Sienna Resources has initiated a drill program on its flagship Slättberg PGE-Ni-Cu project 25 kilometers (km) northwest of the historic mining city of Falun, Sweden. The PGE-Ni-Cu enriched mineralization remains open at depth and along strike. The abundance of sulphides, higher platinum group element values, and a swarm of mafic dikes suggest that Sienna is moving closer to a source area for the sulphide mineralization and associated mafic intrusions as it drills to progressively deeper levels.

The current 1,000-m drill program will test the continuation of the PGE-Ni-Cu massive sulphide mineralization in the western part of the project with two or three drill holes. Another drill hole will follow-up earlier drill results.

Slättberg is a historic mining camp hosting cobalt and PGE enriched nickel-copper sulphide mineralization along a 2-km belt of historic nickel-copper mines. The project contains drill defined zones of massive sulphide mineralization that extend to about 100 m in depth, which is also the approximate depth of historic mining in the area. At least 16 historic mines are located on the property, with historic operations dating back to the late 1800s.
