SIENNA RESOURCES INC. LOOKING TO COMMENCE OPERATIONS IN NEVADA ON ITS LITHIUM PROJECTS

Sienna Resources Inc. is planning to recommence operations in Nevada on its lithium projects. These include the Cave Creek lithium project, which is located within Surge Battery Metals Inc.'s project area, and the Clayton Valley Deep Basin lithium brine project, which lies within SLB Ltd.'s (formerly Schlumberger) lithium brine project area. According to the Trading Economics website, lithium prices have increased by over 150 per cent since June, 2025.

Jason Gigliotti, president of Sienna, states: "Lithium prices have been moving up at a very rapid rate, similar to many other commodities, as reported by kitco.com. Lithium prices have increased by more than 150 per cent since June, 2025, and we believe this presents a favorable environment to become more active on our projects. With approximately $1.5-million in cash, the company is in a strong financial position to advance its Nevada lithium assets. Management expects to be active on these projects in 2026."
