Sankamap Metals Highlights Historical Exploration Work at the Kuma Property

Edmonton, Alberta--(Newsfile Corp. - May 22, 2025) - Sankamap Metals Inc. (CSE: SCU) ("Sankamap" or the "Company") is pleased to provide historical exploration results from the Oceania Project's 4,500-hectare ("Ha") Kuma property ("Kuma"), located in Guadalcanal, Solomon Islands. The Kuma property is situated 37 kilometers ("km") southeast of Honiara, the capital city of Guadalcanal. Historical exploration at Kuma has identified large-scale copper-gold ("Cu-Au") mineralization and promising indicators of a potential porphyry deposit, which remains untested by drilling (see regional location in our May 7, 2025 press release).

CEO John Florek commented "We are enthusiastic about the discovery potential at the Kuma property, where historical exploration has outlined a kilometer-scale Cu-Au anomaly, including surface samples grading up to 13.5 g/t gold and 11.7% copper³; remarkably, this area remains untested by drilling. The Kuma property presents an exceptional exploration opportunity, located along a highly prospective copper-gold trend that hosts several major deposits, including Lihir¹ and Panguna⁶. By building on previous work, we aim to further refine our porphyry target, strengthening the foundation for our upcoming drill program and creating long-term value for our shareholders."

Exploration Highlights

• Rock chip sampling on the Kuma property returned assays of up to 13.5 g/t gold and 11.7% copper.

• Kilometer-scale Cu-Au anomalies were delineated through rock and soil geochemical assays.

• Hydrothermal alteration mapping delineated a lithocap extending over 2 kilometers, characterized by distinct zones of phyllic, advanced argillic, and argillic alteration

Initial exploration at the Kuma property began in the 1990s, with the identification of massive oxidized boulders, which were subsequently traced upstream to Alemba Creek in 2007 (Figure 1), leading to the delineation of the Kuma prospect. Between 2007 and 2019, exploration efforts included soil and rock geochemical sampling, geological and alteration mapping, and airborne geophysical surveys. Hyperspectral analysis defined a >2 km lithocap with well-developed phyllic, argillic, and advanced argillic alteration assemblages, indicative of a high-sulphidation epithermal to porphyry-style system. Geochemical data revealed kilometer-scale anomalies in both gold and copper within the lithocap, highlighting significant, untested mineral potential.
