Sienna Resources announced the commencement of a high resolution ground magnetic survey on the Slättberg Cobalt-Nickel-Copper Project in Sweden. Slättberg’s massive sulfide mineralization is known to be strongly magnetic, owing to its high concentrations of pyrrhotite, a magnetic ferrous sulfide mineral associated with the Co-Ni-Cu mineralization. The new magnetic data will be used to potentially generate additional high priority drill targets on the project. Drilling is slated to commence in the coming weeks. Survey methods: Field teams are currently deployed and are using a G-859 Geometrics Cesium Vapor Magnetometer paired with a G-856AX Proton Procession magnetometer as a base station. Approximately 50-100 survey lines of 500 meters in length are planned at 25 meter spacing. The current survey will cover the central portion of the trend of historic mine workings where the initial drill program will be focused. Additional surveys will be conducted across other prioritized areas in the coming months.
