Sienna Resources Inc. Acquires Past Producing Orogenic Gold Project in Norway

Vancouver, British Columbia--(Newsfile Corp. - August 27, 2020) - Sienna Resources (TSXV: SIE) (WKN: A1XCQ0) (FSE: HRJ1) (OTC Pink: SNNAF) (the "Company") is pleased to announced that it has entered into an option agreement with EMX Royalty Corporation (NYSE: EMX) (TSXV: EMX) to acquire the "Bleka and Vekselmyr Gold Projects" in Norway. These projects are greenstone-hosted gold systems in southern Norway (see Figure 1). In particular, the Projects were acquired on the basis of past gold production at Bleka from historic mining activities and the documentation of outcropping gold mineralization in orogenic-style veins at Vekselmyr. Both Projects contain extensions of the structures that host gold mineralization that have not been tested by historic exploration programs. This now gives Sienna 4 separate projects in Scandinavia.

Jason Gigliotti, President of Sienna states, "This is a tremendous opportunity for Sienna to acquire a high quality gold project in a politically stable, mining friendly jurisdiction. We have been searching for a high quality, high potential gold project and we feel these two new gold targets provide this to Sienna immediately. This gold belt has been underexplored and we plan to commence work right away. There is a 3 km unique vein swarm within this greenstone hosted orogenic plug with a folded nose formation. This area is highly prospective for gold and we plan to focus on this area. We are extremely optimistic about Sienna's short and long term prospects when you factor this new project coupled with work expected to commence shortly on our Finland and Ontario projects at a time when we just closed an oversubscribed placement of 2 million dollars. Sienna will be very active at a time of historically high commodity prices, including gold recently making new all-time highs."

Overview of the Projects. The Projects are located in an underexplored greenstone belt in southern Norway with areas of historic gold production and documented gold occurrences. The Bleka Vein was discovered in 1880 and mined intermittently until 1940, with historic production reported as 165 kilograms (i.e., ~ 5,300 troy ounces) of gold sourced from mineralized material with an average grade of 36 g/t gold.¹ The Bleka project covers the historic mining area and swarms of similar veins that extend for at least three kilometers along strike. The nearby Vekselmyr license covers outcropping gold mineralization in similar orogenic-style veins.
