SIENNA RESOURCES INC. ANNOUNCES CREWS BEING MOBILIZED ON THE "ELKO LITHIUM PROJECT" IN ELKO COUNTY, NEVADA

Sienna Resources Inc. 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 Sept. 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 1,200 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, United States. 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's Marathon deposit.
