Exploration results at Haapaniemi prospect in Finland

Great Northern Minerals Limited (ASX:GNM) has announced the discovery of a newly defined swarm of highly fractionated pegmatite dykes over a 600m2 area at the Haapaniemi prospect, part of its 100%-owned Sukula Project in Finland. The core zonation of highly fractionated pegmatites offers a promising drill target with the possibility of spodumene zones concealed at depth. Portable XRF (pXRF) measurements on microcline revealed high rubidium (Rb) levels up to 5,562 ppm, indicating highly fertile pegmatites. Assays returned up to 538 ppm Li2O, 256 ppm Ta2O5, 118 ppm Cs2O, and a K/Rb ratio as low as 12, supporting a very high degree of fractionation.

Executive commentary on the exploration results

GNM CEO & Managing Director, Cameron McLean said, 'GNM is excited by the success of our recent fieldwork at Sukula. The Haapaniemi prospect provides GNM with an exciting drill target, bolstering our confidence in a potential lithium discovery within the Somero lithium province, located 8km from United Lithium's Kietyonmaki deposit. We are encouraged by the results and look forward to progressing Haapaniemi further.'

Summary of the exploration results and outlook

The exploration results at the Haapaniemi prospect in Finland have revealed a promising drill target with highly fertile pegmatites and the potential for a lithium discovery. GNM is considering various geochemical and geophysical methods to progress the prospect towards a drill-ready target. The project's proximity to known lithium pegmatite swarms and the favorable whole rock geochemistry and pXRF results provide an optimistic outlook for GNM's exploration efforts at the Sukula Project. The company's ambitions to further develop the Haapaniemi prospect and the Sukula Project align with its strategic focus on mineral exploration and development.
