Sienna Confirms Basal Contact Series as Primary Target for Palladium Mineralization at Kuusamo Project, Finland
Vancouver, January 22, 2021 - Sienna Resources Inc. (TSXV: SIE) ("Sienna" or the "Company") is pleased to provide an exploration update for its Kuusamo PGE-Cu-Ni Project (the "Project" or the "Property" or "Kuusamo"), located over the large Syöte Block and smaller Pirivaara Block, the southernmost intrusions that comprise the Koillismaa Layered Igneous Complex ("KLIC"), in north-central Finland. The Project is located about 19 km south of Palladium One Mining's LK Project, covering two of the northern blocks within the KLIC, who are targeting basal Contact-Type PGE-Cu-Ni sulphide mineralization.
The KLIC is part of a suite of Paleoproterozoic continental rift-related intrusions which are highly prospective for PGE-Cu-Ni deposits such as the nearby Suhanko (Arctic Platinum Oy) deposit located about 100 km northwest of the Project. Suhanko hosts SAMREC Code Compliant Measured and Indicated resources of 5.4 million ounces of palladium grading 1.44 g/t Pd and 1.3 million ounces of platinum grading 0.35 g/t Pt at a cut-off of 1.0 g/t Pt+Pd+Au, as well as Inferred Resources of 4.4 million ounces of palladium grading 1.50 g/t Pd and 1.1 million ounces of platinum grading 0.38 g/t Pt (www.suhanko.com). Management cautions that past results or discoveries on properties in proximity to Sienna may not necessarily be indicative to the presence of mineralization on the Company's properties.
The highly prospective Kuusamo Project has the potential to host similar styles of basal PGE-Cu-Ni mineralization (Contact-Type) found at the LK Project and associated with the basal contact of the Syöte Block. Historical mapping and diamond drilling at Kuusamo has outlined an approximately 23 km long basal contact horizon along within the Syöte Block which is prospective for Contact-Type PGE-Cu-Ni sulphide mineralization.
Sienna recently completed orientation soil surveys (total of four sections) over the interpreted contact region of the Syöte and Pirivaara blocks (Figure 1). The soil samples, which targeted the B-horizon in the soil profile, were analysed using partial leach methods to identify mobile metals interpreted to be derived from local sulphide-rich source rocks. In three of the four test sections, the targeted geologic horizon (contact region) showed anomalies in a combination of vector elements including palladium, copper, nickel, and gold. Background concentrations for the vector elements were established at 0.09 ppb Pd, 400 ppb Cu, 70 ppb Ni, and 0.05 ppb Au. The lower limit of detection ("LLD") for these elements are 0.05 ppb Pd, 1 ppb Cu, 1 ppb Ni, and 0.02 ppb Au.

Anomalous soil samples returned concentrations in the vector elements that ranged from LLD to 0.21 ppb Pd, 109 to 783 ppb Cu, and 33 to 137 ppb Ni, and LLD to 0.16 ppb Au in section Site #1 (Figure 1 - panel A), from LLD to 0.29 ppb Pd, 121 to 846 ppb Cu, 68 to 236 ppb Ni, and LLD to 0.57 ppb Au in section Site #3 S1 (Figure 1 - panels B and C), from LLD to 0.31 ppb Pd, 109 to 3190 ppb Cu, 42 to 1120 ppb Ni, and LLD to 0.71 ppb Au in section Site #3 S2 (Figure 1 - panels B and C), with anomalies positioned at or near the targeted basal units of the two KLIC blocks. Results from section Site #2 were mostly LLD or below the determined background concentrations.
Results from the orientation soil sampling program reflect a highly encouraging "proof of concept" for this rapid and inexpensive sampling technique, and provides the confidence for this technique to be used to screen larger target areas within the Project, in a highly cost-effective manner.
The most encouraging aspect of the sampling program were the particularly strong anomalies seen in the southernmost sampling lines in the Pirivaara Block (Figure 1). The Pirivaara Block is an outlying exposure of the KLIC that crops out from beneath glacial cover in the southeastern portion of the Project. Little is known about this particular exposure of the KLIC, but the Sienna soil sampling results shows evidence of strong anomalism in copper and nickel (Figure 1 - panel C), and palladium and gold (Figure 1 - panel B). As a result of these positive indications, this area, along with the basal contact in the Syöte Block, will be prioritized for further work.
Plans for continued exploration on the Kuusamo project include broader sampling programs using the same soil sampling techniques employed in this initial phase of sampling, as well as geophysical surveys (Induced Polarization or "IP" and detailed ground magnetics) targeting the prospective basal portions of the intrusive blocks. The aim of the broader exploration programs will be to identify the highest priority drill targets on the Project.
Jason Gigliotti, President of Sienna Resources stated, "We are very pleased and excited regarding the data gathered to date in Finland. The basal contact is 23 km long and is the primary target for this project, showing similar characteristics and geological orientation as the bordering project of Palladium One Mining. We are very encouraged at this stage, and are highly motivated to get the next phase underway. Not only is Sienna active in Finland, but we are underway in Norway on our Bleka Gold Project and revaluating plans in Clayton Valley, Nevada on our Clayton Valley Deep Basin Lithium Project, that lies in the deepest section of the brine where Pure Energy Minerals is currently drilling. The Clayton Valley is home to Albemarle's Silver Peak Lithium brine operation which is the only producing lithium brine deposit in the USA. Management is very optimistic about the prospects of 2021 as the company will have multiple shots on goal for success."

Soil samples were submitted for analyses at ALS Scandinavia AB (ALS Global) whose laboratories are accredited by SWEDAC for several analytical methods and whose accreditation implies their compliance with the international standard ISO 17025 and ISO 9001:2000. The ALS Global Ionic Leach assay method identifies anomalous mobile metal ions which may have been mobilized and trapped within the soil profile, giving good indications of mineralized bodies under deep cover.

Sienna is partnered with a New York Stock Exchange-listed mining company on three separate projects in Scandinavia including the past-producing Bleka and Vekselmyr orogenic gold projects in southern Norway which are both greenstone-hosted gold systems, the Kuusamo platinum group elements (PGE) project in Finland directly bordering the LK Project being advanced by Palladium One Mining Inc., and the platinum-palladium-nickel Slattberg project in southern Sweden. In North America, Sienna's projects include the Marathon North platinum-palladium property in Northern Ontario directly bordering Generation Mining Ltd.'s 7.1-million-ounce palladium-equivalent Marathon deposit. Sienna also has the Clayton Valley Deep basin lithium project in Clayton Valley, Nev., home to the only lithium brine basin in production in North America, in the direct vicinity of Albemarle Corp.'s Silver Peak deposit and Tesla Motors Inc.'s Gigafactory. Management cautions that past results or discoveries on properties in proximity to Sienna may not necessarily be indicative to the presence of mineralization on the company's properties.
