CALGARY, ALBERTA--(Feb. 28, 2012) - 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 five holes totalled 1546.1 meters (m) and were designed to test the high grades announced in the press release of 26 January 2012.
The best results are from holes CA-12-19 and CA-12-21. CA-12-19 returned two separate high grade intervals: 9.4 m at 4.889 grams per tonne (g/t) gold and 2933.5 g/t silver and 6.1 m at 5.939 g/t gold and 1910.0 g/t silver. Both occur within an overall interval of 55.5 m at 2.280 g/t gold and 1024.6 g/t silver.
Hole CA-12-21 returned 17.6 m grading 4.669 g/t gold and 403.0 g/t silver within an overall interval of 74.5 m at 1.701 g/t gold and 110.1 g/t silver.
Dr. Warren Pratt, Director of Sienna Gold Inc, comments, "The drill program at Callanquitas is proceeding very well. The structure, sub-vertical and north-striking, is being cut where predicted in most holes and high grade oreshoots have now been demonstrated. All 5 drill holes in Section 4600N, which includes CA-12-19, intersect multi-kilogram silver and significant gold grades. This oreshoot appears to continue from surface to a depth of at least 400 m. Furthermore, the latest hole, CA-12-21, is located about 370 m farther south. The high silver and gold grade suggests this is another oreshoot.
These oreshoots allow us to add gold/silver ounces quickly to the resource. We are now focusing on the oreshoots and reducing drill centres to approximately 50 m, both vertically and laterally. This will define the oreshoots better and give higher confidence in the eventual resource calculation."
A map showing the location of these new intercepts is shown below. All significant intersections are given in the table below. Further maps and cross sections are available on the website:
