Drilling underway at Sienna's Case Lake West Project in NWO

Mar 6, 2025


Sienna Resources Inc. has announced that a multi- hole drill program is now underway on Sienna's 100% owned 'Case Lake West Cesium and Spodumene Pegmatite Project' in Ontario. 

Jason Gigliotti, President of Sienna Resources, stated, "We are extremely pleased and excited to finally be underway on a drill program. It has been a long time since Sienna has drilled. The 'Case Lake West Cesium and Spodumene Pegmatite Project' has potential for cesium. When you consider that this project directly borders Power Metals Corp., whose shares increased approximately 300% in February based on their Case Lake deposit news, we couldn't be more excited about getting boots on the ground. These next few weeks/months will be a watershed mark for Sienna as the drilling occurs."

The 'Case Lake Cesium Project', owned by Power Metals Corp., is a highly prospective lithium, cesium, and tantalum (LCT) project in northeastern Ontario, Canada. Here are some of the highlights: 

  • High-grade mineralization: Recent drilling programs have consistently confirmed high-grade cesium mineralization, with standout results including up to 20.67% Cesium Oxide (Cs₂O). Exceptional Tantalum grades of up to 5328ppm have also been recorded.
  • Shallow mineralization: The cesium mineralization is often found at shallow depths, which could make the project more economically viable. 
  • Multi-element potential: In addition to cesium, the project also contains significant lithium and tantalum mineralization, further enhancing its value. 
  • World-class asset: The Case Lake project is considered a world-class asset due to the high grades and significant size of the deposit. 
  • Strategic importance: The project's high-grade cesium and tantalum resources are strategically important for meeting the growing global demand for these critical minerals in advanced technologies.

Overall, the Case Lake Cesium project is a promising project with the potential to become a significant supplier of cesium, lithium, and tantalum. Management cautions that past results or discoveries on properties in proximity to Sienna may not necessarily be indicative of the presence of mineralization on the company's properties.

About Sienna Resources Inc.

Sienna has significantly increased acreage of the "Stonesthrow Gold Project", consisting now of approximately 31,718 contiguous acres prospective for gold. Sienna has also recently acquired the "Case Lake West Cesium and Spodumene Pegmatite Project" in Larder Lake Mining division of Ontario, Canada roughly 100 km north of Kirkland Lake, NE Ontario. This project consists of approximately 7,850 contiguous acres prospective for Cesium and Spodumene Pegmatites. Sienna has also just acquired the 10,357 acre "Uranium Town Project" bordering Denison Mines Corporation , the now 23,134 contiguous acre "Dragon Uranium Project" bordering Cameco Corporation, and the 55,440 acre "Atomic Uranium Project" in the world renowned Athabasca Basin of Saskatchewan. Also, Sienna has the "Elko Lithium Project" in Elko County, Nevada consisting of approximately 1830 contiguous acres directly bordering Surge Battery Metals' "Nevada North Lithium Project" in Elko County, Nevada who announced the highest-grade lithium deposit in the USA. Sienna is also one of the larger landholders in Clayton Valley Nevada. Sienna's Clayton Valley projects include the Blue Clay Lithium Project, the Silver Peak South Project, and the Clayton Valley Deep Basin Lithium Project. Clayton Valley is home to the only lithium production in North America, being Albemarle Corp's Silver Peak deposit. This project is also near Tesla Motors Inc.'s Gigafactory in Nevada. On March 18, 2021, Schlumberger New Energy Venture announced the development of a lithium extraction pilot plant with a strategic partnership with Pure Energy. Management cautions that past results or discoveries on properties in proximity to Sienna may not necessarily be indicative of the presence of mineralization on the company's properties.
