About Sienna Gold: Sienna Gold Inc. (SGP: TSX.V; SGP: BVL) is a Canadian-based exploration and development company with assets in northern Peru. Igor, the Company's 100%-owned flagship gold and silver project, is located in a prolific gold district in eastern La Libertad Department. Recent exploration on the Callanquitas Structure has discovered a significant gold and silver resource, open along strike and at depth. Parallel structures are unexplored and, coupled with the Domo and Tesoros targets, highlight the exploration potential at Igor. The initial Inferred Resource for the Callanquitas Structure is 7.2 million tonnes grading 1.9 grams per tonne (gpt) gold and 71.8 gpt silver; this equates to 3.16 gold equivalent (Au Eq(i)) gpt using a cut-off grade of 1.5 Au Eq(i) gpt. This is approximately 448,500 ounces of gold and 16,600,000 ounces of silver, or 730,500 Au Eq(i) ounces. The relevant NI 43-101 technical report was filed on December 17, 2012 and can be seen on the Company's website (www.siennagold.com) or on SEDAR (www.sedar.com). Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource will be converted into mineral reserves.

Sienna Gold plans to drill the Callanquitas Structure during 2013, to expand the existing resource. The Company will also begin drilling on other targets at Igor in order to identify new gold-silver zones. The Company intends to update its mineral resource estimate in the second half of 2013 as a prelude to an initial Preliminary Economic Assessment (PEA) in 2014.

All scientific and technical information in this press release had been reviewed and approved by Dr. Warren Pratt (CGeol), a Director of the Company, who is a "Qualified Person" under Canadian National Instrument (NI) 43-101.
