Sienna Resources Completes Multi Hole Drill Program at Slättberg Cobalt-Nickel-Copper Project in Sweden

Sienna Resources (TSXV:SIE) (FSE:A1XCQ0) (OTCBB:SNNAF) wishes to announce the completion of the first phase of drilling on its Slättberg Cobalt-Nickel-Copper Project in Sweden (the “Project”).  A total of 942 metres were drilled and 72 samples have been shipped for assaying.  The results are expected in 2-6 weeks.

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.

About Sienna Resources Inc.:

The Slättberg Cobalt-Nickel-Copper Project consists of three adjacent exploration permits comprising approximately 12,733 contiguous acres.

Slättberg is located 25 kilometers northwest of Falun, Sweden. Slättberg is a historic mining camp hosting cobalt-nickel-copper rich massive sulfide mineralization that occurs within a two kilometer belt of historic nickel-copper mines. The Project contains drill defined massive sulfide mineralization that extends to ~100 meters in depth, and remains open for expansion at depth and along strike.  The Project is accessible year round, with nearby rail, power and 5 smelters in the Nordic region.  At least 16 historic mines are located on the property, with historic operations dating back to the late 1800’s.

Mineralization at Slättberg is hosted by 1.8-1.9 Ga (Svecofennian) supracrustal rocks (metavolcanics and metasediments) located along the southwestern flank of a large gabbroic intrusive complex. The historic mines are positioned along an east-west trend of massive sulfide occurrences developed in and around a similarly oriented body of “leptite”. This is a local term used to describe rhyolitic/felsic tuffaceous rocks commonly associated with sulfide mineralization in Bergslagen. Mafic and ultramafic rocks also occur in and around the mine workings.

Sweden is at the forefront of an exploration and development boom in the mining industry. The country’s favorable business environment includes a low corporate income tax rate, a proactive geological survey, and broad public support for export-led resource extraction. Sweden has a long history of mining, and is host to some of Europe’s largest active mines.
