Sienna Resources Inc. ("Sienna" or the "Company") (TSXV: SIE) (OTC Pink: SNNAF) (FSE: A1XCQ0) wishes to announce that going forward the company will focus on the lithium projects in Nevada. Lithium prices have continued to show incredible strength all year and are currently at all-time highs today.

On March 25, 2022, Sienna revealed a new lithium discovery on the 100% owned Blue Clay Lithium Project in Clayton Valley, Nevada (See map below). 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.

Jason Gigliotti, President of Sienna Resources, states: "We have made the decision to focus primarily on the lithium projects in Nevada. Management feels that these projects represent the best option for growth going forward and with no other obligations on other projects, the company is far more razor focused on the highest priority projects. Lithium prices are at all-time highs so management feels that this is the best path forward for our shareholders. We are excited about the near and long term future of Sienna in regards to the lithium focus."
