Sienna Resources (SIE—TSX.v) (A1XCQ0 –FSE) (SNNAF—OTCBB) wishes to announce that a multi-hole drill program on Sienna's flagship nickel, copper and cobalt Slättberg Project in Sweden has now commenced.

Jason Gigliotti, President of Sienna, states, “This is a very exciting time for Sienna. It has been well over a year since our last drill program and drill results are what the market wants to see. The work programs over the past few years have enabled us to razor focus the drill program into the most highly prospective locations for nickel. Nickel prices have recently risen to 5 year highs and this is a very opportune time to be drilling for nickel. We are partnered with a NYSE mining company (EMX Royalty Corporation) on this project and we look forward to what the drilling will uncover.”

Data gathered from the 2018 Slättberg drill program, in addition to downhole Electro-Magnetic surveys and modern sampling & geophysical work have provided multiple new high priority drill targets. This work program is fully funded by cash on hand.

Slättberg is located 25 kilometers northwest of Falun, Sweden. Slättberg is a historic mining camp hosting nickel-copper-cobalt 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.
