Sienna Update on Norway Gold Project

Sienna Resources Inc. (TSXV: SIE) (FSE: A1XCQ0) (OTC PINK: SNNAF) (the "Company") Sienna Resources is pleased to announce the commencement of field exploration at the Bleka Gold Project in Norway. 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 gt gold1.  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 and tourmaline2. Compilation of historic reports combined with reconnaissance mapping revealed a series of under-explored vein swarms on the Bleka property. Earlier this year, a systematic sampling program to test the vein swarms was initiated to identify gold-rich vein sets. Results were encouraging with over 10% of samples showing anomalous gold results (6 of 52 rockchip samples contained more than 0.1 ppm Au)3.  Historic reports show rock chip samples with similar quantities of anomalous results with some vein samples reaching up to 103 gt Au4.  As a result of this field work, previously unknown quartz veins were discovered and follow-up soil sampling is currently being conducted in an attempt to identify additional buried quartz veins.

Going forward Sienna has planned more surface sampling coupled with a planned UVA supported magnetic survey which will delineating important structural features to generate  high priority drill targets. Over the coming weeks the historic mine maps will be compiled to create 3D model of the known mineralization and drill planning will commence to test mineralized continuation down plunge and along strike from the existing mine workings.  SIE has not performed sufficient work to verify the published data reported above, but SIE believes this information is considered reliable and relevant.
