Sienna Gold Inc.: Further Success at Callanquitas: 11.1 Meters at 3.5 Grams per Tonne Gold
CALGARY, ALBERTA--(Marketwire - Sept. 4, 2012) - Sienna Gold Inc ("Sienna" or the "Company") (TSX VENTURE:SGP) (LMA:SGP) is pleased to announce the latest results from new drill holes at Callanquitas, on the Igor project, La Libertad, Peru. The ten holes totalled 1393.7 meters (m).
Drill Results
The best results came from Hole CA-12-65 with 11.1 metres (m) at 3.5 grams/tonne (g/t) gold and 35 g/t silver within an overall interval of 19.4 m at 2.2 g/t gold and 33 g/t silver
Drill hole CA-12-61 cut a number of mineralized zones: 2.55 m at 3.3 (g/t) gold and 7 g/t silver, 11.2 m at 1.2 g/t gold and 86 g/t silver and 9.4 m at 1.6 g/t gold and 59 g/t silver.
Full results are given in the table below. A map of drill hole locations is shown below, as is Section N4440. Further maps and cross sections are now available on the Sienna website.

The Callanquitas Structure
Dr Warren Pratt, Director of Sienna, comments, 'These excellent results come from drill holes that are widely distributed along the Callanquitas Structure. Mostly of 'step-out' character, they confirm the continuity of the structure and will contribute to the resource calculation, expected in late October 2012. These results come from shallower portions, where silver grades are lower. Significant portions of the Callanquitas Structure remain untested by drilling.'

Exploration Update
One man portable rig remains on site. A total of 15,000 m has been drilled to date.
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.
Drilling will, however, continue at Callanquitas and extend to Domo and Tesoros in late 2012/early 2013.
