CALGARY, ALBERTA--(Marketwire - Oct. 3, 2012) - Sienna Gold Inc ("Sienna" or the "Company") (TSX VENTURE:SGP) (LMA:SGP) is pleased to announce results from drill holes at Callanquitas, on the Igor project, La Libertad, Peru. The eight holes totalled 1170.65 meters (m). These are the last results to come in from the campaign, which comprised 65 drill holes with a combined meterage of 14,924.05 m.
Drill Results
The best results came from CA-12-67 with 7.7 metres (m) at 4.3 grams/tonne (g/t) gold and 58 g/t silver within an overall interval of 16.0 m at 2.2 g/t gold and 35 g/t silver.
Drill hole CA-12-70 also produced interesting results from a number of mineralized zones: 4.0 m at 1.8 (g/t) gold and 190g/t silver and 2.15 m at 2.5 g/t gold and 88 g/t silver.
Multiple mineralized zones were also intersected in Drill hole CA-12-68. These include 0.75 m at 8.2 g/t gold and 98 g/t silver and 1.9 m at 3.9 g/t gold and 12 g/t silver.
Full results are given in the table below. A map of drill hole locations is shown below.

The Callanquitas Structure
Dr Warren Pratt, Director of Sienna Gold Inc, comments, "We are very happy with progress. The Callanquitas drill program is now complete. As shown early on, the Callanquitas Structure maintains excellent continuity. These final drill holes were mostly designed to test the shallowest part of the structure (top 50 m), and were drilled at very shallow angles. The resource estimate is expected within a few weeks. Long sections, showing grades and true widths, will be published shortly. Meanwhile, additional, parallel structures are being mapped and sampled to generate new drill targets."

| (1)It should be noted that these are all angled holes and downhole intervals do not necessarily reflect the true width of the mineralized structure. |
| (2)Weighted averages were calculated for continuously mineralized intervals using a bottom cut on 0.1-0.2 g/t gold, no top cut and minimum internal waste. |

Exploration Update
Drilling has finished with a total of almost 15,000 m being drilled as part of the current campaign.
Work is focusing on the new resource for the Callanquitas Structure, based on approximately 20,000 m of drilling, should be published in mid- to late October with the full NI 43-101 report to follow before the end of the year.
Mapping and sampling on the project continues with the main focus on new mineralized structures around Callanquitas. Drilling will resume on the project in late 2012/early 2013.
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 and Point Load testing 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.
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 is exploring further.
