Sienna Completes Phase I Drill Program on the Blue Clay Lithium Project in Clayton Valley, Nevada

Sienna Resources Inc. (TSXV: SIE) (OTC Pink: SNNAF) (FSE: A1XCQ0) ("Sienna" or the "Company") is pleased to announce that phase I drilling has now been completed at the 100-percent owned "Blue Clay Lithium Project" consisting of 150 contiguous claims totalling approximately 2,950 acres. The "Blue Clay Lithium Project" is prospective for lithium and is located right in the heart of the Clayton Valley of Nevada, which is currently home to the only producing lithium region in North America. Approximately 100 samples have been shipped to ALS in Reno on a rush basis. Results are expected back in 4-8 weeks.

Jason Gigliotti, the President of Sienna Resources stated, "We are pleased to have completed this first phase of drilling on the Blue Clay Lithium Project. We are eagerly awaiting the results, especially in light of the significant commodity boom the entire complex is experiencing right now. Lithium is currently at its all-time highs and is up over 900 percent since the beginning of 2021. Palladium prices are also near their highs which bodes well for our palladium projects in Ontario and Finland. The next quarter is shaping up to be very transformative for Sienna Resources."
