Sienna Resources to Commence drilling on Flagship

Slattberg Nickel-Copper-Cobalt Project in Sweden

Vancouver, British Columbia--(Newsfile Corp. - June 17, 2019) - Sienna Resources (TSXV: SIE) (FSE: A1XCQ0) (OTC Pink:

SNNAF) wishes to announce that a multi-hole drill program is planned to begin in Summer 2019 on Sienna's flagship nickel,

copper and cobalt Slättberg Project in Sweden.

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.

Jason Gigliotti, President of Sienna states, "The initial results of the 2018 drill program were encouraging but further target

definition was required.

Follow up EM surveys and new sampling has provided new multiple high priority drill targets, which we

plan to test this summer. We look forward to a very active 2019 as we still have cash reserves to cover the planned drill

program."

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.
