SULLIDEN ACQUIRES PORTION OF NICKEL, ZINC, AND LEAD MINING EXPLORATION PROJECT IN POLAND

Sulliden Mining Capital Inc. has indirectly acquired a 5.2-per-cent interest in a nickel, zinc and lead mining exploration project in Poland through the purchase of 10 per cent of the issued and outstanding shares of Sustainable Royalty Corp., a private company, from Stan Bharti, a former chief executive officer and director of the company. The project consists of the Szklary and Dabrowka concessions, each as described in greater detail below.

Pursuant to a share purchase agreement respecting the acquisition dated April 3, 2025, Sulliden acquired a 10-per-cent equity interest in the target (or one million of the target's issued and outstanding common shares), with Mr. Bharti retaining a 63-per-cent interest. The target owns 52 per cent of Ferrite Resources Polska sp. Z.o.o., a company incorporated in Poland, which owns 100 per cent of the Szklary and Dabrowka concessions. As consideration, Sulliden paid an aggregate of C$100,000 to the vendor and committed to spending an additional 250,000 euros on the project within six months of closing. The acquisition was an arm's-length transaction for purposes of the policies of the Toronto Stock Exchange. No finders' fees were paid in connection with, and no change of control of Sulliden resulted from, the acquisition.

Szklary is a nickel laterite deposit located approximately 50 kilometres (km) south of Wroclaw, Poland. The deposit forms north-south-striking elongated ridge with the nickel (Ni) laterite exposed in the first 20 metres (m) below surface. Historical production is recorded as 3.5 million tonnes at 0.79 per cent Ni equal to 28,000 tonnes. Approximately 2,500 holes were drilled in the past during the Soviet era and a technical report was previously prepared that is compliant with National Instrument 43-101, Standards of Disclosure for Mineral Projects, for the central part of the property (Redstone Exploration Service, February, 2022). However, because of the absence of drill core, the company expects that an extra 30 holes will be drilled to confirm the historical inferred mineral resource described in the report. Mining would skim the laterite and continuing exploration is expected by the company to investigate the as yet unexplored sulphite deposit at depth. Szklary has a JORC-compliant historical inferred mineral resource of 32.9 million tonnes at 0.70 per cent Ni (Northern Mining Ltd., filed with the Australian Securities Exchange in July, 2008).

Dabrowka is located 25 km north of the city of Katowice, Poland. The property has an existing mined out shaft but requires a small decline shaft to a maximum of 80 m depth. As a result, the company anticipates that little primary development is necessary. The in situ historical non-compliant inferred mineral resource (M. O'Brien, February, 2024) has been estimated as an in situ JORC-compliant resource as follows:

• Zinc -- 22.4 million tonnes at 2.8 per cent equal to 634,940 tonnes;
• Lead -- 22.4 million tonnes at 0.7 per cent equal to 154,000 tonnes.

The company expects that an additional 27 holes will be drilled to compliment the historical exploration.

Note that a qualified person (as such term is defined in National Instrument 43-101) has not done sufficient work to classify the historical estimates described above as current mineral resources or mineral reserves, and the company is not treating the historical estimate as current mineral resources or mineral reserves.

Upside benefits of the project:

• Two smelters are situated less than 20 km away from the project, which are accessible via rail;
• Room and pillar mining methods, using decline, are utilized at the project -- magnetic separation of ore is proven technology currently used in several mines;
• There is a potential second Zn-Pb (zinc-lead) deposit at between 80 and 100 m apart from primary at four to 50 m depth.

Fred Leigh, chief executive officer of Sulliden, commented: "We are pleased to announce our strategic investment in a Polish mining asset, reinforcing our commitment to expanding our portfolio in key resource sectors."
