SIENNA APPLIES FOR DRILL PERMIT FOR UP TO 5 INITIAL LOCATIONS ON THE "ELKO LITHIUM PROJECT" IN ELKO COUNTY, NEVADA BORDERING SURGE BATTERY METALS

Sienna Resources Inc. has submitted an application with the Elko District BLM (Bureau of Land Management) office to drill up to five initial locations on its recently acquired Elko lithium project in Elko county, Nevada. This project consists of approximately 1200 contiguous acres directly bordering Surge Battery Metals' (NILI) "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 have submitted an initial 5 hole drill plan location notice to the Elko District BLM office. We are very excited about this area especially in light of the fantastic lithium results being drilled by our neighbour, Surge Battery Metals. This area is shaping up to be one of the most exciting lithium addresses in North America and we very pleased to be right in the heart of it with a planned work program to commence as soon as possible. Not only do we have this new lithium project, but Sienna is one of the largest landholders in Clayton Valley, Nevada through its other property interests. Sienna has more than enough cash on hand for anticipated current exploration plans and we expect to very active on multiple fronts in the remainder of 2023. Management is very optimistic about the future and looks forward to what will happen in the ground on these projects."

Recently, the Bureau of Land Management (BLM) has given Sienna approval for up to 4 additional holes to be completed on the 100% owned Blue Clay Lithium Project in Clayton Valley, Nevada. On March 25, 2022, Sienna revealed a new lithium discovery on the Blue Clay Lithium Project. Lithium values as high as 1230 ppm Li were encountered. The Blue Clay Lithium Project consists of 150 contiguous claims totaling approximately 2,950 acres prospective for lithium right in the heart of the Clayton Valley in Nevada, which is currently home to the only producing lithium region in North America.

About Sienna Resources Inc.

Sienna is 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. The 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. Sienna also has "Elko Lithium Project" in Elko County, Nevada. This project consists of approximately 1200 contiguous acres directly bordering Surge Battery Metals' (NILI) "Nevada North Lithium Project" in Elko County, Nevada. One other project Sienna has is the 'Marathon North Platinum-Palladium Property' in Northern Ontario directly bordering Generation Mining Marathon Deposit.
