Bastion Minerals Ltd (ASX: BMO) has announced positive results of a recent magnetic survey at the Gyttorp property located in Örebro County, Sweden.
The licence, which covers 138.4km², is situated within a historically significant mining region with established infrastructure. Recent geological fieldwork, a comprehensive geophysical survey, and assay results have confirmed the presence of significant copper and rare earth element (REE) mineralization, including the extension of previously identified high-grade trends, and the discovery of new prospective areas. These developments provide a solid foundation for the next stages of exploration and drilling.
The property has high-grade REE mineralization (up to 7.27% TREE+Y) associated with magnetite skarns, and areas of associated copper (returning values of between 2.5% and 8.5% copper).
The new ground survey improved the REE volume potential threefold, through discovery of Trend B, 100m south and west, and parallel to, the original mineralization (Trend A). Trend B extends for 1,000m, parallel to the >500m Trend A on the north limb of a major fold.
Strong SW copper zone, with > 1% Cu rock samples. Two E-W striking Cu-rich magnetic trends can be now distinguished, with a possible third discontinuous body in between.
These high priority targets coincide with high-grade assays of REE mineralization, including significant quantities of heavy rare earth elements, with some samples reporting a HREE/LREE (light rare earth elements) ratios of up to 57%.
REE and copper mineralization is associated with zones of magnetite skarn, which manifests as zones of high magnetic response in the government magnetic data sets. The high magnetic response, presence of extensive mapped historical magnetite mines, and the presence of REE and copper in historical analyses, has provided a means of rapidly focusing into the areas of highest potential.
Additionally, based on the findings from fieldwork, geophysics, and assays, Bastion Minerals has outlined potential drilling programmes aimed at testing the continuity of these REE and copper rich zones, both close to surface and at depth.
