Sienna Resources engages Terraquest for Saskatchewan airborne survey
Vancouver, British Columbia--(Newsfile Corp. - June 16, 2026) - Sienna Resources Inc. (TSXV: SIEN) (OTCID: SNNAF) (WKN: A418KR) (the "Company" or "Sienna") wishes to announce that it has engaged Terraquest Ltd. of Ontario to conduct an airborne survey covering the Stonesthrow Copper-Gold Project in Saskatchewan. The survey is expected to take place in June. Jason Gigliotti, President of Sienna Resources Inc., stated, "We are looking forward to unlocking the potential of our copper-gold project in Saskatchewan.
When you couple this with our other Nevada projects, which are expected to have work commence shortly, it is clear that Sienna is entering a very active period of growth. Management would also like to acknowledge Surge Battery Metals (NILI), who have just struck a deal with the SAF Group on their Nevada North Lithium Project to fast-track a Nasdaq listing and the development of a deposit that is one of the highest-grade lithium deposits in North America¹. Considering that Sienna's property lies almost entirely within NILI's property, we are very excited to see what transpires on this deposit in the near and long term.
In my opinion, this is a truly transformational deal."
