Sienna Commences Drilling on the Bleka Gold Project in Norway

Vancouver, B.C., May 28, 2021, Sienna Resources Inc. (“Sienna” or the “Company”) (SIE—TSX.v, SNNAF—USA, A1XCQ0–Germany) is pleased to announce that drilling at the Bleka Gold Project in Norway is now underway.  A total of approximately 1,500 metres will be drilled on this phase of drilling. The Bleka vein was discovered in 1880 and mined intermittently until 1940.  The historic Bleka vein is hosted in a deformed greenstone belt in southern Norway and was formed during two phases of quartz-veining events. Auriferous quartz veins characteristically contain Cu-Bi (copper-bismuth) and tourmaline. Compilation of historic reports combined with reconnaissance mapping revealed a series of underexplored vein swarms on the Bleka property that will be tested on this drill program.  Drilling is expected to take between 2-4 weeks to complete.

Jason Gigliotti, President of Sienna states, “We are very pleased to commence our first major drill program of 2021.  Gold prices are trending higher and we could not be more optimistic about this drill program in this past producing gold region.  Scandinavia is one of the world’s top mining jurisdictions and we look forward to what will be uncovered on our maiden drill program in Norway.  Not only are we now drilling in Norway, but we are also expecting field programs to commence shortly on our Marathon North Platinum-Palladium Project in Ontario directly bordering Generation Mining Ltd.’s 7.1-million-ounce palladium-equivalent Marathon deposit and our Kuusamo Platinum Group Elements (PGE) Project in Finland directly bordering the LK Project being advanced by Palladium One Mining Inc. Sienna is one of the largest landholders in this region of Finland.  Management is very enthused about what will transpire on the multiple drill/work programs planned for the next few months.  This will be one of the most active periods in Sienna’s history.”  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.
