SIENNA COMPLETES THE FIRST PHASE OF DRILLING ON THE "ELKO LITHIUM PROJECT" IN ELKO COUNTY, NEVADA

Sienna Resources Inc. has completed drilling for the first phase on its recently acquired Elko lithium project in Elko county, Nevada. Samples are being prepared for delivery to the lab for assay.

Jason Gigliotti, President of Sienna states, "We are pleased that we were able to get this first phase of drilling completed before the winter conditions take over the area. We look forward to the data this first phase of drilling will show on the project and will guide the next phase of drilling. We have only worked on a very small percentage of the acreage to date based on weather and have larger plans for the next phase of work."New Elko County MapTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/854/187264_bad09b66d44a394e_002full.jpg

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' (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 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.
