Sienna Resources Inc. (TSXV: SIE) (OTC PINK: SNNAF) (FSE: A1XCQ0) ("Sienna" or the "Company") is pleased to announce that it has engaged Radai Ltd. of Oulu Finland for the planned work program in Finland. This program is expected to commence shortly.

Jason Gigliotti, President of Sienna states, "We are pleased to engage Radai Ltd to assist in the planned work program in Finland. Radai has extensive local knowledge of the area and protocols and we look forward to working directly with them on this exciting project. On July 7 2021, Palladium One Mining Inc. (PDM-tsx.v) announced 'new surveys confirm an over 75% increase in the Kaukua South IP chargeability anomaly, which is now greater than 7 kilometers in strike length.' The Sienna property virtually surrounds the Palladium One property (see map) and we are very enthused about commencing operations on the Sienna property shortly. Not only are we looking to start this project, but we are currently completing our gold drill program in Norway and expect to commence operations in Ontario shortly as well. Clearly this summer will be a very active period for Sienna."
