Centurion Executes Option Agreement for Limestone Gold Project, near Zijin’s Rosebel Gold Mine in Suriname

Vancouver, British Columbia–(Newsfile Corp. – March 26, 2026) – CENTURION MINERALS LTD. (TSXV: CTN) (“Centurion” or the “Company“) is pleased to announce it has executed an Option to Purchase Agreement (the “Agreement“) for the Limestone gold project (“Limestone” or the “Project“) in Suriname. The Project is located proximal to the Rosebel and Saramacca Mines of Zijin Mining Group Co., Ltd. (“Zijin“) (see Figure 1), and areas of extensive small-scale mining (see Figure 4).

The 3,548-hectare Project is well situated for a gold discovery (see Figure 1 below). Historic and active small-scale mining indicates the presence of gold within the Limestone concession. Limestone is situated in the largest and most productive region of both active and historic gold mining in Suriname. This region includes the Rosebel Gold mines operated by Zijin hosting a resource exceeding 6 million ounces of gold (195 tonnes) with a grade of 1.04 g/t (Source: Zijin, Rosebel Mine). In addition, other international mining companies have been active in the region, exploring and drilling projects along the Saramacca and Rosebel Mine trends of Zijin. Limestone appears to be along the Saramacca mine trend.

The Limestone gold project maintains an exploitation license granted to the current concession holders (the “Optionors“) in 2025. The Project is less than 4 hours by road (or boat) from Paramaribo, Suriname’s capital city, with the Saramacca River crossing the concession area.

Gold mineralization in Suriname is primarily controlled by structural and lithological factors within the Paleoproterozoic Marowijne Greenstone Belt of the prolific gold producing Guiana Shield (Source: Journal of South American Earth Sciences). The deposits are predominantly classified as orogenic gold systems formed during the Trans-Amazonian orogeny (Source: Cambridge University Press) (see Figure 3).

Suriname has two tier one mines, Rosebel owned by Zijin and Merian owned by Newmont Corp. (“Newmont“), both located within the greenstone belt. Historically, the greenstone belt has been underexplored, however, in recent years the area has experienced a surge in mineral exploration activity from companies including Founders Metals Inc., Miata Metals Corp., Greenheart Gold Inc., and Sranan Gold Corp. Suriname has the potential to develop multiple new mines from concessions having similar potential to Limestone.

Addition of Suriname-Based Exploration and Development Team
The Company intends to conduct exploration utilizing an experienced Suriname-based team located in Paramaribo. The exploration and development team is supervised by Dr. Dennis LaPoint, Ph.D., P.Geo, having more than 26 years’ experience in Suriname. Dr. LaPoint led the geological team’s discovery of what has become the Merian Mine, currently owned by Newmont.

Strategic Focus on Exploration and Mining Jurisdictions:
Centurion’s Suriname objectives include acquiring additional prospective gold concessions. Specific opportunities have been identified with interested concession holders. In keeping with the Suriname focus, the Company has terminated the Casa Berardi Property Option Agreement.
