Sienna Resources Inc. Announces Crews

Being Mobilized on the "Elko Lithium Project"

in Elko County, Nevada

Vancouver, British Columbia--(Newsfile Corp. - October 26, 2023) - Sienna Resources Inc.

(TSXV: SIE)

(OTC Pink: SNNAF) (FSE: A1XCQ0) ("Sienna" or the "Company") is pleased to announce that it has

been notified that crews are being mobilized on its recently acquired "Elko Lithium Project" in Elko

County, Nevada.

This project consists of approximately 1,200 contiguous acres directly bordering Surge

Battery Metals' "Nevada North Lithium Project" in Elko County, Nevada.

According to the news dated

September 12, 2023 from Surge, "The first certified analytical results for the 2023 summer drilling

program at Surge Battery Metals Inc.'s Nevada North lithium project (NNLP) have returned multiple zones

of high values ranging from 1,000 parts per million to 8,070 ppm lithium, the highest grades for

exploration to date on the Nevada North Lithium Project." Sienna management cautions that past results

or discoveries on properties in proximity to Sienna may not necessarily be indicative of the presence of

mineralization on the company's properties.

Jason Gigliotti, President of Sienna states, "We are very pleased to be closer to starting the drill

program.

We anticipate additional news shortly on this front.

In other news, Surge just increased its

landholding directly to our east; Surge now surrounds Sienna's project on three sides.

That is a strong

vote of confidence for Sienna to have Surge acquire the property directly bordering Sienna."

About Sienna Resources Inc.

Sienna has recently acquired the "Elko Lithium Project" in Elko County, Nevada.

This project consists of

approximately 1200 contiguous acres directly bordering Surge Battery Metals' "Nevada North Lithium

Project" in Elko County, Nevada.

Sienna is also one of the larger landholders in Clayton Valley Nevada.

Sienna's Clayton Valley projects include the Blue Clay Lithium Project, the Silver Peak South Project,

and the Clayton Valley Deep Basin Lithium Project. Clayton Valley is home to the only lithium production

in North America, being Albemarle Corp's Silver Peak deposit.

This project is also near Tesla Motors

Inc.'s Gigafactory in Nevada. On March 18, 2021, Schlumberger New Energy Venture announced the

development of a lithium extraction pilot plant through its new venture, NeoLith Energy in a strategic

partnership with Pure Energy. The deployment of the pilot plant will be in Clayton Valley, Nevada, USA.

The NeoLith Energy sustainable approach uses a differentiated direct lithium extraction (DLE) process

to enable the production of high-purity, battery-grade lithium material while reducing the production time

from over a year to weeks. Results from this pilot plant are expected in 2023 and could have a significant

impact on the brine prospects within Clayton Valley Nevada as Sienna is located in the deepest section

of this brine deposit. One other project Sienna has is the 'Marathon North Platinum-Palladium Property'

in Northern Ontario directly bordering Generation Mining

Marathon Deposit.
