Sienna Resources Inc Commences Operations On

Slattberg Cobalt-Nickel-Copper Project in Sweden

Vancouver, British Columbia--(Newsfile Corp. - January 25, 2018) - Sienna Resources (TSXV: SIE) (FSE: A1XCQ0) (OTC

Pink: SNNAF) is pleased to announce 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.

Jason Gigliotti President of Sienna Resources states, "We are pleased to have started up operations on the Slättberg Cobalt-

Nickel-Copper.

We have recently closed an oversubscribed placement of $2.5 million and we plan to deploy this cash

strategically and immediately.

We plan to be very active on this project and expect to be drilling in the coming weeks.

The global

demand on battery metals such as cobalt continues to strengthen and we are very optimistic about our 2018 work programs."

About Sienna Resources Inc.:

Recently Sienna received TSX Venture approval to go forward into an exploration and option agreement to acquire the Slättberg

Cobalt-Nickel-Copper Project in Sweden (the "Project") from EMX Royalty Corporation ("EMX") (EMX-NYSE, tsxv) (announced

December 4, 2017). The Project consists of two adjacent exploration permits comprising approximately 9513 contiguous acres.

Jason Gigliotti president of Sienna states, "We are very pleased to receive approval for this exciting cobalt-nickel-copper

prospect.

Cobalt prices have just crossed fresh ten year highs, and we look forward to advancing this prospect.

There are 12

historic mines on this property and with modern mining approaches, we are very optimistic about what this project could

contain."

Northvolt is planning to be the largest battery factory in Europe at roughly the same size as Tesla's Gigafactory. Jason Gigliotti

states "Northvolt wants to locally source as much battery material as possible such as cobalt and nickel. There are now more

than 20 mega battery factories currently being planned or constructed globally, creating a massive demand on the battery metals

such as lithium, cobalt and nickel. Sienna is focused on exploring and developing projects that will meet this insatiable demand."

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 12

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.
