European Resources continues to advance its Finland Project – the Korsnas and Jokikangas rare earth element (REE) projects through its 100% owned Finnish subsidiary Bambra. European Resources geological team has extensive in-country experience and the 2023 acquisition of Bambra added a local permitting and administration team with deep regional expertise.
The Geological Survey of Finland (‘GTK’) had already completed extensive mapping and sampling of the mineralised horizons. The Company was able to access a comprehensive, archived dataset at Kornas including preserved drill core, drill logs, plans and sections from the old Korsnas lead mine and surrounding areas.
The Korsnas REE project surrounds an old mine at Korsnas which was mined between 1959 and 1972, yielding 0.87Mt of ore averaging 3.6% Pb, allanite and a few other REE minerals which made the deposit prospective for REE.
During pilot production of a REE concentrate in the early 1970s, the ore proved to contain 0.83% RE2O3. The occurrence is in a north-south trending fault zone filled with a vein comprising coarse grained calcite, feldspar, diopside, REE bearing apatite.
The total REE content of samples taken by previous mine operators ranges from 0.7% to 2.2% with LREE dominating the REE budget. Eu content is high, ranging from 66 to 242 ppm and Th content ranges from 107 to 604 ppm.
A three pronged approach – linked to separate areas – to advancing Korsnas (since April 2023)
Jokikangas and Honkamäki cover a REE vanadium mineralised belt of rocks.
Elongated bodies of up to 2.0% REE are characterised by sericitic alteration and a spatial relationship with pegmatities in a mineral assemblage including fergusonite (Nb, Y, REE0, allanite (LREE) and columbite-tantalite (Nb).
Exploration tenure surrounds the Kontioaho and Katajakangas targets held by Otanmaki (O5) Oy with mineralisation continuous and lightly drilled. Mineralisation at Katajakangas has ~12m thick high grade zone in its central part, surrounded by a lower grade zone at the margins.
Based on archived drillhole data, there is an along strike opportunity to the northwest of Otanmaki (05) Oy’s Kontioaho operation and to the west of the Katajakangas operation (both shown as red dots in the Otanmaki (05) Oy tenement in the above map) onto the Jokikangas project.
