arabian Shield is composed of Proterozoic (~900-550 million year old) igneous and sedimentary rocks. Several large gold deposits are currently in operation within the Arabian Shield in Saudi Arabia and the Nubian Shield across the Red Sea in Egypt (including the world-class Sukari mine >10 Moz gold) - see Figure 1. The Huwaymidan Property lies within the Ash Shakhtaliyat belt consisting mostly of mafic volcanics and intrusive rocks. The Ar Rjum gold deposit (3.9 Moz Au) lies within the same belt 30 km to the southeast of the Property. Mansourrah-Masarah gold mines (~ 7.5 Moz Au) are located approximately 100 km to the east. Gold mineralization in these deposits is generally associated with shear zones and quartz veining hosted either in volcanic or intrusive rocks. The Jabal Sayid copper mine is a volcanogenic massive sulphide deposit approximately 150 km to the NNW of the Property.

Key Deal Terms

• Tinka to have 5% carried ownership of Midad Al Mona for the first two years;
• Exploration to focus on the Huwaymidan Property for gold. All exploration and administration costs to be covered by our Saudi partner for the first two years (up to ~C$2.3 M);
• Tinka to provide exploration leadership to Midad Al Mona with Dr. Graham Carman as Technical Director;
• Consulting fees to be paid to Tinka technical personnel, at market rates, capped at US$250K over 2 years;
• Certain KPIs to be met by Tinka during the first two years in order to retain an interest in Huwaymidan, including the successful execution of a drill program;
• Following the initial two-year period, Tinka may continue to hold its interest via a renewed consulting agreement or by a funding arrangement;
• All shareholders to be locked-in for the first two years, a period when shareholders are unable to sell, transfer, or otherwise dispose of its shares or their interest in Midad Al Mona.
