Sienna Gold Inc. ("Sienna" or the "Company") (TSX VENTURE:SGP) (LMA:SGP) is very
pleased to announce results from the latest drill holes at Callanquitas on the
Igor project, La Libertad, Peru. The six holes totalled 1548.85 meters (m).
The best results are from Hole CA-12-27 which returned 17.6 m at 3.082 g/t gold
and 251.1 g/t silver within an overall interval of 48.7 m at 1.317 g/t gold and
141.2 g/t silver.
Holes CA-12-22 and CA-12-25 are also significant. They are located at the
current known northern and southern limits of the Callanquitas Structure.
CA-12-22 returned 2.8 m at 4.481 g/t gold and 48.6 g/t silver within an overall
interval of 25.5 m at 0.895 g/t gold and 19.4 g/t silver. Hole CA-12-25 returned
3.5 m at 3.007 g/t gold and 46.5 g/t silver within an overall interval of 10.4 m
at 1.290 g/t gold and 21.0 g/t silver.
The Callanquitas Structure
Dr. Warren Pratt, Director of Sienna Gold Inc, comments,
"These new results are very significant. Firstly, they keep demonstrating the
continuity of the Callanquitas Structure over at least 900 m of strike length.
Secondly, hole CA 12 27 now establishes the presence of a major high grade zone,
with many multi-kg silver grades, in the centre of the Structure. This zone has
now been cut to more than 400 m depth at 50 m vertical intervals. Step-out
drilling to the north and south has the potential to expand this high grade
zone. We will also focus on other potential high grade zones within the
structure."
A map showing these new intercepts is presented below. Further maps and cross
sections are available on the Sienna Gold website.

Exploration Update
Two rigs are on site: one large tracked rig and a man portable rig. To date, a
total of 6,700 m has been drilled as part of the current campaign of
10,000-12,000 m for Callanquitas and 3,000 m at Domo and Tesoros.
A new NI 43-101 resource calculation is planned for late 2012.
Sampling Methodology
Cores taken from the diamond drill rig are stored in plastic core boxes and
transported to the camp for detailed geotechnical and geological logging.
Density measurements and Point Load tests are carried out. Afterwards, the core
is cut on site with a diamond saw.
One half is then sent to an accredited laboratory in various sample lengths.
Randy Henkle (PGeol), the Company's independent Qualified Person, completed a
chain of custody review to ensure the integrity of all sample data.
Assaying Methodology
The samples are analysed by SGS Laboratories in Lima by inductively coupled
plasma atomic emission spectroscopy for silver and 37 other elements (included
Hg and Te) and a 30 gram fire assay technique for gold. Samples above detection
limits are re-assayed using a gravimetric fire assay. The specific lab
procedures can be found in the Company's 43-101 report on the Igor property.
This press release was reviewed and approved by Dr. Warren Pratt (CGeol) who is
a "Qualified Person" according to National Instrument 43-101.
Sienna Gold Inc. is a gold exploration company with property interests in Peru.
Its key prospect is the Igor Mine Project, a formerly producing mine that the
Corporation plans to explore further.
