Sienna Gold Inc.: Surface Sampling at Callanquitas Yields More High Grade Gold and Silver Mineralization

Environmental Impact Assessment (EIA) for Drilling Approved by the Ministry

CALGARY, ALBERTA--(Marketwire - Nov. 3, 2011) - Sienna Gold Inc. (TSX VENTURE:SGP) (BVLAC:SGP) is pleased to announce the results of recent surface sampling around, and along, the Callanquitas Structure on the Company's Igor project in Peru. The samples confirm the high grade gold and silver potential of the structure.

Sampling Assay Results

A total of 82 samples were collected along the main Callanquitas Structure, mostly from new drill access roads. Secondary structures, parallel to the Callanquitas Structure, were also sampled. Seventeen samples contained more than 0.5 grams/ton (g/t) gold whilst 15 were equal to, or greater than, 1 g/t gold. Eight samples contained more than 31 g/t silver.

Most significant samples

Sample No Gold g/t (ounces ) Silver g/t (ounces )
I237674 34.3 (1.10 ) 57.0 (1.83 )
I237673 24.7 (0.79 ) 73.0 (2.34 )
I238669 10.5 (0.33 ) 70.5 (2.27 )
I237677 3.7 (0.12 ) 177.0 (5.69 )
I237679 7.6 (0.24 ) 146.0 (4.69 )

Drilling Permit

The Peruvian Ministry of Energy has approved the Company's proposed drill program for 2011-2012. The first drill rig has mobilized and two more drilling rigs are destined for the project before the end of the year.

Further details of the company's planned campaign of approximately 15000 m will be detailed in a future press release.

Sampling Methodology

Sampling was carried out on surface outcrops, structures, and underground workings (adits). All samples are from areas not previously sampled.

Wherever possible, channel samples were taken. If this was not feasible, chip samples were collected. Each sample was between 2 and 3 kg. Samples were collected under the supervision of a geologist from Sienna Minerals (a wholly owned subsidiary of Sienna Gold Inc) who marked the areas and sections to be sampled, checked the sampling method, numbered the samples, and did the corresponding descriptions.

Rigorous QA/QC procedures have been followed during the sampling program with either a standard, blank or duplicate inserted every 9th sample. Samples were shipped to ALS Chemex in Trujillo and analysed by ALS Chemex in Lima.

Assaying Methodology

The samples are analysed by ALS Chemex Laboratories in Lima by inductively coupled plasma atomic emission spectroscopy for silver and 33 other elements and a 30 gram fire assay technique for gold. Samples above detection limits are re-assayed using a gravimetric fire assay technique. 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), a director of Sienna Gold Inc and 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 Company plans to explore further.
