Sienna Provides Clayton Valley Nevada Lithium Update

Sienna Resources Inc. (TSXV: SIE) (FSE: A1XCQ0) (OTC Pink: SNNAF) (the "Company") Sienna Resources wishes to announce that management is evaluating Sienna's Clayton Valley lithium project in Nevada. Sienna has had this property since 2016 and now that lithium prices and Clayton Valley projects in particular are showing strength, it makes sense to re-assess this project now.

Jason Gigliotti, President of Sienna Resources stated, "There has been a significant uptick in global sentiment for lithium and lithium companies. There has also been a tremendous focus on Nevada lithium in the recent months. It started with Elon Musk of Tesla Inc. recently stating he wants to develop lithium in Nevada to feed his gigafactories, and continued as Albemarle Corporation, who is a global leader in lithium, stated they also want to increase their lithium production in Clayton Valley. Lithium Americas Corp received a positive record of decision on its Thacker Pass Lithium Project January 15, 2021. On the junior front, Cypress Develop Corp, Noram Ventures Inc. and Spearmint Resources Inc have had a significant increase in shareholder interest as they all develop their lithium assets adjacent to Sienna. Sienna is currently active on multiple projects and with a massive boom in the Electric Vehicle market happening globally, the exponential need for battery metals such as lithium are seeing tremendous demand. Sienna expects to have a very active quarter."
