Sienna Acquires the 10,845 Acre "Dragon

Uranium Project" Bordering Cameco in the

Athabasca Basin of Saskatchewan

Vancouver, British Columbia--(Newsfile Corp. - January 17, 2024) - Sienna Resources Inc. (TSXV: SIE)

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

acquired the 10,845 contiguous acre "Dragon Uranium Project" bordering Cameco Corporation (CCO,

CCJ) in the world renowned Athabasca Basin of Saskatchewan.

According to the World Nuclear

Association (WNA), the highest-grade uranium mine in the world is Cameco's Cigar Lake in the

Athabasca Basin of Saskatchewan, Canada. It has an average grade of 14.69% U3O8. The Athabasca

Basin is home to the highest-grade uranium deposits in the world, which includes the highest grade

uranium mine in the world owned by Cameco Corporation.

In 2021, the Fraser Institute ranked

Saskatchewan as number one in Canada, the second-best jurisdiction globally. 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, "Uranium prices have hit a 16 year high this week and

management feels that diversifying into uranium while keeping our lithium focus makes sense.

Establishing a large footprint in the most prolific uranium address on the globe bordering the biggest

name in uranium, Cameco, provides Sienna and Sienna shareholders with exposure to the best

performing sector in mining in the past year. Management continues to try to add projects that are

accretive to the growth of Sienna and we have enough cash on hand to forward these projects."

About Sienna Resources Inc.

Sienna has recently acquired the 10,845 contiguous acre "Dragon Uranium Project" bordering Cameco

Corporation (CCO, CCJ) in the world renown Athabasca Basin of Saskatchewan.

Also, Sienna recently

expanded the "Elko Lithium Project" in Elko County, Nevada.

This project consists of approximately

1840 contiguous acres directly bordering Surge Battery Metals' (NILI)

"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 (ALB) Silver Peak deposit.

This project is also near Tesla Motors

Inc.'s (TSLA) Gigafactory in Nevada. On March 18, 2021, Schlumberger New Energy Venture (SLB)

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

a strategic partnership with Pure Energy (PE). 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 2024 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.

This project was acquired via staking.
