VANCOUVER, British Columbia, Feb. 18, 2020 (GLOBE NEWSWIRE) -- Sienna Resources Inc. (SIE—TSX.v) (A1XCQ0—FSE) (SNNAF—OTCBB) (the “Company”) is pleased to announce that it has significantly increased its land holdings on its Marathon North Platinum-Palladium Property to approximately 16,500 acres (from approximately 2,500 acres announced in a news release on Jan. 23, 2020) in Northern Ontario directly bordering Generation Mining Limited’s Marathon Palladium Project. This new acreage makes Sienna one of the largest landholders in the Coldwell Complex other than Generation Mining. The Coldwell Complex is the largest alkaline complex in North America and hosts the Marathon platinum-palladium deposit. According to Generation Mining’s webpage, the Marathon deposit is ‘one of’ the largest undeveloped platinum group metal mineral resources in North America hosting several PGM-Cu (platinum-group-metal-copper) deposits, including the 7.1-million-ounce palladium-equivalent Marathon Deposit. On January 6, 2020, Generation Mining Ltd. released a preliminary economic assessment (PEA) giving Marathon an after-tax net present value (NPV) of $871 million.

Jason Gigliotti, President of Sienna, stated, “This new land acquisition places Sienna as one of the largest landholders in this region directly bordering Generation’s platinum-palladium deposit.  As palladium prices are right near all-time highs, this new acquisition gives Sienna two large size platinum-palladium projects with work programs simultaneously being planned.  Not only do we expect to commence operations on this new project in Ontario but we also anticipate drilling to start in the coming weeks on our Flagship Platinum-Palladium-Nickel Slättberg Project in Sweden, on which we are partnered with a NYSE mining company.  Management anticipates that the coming months will be transformative in Sienna’s corporate growth trajectory. These are exciting times for Sienna’s management and shareholders.”
