(TSXV: SIE) (OTC Pink: SNNAF) (FSE: A1XCQ0) ("Sienna" or the "Company") is pleased to announce that the maiden multi-hole drill program on the Blue Clay Lithium Project in Clayton Valley, Nevada is now underway.

Jason Gigliotti, President of Sienna Resources, states: "It is very exciting to commence our maiden drill program on the Blue Clay Lithium Project right in the heart of the Clayton Valley, the preeminent address for lithium in North America.
